L-2011-209 Enclosure Page 1 of 3 Enclosure - FPL/NextEra's Responses to Requests for Additional Information
: 1.      Assumptions used regardingescalation in decommissioning costs, rate of earnings on decommissioning funds and rates of other factors used in funding projections Within the DFS report, it was stated that FPL, as well as the other owners, are allowed to assume rates used regarding the rate of escalation in decommissioning costs, rates of earnings on decommissioning funds and rates of other factors used in funding projections.According to 10 CFR 50. 75(f)(1):
The information in [the DFS] report must include [...] the assumptions used regarding rates of escalation in decommissioning costs, rates of earnings on decommissioning funds, and rates of other factors used in funding projections...
Provide a citation (e.g., an Order by the rate-regulatory authority) for the regulatory entity's authorityto set the rates used in the DFS report.
FPL/NextEra Response to Question 1 FPL's Decommissioning Funding Status (DFS) reports for St. Lucie and Turkey Point reflected real rates of return taken from FPL's decommissioning cost study that was filed with the Florida Public Service Commission (PSC) in December 2010. The real rates of return cited in the FPL DFS reports were: 1.06% (St. Lucie Unit 1); 1.16% (St. Lucie Unit 2); and 0.95% (Turkey Point Units 3 and 4). Those real rates of return have not been formally approved by the PSC. FPL cited the non-approved rates because they are lower than the 2 percent real rate of return allowed under 10 CFR 50.75(e)(ii), which allows licensees to "take credit on collected earnings up to a 2 percent real rate of return." That regulation requires an authorized rate only when a licensee takes credit for a real rate of return greater than 2 percent.
However, it is important to note that, while FPL included these proposed real rates of return in its DFS reports, it did not credit these rates of return. As shown in the FPL DFS reports, the decommissioning trust fund balances for St. Lucie Units 1 and 2, and Turkey Point Unit 4 as of December 31, 2010 currently meet the NRC minimum value calculated in accordance with 10 CFR 50.75(c). This is true both when utilizing the total commingled fund reported in paragraph 2 of each DFS report and when utilizing the proportional balance from the site-specific cost studies as shown in "Attachment 2" to each of those 3 DFS reports. This proportional method is described more fully in the response to Question 2.
Turkey Point Unit 3 currently meets the NRC formula minimum when utilizing the total commingled fund reported in paragraph 2 of its DFS report and is within approximately
$22 million of the NRC formula minimum when utilizing the proportional balance from the TLG cost study as shown in "Attachment 2" to its DFS report. For completeness, FPL has provided herein, as Attachment 1, a report escalating the Turkey Point Unit 3 decommissioning trust fund balance allocation based on the site-specific cost study using the 0.95% proposed real rate of return. This demonstrates that, in addition to the commingled fund already meeting the NRC formula minimum, the proportional allocation

L-2011-209 Enclosure Page 2 of 3 attributable to NRC license termination costs also meets the NRC formula minimum when crediting a 0.95% real rate of return, as allowed by regulation.
Contributions to the decommissioning trust funds for Seabrook Station are determined on an annual basis by the New Hampshire Nuclear Decommissioning Financing Committee (NDFC). The most recent NDFC order, from Docket No. 2010-1 is provided herein as Attachment 2. The Order approved nominal rates of return as follows:
: a. Equity = 9.5%
: b. Bonds = 6.0%
: c. Cash and cash equivalents (long-term) = 3.5%
The Order also approved an inflation escalation adjustment of 4.2% applied to the cost of decommissioning. Authority for the NDFC to regulate decommissioning accruals is found at New Hampshire Statutes Chapter 162-F, "Decommissioning of Nuclear Electric Generating Facilities."
: 2.       Citation for Site-Specific Study On March 23, 2011, FPL only provided the total dollar amounts, not a year-by-year breakdown of site-specific cost estimates for St. Lucie I and 2, Turkey Point 3 and 4, and Seabrook, for the amount of decommissioning funds estimated to be required.
Pursuant to 10 CFR 50.75(e)(1)(i) and (ii), the licensee must specifically describe the safe storage period in order to take credit for projected future earnings when it uses a site-specific estimate as the basis for using the prepayment or external sinking fund methods of financial assurance.
Provide the site specific cost estimates for St. Lucie I and 2, Turkey Point 3 and 4 and Seabrook, unless they were previously submitted to NRC. If the cost estimates were previously submitted to the NRC, then provide a reference to the submittals. The site specific cost estimates should include a summary schedule of annual expenses, projected earnings, and end-of-year fund balances, expressed in 2010 dollars.
FPL/NextEra Response to Question 2 In "Attachment 2" to the DFS reports for St. Lucie, Turkey Point, and "Attachment 3" to the DFS report for Seabrook, FPL/NextEra referenced site-specific cost studies prepared by TLG. The citation of these site-specific cost studies was not intended to reflect a decision to utilize an alternative funding amount under 10 CFR 50.75(b)(1). Each of these specific DFS reports relies upon the NRC minimum formula calculated under 50.75(c).
The Turkey Point, St. Lucie, and Seabrook decommissioning trust funds include nonsegregated funds accrued to account for spent fuel management and site restoration costs in addition to nuclear decommissioning (license termination) costs. In 2008, the NRC explained in a letter to FPL that "[b]ecause [it] does not earmark the three cost components, FPL should be reporting all funds within the external trust to the NRC as radiological decommissioning (license termination costs)." Letter from B. Mozafari, NRC to J.A. Stall, FPL, St. Lucie Plant, Unit Nos. 1 and 2 - Biennial Decommissioning Funding Report (TAC Nos. MD9354 and MD9355), dated Nov. 26, 2008 (ADAMS

L-2011-209 Enclosure Page 3 of 3 Accession No. ML082800278). Accordingly, in paragraph 2 of the DFS reports, FPL and NextEra reported the entire fund balance as the amount accumulated at the end of the calendar year preceding the date of the report.
The NRC has also issued guidance in RIS 2001-07, Rev. 1, '10 CFR 50.75 Reporting and Recordkeeping for Decommissioning Planning" (2009) explaining that licensees should identify when accounts are not segregated and provide an accounting of the amounts attributable to the various cost components. To this end, FPL and NextEra cited the cost studies that are relied upon by the relevant state regulatory bodies in order to reflect a reasoned accounting of the three cost components and determine the percentage that could be reasonably attributable to NRC license termination costs. This approach, allocating the trust fund balance based upon the percentage of the total cost attributable to license termination activities as reflected in the cost study, was also utilized in FPL's response to an RAI in 2010. Letter from L. Nicholson, FPL to NRC Document Control Desk, "Response to Request for Additional Information," May 25, 2010 (ADAMS Accession No. ML101470054).
Copies of the St. Lucie and Turkey Point cost studies relied upon for this purpose in FPL's DFS report are provided herein as Attachments 3 and 4, respectively. The Seabrook cost study is provided herein as Attachment 5.
: 3.       Any material changes to trust agreements In FPL's DFS report, FPL did not explicitly state if there were any material changes to the trust fund agreements for Point Beach 2. According to 10 CFR 50. 75(f)(1), each power reactorlicensee shall report ... for each reactoror part of a reactorthat it owns ...
any material changes to trust agreements. Provide a discussion of whether there were any material changes to the trust fund agreements for Point Beach 2.
FPL/NextEra Response to Question 3 NextEra's DFS report for Point Beach Unit 2 inadvertently omitted the page that reported whether there were material changes to the trust fund agreement. The missing page is provided herein as Attachment 6.

NDFC 2010-1 PRELIMINARY REPORT AND ORDER I. 

==SUMMARY==
OF FINDINGS The Nuclear Decommissioning Funding Committee (NDFC or Committee) conducted the annual review of the Decommissioning Trust Fund (Decommissioning Trust or Trust) as required by RSA 162-F:22.      The Committee considered the evidence presented and made the findings that are summarized here. In preparing the Schedule of Payments for 2011, the following assumptions are to be used.
: 1. The Funding Date for all Seabrook Owners, as defined by RSA 162-F:14 VII, is 2030.
: 2. Decommissioning is assumed to begin in 2030 and be completed in 2101 with the removal of the Independent Spent Fuel Storage Installation (ISFSI).
: 3. The projected cost of decommissioning, when expressed            in 2010 dollars, is
           $1,003,372,473.
: 4. Onsite storage of spent nuclear fuel (SNF) and Greater-Than-Class C (GTCC) radioactive waste in the ISFSI is assumed until 2100, with the ISFSI dismantled in 2101.
: 5. The inflation adjustment applied to the schedule of payments will remain 3.0%, as set in NDFC Docket 2007-1.
: 6. The escalation adjustment applied to the cost of decommissioning will remain 4.2%,
as set in NDFC Docket 2007-1.
: 7. The Decommissioning Trust earnings assumptions for each Seabrook Owner are:
: a. Equity assumed earning rate = 9.5%
: b. Bonds assumed earning rate = 6.0%
: c. Cash and cash equivalents (long-term) assumed earning rate       =
3.5%
These are the assumed earning rates approved by the NDFC in NDFC Docket 2008-1.
: 8. The Trust investments of each Seabrook Owner, for all years, are assumed to be the same as the actual investments on November 30, 2010.
: 9. The funding assurances from NextEra Seabrook, LLC (NextEra), as established in NDFC Docket 2002-2, will remain unchanged.
1
: 10. The Funding Assurance Escrow (Escrow) established in NDFC Docket 2003-1 will continue to be used for the Seabrook Station Owners.
: 11. Monies held in the Escrow are assumed to earn 0.25% during 2011 and 2012.
: 12. All amounts held in the Escrow are assumed to be transferred to the Trust in 2013.
The schedules of payment shall be calculated assuming that 100% of contributions for all Joint Owners are deposited in the Escrow in 2011 and 2012. All annual contributions made subsequent to 2012 are assumed to be deposited directly into the Trust.
The Committee's findings are discussed in detail below.
II. PARTIES AND THEIR POSITIONS The Massachusetts Municipal Wholesale Electric Company (MMWEC), NextEra Seabrook, LLC as managing agent of Seabrook Station (NextEra or Managing Agent), Taunton Municipal Lighting Plant (Taunton) and Hudson Light and Power Department (Hudson) are the only entities that participated in this docket. The Managing Agent represented NextEra, Taunton and Hudson throughout the docket. MMWEC was represented throughout the docket by their own counsel..1 The parties presented a Stipulation of the Parties (Stipulation) (Exhibit No. 2) at the public hearing on September 8, 2010. The Stipulation addressed each issue identified within the scope of this docket, in NDFC Docket 2010-1 Order No. 1. The Stipulation identified a list of exhibits the parties proffered at the public hearing (Exhibits Nos. 12 - 14), and identified the hearing witnesses for the Seabrook Owners with a sworn affidavit from each witness.
III.      PROCEDURAL HISTORY The Order of Notice initiating this docket was issued on March 19, 2010. The Managing Agent filed the 2010 Annual Report (2010 Annual Report) on March 31, 2010 (Exhibit 1).
Timely notice of the docket was provided to the public by publication in the N.H. Union Leader and in the Hampton Union on March 26, 2010. The notice was also posted at the office of the Seabrook Town Clerk and the Seabrook Community Center on March 26, 2010.
'Collectively, the parties are referred to as "Seabrook Owners."

The first pre-hearing conference was held on April 28, 2010. On May 6, 2010, the NDFC issued Order No. 1, which set forth the procedural schedule and scope for the docket. Four (4) pre-hearing conferences were held before the public hearing, with counsel for the NDFC presiding as the hearing officer. A Stipulation of the Parties (Exhibit No. 2) was submitted, and executed copies the Stipulation were delivered, at the public hearing on September 8, 2010.
The Seabrook Owners presented two witnesses at the September 8, 2010 public hearing.
Mr. Alan Smith's Affidavit supported of the Stipulation of the Parties and further addressed Seabrook Station's operating history and the financial performance of NextEra Seabrook, LLC (NextEra Seabrook). Additionally he provided an update of NextEra Seabrook's request for credit regarding it Settlement Agreement with the Department of Energy, and a summary of its request for a limited contribution deferral.       Mr. Michael O'Keefe testified on behalf of the Seabrook Owners regarding operation of Seabrook Station. The Stipulation included a sworn affidavit of Mr. Alex Weiss attesting to the financial health of NextEra and its parent entities.
Mr. Weiss did not testify during the public hearing. During the public hearing, NDFC members requested additional information from the witnesses.            The requested information will be presented during the second public hearing to be held in Seabrook, New Hampshire (Seabrook Hearing). The requested information is identified in Chart 2.
The exhibits accepted at the hearing were:

During the hearing NDFC members requested additional information from the witnesses, to be provided as post-hearing submissions. Exhibit numbers were reserved for the additional information, and NextEra provided the information to NDFC counsel on Monday, September 20, 2010. Exhibit numbers were assigned, and NextEra will present to exhibits at the Seabrook Hearing for inclusion in the record of this docket. The hearing exhibits are identified in Chart 2.

DISCUSSION The annual review this year reviewed was conducted with the continued overarching concern that the economic downturn and investment loses by the Trust raises concerns about the sufficiency of the Trust. As shown in Chart 3, the Trust was subject to losses during the past four years, even after additional annual contributions were made.           A review of Chart 3 demonstrates that the Trust and Escrow combined are nearly equal to the Trust balance at the end of 2006.

Exhibit 1, Seabrook Station 2010 Annual Report at 4-5.       Also, the Seabrook Owners believe the Nuclear Regulatory Commission (NRC) will extend the operating license by twenty years, which will result in the Trust being overfunded, if the present earning and cost assumptions are employed.
TR. at   _. While the NDFC appreciates their perspective, the Committee is obligated to 5

establish the ability to meet decommissioning obligations, even in the event of premature permanent cession of operation. RSA 162-F:19 IV. While funding assurances are in place and can be called upon, the Committee remains concerned that the funds dedicated to meet decommissioning obligations are lagging due to the losses experienced since 2006.
In NDFC Docket 2007-1, the NDFC decided that, in the event of premature permanent cessation of operation, actual demolition of Seabrook Station would begin in 2020. NDFC Docket 2007-1, Final Report and Order at 35. This determination was based on the need for the completion of a NRC-approved site-specific decommissioning plan, and sufficient time for the Seabrook Owners to contribute additional funds sufficient to complete prompt decommissioning, as required by RSA 162-F: 21-c. This determination assumed that the Trust would continue to grow and that, by 2020, 75% of the projected cost of decommissioning would be in the Trust.
This projection was provided by the Seabrook Owners as part of the NDFC Docket 2007-1.

As can be seen in Chart 5, the expected 2020 Trust Fund balances have declined as the effect of the loss in earnings have been realized.

The NDFC will not address the assumption that decommissioning would commence in 2020 in the event of permanent premature cessation of operation nor, at this time, require additional payments into the Trust.       However, the NDFC is concerned that the ability to 6

commence decommissioning in 2020, if needed, would require a significant infusion of funds.
Therefore, the Seabrook Owners can expect that the ratio of projected Trust Fund balances when compared with the projected cost of decommissioning will be of particular interest during the comprehensive review in 2011.
: 1. NextEra's 2011 Obligation NextEra requested that its 2011 decommissioning obligation be deferred. See: Exhibit 2 at 6, TR. at _. In summary, NextEra's request is based on the Company's belief that the NRC will extend the operating life of Seabrook Station, and then NextEra's Trust will be overfunded, if the station operates for its revised full license life. NextEra committed to make monthly payments, including all deferred monthly payments, immediately upon a directive from the NDFC, without additional hearings. TR. at    _. MMWEC opposed NextEra's request. Exhibit 2 at 10, TR. at     _. The remaining Seabrook Owners did not express a position regarding NextEra's request.
NextEra's seeks to retain funds for use by the company, rather than having the funds held in the Escrow or the Trust. During the public hearing, Mr. Smith addressed the financial health of NextEra and its parent companies.         TR. at   _. NextEra's desire to retain funds is understandable but the Committee is unprepared in these circumstances to permit any Seabrook Owner to defer contribution obligations.      The Committee's decision is based on the under-performance of the Trust and the continued economic uncertainty.          The Committee is also mindful of its obligation to ensure funding of decommissioning, even in the event of permanent premature cessation of operation, which requires the NDFC to anticipate adverse circumstances for any Seabrook Owner.         As noted below, NextEra will be required to deposit its 2011 obligation in the Escrow, providing the NDFC with the means to release funds to the company at a future date.
: 2. Funding Assurance Escrow The NDFC created the Funding Assurance Escrow (Escrow) in NDFC Docket 2003-1 and used it with success in each subsequent year. The Escrow is one method used by the NDFC to assure full funding of the decommissioning obligation, while also respecting that monies 7

deposited in the Trust can not be returned to the Seabrook Owners until all decommissioning is completed.      The Escrow is controlled by the NDFC, which permits release to the Seabrook Owners at the direction of the Committee.          2 The Escrow also provides a means for a quick cash infusion into the Trust, should the NDFC determine the need.               In 2007, the NDFC released $10 million to FPLE Seabrook, based in large part on projected overfunding in future years.                       In NDFC Docket 2009-1, the funding obligations of all Seabrook Owners were deposited in the Escrow, and the owners request the same treatment this year. 3 The Seabrook Owners requested that all 2011 contributions be deposited in the Escrow. Exhibit 2 at 7, TR. _.
The NDFC will continue the practice of having all 2011 decommissioning payments deposited in the Escrow.          The schedules of payment shall be calculated assuming all future contributions through 2012 are also deposited in the Escrow, and assume that all funds held in the Escrow are transferred to the Trust in 2013.
The Escrowed funds are held in cash and cash-equivalent investments that can be readily converted to cash should the NDFC decide to transfer monies to the Trust.                       Presently, it is assumed that funds held in the Escrow earn 1.75% per annum.                       While the assumption was reasonable when first established, experience convinces the NDFC that continuing to employ that assumed rate of earnings overstates the likely earnings for the Escrow. Exhibit 10 presents a multi-year history of the Vanguard Money Market Fund in which the Escrow funds are held.
When considered over a three year period, the money market fund provided a 1.80%, but on 0.22% over a one year period. Returns during 2010 were 0.13%.
As noted, the NDFC assumes that the Escrow will either be transferred to the Trust or released to the Seabrook Owners in 2013. While this assumption may change, it underscores that the Escrow is intended to be a short term funding assurance, which supports using short term earnings assumptions. In view of the actual experience of the money market fund, the NDFC believes that it is no longer prudent to assume monies in Escrow will earn 1.73%. Instead, the Committee will assume that 0.25% will be earning on the Escrow, and directs that this new assumption be used in calculating earnings in the Escrow in 2011 and 2012.
2 Monies held in the Trust can only be released to Owners after all decommissioning is completed.
3 NextEra's request for deferral of the 2011 payments are addressed separately.

: 3. Trust Investment Assumptions Each Seabrook Owner established goals for allocation of investments of their individual Trust monies, as permitted by the NDFC and within the Investment Guidelines as approved by the New Hampshire State Treasurer. As shown in Exhibit 11, MMWEC, Hudson and Taunton have not achieved the level of equity investments that are the basis of the assumed earnings for their respective Trust investments. Chart 6 provides an extract from Exhibit 11.
CHART 6 ACTUAL VS. ASSUMED EQUITY INVESTMENTS Hudson  MMWEC         Taunton Actual Equity % of Portfolio at 7/31/10        18.21%   46.76%        18.75%

Source: Exhibit 11 In response to questioning by NDFC members, the Seabrook Owners provided Exhibit 14:   Equity Allocations. The exhibit presented the intentions of the three minority Seabrook Owners, as summarized in Chart 7.
CHART 7 PROJECTED YEAR END PERCENTAGE OF EQUITY INVESTMENTS IN TRUST FUNDS 2010             2011         2012 MMWEC                    55%             60%          65%
Taunton                  30%             30%          30%
Hudson                   30%             30%          30%
Prior to being permitted to deposit annual contributions in the Escrow, these Seabrook Owners were moving towards the targeted equity investments by investing all new monies in equity investments in their respective Trusts. The owners failed to realign investment strategies when they stopped making deposits to the Trust. See: Exhibit 14.
The response provided by Exhibit 14 expresses the intent of each minority owner to achieve the allocations summarized in Chart 7. The NDFC prefers to rely on actual information when available. Accordingly, the Committee directs that the Managing Agent to produce the 9

schedules of payments for 2011 using the actual Trust investment portfolio of each owner as of November 30. The Managing Agent is to assume that the Trust investment portfolio of each Seabrook Owner remains unchanged for 2011 and every following year during the operating license life. After surrender of the operating license, the assumed transfers to cash and cash equivalents to meet the decommission era cash coverage ratios should be applied, as previously established by the NDFC. This approach will avoid either overstatement of projected earnings based on allocation of investments, or the undervaluation of the Trust that would result from a failure to credit accomplishment of reallocation goals.
: 4. The Projected Cost of Decommissioning The projected cost of decommissioning was established in NDFC Docket 2007-1 at the completion of a comprehensive review of the Seabrook Station decommissioning plan and cost estimate, pursuant to RSA 162-F:22, I. The projected cost of decommissioning is defined as the current best estimate of the cost to promptly begin decommissioning Seabrook Station at the end of its licensed operating life in 2030. The decommissioning cost is escalated annually to maintain a current projected cost of decommissioning.      In 2011, the NDFC will once again determine     the projected   cost   to decommission    Seabrook    Station,   based   on a new decommissioning cost study. In 2011, the NDFC will also undertake a comprehensive review of the    decommissioning     plan   and   all assumptions   employed     in   the   estimating how decommissioning monies held in the Trust will be invested and returns that will be realized. The Committee was advised at the public hearing in NDFC Docket 2009-1 that the decommissioning cost study will be prepared by TLG Services, the same firm that prepared each of the prior decommissioning cost studies.
The Committee will continue to use the projected cost of decommissioning as accepted in 2007, adjusted to be presented in current dollars, pending the completion of the 2011 comprehensive review.        Accordingly, the present projected cost of decommissioning is
$1,003,372,473, when expressed in 2010 dollars.
10
: 5. Funding Date The funding date is the year in which contributions into the Decommissioning Trust may end because the NDFC believes "the fund shall have sufficient monies to complete decommissioning" on the schedule of payments approved by the NDFC. RSA 162-F:14, V. In NDFC Dockets 2007-1 and NDFC 2008-1 the Committee established 2030 as the funding date for Seabrook Station. No party requested any change to the funding date, and the Committee finds no reason to adjust the funding date at this time.
: 6. NextEra Name Change On May 21, 2010, FPL Group, Inc. changed its name to NextEra Energy, Inc.                           FPL Group, Inc. was the parent of NextEra Seabrook, LLC and directly responsible for the decommissioning obligations of NextEra, pursuant to the funding assurances established in 2002. to Exhibit 4 of the Stipulation (Docket Exhibit 2) provides a corporate flowchart and identifies the current names of the entities that comprise the NextEra Energy family. The name change from FPL Group, Inc. to NextEra Energy, Inc. was duly approved by the corporate board and filed with the State of Florida. 4 Review of the relevant board resolutions confirms that the change of name did not dissolve any of the obligations of the parent to provide funding assurance to NextEra.
: 7. Funding Assurances Funding assurances are required of all non-utility owners of Seabrook Station. RSA 162-F:21-a, 1II. The NDFC may impose a funding assurance requirement to ensure recovery of decommissioning costs in the event there is a premature permanent cessation of operation. RSA 162-F:19, IV. In NDFC Docket 2002-2, the NDFC established funding assurance requirements for NextEra, which included a guaranty by its indirect parent company, FPL Group Capital, Inc.,
which in turn is backed by a guaranty by the holding company, FPL Group, Inc. To ensure full funding of the decommissioning obligation, the Committee established "triggers" that would 4 The Managing Agent provided the NDFC with a Secretary's Certificate, dated June 21, 2010, confirming the name change and providing a copy of the board resolution and the written consent of NextEra Seabrook LLC to the change.

Similarly, Seabrook Station continues to perform well than the industry averages. TR.            _. The NextEra funding assurances will be reviewed during the comprehensive review to be conducted in 2011.
In NDFC Docket No. 2008-1, at 21 - 29, the Committee determined that Taunton, Hudson and MMWEC have contractual and statutory obligations that cannot be voided, even through employment of the Bankruptcy Code, and that additional funding assurances were not required of those Seabrook Owners.        The Committee is satisfied that those obligations are sufficient at this time so that no additional funding assurances are required from the minority Seabrook Owners.
: 8. Schedules of Payments: December Re-set and Earnings Assumptions In Docket 2002-2, the NDFC established the practice of setting the schedules of payments beginning on January 1 of the following year based on a November 30 actual Trust balance, adjusted to estimate the end-of-year balance as closely as possible. In Docket 2004-1, the year-end calculation was further refined and was again adjusted in Docket 2009-1 to include the Escrow balances, and assumed expenses in December, in determining future annual contributions. This approach permits the best full-year estimate of earnings and expenses during the year to be recognized when setting contribution requirements for the next year. This practice has come to be known as the "December true-up."             This annual adjustment is particularly appropriate during times of uncertain earnings, such as have been experienced for the past three years. Accordingly, the NDFC will continue to employ the December re-set of the schedules of payments to establish the obligations in 2011.

: 9. 2011 Annual Report The Managing Agent is directed to deliver the 2011 Annual Report by March 31, 2011.
The scope and components of the Annual Report have evolved over many years, leading to the possibility of confusion as to the required content. To clarify the requirements for the Annual Report, the following is the information required by the NDFC.          The Seabrook Owners remain free to provide additional information they believe would assist the Committee in its annual review.      In NDFC Docket 2009-1 specific requirements for the decommissioning study were set forth, and the Managing Agent committed to provide that information. In addition, the Annual Report must include the following information:
A. Seabrook Station Performance including any changes regarding the status of the ISFSI and nuclear industry B. Status Of Low Level Radioactive Waste Disposal C. Status Of High Level Radioactive Waste Disposal D. NextEra Energy, Inc. Financial Performance E. Joint Owner Trust Investment Strategy F.

CONCLUSION Based on this Preliminary Report and Order, the Committee finds that the requirements of RSA 162-F for funding decommissioning will be met by implementing the requirements set forth in this order.
Based on the foregoing, it is hereby ORDERED, that the funding assurance provided by NextEra approved in the Docket 2002-2 Final Report and Order shall remain in place and unchanged, and that no additional funding assurances are required from other Seabrook Owners at this time; and it is FURTHER ORDERED, that each Seabrook Owner shall deposit 100% of its 2011 contribution into the Funding Assurance Escrow; and it is FURTHER ORDERED, that payments into the Funding Assurance Escrow are funding assurance obligations, and are not a schedule of payment obligations of the Seabrook Owners.
Payments into the Escrow are obligations imposed by the NDFC and fully enforceable by the Committee; and it is FURTHER ORDERED, that the schedules of payments for 2011 will be established in December 2010, calculated using the Decommissioning Fund and Funding Assurance Escrow account market values and the actual Trust investment portfolios as of November 30, 2010; and it is FURTHER ORDERED, that the schedules of payments for 2011 will be calculated using the assumptions delineated in the Summary of Findings of this Preliminary Report and Order; and it is FURTHER ORDERED, that NextEra is to file, no later than March 31, 2011, an independent auditors' report on the Seabrook Nuclear Decommissioning Financing Fund and the Seabrook Escrow Fund as of December 31, 2010; and it is FURTHER ORDERED, that the 2011 Annual Report is to filed no later than March 31, 2011, and shall include all information delineated in Section IV 9 (2010 Annual Report), of this Preliminary Report and Order; and it is 15

FURTHER ORDERED, that any party to this proceeding wishing to comment on this Preliminary Report and Order shall file written comments with the NDFC no later than October 13, 2010, and provide a copy to all parties on the same date; and it is FURTHER ORDERED, that the date of the public hearing to be held in the Town of Seabrook will be held on Wednesday, October 27, 2010, commencing at 7:00 p.m. The location will be established with sufficient time for full disclosure pursuant to RSA 98-A and RSA 162-F.
This is a Preliminary Report and Order of the NDFC prepared in conformity with RSA 162-F:21, 1II. A Final Report and Order will be issued after the Committee has reviewed all comments received regarding this Preliminary Report and Order, and after the review of all comments submitted at the hearing to be held in the Town of Seabrook, New Hampshire.
This Preliminary Report and Order is released on September 24, 2010.

Florida Power & Light Company                                               Executive Summary 2010 Nuclear Decommissioning Study                                          Page 1 of 3 Overview FPL's 2010 Nuclear Decommissioning Study results are based on estimates and assumptions that follow Nuclear Regulatory Commission (NRC) requirements and industry guidelines for the development of the costs to remove and dismantle nuclear power plants decades into the future. Funds are maintained and interest reinvested in the decommissioning trusts as required by the NRC, Internal Revenue Service, Federal Energy Regulatory Commission and Florida Public Service Commission (FPSC). Under federal law, these funds may only be used for nuclear decommissioning, are not available for any other use and do not earn a return or profit for FPL. The study is essentially a snapshot, which shows that based on current assumptions FPL's nuclear decommissioning trust funds are appropriately funded and demonstrate that, despite downturns in the market, these funds are helping protect customers from potential future cost increases. Compared to 2005, the currently calculated funding position has improved primarily because of a decrease in the assumed escalation rate for future decommissioning costs, in addition to a reduction in the estimated nominal cost of decommissioning resulting from a settlement with the Department of Energy (DOE). FPL customers have not contributed to the decommissioning trusts since 2005, and the study confirms that, as of Dec. 31, 2010, the trusts continue to be adequately funded without FPL customer contributions.
Decommissioning studies represent the aggregation of numerous estimates for activities and costs that will not be incurred for at least 22 years. As such, they are highly dependent upon input assumptions that can and will change over time, such that future funding positions could differ substantially from today's position. Historical costs and investment returns over the last five years have actually had a negative impact on the funding position, but adjustments to assumptions regarding events that will occur far in the future drive the net improvement. The current assumed escalation rate is 1.6 percent lower than in the 2005 study, and the impact of this change is substantially greater than the entire difference in funding positions between 2005 and 2010, reaffirming the importance of maintaining adequate funding. For this reason, the FPSC and FPL should continue to review these studies on the scheduled basis to ensure that adequate funds are available to decommission FPL's nuclear plants at the appropriate time.
2010 Study Approach The information contained in this 2010 Decommissioning Study is presented in compliance with Rule 25-6.04365, Florida Administrative Code, and prior Commission Orders. FPL contracted TLG Services, Inc. (TLG), the leading provider of these services to the U.S. nuclear industry, to prepare its 2010 site-specific nuclear decommissioning cost analysis and comparison reports, which are estimated based on NRC requirements, industry guidelines, and prior experience.
TLG includes the most up to date actual decommissioning information available to ensure the methodology used to prepare the cost analysis is reasonable.
FPL selected a DECON (immediate dismantlement) decommissioning option for its units. The DECON method provides not only a lower cost, but also enables a coordinated sequence of decommissioning events, which allows for a one-time mobilization of contractor personnel and equipment. FPL's choice of the DECON method is consistent with the method in prior studies approved by the Commission for purposes of determining FPL's appropriate accrual and funding requirements.

Florida Power & Light Company                                               Executive Summary 2010 Nuclear Decommissioning Study                                          Page 2 of 3 Escalation Rate The 2010 Decommissioning Study assumes that future decommissioning costs grow at an average rate of approximately 3.0 percent per year. In contrast, the 2005 study assumed an average escalation rate of 4.6 percent. FPL notes that the current escalation rates are below any typical range due to the current macro economic market conditions that have reduced escalation factors to near all time lows. While FPL believes that the current escalation rates are reasonable for the purpose of the 2010 Decommissioning Study, it should be noted that subsequent changes in the assumed escalation rate are likely to be increases, which would result in higher projected future decommissioning costs.
Spent Fuel Management Consistent with prior studies and assumptions approved by the Commission, the decommissioning cost estimates include the cost associated with interim storage of spent nuclear fuel (SNF) on site until such time the DOE is able to remove SNF from the site.
Subsequent to the 2005 study, in 2009, FPL executed a Settlement Agreement with the U.S.
Government that resolved FPL's lawsuit for damages resulting from a DOE delay in commencement of disposal of SNF. The Settlement Agreement requires the Government to make payments to FPL to cover the cost incurred for managing and storing SNF that would not have been incurred but for DOE's delay in SNF disposal. As such and for purposes of this study, the DOE is expected to make payments to FPL to cover spent fuel management costs incurred by FPL prior to 2062, which is the date FPL currently projects that the DOE will meet its obligation to begin disposal of SNF. For purposes of the funding and accrual analysis contained in this study, the 2010 decommissioning costs have been reduced significantly to reflect the reimbursement by the Government of SNF management costs incurred during the decommissioning period. This is the first time expected Government reimbursements have been factored in to FPL's funding analyses and nuclear decommissioning studies. The ultimate timing and amount of reimbursements will depend on many factors, including but not limited to, the DOE's ability to receive SNF and the Government's compliance with the terms of the Settlement Agreement. Some state jurisdictions do not allow utilities to include SNF settlements in their decommissioning funding analyses due to the concern that reimbursements may not be guaranteed and may bias the result. FPL believes that the recognition of the SNF reimbursements should be included based on the fact that the Settlement Agreement is a binding legal agreement on the Government and FPL has successfully received SNF reimbursements pursuant to the Settlement Agreement.
Fund Earnings Rate Since 2005, FPL customers have not made contributions to the nuclear decommissioning trusts, but an adequate funding level has been maintained, as indicated in the estimates included in the 2010 study. This is despite investment returns totaling $133 million less than estimated in the 2005 study. FPL's current investment strategy for its nuclear decommissioning funds is largely consistent with its 2005 study. The economy remains weak; therefore, future investment results are uncertain.

Florida Power & Light Company                                               Executive Summary 2010 Nuclear Decommissioning Study                                          Page 3 of 3 Changes from 2005 to 2010 The changes in actual cost and actual returns since 2005 have reduced the funded status of FPL's four nuclear units by more than $195 million as of Dec. 31, 2010. These reductions have been offset primarily by reductions in assumed escalation factors for future decommissioning costs and, to a lesser extent, government reimbursements pursuant to the SNF settlement. As discussed above, the funding status is highly dependent upon the assumed escalation rates, which are currently assumed to be at near all-time lows and could increase significantly in the future.
Sensitivities FPL believes the assumptions used in the 2010 funding analyses are based on the best information available at the time the study was prepared, and represents a reasonable outcome.
However, due to the number of assumptions that must be made and the length of time before decommissioning will actually begin, it is important to understand a range of results can be produced using other assumptions. The following are examples of sensitivities that provide a high degree of uncertainty:
* Timing and amount of future DOE reimbursement under the SNF settlement (represents approximately 88 percent of the change in the funded position)
* Lower than anticipated fund earnings as a result of future market downturns
              " Increase in the escalation of burial costs
              " Increase in cost of nuclear decommissioning activities Conclusion The 2010 Decommissioning Study indicates that the trusts are currently at an adequate funding level given current assumptions and projections. These trusts are necessary so FPL's customers are adequately protected from further cost increases when the time comes to decommission FPL's nuclear plant. FPL has earned its customers trust by using careful, prudent investment strategies in all facets of its business including the management of its nuclear decommissioning trusts. Despite recent volatile markets, the funds remain secure. As a result, FPL's current annual expense accrual requirements for decommissioning costs presented in this study support a zero accrual and funding requirement as of Dec. 31, 2010.
In addition, as required by the Commission in Order Nos. FPSC-02-0055-PAA-EI and FPSC 0153-FOF-EI, FPL has updated its estimates for End of Life Nuclear Fuel Last Core and End of Life Materials and Supplies Inventory balances. This information is provided for informational purposes with this study. FPL is not requesting a change in accruals at this time. Rather, FPL believes that the results of these updated values for End of Life Nuclear Fuel Last Core and End of Life Materials and Supplies should be addressed in FPL's next base rate proceeding and that the appropriate changes in accruals, if any, should be made at that time.

Decommissioning Methods For purposes of this analysis, decommissioning is defined as the activity whereby nuclear facilities are removed safely from service and residual radioactivity is reduced to a level that permits release of the property for unrestricted use and termination of the operating license granted under Title 10 CFR Part 50. Decommissioning also includes the dismantlement, disposal and site restoration activities associated with the non-contaminated portion of the facilities. These activities are not required for termination of the operating license, but are required to address other non-radiological requirements associated with the release of the site.
The Nuclear Regulatory Commission (NRC) has defined three acceptable decommissioning methods: Prompt Removal/Dismantling (DECON); Safe Storage/Deferred Decontamination (SAFSTOR); and Entombment (ENTOMB). The study utilizes the NRC terminology, but also includes the additional activities required to accommodate the non-contaminated portion of the facilities.
The DECON and SAFSTOR alternatives were both examined and are presented in the (TLG) Decommissioning Cost Analysis section (Section 11) of this filing. The ENTOMB alternative was not considered, because it is considered impractical for a facility which generates significant amounts of long-lived radioactive material due to neutron activation.
FPL selected an integrated DECON decommissioning option for St. Lucie Units 1 and 2.
Due to the difference in the operating license period of Units 1 and 2, this option entails approximately 7 years of dormancy (SAFSTOR) for Unit 1 followed by prompt

Florida Power & Light Company 2010 Decommissioning Study St. Lucie Nuclear Units Assumptions Page 3 of 11 dismantlement (DECON) of both Units 1 and 2. The integrated DECON method provides not only a lower cost, but also enables a sequence of events, which allows for a one-time mobilization of contractor personnel and equipment. This method is consistent with the method in prior studies approved by the Commission for purposes of determining the appropriate accrual and funding requirements.
Total Decommissioning Costs Below are the total estimated costs of Decommissioning the St. Lucie facility as provided by FPL's consultant, TLG Services, Inc. in 2010 dollars.
St. Lucie Unit No. 1 Labor                $      387,244,000 Equip & Materials           148,038,000 Transportation               21,109,000 Burial                       74,735,000 Other                       135,998,000 Total                      767,124,000 St. Lucie Unit No. 2 Labor                $      385,532,000 Equip & Materials           119,983,000 Transportation                21,918,000 Burial                       85,074,000 Other                        99,123,000 Total                      711,630,000 Funding Method In Docket No. 810100-EU, Order No. 10987 issued July 13, 1982, the FPSC ordered FPL to establish a funded reserve. Beginning in 1983 FPL began making contributions, on a net of tax basis, to an externally funded reserve. In 1986, the Treasury Department issued temporary regulations under Internal Revenue Code Section 468A relating to the deductibility of contributions made to a qualified decommissioning fund. These regulations, which were finalized in March of 1988, provide for an annual election by the taxpayer to make tax-deductible contributions to a qualified nuclear decommissioning fund. Qualified nuclear decommissioning funds have been established by FPL for each of the four nuclear units. FPL elected to make contributions to the qualified funds, to the maximum allowed, for the years 1984 through 1987, 1992 through 2004 and for the year

Florida Power & Light Company 2010 Decommissioning Study St. Lucie Nuclear Units Assumptions Page 4 of 11 to date period ended August 31, 2005. Per the Stipulation and Settlement Agreement approved by the Commission in FPSC Order No. FPSC-05-0902-S-EI, FPL suspended accruals effective September 1, 2005, and as such, no additional contributions to the funds have been made subsequent to that date.
The funding analysis presented in Sections G of this study indicates.that no additional contributions to the qualified and nonqualified funds are projected to be required through the remainder of the funding period that ends with the expiration of the unit's operating license. Only the after-tax earnings of the trust fund investments are assumed to continue to be reinvested and accumulated in the respective funds. Future decommissioning expenditures are assumed to be distributed from the qualified and nonqualified funds in proportion to the balance accumulated at the time of expenditure.
Funding Period The funding period, to the extent funding is required, is that period over which revenues are collected from ratepayers for purposes of decommissioning the St. Lucie Units.
Funding periods for both units end on the last day of the month preceding the month in which the operating license for the unit is due to expire. The operating license expiration dates for the St. Lucie units are as follows.
* St. Lucie Unit No. 1 - March 1, 2036
* St. Lucie Unit No. 2 - April 6, 2043 Based on the results of the funding analysis presented in Support Schedule G, no additional funding is required at this time.
Fund Earnings Rate For purposes of this 2010 study update and funding analysis, the projected annual funds earnings rate, net of taxes and all other administrative costs charged to the trust funds, for Units 1 and 2 qualified and nonqualified fund investments, is assumed to be 3.9%. This assumption is based on a projected real long-term, after tax and net of fees, earnings rate of 1.9% plus an estimated long term average inflation rate of 2.0%. The long-term, after tax and net of fees earnings rate reflects the projection of continued adequacy of the funds and assumes a conservative investment strategy where the funds are moved to 100% fixed income prior to the first year of decommissioning and a more conservative all bonds & cash asset mix in the final years of decommissioning. FPL recognizes that over

Florida Power & iUght Company 2010 Decommissioning Study St. Lucie Nuclear Units Assumptions Page 5 of 11 the long-term period there will likely be periods when the earned return may be greater or less than the assumed 3.9%. Consistent with prior Commission practice and Rule 25-6.04365 (FAC) the assumptions presented in this 2010 study will be reviewed and updated as appropriate "at least once every five years".
The annual rates of change in CPI were taken from "The U. S. Economy, The 30 - Year Focus, Third - Quarter 2010", published by Global Insight.
Escalation Rate The annual escalation rates used to estimate total future dismantlement costs from 2010 through the final year of decommissioning are as follows:
Average Annual Escalation Rate St. Lucie Unit No. 1                              2.84%
St. Lucie Unit No. 2                              2.97%
The above rates were derived by applying separate inflation indices to each of the major cost components of Labor, Materials and Equipment, Transportation, Burial, and Other.
Cost Component                             Inflation Index Labor                               Compensation per Hour Materials and Equip.

For purposes of this 2010 study update, the inflation indices were obtained from The U.S.
Economy, The 30- Year Focus, Third - Quarter 2010", published by Global Insight except for the burial index.

Florida Power & Light Company 2010 Decommissioning Study St. Lucie Nuclear Units Assumptions Page 6 of 11 The burial cost estimates are assumed to escalate at an average annual rate of 3%. This is a reduction from the 6.6% rate assumed in the 2005 study. Since the 2005 study was prepared, FPL has signed an agreement with Energy Solutions which provides for the long-term disposal of Class Awaste generated during decommissioning. As such, burial costs for disposal of Class A waste is estimated based on the Energy Solution agreement.
Escalation of pricing under this agreement is tied to changes in the Consumer Price Index (CPI). In addition, the cost estimates for processed/conditioned (at off-site recycling center) disposal of Class A waste is assumed to be at a competitive rate comparable to the Energy Solutions pricing. Burial cost rates for Class B and Class C waste, not covered by the Energy Solutions Agreement, are less certain and based on rates equivalent to Barnwell published rates. The escalation rate applicable to Class B and C waste is assumed to be 6.6% which approximates the historical rate of change in published Barnwell rates. The resulting annual escalation rate of 3% applied to burial costs is a weighted rate based on Class A waste (approx. 90% of total burial costs) at the estimated long-term CPI rate of 2% and Class B and C waste (approx. 10% of total burial costs) estimated at 6.6%.
For a more detail calculation of the overall weighted average escalation rate and annual rate of change for each component please refer to Support Schedule G ("Inflation and Funding Analysis").
FPL/Participant Ownership Share of Nuclear Units The participants and their ownership interests in the St. Lucie facility are as follows:
St. Lucie            St. Lucie Unit No. 1           Unit No. 2 Florida Power & Light Company             100.0%                85.10449%
Orlando Utilities Commission                 0.0                   6.08951%

Total                               100.0%               100.00000%
For purposes of allocating decommissioning costs between FPL and Participants in the St. Lucie Unit No. 2, an adjustment was made to the ownership percentages to reflect the appropriate Common Facility cost obligation of participants.
This adjustment was necessary because the decommissioning cost study attributes common facility costs to St. Lucie No. 2. Because the Participants contractual obligation

Florida Power & Light Company 2010 Decommissioning Study St. Lucie Nuclear Units Assumptions Page 7 of 11 currently provides that they pay for only their ownership share times one-half of the common facility costs, to apply their ownership share to the total cost of decommissioning Unit No. 2 would overstate the participants' cost obligation. This adjustment to the ownership percentage is reflected in what is termed a "Cost Allocation Factor" and represents the cost obligation of FPL and participants as a percentage of the total costs of decommissioning. The "Cost Allocation Factor" calculation is given in Support Schedule H "Cost Allocation Analysis".
The Cost Allocation Factors for St. Lucie Unit No. 2 are:

See support Schedule C ("Projected Fund and Reserve Balances") for detail composition and adjustments to the qualified and nonqualified fund balances.
End of Life Materials and Supplies Inventory Values The decommissioning cost estimates contained in the TLG Decommissioning Cost Analysis section of this study and in the funding analysis contained in Support Schedule G of this filing do not take into consideration the unrecovered value of any Materials and Supplies Inventories that will ultimately exist at the site following shut down of both units.
Both FPL and this Commission have previously recognized that there will be a level of inventories that will remain at the end of life of Unit No. 2, the last unit to reach end of license, which must be recovered prior to the end of site operations. These inventories are unique and will have little value other than scrap value when the units are decommissioned. In Order No. FPSC-02-0055-PAA-EI, the Commission authorized FPL to begin recording the amortization of estimated end of life materials and supplies costs as a base rate fuel expense with a credit to a separate (unfunded) sub-account of Reserve Account 228. Additionally, the Commission directed the Company to address the costs associated with the materials and supplies in subsequent decommissioning studies so that the related annual accruals can be revised, if warranted. The annual

Florida Power & Light Company 2010 Decommissioning Study St. Lucie Nuclear Units Assumptions Page 9 of 11 expense/reserve accruals associated with End of Life Inventories are being accounted for, as directed by the Commission, in a separate (unfunded) sub-account of Reserve Account 228.
As provided in Support Schedule E of this study, the Materials and Supplies inventory balance, less estimated salvage, that is anticipated to remain at the end of life of Unit No.
2, the last unit to reach end of license, is projected to be $18,977,468 (Net of Participants' obligation). The actual balance accrued as of 12/31/10 is $3,836,711. FPL is not requesting a change in accruals at this time. Rather, FPL believes that the results of these updated values for End of Life Materials and Supplies should be addressed in FPL's next base rate proceeding and the appropriate changes in accruals, if any, be made at that time.
End of Life Last Core Nuclear Fuel Values FPL recognizes that there will be unburned fuel that will remain in the fuel assemblies at the end of the last operating cycle of each nuclear unit when it ceases operation. In Docket No 981246-El the Commission found that the cost associated with the Last Core were costs that should be considered a base rate future obligation and that amortization of this obligation over the remaining life span of each nuclear unit ratably allocates the costs to those customers receiving the benefit of the nuclear generation and avoids a burdensome expense at the time of unit shut down. In Order No. FPSC-002-0055-PAA-EI the Commission authorized FPL to begin recording the amortization of estimated Last Core costs as a base rate fuel expense with a credit to a separate (unfunded) sub-account of Reserve Account 228. Additionally, the Commission directed the Company to address the costs associated with the Last Core in subsequent decommissioning studies so that the related annual accruals can be revised, if warranted. The annual expense/reserve accruals associated with End of Life Nuclear Fuel Last Core values are accounted for, as directed by the Commission, in a separate (unfunded) sub-account of Reserve Account 228.
As provided in Support Schedule F of this study, the estimated cost of unburned fuel remaining in the reactor at the end of life (end of license) for each unit is:
        "   Unit No. 1                                 $87,200,000
* Unit No. 2 (net of Participant's costs)    $93,800,000 The actual balances accrued as of 12/31/10 are:

Florida Power & Light Company 2010 Decommissioning Study St. Lucie Nuclear Units Assumptions Page 10 of 11
* Unit No. 1                                $13,380,623
* Unit No. 2 (net of Participant's costs)   $7,639,819 FPL is not requesting a change in accruals at this time. Rather, FPL. believes that the results of these updated values for End of Life Nuclear Fuel Last Core should be addressed in FPL's next base rate proceeding and the appropriate changes in accruals, if any, be made at that time.
Spent Nuclear Fuel Storage The Nuclear Waste Policy Act of 1982 assigns to the Federal Government responsibility to provide for the permanent disposal of spent nuclear fuel (SNF) and high-level radioactive waste (HLW), and committed the DOE to begin acceptance of SNF/HLW not later than January 31, 1998 under terms of its Standard Disposal Contracts with waste generators.
The DOE has not yet provided for SNF storage and is not accepting SNF as committed to under the contract.
In Docket No. 941350-El, and No. 981246-El, the FPSC recognized the impact on the decommissioning process and the potential costs of on-site dry fuel storage resulting from the inability of the DOE to provide for the timely removal of SNF. In Order Nos. PSC 1531-FOF-EI and PSC-02-0055-PAA-EI, the FPSC specifically approved the inclusion of costs associated with the dry storage of spent nuclear fuel following the end of each units operating license which were considered necessary to accommodate the timely decommissioning of each unit.
Consistent with the Commission's prior findings, this updated 2010 decommissioning study includes the costs relating to the construction, operation, and dismantlement of an on-site independent spent fuel storage installation (ISFSI) that is required to accommodate the timely decommissioning of the St. Lucie units. The potential cost impact of extended spent fuel storage that will exist subsequent to the license expiration of the St.
Lucie nuclear units is presented in (Section 11) the 2010 Decommissioning Cost Analysis for the St. Lucie Plant. The decommissioning cost estimates included in this filing are based on the TLG prepared Decommissioning Cost Analysis for the St. Lucie Plant, Units 1 and 2 dated December, 2010.
In addition, FPL and certain nuclear plant joint owners signed a settlement agreement (spent fuel settlement agreement) with the U.S. Government in 2009 agreeing to dismiss with prejudice lawsuits filed against the U.S. Government seeking damages caused by the

Florida Power & Light Company 2010 Decommissioning Study St. Lucie Nuclear Units Assumptions Page 11 of 11 DOE's failure to dispose of spent nuclear fuel from FPL's nuclear plants. As such, the DOE is expected to make payments to FPL to cover the costs incurred for managing and storing the spent fuel that it would not have incurred but for DOE's delay in performance.
Below are the St. Lucie estimated costs of Decommissioning expected to be recovered from the DOE as provided by FPL's consultant, TLG Services, Inc. in 2010 dollars.
St. Lucie Unit No. 1 Labor                 $       48,413,000 Equip & Materials             74,260,000 Other                          16,138,000 Total                      138,812,000 St. Lucie Unit No. 2 Labor                 $       37,936,000 Equip & Materials             42,135,000 Other                          12,588,000 Total                       92,659,000 Further discussion of the costs and assumptions regarding DOE reimbursement is contained in Section 3.8 of the Decommissioning Cost Analysis for the St. Lucie Plant, Units 1 and 2 dated December, 2010.
Annual Decommissionina Accrual Reauirements FPL's current annual expense accrual requirements for St Lucie Nuclear Plant Decommissioning costs presented in this study support a zero accrual and funding requirement as of 12/31/10. The decommissioning costs estimates, funding analysis, and supporting assumptions presented in this study were prepared in a manner consistent with prior Commission approved studies, methodologies and practices.

==SUMMARY==

This report presents estimates of the cost to decommission the St. Lucie Nuclear Plant, Units 1 and 2 (St. Lucie). The analysis relies upon site-specific, technical information from an evaluation prepared in 2005,[1] updated to reflect current assumptions pertaining to the disposition of the two nuclear units and relevant industry experience in undertaking such projects. The station inventory, the basis for the decontamination and dismantling requirements and cost, and the decommissioning waste streams, were reviewed for this analysis. The current estimates reflect any substantive changes over the five year period to the configuration of the plant or site that would impact decommissioning.
The current estimates are designed to provide Florida Power & Light Company (FPL) with sufficient information to assess its financial obligations, as they pertain to the decommissioning of the nuclear station. The estimates do not reflect the actual plan to decommission all aspects of St. Lucie; the plan may differ from the assumptions made in the cost estimates based on facts that exist at the time of the decommissioning activity.
The primary goal of the decommissioning is the removal and disposal of the contaminated systems and structures so that the operating licenses for the nuclear units can be terminated. The analysis recognizes that spent fuel will be stored at the site in the wet storage pools and/or in an independent spent fuel storage installation (ISFSI) until such time that it can be transferred to the U.S. Department of Energy (DOE). Consequently, the estimates also include those costs to manage and subsequently decommission these interim storage facilities.
The currently projected cost to promptly decommission the station (DECON alternative), manage the spent fuel, and restore the site, is estimated at $1,478.8 million, as reported in 2010 dollars. The cost to defer decommissioning by placing the unit in safe-storage (SAFSTOR alternative) for approximately 50 years is estimated at $1,725.6 million, as reported in 2010 dollars. A portion of the costs associated with spent fuel management is considered to be recoverable from the DOE, as described later in this section and in more detail in Section 3..
The estimates are based on numerous fundamental assumptions, including regulatory requirements, low-level radioactive waste disposal practices, high-level radioactive waste management options, project contingencies, and site restoration requirements. The estimates incorporate a minimum cooling period for the spent 1   "Decommissioning Cost Analysis for the St. Lucie Nuclear Plant, Units 1 and 2," Document F02-1512-002, Rev. 0, TLG Services, Inc., October 2005 TLG Services, Inc.

Once sufficiently cooled the spent fuel is transferred to the DOE or to the ISFSI for interim storage. The prompt decommissioning scenario assumes that the dismantling of Unit 1 will be delayed so as to sequence decommissioning operations with the Unit 2 (there is a seven year offset in plant shutdown dates). The estimates also include the dismantling of site structures and non-essential facilities and the limited restoration of the site.
Alternatives and Regulations The ultimate objective of the decommissioning process is to reduce the inventory of contaminated and activated material so that the license can be terminated. The Nuclear Regulatory           Commission (NRC) provided initial decommissioning requirements in its rule adopted on June 27, 1988.[2] In this rule, the NRC set forth financial criteria for decommissioning licensed nuclear power facilities. The regulations addressed planning needs, timing, funding methods, and environmental review requirements for decommissioning. The rule also defined three decommissioning alternatives as being acceptable to the NRC: DECON, SAFSTOR, and ENTOMB.
DECON is defined as "the alternative in which the equipment, structures, and portions of a facility and site containing radioactive contaminants are removed or decontaminated to a level that permits the property to be released for unrestricted use shortly after cessation of operations." [3]
SAFSTOR is defined as "the alternative in which the nuclear facility is placed and maintained in a condition that allows the nuclear facility to be safely     stored      and       subsequently          decontaminated          (deferred decontamination) to levels that permit release for unrestricted use."[4]
Decommissioning is to be completed within 60 years, although longer time periods will be considered when necessary to protect public health and safety.
ENTOMB is defined as "the alternative in which radioactive contaminants are encased in a structurally long-lived material, such as concrete; the entombed structure is appropriately maintained and continued surveillance is carried out until the radioactive material 2   U.S. Code of Federal Regulations, Title 10, Parts 30, 40, 50, 51, 70 and 72 "General Requirements for Decommissioning Nuclear Facilities," Nuclear Regulatory Commission, Federal Register Volume 53, Number 123 (p 24018 et seq.), June 27, 1988 3   Ibid.

The 60-year restriction has limited the practicality for the ENTOMB alternative at commercial reactors that generate significant amounts of long-lived radioactive material. In 1997, the NRC directed its staff to re-evaluate this alternative and identify the technical requirements and regulatory actions that would be necessary for entombment to become a viable     option. The       resulting        evaluation      provided      several recommendations; however, rulemaking has been deferred pending the completion of additional research studies, for example, on engineered barriers.
In 1996, the NRC published revisions to the general requirements for decommissioning nuclear power plants to clarify ambiguities and codify procedures and terminology as a means of enhancing efficiency and uniformity in the decommissioning process.[6 ] The amendments allow for greater public participation and better define the transition process from operations to decommissioning.
Regulatory Guide 1.184, issued in July 2000, further described the methods and procedures acceptable to the NRC staff for implementing the requirements of the 1996 revised rule relating to the initial activities and major phases of the decommissioning process. The costs and schedules presented in this analysis follow the general guidance and processes described in the amended regulations. The format and content of the estimates is also consistent with the recommendations of Regulatory Guide 1.202, issued in February 2005.[7]
St. Lucie Decommissioning Scenarios Two decommissioning scenarios were evaluated for the St. Lucie nuclear units. In both instances a 60-year operating life was assumed. The scenarios selected are representative of alternatives available to the owner and are defined as follows:
: 1.      DECON: The operating licenses for Units 1 and 2 currently expire in March 2036 and April 2043, respectively. The first scenario assumes that decommissioning activities at the two units are sequenced and integrated so as to minimize the total duration of the physical dismantling processes. As 5   Ibid.

Decontamination and dismantling activities at Unit 1 begin shortly after decommissioning operations commence at Unit 2 and follow a similar dismantling sequence. Any residual spent fuel is transferred to the ISFSI so as to facilitate decontamination and dismantling activities within the fuel handling buildings. Spent fuel storage operations continue at the site until the transfer of the fuel to the DOE is complete, assumed to be in the year 2073.
: 2.       SAFSTOR: The units are placed into safe-storage shortly after the permanent cessation of operations and defueling. Spent fuel remaining in the spent fuel storage pools after a minimum cooling period is transferred to the ISFSI for interim storage, consistent with the DECON spent fuel management plan.
Decommissioning is deferred beyond the fuel storage period to the maximum extent possible; termination of the licenses would conclude within the required 60-year period. As with the DECON scenario, decommissioning activities at the two units are sequenced and integrated so as to minimize the total duration of the physical dismantling processes.
Methodology The methodology used to develop the estimates described within this document follows the basic approach originally presented in the cost estimating guidelines[8 ] developed by the Atomic Industrial Forum (now Nuclear Energy Institute). This reference describes a unit factor method for determining decommissioning activity costs. The unit factors used in this analysis incorporate site-specific costs and the latest available information on worker productivity in decommissioning.
The estimates also reflect lessons learned from TLG's involvement in the Shippingport Station decommissioning, completed in 1989, and the decommissioning of the Cintichem reactor, hot cells and associated facilities, completed in 1997. In addition, the planning and engineering for the Pathfinder, Shoreham, Rancho Seco, Trojan, Yankee Rowe, Big Rock Point, Maine Yankee, Humboldt Bay-3, Connecticut Yankee and San Onofre-1 nuclear units have provided additional insight into the process, the regulatory aspects, and technical challenges of decommissioning commercial nuclear units.
An activity duration critical path is used to determine the total decommissioning program schedule. The schedule is relied upon in calculating the carrying costs, which 8   T.S.

Contingency Consistent with cost estimating practice, contingencies are applied to the decontamination and dismantling costs developed as "specific provision for
.unforeseeable elements of cost within the defined project scope, particularly important where previous experience relating estimates and actual costs has shown that unforeseeable events which will increase costs are likely to occur."[ 9] The cost elements in the estimates are based on ideal conditions; therefore, the types of unforeseeable events that are almost certain to occur in decommissioning, based on industry experience, are addressed through a percentage contingency applied on a line-item basis. This contingency factor is a nearly universal element in all large-scale construction and demolition projects. It should be noted that contingency, as used in this analysis, does not account for price escalation and inflation in the cost of decommissioning over the remaining operating life of the nuclear units.
Contingency funds are expected to be fully expended throughout the program. As such, inclusion of contingency is necessary to provide assurance that sufficient funding will be available to accomplish the intended tasks.
Low-Level Radioactive Waste Disposal The contaminated and activated material generated in the decontamination and dismantling of a commercial nuclear reactor is classified as low-level (radioactive) waste, although not all of the material is suitable for "shallow-land" disposal. With the passage of the "Low-Level Radioactive Waste Policy Act" in 1980,[101 and its Amendments of 1985,[11] the states became ultimately responsible for the disposition of low-level radioactive waste generated within their own borders. However, with the exception of Texas (which has issued a license for a new facility), no new compact facilities have been successfully sited, licensed, and constructed.
In past studies, there were two facilities available to FPL for the disposal of low-level radioactive waste generated by St. Lucie. As of July 1, 2008, however, the facility in Barnwell, South Carolina was closed to generators outside the Atlantic Compact (comprised of the states of Connecticut, New Jersey and South Carolina). This leaves the facility in Clive, Utah, operated by EnergySolutions, as the only currently available destination for low-level radioactive waste requiring controlled disposal, until 9   Project and Cost Engineers' Handbook, Second Edition, American Association of Cost Engineers, Marcel Dekker, Inc., New York, New York, p. 239 10  "Low-Level Radioactive Waste Policy Act of 1980," Public Law 96-573, 1980 11  "Low-Level Radioactive Waste Policy Amendments Act of 1985," Public Law 99-240, 1986 TLG Services, Inc.

For the purpose of this analysis, the EnergySolutions' facility is used as the basis for estimating the disposal cost for the majority of the radioactive waste (Class A [121).
EnergySolutions does not have a license to dispose of the more highly radioactive waste (Classes B and C), for example, generated in the dismantling of the reactor vessel. As a proxy, the disposal cost for this material is based upon the last published rate schedule for non-compact waste for the Barnwell facility, adjusted for escalation of the Atlantic Compact rates.
The dismantling of the components residing closest to the reactor core generates radioactive waste that may be considered unsuitable for shallow-land disposal (i.e.,
low-level radioactive waste with concentrations of radionuclides that exceed the limits established by the NRC for Class C radioactive waste (GTCC)). The Low-Level Radioactive Waste Policy Amendments Act of 1985 assigned the federal government the responsibility for the disposal of this material. The Act also stated that the beneficiaries of the activities resulting in the generation of such radioactive waste bear all reasonable costs of disposing of such waste. However, to date, the federal government has not identified a cost for disposing of GTCC or a schedule for acceptance. For purposes of this estimate, the GTCC radioactive waste has been assumed to be packaged and disposed of as high-level waste, at a cost equivalent to that envisioned for the spent fuel.
For purposes of this analysis, GTCC is packaged in the same canisters that are designated for the disposal of spent fuel (modified for the different waste form). The GTCC material is stored with the spent fuel at the ISFSI in the DECON scenario and shipped at the conclusion of the spent fuel transfer process. GTCC is shipped as it is generated in the SAFSTOR scenario since it occurs after the fuel has been removed from the site.
A significant portion of the waste material generated during decommissioning may only be potentially contaminated by radioactive materials. This waste can be analyzed on site or shipped off site to licensed facilities for further analysis, for processing andlor for conditioning/recovery. Reduction in the volume of low-level radioactive waste requiring disposal in a licensed low-level radioactive waste disposal facility can be accomplished through a variety of methods, including analyses and surveys or decontamination, to eliminate the portion of waste that does not require disposal as radioactive waste, compaction, incineration or metal melt. The estimates for St. Lucie reflect the savings from waste recovery/volume reduction.

St. Lucie Nuclear Plant, Units I and 2                                 Document F02-1630-001, Rev. 0 DecommissioningCost Analysis                                                         Page xiii of xviii High-Level Radioactive Waste Management Congress passed the "Nuclear Waste Policy Act"[13] (NWPA) in 1982, assigning the federal government's long-standing responsibility for disposal of the spent nuclear fuel and high level radioactive waste created by the commercial nuclear generating plants to the DOE. The NWPA provided that DOE would enter into contracts with utilities in which DOE would promise to take the utilities' spent fuel and high-level radioactive waste and utilities would pay the cost of the disposition services for that material. The NWPA, along with the individual contracts with the utilities, specified that the DOE was to begin accepting spent fuel by January 31, 1998.
Since the original legislation, the DOE has announced several delays in the program schedule. By January 1998, the DOE had failed to accept any spent fuel or high level waste, as required by the NWPA and utility contracts. Delays continue and, as a result, generators have initiated legal action against the DOE in an attempt to obtain compensation for DOE's breach of contract.
A federal appeals court has ruled that DOE's obligation to take possession of spent nuclear fuel is unconditional and cannot be excused either by the absence of a repository or by a claim of unavoidable delay. FPL filed a lawsuit in 2004 claiming damages for DOE's failure to perform as originally prescribed in the standard disposal contract.
On March 31, 2009, FPL executed a Settlement Agreement with the DOE and the Department of Justice (DoJ). In the Agreement, FPL settled the lawsuit in exchange for payments. The payments are intended to cover those costs incurred for managing and storing the spent fuel that it would not have incurred but for DOE's delay in performance.
While the DOE is responsible for the costs incurred until it fulfills its obligation, certain assumptions are needed to assess the financial impact on the identified decommissioning cost scenarios. The assumptions and methodology employed to quantify the expected level of compensation are outlined in Section 3.8.
It is generally necessary that spent fuel be cooled and stored for a minimum period at the generating site prior to transfer. As such, the NRC requires that licensees establish a program to manage and provide funding for the management of all irradiated fuel at the reactor site until title of the fuel is transferred to the Secretary of Energy, pursuant to 10 CFR Part 50.54(bb).[l 41 This funding requirement is fulfilled 13  "Nuclear Waste Policy Act of 1982 and Amendments," DOE's Office of Civilian Radioactive Management, 1982 14 U.S. Code of Federal Regulations, Title 10, Part 50, "Domestic Licensing of Production and Utilization Facilities," Subpart 54 (bb), "Conditions of Licenses" TLG Services, Inc.

The spent fuel pools are expected to contain freshly discharged assemblies (from the most recent refueling cycles) as well as the final reactor core at shutdown. Over the following five and one half years the assemblies are packaged into DOE-provided multi-purpose canisters (MPCs) for transfer to the DOE or dry shielded canisters (DSCs) to the ISFSI for interim storage. It is assumed that this period provides the necessary cooling for the final core to meet the transport and/or storage requirements for decay heat.
DOE's contracts with utilities order the acceptance of spent fuel from utilities based upon the oldest fuel receiving the highest priority.[15] However, DOE contracts provide mechanisms for altering the oldest fuel first allocation scheme, including emergency deliveries, exchanges of allocations amongst utilities and the option of providing priority acceptance from permanently shutdown nuclear reactors.
Because it is unclear how these mechanisms may operate once DOE begins accepting spent fuel from commercial reactors, this study conservatively assumes that DOE will accept spent fuel in an oldest fuel first order. For purposes of this analysis, the first assemblies removed from the St. Lucie site are conservatively assumed to be in 2032. With an estimated, maximum rate of transfer of 3,000 metric tons of uranium (MTU)/year, completion of the removal of fuel from the site is conservatively projected to be in the year 2073. Consequently, costs are included within the estimates for the long-term caretaking of the spent fuel at the St. Lucie site until the year 2073.
FPL's position is that the DOE has a contractual obligation to accept St. Lucie's fuel far earlier than the projections set out above consistent with its contract commitments. No assumption made in this study should be interpreted to be inconsistent with this claim. However, at this time, including the cost of storing spent fuel in this study is the most reasonable approach because it insures the availability of sufficient decommissioning funds at the end of the station's life if, contrary to its contractual obligation, the DOE has not performed earlier.
An ISFSI, which is operated under a general (10 CFR Part 50) license, has been constructed to support management of the spent fuel at the site until the DOE is-able to complete the transfer to a federal repository. It is assumed that the ISFSI will be expanded subsequent to plant shutdown to support decommissioning operations. As 15  DOE's acceptance priority ranking is based on the date that spent nuclear fuel was permanently discharged, with the oldest spent nuclear fuel, on an industry-wide basis, given the higher priority. However, the generator has the right to determine which spent nuclear fuel is delivered, provided that it is in compliance with the Standard Contract.

This will allow decommissioning to continue on the nuclear units.
Site Restoration The efficient removal of the contaminated materials at the site may result in damage to many of the site structures. Blasting, coring, drilling, and the other decontamination activities will substantially damage power block structures, potentially weakening the footings and structural supports. Prompt dismantling of site structures (once the facilities are decontaminated) is clearly the most appropriate and cost-effective option. It is unreasonable to anticipate that these structures would be repaired and preserved after the radiological contamination is removed. The cost to dismantle site structures with a work force already mobilized on site is more efficient than if the process is deferred. Site facilities quickly degrade without maintenance, adding additional expense and creating potential hazards to the public and the demolition work force. Consequently, this study assumes that site structures are removed to a nominal depth of three feet below the local grade level wherever possible. The site is then to be graded and stabilized.
Summary The cost to decommission St. Lucie assumes the removal of all contaminated and activated plant components and structural materials such that the owner may then have unrestricted use of the site with no further requirements for an operating license.
Low-level radioactive waste, other than GTCC waste, is sent to a commercial processor for treatment/conditioning or to a controlled disposal facility.
Decommissioning is accomplished within the 60-year period required by current NRC regulations. In the interim, the spent fuel remains in storage at the site until such time that the transfer to a DOE facility is complete. Once emptied, the fuel storage facilities can be decommissioned (DECON alternative) or placed in storage and decommissioned with the reactor complex (SAFSTOR alternative).
The decommissioning scenarios are described in Section 2. The assumptions are presented in Section 3, along with schedules of annual expenditures. The major cost contributors are identified in Section 6, with detailed activity costs, waste volumes, and associated manpower requirements delineated in Appendices C and D for the DECON and SAFSTOR alternatives. The major cost components are also identified in the cost summary provided at the end of this section.
The cost elements in the estimates are assigned to one of three subcategories: NRC License Termination, Spent Fuel Management, and Site Restoration. The subcategory TLG Services, Inc.

10 CFR Part 50.75). The cost reported for this subcategory is generally sufficient to terminate the operating licenses for the two reactors, recognizing that there may be some additional cost impact from spent fuel management.
The "Spent Fuel Management" subcategory contains costs anticipated to be incurred once the nuclear units cease operation for the off-loading of the pools either directly to the DOE or to the ISFSI for interim storage, and the eventual transfer of fuel from the ISFSI to the DOE. Costs are also included for the operation of the ISFSI until such time that the transfer of all fuel from this facility to an off-site location (e.g., geologic repository or interim facility) is complete. Under the terms of the settlement agreement with the DOE, there are activities and costs identified in the decommissioning cost study that are expected to be eligible for reimbursement (depending upon the timing of the activities). The activities are identified in Section 3.8 and the costs in Tables 3.7 through 3.9.
"Site Restoration" is used to capture costs associated with the dismantling and demolition of buildings and facilities demonstrated to be free from contamination. This includes structures never exposed to radioactive materials, as well as those facilities that have been decontaminated to appropriate levels. Structures are removed to a depth of three feet and backfilled to conform to local grade.
It should be noted that the costs assigned to these subcategories are allocations.
Delegation of cost elements is for the purposes of comparison (e.g., with NRC financial guidelines) or to permit specific financial treatment (e.g., ARO determinations). In reality, there can be considerable interaction between the activities in the three subcategories. For example, an owner may decide to remove non-contaminated structures early in the project to improve access to highly contaminated facilities or plant components. In these instances, the non-contaminated removal costs could be reassigned from Site Restoration to an NRC License Termination support activity.
However, in general, the allocations represent a reasonable accounting of those costs that can be expected to be incurred for the specific subcomponents of the total estimated program cost, if executed as described.
As noted within this document, the estimates were developed and costs are presented in 2010 dollars. As such, the estimates do not reflect the escalation of costs (due to inflationary and market forces) over the remaining operating life of the station or during the decommissioning period.

: 1. INTRODUCTION This report presents estimates of the costs to decommission the St. Lucie Nuclear Plant, Units 1 and 2, (St. Lucie), assuming a 60-year operating life for the selected decommissioning alternatives. The analysis relies upon site-specific, technical information from an earlier evaluation prepared in 2005,[1]* updated to reflect current assumptions pertaining to the disposition of the nuclear station and relevant industry experience in undertaking such projects. The station inventory, the basis for the decontamination and dismantling requirements and cost, and the decommissioning waste streams, were reviewed for this analysis. The current estimates reflect any substantive changes over the five year period to the configuration of the plant or site that would impact decommissioning.
The current estimates are designed to provide Florida Power & Light Company (FPL) with sufficient information to assess their financial obligations, as they pertain to the decommissioning of the nuclear station. It is not a detailed engineering document, but a financial analysis prepared in advance of the detailed engineering that will be required to carry out the decommissioning activity.
1.1   OBJECTIVES OF STUDY The objectives of this analysis are to present comprehensive estimates of the costs to decommission St. Lucie, to provide a sequence or schedule for the associated activities, and to identify the waste streams expected from the decontamination and dismantling activities.
For the purposes of this study, the cessation of operations is assumed to be on March 1, 2036 and April 6, 2043 for Units 1 and 2, respectively, based upon the full term of the current operating licenses.
1.2 SITE DESCRIPTION The St. Lucie site is located approximately halfway between the cities of Fort Pierce and Stuart on the east coast of Florida. Units 1 and 2 are essentially identical pressurized water reactors with supporting facilities (Figure 1.1, Site Photo). FPL is the primary owner and operator of the station. The nuclear units were designed and constructed by Ebasco Services, Inc.
The nuclear steam supply systems (NSSS) were designed by Combustion Engineering. The reactor coolant systems (RCS) consist of two similar heat

Each loop contains two reactor coolant pumps, one steam generator, and associated piping and valves. In addition, the systems include a pressurizer, a pressurizer relief tank, interconnecting piping, and instrumentation necessary for operational control. All the system equipment, except for the digital pressure indicator, three wide range pressure transmitters, and the containment isolation and process actuated valves located in the lines connected to the pressurizer relief tank, are located in the containment buildings.
The containments are a dual containment design comprised of a steel containment vessel surrounded by an annular space and enclosed by reinforced concrete shield buildings. The vessel is cylindrical in shape with a hemispherical dome and ellipsoidal bottom.

The function of the turbine generators, which serve no safety function, is to receive steam from steam generators, economically convert a portion of the thermal energy contained in the steam to electrical energy, and provide extraction steam for five stages of feedwater heating. Steam is directed from the high pressure turbine element to four combination moisture-separator/reheater assemblies before entering the low pressure turbines. The exhaust steam from the two low pressure turbines is condensed in the condenser. With the completion of the extended power uprate activities (described below), Units 1 and 2 will have a maximum potential cold winter capability of 1,052 megawatt-electric (MWe) gross and 1,072 MW gross, respectively.
Heat rejected in the main condensers is removed by the circulating water systems, which condenses the steam exhaust from the turbine. Cooling water for the condenser is supplied by the Atlantic Ocean.
Modifications are underway to increase the power output for each unit. The Extended Power Uprate (EPU) will be a 12-percent uprate. The original licensed core rated thermal power level was 2,560 megawatts-thermal (MWt),
and after a 5.5-percent stretch power uprate in 1981, the current licensed thermal power rating is 2,700 MWt. The uprate licensed thermal power would then be 3,020 MWt. The modifications necessary to support the power uprate will be implemented during the 2010, 2011 and 2012 refueling outages. The impact of the EPU (e.g., from increased neutron fluence), although not significant in decommissioning, is considered in this analysis.
1.3   REGULATORY GUIDANCE The Nuclear Regulatory Commission (NRC) provided initial decommissioning requirements in its rule "General Requirements for Decommissioning Nuclear Facilities," issued in June 1988.[21 This rule set forth financial criteria for decommissioning licensed nuclear power facilities. The regulation addressed decommissioning planning needs, timing, funding methods, and environmental review requirements. The intent of the rule was to ensure ,that decommissioning would be accomplished in a safe and timely manner and that adequate funds would be available for this purpose. Subsequent to the rule, the NRC issued Regulatory Guide 1.159, "Assuring the Availability of Funds for Decommissioning Nuclear Reactors,"[ 3] which provided additional guidance to the licensees of nuclear facilities on the financial methods acceptable to the NRC staff for complying with the requirements of the rule. The regulatory guide addressed the funding requirements and provided guidance on the content and form of the financial assurance mechanisms indicated in the rule.

St. Lucie Nuclear Plant, Units 1 and 2                       Document F02-1630-001, Rev. 0 Decommissioning Cost Analysis                                       Section 1, Page 4 of 10 The rule defined three decommissioning alternatives as being acceptable to the NRC: DECON, SAFSTOR, and ENTOMB. The DECON alternative assumes that any contaminated or activated portion of the plant's systems, structures and facilities are removed or decontaminated to levels that permit the site to be released for unrestricted use shortly after the cessation of plant operations.
The rule also placed limits on the time allowed to complete the decommissioning process. For SAFSTOR, the process is restricted in overall duration to 60 years, unless it can be shown that a longer duration is necessary to protect public health and safety. The guidelines for ENTOMB are similar, providing the NRC with both sufficient leverage and flexibility to ensure that these deferred options are only used in situations where it is reasonable and consistent with the definition of decommissioning. At the conclusion of a 60-year dormancy period (or longer for ENTOMB if the NRC approves such a case), the site would still require significant remediation to meet the unrestricted release limits for license termination.
The ENTOMB alternative has not been viewed as a viable option for power reactors due to the significant time required to isolate the long-lived radionuclides for decay to permissible levels. However, with rulemaking permitting the controlled release of a site,[4] the NRC has re-evaluated this alternative. The resulting feasibility study, based upon an assessment by Pacific Northwest National Laboratory, concluded that the method did have conditional merit for some, if not most reactors. However, the staff also found that additional rulemaking would be needed before this option could be treated as a generic alternative. The NRC had considered rulemaking to alter the 60-year time for completing decommissioning and to clarify the use of engineered barriers for reactor entombments.[5]
The NRC's staff has recommended that rulemaking be deferred, based upon several factors, e.g., no licensee has committed to pursuing the option, disposition of certain waste forms, effectiveness of engineering barriers, and the NRC's current priorities, at least until after the additional research studies are complete. The NRC concurred with the staffs recommendation.
In 1996, the NRC published revisions to the general requirements for decommissioning nuclear power plants.[61 When the decommissioning regulations were adopted in 1988, it was assumed that the majority of licensees would operate for their full licensed life. However, shortly after the regulations were enacted, several licensees permanently and prematurely ceased operations. Exemptions from certain operating requirements were required once the reactor was defueled to facilitate the decommissioning. Each case was handled individually, without clearly defined generic requirements.
The NRC amended the decommissioning regulations in 1996 to clarify TLG Services, Inc.

The amendments allow for greater public participation and better define the transition process from operations to decommissioning.
Under the revised regulations, licensees will submit written certification to the NRC within 30 days after the decision to cease operations. Certification will also be required once the fuel is permanently removed from the reactor vessel.
Submittal of these notices will entitle the licensee to a fee reduction and eliminate the obligation to follow certain requirements needed only during operation of the reactor. Within two years of submitting notice of permanent cessation of operations, the licensee is required to submit a Post-Shutdown Decommissioning Activities Report (PSDAR) to the NRC. The PSDAR describes the planned decommissioning activities, the associated sequence and schedule, and an estimate of expected costs. Prior to completing decommissioning, the licensee is required to submit an application to the NRC to terminate the license, which will include a license termination plan (LTP).
1.3.1 Nuclear Waste Policy Act Congress passed the "Nuclear Waste Policy Act"[7] (NWPA) in 1982, assigning the federal government's long-standing responsibility for disposal of the spent nuclear fuel and high level radioactive waste created by the commercial nuclear generating plants to the DOE. The NWPA provided that DOE would enter into contracts with utilities in which DOE would promise to take the utilities' spent fuel and high-level radioactive waste and utilities would pay the cost of the disposition services for that material. The NWPA, along with the individual contracts with the utilities, specified that the DOE was to begin accepting spent fuel by January 31, 1998.
Since the original legislation, the DOE has announced several delays in the program schedule. By January 1998, the DOE had failed to accept any spent fuel or high level waste, as required by the NWPA and utility contracts. Delays continue and, as a result, generators have initiated legal action against the DOE in an attempt to obtain compensation for DOE's breach of contract.
A federal appeals court has ruled that DOE's obligation to take possession of spent nuclear fuel is unconditional and cannot be excused either by the absence of a repository or by a claim of unavoidable delay.
FPL filed a lawsuit in 2004 claiming damages for DOE's failure to perform as originally prescribed in the standard disposal contract.

In the Agreement, FPL settled the lawsuit in exchange for payments. The payments are intended to cover those costs incurred for managing and storing the spent fuel that it would not have incurred but for DOE's delay in performance.
While the DOE is responsible for the costs incurred until it fulfills its obligation, certain assumptions are needed to assess the financial impact on the identified decommissioning cost scenarios. The assumptions and methodology employed to quantify the expected level of compensation are outlined in Section 3.8.
It is generally necessary that spent fuel be cooled and stored for a minimum period at the generating site prior to transfer. As such, the NRC requires that licensees establish a program to manage and provide funding for the management of all irradiated fuel at the reactor site until title of the fuel is transferred to the Secretary of Energy, pursuant to 10 CFR Part 50.54(bb).[8] This funding requirement is fulfilled through inclusion of certain cost elements in the decommissioning estimates, for example, expansion and operation of the Independent Spent Fuel Storage Facility (ISFSI) subsequent to plant shutdown, and continued operation of the spent fuel pools.
The spent fuel pools are expected to contain freshly discharged assemblies (from the most recent refueling cycles) as well as the final reactor core at shutdown. Over the following five and one half years the assemblies are packaged into DOE-provided multi-purpose canisters (MPCs) for transfer to the DOE or in dry-shielded canisters (DSCs) for interim storage at the ISFSI. It is assumed that this period provides the necessary cooling for the final core to meet the transport and/or storage requirements for decay heat.
DOE's contracts with utilities order the acceptance of spent fuel from utilities based upon the oldest fuel receiving the highest priority. [While DOE's acceptance priority ranking is based on the date that spent nuclear fuel was permanently discharged, with the oldest spent nuclear fuel, on an industry-wide basis, given the higher priority, the generator has the right to determine which spent nuclear fuel is delivered, provided that it is in compliance with the Standard Contract. DOE contracts also provide mechanisms for altering the oldest fuel first allocation scheme, including emergency deliveries, exchanges of allocations amongst utilities and the option of providing priority TLG Services, Inc.

St. Lucie Nuclear Plant, Units I and 2                      Document F02-1630-001, Rev. 0 Decommissioning Cost Analysis                                       Section 1, Page 7 of 10 acceptance from permanently shutdown nuclear reactors.] Because it is unclear how these mechanisms may operate once DOE begins accepting spent fuel from commercial reactors, this study conservatively assumes that DOE will accept spent fuel in an oldest fuel first order. For purposes of this analysis, the first assemblies removed from the St.
Lucie site are conservatively assumed to be in 2032. With an estimated, maximum rate of transfer of 3,000 metric tons of uranium (MTU)/year, completion of the removal of fuel from the site is conservatively projected to be in the year 2073. Consequently, costs are included within the estimates for the long-term caretaking of the spent fuel at the St.
Lucie site until the year 2073.
FPL's position is that the DOE has a contractual obligation to accept St.
Lucie's fuel far earlier than the projections set out above consistent with its contract commitments. No assumption made in this study should be interpreted to be inconsistent with this claim. However, at this time, including the cost of storing spent fuel in this study is the most reasonable approach because it insures the availability of sufficient decommissioning funds at the end of the station's life if, contrary to its contractual obligation, the DOE has not performed earlier.
An ISFSI, which is operated under a general (10 CFR Part 50) license, has been constructed to support management of the spent fuel at the site until the DOE is able to complete the transfer to a federal repository. It is assumed that the ISFSI will be expanded subsequent to plant shutdown to support decommissioning operations. As such, the fuel that cannot be transferred directly to the DOE from the wet pools is packaged for interim storage at the ISFSI. This will allow decommissioning to continue on the nuclear units.
1.3.2 Low-Level Radioactive Waste Acts The contaminated and activated material generated in the decontamination and dismantling of a commercial nuclear reactor is classified as low-level (radioactive) waste, although not all of the material is suitable for "shallow-land" disposal. With the passage of the "Low-Level Radioactive Waste Policy Act" in 1980,[91 and its Amendments of 1985,[110 the states became ultimately responsible for the disposition of low-level radioactive waste generated within their own borders. However, with the exception of Texas (which has issued a license for a new facility), no new compact facilities have been successfully sited, licensed, and constructed.

St. Lucie NuclearPlant, Units I and 2                       Document F02-1630-001, Rev. 0 DecommissioningCost Analysis                                        Section 1, Page 8 of 10 In past studies, there were two facilities available to FPL for the disposal of low-level radioactive waste generated by St. Lucie. As of July 1, 2008, however, the facility in Barnwell, South Carolina was closed to generators outside the Atlantic Compact (comprised of the states of Connecticut, New Jersey and South Carolina). This leaves the facility in Clive, Utah, operated by EnergySolutions, as the only currently available destination for low-level radioactive waste requiring controlled disposal, until the construction of Waste Control Specialist's facility in Andrews County, Texas, is complete.
For the purpose of this analysis, the EnergySolutions' facility is used as the basis for estimating the disposal cost for the majority of the radioactive waste (Class A [11]). EnergySolutions does not have a license to dispose of the more highly radioactive waste (Classes B and C), for example, generated in the dismantling of the reactor vessel. As a proxy, the disposal cost for this material is based upon the last published rate schedule for non-compact waste for the Barnwell facility, adjusted for escalation of the Atlantic Compact rates.
The dismantling of the components residing closest to the reactor core generates radioactive waste that may be considered unsuitable for shallow-land     disposal   (i.e.,  low-level radioactive      waste      with concentrations of radionuclides that exceed the limits established by the NRC for Class C radioactive waste (GTCC)). The Low-Level Radioactive Waste Policy Amendments Act of 1985 assigned the federal government the responsibility for the disposal of this GTCC material. The Act also stated that the beneficiaries of the activities resulting in the generation of such radioactive waste bear all reasonable costs of disposing of such waste. However, to date, the federal government has not identified a cost for disposing of GTCC or a schedule for acceptance. For purposes of this estimate, the GTCC radioactive waste has been assumed to be packaged and disposed of as high-level waste, at a cost equivalent to that envisioned for the spent fuel.
For purposes of this analysis, GTCC is packaged in the same canisters that are designated for the disposal of spent fuel (modified for the different waste form). The GTCC material is stored with the spent fuel at the ISFSI in the DECON scenario and shipped at the conclusion of the spent fuel transfer process. GTCC is shipped as it is generated in the SAFSTOR scenario since it occurs after the fuel has been removed from the site.

This waste can be analyzed on site or shipped off site to licensed facilities for further analysis, for processing and/or for conditioning/recovery. Reduction in the volume of low-level radioactive waste requiring disposal in a licensed low-level radioactive waste disposal facility can be accomplished through a variety of methods, including analyses and surveys or decontamination to eliminate the portion of waste that does not require disposal as radioactive waste, compaction, incineration or metal melt. The estimates for St. Lucie reflect the savings from waste recovery/volume reduction.
1.3.3 Radiological Criteria for License Termination In 1997, the NRC published Subpart E, "Radiological Criteria for License Termination,"[ 12] amending 10 CFR Part 20. This subpart provides radiological criteria for releasing a facility for unrestricted use.
The regulation states that the site can be released for unrestricted use if radioactivity levels are such that the average member of a critical group would not receive a Total Effective Dose Equivalent (TEDE) in excess of 25 millirem per year, and provided that residual radioactivity has been reduced to levels that are As Low As Reasonably Achievable (ALARA).
The decommissioning estimates assume that the St. Lucie site will be remediated to a residual level consistent with the NRC-prescribed level.
It should be noted that the NRC and the Environmental Protection Agency (EPA) differ on the amount of residual radioactivity considered acceptable in site remediation. The EPA has two limits that apply to radioactive materials. An EPA limit of 15 millirem per year is derived from criteria established by the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA or Superfund).[ 13]
An additional and separate limit of 4 millirem per year, as defined in 40 14 CFR &sect; 141.16, is applied to drinking water.[ 1 On October 9, 2002, the NRC signed an agreement with the EPA on the radiological decommissioning and decontamination of NRC-licensed sites. The Memorandum of Understanding (MOU)[151 provides that EPA will defer exercise of authority under CERCLA for the majority of facilities decommissioned under NRC authority. The MOU also includes provisions for NRC and EPA consultation for certain sites when, at the time of license termination, (1) groundwater contamination exceeds EPA-permitted levels; (2) NRC contemplates restricted release of the site; and/or (3) residual radioactive soil concentrations exceed levels defined in the MOU.

Most sites are expected to meet the NRC criteria for unrestricted use, and the NRC believes that only a few sites will have groundwater or soil contamination in excess of the levels specified in the MOU that trigger consultation with the EPA. However, if there are other hazardous materials on the site, the EPA may be involved in the cleanup. As such, the possibility of dual regulation remains for certain licensees. The present study does not include any costs for this occurrence.

: 2. DECOMMISSIONING ALTERNATIVES Detailed cost estimates were developed to decommission St. Lucie based upon the approved decommissioning alternatives: DECON and SAFSTOR. Although the alternatives differ with respect to technique, process, cost, and schedule, they attain the same result: the ultimate release of the site for unrestricted use.
Two decommissioning scenarios were evaluated for the St. Lucie nuclear units. In both instances a 60-year operating life was assumed. The scenarios selected are representative of alternatives available to the owner and are defined as follows:
: 1. DECON: The operating licenses for Units I and 2 currently expire in March 2036 and April 2043, respectively. The first scenario assumes that decommissioning activities at the two units are sequenced and integrated so as to minimize the total duration of the physical dismantling processes. As such, Unit 1 is placed into an abbreviated period of safe-storage until Unit 2 completes its operations.
Decontamination and dismantling activities at Unit 1 begin shortly after decommissioning operations commence at Unit 2 and follow a similar dismantling sequence. Any residual spent fuel is transferred to the ISFSI so as to facilitate decontamination and dismantling activities within the fuel handling buildings.
Spent fuel storage operations continue at the site until the transfer of the fuel to the DOE is complete, assumed to be in the year 2073.
: 2. SAFSTOR: The units are placed into safe-storage shortly after the permanent cessation of operations and defueling. Spent fuel remaining in the spent fuel storage pools after a minimum cooling period is transferred to the ISFSI for interim storage, consistent with the DECON spent fuel management plan.
Decommissioning is deferred beyond the fuel storage period to the maximum extent possible; termination of the licenses would conclude within the required 60-year period. As with the DECON scenario, decommissioning activities at the two units are sequenced and integrated so as to minimize the total duration of the physical dismantling processes.
The following sections describe the basic activities associated with each alternative.
Although detailed procedures for each activity identified are not provided, and the actual sequence of work may vary, the activity descriptions provide a basis not only for estimating but also for the expected scope of work, i.e., engineering and planning at the time of decommissioning.
The conceptual approach that the NRC has described in its regulations divides decommissioning into three phases. The initial phase commences with the effective date of permanent cessation of operations and involves the transition of both plant TLG Services, Inc.

During the first phase, notification is to be provided to the NRC certifying the permanent cessation of operations and the removal of fuel from the reactor vessel. The licensee is then prohibited from reactor operation.
The second phase encompasses activities during the storage period or during major decommissioning activities, or a combination of the two. The third phase pertains to the activities involved in license termination. The decommissioning estimates developed for St. Lucie are also divided into phases or periods; however, demarcation of the phases is based upon major milestones within the project or significant changes in the projected expenditures.
2.1 DECON The DECON alternative, as defined by the NRC, is "the alternative in which the equipment, structures, and portions of a facility and site containing radioactive contaminants are removed or decontaminated to a level that permits the property to be released for unrestricted use shortly after cessation of operations." This study does not address the cost to dispose of the spent fuel residing at the site; such costs are funded through a surcharge on electrical generation. However, the study does estimate the costs incurred with the interim on-site storage of the fuel pending shipment by the DOE to an off-site disposal facility.
2.1.1 Period 1 - Preparations In anticipation of the cessation of plant operations, detailed preparations are undertaken to provide a smooth transition from plant operations to site decommissioning. Through implementation of a staffing transition plan, the organization required to manage the intended decommissioning activities is assembled from available plant staff and outside resources. Preparations include the planning for permanent defueling of the reactor, revision of technical specifications applicable to the operating conditions and requirements, a characterization of the facility and major components, and the development of the PSDAR.
Engineering and Planning The PSDAR, required within two years of the notice to cease operations, provides a description of the licensee's planned decommissioning activities, a timetable, and the associated financial requirements of the intended decommissioning program. Upon receipt of the PSDAR, the TLG Services,Inc.

Ninety days following submittal and NRC receipt of the PSDAR, the licensee may begin to perform major decommissioning activities under a modified 10 CFR &sect;50.59 procedure, i.e., without specific NRC approval. Major activities are defined as any activity that results in permanent removal of major radioactive components, permanently modifies the structure of the containment, or results in dismantling components (for shipment) containing GTCC, as defined by 10 CFR &sect;61. Major components are further defined as comprising the reactor vessel and internals, large bore reactor coolant system piping, steam generators, and other large components that are radioactive. The NRC includes the following additional criteria for use of the &sect;50.59 process in decommissioning. The proposed activity must not:
o   foreclose release of the site for possible unrestricted use, o   significantly increase decommissioning costs, o   cause any significant environmental impact, or o   violate the terms of the licensee's existing license.
Existing operational technical specifications are reviewed and modified to reflect plant conditions and the safety concerns associated with permanent cessation of operations. The environmental impact associated with the planned decommissioning activities is also considered.
Typically, a licensee will not be allowed to proceed if the consequences of a particular decommissioning activity are greater than that bounded by previously evaluated environmental assessments or impact statements.
In this instance, the licensee would have to submit a license amendment for the specific activity and update the environmental report.
The decommissioning program outlined in the PSDAR will be designed to accomplish the required tasks within the ALARA guidelines (as defined in 10 CFR &sect;20) for protection of personnel from exposure to radiation hazards. It will also address the continued protection of the health and safety of the public and the environment during the dismantling activity. Consequently, with the development of the PSDAR, activity specifications, cost-benefit and safety analyses, and work packages and procedures, would be assembled to support the proposed decontamination and dismantling activities.

            " Characterization of the site and surrounding environs. This includes radiation surveys of work areas, major components (including the reactor vessel and its internals), internal piping, and primary shield cores.
o   Isolation of the spent fuel storage pools and fuel handling systems, such that decommissioning operations can commence on the balance of the plant. The pools will remain operational for approximately five and one half years following the cessation of operations before the inventory resident in the core at shutdown can be transferred to the DOE or to the ISFSI for interim storage.
o   Specification of- transport and disposal requirements for activated materials and/or hazardous materials, including shielding and waste stabilization.
o   Development of procedures for occupational exposure control, control and release of liquid and gaseous effluent, processing of radwaste (including dry-active waste, resins, filter media, metallic and non-metallic components generated in decommissioning), site security and emergency programs, and industrial safety.
The DECON cost model for Unit 1 uses the nomenclature of the SAFSTOR alternative to accommodate the seven year offset in unit shutdown dates and the inclusion of a delay in the start of Unit 1 decommissioning. As such, Period 2, for Unit 1, is an abbreviated period of storage, awaiting the cessation of operations at Unit 2. During this period the fuel is offloaded from the Unit 1 storage pool to either the DOE or the ISFSI. Essential systems (to future decommissioning operations) are maintained and operational waste inventories processed during this period. Period 2 is followed by preparations to reactivate the unit for decontamination and dismantling, referred to as Period 3 for purposes of the cost model. The activities in Periods 4 and 5 for Unit 1 are identical to those delineated in Period 2 and Period 3 below with the exception of any defueling activities that have already been performed at Unit 1.

Significant decommissioning activities in this phase include:
            "   Construction of temporary facilities and/or modification of existing facilities to support dismantling activities. This may include a centralized processing area to facilitate equipment removal and component preparations for off-site disposal.
o   Reconfiguration and modification of site structures and facilities as needed to support decommissioning operations. This may include the upgrading of roads (on- and off-site) to facilitate hauling and transport. Modifications may be required to the containment structure to facilitate access of large/heavy equipment. Modifications may also be required to the refueling area of the building to support the segmentation of the reactor vessel internals and component extraction.
            "   Design and fabrication of temporary and permanent shielding to support removal and transportation activities, 'construction of contamination control envelopes, and the procurement of specialty tooling.
o   Procurement (lease or purchase) of shipping canisters, shielded cask liners, and industrial packages.
o   Decontamination of components and piping systems as required to control (minimize) worker exposure.

Segmentation of the reactor vessel. A shielded platform is installed for segmentation as cutting operations are performed in-air using remotely operated equipment within a contamination control envelope. The water level is maintained just below the cut to minimize the working area dose rates. Segments are transferred in-air to containers that are stored under water, for example, in an isolated area of the refueling canal.
0   Removal of the activated portions of the concrete biological shield and accessible contaminated concrete surfaces. If dictated by the steam generator and pressurizer removal scenarios, those portions of the associated cubicles necessary for access and component extraction are removed.
o   Removal of the steam generators and pressurizer for material recovery and controlled disposal. The generators will be moved to an on-site processing center, the steam domes removed and the internal components segregated for recycling. The lower shell and tube bundle will be packaged for direct disposal. These components can serve as their own burial containers provided that all penetrations are properly sealed and the internal contaminants are stabilized, e.g.,
with grout. Steel shielding will be added, as necessary, to those external areas of the package to meet transportation limits and regulations.
At least two years prior to the anticipated date of the completion of the remediation process, an LTP is required. Submitted as a supplement to the Final Safety Analysis Report (FSAR) or its equivalent, the plan must include: a site characterization, description of the remaining dismantling activities, plans for site remediation, procedures for the final radiation survey, designation of the end use of the site, an updated cost estimate to complete the decommissioning, and any associated environmental concerns. The NRC will notice the receipt of the plan, make the plan available for public comment, and schedule a local hearing. LTP approval will be subject to any conditions and limitations as deemed appropriate by the NRC. The licensee may then commence with the final remediation of site facilities and services, including:
o   Removal of remaining plant systems and associated components as they become nonessential to the decommissioning program or worker health and safety (e.g., waste collection and treatment systems, electrical power and ventilation systems).

            "   Removal of the steel liners from refueling canal, disposing of the activated and contaminated sections as radioactive waste. Removal of any activated/ contaminated concrete.
o   Surveys of the decontaminated areas of the containment structure.
o   Remediation and removal of the contaminated equipment and material from the auxiliary and fuel buildings and any other contaminated facility. Radiation and contamination controls will be utilized until residual levels indicate that the structures and equipment can be released for unrestricted access and conventional demolition. This activity may necessitate the dismantling and disposition of most of the systems and components (both clean and contaminated) located within these buildings. This activity facilitates surface decontamination and subsequent verification surveys required prior to obtaining release for demolition.
            "   Routing of material removed in the decontamination and dismantling to a central processing area. Material certified to be free of contamination is released for unrestricted disposition, e.g., as scrap, recycle, or general disposal. Contaminated material is characterized and segregated for additional off-site processing (disassembly, chemical cleaning, volume reduction, and waste treatment), and/or packaged for controlled disposal at a low-level radioactive waste disposal facility.
Incorporated into the LTP is the Final Survey Plan. This plan identifies the radiological surveys to be performed once the decontamination activities are completed and is developed using the guidance provided in the "Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM)."[ 16] This document incorporates the statistical approaches to survey design and data interpretation used by the EPA. It also identifies commercially available instrumentation and procedures for conducting radiological surveys. Use of this guidance ensures that the surveys are conducted in a manner that provides a high degree of confidence that applicable NRC criteria are satisfied. Once the survey is complete, the results are provided to the NRC in a format that can be verified. The NRC then reviews and evaluates the information, performs an independent confirmation of radiological site conditions, and makes a determination on the requested change to the operating license (that would release the property, exclusive of the ISFSI, for unrestricted use).
The NRC will amend the operating license(s) if it determines that site remediation has been performed in accordance with the LTP, and that TLG Services, Inc.

2.1.3 Period 3 - Site Restoration Following completion of decommissioning operations, site restoration activities will begin. Efficient removal of the contaminated materials and verification that residual radionuclide concentrations are below the NRC limits will result in substantial damage to many of the structures.
Although performed in a controlled, safe manner, blasting, coring, drilling, scarification (surface removal), and the other decontamination activities will substantially degrade power block structures including the reactor, auxiliary, radwaste warehouse and fuel buildings. Under certain     circumstances,    verifying   that subsurface      radionuclide concentrations meet NRC site release requirements will require removal of grade slabs and lower floors, potentially weakening footings and structural supports. This removal activity will be necessary for those facilities and plant areas where historical records, when available, indicate the potential for radionuclides having been present in the soil, where system failures have been recorded, or where it is required to confirm that subsurface process and drain lines were not breached over the operating life of the station.
Prompt dismantling of site structures is clearly the most appropriate and cost-effective option. It is unreasonable to anticipate that these structures would be repaired and preserved after the radiological contamination is removed. The cost to dismantle site structures with a work force already mobilized on site is more efficient than if the process were deferred. Site facilities quickly degrade without maintenance, adding additional expense and creating potential hazards to the public as well as to future workers. Abandonment creates a breeding ground for vermin infestation as well as other biological hazards.
This cost study presumes that non-essential structures and site facilities are dismantled as a continuation of the decommissioning activity.
Foundations and exterior walls are removed to a nominal depth of three feet below grade. The three-foot depth allows for the placement of gravel for drainage, as well as topsoil, so that vegetation can be established for erosion control. Site areas affected by the dismantling activities are restored and the plant area graded as required to prevent ponding and inhibit the refloating of subsurface materials.

The processed material is then used on site to backfill foundation voids.
Excess non-contaminated materials are trucked to an off-site area for disposal as construction debris.
2.1.4 ISFSI Operations and Decommissioning The ISFSI will continue to operate under a general license (10 CFR &sect;50) following the amendment of the operating license(s) to release the adjacent property. Assuming the DOE starts accepting fuel from the St.
Lucie spent fuel storage pools in 2032, transfer of spent fuel from the ISFSI is anticipated to begin in 2049, and continue through the year 2073.
At the conclusion of the spent fuel transfer process, the ISFSI will be decommissioned. The NRC will terminate the &sect;50 license when it determines that the remediation of the ISFSI has been performed in accordance with an ISFSI license termination plan and that the final radiation survey and associated documentation demonstrate that the facility is suitable for release. Once the requirements are satisfied, the NRC can terminate the license for the ISFSI.
Spent fuel is stored on the ISFSI in multi-purpose canisters, with a concrete overpack. For purposes of this cost analysis, it is assumed that once the inner canisters containing the spent fuel assemblies have been removed, any required decontamination performed on the storage overpack (some minor activation is assumed), and the license for the facility terminated, the concrete overpacks can be dismantled using conventional techniques for the demolition of reinforced concrete. The concrete storage pad is then removed and the area regraded.
2.2   SAFSTOR The NRC defines SAFSTOR as "the alternative in which the nuclear facility is placed and maintained in a condition that allows the nuclear facility to be safely stored and subsequently decontaminated (deferred decontamination) to, levels that permit release for unrestricted use." The facility is left intact (during the dormancy period), with structures maintained in a sound condition. Systems that are not required to support the spent fuel pools or site surveillance and security are drained, de-energized, and secured.

Access to contaminated areas is secured to provide controlled access for inspection and maintenance.
The engineering and planning requirements are similar to those for the DECON alternative, although they are limited in scope with no large scale dismantling activities anticipated. Site preparations are also similar to those for the DECON alternative. However, with the exception of the required radiation surveys and site characterizations, the mobilization and preparation of site facilities is less extensive.
2.2.1 Period 1 - Preparations Preparations for long-term storage include the planning for permanent defueling of the reactor, revision of technical specifications appropriate to the operating conditions and requirements, a characterization of the facility and major components, and the development of the PSDAR.
The process of placing the station in safe-storage includes, but is not limited to, the following activities:
o   Isolating of the spent fuel storage services and fuel handling systems so that safe-storage operations may commence on the balance of the plant. This activity may be carried out by plant personnel in accordance with existing operating technical specifications. Activities are scheduled around the fuel handling systems to the greatest extent possible.
o   Transferring of the spent fuel from the storage pools to the DOE or to the ISFSI for interim storage, following the minimum required cooling period in the spent fuel pools.
* Draining and de-energizing of the non-contaminated systems not required to support continued site operations or maintenance.
* Disposing of contaminated filter elements and resin beds not required for processing wastes from layup activities for future operations.
* Draining of the reactor vessel, with the internals left in place and the vessel head secured.
* Draining and de-energizing non-essential, contaminated systems with decontamination as required for future maintenance and inspection.

o   Erecting physical barriers and/or securing all access to radioactive or contaminated areas, except as required for inspection and maintenance.
o   Installing security and surveillance monitoring equipment and relocating security fence around secured structures, as required.
2.2.2 Period 2 - Dormancy The second phase identified by the NRC in its rule addresses licensed activities during a storage period and is applicable to the dormancy phases of the deferred decommissioning alternatives. Dormancy activities include a 24-hour security force, preventive and corrective maintenance on security systems, area lighting, general building maintenance, heating and ventilation of buildings, routine radiological inspections of contaminated structures, maintenance of structural integrity, and a site environmental and radiation monitoring program.
Resident maintenance personnel perform equipment maintenance, inspection activities, routine services to maintain safe conditions, adequate lighting, heating, and ventilation, and periodic preventive maintenance on essential site services.
An environmental surveillance program is carried out during the dormancy period to ensure that releases of radioactive material to the environment are prevented and/or detected and controlled. Appropriate emergency procedures are established and initiated for potential releases that exceed prescribed limits. The environmental surveillance program constitutes an abbreviated version of the program in effect during normal plant operations.
Security during the dormancy period is conducted primarily to prevent unauthorized entry and to protect the public from the consequences of its own actions. The security fence, sensors, alarms, and other surveillance equipment provide security. Fire and radiation alarms are also monitored and maintained.

The transfer of the spent fuel to the DOE continues throughout the dormancy period until completed in 2073. Once emptied, the ISFSI is secured for storage and decommissioned along with the power block structures in Period 4.
After a period of storage (such that license termination is accomplished within 60 years of final shutdown), it is required that the licensee submit an application to terminate the license, along with an LTP (described in Section 2.1.2), thereby initiating the third phase.
2.2.3 Periods 3 and 4 - Delayed Decommissioning Prior to the commencement of decommissioning operations, preparations are undertaken to reactivate site services and prepare for decommissioning. Preparations include engineering and planning, a detailed site characterization, and the assembly of a decommissioning management organization. Final planning for activities and the writing of activity specifications and detailed procedures are also initiated at this time.
Much of the work in developing a termination plan is relevant to the development of the detailed engineering plans and procedures. The activities associated with this phase and the follow-on decontamination and dismantling processes are detailed in Sections 2.1.1 and 2.1.2. The primary difference between the sequences anticipated for the DECON and this deferred scenario is the absence, in the latter, of any constraint on the availability of the fuel storage facilities for decommissioning.
The additional decay time is not expected to significantly affect the quantities of radioactive wastes generated from system and structure removal operations. Given the levels of radioactivity and spectrum of radionuclides expected from sixty years of plant operation, no plant process system identified as being contaminated upon final shutdown will become releasable due to the decay period alone, i.e., there is no significant reduction in the waste generated from the decommissioning activities. However, due to the lower activity levels, a greater percentage of the waste volume can be designated for off-site processing and recovery.
The delay in decommissioning also yields lower working area radiation levels. As such, the estimates for this delayed scenario incorporate TLG Services, Inc.

Although the initial radiation levels due to 60 Co will decrease during the dormancy period, the internal components of the reactor vessel will still exhibit sufficiently high radiation dose rates to require remote sectioning under water due to the presence of long-lived radionuclides such as 94Nb, 59 Ni, and 63Ni. Therefore, the dismantling procedures described for the DECON alternative would still be employed during this scenario. Portions of the biological shield wall will still be radioactive due to the presence of activated trace elements with long half-lives ( 152Eu and    154Eu). Decontamination will require controlled removal and disposal. It is assumed that radioactive corrosion products on inner surfaces of piping and components will not have decayed to levels that will permit unrestricted use or allow conventional removal.
These systems and components will be surveyed as they are removed and disposed of in accordance with the existing radioactive release criteria.
2.2.4 Period 5 - Site Restoration Following completion of decommissioning operations, site -restoration activities can begin. Dismantling, as a continuation of the decommissioning process, is clearly the most appropriate and cost-effective option, as described in Section 2.1.3. The basis for the dismantling cost in this scenario is consistent with that described for DECON, presuming the removal of structures and site facilities to a nominal depth of three feet below grade and the limited restoration of the site.

: 3. COST ESTIMATE The cost estimates prepared for decommissioning St. Lucie consider the unique features of the site, including the NSSS, power generation systems, support services, site buildings, and ancillary facilities. The basis of the estimates, including the sources of information relied upon, the estimating methodology employed, site-specific considerations, and other pertinent assumptions, is described in this section.
3.1 BASIS OF ESTIMATE The estimates were developed using the site-specific, technical information from the 2005 analysis. This information was reviewed for the current analysis and updated as deemed appropriate. The site-specific considerations and assumptions used in the previous evaluation were also revisited. Modifications were incorporated where new information was available or experience from ongoing decommissioning programs provided viable alternatives or improved processes.
3.2 METHODOLOGY The methodology used to develop the estimates follows the basic approach originally presented in the AIF/NESP-036 study report, "Guidelines for Producing Commercial Nuclear Power Plant Decommissioning Cost Estimates,"[ 171 and the DOE "Decommissioning Handbook."[1 81 These documents present a unit factor method for estimating decommissioning activity costs, which simplifies the estimating calculations. Unit factors for concrete removal ($/cubic yard), steel removal ($/ton), and cutting costs ($/inch) are developed using local labor rates. The activity-dependent costs are estimated with the item quantities (cubic yards and tons), developed from plant drawings and inventory documents. Removal rates and material costs for the conventional disposition of components and structures rely upon information available in the industry publication, "Building Construction Cost Data," published by R.S. Means.[ 19]
The unit factor method provides a demonstrable basis for establishing reliable cost estimates. The detail provided in the unit factors, including activity duration, labor costs (by craft), and equipment and consumable costs, ensures that essential elements have not been omitted. Appendix A presents the detailed development of a typical unit factor. Appendix B provides the values contained within one set of factors developed for this analysis.

In addition, the planning and engineering for the Pathfinder, Shoreham, Rancho Seco, Trojan, Yankee Rowe, Big Rock Point, Maine Yankee, Humboldt Bay-3, Oyster Creek, Connecticut Yankee, and San Onofre-1 nuclear units have provided additional insight into the process, the regulatory aspects, and the technical challenges of decommissioning commercial nuclear units.
Work Difficulty Factors TLG has historically applied work difficulty adjustment factors (WDFs) to account for the inefficiencies in working in a power plant environment. WDFs are assigned to each unique set of unit factors, commensurate with the inefficiencies associated with working in confined, hazardous environments.
The ranges used for the WDFs are as follows:
o   Access Factor                                   10% to 20%

The factors and their associated range of values were developed in conjunction with the AIF/NESP-036 study. The application of the factors is discussed in more detail in that publication.
Scheduling Program Durations The unit factors, adjusted by the WIDFs as described above, are applied against the inventory of materials to be removed in the radiological controlled areas.
The resulting man-hours, or crew-hours, are used in the development of the decommissioning program schedule, using resource loading and event sequencing considerations. The scheduling of conventional removal and dismantling activities is based upon productivity information available from the "Building Construction Cost Data" publication.
An activity duration critical path is used to determine the total decommissioning program schedule. The schedule is relied upon in calculating the carrying costs, which include program management, administration, field TLG Services,Inc.

This systematic approach for assembling decommissioning estimates ensures a high degree of confidence in the reliability of the resulting costs.
3.3 IMPACT OF DECOMMISSIONING MULTIPLE REACTOR UNITS In estimating the near simultaneous decommissioning of two co-located reactor units there can be opportunities to achieve economies of scale, by sharing costs between units, and coordinating the sequence of work activities. There will also be schedule constraints, particularly where there are requirements for specialty equipment and staff, or practical limitations on when final status surveys can take place. For purposes of the estimates, Units 1 and 2 are assumed to be essentially identical. Common facilities have been assigned to Unit 2. A summary of the principal impacts are listed below.
      "   The sequence of work generally follows the principal that the work is done at Unit 2 first, followed by similar work at Unit 1. This permits the experience gained at Unit 2 to be applied by the workforce at the second unit. It should be noted however, that the estimates do not consider productivity improvements at the second unit, since there is little documented experience with decommissioning two units simultaneously.
The work associated with developing activity specifications and procedures can, however, be considered essentially identical between the two units, therefore the second unit costs are assumed to be a fraction of the first unit (e.g., - 43% in DECON).
      "   Segmenting the reactor vessel and internals will require the use of special equipment. The decommissioning project will be scheduled such that Unit l's reactor internals and vessel are segmented after the activities at Unit 2 have been completed, permitting the sharing of the cutting equipment.
      " Some program management and support costs, particularly costs associated with the more senior positions, can be avoided with two reactors undergoing decommissioning simultaneously. As a result, the estimates are based on a "lead" unit that includes these senior positions, and a "second" unit that excludes these positions. The designation as lead is based on the unit undertaking the most complex tasks (for instance vessel segmentation) or performing tasks for the first time.
* The final radiological survey schedule    is also affected by a two-unit decommissioning schedule. It would be     considered impractical to try to complete the final status survey of Unit  2, while Unit 1 still has ongoing radiological remediation work and waste   handling in process. As such, the transfer of the spent fuel from the        storage pools and subsequent TLG Services, Inc.

o   The final demolition of buildings at Units 1 and 2 are considered to take place concurrently.
o   The first unit to enter decommissioning incurs the majority of site characterization costs.
o Shared systems and structures are generally assigned to Unit 2.
o   Station costs such as emergency response fees, regulatory agency fees, corporate overhead, and insurance are generally allocated on an equal basis between the two units.
o   Dormancy costs (to maintain the units in safe-storage) in the SAFSTOR scenario are allocated on an equal basis between the two units.
3.4 FINANCIAL COMPONENTS OF THE COST MODEL TLG's proprietary decommissioning cost model, DECCER, produces a number of distinct cost elements. These direct expenditures, however, do not comprise the total cost to accomplish the project goal, i.e., license termination and site restoration.
Inherent in any cost estimate that does not rely on historical data is the inability to specify the precise source of costs imposed by factors such as tool breakage, accidents, illnesses, weather delays, and labor stoppages. In the DECCER cost model, contingency fulfills this role. Contingency is added to each line item to account for costs that are difficult or impossible to develop analytically. Such costs are historically inevitable over the duration of a job of this magnitude; therefore, this cost analysis includes funds to cover these types of expenses.
3.4.1 Contingency The activity- and period-dependent costs are combined to develop the total decommissioning cost. A contingency is then applied on a line-item basis, using one or more of the contingency types listed in the AIF/NESP-036 study. "Contingencies" are defined in the American Association of Cost Engineers "Project and Cost Engineers' Handbook"[20 1 as "specific provision for unforeseeable elements of cost within the defined project scope; particularly important where previous experience relating estimates and actual costs has shown that unforeseeable events which will increase costs are likely to occur." The cost elements in this analysis are based upon ideal conditions and TLG Services,Inc.

In the AIF/NESP-036 study, the types of unforeseeable events that are likely to occur in decommissioning are discussed and guidelines are provided for percentage contingency in each category. It should be noted that contingency, as used in this analysis, does not account for price escalation and inflation in the cost of decommissioning over the remaining operating life of the station.
Contingency funds are an integral part of the total cost to complete the decommissioning process. Exclusion of this component puts at risk a successful completion of the intended tasks and, potentially, subsequent related activities. For this study, TLG examined the major activity-related problems (decontamination, segmentation, equipment handling, packaging, transport, and waste disposal) that necessitate a contingency. Individual activity contingencies ranged from 10% to 75%,
depending on the degree of difficulty judged to be appropriate from TLG's actual decommissioning experience. The contingency values used in this study are as follows:

A composite value is then reported at the end of each detailed estimate (as provided in Appendix C and D). For example,     the    composite    contingency    value reported       for   the decommissioning activity for the DECON alternative in Appendix C is approximately 17.5% and for the SAFSTOR alternative in Appendix D is approximately 16.7%.
3.4.2 Financial Risk In addition to the routine uncertainties addressed by contingency, another cost element that is sometimes necessary to consider when bounding decommissioning costs relates to uncertainty, or risk.
Examples can include changes in work scope, pricing, job performance, and other variations that could conceivably, but not necessarily, occur.
Consideration is sometimes necessary to generate a level of confidence in the estimate, within a range of probabilities. TLG considers these types of costs under the broad term "financial risk." Included within the category of financial risk are:
* Transition activities and costs: ancillary expenses associated with eliminating 50% to 80% of the site labor force shortly after the cessation of plant operations, added cost for worker separation packages throughout the decommissioning program, national or company-mandated retraining, and retention incentives for key personnel.
* Delays in approval of the decommissioning plan due to intervention, public participation in local community meetings, legal challenges, and national and local hearings.
* Changes in the project work scope from the baseline estimate, involving the discovery of unexpected levels of contaminants, contamination in places not previously expected, contaminated soil previously undiscovered (either radioactive or hazardous material contamination), variations in plant inventory or configuration not indicated by the as-built drawings.
* Regulatory changes, for example, affecting worker health and safety, site release criteria, waste transportation, and disposal.
* Policy decisions altering national commitments (e.g., in the ability to accommodate certain waste forms for disposition), or in the timetable for such, for example, the start and rate of acceptance of spent fuel by the DOE.

Items subject to widespread price competition (such as materials) may not show significant variation; however, others such as waste disposal could exhibit large pricing uncertainties, particularly in markets where limited access to services is available.
This cost study does not add any additional costs to the estimate for financial risk, since there is insufficient historical data from which to project future liabilities. Consequently, the areas of uncertainty or risk are revisited periodically and addressed through repeated revisions or updates of the base estimates.
3.5 SITE-SPECIFIC CONSIDERATIONS There are a number of site-specific considerations that affect the method for dismantling and removal of equipment from the site and the degree of restoration required. The cost impact of the considerations identified below is included in this cost study.
3.5.1 Spent Fuel Management The cost to dispose the spent fuel generated from plant operations is not reflected within the estimates to decommission St. Lucie. Ultimate disposition of the spent fuel is within the province of the DOE's Waste Management System, as defined by the Nuclear Waste Policy Act. As such, the disposal cost is financed by a 1 mill/kWhr surcharge paid into the DOE's waste fund during operations. However, the NRC requires licensees to establish a program to manage and provide funding for the management of all irradiated fuel at the reactor site until title of the fuel is transferred to the Secretary of Energy. This funding requirement is fulfilled through inclusion of certain high-level waste cost elements within the estimates, as described below.
Completion of the decommissioning process is highly dependent upon the DOE's ability to remove spent fuel from the site. The timing for removal of spent fuel from the site is based upon the DOE's most recently published annual acceptance rates of 400 MTU/year for year 1, 3,800 MTU total for years 2 through 4 and 3,000 MTU/year for year 5 and beyond. The DOE contracts provide mechanisms for altering the oldest fuel first allocation scheme, including emergency deliveries, exchanges of allocations amongst utilities and the option of providing priority acceptance from permanently. shutdown nuclear reactors.
Because it is unclear how these mechanisms may operate once DOE TLG Services, Inc.

St. Lucie Nuclear Plant,Units I and 2                         Document F02-1630-001, Rev. 0 DecommissioningCost Analysis                                          Section 3, Page 8 of 59 begins accepting spent fuel from commercial reactors, this study assumes that DOE will accept spent fuel in an oldest fuel first order.
ISFSI An ISFSI, which is operated under the plant's general license, has been constructed to support management of the spent fuel during operations.
The facility is assumed to be available to support spent fuel management once the units cease operation, until the DOE is able to removal all spent fuel from the site.
The ISFSI will continue to operate throughout decommissioning, and beyond the termination of the operating license in the DECON decommissioning alternative, until such time that the transfer of spent fuel to the DOE can be completed. Assuming, conservatively, that DOE begins to remove spent fuel from the site in 2032, the process is expected to be completed by the year 2073. The scenario is similar for the SAFSTOR alternative; however, based upon the expected completion date for fuel transfer, the ISFSI will be emptied prior to the commencement of decommissioning operations.
Post-shutdown and maintenance costs for the spent fuel pools and the ISFSI are also included and address the cost for staffing the facility, as well as security, insurance, and licensing fees. Costs are provided for the final disposition of the facilities once the transfer is complete.
Canister Desian A Transnuclear NUHOMS-32PT system (with a 32 fuel assembly capacity) is assumed for future acquisitions. For fuel transferred directly from the pools to the DOE, the DOE is assumed to provide Transport, Aging and Disposal (TAD) canisters with a 32 assembly capacity. DOE has not provided details about the TAD canisters other than assembly capacity.
Canister Loadina and Transfer The estimates include the cost for the labor and equipment to transfer and load each spent fuel canister into the DOE transport cask or to the ISFSI from the wet storage pools. Since the DOE has not published details about its cask system, this rough estimate is necessary. However, use of this estimate should not be used to infer that TLG has any detailed information on the cask system DOE will ultimately provide.

Pool operations are expected to continue approximately five and one half years after the cessation of operations. ISFSI operating costs are based upon a 30 year period of operations following the shutdown of Unit 2.
ISFSI Design Considerations A multi-purpose (storage and transport) dry shielded storage canister (DSC) with a horizontal storage module (HSM) is used as a basis for the cost analyses. The HSMs are assumed to have some level of neutron-induced activation as a result of the long-term storage of the fuel, i.e., to levels exceeding free-release limits. The cost of the disposition of this material, as well as the demolition of the ISFSI facility, is included in the estimates.
GTCC The dismantling of the reactor internals may generate radioactive waste considered unsuitable for shallow land disposal (i.e., low-level radioactive waste with concentrations of radionuclides that exceed the limits established by the NRC for Class C radioactive waste (GTCC)).
The Low-Level Radioactive Waste Policy Amendments Act of 1985 assigned the federal government the responsibility for the disposal of this material. The Act also stated that the beneficiaries of the activities resulting in the generation of such radioactive waste bear all reasonable costs of disposing of such waste. Although the DOE is responsible for disposing of GTCC waste, any costs for that service have not been determined. For purposes of this estimate, the GTCC radioactive waste is assumed to be packaged and disposed of as high-level waste, at a cost equivalent to that envisioned for the spent fuel.
For purposes of this study, GTCC is packaged in the same canisters used to store spent fuel. Disposal costs are based upon a cost equivalent to that envisioned for the spent fuel. It is not anticipated that the DOE would accept this waste prior to completing the transfer of spent fuel.
Therefore, until such time the DOE is ready to accept GTCC waste, it is reasonable to assume that this material would remain in storage at the St. Lucie site (for the DECON alternative). In the SAFSTOR alternative, the GTCC material is shipped directly to a DOE facility as it is removed TLG Services, Inc.

The estimates also include an additional GTCC canister (per unit) to accommodate the highly-activated legacy waste currently being stored in baskets in the spent fuel pool.
3.5.2 Reactor Vessel and Internal Components The reactor pressure vessel and internal components are segmented for disposal in shielded, reusable transportation casks. Segmentation is performed in the refueling canal, where a turntable and remote cutter are installed. The vessel is segmented in place, using a mast-mounted cutter supported off the lower head and directed from a shielded work platform installed overhead in the reactor cavity. Transportation cask specifications and transportation regulations dictate the segmentation and packaging methodology.
Intact disposal of reactor vessel shells has been successfully demonstrated at several of the sites that have been decommissioned.
Access to navigable waterways has allowed these large packages to be transported, in most instances, to the Barnwell disposal site in South Carolina with minimal overland travel.
Intact disposal of the reactor vessel and internal components can provide additional savings in cost and worker exposure by eliminating the complex segmentation requirements, isolation of the GTCC material, and transport/storage of the resulting waste packages. Portland General Electric (PGE) was able to dispose of the Trojan reactor as an intact package (including the internals). However, its location on the Columbia River simplified the transportation analysis since:
                "  the reactor package could be secured to the transport vehicle for the entire journey, i.e., the package was not lifted during transport,
                "  there were no man-made or natural terrain features between the plant site and the disposal location that could produce a large drop, and
                "  transport speeds were very low, limited by the overland transport vehicle and the river barge.

The characteristics of this arid site proved favorable in demonstrating compliance with land disposal regulations.
It is not known whether intact disposal (of the vessel shell or the complete vessel and internals) will be available when the St. Lucie plant ceases operation. Future viability of this option will depend upon the ultimate location of the disposal site, as well as the disposal site licensee's ability to accept highly radioactive packages and effectively isolate them from the environment. Consequently, this study assumes that the reactor vessel will require segmentation, as a bounding condition.
3.5.3 Primary System Components In the DECON alternative, the reactor coolant system components are assumed to be decontaminated using chemical agents prior to the start of dismantling operations. This type of decontamination can be expected to have a significant ALARA impact, since in this scenario the removal work is done within the first few years of shutdown. A decontamination factor (average reduction) of 10 is assumed for the process. Disposal of the decontamination solution effluent is included within the estimate as a "process chemical waste" charge. In the SAFSTOR alternative, radionuclide decay is expected to provide the same benefit and, therefore, a chemical decontamination is not included.
The following discussion deals with the removal and disposition of the steam generators, but the techniques involved are also applicable to other large components, such as heat exchangers, component coolers, and the pressurizer. The steam generators' size and weight, as well as their location within the reactor building, will ultimately determine the removal strategy.
A trolley crane is set up for the removal of the generators. It can also be used to move portions of the steam generator cubicle walls and floor slabs from the reactor building to a location where they can be decontaminated and transported to the material handling area.
Interferences within the work area, such as grating, piping, and other components are removed to create sufficient laydown space for processing these large components.

Each generator is rotated into the horizontal position for extraction from the containment and placed onto a multi-wheeled vehicle for transport to an on-site processing and storage area.
The generators are disassembled on-site with the steam domes and lightly contaminated subassemblies designated for off-site recycling. For cost estimating purposes, the more highly contaminated lower assembly containing the tube sheet and tube bundle are packaged for direct disposal, although additional processing may be an option. The interior volume is filled with low-density cellular concrete for stabilization of the internal contamination. Each component is then loaded onto a barge for transport to a railhead. The steam generators are then transferred to a dedicated train for transport to the disposal facility.
The original steam generators and reactor closure heads have been replaced at both units (along with the Unit 1 pressurizer and a Unit 2 reactor coolant pump motor). The replaced components have been shipped off-site for controlled disposal and are therefore not addressed in this analysis.
Reactor coolant piping is cut from the reactor vessel once the water level in the vessel (used for personnel shielding during dismantling and cutting operations in and around the vessel) is dropped below the nozzle zone. The piping is boxed and transported by shielded van. The reactor coolant pumps and motors are lifted out intact, packaged, and transported for processing and/or disposal.
3.5.4 Main Turbine and Condenser The main turbine is dismantled using conventional maintenance procedures. The turbine rotors and shafts are removed to a laydown area. The lower turbine casings are removed from their anchors by controlled demolition. The main condensers are also disassembled and moved to a laydown area. Material is then prepared for transportation to an off-site recycling facility where it is surveyed and designated for either decontamination or volume reduction, conventional disposal, or controlled disposal. Components are packaged and readied for transport in accordance with the intended disposition.

The reactor vessel and internal components are expected to be transported in accordance with 10 CFR Part 71, as Type B. It is conceivable that the reactor, due to its limited specific activity, could qualify as LSA II or III.
However, the high radiation levels on the outer surface would require that additional shielding be incorporated within the packaging so as to attenuate the dose to levels acceptable for transport.
Any fuel cladding failure that occurred during the lifetime of the plant is assumed to have released fission products at sufficiently low levels that the buildup of quantities of long-lived isotopes (e.g., 137 Cs, 9 0Sr, or transuranics) has been prevented from reaching levels exceeding those that permit the major reactor components to be shipped under current transportation regulations and disposal requirements.
Transport of the highly-activated metal, produced in the segmentation of the reactor vessel and internal components, will be by shielded truck cask. Cask shipments may exceed 95,000 pounds, including vessel segment(s), supplementary shielding, cask tie-downs, and tractor-trailer. The maximum level of activity per shipment assumed permissible was based upon the license limits of the available shielded transport casks. The segmentation scheme for the vessel and internal segments is designed to meet these limits.
The transport of large intact components (e.g., large heat exchangers and other oversized components) will be by a combination of truck, barge, rail, and/or multi-wheeled transporter.
Transportation costs for material requiring controlled disposal are based upon the mileage to EnergySolutions' facility in Clive, Utah.
Transportation costs for off-site waste processing are based upon the mileage to Oak Ridge, Tennessee. Truck transport costs are estimated 22 using published tariffs from Tri-State Motor Transit.[ ]

The waste containers, once emptied, are returned to the St. Lucie site for reuse.
3.5.6 Low-Level Radioactive Waste Disposal To the greatest extent practical, metallic material generated in the decontamination and dismantling processes is processed to reduce the total cost of controlled disposal. Material meeting the regulatory and/or site release criterion, is released as scrap, requiring no further cost consideration. Conditioning (preparing the material to meet. the waste acceptance criteria of the disposal site) and recovery of the waste stream is performed off site at a licensed processing center. Any material leaving the site is subject to a survey and release charge, at a minimum.
The mass of radioactive waste generated during the various decommissioning activities at the site is shown on a line-item basis in the detailed Appendices C and D, and summarized in Section 5. The quantified waste summaries shown in these tables are consistent with 10 CFR Part 61 classifications. Commercially available steel containers are presumed to be used for the disposal of piping, small components, and concrete. Larger components can serve as their own containers, with proper closure of all openings, access ways, and penetrations. The volumes are calculated based on the exterior package dimensions for containerized material or a specific calculation for components serving as their own waste containers.
The more highly-activated reactor components will be shipped in reusable, shielded truck casks with disposable liners. In calculating disposal costs, the burial fees are applied against the liner volume, as well as the special handling requirements of the payload. Packaging efficiencies are lower for the highly-activated materials (greater than Type A quantity waste), where high concentrations of gamma-emitting radionuclides limit the capacity of the shipping canisters.
Disposal fees are based upon estimated charges, with surcharges added for the highly-activated components, for example, generated in the segmentation of the reactor vessel. The cost to dispose of the lowest level and majority of the material generated from the decontamination and dismantling activities is based upon FPL's current cost for disposal at the EnergySolutions facility in Clive, Utah. Disposal costs for the higher activity waste (Class B and C) were based upon the last published rate TLG Services, Inc.

3.5.7 Site Conditions Following Decommissioning The NRC will terminate the site license if it determines that site remediation has been performed in accordance with the license termination plan, and that the terminal radiation survey and associated documentation demonstrate that the facility is suitable for release. The NRC's involvement in the decommissioning process will end at this point. Building codes and environmental regulations will dictate the next step in the decommissioning process, as well as the owner's own future plans for the site.
Non-essential structures or buildings severely damaged in decontamination process are removed to a nominal depth of three feet below grade. Concrete rubble generated from demolition activities is processed and made available as clean fill for the power block foundations. Excess construction debris is trucked off site as an alternative to onsite disposal. The excavations will be regraded such that the power block area will have a final contour consistent with adjacent surroundings.
The existing electrical switchyard and access roads will remain in support of the electrical transmission and distribution system. The site access road will be left intact.
3.6 ASSUMPTIONS The following are the major assumptions made in the development of the estimates for decommissioning the site.
3.6.1 Estimating Basis The study follows the principles of ALARA through the use of work duration adjustment factors. These factors address the impact of activities such as radiological protection instruction, mock-up training, and the use of respiratory protection and protective clothing. The factors lengthen a task's duration, increasing costs and lengthening the overall schedule. ALARA planning is considered in the costs for engineering and planning, and in the development of activity specifications and detailed procedures. Changes to worker exposure limits may impact the decommissioning cost and project schedule.

The current cost of labor at the site is used as an estimating basis. Costs for site administration, operations, construction, and maintenance personnel are based upon average salary information provided by FPL.
FPL will hire a Decommissioning Operations Contractor (DOC) to manage the decommissioning. The licensee will provide site security, radiological health and safety, quality assurance and overall site administration during the decommissioning and demolition phases.
Contract personnel will provide engineering services, e.g., for preparing the activity specifications, work procedures, activation, and structural analyses, under the direction of the owner.
Reductions in the operating organization are handled through normal company practices. No costs have been included for this activity.
Security, while reduced from operating levels, is maintained throughout the decommissioning for access control, material control, and to safeguard the spent fuel.
3.6.3 Design Conditions Any fuel cladding failure that occurred during the lifetime of the plant is assumed to have released fission products at sufficiently low levels that the buildup of quantities of long-lived isotopes (e.g., 13 7Cs, 90 Sr, or transuranics) has been prevented from reaching levels exceeding those that permit the major NSSS components to be shipped under current transportation regulations and disposal requirements.
The curie contents of the vessel and internals at final shutdown are derived from those listed in NUREG/CR-3474.[231 Actual estimates are derived from the curie/gram values contained therein and adjusted for the different mass of the St. Lucie components, projected operating life, and different periods of decay. Additional short-lived isotopes were derived from NUREG/CR-0130[241            and NUREG/CR-0672,[ 2 51 and benchmarked to the long-lived values from NUREG/CR-3474.
The control elements are disposed of along with the spent fuel, i.e., there is no additional cost provided for their disposal.

St. Lucie Nuclear Plant, Units 1 and 2                     Document F02-1630-001, Rev. 0 DecommissioningCost Analysis                                      Section 3, Page 17 of 59 This study assumes that contamination (activation) of the containment building structure is confined to the biological shield. It should be noted that more extensive activation (at very low levels) of the interior structures within containment has been detected at several reactors and the owners have elected to dispose of the affected material at a controlled facility rather than reuse the material as fill on site or send it to a landfill. The ultimate disposition of the material removed from the reactor building will depend upon the site release criteria selected, as well as the designated end use for the site.
Contaminated Soil The estimates include an allowance for the remediation of contaminated soil and storm drains at several site areas that have been identified by FPL to contain concentrations of radionuclides in excess of NRC release limits. The areas include the primary and refueling water storage tanks, the east settling pond, storm drain system and the contaminated discharge canal dredge spoils pile. The requirements assumed for soil remediation may be affected by continued plant operations and/or future regulatory actions, such as the development of site-specific release criteria.
Asbestos and Hazardous Waste The estimates include an allowance for the remediation of asbestos structural fireproofing coatings at Unit 1, removal of soil contaminated with diesel fuel and lubricating oil at both Unit 1 and Unit 2, and disposal of mixed/hazardous waste left over from plant operations.
3.6.4 General Transition Activities Existing warehouses are cleared of non-essential material and remain for use by FPL and its subcontractors. The plant's operating staff performs the following activities at no additional cost or credit to the project during the transition period:
                "  Drain and collect fuel oils, lubricating oils, and transformer oils for recycle and/or sale.
* Drain and collect acids, caustics, and other chemical stores for recycle and/or sale.

The estimates do not address the disposition of any legacy or retired components (except for the highly-activated material currently stored in the spent fuel pool and some mixed/hazardous wastes).
Scrap and Salvage The existing plant equipment is considered obsolete and suitable for scrap as deadweight quantities only. FPL will make economically reasonable efforts to salvage equipment following final plant shutdown.
However, dismantling techniques assumed by TLG for equipment in this analysis are not consistent with removal techniques required for salvage (resale) of equipment. Experience has indicated that some buyers wanted equipment stripped down to very specific requirements before they would consider purchase. This required expensive rework after the equipment had been removed from its installed location. Since placing a salvage value on this machinery and equipment would be speculative, and the value would be small in comparison to the overall decommissioning expenses, this analysis does not attempt to quantify the value that an owner may realize based upon those efforts.
It is assumed, for purposes of this analysis, that any value received from the sale of scrap generated in the dismantling process would be more than offset by the on-site processing costs. The dismantling techniques assumed in the decommissioning estimates do not include the additional cost for size reduction and preparation to meet "furnace ready" conditions. For example, the recovery of copper from electrical cabling may require the removal and disposition of any contaminated insulation, an added expense. With a volatile market, the potential profit margin in scrap recovery is highly speculative, regardless of the ability to free release this material. This assumption is an implicit recognition of scrap value in the disposal of clean metallic waste at no additional cost to the project.
Furniture, tools, mobile equipment such as forklifts, trucks, bulldozers, and other property is removed at no cost or credit to the decommissioning project. Disposition may include relocation to other facilities. Spare parts are also made available for alternative use.

Replacement power costs are used to calculate the cost of energy consumed during decommissioning for tooling, lighting, ventilation, and essential services.
Insurance Costs for continuing coverage (nuclear liability and property insurance) following cessation of plant operations and during decommissioning are included and based upon current operating premiums. Reductions in premiums, throughout the decommissioning process, are based upon the guidance and the limits for coverage defined in the NRC's proposed rulemaking "Financial Protection Requirements for Permanently Shutdown Nuclear Power Reactors."[ 26 ] The NRC's financial protection requirements are based on various reactor (and spent fuel) configurations.
Taxes Property taxes assessed during decommissioning are considered a decommissioning cost. From the time Unit 1 ceases operation to the end of year 2043 (the year in which Unit 2 ceases operation), taxes for the site are assumed to be assessed on the land value only (assuming no significant value for the site structures). After 2043, the tax charged to decommissioning is reduced to the portion of the tax applicable to only the protected area and ISFSI. This assessment (split 50/50 between the units) continues to be applied until the site is released for unrestricted use.
Site Modifications The perimeter fence and in-plant security barriers will be moved, as appropriate, to conform to the Site Security Plan in force during the various stages of the project.
Site Restoration All structures will be removed except for the switchyard and discharge diffuser. The switchyard is required for grid operations. The discharge diffuser will be removed at the breakaway flange and a plug welded in TLG Services, Inc.

3.7 COST ESTIMATE 

==SUMMARY==

Schedules of expenditures are provided in Tables 3.1 through 3.4 for the DECON and SAFSTOR alternatives. The tables delineate the cost contributors by year of expenditures as well as cost contributor (e.g., labor, materials, and waste disposal).
Additional tables in Appendices C and D provide detailed cost elements. The cost elements are also assigned to one of three subcategories: "License Termination,"
      "Spent Fuel Management," and "Site Restoration." The subcategory "License Termination" is used to accumulate costs that are consistent with "decommissioning" as defined by the NRC in its financial assurance regulations (i.e., 10 CFR &sect;50.75). The cost reported for this subcategory is generally sufficient to terminate the plant's operating license, recognizing that there may be some additional cost impact from spent fuel management.
The "Spent Fuel Management" subcategory contains costs anticipated to be incurred once the nuclear units cease operation for the off-loading of the pools either directly to the DOE or to the ISFSI for interim storage, and the eventual transfer of dry shielded canisters from the ISFSI to the DOE. Costs are also included for the operation of the ISFSI until such time that the transfer of all fuel from this facility to an off-site location (e.g., geologic repository) is complete.
      "Site Restoration" is used to capture costs associated with the dismantling and demolition of buildings and facilities demonstrated to be free from contamination. This includes structures never exposed to radioactive materials, as well as those facilities that have been decontaminated to appropriate levels. Structures are removed to a depth of three feet and backfilled to conform to local grade.
As discussed in Section 3.4.1, it is not anticipated that the DOE will accept the GTCC waste prior to completing the transfer of spent fuel. Therefore, the cost of GTCC disposal is shown in the final year of ISFSI operation (for the DECON alternative). While designated for disposal at the geologic repository along with the spent fuel, GTCC waste is still classified as low-level radioactive waste and, as such, included as a "License Termination" expense.

St. Lucie Nuclear Plant, Units I and 2                     Document F02-1630-001, Rev. 0 Decommissioning Cost Analysis                                    Section 3, Page 21 of 59 Decommissioning costs are reported in 2010 dollars. Costs are not inflated, escalated, or discounted over the period of expenditure (or projected lifetime of the plant). The schedules are based upon the detailed activity costs reported in Appendices C and D, along with the timeline presented in Section 4.
The "Burial" column contains costs for the processing of low-level radioactive waste, as well as for the controlled disposal of material that cannot be recovered (released for unrestricted use). Since the following tables are often used in escalation analyses, costs associated with the disposition of GTCC have been reassigned to the "Other" column, commensurate with contractual payments for a one-time disposal service, although the cost is still reported in the "LLRW Disposal Costs" column in Appendices C and D and as a "Waste Disposal" cost in the summary tables (i.e., on pages xvii, xviii, 6-4 and 6-5).
      "Off-site Waste Processing," separately reported in the summary tables, has been included in the "Burial" column as well.

On March 31, 2009, FPL executed a Settlement Agreement with the DOE and the Department of Justice (DoJ). In the Agreement, FPL settled the lawsuit in exchange for payments. The payments are intended to cover those costs incurred for managing and storing the spent fuel that it would not have incurred but for DOE's delay in performance.
While the DOE is responsible for the costs incurred until it fulfills its obligation, certain assumptions are needed to assess the financial impact on the previously identified decommissioning cost scenarios. The assumptions and methodology employed to quantify the expected level of compensation are as follows:
: 1. DOE Acceptance Obligations are defined based on the 1995 Acceptance Priority Ranking & Annual Capacity Report Table 1 acceptance rate from Year 1 to Year 10, with a continued steady state acceptance rate of 900 metric tons of uranium (MTU) per year until December 31, 2014 and 2,100 MTU/year thereafter as per the Settlement Agreement.
: 2. At the time the aggregate MTUs actually accepted by the DOE equals the aggregate MTUs allocated to FPL under the 1995 Acceptance Priority Ranking & Annual Capacity Report, the DOE's compensation obligation ceases.
: 3. The pickup of commercial fuel is assumed to begin in the year 2030. The first fuel from St. Lucie is expected to be transferred to the DOE in 2032, again assuming commercial fuel is accepted on an oldest fuel first basis.t The rate of transfer was based upon an annual acceptance capacity at the geologic repository of 3,000 metric tons.
t   DOE's contracts with utilities order the acceptance of spent fuel from utilities based upon the oldest fuel receiving the highest priority. While DOE's acceptance priority ranking is based on the date that spent nuclear fuel was permanently discharged, with the oldest spent nuclear fuel, on an industry-wide basis, given the higher priority, the generator has the right to determine which spent nuclear fuel is delivered, provided that it is in compliance with the Standard Contract. DOE contracts also provide mechanisms for altering the oldest fuel first allocation scheme, including emergency deliveries, exchanges of allocations amongst utilities and the option of providing priority acceptance from permanently shutdown nuclear reactors.

Annual Capacity Report is based upon an earlier start date (1998), but a lower rate of acceptance than that considered in the St. Lucie decommissioning analysis. As shown in Table 3.6, the two different pickup rates would achieve the same level of performance (equivalent number of St. Lucie spent fuel assemblies received by the DOE) in the year 2062 (approximately eleven years before the ISFSI would be decommissioned).
Under the terms of the Settlement Agreement, if the DOE follows the pickup rate, its compensation obligation would terminate when this milestone is reached. Under this scenario, the DOE would provide no compensation after 2062.
: 4. This analysis addresses only those costs identified as spent fuel management costs in the decommissioning cost analysis (as delineated in the detailed cost tables in Appendix C and D). While the estimates do assign costs to spent fuel management during the active decommissioning period, the cost elements are generally limited in scope to the direct costs associated with purchasing DSCs and HSMs, loading and packaging the spent fuel into the canisters for long-term storage at the plant's ISFSI (or into TADs for direct transfer to the DOE). No attempt was made, for this analysis, to identify any additional ISFSI related costs during this time period that may also be eligible for reimbursement by DOE under the Agreement.
As shown on the graph at the bottom of Table 3.6, it is projected that the DOE will meet its obligation for cumulative acceptance of spent fuel in the year 2062, based upon the assumptions delineated in the decommissioning cost analysis. Costs incurred for spent fuel management prior to this time (conservatively, December 31, 2061) can be expected to be reimbursed. Costs incurred after that time would not be eligible. Each year, the claim requesting the prior year's costs is submitted for payment on or before April 30.
The activities (at a minimum), identified in the decommissioning cost study and expected to be eligible for reimbursement (depending upon the timing of the activities) are identified below.

However, they will be recovered on an ongoing basis (i.e., the year after expenditure). Tables 3.7 and 3.8 identify the income stream that can be expected to offset spent fuel management expenses for the decommissioning scenarios. Under the current assumptions, costs incurred in the year 2062 and beyond would not be eligible for reimbursement.
Table 3.9 identifies cost to decommission the ISFSI. While the costs are incurred after 2061, they may also be reimbursable since ISFSI construction was in response to delays in the timely removal of spent fuel from the site.

: 4. SCHEDULE ESTIMATE The schedules for the decommissioning scenarios considered in this study follow the sequences presented in the AIF/NESP-036 study, with minor changes to reflect recent experience and site-specific constraints. In addition, the scheduling has been revised to reflect the spent fuel management plan described in Section 3.5.1.
A schedule or sequence of activities for the DECON alternative is presented in Figure 4.1. The scheduling sequence is based on the fuel being removed from the spent fuel pools within five and one half years. The key activities listed in the schedule do not reflect a one-to-one correspondence with those activities in the cost tables, but reflect dividing some activities for clarity and combining others for convenience. The schedule was prepared using the "Microsoft Project Professional 2007" computer software.[27]
4.1   SCHEDULE ESTIMATE ASSUMPTIONS The schedule reflects the results of a precedence network developed for the site decommissioning activities, i.e., a PERT (Program Evaluation and Review Technique) Software Package. The work activity durations used in the precedence network reflect the actual man-hour estimates from the cost table, adjusted by stretching certain activities over their slack range and shifting the start and end dates of others. The following assumptions were made in the development of the decommissioning schedule:
      " The fuel handling area is isolated until such time that all spent fuel has been discharged from the spent fuel pools to the DOE or to the ISFSI for interim storage. Decontamination and dismantling of the storage pools is initiated once the transfer of spent fuel is complete (DECON alternative).
      "   All work (except vessel and internals removal) is performed during an 8-hour workday, 5 days per week, with no overtime. There are eleven paid holidays per year.
      " Reactor and internals removal activities are performed by using separate crews for different activities working on different shifts, with a corresponding backshift charge for the second shift.
      " Multiple crews work parallel activities to the maximum extent possible, consistent with optimum efficiency, adequate access for cutting, removal and laydown space, and with the stringent safety measures necessary during demolition of heavy components and structures.

4.2 PROJECT SCHEDULE The period-dependent costs presented in the detailed cost tables are based upon the durations developed in the schedules for decommissioning. Durations are established between several milestones in each project period; these durations are used to establish a critical path for the entire project. In turn, the critical path duration for each period is used as the basis for determining the period-dependent costs. A second critical path is shown for the spent fuel storage period, which determines the release of the fuel storage area for final decontamination.
Project timelines are provided in Figures 4.2 and 4.3, with milestone dates based on the 2036 and 2043 shutdown dates for Units 1 and 2, respectively. The fuel pools are emptied approximately five and one half years after shutdown, while ISFSI operations continue until the DOE can complete the transfer of assemblies to its geologic repository. Deferred decommissioning in the SAFSTOR alternative is assumed to commence so that the operating license is terminated within a 60-year period from the cessation of plant operations.

: 5. RADIOACTIVE WASTES The objectives of the decommissioning process are the removal of all radioactive material from the site that would restrict its future use and the termination of the NRC license. This currently requires the remediation of all radioactive material at the site in excess of applicable legal limits. Under the Atomic Energy Act,[28] the NRC is responsible for protecting the public from sources of ionizing radiation. Title 10 of the Code of Federal Regulations delineates the production, utilization, and disposal of radioactive materials and processes. In particular, Part 71 defines radioactive material as it pertains to transportation and Part 61 specifies its disposition.
Most of the materials being transported for controlled burial are categorized as Low Specific Activity (LSA) or Surface Contaminated Object (SCO) materials containing Type A quantities, as defined in 49 CFR Parts 173-178. Shipping containers are required to be Industrial Packages (IP-1, IP-2 or IP-3, as defined in 10 CFR
&sect;173.411). For this study, commercially available steel containers are presumed to be used for the disposal of piping, small components, and concrete. Larger components can serve as their own containers, with proper closure of all openings, access ways, and penetrations.
The volumes of radioactive waste generated during the various decommissioning activities at the site are shown on a line-item basis in Appendices C and D, and summarized in Tables 5.1 and 5.2. The quantified waste volume summaries shown in these tables are consistent with 10 CFR Part 61 classifications. The volumes are calculated based on the exterior dimensions for containerized material and on the displaced volume of components serving as their own waste containers.
The reactor vessel and internals are categorized as large quantity shipments and, accordingly, will be shipped in reusable, shielded truck casks with disposable liners.
In calculating disposal costs, the burial fees are applied against the liner volume, as well as the special handling requirements of the payload. Packaging efficiencies are lower for the highly-activated materials (greater than Type A quantity waste),
where high concentrations of gamma-emitting radionuclides limit the capacity of the shipping canisters.
No process system containing/handling radioactive substances at shutdown is presumed to meet material release criteria by decay alone (i.e., systems radioactive at shutdown will still be radioactive over the time period during which the decommissioning is accomplished, due to the presence of long-lived radionuclides).

Material that is considered potentially contaminated when removed from the radiological controlled area is sent to processing facilities in Tennessee for conditioning and disposal. Heavily contaminated components and activated materials are routed for controlled disposal. The disposal volumes reported in the tables reflect the savings resulting from reprocessing and recycling.
For purposes of constructing the estimates, FPL's current cost for disposal at the EnergySolutions facility was used. Separate rates were used for containerized waste and large components, including the steam generators and reactor coolant pump motors. Demolition debris including miscellaneous steel, scaffolding, and concrete was disposed of at a bulk rate. The decommissioning waste stream also included resins and dry active waste.
Since EnergySolutions is not currently able to receive the more highly radioactive components generated in the decontamination and dismantling of the reactor, disposal costs for the Class B and C material were based upon the last published rate schedule for non-compact waste for the Barnwell facility (as a proxy), adjusted for escalation of the Atlantic Compact rates. Additional surcharges were included for activity, dose rate, and/or handling added as appropriate for the particular package.

: 6. RESULTS The analysis to estimate the costs to decommission St. Lucie relied upon the site-specific, technical information developed for a previous analysis prepared in 2005, updated to reflect current assumptions pertaining to the disposition of the nuclear station and relevant industry experience in undertaking such projects. While not an engineering study, the estimates provide FPL with sufficient information to assess their financial obligations, as they pertain to the eventual decommissioning of the nuclear station.
The estimates described in this report are based on numerous fundamental assumptions, including a 60-year operating life, regulatory requirements, project contingencies, low-level radioactive waste disposal practices, high-level radioactive waste     management      options,     and  site  restoration   requirements.      The decommissioning scenarios assume continued operation of the station's spent fuel pools for a minimum of five and one half years following the cessation of operations for continued cooling of the assemblies.
The cost projected to promptly decommission the station, manage the spent fuel, and restore the site is estimated to be $1,478.8 million. The majority of this cost (approximately 71.2%) is associated with the physical decontamination and dismantling of the nuclear plant so that the operating license can be terminated.
Another 22.4% is associated with the management, interim storage, and eventual transfer of the spent fuel. The remaining 6.4% is for the demolition of the designated structures and limited restoration of the site.
The cost projected for deferred decommissioning (SAFSTOR) is estimated to be
$1,725.6 million. The majority of this cost (approximately 71.9%) is associated with placing the plant in storage, ongoing caretaking of the plant during dormancy, and the eventual physical decontamination and dismantling of the nuclear plant so that the operating license can be terminated. Another 22.3% is associated with the management, interim storage, and eventual transfer of the spent fuel. The remaining 5.8% is for the demolition of the designated structures and limited restoration of the site.
The primary cost contributors, identified in Tables 6.1 and 6.2, are either labor-related or associated with the management and disposition of the radioactive waste.
Program management is the largest single contributor to the overall cost. The magnitude of the expense is a function of both the size of the organization required to manage the decommissioning, as well as the duration of the program. It is assumed, for purposes of this analysis, that FPL will hire a Decommissioning Operations Contractor (DOC) to manage the decommissioning. The owner will TLG Services, Inc.

St. Lucie Nuclear Plant,Units 1 and 2                      Document F02-1630-001, Rev. 0 DecommissioningCost Analysis                                         Section 6, Page 2 of 5 provide site security, radiological health and safety, quality assurance and overall site administration during the decommissioning and demolition phases. Contract personnel will provide engineering services, e.g., for preparing the activity specifications, work procedures, activation, and structural analyses, under the direction of the owner. The size and composition of the management organization varies with the decommissioning phase and associated site activities. However, once the operating licenses are terminated, the staff is substantially reduced for the conventional demolition and restoration of the site, and the long-term care of the spent fuel (for the DECON alternative).
As described in this report, the spent fuel pools will remain operational for a minimum of five and one half years following the cessation of operations. The pools will be isolated and an independent spent fuel island created. This will allow decommissioning operations to proceed in and around the pool area. Over the five and one half-year period, the spent fuel will be packaged into transportable canisters for loading into a DOE-provided transport cask or relocation to the ISFSI.
The cost for waste disposal includes only those costs associated with the controlled disposition of the low-level radioactive waste generated from decontamination and dismantling activities, including plant equipment and components, structural material, filters, resins and dry-active waste. As described in Section 5, disposition of the majority of the low-level radioactive material requiring controlled disposal is at the EnergySolutions' facility. Highly activated components, requiring additional isolation from the environment (GTCC), are packaged for geologic disposal. The cost of geologic disposal is based upon a cost equivalent for spent fuel.
A significant portion of the metallic waste is designated for additional processing and treatment at an off-site facility. Processing reduces the volume of material requiring controlled disposal through such techniques and processes as survey and sorting, decontamination, and volume reduction. The material that cannot be unconditionally released is packaged for controlled disposal at one of the currently operating facilities. The cost identified in the summary tables for processing is all-inclusive, incorporating the ultimate disposition of the material.
Removal costs reflect the labor-intensive nature of the decommissioning process, as well as the management controls required to ensure a safe and successful program.
Decontamination and packaging costs also have a large labor component that is based upon prevailing wages. Non-radiological demolition is a natural extension of the decommissioning process. With a work force mobilized to support decommissioning operations, non-radiological demolition can be an integrated activity and a logical expansion of the work being performed in the process of terminating the operating license. Prompt demolition reduces future liabilities and TLG Services, Inc.

The reported cost for transport includes the tariffs and surcharges associated with moving large components and/or overweight shielded casks overland, as well as the general expense, e.g., labor and fuel, of transporting material to the destinations identified in this report. For purposes of this analysis, material is primarily moved overland by truck.
Decontamination is used to reduce the plant's radiation fields and minimize worker exposure. Slightly contaminated material or material located within a contaminated area is sent to an off-site processing center, i.e., this analysis does not assume that contaminated plant components and equipment can be decontaminated for uncontrolled release in-situ. Centralized processing centers have proven to be a more economical means of handling the large volumes of material produced in the dismantling of a nuclear plant.
License termination survey costs are associated with the labor intensive and complex activity of verifying that contamination has been removed from the site to the levels specified by the regulating agency. This process involves a systematic survey of all remaining plant surface areas and surrounding environs, sampling, isotopic analysis, and documentation of the findings. The status of any plant components and materials not removed in the decommissioning process will also require confirmation and will add to the expense of surveying the facilities alone.
The remaining costs include allocations for heavy equipment and temporary services, as well as for other expenses such as regulatory fees and the premiums for nuclear insurance. While site operating costs are greatly reduced following the final cessation of plant operations, certain administrative functions do need to be maintained either at a basic functional or regulatory level.

==SUMMARY==

This document provides a comparative discussion on decommissioning cost estimates prepared for the St. Lucie Nuclear Plant (St. Lucie) in 2005111 and updated in 2010[2] by TLG Services, Inc. (TLG). The estimates described in this document were constructed from a prompt decommissioning scenario following the scheduled cessation of operations, recognizing that there is a seven year offset in the scheduled shutdown dates for the two nuclear units. The scope of the two estimates is consistent, including cost elements for license termination, spent fuel management and site restoration activities.
The estimates were generated in 2004 and 2010 dollars, respectively. For purposes of comparison, they are referred to by their financial bases. The 2010, or current estimate, was developed using the basic inventory and plant design information from the 2004 or previous cost model. The data, estimating assumptions and site-specific considerations were reviewed for the 2010 analysis. The cost model was modified where new information was available, updated site-specific information was obtained, or experience from past decommissioning programs justified such changes.
The overall estimate to decommission St. Lucie increased approximately 43% over the six year period between estimates. The increase (or decrease) in the individual cost elements that comprise the estimates is shown in Table 1.
The cost elements were assigned to one of three subcategories: NRC License Termination, Spent Fuel Management, and Site Restoration. Delegation of cost elements into these categories was for the purpose of comparison (e.g., with NRC financial guidelines) or to permit specific financial treatment (e.g., ARO determinations). In reality, there can be considerable interaction or overlap between the activities in the three subcategories.
The subcategory NRC License Termination was used to accumulate costs that are consistent with the NRC's definition of decommissioning in its financial assurance regulations (i.e., 10 CFR Part 50.75). The cost reported for this subcategory is generally sufficient to terminate the operating licenses for the two reactors, recognizing that there may be some additional cost impact from spent fuel management. The cost associated with St. Lucie license termination activities 1   "Decommissioning Cost Analysis for the St. Lucie Nuclear Plant, Units 1 and 2," TLG Document F02-1512-002, Rev. 0, dated October 2005.

St. Lucie NuclearPlant, Units I and 2                       Document F02-1630-003, Rev. 0 Comparison Report 2004- 2010                                                Page vi of vii increased 34% over the six years. Major contributors included: an increase in the volume of low-level radioactive waste designated for controlled disposal or processing (which resulted in higher removal, transport, packaging, and waste disposal costs), higher site operating costs for items related to energy, security, fees and insurance, and a general increase in the cost of labor and materials.
The Spent Fuel Management subcategory contains costs anticipated to be incurred once the nuclear units cease operation for the off-loading of the pools either directly to the Department of Energy (DOE) or to the Independent Spent Fuel Storage Installation (ISFSI) for interim storage, and the eventual transfer of fuel from the ISFSI to the DOE. Costs were also included for the operation of the ISFSI until such time that the transfer of all fuel from this facility to an off-site location (e.g.,
geologic repository or interim facility) is complete. The costs assigned to this subcategory increased 97% over the six years. This was a consequence of a 15-year delay in the assumed commencement of commercial spent fuel pickup by the DOE and a resulting 13-year longer ISFSI operating period. This delay resulted in more fuel being transferred at the ISFSI for interim storage (80 additional dry shielded canisters and horizontal storage modules) in the 2010 cost model. Higher site operating costs, including security, were compounded by the longer ISFSI operating period.
Site Restoration was used to capture costs associated with the dismantling and demolition of buildings and facilities demonstrated to be free from contamination.
This includes structures never exposed to radioactive materials, as well as those facilities that have been decontaminated to appropriate levels. Structures are removed to a depth of three feet below grade and backfilled to conform to local grade. The costs assigned to this subcategory increased 10% over the six years. This modest increase is the result of increases in labor and material costs which were partially offset by savings resulting from a continuing optimization of the demolition management organization.

St. Lucie NuclearPlant, Units I and 2                      Document F02-1630-003, Rev. 0 ComparisonReport 2004 - 2010                                                 Page I of 15 COMPARATIVE ANALYSIS TLG completed a decommissioning cost analysis for St. Lucie in 2005. The analysis provided the Florida Power & Light Company (FPL), the majority owner and operator of the nuclear units, with the projected costs (in 2004 dollars) to completely decontaminate and dismantle the station following the normal cessation of plant operations. For purposes of this comparison, this analysis is referred to as the 2004 estimate or previous analysis.
In 2010, TLG updated the cost analysis for FPL. The current analysis uses the physical plant inventory and design information from the previous analysis. This data was reviewed, along with the assumptions and other site-specific considerations, and modified or updated where new information was available or experience from ongoing decommissioning programs justified such changes. Since the update relied upon 2010 economic data, the analysis is referred to as the 2010 estimate or current analysis.
Generally, escalation of the various cost components in a decommissioning analysis (with the exception of those costs associated with radioactive waste disposal),
follows "standard" cost indices. However, such indices can only be applied successfully to a static model, i.e., where the bases against which the indices are applied have not undergone significant change. In the period between the last two analyses (the 2004 and 2010 financial years), new cost elements have been added and older cost elements revised. With this in mind, the following discussion encompasses the major areas of difference between the two estimates.
In 2004, the estimate to promptly decommission St. Lucie was estimated at approximately $1,037.6 million (in 2004 dollars). The comparable cost in 2010 is
$1,478.8 million (in 2010 dollars). This represents a 43% increase in the overall cost. Major areas of change in the two estimates are shown in Table 1.
The decommissioning scope of the current cost estimate has not significantly changed from that evaluated presented in 2004. However, the current estimate delays the completion of the spent fuel transfer process by approximately 13 years.
This was done in response to the continuing lack of progress by the Department of Energy (DOE) in developing a geologic repository (or interim facility) for the spent fuel. The longer schedule (primarily in the post-decommissioning dry spent fuel storage period), increased the period-dependent costs (e.g., staffing, fees, insurance, and other site operating costs), reported for spent fuel management.
The following cost element discussions are arranged in decreasing order of overall financial impact between the estimates.

: 1. Program Management The organization identified to oversee the decommissioning project and manage the day-to-day activities is similar in structure to the operating organization, although much reduced in size.
The cost category includes several contributors:
* Plant Staff: comprised of the decision-making individuals at the site, administrative, secretarial and/or clerical support, plant management responsible for the facility's operation, maintenance, as well as compliance with the existing operating license and technical specifications during the initial preparation phase, quality assurance and quality surveillance, engineering support, planning and cost control personnel, health physics and radiation protection, industrial safety, waste management, procurement, document control, and field superintendents for work force direction
* Engineering: supplemental workforce employed in the preparation stages to support the reconfiguration of the plant for decommissioning, develop specifications, procedures and work packages for both in-house and subcontracted activities, and perform related studies and supporting analyses
       " Security: personnel comprising the on-site, plant security force including surveillance personnel, access/egress control and processing personnel, a rapid response contingent, training and supervisory personnel
* Decommissioning Operations Contractor (DOC): organization contracted to manage the execution of the decontamination and dismantling activities including direct supervision of trades and oversight of subcontractors engaged in specialty activities such as reactor vessel segmentation Table 2 provides a comparison of the peak staffing levels for each decommissioning period and corresponding cost per month. Staffing levels are relatively consistent for the major decommissioning periods with alterations in the 2010 organization resulting in a slight decrease in personnel. Re-evaluation of the site restoration phase (based upon industry experience) resulted in a greater change (decrease) in supervisory/
management personnel.
Exclusive of the adjustments to the organization and general increase in wages and benefits over the six year period, two changes in the modeling TLG Services, Inc.

St. Lucie Nuclear Plant, Units I and 2                      Document F02-1630-003, Rev. 0 ComparisonReport 2004 - 2010                                                Page 3 of 15 assumptions combined to contribute to the $152.7 million increase in the cost of program management: a longer schedule and a larger security force.
The length of the decommissioning schedule (from the cessation of operations to the termination of the site licenses) in the 2010 cost model is approximately 13 years longer than in 2004 (Table 3). This increase is primarily in the post-decommissioning dry spent fuel storage duration (discussed below). This increase not only impacted plant staff and security costs, but other site operating costs as well.
In January 2007, the NRC approved a final rule that enhanced its security regulations governing the design basis threat (DBT). This rule imposed security requirements similar to those previously imposed by the Commission's April 29, 2003, DBT Orders. However, the new rule also modified and enhanced the DBT based on experience and insights gained by the Commission during implementation of the Orders, and extensive consideration of the factors specified in the Energy Policy Act of 2005.
Consequently, based upon the industry's response to the NRC's rulemaking, the security cost model for decommissioning was adjusted to increase the size of the security force (Table 4). The cost impact due to the adjustment was compounded by the lengthening of the spent fuel storage period and the increased cost of the security force in the 2010 estimate.
: 2.      Spent Fuel Management (ISFSI Related)
For purposes of generating a comprehensive post-shutdown cost, the cost to manage the spent fuel generated over the operating life of St. Lucie was included within the decommissioning estimate (a NRC requirement) until such time that the DOE can complete the transfer of the assemblies off-site.
The current (2010) analysis assumes that the DOE will begin the process of removing spent fuel from the St. Lucie site in 2032 (based upon a 2030 industry-wide start date). This is 15 years later than the 2015 date assumed in 2004. The delay is due several factors including DOE's delay in submitting a license application to the NRC for construction of a permanent repository and more recent efforts by the current administration to eliminate funding for the project.
As a result of the delay, the physical infrastructure for on-site storage of spent fuel has been expanded to permit continued operations. It is expected that the current storage facilities will need to be expanded/augmented to permit decommissioning operations to proceed. The impact of the delay can be seen in the variables listed in Table 5; less fuel shipped directly to the TLG Services, Inc.

As indicated by the line "maximum number of HSMs on ISFSI," the size of the on-site fuel storage facility required to support decommissioning is more than double that envisioned in 2004.
: 3. Low-Level Radioactive Waste Disposal Consistent with the 2004 cost estimating model regarding waste disposal, the current cost model assumes that the low-level radioactive waste requiring controlled disposal is sent to EnergySolutions' facility in Clive, Utah.
While the previous estimate was based upon negotiated rates, the current estimate reflects the lower rates afforded by the "Life of Plant Disposal Agreement" entered into by FPL with EnergySolutions. With the volume of containerized waste and bulk debris from the decontamination and dismantling of the plant systems and structures, classified as "Class A" material (in accordance with 10 CFR &sect;61.55), relatively unchanged between the estimates, the cost to dispose of plant systems and structures decreased in the 2010 estimate. This savings was off-set by an additional volume of contaminated soil from the east settling pond, remediation of the storm drain system and disposition of the contaminated discharge canal dredge spoils pile. The volume added in the 2010 estimate is shown in Table 6.
The additional volume (approximately 2 million cubic feet) negated any savings from the lower rates and resulted in a $29.1 million dollar increase in the waste disposal cost category.
: 4. Removal Contract labor is used to decontaminate, remove, and package the plant inventory, as well as to support the dismantling and demolition of the physical structures. The dismantling process is labor-intensive and the cost model assumes that a common laborer performs a majority of the required tasks, with support from the various skilled trades. Wage rates for the laborer and craftsman increased approximately 21% and 22% respectively over the six year period, as shown in Table 7. The rate increases is consistent with the overall increase in the "Removal" cost shown in Table 1.
: 5. Insurance and Regulatory Fees Nuclear and property insurance is maintained throughout the active decommissioning phase. Current operating premiums are reduced TLG Services, Inc.

St. Lucie NuclearPlant, Units I and 2                        Document F02-1630-003, Rev. 0 Comparison Report 2004 - 2010                                                    Page 5 of 15 throughout the active decommissioning phase based upon the guidance and the limits for coverage defined in the NRC's proposed rulemaking "Financial Protection Requirements for Permanently Shutdown Nuclear Power Reactors." Therefore any change in the cost identified for insurance between the two estimates is due to a corresponding change in the starting premiums.
As shown below, the starting (operating) premium for property insurance increased significantly, as compared to that for liability in the 2010 estimate.
NRC fees are associated with the Part 50 operating license(s) and for the oversight and regulatory review anticipated (based upon industry experience) for a decommissiohing project. As shown below, the annual licensing cost has decreased over the past six years, but the hourly rate increased.
Emergency planning fees are included while spent fuel remains on site.
FEMA fees are discontinued shortly after the cessation of operations and defueling. However, state fees are applied until such time that the fuel has been removed from the site. The state fees increased significantly in the 2010 estimate.

: 6. Transportation It was assumed in both the 2004 and 2010 cost models that the low-level radioactive waste requiring controlled disposal would be sent to EnergySolutions' burial facility in Clive, Utah. A portion of the increase in transportation costs is due to a combination of higher tariffs and fuel surcharges. However, the principal contributor to the increase (accounting for TLG Services, Inc.

St. Lucie NuclearPlant, Units 1 and 2                       Document F02-1630-003, Rev. 0 ComparisonReport 2004 - 2010                                                 Page 6 of 15 approximately half of the total increase) is the additional cost associated with the transport of approximately 2 million cubic feet of contaminated soil for controlled disposal in the 2010 estimate.
: 7. Energy Energy costs are included for critical plant systems, temporary power, offices and other facilities housing site personnel, security and other site services.
The increase in energy costs in the 2010 estimate is a direct result of the purchase power rate increasing from $.043 per kilowatt hour in 2004 to $.117 per kilowatt hour in 2010.
: 8. Packaging There are several factors contributing to increased packaging costs. Primary areas of increase were in the costs for the reactor vessel internals, specifically the GTCC material that is packaged in the same containers used for spent fuel (dry shielded canisters and horizontal storage modules). The number of GTCC canisters increased in the 2010 cost model due to the addition of highly-activated material currently stored in the spent fuel pools. Also contributing the higher 2010 cost was the packaging associated the disposal of 2 million cubic feet of contaminated soil.
: 9. Property Taxes Property taxes continue to be included as a site operating cost during decommissioning. The 2004 estimate assumed that taxes would continue to be assessed on existing plant structures and equipment until they were physically removed. By comparison, the 2010 estimate assumes no significant value for the site structures and includes only a value on the land (protected area) during active decommissioning and only on ISFSI footprint thereafter.
Property taxes decreased $9.5 million in the 2010 estimate (Table 1),
primarily due to the change in assumptions on how the tax would be assessed.
: 10. Off-Site Waste Processing Off-site waste processing rates decreased slightly over the six year period.
The savings was offset by additional material being designated for processing (recycling) in the 2010 estimate (from the steam generators, turbines and condensers) as shown in Table 6.

: 11. Site Characterization and License Termination Surveys Survey costs increased commensurate with the increase in craft labor shown in Table 7.
: 12. Spent Fuel Pool Isolation The isolation cost includes the engineering, facility modifications, and the capital improvements necessary to segregate the pool areas and reduce the protected boundary, so that decommissioning operations can proceed expeditiously. The 2010 value for this cost element represents an annual increase of 3% over the six year period, consistent with increase in the cost of engineering (personnel salaries) and craft labor.
: 13. Decontamination An increase in labor-related costs (approximately 18%), mitigated by a smaller increase (8%) in the costs of equipment and materials, resulted in an overall 13% increase associated with the decontamination activity.
The volume of the primary system components (reactor vessel, steam generators, reactor coolant pumps, etc.) is used to estimate the cost to decontaminate the system. Based on past experience, the volume of wetted surfaces was adjusted in the 2010 estimate to exclude filling the reactor vessel. As a result, the volume decreased from approximately 80,000 gallons in the 2004 model to 26,000 gallons in the 2010 model. This impacted (lowered) the cost of the chemicals used to decontaminate the primary loop as well as the processing costs (filters and resin).
: 14. Fixed Overhead Overhead charges were updated from the 2004 estimate, resulting in a $1.26 million dollar increase. The annual site cost for St. Lucie increased from approximately $730 thousand in 2004 to $836 thousand in 2010. The increase was applied across the active decommissioning periods.

The value is not indicative of the majority of the cost drivers, but skewed with the large increase in spent fuel management costs. (The spent fuel management increase is a direct result of the DOE's non-performance rather than changes in the cost estimating methodology.)
As shown in Table 1, license termination costs (or the cost associated with "decommissioning" as defined by the NRC in its financial assurance regulations) increased 34% over the six year period (for an average annual increase of 5.1%). As discussed in the previous narrative, cost drivers for the increase included a larger waste volume designated for controlled disposal in the 2010 cost model (2 million cubic feet of contaminated soil and additional highly-activated material requiring geologic isolation comparable to the spent fuel), additional security and higher site operating costs (e.g., energy, insurance, and emergency planning fees).
The spent fuel management category contains costs associated with the interim storage of fuel at the St. Lucie site until such time that the DOE is able to take possession. The costs estimated for this activity increased 97% from 2004 and 2010.
While increases were realized in hardware and labor costs (for onsite storage and transfer of the fuel assemblies), the underlying reason for the increase was DOE's non-performance in meeting its contractual commitments. As a result, the assumed start date for fuel acceptance (for commercial generators) was delayed an additional 15 years for the 2010 estimate (from 2015 to 2030).[3] The outcome was a 13 year longer period of ISFSI operations and significantly more fuel in storage at the St.
Lucie site. An additional $163 million was added to the 2010 estimate as a result.
If the 2010 spent fuel management costs are reduced by the $231.5 million in estimated DOE reimbursements (identified in Tables 3.7 and 3.8 of the 2010 cost study), the 2010 result would be a 40.7% decrease from the spent fuel management costs reported in 2004 (from approximately $168.1 million in 2004 to $99.6 million in 2010).
Site restoration (used to capture                   costs associated with the dismantling and demolition of buildings and facilities               demonstrated 'to be free from contamination) showed only a modest increase (10%)                 over the six years. This was primarily a result of streamlining the organizations                    (plant and contractor) managing the site activities.
3   FPL's position is that the DOE has a contractual obligation to accept St. Lucie's fuel far earlier than the projections used as an estimating basis. No assumption used in the decommissioning study should be interpreted to be inconsistent with this claim.

==SUMMARY==

Florida Power & Light Company                                                Executive Summary 2010 Nuclear Decommissioning Study                                           Page 1 of 3 Overview FPL's 2010 Nuclear Decommissioning Study results are based on estimates and assumptions that follow Nuclear Regulatory Commission (NRC) requirements and industry guidelines for the development of the costs to remove and dismantle nuclear power plants decades into the future. Funds are maintained and interest reinvested in the decommissioning trusts as required by the NRC, Internal Revenue Service, Federal Energy Regulatory Commission and Florida Public Service Commission (FPSC). Under federal law, these funds may only be used for nuclear decommissioning, are not available for any other use and do not earn a return or profit for FPL; The study is essentially a snapshot, which shows that based on current assumptions FPL's nuclear decommissioning trust funds are appropriately funded and demonstrate that, despite downturns in the market, these funds are helping protect customers from potential future cost increases. Compared to 2005, the currently calculated funding position has improved primarily because of a decrease in the assumed escalation rate for future decommissioning costs, in addition to a reduction in the estimated nominal cost of decommissioning resulting from a settlement with the Department of Energy (DOE). FPL customers have not contributed to the decommissioning trusts since 2005, and the study confirms that, as of Dec. 31, 2010, the trusts continue to be adequately funded without FPL customer contributions.
Decommissioning studies represent the aggregation of numerous estimates for activities and costs that will not be incurred for at least 22 years. As such, they are highly dependent upon input assumptions that can and will change over time, such that future funding positions could differ substantially from today's position. Historical costs and investment returns over the last five years have actually had a negative impact on the funding position, but adjustments to assumptions regarding events that will occur far in the future drive the net improvement. The current assumed escalation rate is 1.6 percent lower than in the 2005 study, and the impact of this change is substantially greater than the entire difference in funding positions between 2005 and 2010, reaffirming the importance of maintaining adequate funding. For this reason, the FPSC and FPL should continue to review these studies on the scheduled basis to ensure that adequate funds are available to decommission FPL's nuclear plants at the appropriate time.
2010 Study Approach The information contained in this 2010 Decommissioning Study is presented in compliance with Rule 25-6.04365, Florida Administrative Code, and prior Commission Orders. FPL contracted TLG Services, Inc. (TLG), the leading provider of these services to the U.S. nuclear industry, to prepare its 2010 site-specific nuclear decommissioning cost analysis and comparison reports, which are estimated based on NRC requirements, industry guidelines, and prior experience.
TLG includes the most up to date actual decommissioning information available to ensure the methodology used to prepare the cost analysis is reasonable.
FPL selected a DECON (immediate dismantlement) decommissioning option for its units. The DECON method provides not only a lower cost, but also enables a coordinated sequence of decommissioning events, which allows for a one-time mobilization of contractor personnel and equipment. FPL's choice of the DECON method is consistent with the method in prior studies approved by the Commission for purposes of determining FPL's appropriate accrual and funding requirements.

Florida Power & Light Company                                               Executive Summary 2010 Nuclear Decommissioning Study                                          Page 2 of 3 Escalation Rate The 2010 Decommissioning Study assumes that future decommissioning costs grow at an average rate of approximately 3.0 percent per year. In contrast, the 2005 study assumed an average escalation rate of 4.6 percent. FPL notes that the current escalation rates are below any typical range due to the current macro economic market conditions that have reduced escalation factors to near all time lows. While FPL believes that the current escalation rates are reasonable for the purpose of the 2010 Decommissioning Study, it should be noted that subsequent changes in the assumed escalation rate are likely to be increases, which would result in higher projected future decommissioning costs.
Spent Fuel Management Consistent with prior studies and assumptions approved by the Commission, the decommissioning cost estimates include the cost associated with interim storage of spent nuclear fuel.(SNF) on site until such time the DOE is able to remove SNF from the site.
Subsequent to the 2005 study, in 2009, FPL executed a Settlement Agreement with the U.S.
Government that resolved FPL's lawsuit for damages resulting from a DOE delay in commencement of disposal of SNF. The Settlement Agreement requires the Government to make payments to FPL to cover the cost incurred for managing and storing SNF that would not have been incurred but for DOE's delay in SNF disposal. As such and for purposes of this study, the DOE is expected to make payments to FPL to cover spent fuel management costs incurred by FPL prior to 2062, which is the date FPL currently projects that the DOE will meet its obligation to begin disposal of SNF. For purposes of the funding and accrual analysis contained in this study, the 2010 decommissioning costs have been reduced significantly to reflect the reimbursement by the Government of SNF management costs incurred during the decommissioning period. This is the first time expected Government reimbursements have been factored in to FPL's funding analyses and nuclear decommissioning studies. The ultimate timing and amount of reimbursements will depend on many factors, including but not limited to, the
 -DOE's ability to receive SNF and the Government's compliance with the terms of the Settlement Agreement. Some state jurisdictions do not allow utilities to include SNF settlements in their decommissioning. funding analyses due to the concern that reimbursements may not be guaranteed and may bias the result. FPL believes that the recognition of the SNF reimbursements should be included based on the fact that the Settlement Agreement is a
-binding legal agreement on the Government and FPL has successfully received SNF reimbursements pursuant to the Settlement Agreement.
Fund Earnings Rate Since 2005, FPL customers have not made contributions to the nuclear decommissioning trusts, but an adequate funding level has been maintained, as indicated in the estimates included in the 2010 study. This is despite investment returns totaling $133 million less than estimated in the 2005 study. FPL's current investment strategy for its nuclear decommissioning funds is largely consistent with its 2005 study. The economy remains weak; therefore, future investment results are uncertain.

Florida Power & Light Company                                               Executive Summary 2010 Nuclear Decommissioning Study                                          Page 3 of 3 Chan-qes from 2005 to 2010 The changes in actual cost and actual returns since 2005 have reduced the funded status of FPL's four nuclear units by more than $195 million as of Dec. 31, 2010. These reductions have been offset primarily by reductions in assumed escalation factors for future decommissioning costs and, to a lesser extent, government reimbursements pursuant to the SNF settlement. As discussed above, the funding status is highly dependent upon the assumed escalation rates, which are currently assumed to be at near all-time lows and could increase significantly in the future.
Sensitivities FPL believes the assumptions used in the 2010 funding analyses are based on the best information available at the time the study was prepared, and represents a reasonable outcome.
However, due to the number of assumptions that must be made and the length of time before decommissioning will actually begin, it is important to understand a range of results can be produced using other assumptions. The following are examples of sensitivities that provide a high degree of uncertainty:
* Timing and amount of future DOE reimbursement under the SNF settlement (represents approximately 88 percent of the change in the funded position)
* Lower than anticipated fund earnings as a result of future market downturns a  Increase in the escalation of burial costs
* Increase in cost of nuclear decommissioning activities Conclusion The 2010 Decommissioning Study indicates that the trusts are currently at an adequate funding level given current assumptions and projections. These trusts are necessary so FPL's customers are adequately protected from further cost increases when the time comes to decommission FPL's nuclear plant. FPL has earned its customers trust by using careful, prudent investment strategies in all facets of its business including the management of its nuclear decommissioning trusts. Despite recent volatile markets, the funds remain secure. As a result, FPL's current annual expense accrual requirements for decommissioning costs presented in this study support a zero accrual and funding requirement as of Dec. 31, 2010.
In addition, as required by the Commission in Order Nos. FPSC-02-0055-PAA-EI and FPSC 0153-FOF-EI, FPL has updated its estimates for End of Life Nuclear Fuel Last Core and End of Life Materials and Supplies Inventory balances. This information is provided for informational purposes with this study. FPL is not requesting a change in accruals at this time. Rather, FPL believes that the results of these updated values for End of Life Nuclear Fuel Last Core and End of Life Materials and Supplies should be addressed in FPL's next base rate proceeding and that the appropriate changes in accruals, if any, should be made at that time.

Decommissioning Methods For purposes of this analysis, decommissioning is defined as the activity whereby nuclear facilities are removed safely from service and residual radioactivity is reduced to a level that permits release of the property for unrestricted use and termination of the operating license granted under Title 10 CFR Part 50. Decommissioning also includes the dismantlement, disposal and site restoration activities associated with the non-contaminated portion of the facilities. These activities are not required for termination of the operating license, but are required to address other non-radiological requirements associated with the release of the site.
The Nuclear Regulatory Commission (NRC) has defined three acceptable decommissioning methods: Prompt Removal/Dismantling (DECON); Safe Storage/Deferred Decontamination (SAFSTOR); and Entombment (ENTOMB). The study utilizes the NRC terminology, but also includes the additional activities required to accommodate the non-contaminated portion of the facilities.
The DECON and SAFSTOR alternatives were both examined and are presented in the (TLG) Decommissioning Cost Analysis section (Section 10) of this filing. The ENTOMB alternative was not considered, because it is considered impractical for a facility which generates significant amounts of long-lived radioactive material due to neutron activation.
FPL selected the DECON decommissioning option for Turkey Point Units 3 and 4. The DECON method provides not only a lower cost, but also enables a sequence of events, which allows for a one-time mobilization of contractor personnel and equipment. This method is consistent with the method in prior studies approved by the Commission for purposes of determining the appropriate accrual and funding requirements.

Beginning in 1983 FPL began making contributions, on a net of tax basis, to an externally funded reserve. In 1986, the Treasury Department issued temporary regulations under Internal Revenue Code Section 468A relating to the deductibility of contributions made to a qualified decommissioning fund. These regulations, which were finalized in March of 1988, provide for an annual election by the taxpayer to make tax-deductible contributions to a qualified nuclear decommissioning fund. Qualified nuclear decommissioning funds have been established by FPL for each of the four nuclear units. FPL elected to make contributions to the qualified funds, to the maximum allowed, for the years 1984 through 1987, 1992 through 2004 and for the year to date period ended August 31, 2005. Per the Stipulation and Settlement Agreement approved by the Commission in FPSC Order No. FPSC-05-0902-S-EI, FPL suspended accruals effective September 1, 2005, and as such, no additional contributions to the funds have been made subsequent to that date.

Florida Power & Light Company 2010 Decommissioning Study Turkey Point Nuclear Units Assumptions.
Page 4 of 10 The funding analysis presented in Sections G of this study indicates that no additional contributions to the qualified and nonqualified funds are projected to be required through the remainder of the funding period that ends with the expiration of the unit's operating license. Only the after-tax earnings of the trust fund investments are assumed to continue to be reinvested and accumulated in the respective funds. Future decommissioning expenditures are assumed to be distributed from the qualified and nonqualified funds in proportion to the balance accumulated at the time of expenditure.
Funding Period The funding period, to the extent funding is required, is that period over which revenues are collected from ratepayers for purposes of decommissioning the Turkey Point Units.
Funding periods for both units end on the last day of the month preceding the month in which the operating license for the unit is due to expire. The operating license expiration dates for the Turkey Point units are as follows.
* Turkey Point Unit No. 3 - July 19, 2032
* Turkey Point Unit No. 4 - April 10, 2033 Based on the results of the funding analysis presented in Support Schedule G, no additional funding is required at this time.
Fund Earnings Rate For purposes of this 2010 study update and funding analysis, the projected annual funds earnings rate, net of taxes and all other administrative costs charged to the trust funds, for Units 3 and 4 qualified and nonqualified fund investments, is assumed to be 3.9%. This assumption is based on a projected real long-term, after tax and net of fees, earnings rate of 1.9% plus an estimated long term average inflation rate of 2.0%. The long-term, after tax and net of fees earnings rate reflects the projection of continued adequacy of the funds and assumes a conservative investment strategy where the funds are moved to 100% fixed income prior to the first year of decommissioning and a more conservative all bonds & cash asset mix in the final years of decommissioning. FPL recognizes that over the long-term period there will likely be periods when the earned return may be greater or less than the assumed 3.9%. Consistent with prior Commission practice and Rule 25-6.04365 (FAC) the assumptions presented in this 2010 study will be reviewed and updated as appropriate "at least once every five years".

Florida Power & Light Company 2010 Decommissioning Study Turkey Point Nuclear Units Assumptions Page 5 of 10 The annual rates of change in CPI were taken from "The U. S. Economy, The 30 - Year Focus, Third - Quarter 2010", published by Global Insight.
Escalation Rate The annual escalation rates used to estimate total future dismantlement costs from 2010 through the final year of decommissioning are as follows:
Average Annual Escalation Rate Turkey Point Unit No. 3                         2.95%
Turkey Point Unit No. 4                         2.95%
The above rates were derived by applying separate inflation indices to each of the major cost components of Labor, Materials and Equipment, Transportation, Burial, and Other.
Cost Component                           Inflation Index Labor                            Compensation per Hour Materials and Equip.              PPI - Intermediate Materials, Supplies, and Components Shipping                          GDP Deflator-Transportation Burial                             FPL Analysis & CPI Other                                    GDP (Implicit)
For purposes of this 2010 study update, the inflation indices were obtained from The U.S.
Economy, The 30 - Year Focus, Third - Quarter 2010", published by Global Insight except for the burial index.
The burial cost estimates are assumed to escalate at an average annual rate of 3%. This is a reduction from the 6.6% rate assumed in the 2005 study. Since the 2005 study was prepared, FPL has signed an agreement with Energy Solutions which provides for the long-term disposal of Class A waste generated during decommissioning. As such, burial

Florida Power & Light Company 2010 Decommissioning Study Turkey Point Nuclear Units Assumptions Page 6 of 10 costs for disposal of Class A waste is estimated based on the Energy Solution agreement.
Escalation of pricing under this agreement is tied to changes in the Consumer Price Index (CPI). In addition, the cost estimates for processed/conditioned (at off-site recycling center) disposal of Class A waste is assumed to be at a competitive rate comparable to the Energy Solutions pricing. Burial cost rates for Class B and Class C waste, not covered by the Energy Solutions Agreement, are less certain and based on rates equivalent to Barnwell published rates. The escalation rate applicable to Class B and C waste is assumed to be 6.6% which approximates the historical rate of change in published Barnwell rates. The resulting annual escalation rate of 3% applied to burial costs is a weighted rate based on Class A waste (approx. 68% of total burial costs) at the estimated long-term CPI rate of 2% and Class B and C waste (approx. 32% of total burial costs) estimated at 6.6%.
For a more detail calculation of the overall weighted average escalation rate and annual rate of change for each component please refer to Support Schedule G ("Inflation and Funding Analysis").
FPSC Jurisdictional Factor The factor applicable to both units is 98.8182%.
Fund Balances Estimated/actual fund balances (qualified and nonqualified) at December 31, 2010(a) for each of the two Turkey Point Units are as Follows:
                                                         $(000)
Qualified              Nonqualified Unit No. 3                   $339,626,000           $151,912,000 Unit No. 4                   $389,183,000           $162,754,000 (a) Excluding unrealized market gains/losses.
See support Schedule C ("Projected Fund and Reserve Balances") for detail composition and adjustments to the qualified and nonqualified fund balances.

Florida Power & Light Company 2010 Decommissioning Study Turkey Point Nuclear Units Assumptions Page 7 of 10 End of Life Materials and Supplies Inventory Values The decommissioning cost estimates contained in the TLG Decommissioning Cost Analysis section of this study and in the funding analysis contained in Support Schedule G of this filing do not take into consideration the unrecovered value of any Materials and Supplies Inventories that will ultimately exist at the site following shut down of both units.
Both FPL and this Commission have previously recognized that there will be a level of inventories that will remain at the end of life of Unit No. 4, the last unit to reach end of license, which must be recovered prior to the end of site operations. These inventories are unique and will have little value other than scrap value when the units are decommissioned. In Order No. FPSC-02-0055-PAA-EI, the Commission authorized FPL to begin recording the amortization of estimated end of life materials and supplies costs as a base rate fuel expense with a credit to a separate (unfunded) sub-account of Reserve Account 228. Additionally, the Commission directed the Company to address the costs associated with the materials and supplies in subsequent decommissioning studies so that the related annual accruals can be revised, if warranted. The annual expense/reserve accruals associated with End of Life Inventories are being accounted for, as directed by the Commission, in a separate (unfunded) sub-account of Reserve Account 228.
As provided in Support Schedule E of this study, the Materials and Supplies inventory balance, less estimated salvage, that is anticipated to remain at the end of life of Unit No.
4, the last unit to reach end of license, is projected to be $31,353,707. The actual balance accrued as of 12/31/10 is $10,483,288. FPL is not requesting a change in accruals at this time. Rather, FPL believes that the results of these updated values for End of Life Materials and Supplies should be addressed in FPL's next base rate proceeding and the appropriate changes in accruals, if any, be made at that time.
End of Life Last Core Nuclear Fuel Values FPL recognizes that there will be unburned fuel that will remain in the fuel assemblies at the end of the last operating cycle of each nuclear unit when it ceases operation. In Docket No 981246-El the Commission found that the cost associated with the Last Core were costs that should be considered a base rate future obligation and that amortization of this obligation over the remaining life span of each nuclear unit ratably allocates the costs to those customers receiving the benefit of the nuclear generation and avoids a burdensome expense at the time of unit shut down. In Order No. FPSC-002-0055-PAA-EI

Florida Power & Light Company 2010 Decommissioning Study Turkey Point Nuclear Units Assumptions Page 8 of 10 the Commission authorized FPL to begin recording the amortization of estimated Last Core costs as a base rate fuel expense with a credit to a separate (unfunded) sub-account of Reserve Account 228. Additionally, the Commission directed the Company to address the costs associated with the Last Core in subsequent decommissioning studies so that the related annual accruals can be revised, if warranted. The annual expense/reserve accruals associated with End of Life Nuclear Fuel Last Core values are accounted for, as directed by the Commission, in a separate (unfunded) sub-account of Reserve Account 228.
As provided in Support Schedule F of this study, the estimated cost of unburned fuel remaining in the reactor at the end of life (end of license) for each unit is:
        " Unit No. 3                                   $78,900,000
        " Unit No. 4                                   $78,700,000 The actual balances accrued as of 12/31/10 are:
* Unit No. 3                                 $13,716,005
* Unit No. 4                                 $9,346,107 FPL is not requesting a change in accruals at this time. Rather, FPL believes that the results of these updated values for End of Life Nuclear Fuel Last Core should be addressed in FPL's next base rate proceeding and the appropriate changes in accruals, if any, be made at that time.
Spent Nuclear Fuel Storage The Nuclear Waste Policy Act of 1982 assigns to the Federal Government responsibility to provide for the permanent disposal of spent nuclear fuel (SNF) and high-level radioactive waste (HLW), and committed the DOE to begin acceptance of SNF/HLW not later than January 31, 1998 under terms of its Standard Disposal Contracts with waste generators.
The DOE has not yet provided for SNF storage and is not accepting SNF as committed to under the contract.
In Docket No. 941350-El, and No. 981246-El, the FPSC recognized the impact on the decommissioning process and the potential costs of on-site dry fuel storage resulting from the inability of the DOE to provide for the timely removal of SNF. In Order Nos. PSC 1531-FOF-EI and PSC-02-0055-PAA-EI, the FPSC specifically approved the inclusion of

Florida Power & Light Company 2010 Decommissioning Study Turkey Point Nuclear Units Assumptions Page 9 of 10 costs associated with the dry storage of spent nuclear fuel following the end of each units operating license which were considered necessary to accommodate the timely decommissioning of each unit.
Consistent with the Commission's prior findings, this updated 2010 decommissioning study includes the costs relating to the construction, operation, and dismantlement of an on-site independent spent fuel storage installation (ISFSI) that is required to accommodate the timely decommissioning of the Turkey Point units. The potential cost impact of extended spent fuel storage that will exist subsequent to the license expiration of the Turkey Point nuclear units is presented in (Section 10) the 2010 Decommissioning Cost Analysis for the Turkey Point Plant. The decommissioning cost estimates included in this filing are based on the TLG prepared Decommissioning Cost Analysis for the Turkey Point Plant, Units 3 and 4 dated December, 2010.
In addition, FPL and certain nuclear plant joint owners signed a settlement agreement (spent fuel settlement agreement) with the U.S. Government in 2009 agreeing to dismiss with prejudice lawsuits filed against the U.S. Government seeking damages caused by the DOE's failure to dispose of spent nuclear fuel from FPL's nuclear plants. As such, the DOE is expected to make payments to FPL to cover the costs incurred for managing and storing the spent fuel that it would not have incurred but for DOE's delay in performance.
Below are the Turkey Point estimated costs of Decommissioning expected to be recovered from the DOE as provided by FPL's consultant, TLG Services, Inc. in 2010 dollars.

==SUMMARY==

This report presents estimates of the cost to decommission the Turkey Point Nuclear Plant, Units 3 and 4 (Turkey Point). The analysis relies upon site-specific, technical information from an evaluation prepared in 2005,[1] updated to reflect current assumptions pertaining to the disposition of the two nuclear units and relevant industry experience in undertaking such projects. The station inventory, the basis for the decontamination and dismantling requirements and cost, and the decommissioning waste streams, were reviewed for this analysis. The current estimates reflect any substantive changes over the five year period to the configuration of the plant or site that would impact decommissioning.
The current estimates are designed to provide Florida Power & Light Company (FPL) with sufficient information to assess its financial obligations, as they pertain to the decommissioning of the nuclear station. The estimates do not reflect the actual plan to decommission all aspects of Turkey Point; the plan may differ from the assumptions made in the cost estimates based on facts that exist at the time of the decommissioning activity.
The primary goal of the decommissioning is the removal and disposal of the contaminated systems and structures so that the operating licenses for the nuclear units can be terminated. The analysis recognizes that spent fuel will be stored at the site in the wet storage pools and/or in an independent spent fuel storage installation (ISFSI) until such time that it can be transferred to the U.S. Department of Energy (DOE). Consequently, the estimates also include those costs to manage and subsequently decommission these interim storage facilities.
The currently projected cost to promptly decommission the station (DECON alternative), manage the spent fuel, and restore the site, is estimated at $1,386.2 million, as reported in 2010 dollars. The cost to defer decommissioning by placing the unit in safe-storage (SAFSTOR alternative) for approximately 50 years is estimated at $1,770.0 million, as reported in 2010 dollars. A portion of the costs associated with spent fuel management is considered to be recoverable from the DOE, as described later in this section and in more detail in Section 3.
The estimates are based on numerous fundamental assumptions, including regulatory requirements, low-level radioactive waste disposal practices, high-level radioactive waste management options, project contingencies, and site restoration requirements. The estimates incorporate a minimum cooling period for the spent 1   "Decommissioning Cost Analysis for the Turkey Point Nuclear Plant, Units 3 and 4," Document F02-1512-003, Rev. 0, TLG Services, Inc., October 2005 TLG Services,Inc.

Once sufficiently cooled the spent fuel is transferred to the DOE or to the ISFSI for interim storage. The prompt decommissioning scenario assumes that the dismantling of Unit 3 will be sequenced with the similar activities at Unit 4. The estimates also include the dismantling of site structures and non-essential facilities and the limited restoration of the site.
Alternatives and Regulations The ultimate objective of the decommissioning process is to reduce the inventory of contaminated and activated material so that the license can be terminated. The Nuclear Regulatory Commission (NRC) provided initial decommissioning requirements in its rule adopted on June 27, 1988.[2] In this rule, the NRC set forth financial criteria for decommissioning licensed nuclear power facilities. The regulations addressed planning needs, timing, funding methods, and environmental review requirements for decommissioning. The rule also defined three decommissioning alternatives as being acceptable to the NRC: DECON, SAFSTOR, and ENTOMB.
DECON is defined as "the alternative in which the equipment, structures, and portions of a facility and site containing radioactive contaminants are removed or decontaminated to a level that permits the property to be released for unrestricted use shortly after cessation of operations."[3]
SAFSTOR is defined as "the alternative in which the nuclear facility is placed and maintained in a condition that allows the nuclear facility to be safely     stored      and       subsequently          decontaminated          (deferred decontamination) to levels that permit release for unrestricted use."[4]
       *Decommissioning is to be completed within 60 years, although longer time periods will be considered when necessary to protect public health and safety.
ENTOMB is defined as "the alternative in which radioactive contaminants are encased in a structurally long-lived material, such as concrete; the entombed structure is appropriately maintained and continued surveillance is carried out until the radioactive material 2   U.S. Code of Federal Regulations, Title 10, Parts 30, 40, 50, 51, 70 and 72 "General Requirements for Decommissioning Nuclear Facilities," Nuclear Regulatory Commission, Federal Register Volume 53, Number 123 (p 24018 et seq.), June 27, 1988 3   Ibid.

The 60-year restriction has limited the practicality for the ENTOMB alternative at commercial reactors that generate significant amounts of long-lived radioactive material. In 1997, the NRC directed its staff to re-evaluate this alternative and identify the technical requirements and regulatory actions that would be necessary for entombment to become a viable    option. The       resulting       evaluation       provided      several recommendations; however, rulemaking has been deferred pending the completion of additional research studies, for example, on engineered barriers.
In 1996, the NRC published revisions to the general requirements for decommissioning nuclear power plants to clarify ambiguities and codify procedures and terminology as a means of enhancing efficiency and uniformity in the decommissioning process.[6 ] The amendments allow for greater public participation and better define the transition process from operations to decommissioning.
Regulatory Guide 1.184, issued in July 2000, further described the methods and procedures acceptable to the NRC staff for implementing the requirements of the 1996 revised rule relating to the initial activities and major phases of the decommissioning process. The costs and schedules presented in this analysis follow the general guidance and processes described in the amended regulations. The format and content of the estimates is also consistent with the recommendations of Regulatory Guide 1.202, issued in February 2005.[7]
Turkey Point Decommissioning Scenarios Two decommissioning scenarios were evaluated for the Turkey Point nuclear units. In both instances a 60-year operating life was assumed. The scenarios selected are representative of alternatives available to the owner and are defined as follows:
: 1.      DECON: The operating licenses for Units 3 and 4 currently expire in July 2032 and April 2033, respectively. The first scenario assumes that decommissioning activities at the two units are sequenced and integrated so as to minimize the total duration of the physical dismantling processes. Any 5  Ibid.

Spent fuel storage operations continue at the site until the transfer of the fuel to the DOE is complete, assumed to be in the year 2072.
: 2.       SAFSTOR: The units are placed into safe-storage shortly after the permanent cessation of operations and defueling. Spent fuel remaining in the spent fuel storage pools after a minimum cooling period is transferred to the ISFSI for interim storage, consistent with the DECON spent fuel management plan.
Decommissioning is deferred beyond the fuel storage period to the maximum extent possible; termination of the licenses would conclude within the required 60-year period. As with the DECON scenario, decommissioning activities at the two units are sequenced and integrated so as to minimize the total duration of the physical dismantling processes.
Methodoloa The methodology used to develop the estimates described within this document follows the basic approach originally presented in the cost estimating guidelines[8I developed by the Atomic Industrial Forum (now Nuclear Energy Institute). This reference describes a unit factor method for determining decommissioning activity costs. The unit factors used in this analysis incorporate site-specific costs and the latest available information on worker productivity in decommissioning.
The estimates also reflect lessons learned from TLG's involvement in the Shippingport Station decommissioning, completed in 1989, and the decommissioning of the Cintichem reactor, hot cells and associated facilities, completed in 1997. In addition, the planning and engineering for the Pathfinder, Shoreham, Rancho Seco, Trojan, Yankee Rowe, Big Rock Point, Maine Yankee, Humboldt Bay-3, Connecticut Yankee and San Onofre-1 nuclear units have provided additional insight into the process, the regulatory aspects, and technical challenges of decommissioning commercial nuclear units.
An activity duration critical path is used to determine the total decommissioning program schedule. The schedule is relied upon in calculating the carrying costs, which include program management, administration, field engineering, equipment rental, and support services, such as quality control and security.

This contingency factor is a nearly universal element in all large-scale construction and demolition projects. It should be noted that contingency, as used in this analysis, does not account for price escalation and inflation in the cost of decommissioning over the remaining operating life of the nuclear units.
Contingency funds are expected to be fully expended throughout the program. As such, inclusion of contingency is necessary to provide assurance that sufficient funding will be available to accomplish the intended tasks.
Low-Level Radioactive Waste Disposal The contaminated and activated material generated in the decontamination and dismantling of a commercial nuclear reactor is classified as low-level (radioactive) waste, although not all of the material is suitable for "shallow-land" disposal. With the passage of the "Low-Level Radioactive Waste Policy Act" in 1980,[1&deg;1 and its Amendments of 1985,[111 the states became ultimately responsible for the disposition of low-level radioactive waste generated within their own borders. However, with the exception of Texas (which has issued a license for a new facility), no new compact facilities have been successfully sited, licensed, and constructed.
In past studies, there were two facilities available to FPL for the disposal of low-level radioactive waste generated by Turkey Point. As of July 1, 2008, however, the facility in Barnwell, South Carolina was closed to generators outside the Atlantic Compact (comprised of the states of Connecticut, New Jersey and South Carolina). This leaves the facility in Clive, Utah, operated by EnergySolutions, as the only currently available destination for low-level radioactive waste requiring controlled disposal, until the construction of Waste Control Specialist's facility in Andrews County, Texas, is complete.

EnergySolutions does not have a license to dispose of the more highly radioactive waste (Classes B and C), for example, generated in the dismantling of the reactor vessel. As a proxy, the disposal cost for this material is based upon the last published rate schedule for non-compact waste for the Barnwell facility, adjusted for escalation of the Atlantic Compact rates.
The dismantling of the components residing closest to the reactor core generates radioactive waste that may be considered unsuitable for shallow-land disposal (i.e.,
low-level radioactive waste with concentrations of radionuclides that exceed the limits established by the NRC for Class C radioactive waste (GTCC)). The Low-Level Radioactive Waste Policy Amendments Act of 1985 assigned the federal government the responsibility for the disposal of this material. The Act also stated that the beneficiaries of the activities resulting in the generation of such radioactive waste bear all reasonable costs of disposing of such waste. However, to date, the federal government has not identified a cost for disposing of GTCC or a schedule for acceptance. For purposes of this estimate, the GTCC radioactive waste has been assumed to be packaged and disposed of as high-level waste, at a cost equivalent to that envisioned for the spent fuel.
For purposes of this analysis, GTCC is packaged in the same canisters that are designated for the disposal of spent fuel (modified for the different waste form). The GTCC material is stored with the spent fuel at the ISFSI in the DECON scenario and shipped at the conclusion of the spent fuel transfer process. GTCC is shipped as it is generated in the SAFSTOR scenario since it occurs after the fuel has been removed from the site.
A significant portion of the waste material generated during decommissioning may only be potentially contaminated by radioactive materials. This waste can be analyzed on site or shipped off site to licensed facilities for further analysis, for processing and/or for conditioning/recovery. Reduction in the volume of low-level radioactive waste requiring disposal in a licensed low-level radioactive waste disposal facility can be accomplished through a variety of methods, including analyses and surveys or decontamination to eliminate the portion of waste that does not require disposal as radioactive waste, compaction, incineration or metal melt. The estimates for Turkey Point reflect the savings from waste recovery/volume reduction.

The NWPA provided that DOE would enter into contracts with utilities in which DOE would promise to take the utilities' spent fuel and high-level radioactive waste and utilities would pay the cost of the disposition services for that material. The NWPA, along with the individual contracts with the utilities, specified that the DOE was to begin accepting spent fuel by January 31, 1998.
Since the original legislation, the DOE has announced several delays in the program schedule. By January 1998, the DOE had failed to accept any spent fuel or high level waste, as required by the NWPA and utility contracts. Delays continue and, as a result, generators have initiated legal action against the DOE in an attempt to obtain compensation for DOE's breach of contract.
A federal appeals court has ruled that DOE's obligation to take possession of spent nuclear fuel is unconditional and cannot be excused either by the absence of a repository or by a claim of unavoidable delay. FPL filed a lawsuit in 2004 claiming damages for DOE's failure to perform as originally prescribed in the standard disposal contract.
On March 31, 2009, FPL executed a Settlement Agreement with the DOE and the Department of Justice (DoJ). In the Agreement, FPL settled the lawsuit in exchange for payments. The payments are intended to cover those costs incurred for managing and storing the spent fuel that it would not have incurred but for DOE's delay in performance.
While the DOE is responsible for the costs incurred until it fulfills its obligation, certain assumptions are needed to assess the financial impact on the identified decommissioning cost scenarios. The assumptions and methodology employed to quantify the expected level of compensation are outlined in Section 3.8.
It is generally necessary that spent fuel be cooled and stored for a minimum period at the generating site prior to transfer. As such, the NRC requires that licensees establish a program to manage and provide funding for the management of all irradiated fuel at the reactor site until title of the fuel is transferred to the Secretary of Energy, pursuant to 10 CFR Part 50.54(bb).[ 141 This funding requirement is fulfilled 13  "Nuclear Waste Policy Act of 1982 and Amendments," DOE's Office of Civilian Radioactive Management, 1982 14 U.S. Code of Federal Regulations, Title 10, Part 50, "Domestic Licensing of Production and Utilization Facilities," Subpart 54 (bb), "Conditions of Licenses" TLG Services, Inc.

The spent fuel pools are expected to contain freshly discharged assemblies (from the most recent refueling cycles) as well as the final reactor core at shutdown. Over the following five and one half years the assemblies are packaged into DOE-provided multi-purpose canisters (MPCs) for transfer to the DOE or dry shielded canisters (DSCs) to the ISFSI for interim storage. It is assumed that this period provides the necessary cooling for the final core to meet the transport and/or storage requirements for decay heat.
DOE's contracts with utilities order the acceptance of spent fuel from utilities based upon the oldest fuel receiving the highest priority.[15] However, DOE contracts provide mechanisms for altering the oldest fuel first allocation scheme, including emergency deliveries, exchanges of allocations amongst utilities and the option of providing priority acceptance from permanently shutdown nuclear reactors.
Because it is unclear how these mechanisms may operate once DOE begins accepting spent fuel from commercial reactors, this study conservatively assumes that DOE will accept spent fuel in an oldest fuel first order. For purposes of this analysis, the first assemblies removed from the Turkey Point site are conservatively assumed to be in 2031. With an estimated, maximum rate of transfer of 3,000 metric tons of uranium (MTU)/year, completion of the removal of fuel from the site is conservatively projected to be in the year 2072. Consequently, costs are included within the estimates for the long-term caretaking of the spent fuel at the Turkey Point site until the year 2072.
FPL's position is that the DOE has a contractual obligation to accept Turkey Point's fuel far earlier than the projections set out above consistent with its contract commitments. No assumption made in this study should be interpreted to be inconsistent with this claim. However, at this time, including the cost of storing spent fuel in this study is the most reasonable approach because it insures the availability of sufficient decommissioning funds at the end of the station's life if, contrary to its contractual obligation, the DOE has not performed earlier.
An ISFSI, which is operated under a general (10 CFR Part 50) license, has been constructed to support management of the spent fuel at the site until the DOE is able to complete the transfer to a federal repository. It is assumed that the ISFSI will be expanded subsequent to plant shutdown to support decommissioning operations. As 15  DOE's acceptance priority ranking is based on the date that spent nuclear fuel was permanently discharged, with the oldest spent nuclear fuel, on an industry-wide basis, given the higher priority. However, the generator has the right to determine which spent nuclear fuel is delivered, provided that it is in compliance with the Standard Contract.

This will allow decommissioning to continue on the nuclear units.
Site Restoration The efficient removal of the contaminated materials at the site may result in damage to many of the site structures. Blasting, coring, drilling, and the other decontamination activities will substantially damage power block structures, potentially weakening the footings and structural supports. Prompt dismantling of site structures (once the facilities are decontaminated) is clearly the most appropriate and cost-effective option. It is unreasonable to anticipate that these structures would be repaired and preserved after the radiological contamination is removed. The cost to dismantle site structures with a work force already mobilized on site is more efficient than if the process is deferred. Site facilities quickly degrade without maintenance, adding additional expense and creating potential hazards to the public and the demolition work force. Consequently, this study assumes that site structures are removed to a nominal depth of three feet-below the local grade level wherever possible. The site is then to be graded and stabilized.
Summary The cost to decommission Turkey Point assumes the removal of all contaminated and activated plant components and structural materials such that the owner may then have unrestricted use of the site with no further requirements for an operating license.
Low-level radioactive waste, other than GTCC waste, is sent to a commercial processor for treatment/conditioning or to a controlled disposal facility.
Decommissioning is accomplished within the 60-year period required by current NRC regulations. In the interim, the spent fuel remains in storage at the site until such time that the transfer to a DOE facility is complete. Once emptied, the fuel storage facilities can be decommissioned (DECON alternative) or placed in storage and decommissioned with the reactor complex (SAFSTOR alternative).
The decommissioning scenarios are described in Section 2. The assumptions are presented in Section 3, along with schedules of annual expenditures. The major cost contributors are identified in Section 6, with detailed activity costs, waste volumes, and associated manpower requirements delineated in Appendices C and D for the DECON and SAFSTOR alternatives. The major cost components are also identified in the cost summary provided at the end of this section.
The cost elements in the estimates are assigned to one of three subcategories: NRC License Termination, Spent Fuel Management, and Site Restoration. The subcategory TLG Services, Inc.

Turkey Point NuclearPlant,Units 3 and 4                       Document F02-1630-002, Rev. 0 DecommissioningCost Analysis                                                Pagexvi of xviii "NRC License Termination" is used to accumulate costs that are consistent with "decommissioning" as defined by the NRC in its financial assurance regulations (i.e.,
10 CFR Part 50.75). The cost reported for this subcategory is generally sufficient to terminate the operating licenses for the two reactors, recognizing that there may be some, additional cost impact from spent fuel management.
The "Spent Fuel Management" subcategory contains costs anticipated to be incurred once the nuclear units cease operation for the off-loading of the pools either directly to the DOE or to the ISFSI for interim storage, and the eventual transfer of fuel from the ISFSI to the DOE. Costs are also included for the operation of the ISFSI until such time that the transfer of all fuel from this facility to an off-site location (e.g., geologic repository or interim facility) is complete. Under the terms of the settlement agreement with the DOE, there are activities and costs identified in the decommissioning cost study that are expected to be eligible for reimbursement (depending upon the timing of the activities). The activities are identified in Section 3.8 and the costs in Tables 3.6 through 3.8.
"Site Restoration" is used to capture costs associated with the dismantling and demolition of buildings and facilities demonstrated to be free from contamination. This includes structures never exposed to radioactive materials, as well as those facilities that have been decontaminated to appropriate levels. Structures are removed to a depth of three feet and backfilled to conform to local grade.
It should be noted that the costs assigned to these subcategories are allocations.
Delegation of cost elements is for the purposes of comparison (e.g., with NRC financial guidelines) or to permit specific financial treatment (e.g., ARO determinations). In reality, there can be considerable interaction between the activities in the three subcategories. For example, an owner may decide to remove non-contaminated structures early in the project to improve access to highly contaminated facilities or plant components. In these instances, the non-contaminated removal costs could be reassigned from Site Restoration to an NRC License Termination support activity.
However, in general, the allocations represent a reasonable accounting of those costs that can be expected to be incurred for the specific subcomponents of the total estimated program cost, if executed as described.
As noted within this document, the estimates were developed and costs are presented in 2010 dollars. As such, the estimates do not reflect the escalation of costs (due to inflationary and market forces) over the remaining operating life of the station or during the decommissioning period.

: 1. INTRODUCTION This report presents estimates of the costs to decommission the Turkey Point Nuclear Plant, Units 3 and 4, (Turkey Point), assuming a 60-year operating life for the selected decommissioning alternatives. The analysis relies upon site-specific, technical information from an earlier evaluation prepared in 2005,[11* updated to reflect current assumptions pertaining to the disposition of the nuclear station and relevant industry experience in undertaking such projects. The station inventory, the basis for the decontamination and dismantling requirements and cost, and the decommissioning waste streams, were reviewed for this analysis. The current estimates reflect any substantive changes over the five year period to the configuration of the plant or site that would impact decommissioning.
The current estimates are designed to provide Florida Power & Light Company (FPL) with sufficient information to assess their financial obligations, as they pertain to the decommissioning of the nuclear station. It is not a detailed engineering document, but a financial analysis prepared in advance of the detailed engineering that will be required to carry out the decommissioning activity.
1.1  OBJECTIVES OF STUDY The objectives of this analysis are to present comprehensive estimates of the costs to decommission Turkey Point, to provide a sequence or schedule for the associated activities, and to identify the waste streams expected from the decontamination and dismantling activities.
For the purposes of this study, the cessation of operations is assumed to be on July 19, 2032 and April 10, 2033 for Units 3 and 4, respectively, based upon the full term of the current operating licenses.
1.2 SITE DESCRIPTION The Turkey Point site is located on the shore of Biscayne Bay, approximately 25 miles south of Miami, Florida, 8 miles east of Florida City and 9 miles southeast of Homestead, Florida. Units 3 and 4 are essentially identical pressurized water reactors (see Figure 1.1, Site Photo, below). The two nuclear units are located adjacent to two oil and gas fired units (which are not considered in this study). The nuclear units were designed and constructed by Bechtel Energy Corporation.

The reactor coolant system consists of three similar heat transfer loops connected in parallel to the reactor pressure vessel. Each loop contains a reactor coolant pump, steam generator, and associated piping and valves. In addition, the system includes a pressurizer, a pressurizer relief tank, interconnecting piping, and the instrumentation necessary for operational control. All system equipment, except for the digital pressure indicator, three wide range pressure transmitters, and the containment isolation and process actuated valves located in the lines connected to the pressurizer relief tank, are located in the containment building.
The containment is a steel lined, post-tensioned, reinforced-concrete structure consisting of a vertical cylinder with a hemispherical dome, supported on a flat TLG Services, Inc.

Heat produced in the reactor is converted to electrical energy by the steam and power conversion system. The function of the turbine generator is to receive steam from the steam generators, economically convert a portion of the thermal energy contained in the steam to electrical energy, and provide extract steam for six stages of feedwater heating. The turbine generator serves no safety function and has two reheaters before entering the low pressure turbines. The exhaust steam from the two low pressure turbines is condensed in the condenser. With the completion of the extended power uprate activities (described below), Units 3 and 4 will each have a net electrical output of 804 megawatt-electric (MWe).
Heat rejected in the main condensers is removed by the circulating water system. The system provides cooling water for removal of heat loads developed in the plant's main condenser which condenses the steam exhaust from the turbine. Cooling water for the condenser is supplied by a network of cooling canals.
Modifications are underway to increase the power output for each unit. The Extended Power Uprate (EPU) will be a 15-percent uprate. The original licensed core rated thermal power level was 2,200 megawatts-thermal (MWt),
and after a 4.5-percent stretch power uprate in 1996, the current licensed thermal power rating is 2,300 MWt. The uprate licensed thermal power would then be 2,644 MWt. The modifications necessary to support the power uprate will be implemented during the 2010, 2011 and 2012 refueling outages. The impact of the EPU (e.g., from increased neutron fluence), although not significant in decommissioning, is considered in this analysis.
.1.3  REGULATORY GUIDANCE The Nuclear Regulatory Commission (NRC) provided initial decommissioning requirements in its rule "General Requirements for Decommissioning Nuclear Facilities," issued in June 1988.[2] This rule set forth financial criteria for decommissioning licensed nuclear power facilities. The regulation addressed decommissioning planning needs, timing, funding methods, and environmental review requirements. The intent of the rule was to ensure that decommissioning would be accomplished in a safe and timely manner and that adequate funds would be available for this purpose. Subsequent to the rule, the NRC issued Regulatory Guide 1.159, "Assuring the Availability of Funds for Decommissioning Nuclear Reactors,"[31 which provided additional guidance to the licensees of nuclear facilities on the financial methods acceptable to the TLG Services,Inc.

Turkey PointNuclear Plant, Units 3 and 4                   Document F02-1630-002, Rev. 0 DecommissioningCost Analysis                                      Section 1, Page 4 of 10 NRC staff for complying with the requirements of the rule. The regulatory guide addressed the funding requirements and provided guidance on the content and form of the financial assurance mechanisms indicated in the rule.
The rule defined three decommissioning alternatives as being acceptable to the NRC: DECON, SAFSTOR, and ENTOMB. The DECON alternative assumes that any contaminated or activated portion of the plant's systems, structures and facilities are removed or decontaminated to levels that permit the site to be released for unrestricted use shortly after the cessation of plant operations.
The rule also placed limits on the time allowed to complete the decommissioning process. For SAFSTOR, the process is restricted in overall duration to 60 years, unless it can be shown that a longer duration is necessary to protect public health and safety. The guidelines for ENTOMB are similar, providing the NRC with both sufficient leverage and flexibility to ensure that these deferred options are only used in situations where it is reasonable and consistent with the definition of decommissioning. At the conclusion of a 60-year dormancy period (or longer for ENTOMB if the NRC approves such a case), the site would still require significant remediation to meet the unrestricted release limits for license termination.
The ENTOMB alternative has not been viewed as a viable option for power reactors due to the significant time required to isolate the long-lived radionuclides for decay to permissible levels. However, with rulemaking permitting the controlled release of a site,[4] the NRC has re-evaluated this alternative. The resulting feasibility study, based upon an assessment by Pacific Northwest National Laboratory, concluded that the method did have conditional merit for some, if not most reactors. However, the staff also found that additional rulemaking would be needed before this option could be treated as a generic alternative. The NRC had considered rulemaking to alter the 60-year time for completing decommissioning and to clarify the use of engineered barriers for reactor entombments.[5]
The NRC's staff has recommended that rulemaking be deferred, based upon several factors, e.g., no licensee has committed to pursuing the option, disposition of certain waste forms, effectiveness of engineering barriers, and the NRC's current priorities, at least until after the additional research studies are complete. The NRC concurred with the staffs recommendation.
In 1996, the NRC published revisions to the general requirements for decommissioning nuclear power plants.[61 When the decommissioning regulations were adopted in 1988, it was assumed that the majority of licensees would operate for their full licensed life. However, shortly after the regulations were enacted, several licensees permanently and prematurely TLG Services, Inc.

Exemptions from certain operating requirements were required once the reactor was defueled to facilitate the decommissioning. Each case was handled individually, without clearly defined generic requirements.
The NRC amended the decommissioning regulations in 1996 to clarify ambiguities and codify procedures and terminology as a means of enhancing efficiency and uniformity in the decommissioning process. The amendments allow for greater public participation and better define the transition process from operations to decommissioning.
Under the revised regulations, licensees will submit written certification to the NRC within 30 days after the decision to cease operations. Certification will also be required once the fuel is permanently removed from the reactor vessel.
Submittal of these notices will entitle the licensee to a fee reduction and eliminate the obligation to follow certain requirements needed only during operation of the reactor. Within two years of submitting notice of permanent cessation of operations, the licensee is required to submit a Post-Shutdown Decommissioning Activities Report (PSDAR) to the NRC. The PSDAR describes the planned decommissioning activities, the associated sequence and schedule, and an estimate of expected costs. Prior to completing decommissioning, the licensee is required to submit an application to the NRC to terminate the license, which will include a license termination plan (LTP).
1.3.1 Nuclear Waste Policy Act Congress passed the "Nuclear Waste Policy Act"[7] (NWPA) in 1982, assigning the federal government's long-standing responsibility for disposal of the spent nuclear fuel and high level radioactive waste created by the commercial nuclear generating plants to the DOE. The NWIPA provided that DOE would enter into contracts with utilities in which DOE would promise to take the utilities' spent fuel and high-level radioactive waste and utilities would pay the cost of the disposition services for that material. The NWPA, along with the individual contracts with the utilities, specified that the DOE was to begin accepting spent fuel by January 31, 1998.
Since the original legislation, the DOE has announced several delays in the program schedule. By January 1998, the DOE had failed to accept any spent fuel or high level waste, as required by the NWPA and utility contracts. Delays continue and, as a result, generators have initiated legal action against the DOE in an attempt to obtain compensation for DOE's breach of contract.

FPL filed a lawsuit in 2004 claiming damages for DOE's failure to perform as originally prescribed in the standard disposal contract.
On March 31, 2009, FPL executed a Settlement Agreement with the DOE and the Department of Justice (DoJ). In the Agreement, FPL settled the lawsuit in exchange for payments. The payments are intended to cover those costs incurred for managing and storing the spent fuel that it would not have incurred but for DOE's delay in performance.
While the DOE is responsible for the costs incurred until it fulfills its obligation, certain assumptions are needed to assess the financial impact on the identified decommissioning cost scenarios. The assumptions and methodology employed to quantify the expected level of compensation are outlined in Section 3.8.
It is generally necessary that spent fuel be cooled and stored for a minimum period at the generating site prior to transfer. As such, the NRC requires that licensees establish a program to manage and provide funding for the management of all irradiated fuel at the reactor site until title of the fuel is transferred to the Secretary of Energy, pursuant to 10 CFR Part 50.54(bb).[8] This funding requirement is fulfilled through inclusion of certain cost elements in the decommissioning estimates, for example, expansion and operation of the Independent Spent Fuel Storage Installation (ISFSI) subsequent to plant operations and continued operation of the spent fuel pools.
The spent fuel pools are expected to contain freshly discharged assemblies (from the most recent refueling cycles) as well as the final reactor core at shutdown. Over the following five and one half years the assemblies are packaged into DOE-provided multi-purpose canisters (MPCs) for transfer to the DOE or in dry-shielded canisters (DSCs) for interim storage at the ISFSI. It is assumed that this period provides the necessary cooling for the final core to meet the transport and/or storage requirements for decay heat.
DOE's contracts with utilities order the acceptance of spent fuel from utilities based upon the oldest fuel receiving the highest priority. [While DOE's acceptance priority ranking is based on the date that spent nuclear fuel was permanently discharged, with the oldest spent nuclear TLG Services, Inc.

Turkey PointNuclear Plant, Units 3 and 4                  Document F02-1630-002, Rev. 0 DecommissioningCost Analysis                                      Section 1, Page 7 of 10 fuel, on an industry-wide basis, given the higher priority, the generator has the right to determine which spent nuclear fuel is delivered, provided that it is in compliance with the Standard Contract. DOE contracts also provide mechanisms for altering the oldest fuel first allocation scheme, including emergency deliveries, exchanges of allocations amongst utilities and the option of providing priority acceptance from permanently shutdown nuclear reactors.] Because it is unclear how these mechanisms may operate once DOE begins accepting spent fuel from commercial reactors, this study conservatively assumes that DOE will accept spent fuel in an oldest fuel first order. For purposes of this analysis, the first assemblies removed from the Turkey Point site are conservatively assumed to be in 2031. With an estimated, maximum rate of transfer of 3,000 metric tons of uranium (MTU)/year, completion of the removal of fuel from the site is conservatively projected to be in the year 2072. Consequently, costs are included within the estimates for the long-term caretaking of the spent fuel at the Turkey Point site until the year 2072.
FPL's position is that the DOE has a contractual obligation to accept Turkey Point's fuel far earlier than the projections set out above consistent with its contract commitments. No assumption made in this study should be interpreted to be inconsistent with this claim. However, at this time, including the cost of storing spent fuel in this study is the most reasonable. approach because it insures the availability of sufficient decommissioning funds at the end of the station's life if, contrary to its contractual obligation, the DOE has not performed earlier.
An ISFSI, which is operated under a general (10 CFR Part 50) license, has been constructed to support management of the spent fuel at the site until the DOE is able to complete the transfer to a federal repository. It is assumed that the ISFSI will be expanded subsequent to plant shutdown to support decommissioning operations. As such, the fuel that cannot be transferred directly to the DOE from the wet pools is packaged for interim storage at the ISFSI. This will allow decommissioning to continue on the nuclear units.
1.3.2 Low-Level Radioactive Waste Acts The contaminated         and activated material generated in the decontamination and dismantling of a commercial nuclear reactor is classified as low-level (radioactive) waste, although not all of the material is suitable for "shallow-land" disposal. With the passage of the "Low-Level Radioactive Waste Policy Act" in 1980,[91 and its TLG Services,Inc.

Turkey PointNuclear Plant,Units 3 and 4                    Document F02-1630-002, Rev. 0 DecommissioningCost Analysis                                       Section 1, Page 8 of 10 Amendments of 1985,[1&deg;1 the states became ultimately responsible for the disposition of low-level radioactive waste generated within their own borders. However, with the exception of Texas (which has issued a license for a new facility), no new compact facilities have been successfully sited, licensed, and constructed.
In past studies, there were two facilities available to FPL for the disposal of low-level radioactive waste generated by Turkey Point. As of July 1, 2008, however, the facility in Barnwell, South Carolina was closed to generators outside the Atlantic Compact (comprised of the states of Connecticut, New Jersey and South Carolina). This leaves the facility in Clive, Utah, operated by EnergySolutions, as the only currently available destination for low-level radioactive waste requiring controlled disposal, until the construction of Waste Control Specialist's facility in Andrews County, Texas, is complete.
For the purpose of this analysis, the EnergySolutions' facility is used as the basis for estimating the disposal cost for the majority of the radioactive waste (Class A [11]). EnergySolutions does not have a license to dispose of the more highly radioactive waste (Classes B and C), for example, generated in the dismantling of the reactor vessel. As a proxy, the disposal cost for this material is based upon the last published rate schedule for non-compact waste for the Barnwell facility, adjusted for escalation of the Atlantic Compact rates.
The dismantling of the components residing closest to the reactor core generates radioactive waste that may be considered unsuitable for shallow-land disposal (i.e., low-level radioactive waste with concentrations of radionuclides that exceed the limits established by the NRC for Class C radioactive waste (GTCC)). The Low-Level Radioactive Waste Policy Amendments Act of 1985 assigned the federal government the responsibility for the disposal of this GTCC material. The Act also stated that the beneficiaries of the activities resulting in the generation of such radioactive waste bear all reasonable costs of disposing of such waste. However, to date, the federal government has not identified a cost for disposing of GTCC or a schedule for acceptance. For purposes of this estimate, the GTCC radioactive waste has been assumed to be packaged and disposed of as high-level waste, at a cost equivalent to that envisioned for the spent fuel.
For purposes of this analysis, GTCC is packaged in the same canisters that are designated for the disposal of spent fuel (modified for the different waste form). The GTCC material is stored with the spent fuel TLG Services, Inc.

GTCC is shipped as it is generated in the SAFSTOR scenario since it occurs after the fuel has been removed from the site.
A significant portion of the waste material generated during decommissioning may only be potentially contaminated by radioactive materials. This waste can be analyzed on site or shipped off site to licensed facilities for further analysis, for processing and/or for conditioning/recovery. Reduction in the volume of low-level radioactive waste requiring disposal in a licensed low-level radioactive waste disposal facility can be accomplished through a variety of methods, including analyses and surveys or decontamination to eliminate the portion of waste that does not require disposal as radioactive waste, compaction, incineration or metal melt. The estimates for Turkey Point reflect the savings from waste recovery/volume reduction.
1.3.3 Radiological Criteria for License Termination In 1997, the NRC published Subpart E, "Radiological Criteria for License Termination,"[ 12I amending 10 CFR Part 20. This subpart provides radiological criteria for releasing a facility for unrestricted use.
The regulation states that the site can be released for unrestricted use if radioactivity levels are such that the average member of a critical group would not receive a Total Effective Dose Equivalent (TEDE) in excess of 25 millirem per year, and provided that residual radioactivity has been reduced to levels that are As Low As Reasonably Achievable (ALARA).
The decommissioning estimates assume that the Turkey Point site will be remediated to a residual level consistent with the NRC-prescribed level. It should be noted that the NRC and the Environmental Protection Agency (EPA) differ on the amount of residual radioactivity considered acceptable in site remediation. The EPA has two limits that apply to radioactive materials. An EPA limit of 15 millirem per year is derived from criteria established by the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA or Superfund).[ 13]
An additional and separate limit of 4 millirem per year, as defined in 40 14 CFR &sect; 141.16, is applied to drinking water.[ ]
On October 9, 2002, the NRC signed an agreement with the EPA on the radiological decommissioning and decontamination of NRC-licensed sites. The Memorandum of Understanding (MOU)[15] provides that EPA will defer exercise of authority under CERCLA for the majority of facilities decommissioned under NRC authority. The MOU also includes TLG Services, Inc.

The MOU does not impose any new requirements on NRC licensees and should reduce the involvement of the EPA with NRC licensees who are decommissioning. Most sites are expected to meet the NRC criteria for unrestricted use, and the NRC believes that only a few sites will have groundwater or soil contamination in excess of the levels specified in the MOU that trigger consultation with the EPA. However, if there are other hazardous materials on the site, the EPA may be involved in the cleanup. As such, the possibility of dual regulation remains for certain licensees. The present study does not include any costs for this occurrence.

: 2. DECOMMISSIONING ALTERNATIVES Detailed cost estimates were developed to decommission Turkey Point based upon the approved decommissioning alternatives: DECON and SAFSTOR. Although the alternatives differ with respect to technique, process, cost, and schedule, they attain the same result: the ultimate release of the site for unrestricted use.
Two decommissioning scenarios were evaluated for the Turkey Point nuclear units.
In both instances a 60-year operating life was assumed. The scenarios selected are representative of alternatives available to the owner and are defined as follows:
: 1. DECON: The operating licenses for Units 3 and 4 currently expire in July 2032 and April 2033, respectively. The first scenario assumes that decommissioning activities at the two units are sequenced and integrated so as to minimize the total duration of the physical dismantling processes. Any residual spent fuel is transferred to the ISFSI so as to facilitate decontamination and dismantling activities within the fuel handling buildings. Spent fuel storage operations continue at the site until the transfer of the fuel to the DOE is complete, assumed to be in the year 2072.
: 2. SAFSTOR: The units are placed into safe-storage shortly after the permanent cessation of operations and defueling. Spent fuel remaining in the spent fuel storage pools after a minimum cooling period is transferred to the ISFSI for interim storage, consistent with the DECON spent fuel management plan.
Decommissioning is deferred beyond the fuel storage period to the maximum extent possible; termination of the licenses would conclude within the required 60-year period. As with the DECON scenario, decommissioning activities at the two units are sequenced and integrated so as to minimize the total duration of the physical dismantling processes.
The following sections describe the basic activities associated with each alternative.
Although detailed procedures for each activity identified are not provided, and the actual sequence of work may vary, the activity descriptions provide a basis not only for estimating but also for the expected scope of work, i.e., engineering and planning at the time of decommissioning.
The conceptual approach that the NRC has described in its regulations divides decommissioning into three phases. The initial phase commences with the effective date of permanent cessation of operations and involves the transition of both plant and licensee from reactor operations (i.e., power production) to facility de-activation and closure. During the first phase, notification is to be provided to the NRC TLG Services,Inc.

The licensee is then prohibited from reactor operation.
The second phase encompasses activities during the storage period or during major decommissioning activities, or a combination of the two. The third phase pertains to the activities involved in license termination. The decommissioning estimates developed for Turkey Point are also divided into phases or periods; however, demarcation of the phases is based upon major milestones within the project or significant changes in the projected expenditures.
2.1   DECON The DECON alternative, as defined by the NRC, is "the alternative in which the equipment, structures, and portions of a facility and site containing radioactive contaminants are removed or decontaminated to a level that permits the property to be released for unrestricted use shortly after cessation of operations." This study does not address the cost to dispose of the spent fuel residing at the site; such costs are funded through a surcharge on electrical generation. However, the study does estimate the costs incurred with the interim on-site storage of the fuel pending shipment by the DOE to an off-site disposal facility.
2.1.1 Period 1 - Preparations In anticipation of the cessation of plant operations, detailed preparations are undertaken to provide a smooth transition from plant operations to site decommissioning. Through implementation of a staffing transition plan, the organization required to manage the intended decommissioning activities is assembled from available plant staff and outside resources. Preparations include the planning for permanent defueling of the reactor, revision of technical specifications applicable to the operating conditions and requirements, a characterization of the facility and major components, and the development of the PSDAR.
Engineering and Planning The PSDAIR, required within two years of the notice to cease operations, provides a description of the licensee's planned decommissioning activities, a timetable, and the associated financial requirements of the intended decommissioning program. Upon receipt of the PSDAR, the NRC will make the document available to the public for comment in a local hearing to be held in the vicinity of the reactor site. Ninety days TLG Services, Inc.

Major activities are defined as any activity that results in permanent removal of major radioactive components, permanently modifies the structure of the containment, or results in dismantling components (for shipment) containing GTCC, as defined by 10 CFR &sect;61. Major components are further defined as comprising the reactor vessel and internals, large bore reactor coolant system piping, steam generators, and other large components that are radioactive. The NRC includes the following additional criteria for use of the &sect;50.59 process in decommissioning. The proposed activity must not:
              " foreclose release of the site for possible unrestricted use, o  significantly increase decommissioning costs, o  cause any significant environmental impact, or o  violate the terms of the licensee's existing license.
Existing operational technical specifications are reviewed and modified to reflect plant conditions and the safety concerns associated with permanent cessation of operations. The environmental impact associated with the planned decommissioning activities is also considered.
Typically, a licensee will not be allowed to proceed if the consequences of a particular decommissioning activity are greater than that bounded by previously evaluated environmental assessments or impact statements.
In this instance, the licensee would have to submit a license amendment for the specific activity and update the environmental report.
The decommissioning program outlined in the PSDAR will be designed to accomplish the required tasks within the ALARA guidelines (as defined in 10 CFR &sect;20) for protection of personnel from exposure to radiation hazards. It will also address the continued protection of the health and safety of the public and the environment during the dismantling activity. Consequently, with the development of the PSDAR, activity specifications, cost-benefit and safety analyses, and work packages and procedures, would be assembled to support the proposed decontamination and dismantling activities.

0    Characterization of the site and surrounding environs. This includes radiation surveys of work areas, major components (including the reactor vessel and its internals), internal piping, and primary shield cores.
o    Isolation of the spent fuel storage pools and fuel handling systems, such that decommissioning operations can commence on the balance of the plant. The pools will remain operational for approximately five and one half years following the cessation of operations before the inventory resident in the core at shutdown can be transferred to the DOE or to the ISFSI for interim storage.
o    Specification of transport and disposal requirements for activated materials and/or hazardous materials, including shielding and waste stabilization.
0 Development of procedures for occupational exposure control, control and release of liquid and gaseous effluent, processing of radwaste (including dry-active waste, resins, filter media, metallic and non-metallic components generated in decommissioning), site security and emergency programs, and industrial safety.
2.1.2 Period 2 - Decommissioning Operations This period includes the physical decommissioning activities associated with the removal' and disposal of contaminated and activated components and structures, including the amendment of the 10 CFR &sect;50 operating license(s) to release the remediated property for unrestricted use. Significant decommissioning activities in this phase include:
           "    Construction of temporary facilities and/or modification of existing facilities to support dismantling activities. This may include a centralized processing area to facilitate equipment removal and component preparations for off-site disposal.
o    Reconfiguration and modification of site structures and facilities as needed to support decommissioning operations. This may include the upgrading of roads (on- and off-site) to facilitate hauling and transport. Modifications may be required to the containment structure to facilitate access of large/heavy equipment. Modifications TLG Services, Inc.

These components can serve as their own burial containers provided that all penetrations are properly sealed and the internal contaminants are stabilized, e.g.,
with grout. Steel shielding will be added, as necessary, to those external areas of the package to meet transportation limits and regulations.
At least two years prior to the anticipated date of the completion of the remediation process, an LTP is required. Submitted as a supplement to the Final Safety Analysis Report (FSAR) or its equivalent, the plan must include: a site characterization, description of the remaining dismantling activities, plans for site remediation, procedures for the final radiation survey, designation of the end use of the site, an updated cost estimate to complete the decommissioning, and any associated environmental concerns. The NRC will notice the receipt of the plan, make the plan available for public comment, and schedule a local hearing. LTP approval will be subject to any conditions and limitations as deemed appropriate by the NRC. The licensee may then commence with the final remediation of site facilities and services, including:
           "    Removal of remaining plant systems and associated components as they become nonessential to the decommissioning program or worker health and safety (e.g., waste collection and treatment systems, electrical power and ventilation systems).
o    Removal of the steel liners from refueling canal, disposing of the activated and contaminated sections as radioactive waste. Removal of any activated/ contaminated concrete.
o    Surveys of the decontaminated areas of the containment structure.
o    Remediation and removal of the contaminated equipment and material from the auxiliary and fuel buildings and any other contaminated facility. Radiation and contamination controls will be utilized until residual levels indicate that the structures and equipment can be released for unrestricted access and conventional demolition. This activity may necessitate the dismantling and disposition of most of the systems and components (both clean and contaminated) located within these buildings. This activity facilitates surface decontamination and subsequent verification surveys required prior to obtaining release for demolition.

Material certified to be free of contamination is released for unrestricted disposition, e.g., as scrap, recycle, or general disposal. Contaminated material is characterized and segregated for additional off-site processing (disassembly, chemical cleaning, volume reduction, and waste treatment), and/or packaged for controlled disposal at a low-level radioactive waste disposal facility.
Incorporated into the LTP is the Final Survey Plan. This plan identifies the radiological surveys to be performed once the decontamination activities are completed and is developed using the guidance provided in the "Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM)." [16] This document incorporates the statistical approaches to survey design and data interpretation used by the EPA. It also identifies commercially available instrumentation and procedures for conducting radiological surveys. Use of this guidance ensures that the surveys are conducted in a manner that provides a high degree of confidence that applicable NRC criteria are satisfied. Once the survey is complete, the results are provided to the NRC in a format that can be verified. The NRC then reviews and evaluates the information, performs an independent confirmation of radiological site conditions, and makes a determination on the requested change to the operating license (that would release the property, exclusive of the ISFSI, for unrestricted use).
The NRC will amend the operating license(s) if it determines that site remediation has been performed in accordance with the LTP, and that the terminal radiation survey and associated documentation demonstrate that the facility is suitable for release.
2.1.3 Period 3 - Site Restoration Following completion of decommissioning operations, site restoration activities will begin. Efficient removal of the contaminated materials and verification that residual radionuclide concentrations are below the NRC limits will result in substantial damage to many of the structures.
Although performed in a controlled, safe manner, blasting, coring, drilling, scarification (surface removal), and the other decontamination activities will substantially degrade power block structures including the reactor, reactor, reactor auxiliary and fuel handling buildings. Under certain circumstances,        verifying   that   subsurface    radionuclide concentrations meet NRC site release requirements will require removal of grade slabs and lower floors, potentially weakening footings and TLG Services, Inc.

Turkey Point NuclearPlant, Units 3 and 4                   Document F02-1630-002, Rev. 0 Decommissioning Cost Analysis                                     Section 2, Page 8 of 13 structural supports. This removal activity will be necessary for those facilities and plant areas where historical records, when available, indicate the potential for radionuclides having been present in the soil, where system failures have been recorded, or where it is required to confirm that subsurface process and drain lines were not breached over the operating life of the station.
Prompt dismantling of site structures is clearly the most appropriate and cost-effective option. It is unreasonable to anticipate that these structures would be repaired and preserved after the radiological contamination is removed. The cost to dismantle site structures with a work force already mobilized on site is more efficient than if the process were deferred. Site facilities quickly degrade without maintenance, adding additional expense and creating potential hazards to the public as well as to future workers. Abandonment creates a breeding ground for vermin infestation as well as other biological hazards.
This cost study presumes that non-essential structures and site facilities are dismantled as a continuation of the decommissioning activity.
Foundations and exterior walls are removed to a nominal depth of three feet below grade. The three-foot depth allows for the placement of gravel for drainage, as well as topsoil, so that vegetation can be established for erosion control. Site areas affected by the dismantling activities are restored and the plant area graded as required to prevent ponding and inhibit the refloating of subsurface materials.
Non-contaminated concrete rubble produced by demolition activities is processed to remove reinforcing steel and miscellaneous embedments.
The processed material is then used on site to backfill foundation voids.
Excess non-contaminated materials are trucked to an off-site area for disposal as construction debris.
2.1.4 ISFSI Operations and Decommissioning The ISFSI will continue to operate under a general license (10 CFR &sect;50) following the amendment of the operating license(s) to release the adjacent property. Assuming the DOE starts accepting fuel from the Turkey Point spent fuel storage pools in 2031, transfer of spent fuel from the ISFSI is anticipated to begin in 2039, and continue through the year 2072.
At the conclusion of the spent fuel transfer process, the ISFSI will be decommissioned. The NRC will terminate the &sect;50 license when it TLG Services, Inc.

Turkey Point NuclearPlant, Units 3 and 4                    Document F02-1630-002, Rev. 0 DecommissioningCost Analysis                                        Section 2, Page 9 of 13 determines that the remediation of the ISFSI has been performed in accordance with an ISFSI license termination plan and that the final radiation survey and associated documentation demonstrate that the facility is suitable for release. Once the requirements are satisfied, the NRC can terminate the license for the ISFSI.
Spent fuel is stored on the ISFSI in multi-purpose canisters, with a concrete overpack. For purposes of this cost analysis, it is assumed that once the inner canisters containing the spent fuel assemblies have been removed, any required decontamination performed on the storage overpack (some minor activation is assumed), and the license for the facility terminated, the concrete overpacks can be dismantled using conventional techniques for the demolition of reinforced concrete. The concrete storage pad is then removed and the area regraded.
2.2 SAFSTOR The NRC defines SAFSTOR as "the alternative in which the nuclear facility is placed and maintained in a condition that allows the nuclear facility to be safely stored and subsequently decontaminated (deferred decontamination) to levels that permit release for unrestricted use." The facility is left intact (during the dormancy period), with structures maintained in a sound condition. Systems that are not required to support the spent fuel pools or site surveillance and security are drained, de-energized, and secured. Minimal cleaning/removal of loose contamination and/or fixation and sealing of remaining contamination are performed. Access to contaminated areas is secured to provide controlled access for inspection and maintenance.
The engineering and planning requirements are similar to those for the DECON alternative, although they are limited in scope with no large scale dismantling activities anticipated. Site preparations are also similar to those for the DECON alternative. However, with the exception of the required radiation surveys and site characterizations, the mobilization and preparation of site facilities is less extensive.
2.2.1 Period 1 - Preparations Preparations for long-term storage include the planning for permanent defueling of the reactor, revision of technical specifications appropriate to the operating conditions and requirements, a characterization of the facility and major components, and the development of the PSDAR.

o Isolating of the spent fuel storage services and fuel handling systems so that safe-storage operations may commence on the balance of the plant. This activity may be carried out by plant personnel in accordance with existing operating technical specifications. Activities are scheduled around the fuel handling systems to the greatest extent possible.
o    Transferring of the spent fuel from the storage pools to the DOE or to the ISFSI for interim storage, following the minimum required cooling period in the spent fuel pools.
o    Draining and de-energizing of the non-contaminated systems not required to support continued site operations or maintenance.
o    Disposing of contaminated filter elements and resin beds not required for processing wastes from layup activities for future operations.
o    Draining of the reactor vessel, with the internals left in place and the vessel head secured.
Draining and de-energizing non-essential, contaminated systems with decontamination as required for future maintenance and inspection.
o    Preparing lighting and alarm systems whose continued use is required; de-energizing portions of fire protection, electric power, and HVAC systems whose continued use is not required.
o    Cleaning of the loose surface contamination from building access pathways.
Performing an interim radiation survey of the plant, posting warning signs where appropriate.

2.2.2 Period 2 - Dormancy The second phase identified by the NRC in its rule addresses licensed activities during a storage period and is applicable to the dormancy phases of the deferred decommissioning alternatives. Dormancy TLG Services, Inc.

Turkey PointNuclear Plant, Units 3 and 4                   Document F02-1630-002, Rev. 0 Decommissioning Cost Analysis                                     Section 2, Page 11 of 13 activities include a 24-hour security force, preventive and corrective maintenance on security systems, area lighting, general building maintenance, heating and ventilation of buildings, routine radiological inspections of contaminated structures, maintenance of structural integrity, and a site environmental and radiation monitoring program.
Resident maintenance personnel perform equipment maintenance, inspection activities, routine services to maintain safe conditions, adequate lighting, heating, and ventilation, and periodic preventive maintenance on essential site services.
An environmental surveillance program is carried out during the dormancy period to ensure that releases of radioactive material to the environment are prevented and/or detected and controlled. Appropriate emergency- procedures are established and initiated for potential releases that exceed prescribed limits. The environmental surveillance program constitutes an abbreviated version of the program in effect during normal plant operations.
Security during the dormancy period is conducted primarily to prevent unauthorized entry and to protect the public from the consequences of its own actions. The security fence, sensors, alarms, and other surveillance equipment provide security. Fire and radiation alarms are also monitored and maintained.
Consistent with the DECON alternative, the spent fuel storage pools are emptied within five and one half years of the cessation of operations.
The transfer of the&#xfd; spent fuel to the DOE continues throughout the dormancy period until completed in 2072. Once emptied, the ISFSI is secured for storage and decommissioned along with the power block structures in Period 4.
After a period of storage (such that license termination is accomplished within 60 years of final shutdown), it is required that the licensee submit an application to terminate the license, along with an LTP (described in Section 2.1.2), thereby initiating the third phase.
2.2.3 Periods 3 and 4 - Delayed Decommissioning Prior to the commencement of decommissioning operations, preparations are undertaken to reactivate site services and prepare for decommissioning. Preparations include engineering and planning, a detailed site characterization, and the assembly of a decommissioning management organization. Final planning for activities and the writing TLG Services, Inc.

Turkey Point NuclearPlant, Units 3 and 4                     Document F02-1630-002, Rev. 0 Decommissioning Cost Analysis                                       Section 2, Page 12 of 13 of activity specifications and detailed procedures are also initiated at this time.
Much of the work in developing a termination plan is relevant to the development of the detailed engineering plans and procedures. The activities associated with this phase and the follow-on decontamination and dismantling processes are detailed in Sections 2.1.1 and 2.1.2. The primary difference between the sequences anticipated for the DECON and this deferred scenario is the absence, in the latter, of any constraint on the availability of the fuel storage facilities for decommissioning.
The additional decay time is not expected to significantly affect the quantities of radioactive wastes generated from system and structure removal operations. Given the levels of radioactivity and spectrum of radionuclides expected from sixty years of plant operation, no plant process system identified as being contaminated upon final shutdown will become releasable due to the decay period alone, i.e., there is no significant reduction in the waste generated from the decommissioning activities. However, due to the lower activity levels, a greater percentage of the waste volume can be designated for off-site processing and recovery.
The delay in decommissioning also yields lower working area radiation levels. As such, the estimates for this delayed scenario incorporate reduced ALARA controls for the SAFSTOR's lower occupational exposure potential.
Although the initial radiation levels due to 60CO will decrease during the dormancy period, the internal components of the reactor vessel will still exhibit sufficiently high radiation dose rates to require remote sectioning under water due to the presence of long-lived radionuclides such as 94 Nb, 59Ni, and 6 3Ni. Therefore, the dismantling procedures described for the DECON alternative would still be employed during this scenario. Portions of the biological shield wall will still be radioactive due to the presence of activated trace elements with long half-lives (152Eu and 154Eu). Decontamination will require controlled removal and disposal. It is assumed that radioactive corrosion products on inner surfaces of piping and components will not have decayed to levels that will permit unrestricted use or allow conventional removal.
These systems and components will be surveyed as they are removed and disposed of in accordance with the existing radioactive release criteria.

Dismantling, as a continuation of the decommissioning process, is clearly the most appropriate and cost-effective option, as described in Section 2.1.3. The basis for the dismantling cost in this scenario is consistent with that described for DECON, presuming the removal of structures and site facilities to a nominal depth of three feet below grade and the limited restoration of the site.

: 3. COST ESTIMATE The cost estimates prepared for decommissioning Turkey Point consider the unique features of the site, including the NSSS, power generation systems, support services, site buildings, and ancillary facilities. The basis of the estimates, including the sources of information relied upon, the estimating methodology employed, site-specific considerations, and other pertinent assumptions, is described in this section.
3.1 BASIS OF ESTIMATE The estimates were developed using the site-specific, technical information from the 2005 analysis. This information was reviewed for the current analysis and updated as deemed appropriate. The site-specific considerations and assumptions used in the previous evaluation were also revisited. Modifications were incorporated where new information was available or experience from ongoing decommissioning programs provided viable alternatives or improved processes.
3.2 METHODOLOGY The methodology used to develop the estimates follows the basic approach originally presented in the AIF/NESP-036 study report, "Guidelines for Producing Commercial Nuclear Power Plant Decommissioning Cost Estimates," [171 and the DOE "Deconmmissioning Handbook."[18]                  These documents present a unit factor method for estimating decommissioning activity costs, which simplifies the estimating calculations. Unit factors for concrete removal ($/cubic yard), steel removal ($/ton), and cutting costs ($/inch) are developed using local labor rates. The activity-dependent costs are estimated with the item quantities (cubic yards and tons), developed from plant drawings and inventory documents. Removal rates and material costs for the conventional disposition of components and structures rely upon information available in the industry publication, "Building Construction Cost Data," published by R.S. Means.[ 19]
The unit factor method provides a demonstrable basis for establishing reliable cost estimates. The detail provided in the unit factors, including activity duration, labor costs (by craft), and equipment and consumable costs, ensures that essential elements have not been omitted. Appendix A presents the detailed development of a typical unit factor. Appendix B provides the values contained within one set of factors developed for this analysis.

In addition, the planning and engineering for the Pathfinder, Shoreham, Rancho Seco, Trojan, Yankee Rowe, Big Rock Point, Maine Yankee, Humboldt Bay-3, Oyster Creek, Connecticut Yankee, and San Onofre-1 nuclear units have provided additional insight into the process, the regulatory aspects, and the technical challenges of decommissioning commercial nuclear units.
Work Difficulty Factors TLG has historically applied work difficulty adjustment factors (WDFs) to account for the inefficiencies in working in a power plant environment. WDFs are assigned to each unique set of unit factors, commensurate with the inefficiencies associated with working in confined, hazardous environments.
The ranges used for the WDFs are as follows:
         " Access Factor                                     10% to 20%
o   Respiratory Protection Factor                   10% to 50%
o   Radiation/ALARA Factor                          10% to 37%
Protective Clothing Factor                      10% to 30%
o    Work Break Factor                                    8.33%
The factors and their associated range of values were developed in conjunction with the AIF/NESP-036 study. The application of the factors is discussed in more detail in that publication.
Scheduling Program Durations The unit factors, adjusted by the WDFs as described above, are applied against the inventory of materials to be removed in the radiological controlled areas.
The resulting man-hours, or crew-hours, are used in the development of the decommissioning program schedule, using resource loading and event sequencing considerations. The scheduling of conventional removal and dismantling activities is based upon productivity information available from the "Building Construction Cost Data" publication.
An activity duration critical path is used to determine the total decommissioning program schedule. The schedule is relied upon in calculating the carrying costs, which include program management, administration, field TLG Services,Inc.

This systematic approach for assembling decommissioning estimates ensures a high degree of confidence in the reliability of the resulting costs.
3.3 IMPACT OF DECOMMISSIONING MULTIPLE REACTOR UNITS In estimating the near simultaneous decommissioning of two co-located reactor units there can be opportunities to achieve economies of scale, by sharing costs between units, and coordinating the sequence of work activities. There will also be schedule constraints, particularly where there are requirements for specialty equipment and staff, or practical limitations on when final status surveys can take place. For purposes of the estimates, Units 3 and 4 are assumed to be essentially identical. Common facilities have been assigned to Unit 4. A summary of the principal impacts are listed below.
     "  The sequence of work generally follows the principal that the work is done at Unit 3 first, followed by similar work at Unit 4. This permits the experience gained at Unit 3 to be applied by the workforce at the second unit. It should be noted however, that the estimates do not consider productivity improvements at the second unit, since there is little documented experience with decommissioning two units simultaneously.
The work associated with developing activity specifications and procedures can, however, be considered essentially identical between the two units, therefore the second unit costs are assumed to be a fraction of the first unit (e.g., - 43% in DECON).
     "  Segmenting the reactor vessel and internals will require the use of special equipment. The decommissioning project will be scheduled such that Unit 4's reactor internals and vessel are segmented after the activities at Unit 3 have been completed, permitting the sharing of the cutting equipment.
     "  Some program management and support costs, particularly costs associated with- the more senior positions, can be avoided with two reactors undergoing decommissioning simultaneously. As a result, the estimates are based on a "lead" unit that includes these senior positions, and a "second" unit that excludes these positions. The designation as lead is based on the unit undertaking the most complex tasks (for instance vessel segmentation) or performing tasks for the first time.
     "  The final radiological survey schedule     is also affected by a two-unit decommissioning schedule. It would be      considered impractical to try to complete the final status survey of Unit   3, while Unit 4 still has ongoing radiological remediation work and waste    handling in process. As such, the transfer of the spent fuel from the         storage pools and subsequent TLG Services, Inc.

     "   The final demolition of buildings at Units 3 and 4 are considered to take place concurrently.
o   The first unit to enter decommissioning incurs the majority of site characterization costs.
o   Shared systems and structures are generally assigned to Unit 4.
o   Station costs such as emergency response fees, regulatory agency fees, corporate overhead, and insurance are generally allocated on an equal basis between the two units.
     "   Dormancy costs (to maintain the units in safe-storage) in the SAFSTOR scenario are allocated on an equal basis between the two units.
3.4  FINANCIAL COMPONENTS OF THE COST MODEL TLG's proprietary decommissioning cost model, DECCER, produces a number of distinct cost elements. These direct expenditures, however, do not comprise the total cost to accomplish the project goal, i.e., license termination and site restoration.
Inherent in any cost estimate that does not rely on historical data is the inability to specify the precise source of costs imposed by factors such as tool breakage, accidents, illnesses, weather delays, and labor stoppages. In the DECCER cost model, contingency fulfills this role. Contingency is added to each line item to account for costs that are difficult or impossible to develop analytically. Such costs are historically inevitable over the duration of a job of this magnitude; therefore, this cost analysis includes funds to cover these types of expenses.
3.4.1  Contingency The activity- and period-dependent costs are combined to develop the total decommissioning cost. A contingency is then applied on a line-item basis, using one or more of the contingency types listed in the AIF/NESP-036 study. "Contingencies" are defined in the American Association of Cost Engineers "Project and Cost Engineers' Handbook"[20 ] as "specific provision for unforeseeable elements of cost within the defined project scope; particularly important where previous experience relating estimates and actual costs has shown that unforeseeable events which will increase costs are likely to occur." The cost elements in this analysis are based upon ideal conditions and TLG Services, Inc.

In the AIF/NESP-036 study, the types of unforeseeable events that are likely to occur in decommissioning are discussed and guidelines are provided for percentage contingency in each category. It should be noted that contingency, as used in this analysis, does not account for price escalation and inflation in the cost of decommissioning over the remaining operating life of the station.
Contingency funds are an integral part of the total cost to complete the decommissioning process. Exclusion of this component puts at risk a successful completion of the intended tasks and, potentially, subsequent related activities. For this study, TLG examined the major activity-related problems (decontamination, segmentation, equipment handling, packaging, transport, and waste disposal) that necessitate a contingency. Individual activity contingencies ranged from 10% to 75%,
depending on the degree of difficulty judged to be appropriate from TLG's actual decommissioning experience. The contingency values used in this study are as follows:

A composite value is then reported at the end of each detailed estimate (as provided in Appendix C and D). For example, the composite contingency value reported for the decommissioning activity for the DECON alternative in Appendix C is approximately 17.4% and for the SAFSTOR alternative in Appendix D is approximately 16.2%.
3.4.2 Financial Risk In addition to the routine uncertainties addressed by contingency, another cost element that is sometimes necessary to consider when bounding decommissioning costs relates to uncertainty, or risk.
Examples can include changes in work scope, pricing, job performance, and other variations that could conceivably, but not necessarily, occur.
Consideration is sometimes necessary to generate a level of confidence in the estimate, within a range of probabilities. TLG considers these types of costs under the broad term "financial risk." Included within the category of financial risk are:
0 Transition activities and costs: ancillary expenses associated with eliminating 50% to 80% of the site labor force shortly after the cessation of plant operations, added cost for worker separation packages throughout the decommissioning program, national or company-mandated retraining, and retention incentives for key personnel.
Delays in approval of the decommissioning plan due to intervention, public participation in local community meetings, legal challenges, and national and local hearings.
* Changes in the project work scope from the baseline estimate, involving the discovery of unexpected levels of contaminants, contamination in places not previously expected, contaminated soil previously undiscovered (either radioactive or hazardous material contamination), variations in plant inventory or configuration not indicated by the as-built drawings.
a    Regulatory changes, for example, affecting worker health and safety, site release criteria, waste transportation, and disposal.
* Policy decisions altering national commitments (e.g., in the ability to accommodate certain waste forms for disposition), or in the timetable for such, for example, the start and rate of acceptance of spent fuel by the DOE.

Items subject to widespread price competition (such as materials) may not show significant variation; however, others such as waste disposal could exhibit large pricing uncertainties, particularly in markets where limited access to services is available.
This cost study does not add any additional costs to the estimate for financial risk, since there is insufficient historical data from which to project future liabilities. Consequently, the areas of uncertainty or risk are revisited periodically and addressed through repeated revisions or updates of the base estimates.
3.5 SITE-SPECIFIC CONSIDERATIONS There are a number of site-specific considerations that affect the method for dismantling and removal of equipment from the site and the degree of restoration required. The cost impact of the considerations identified below is included in thiscost study.
3.5.1 Spent Fuel Management The cost to dispose the spent fuel generated from plant operations is not reflected within the estimates to decommission Turkey Point. Ultimate disposition of the spent fuel is within the province of the DOE's Waste Management System, as defined by the Nuclear Waste Policy Act. As such, the disposal cost is financed by a 1 mill/kWhr surcharge paid into the DOE's waste fund during operations. However, the NRC requires licensees to establish a program to manage and provide funding for the management of all irradiated fuel at the reactor site until title of the fuel is transferred to the Secretary of Energy. This funding requirement is fulfilled through inclusion of certain high-level waste cost elements within the estimates, as described below.
Completion of the decommissioning process is highly dependent upon the DOE's ability to remove spent fuel from the site. The timing for removal of spent fuel from the site is based upon the DOE's most recently published annual acceptance rates of 400 MTU/year for year 1, 3,800 MTU total for years 2 through 4 and 3,000 MTU/year for year 5 and beyond. The DOE contracts provide mechanisms for altering the oldest fuel first allocation scheme, including emergency deliveries, exchanges of allocations amongst utilities and the option of providing priority acceptance from permanently shutdown nuclear reactors.
Because it is unclear how these mechanisms may operate once DOE TLG Services, Inc.

ISFSI An ISFSI, which is operated under the plant's general license, has been constructed to support management of the spent fuel during operations.
The facility is assumed to be available to support spent fuel management once the units cease operation, until the DOE is able to removal all spent fuel from the site.
The ISFSI will continue to operate throughout decommissioning, and beyond the termination of the operating license in the DECON decommissioning alternative, until such time that the transfer of spent fuel to the DOE can be completed. Assuming, conservatively, that DOE begins to remove spent fuel from the site in 2031, the process is expected to be completed by the year 2072. The scenario is similar for the SAFSTOR alternative; however, based upon the expected completion date for fuel transfer, the ISFSI will be emptied prior to the commencement of decommissioning operations.
Post-shutdown and maintenance costs for the spent fuel pools and the ISFSI are also included and address the cost for staffing the facility, as well as security, insurance, and licensing fees. Costs are provided for the final disposition of the facilities once the transfer is complete.
Canister Design A Transnuclear NUHOMS-32PT system (with a 32 fuel assembly capacity) is assumed for future acquisitions. For fuel transferred directly from the pools to the DOE, the DOE is assumed to provide Transport, Aging and Disposal (TAD) canisters with a 32 assembly capacity. DOE has not provided details about the TAD canisters other than assembly capacity.
Canister Loading and Transfer The estimates include the cost for the labor and equipment to transfer and load each spent fuel canister into the DOE transport cask or to the ISFSI from the wet storage pools. Since the DOE has not published details about its cask system, this rough estimate is necessary. However, use of this estimate should not be used to infer that TLG has any detailed information on the cask system DOE will ultimately provide.

Pool operations are expected to continue approximately five and one half years after the cessation of operations. ISFSI operating costs are based upon a 39 year period of operations following the shutdown of Unit 4.
ISFSI Design Considerations A multi-purpose (storage and transport) dry shielded storage canister (DSC) with a horizontal storage module (HSM) is used as a basis for the cost analyses. The HSMs are assumed to have some level of neutron-induced activation as a result of the long-term storage of the fuel, i.e., to levels exceeding free-release limits. The cost of the disposition of this material, as well as the demolition of the ISFSI facility, is included in the estimates.
GTCC The dismantling of the reactor internals may generate radioactive waste considered unsuitable for shallow land disposal (i.e., low-level radioactive waste with concentrations of radionuclides that exceed the limits established by the NRC for Class C radioactive waste (GTCC)).
The Low-Level Radioactive Waste Policy Amendments Act of 1985 assigned the federal government the responsibility for the disposal of this material. The Act also stated that the beneficiaries of the activities resulting in the generation of such radioactive waste bear all reasonable costs of disposing of such waste. Although the DOE is responsible for disposing of GTCC waste, any costs for that service have not been determined. For purposes of this estimate, the GTCC radioactive waste is assumed to be packaged and disposed of as high-level waste, at a cost equivalent to that envisioned for the spent fuel.
For purposes of this study, GTCC is packaged in the same canisters used to store spent fuel. Disposal costs are based upon a cost equivalent to that envisioned for the spent fuel. It is not anticipated that the DOE would accept this waste prior to completing the transfer of spent fuel.
Therefore, until such time the DOE is ready to accept GTCC waste, it is reasonable to assume that this material would remain in storage at the Turkey Point site (for the DECON alternative). In the SAFSTOR alternative, the GTCC material is shipped directly to a DOE facility as it TLG Services,Inc.

3.5.2 Reactor Vessel and Internal Components The reactor pressure vessel and internal components are segmented for disposal in shielded, reusable transportation casks. Segmentation is performed in the refueling canal, where a turntable and remote cutter are installed. The vessel is segmented in place, using a mast-mounted cutter supported off the lower head and directed from a shielded work platform installed overhead in the reactor cavity. Transportation cask specifications and transportation regulations dictate the segmentation and packaging methodology.
Intact disposal of reactor vessel shells has been successfully demonstrated at several of the sites that have been decommissioned.
Access to navigable waterways has allowed these large packages to be transported, in most instances, to the Barnwell disposal site in South Carolina with minimal overland travel.
Intact disposal of the reactor vessel and internal components can provide additional savings in cost and worker exposure by eliminating the complex segmentation requirements, isolation of the GTCC material, and transport/storage of the resulting waste packages. Portland General Electric (PGE) was able to dispose of the Trojan reactor as an intact package (including the internals). However, its location on the Columbia River simplified the transportation analysis since:
0  the reactor package could be secured to the transport vehicle for the entire journey, i.e., the package was not lifted during transport, a  there were no man-made or natural terrain features between the plant site and the disposal location that could produce a large drop, and a transport speeds were very low, limited by the overland transport vehicle and the river barge.
As a member of the Northwest Compact, PGE had a site available for disposal of the package - the US Ecology facility in Washington State.
The characteristics of this arid site proved favorable in demonstrating compliance with land disposal regulations.

Turkey PointNuclear Plant, Units 3 and 4                  Document F02-1630-002, Rev. 0 DecommissioningCost Analysis                                     Section 3, Page 11 of 60 It is not known whether intact disposal (of the vessel shell or the complete vessel and internals) will be available when the St. Lucie plant ceases operation. Future viability of this option will depend upon the ultimate location of the disposal site, as well as the disposal site licensee's ability to accept highly radioactive packages and effectively isolate them from the environment. Consequently, this study assumes that the reactor vessel will require segmentation, as a bounding condition.
3.5.3 Primary System Components In the DECON alternative, the reactor coolant system components are assumed to be decontaminated using chemical agents prior to the start of dismantling operations. This type of decontamination can be expected to have a significant ALARA impact, since in this scenario the removal work is done within the first few years of shutdown. A decontamination factor (average reduction) of 10 is assumed for the process. Disposal of the decontamination solution effluent is included within the estimate as a "process chemical waste" charge. In the SAFSTOR alternative, radionuclide decay is expected to provide the same benefit and, therefore, a chemical decontamination is not included.
The following discussion deals with the removal and disposition of the steam generators, but the techniques involved are also applicable to other large components, such as heat exchangers, component coolers, and the pressurizer. The steam generators' size and weight, as well as their location within the reactor building, will ultimately determine the removal strategy.
A trolley crane is set up for the removal of the generators. It can also be used to move portions of the steam generator cubicle walls and floor slabs from the reactor building to a location where they can be decontaminated and transported to the material handling area.
Interferences within the work area, such as grating, piping, and other components are removed to create sufficient laydown space for processing these large components.
The generators are rigged for removal, disconnected from the surrounding piping and supports, and maneuvered into the open area where they are lowered onto a dolly. Each generator is rotated into the horizontal position for extraction from the containment and placed onto a multi-wheeled vehicle for transport to an on-site processing and storage area.

For cost estimating purposes, the more highly contaminated lower assembly containing the tube sheet and tube bundle are packaged for direct disposal, although additional processing may be an option. The interior volume is filled with low-density cellular concrete for stabilization of the internal contamination. Each component is then loaded onto a barge for transport to a railhead. The steam generators are then transferred to a dedicated train for transport to the disposal facility.
The lower assemblies of six retired steam generators currently stored at the site will be removed from their storage facility and disposed of along with the installed generators.
Reactor coolant piping is cut from the reactor vessel once the water level in the vessel (used for personnel shielding during dismantling and cutting operations in and around the vessel) is dropped below the nozzle zone. The piping is boxed and transported by shielded van. The reactor coolant pumps and motors are lifted out intact, packaged, and transported for processing and/or disposal.
3.5.4 Main Turbine and Condenser The main turbine is dismantled using conventional maintenance procedures. The turbine rotors and shafts are removed to a laydown area. The lower turbine casings are removed from their anchors by controlled demolition. The main condensers are also disassembled and moved to a laydown area. Material is then prepared for transportation to an off-site recycling facility where it is surveyed and designated for either decontamination or volume reduction, conventional disposal, or controlled disposal. Components are packaged and readied for transport in accordance with the intended disposition.
3.5.5 Transportation Methods Contaminated piping, components, and structural material other than the highly-activated reactor vessel and internal components will qualify as LSA-I, II or III or Surface Contaminated Object, SCO-I or II, as described in Title 49 of the Code of Federal Regulations.[ 21] The contaminated material will be packaged in Industrial Packages (IP-1, IP-2, or IP-3, as defined in 49 CFR 173.411) for transport unless demonstrated to qualify as their own shipping containers. The reactor vessel and internal components are expected to be transported in TLG Services, Inc.

It is conceivable that the reactor, due to its limited specific activity, could qualify as LSA II or III.
However, the high radiation levels on the outer surface would require that additional shielding be incorporated within the packaging so as to attenuate the dose to levels acceptable for transport.
Any fuel cladding failure that occurred during the lifetime of the plant is assumed to have released fission products at sufficiently low levels that the buildup of quantities of long-lived isotopes (e.g., 137Cs, 90 Sr, or transuranics) has been prevented from reaching levels exceeding those that permit the major reactor components to be shipped under current transportation regulations and disposal requirements.
Transport of the highly-activated metal, produced in the segmentation of the reactor vessel and internal components, will be by shielded truck cask. Cask shipments may exceed 95,000 pounds, including vessel segment(s), supplementary shielding, cask tie-downs, and tractor-trailer. The maximum level of activity per shipment assumed permissible was based upon the license limits of the available shielded transport casks. The segmentation scheme for the vessel and internal segments is designed to meet these limits.
The transport of large intact components (e.g., large heat exchangers and other oversized components) will be by a combination of truck, barge, rail, and/or multi-wheeled transporter.
Transportation costs for material requiring controlled disposal are based upon the mileage to EnergySolutions' facility in Clive, Utah.
Transportation costs for off-site waste processing are based upon the mileage to Oak Ridge, Tennessee. Truck transport costs are estimated using published tariffs from Tri-State Motor Transit.[221 3.5.6 Low-Level Radioactive Waste Disposal To the greatest extent practical, metallic material generated in the decontamination and dismantling processes is processed to reduce the total cost of controlled disposal. Material meeting the regulatory and/or site release criterion, is released as scrap, requiring no further cost consideration. Conditioning (preparing the material to meet the waste acceptance criteria of the disposal site) and recovery of the waste stream is performed off site at a licensed processing center. Any material leaving the site is subject to a survey and release charge, at a minimum.

Turkey Point NuclearPlant, Units 3 and 4                   Document F02-1630-002, Rev. 0 DecommissioningCost Analysis                                      Section 3, Page 14 of 60 The mass of radioactive waste generated during the various decommissioning activities at the site is shown on a line-item basis in the detailed Appendices C and D, and summarized in Section 5. The quantified waste summaries shown in these tables are consistent with 10 CFR Part 61 classifications. Commercially available steel containers are presumed to be used for the disposal of piping, small components, and concrete. Larger components can serve as their own containers, with proper closure of all openings, access ways, and penetrations. The volumes are calculated based on the exterior package dimensions for containerized material or a specific calculation for components serving as their own waste containers.
The more highly activated reactor components will be shipped in reusable, shielded truck casks with disposable liners. In calculating disposal costs, the burial fees are applied against the liner volume, as well as the special handling requirements of the payload. Packaging efficiencies are lower for the highly-activated materials (greater than Type A quantity waste), where high concentrations of gamma-emitting radionuclides limit the capacity of the shipping canisters.
Disposal fees are based upon estimated charges, with surcharges added for the highly-activated components, for example, generated in the segmentation of the reactor vessel. The cost to dispose of the lowest level and majority of the material generated from the decontamination and dismantling activities is based upon FPL's current cost for disposal at the EnergySolutions facility in Clive, Utah. Disposal costs for the higher activity waste (Class B and C) were based upon the last published rate schedule for non-compact waste for the Barnwell facility (as a proxy),
adjusted for escalation of the Atlantic Compact rates.
3.5.7 Site Conditions Following Decommissioning The NRC will terminate the site license if it determines that site remediation has been performed in accordance with the license termination plan, and that the terminal radiation survey and associated documentation demonstrate that the facility is suitable for release. The NRC's involvement in the decommissioning process will end at this point. Building codes and environmental regulations will dictate the next step in the decommissioning process, as well as the owner's own future plans for the site.
Non-essential structures or buildings severely damaged                       in decontamination process are removed to a nominal depth of three feet TLG Services, Inc.

Concrete rubble generated from demolition activities is processed and made available as clean fill for the power block foundations. Excess construction debris is trucked off site as an alternative to onsite disposal. The excavations will be regraded such that the power block area will have a final contour consistent with adjacent surroundings.
The existing electrical switchyard and access roads will remain in support of the electrical transmission and distribution system. The site access road will be left intact.
3.6 ASSUMPTIONS The following are the major assumptions made in the development of the estimates for decommissioning the site.
3.6.1 Estimating Basis The study follows the principles of ALARA through the use of work duration adjustment factors. These factors address the impact of activities such as radiological protection instruction, mock-up training, and the use of respiratory protection and protective clothing. The factors lengthen a task's duration, increasing costs and lengthening the overall schedule. ALARA planning is considered in the costs for engineering and planning, and in the development of activity specifications and detailed procedures. Changes to worker exposure limits may impact the decommissioning cost and project schedule.
3.6.2 Labor Costs The craft labor required to decontaminate and dismantle the nuclear units will be acquired through standard site contracting practices. The current cost of labor at the site is used as an estimating basis. Costs for site administration, operations, construction, and maintenance personnel are based upon average salary information provided by FPL.
FPL will hire a Decommissioning Operations Contractor (DOC) to manage the decommissioning. The licensee will provide site security, radiological health and safety, quality assurance and overall site administration during the decommissioning and demolition phases.
Contract personnel will provide engineering services, e.g., for preparing the activity specifications, work procedures, activation, and structural analyses, under the direction of the owner.

No costs have been included for this activity.
Security, while reduced from operating levels, is maintained throughout the decommissioning for access control, material control, and to safeguard the spent fuel.
3.6.3 Design Conditions Any fuel cladding failure that occurred during the lifetime of the plant is assumed to have released fission products at sufficiently low levels that the buildup of quantities of long-lived isotopes (e.g., 137 Cs, 90Sr, or transuranics) has been prevented from reaching levels exceeding those that permit the major NSSS components to be shipped under current transportation regulations and disposal requirements.
The curie contents of the vessel and internals at final shutdown are derived from those listed in NUREG/CR-3474.[ 23] Actual estimates are derived from the curie/gram values contained therein and adjusted for the different mass of the Turkey Point components, projected operating life, and different periods of decay. Additional short-lived isotopes were derived from NUREG/CR-0130[ 2 4] and NUREG/CR-0672,[25]                  and benchmarked to the long-lived values from NUREG/CR-3474.
The control elements are disposed of along with the spent fuel, i.e., there is no additional cost provided for their disposal.
This study assumes that contamination (activation) of the containment building structure is confined to the biological shield. It should be noted that more extensive activation (at very low levels) of the interior structures within containment has been detected at several reactors and the owners have elected to dispose of the affected material at a controlled facility rather than reuse the material as fill on site or send it to a landfill. The ultimate disposition of the material removed from the reactor building will depend upon the site release criteria selected, as well as the designated end use for the site.
Contaminated Soil The estimates include an allowance for the remediation of contaminated soil from the reactor closure head replacement (approximately 14,310 cubic feet). Remediation and disposal of 59,300 cubic feet of contaminated soil/grass like material is also included.

3.6.4 General Transition Activities Existing warehouses are cleared of non-essential material and remain for use by FPL and its subcontractors. The plant's operating staff performs the following activities at no additional cost or credit to the project during the transition period:
Drain and collect fuel oils, lubricating oils, and transformer oils for recycle and/or sale.
o  Drain and collect acids, caustics, and other chemical stores for recycle and/or sale.
o  Process operating waste inventories; the disposal of operating wastes during this initial period is not considered a decommissioning expense.
Scrap and Salvage The existing plant equipment is considered obsolete and suitable for scrap as deadweight quantities only. FPL will make economically reasonable efforts to salvage equipment following final plant shutdown.
However, dismantling techniques assumed by TLG for equipment in this analysis are not consistent with removal techniques required for salvage (resale) of equipment. Experience has indicated that some buyers wanted equipment stripped down to very specific requirements before they would consider purchase. This required expensive rework after the equipment had been removed from its installed location. Since placing a salvage value on this machinery and equipment would be speculative, and the value would be small in comparison to the overall decommissioning expenses, this analysis does not attempt to quantify the value that an owner may realize based upon those efforts.
It is assumed, for purposes of this analysis, that any value received from the sale of scrap generated in the dismantling process would be more than offset by the on-site processing costs. The dismantling techniques TLG Services, Inc.

Turkey PointNuclearPlant, Units 3 and 4                   Document F02-1630-002, Rev. 0 DecommissioningCost Analysis                                     Section 3, Page 18 of 60 assumed in the decommissioning estimates do not include the additional cost for size reduction and preparation to meet "furnace ready" conditions. For example, the recovery of copper from electrical cabling may require the removal and disposition of any contaminated insulation, an added expense. With a volatile market, the potential profit margin in scrap recovery is highly speculative, regardless of the ability to free release this material. This assumption is an implicit recognition of scrap value in the disposal of clean metallic waste at no additional cost to the project.
Furniture, tools, mobile equipment such as forklifts, trucks, bulldozers, and other property is removed at no cost or credit to the decommissioning project. Disposition may include relocation to other facilities. Spare parts are also made available for alternative use.
Energy For estimating purposes, the plant is assumed to be de-energized, with the exception of those facilities associated with spent fuel storage.
Replacement power costs are used to calculate the cost of energy consumed during decommissioning for tooling, lighting, ventilation, and essential services.
Insurance Costs for continuing coverage (nuclear liability and property insurance) following cessation of plant operations and during decommissioning are included and based upon current operating premiums. Reductions in premiums, throughout the decommissioning process, are based upon the guidance and the limits for coverage defined in the NRC's proposed rulemaking "Financial Protection Requirements for Permanently Shutdown Nuclear Power Reactors."[26] The NRC's financial protection requirements are based on various reactor (and spent fuel) configurations.
Taxes Property taxes assessed during decommissioning are considered a decommissioning cost. From the time Unit 3 ceases operation to the end of year 2033 (the year in which Unit 4 ceases operation), taxes for the site are assumed to be assessed on the land value only (assuming no significant value for the site structures). After 2033, the tax charged to decommissioning is reduced to the portion of the tax applicable to only TLG Services,Inc.

This assessment (split 50/50 between the units) continues to be applied until the site is released for unrestricted use.
Site Modifications The perimeter fence and in-plant security barriers will be moved, as appropriate, to conform to the Site Security Plan in force during the various stages of the project.
Site Restoration The Intake and Discharge canals remain in place. Circulating water structures are removed and the canal bank restored. Structures to be removed include but are not limited to the containment, fuel handling, auxiliary, control, radwaste solidification, diesel generator, and turbine buildings.
3.7 COST ESTIMATE 

==SUMMARY==

Schedules of expenditures are provided in Tables 3.1 through 3.4 for the DECON and SAFSTOR alternatives. The tables delineate the cost contributors by year of expenditures as well as cost contributor (e.g., labor, materials, and waste disposal).
Additional tables in Appendices C and D provide detailed cost elements. The cost elements are also assigned to one of three subcategories: "License Termination,"
     "Spent Fuel Management," and "Site Restoration." The subcategory "License Termination" is used to accumulate costs that are consistent with "decommissioning" as defined by the NRC in its financial assurance regulations (i.e., 10 CFR &sect;50.75). The cost reported for this subcategory is generally sufficient to terminate the plant's operating license, recognizing that there may be some additional cost impact from spent fuel management.
The "Spent Fuel Management" subcategory contains costs anticipated to be incurred once the nuclear units cease operation for the off-loading of the pools either directly to the DOE or to the ISFSI for interim storage, and the eventual transfer of dry shielded canisters from the ISFSI to the DOE. Costs are also included for the operation of the ISFSI until such time that the transfer of all fuel from this facility to an off-site location (e.g., geologic repository) is complete.

Turkey PointNuclearPlant, Units 3 and 4                    Document F02-1630-002, Rev. 0 DecommissioningCost Analysis                                     Section 3, Page 20 of 60 "Site Restoration" is used to capture costs associated with the dismantling and demolition of buildings and facilities demonstrated to be free from contamination. This includes structures never exposed to radioactive materials, as well as those facilities that have been decontaminated to appropriate levels. Structures are removed to a depth of three feet and backfilled to conform to local grade.
As discussed in Section 3.4.1, it is not anticipated that the DOE will accept the GTCC waste prior to completing the transfer of spent fuel. Therefore, the cost of GTCC disposal is shown in the final year of ISFSI operation (for the DECON alternative). While designated for disposal at the geologic repository along with the spent fuel, GTCC waste is still classified as low-level radioactive waste and, as such, included as a "License Termination" expense.
Decommissioning costs are reported in 2010 dollars. Costs are not inflated, escalated, or discounted over the period of expenditure (or projected lifetime of the plant). The schedules are based upon the detailed activity costs reported in Appendices C and D, along with the timeline presented in Section 4.
The "Burial" column contains costs for the processing of low-level radioactive waste, as well as for the controlled disposal of material that cannot be recovered (released for unrestricted use). Since the following tables are often used in escalation analyses, costs associated with the disposition of GTCC have been reassigned to the "Other" column, commensurate with contractual payments for a one-time disposal service, although the cost is still reported in the "LLRW Disposal Costs" column in Appendices C and D and as a "Waste Disposal" cost in the summary tables (i.e., on pages xvii, xviii, 6-4 and 6-5).
    "Off-site Waste Processing," separately reported in the summary tables, has been included in the "Burial" column as well.

On March 31, 2009, FPL executed a Settlement Agreement with the DOE and the Department of Justice (DoJ). In the Agreement, FPL settled the lawsuit in exchange for payments. The payments are intended to cover those costs incurred for managing and storing the spent fuel that it would not have incurred but for DOE's delay in performance.
While the DOE is responsible for the costs incurred until it fulfills its obligation, certain assumptions are needed to assess the financial impact on the previously identified decommissioning cost scenarios. The assumptions and methodology employed to quantify the expected level of compensation are as follows:
: 1. DOE Acceptance Obligations are defined based on the 1995 Acceptance Priority Ranking & Annual Capacity Report Table 1 acceptance rate from Year 1 to Year 10, with a continued steady state acceptance rate of 900 metric tons of uranium (MTU) per year until December 31, 2014 and 2,100 MTU/year thereafter as per the Settlement Agreement.
: 2. At the time the aggregate MTUs actually accepted by the DOE equals the aggregate MTUs allocated to FPL under the 1995 Acceptance Priority Ranking & Annual Capacity Report, the DOE's compensation obligation ceases.
: 3. The pickup of commercial fuel is assumed to begin in the year 2030. The first fuel from St. Lucie is expected to be transferred to the DOE in 2032, again assuming commercial fuel is accepted on an oldest fuel first basis.*
basis.*
The rate of transfer was based upon an annual acceptance capacity at the geologic repository of 3,000 metric tons.
DOE's contracts with utilities order the acceptance of spent fuel from utilities based upon the oldest fuel receiving the highest priority. While DOE's acceptance priority ranking is based on the date that spent nuclear fuel was permanently discharged, with the oldest spent nuclear fuel, on an industry-wide basis, given the higher priority, the generator has the right to determine which spent nuclear fuel is delivered, provided that it is in compliance with the Standard Contract. DOE contracts also provide mechanisms for altering the oldest fuel first allocation scheme, including emergency deliveries, exchanges of allocations amongst utilities and the option of providing priority acceptance from permanently shutdown nuclear reactors.

Annual Capacity Report is based upon an earlier start date (1998), but a lower rate of acceptance than that considered in the Turkey Point decommissioning analysis. As shown in Table 3.5, the two different pickup rates would achieve the same level of performance (equivalent number of Turkey Point spent fuel assemblies received by the DOE) in the year 2059 (approximately      thirteen     years  before   the   ISFSI      would     be decommissioned). Under the terms of the Settlement Agreement, if the DOE follows the pickup rate, its compensation obligation would terminate when this milestone is reached. Under this scenario, the DOE would provide no compensation after 2059.
: 4. This analysis addresses only those costs identified as spent fuel management costs in the decommissioning cost analysis (as delineated in the detailed cost tables in Appendix C and D). While the estimates do assign costs to spent fuel management during the active decommissioning period, the cost elements are generally limited in scope to the direct costs associated with purchasing DSCs and HSMs, loading and packaging the spent fuel into the canisters for long-term storage at the plant's ISFSI (or into TADs for direct transfer to the DOE). No attempt was made, for this analysis, to identify any additional ISFSI related costs during this time period that may also be eligible for reimbursement by DOE under the Agreement.
As shown on the graph at the bottom of Table 3.5, it is projected that the DOE will meet its obligation for cumulative acceptance of spent fuel in the year 2059, based upon the assumptions delineated in the decommissioning cost analysis. Costs incurred for spent fuel management prior to this time (conservatively, December 31, 2058) can be expected to be reimbursed. Costs incurred after that time would not be eligible. Each year, the claim requesting the prior year's costs is submitted for payment on or before April 30.
The activities (at a minimum), identified in the decommissioning cost study and expected to be eligible for reimbursement (depending upon the timing of the activities) are identified below.

However, they will be recovered on an ongoing basis (i.e., the year after expenditure). Tables 3.6 and 3.7 identify the income stream that can be expected to offset spent fuel management expenses for the decommissioning scenarios. Under the current assumptions, costs incurred in the year 2059 and beyond would not be eligible for reimbursement.
Table 3.8 identifies cost to decommission the ISFSI. While the costs are incurred after 2059, they may also be reimbursable since ISFSI construction was in response to delays in the timely removal of spent fuel from the site.

: 4. SCHEDULE ESTIMATE The schedules for the decommissioning scenarios considered in this study follow the sequences presented in the AIF/NESP-036 study, with minor changes to reflect recent experience and site-specific constraints. In addition, the scheduling has been revised to reflect the spent fuel management plan described in Section 3.5.1.
A schedule or sequence of activities for the DECON alternative is presented in Figure 4.1. The scheduling sequence is based on the fuel being removed from the spent fuel pools within five and one half years. The key activities listed in the schedule do not reflect a one-to-one correspondence with those activities in the cost tables, but reflect dividing some activities for clarity and combining others for convenience. The schedule was prepared using the "Microsoft Project Professional 27 2007" computer software.[ ]
4.1   SCHEDULE ESTIMATE ASSUMPTIONS The schedule reflects the results of a precedence network developed for the site decommissioning activities, i.e., a PERT (Program Evaluation and Review Technique) Software Package. The work activity durations used in the precedence network reflect the actual man-hour estimates from the cost table, adjusted by stretching certain activities over their slack range and shifting the start and end dates of others. The following assumptions were made in the development of the decommissioning schedule:
0 The fuel handling area is isolated until such time that all spent fuel has been discharged from the spent fuel pools to the DOE or to the ISFSI for interim storage. Decontamination and dismantling of the storage pools is initiated once the transfer of spent fuel is complete (DECON alternative).
* All work (except vessel and internals removal) is performed during an 8-hour workday, 5 days per week, with no overtime. There are eleven paid holidays per year.
a Reactor and internals removal activities are performed by using separate crews for different activities working on different shifts, with a corresponding backshift charge for the second shift.
a Multiple crews work parallel activities to the maximum extent possible, consistent with optimum efficiency, adequate access for cutting, removal and laydown space, and with the stringent safety measures necessary during demolition of heavy components and structures.

4.2 PROJECT SCHEDULE The period-dependent costs presented in the detailed cost tables are based upon the durations developed in the schedules for decommissioning. Durations are established between several milestones in each project period; these durations are used to establish a critical path for the entire project. In turn, the critical path duration for each period is used as the basis for determining the period-dependent costs. A second critical path is shown for the spent fuel storage period, which determines the release of the fuel storage area for final decontamination.
Project timelines are provided in Figures 4.2 and 4.3, with milestone dates based on the 2032 and 2033 shutdown dates for Units 3 and 4, respectively. The fuel pools are emptied approximately five and one half years after shutdown, while ISFSI operations continue until the DOE can complete the transfer of assemblies to its geologic repository. Deferred decommissioning in the SAFSTOR alternative is assumed to commence so that the operating license is terminated within a 60-year period from the cessation of plant operations.

: 5. RADIOACTIVE WASTES The objectives of the decommissioning process are the removal of all radioactive material from the site that would restrict its future use and the termination of the NRC license. This currently requires the remediation of all radioactive material at the site in excess of applicable legal limits. Under the Atomic Energy Act,[28] the NRC is responsible for protecting the public from sources of ionizing radiation. Title 10 of the Code of Federal Regulations delineates the production, utilization, and disposal of radioactive materials and processes. In particular, Part 71 defines radioactive material as it pertains to transportation and Part 61 specifies its disposition.
Most of the materials being transported for controlled burial are categorized as Low Specific Activity (LSA) or Surface Contaminated Object (SCO) materials containing Type A quantities, as defined in 49 CFR Parts 173-178. Shipping containers are required to be Industrial Packages (IP-1, IP-2 or IP-3, as defined in 10 CFR
&sect;173.411). For this study, commercially available steel containers are presumed to be used for the disposal of piping, small components, and concrete. Larger components can serve as their own containers, with proper closure of all openings, access ways, and penetrations.
The volumes of radioactive waste generated during the various decommissioning activities at the site are shown on a line-item basis in Appendices C and D, and summarized in Tables 5.1 and 5.2. The quantified waste volume summaries shown in these tables are consistent with 10 CFR Part 61 classifications. The volumes are calculated based on the exterior dimensions for containerized material and on the displaced volume of components serving as their own waste containers.
The reactor vessel and internals are categorized as large quantity shipments and, accordingly, will be shipped in reusable, shielded truck casks with disposable liners.
In calculating disposal costs, the burial fees are applied against the liner volume, as well as the special handling requirements of the payload. Packaging efficiencies are lower for the highly-activated materials (greater than Type A quantity waste),
where high concentrations of gamma-emitting radionuclides limit the capacity of the shipping canisters.
No process system containing/handling radioactive substances at shutdown is presumed to meet material release criteria by decay alone (i.e., systems radioactive at shutdown will still be radioactive over the time period during which the decommissioning is accomplished, due to the presence of long-lived radionuclides).
37 While the dose rates decrease with time, radionuclides such as 1 Cs will still control the disposition requirements.

Material that is considered potentially contaminated when removed from the radiological controlled area is sent to processing facilities in Tennessee for conditioning and disposal. Heavily contaminated components and activated materials are routed for controlled disposal. The disposal volumes reported in the tables reflect the savings resulting from reprocessing and recycling.
For purposes of constructing the estimates, FPL's current cost for disposal at the EnergySolutions facility was used. Separate rates were used for containerized waste and large components, including the steam generators and reactor coolant pump motors. Demolition debris including miscellaneous steel, scaffolding, and concrete was disposed of at a bulk rate. The decommissioning waste stream also included resins and dry active waste.
Since EnergySolutions is not currently able to receive the more highly radioactive components generated in the decontamination and dismantling of the reactor, disposal costs for the Class B and C material were based upon the last published rate schedule for non-compact waste for the Barnwell facility (as a proxy), adjusted for escalation of the Atlantic Compact rates. Additional surcharges were included for activity, dose rate, and/or handling added as appropriate for the particular package.

: 6. RESULTS The analysis to estimate the costs to decommission Turkey Point relied upon the site-specific, technical information developed for a previous analysis prepared in 2005, updated to reflect current assumptions pertaining to the disposition of the nuclear station and relevant industry experience in undertaking such projects.
While not an engineering study, the estimates provide FPL with sufficient information to assess their financial obligations, as they pertain to the eventual decommissioning of the nuclear station.
The estimates described in this report are based on numerous fundamental assumptions, including a 60-year operating life, regulatory requirements, project contingencies, low-level radioactive waste disposal practices, high-level radioactive waste     management       options,   and site    restoration   requirements.      The decommissioning scenarios assume continued operation of the station's spent fuel pools for a minimum of five and one half years following the cessation of operations for continued cooling of the assemblies.
The cost projected to promptly decommission the station, manage the spent fuel, and restore the site, is estimated to be $1,386.2 million. The majority of this cost (approximately 67.3%) is associated with the physical decontamination and dismantling of the nuclear plant so that the operating license can be terminated.
Another 27.0% is associated with the management, interim storage, and eventual transfer of the spent fuel. The remaining 5.7% is for the demolition of the designated structures and limited restoration of the site.
The cost projected for deferred decommissioning (SAFSTOR) is estimated to be
$1,770.0 million. The majority of this cost (approximately 75.8%) is associated with placing the plant in storage, ongoing caretaking of the plant during dormancy, and the eventual physical decontamination and dismantling of the nuclear plant so that the operating license can be terminated. Another 19.6% is associated with the management, interim storage, and eventual transfer of the spent fuel. The remaining 4.6% is for the demolition of the designated structures and limited restoration of the site.
The primary cost contributors, identified in Tables 6.1 and 6.2, are either labor-related or associated with the management and disposition of the radioactive waste.
Program management is the largest single contributor to the overall cost. The magnitude of the expense is a function of both the size of the organization required to manage the decommissioning, as well as the duration of the program. It is assumed, for purposes of this analysis, that FPL will hire a Decommissioning Operations Contractor (DOC) to manage the, decommissioning. The owner will TLG Services,Inc.

Turkey PointNuclearPlant, Units 3 and 4                    Document F02-1630-002, Rev. 0 DecommissioningCost Analysis                                         Section 6, Page 2 of 5 provide site security, radiological health and safety, quality assurance and overall site administration during the decommissioning and demolition phases. Contract personnel will provide engineering services, e.g., for preparing the activity specifications, work procedures, activation, and structural analyses, under the direction of the owner. The size and composition of the management organization varies with the decommissioning phase and associated site activities. However, once the operating licenses are terminated, the staff is substantially reduced for the conventional demolition and restoration of the site, and the long-term care of the spent fuel (for the DECON alternative).
As described in this report, the spent fuel pools will remain operational for a minimum of five and one half years following the cessation of operations. The pools will be isolated and an independent spent fuel island created. This will allow decommissioning operations to proceed in and around the pool area. Over the five and one half-year period, the spent fuel will be packaged into transportable canisters for loading into a DOE-provided transport cask or relocation to the ISFSI.
The cost for waste disposal includes only those costs associated with the controlled disposition of the low-level radioactive waste generated from decontamination and dismantling activities, including plant equipment and components, structural material, filters, resins and dry-active waste. As described in Section 5, disposition of the majority of the low-level radioactive material requiring controlled disposal is at the EnergySolutions' facility. Highly activated components, requiring additional isolation from the environment (GTCC), are packaged for geologic disposal. The cost of geologic disposal is based upon a cost equivalent for spent fuel.
A significant portion of the metallic waste is designated for additional processing and treatment at an off-site facility. Processing reduces the volume of material requiring controlled disposal through such techniques and processes as survey and sorting, decontamination, and volume reduction. The material that cannot be unconditionally released is packaged for controlled disposal at one of the currently operating facilities. The cost identified in the summary tables for processing is all-inclusive, incorporating the ultimate disposition of the material.
Removal costs reflect the labor-intensive nature of the decommissioning process, as well as the management controls required to ensure a safe and successful program.
Decontamination and packaging costs also have a large labor component that is based upon prevailing wages. Non-radiological demolition is a natural extension of the decommissioning process. With a work force mobilized to - support decommissioning operations, non-radiological demolition can be an integrated activity and a logical expansion of the work being performed in the process of terminating the operating license. Prompt demolition reduces future liabilities and TLG Services,Inc.

The reported cost for transport includes the tariffs and surcharges associated with moving large components and/or overweight shielded casks overland, as well as the general expense, e.g., labor and fuel, of transporting material to the destinations identified in this report. For purposes of this analysis, material is primarily moved overland by truck.
Decontamination is used to reduce the plant's radiation fields and minimize worker exposure. Slightly contaminated material or material located within a contaminated area is sent to an off-site processing center, i.e., this analysis does not assume that contaminated plant components and equipment can be decontaminated for uncontrolled release in-situ. Centralized processing centers have proven to be a more economical means of handling the large volumes of material produced in the dismantling of a nuclear plant.
License termination survey costs are associated with the labor intensive and complex activity of verifying that contamination has been removed from the site to the levels specified by the regulating agency. This process involves a systematic survey of all remaining plant surface areas and surrounding environs, sampling, isotopic analysis, and documentation of the findings. The status of any plant components and materials not removed in the decommissioning process will also require confirmation and will add to the expense of surveying the facilities alone.
The remaining costs include allocations for heavy equipment and temporary services, as well as for other expenses such as regulatory fees and the premiums for nuclear insurance. While site operating costs are greatly reduced following the final cessation of plant operations, certain administrative functions do need to be maintained either at a basic functional or regulatory level.,
