Subject:

Response to Requests for Additional Information By letter dated October 6, 2009, the Nuclear Regulatory Commission Staff (NRC) issued Requests for Additional Information (RAIs) related to the decommissioning funding status for NextEra Energy's ownership interests in the Duane Arnold Energy Center (DAEC). NextEra Energy's responses to the Staff's RAIs are provided in the Enclosure to this letter.

Should you have questions regarding NextEra Energy's responses to the Staff's RAIs, please contact Mitchell Ross, Vice President and General Counsel - Nuclear at 561-691-7126, or Lisa Fuca, Nuclear Business Operations, at 561-691-7604.

Sincerely yours, Mano Nazar Senior Vice Presiden, Nuclear and Chief Nuclear Office, Enclosure A4w0(

an FPL Group company

US Nuclear Regulatory Commission L-2009-256 Enclosure Page 1 of 4 Enclosure - NRC Staff's Requests for Additional Information - Duane Arnold Energy Center The Nuclear Regulatory Commission (NRC) staff has reviewed your submittal, dated July 27, 2009, outlining FPL Energy Duane Arnold, LLC's (FPL Energy) proposedplan of action to cover deficiencies in providing decommissioning funding assurance discovered in its 70 percent ownership of Duane Arnold Energy Center (DAEC) Biennial Decommissioning Funding Report that was submitted on March 27, 2009. At that time, the NRC staff estimated a projected deficiency in decommissioning funding assurance of approximately $48 million in total. This reflects the review of all three owners of DAEC, for decommissioning funding assurance.

In the July 27, 2009, submittal, FPL Energy states that the decommissioning trust fund balance as of June 30, 2009, has grown to $167.5 million, an increase of $3.9 million from the December 31, 2008 balance indicated in the Biennial Decommissioning Funding Report that was submitted on or about March 31, 2009, by FPL Energy Duane Arnold, LLC.

FPL Energy has also proposed the use of a Parent Company Guarantee (PCG), based on a value derived by discounting the Minimum Decommissioning Funding Formula amount from the projected value at the time of permanent secession of operations, to a present value at the end of calendar year 2009. FPL Energy believes that the combination of the increased decommissioning trust fund balance as of June 30, 2009, along with the proposed discounted PCG, provides decommissioning funding assurance.

On July 27, 2009, FPL submitted a plan on behalf of the licensed owners, FPL Energy, 70 percent owner, and Central Iowa Power Cooperative (CIPCO), 20 percent owner, as part of the concurrent 2009 Biennial Decommissioning Review process, which describes how and when it intends to make adjustments to financial assurance mechanisms such that any shortfalls in decommissioning funding assurancefor DAEC are covered.

On page 2 of the decommissioning funding plan submitted, FPL Energy DA stated:

In order to address the funding difference for DAEC, FPL Energy will cause FPL Group Capital Inc. to amend the existing decommissioning funding parent (company) guaranty for $93 million to increase the value of that parent (company) guaranty to $132.5 million, [which is based on a] present value of NRC Minimum Calculationpursuantto 10 CFR 50.75.

10 CFR 50.75 (b)(1) states:

(b) Each power reactorapplicant for or holder of an operating license, and each applicant for a combined license under subpart C of 10 CFR part 52 for a production or utilization facility of the type and power level specified in paragraph (c) of this section shall submit a decommissioning report, as required by section 50.33(k).

(1) For an applicant for or holder of an operating license under part 50, the report must contain a certification that financial assurance for decommissioning will be (for a license applicant), or has been (for a license holder), provided in an amount which may be more, but not less, than the amount stated in the table in paragraph(c)(1) of this section adjusted using a rate at least equal to that stated in paragraph (c)(2) of this section.

(Emphasis added.)

US Nuclear Regulatory Commission L-2009-256 Enclosure Page 2 of 4 Question 1 On Enclosure 4 of the July 27, 2009, submittal, CIPCO stated that a Real Rate of Return of four percent is assumed. Please provide the necessary evidence that allows CIPCO to use an assumed Real Rate of Return of four percent by the appropriateregulatory authority.

Central Iowa Power Cooperative's Response to RAI 1:

CIPCO is a public corporation incorporated under Chapter 499 Iowa Code (2009). CIPCO has the authority and is required to fix, establish, and collect adequate rates and other charges for electrical energy or services sold or furnished by it. CIPCO is accordingly authorized to establish its own rates and other charges through which it can recover its cost of service.

CIPCO is governed by a 13 member Board of Directors that are elected by the CIPCO members. The Board of Directors is the rate making authority for CIPCO. CIPCO rates are not regulated by any state or federal authority. In a Board Resolution dated October 27, 2009, the CIPCO Board of Directors resolved that the rates and other charges for electrical energy services and the decommissioning fund be established assuming a real rate of return on the decommissioning fund of four percent.

Question 2 Please provide a status of the remaining 10 percent owner of DAEC.

Corn Belt Power Cooperative's Response to RAI 2:

Corn. Belt Power Cooperative is a public corporation incorporated under Chapter 499 Iowa Code (2009). The Cooperative has the authority and is required to fix, establish, and collect adequate rates and other charges for electrical energy or services sold or furnished by it. Corn Belt is governed by an 11 member Board of Directors who are elected by its members. The Corn Belt Board of Directors is accordingly authorized to establish its own rates and other charges through which it can recover its cost of service and is the rate making authority for the Cooperative. The Cooperative's rates are not regulated by any state or federal authority.

In a Board Resolution dated October 30, 2009, the Corn Belt Board of Directors resolved that the rates and other charges for electrical energy services and the decommissioning fund be established assuming a real rate of return on the decommissioning fund of three percent.

An updated accounting of Corn Belt's trust balance and planned future contributions is provided in the response to RAI 3.

Question 3 NRC recognizes that. if approximately $132.5 million were deposited in cash into the prepaid account, the, increased balance would provide adequate financial assurance, as of June 30, 2009. The reason is that actual funds in a prepaid account can generate earnings.

However, FPL's plan to provide .a PCG in the amount of $132.5 million does not meet the requirements of section 50.75(e)(1)(i). The PCG is a promise by the parent company to pay the decommissioning obligations of. the licensee in the event the licensee fails to pay for decommissioning costs. By its nature, the PCG has no funds from which earnings can be

US Nuclear Regulatory Commission L-2009-256 Enclosure Page 3 of 4 decommissioning costs. By its nature, the PCG has no funds from which earnings can be generated. Your plan would generate earnings only on. the actual balance in the account. The sum of the $165.7 million trust fund balance plus earnings on the balance plus a $132.5 million PCG would not cover the minimum NRC requirement of section 50.75(c), as of July 31, 2009.

In view of the above, provide a revised plan to cover the projected shortfall using a method that conforms to one of the methods provided in section 50.75.

NextEra's Response to RAI 3:

NextEra does not concede that the NRC's position regarding the use of the present value of the NRC formula minimum amount is correct. However, NextEra presents the following revised plan for demonstrating funding assurance that does not involve a present value calculation and instead relies upon its preliminary site-specific estimate of the cost to decommission the Duane Arnold Energy Center (DAEC) using the SAFSTOR method, which complies with 10 CFR 50.75.

NextEra has not made a final determination of the actual decommissioning approach for DAEC, but the SAFSTOR option has been selected for the purpose of demonstrating the adequacy of DAEC's decommissioning funding. NextEra may choose a different decommissioning option in the future, recognizing that the chosen option must meet NRC requirements for decommissioning funding. Specifically, renewal of the DAEC operating license may lead NextEra to change its planned decommissioning methods for funding assurance purposes.

NextEra filed a license renewal application for DAEC on September 30, 2008.

Pursuant to 10 CFR 50.75(e)(1)(i), "A licensee that has prepaid funds based on a site specific estimate under § 50.75(b)(1) of this section may take credit for projected earnings on the prepaid decommissioning trust funds, using up to a 2 percent annual real rate of return from the time of future funds' collection through the projected decommissioning period, provided that the site-specific estimate is based on a period' of safe storage that is specifically described in the estimate." Thus, a site-specific cost estimate may be used for demonstrating decommissioning funding assurance, provided that "the NRC-required cost estimate for decommissioning costs as defined in 10 CFR 50.2 is equal to or greater than the amount stated in the formulas in 10 CFR 50.75(c)(1) and (2)." (Regulatory Guide 1.159, section 1.1.1; Draft Regulatory Guide-1229, section 1.1.1.)

On February 19, 2009, NextEra submitted a site-specific decommissioning cost estimate to the NRC as part of its preliminary decommissioning cost estimate and spent fuel management plan filing required by 10 CFR 50.75(f)(3) and 10 CFR 50.54(bb) (Accession Nos. ML090550968 and ML090570189). Scenario 2 of the DAEC site-specific estimate considers the costs to decommission the facility assuming (1) no renewal of the facility operating license, and (2) the use of a SAFSTOR period. NextEra's revised plan for demonstrating decommissioning funding assurance is based upon this scenario - a period of safe storage until 2068, at which time decommissioning activities will commence.

Appendix E to the DAEC site-specific estimate (pages 164-65 of 190) provides the annual license termination costs for this scenario in 2008 dollars. Section 1.4.3 of Regulatory Guide 1.159 (and Draft Regulatory Guide-1229) states that site specific cost estimates should be adjusted at least once a year to reflect the impact of inflation. Section 1.4.1 states that licensees may use standard, measures of price indexing, such as the annual Consumer Price Index (CPI) published by the Bureau of Labor Statistics to adjust site-specific cost estimates.

The CPI Detailed Report for September 2009 shows negative growth in the CPI over the previous 12-month period. For this analysis, NextEra did not adjust the cost estimate downward

US Nuclear Regulatory Commission L-2009-256 Enclosure Page 4 of 4 to reflect the deflation experienced over the past year. Instead, the cost estimate provided below conservatively retains the use of 2008 dollars.

The decommissioning trust funds for DAEC have increased since December 31, 2008. As of September 30, 2009, the total decommissioning trust fund balance including the shares of all three joint owners is approximately $232,709,000, compared to the December 31, 2008 balance of $203,073,403. Table 1 utilizes the September 30, 2009 DAEC decommissioning trust fund balance in lieu of the December 31, 2008 balance. In Table 1, the decommissioning trust fund ending balance is escalated each year by the 2% real rate of return allowed pursuant to 10 CFR 50.75(e)(1)(i) for NextEra's share, and by the 3% and 4% real rate of return authorized by Corn Belt's and CIPCO's rate-setting authorities, respectively, as allowed under 10 CFR 50.75(e)(i) and discussed in the answers to RAIs 1 and 2 above. After the annual escalation, the estimated annual costs are subtracted from the annual total decommissioning fund balance and the planned contributions of CIPCO and Corn Belt are added. Table 1 includes only license termination costs and does not include spent fuel management or non-radiological greenfield costs.

As can be seen from the information provided in Table 1, the required funding for a SAFSTOR decommissioning, approximately $579 million, is greater than the current (September 30, 2009)

NRC formula amount per 10 CFR 50.75(b) and (c) of $507,291,842, and therefore, the site-specific analysis complies with the NRC's position outlined in Regulatory Guide 1.159 section 1.1.1 that a site-specific cost estimate may only be used if it is equal to or greater than the NRC formula amount.

This SAFSTOR analysis demonstrates that when the September 30, 2009 decommissioning trust fund balance is escalated at the allowable rates and compared against the annual figures for the SAFSTOR period studied in the DAEC preliminary decommissioning cost estimate, a significant surplus would remain at the end of the decommissioning project. Accordingly, NextEra concludes that no further action is required at this time to demonstrate adequate funding assurance for decommissioning DAEC.

As reflected in the March 27, 2009 Biennial Funding Status Report and the July 27, 2009 Decommissioning Funding Status Report and Financial Assurance Plan, NextEra currently has a $93 million parent guaranty providing partial decommissioning funding assurance. Using the SAFSTOR approach, NextEra's parent guaranty would no longer be required. Through this filing, NextEra is seeking NRC approval of its SAFSTOR decommissioning funding assurance mechanism and will maintain its parent guaranty in place pending NRC approval. Following NRC approval, and in accordance with its terms, NextEra's parent guaranty will remain in place until 120 days after NextEra or FPL Group Capital, Inc. provides notice to the NRC of its cancellation.
