SUMMARY
This report presents an estimate of the cost to decommission the Crystal River Unit 3 Nuclear Generating Plant (CR-3). The analysis relies upon site-specific, technical information from an earlier evaluation prepared in 2011,11] updated to reflect current assumptions pertaining to the disposition of the nuclear unit and relevant industry experience in undertaking such projects. This estimate has been prepared for Duke Energy Florida, Inc. (DEF), formerly known as Florida Power Corporation, to comply with the requirements of 10 CFR 50.82(a)(4)(i).
The current estimate is designed to provide DEF with sufficient information to assess its 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.
CR-3 has been safely shutdown since September 26, 2009, when the plant entered the Cycle 16 refueling outage to replace the steam generators. As of May 28, 2011, all fuel assemblies were removed from the reactor vessel and placed in the spent fuel pool for temporary storage. Certification of the permanent cessation of power operations and defueling was submitted to the Nuclear Regulatory Commission (NRC) on February 20, 2013.[21 DEF has announced its intention to decommission under the SAFSTOR alternative.
The currently projected total cost to decommission the nuclear unit, assuming the SAFSTOR alternative, is estimated at $1,180 million, as reported in 2013 dollars (DEF's share, as well as that of the nine minority owners). The cost includes the monies anticipated to be spent for operating license termination (radiological remediation), interim spent fuel storage and site restoration activities. The cost is based on several key assumptions in areas of regulation, component characterization, high-level radioactive waste management, low-level radioactive waste disposal, performance uncertainties (contingency) and site remediation and restoration requirements. The assumptions are discussed in more detail in this document.

Crystal River Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific DecommissioningCost Estimate Page vii of xx Decommissioning Alternatives and Regulations The ultimate objective of the decommissioning process is to reduce the inventory of contaminated and activated material to levels at or below the site release criteria so that the license can be terminated. The NRC (or Commission) provided initial decommissioning requirements in its rule adopted on June 27, 1988.[13 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 decommissioning rulemaking 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."1 4]
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."[15 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 decays to a level permitting unrestricted release of the property."[61 As with the SAFSTOR alternative, decommissioning is currently required to be completed within 60 years, although longer time periods will also be considered when necessary to protect public health and safety.
The 60-year restriction has limited the practicality for the ENTOMB alternative at commercial reactors that generate significant amounts of long-lived radioactive 3 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.

In 1997, the Commission 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 (e.g., 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.[71 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 estimate is also consistent with the recommendations of Regulatory Guide 1.202, issued in February 2005.[81 Basis of the Cost Estimate The decommissioning approach that has been selected by DEF for CR-3 is the SAFSTOR method. The primary objectives of the CR-3 decommissioning project are to remove the facility from service, reduce residual radioactivity to levels permitting unrestricted release, restore the site, perform this work safely, and complete the work in a cost effective manner. The selection of a preferred decommissioning alternative is influenced by a number of factors. These factors include the cost of each decommissioning alternative, minimization of occupational radiation exposure, availability of low-level waste disposal facilities, availability of a high-level waste (spent fuel) repository or Department of Energy (DOE) interim storage facility, regulatory requirements, and public concerns. In addition, 10 CFR 50.82(a)(3) requires decommissioning to be completed within 60 years of permanent cessation of operations.
Under the SAFSTOR methodology, the facility is placed in a safe and stable condition and maintained in that state, allowing levels of radioactivity to decrease through radioactive decay, followed by decontamination and dismantlement. After the safe 7 U.S. Code of Federal Regulations, Title 10, Parts 2, 50, and 51, "Decommissioning of Nuclear Power Reactors," Nuclear Regulatory Commission, Federal Register Volume 61, (P 39278 et seq.), July 29, 1996.

In accordance with 10 CFR 50.82(a)(9), a license termination plan (LTP) will be developed and submitted for NRC approval at least two years prior to termination of the license.
An Independent Spent Fuel Storage Installation (ISFSI) will be constructed adjacent to the power block. The spent fuel will be relocated from the auxiliary building to the ISFSI to await transfer to a DOE facility. Assuming priority pickup for the spent fuel from shutdown reactors, and based upon a 2032 start date, DEF anticipates that the removal of spent fuel from the site could be completed by the end of year 2036.
For purposes of this analysis, the plant remains in safe-storage until 2067, at which time it will be decommissioned and the site released for alternative use without restriction, i.e., the license is terminated within the required 60-year time period.
Methodology The primary goal of the decommissioning is the removal and disposal of the contaminated systems and structures so that the plant's operating license can be terminated. The analysis recognizes that spent fuel will be stored at the site in the plant's storage pool and/or in an ISFSI until such time that it can be transferred to the DOE. Consequently, the estimate includes those costs to manage and subsequently decommission the interim storage facilities.
The estimate is 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 methodology used to develop the estimate followed the basic approach originally presented in the AIF/NESP-036 study report, "Guidelines for Producing Commercial Nuclear Power Plant Decommissioning Cost Estimates,"1 91 and the DOE "Decommissioning Handbook."[' 01 These documents present a unit cost factor method for estimating decommissioning activity costs that simplifies the calculations. Unit factors for concrete removal ($/cubic yard), steel removal ($/ton),
and cutting costs ($/inch) were developed using local labor rates. The activity-dependent costs were then estimated with the item quantities (cubic yards and tons), developed from plant drawings and inventory documents. Removal rates and 9 T.S.

Means.[I"]
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.
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 analysis reflected lessons learned from TLG's involvement in the Shippingport Station decommissioning, completed in 1989, as well as 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 the technical challenges of decommissioning commercial nuclear units.
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."[12] The cost elements in the estimate 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 life of the project.

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 generally 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 Disposal Act" in 1980 and its Amendments of 1985, [131 the states became ultimately responsible for the disposition of low-level radioactive waste generated within their own borders.
With the exception of Texas, no new compact facilities have been successfully sited, licensed, and constructed. Construction of the Texas Compact disposal facility is now essentially complete and the facility was declared operational by the operator, Waste Control Specialists (WCS), in November 2011. The facility will be able to accept limited quantities of non-Compact waste; however, at this time the cost for non-Compact generators is being negotiated on an individual basis.
Disposition of the various waste streams produced by the decommissioning process considered all options and services currently available to DEF. The majority of the low-level radioactive waste designated for direct disposal (Class A[1 41) can be sent to EnergySolutions' facility in Clive, Utah. Therefore, disposal costs for Class A waste were based upon DEF's Life of Plant Agreement with EnergySolutions. This facility is not licensed to receive higher activity waste (Class B and C).
The WCS facility is able to receive the Class B and C waste. As such, for this analysis, Class B and C waste is assumed to be shipped to the WCS facility and disposal costs for the waste were based upon preliminary and indicative information on the cost for such from WCS (and intermediary processors such as Studsvik).
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 13 "Low-Level Radioactive Waste Policy Amendments Act of 1985," Public Law 99-240, January 15, 1986 14 Waste is classified in accordance with U.S. Code of Federal Regulations, Title 10, Part 61.55, "Licensing Requirements for Land Disposal of Radioactive Waste" TLG Services, Inc.

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 study, components that must be disposed of as GTCC waste would be packaged in the same canisters used for spent fuel. Because dismantlement would occur after the projected date for DOE acceptance of spent fuel and high level waste, for purposes of this study it is assumed that the canisters would be shipped directly to a DOE facility.
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 estimate reflects the savings from waste recovery/volume reduction.
High-Level Radioactive Waste Manaement Congress passed the "Nuclear Waste Policy Act" (NWPA) in 1982, assigning the federal government's long-standing responsibility for disposal of the spent nuclear fuel created by the commercial nuclear generating plants to the DOE. The DOE was to begin accepting spent fuel and high-level waste by January 31, 1998; however, to date no progress in the removal of spent fuel from commercial generating sites has been made.
Today, the country is at an impasse on high-level waste disposal, even with the iUcense Application for a geologic repository submitted by the DOE to the NRC in 2008. The current administration has cut the budget for the repository program while promising to "conduct a comprehensive review of policies for managing the back end of the nuclear fuel cycle ... and make recommendations for a new plan."[' 5 ]
Towards this goal, the administration appointed a Blue Ribbon Commission on America's Nuclear Future (Blue Ribbon Commission) to make recommendations for a new plan for nuclear waste disposal. The Blue Ribbon Commission's charter 15 Blue Ribbon Commission on America's Nuclear Future's Charter, http://cvbercemeterv.unt.edu/archive/brc/20120620215336/httR://brc.gov/index.php)?o=page/charter TLG Services, Inc.
Crystal River Unit 3 Nuclear Generating Plant Document No. P23-1"0-01,Rev. 0 Site-Specific Decommissioning Cost Estimate Page xiii of xx includes a requirement that it consider "jolptiona for safe storage of used nuclear fuel while final disposition pathways are selected and deployed."t6 On January 26, 2012, the Blue Ribbon Commission issued its "Report to the Secretary of Energy" containing a number of recommendations on nuclear waste disposal. Two of the recommendations that may impact decommissioning planning are:
S"[The United States [should] establish a program that leads to the timely development of one or more consolidated storage facilities"9 1 71 S"IT]he United States should undertake an integrated nuclear waste management program that leads to the timely development of one or more permanent deep geological facilities for the safe disposal of spent fuel and high-level nuclear waste."[Ns]
In January 2013, the DOE issued the "Strategy for the Management and Disposal of Used Nuclear Fuel and High-Level Radioactive Waste," in response to the recommendations made by the Blue Ribbon Commission and as "a framework for moving toward a sustainable program to deploy an integrated system capable of transporting, storing, and disposing of used nuclear fuel..."l'91 "With the appropriate authorizations from Congress, the Administration currently plans to implement a program over the next 10 years that:
" Sites, designs and licenses, constructs and begins operations of a pilot interim storage facility by 2021 with an initial focus on accepting used nuclear fuel from shut-down reactor sites;
" Advances toward the siting and licensing of a larger interim storage facility to be available by 2025 that will have sufficient capacity to provide flexibility in the waste management system and allows for acceptance of enough used nuclear fuel to reduce expected government liabilities; and 16 Ibid.

- Makes demonstrable progress on the siting and characterization of repository sites to facilitate the availability of a geologic repository by 2048."[201 In 2010, the government discontinued work on the review of the application to construct a geologic repository for spent nuclear fuel and high-level waste at Yucca Mountain. However, the US Court of Appeals for the District of Columbia Circuit recently issued a writ of mandamus (in August 2013) ordering NRC to comply with federal law and restart its review of DOE's Yucca Mountain repository license application.
Even with a favorable review, there is considerable uncertainty as to DOE's future actions on the growing backlog of spent fuel, even with the additional direction provided by the Blue Ribbon Commission. For purposes of this analysis, Duke Energy evaluated the feasibility of several spent fuel disposition scenarios, both near-term (e.g., 2021) and long-term (e.g., 2048), as well as a more moderate scenario.
For purposes of this estimate, the spent fuel management plan for the CR-3 spent fuel is based in general upon: 1) a 2032 start date for DOE initiating transfer of commercial spent fuel to a federal facility, 2) priority pickup for shutdown reactors, and 3) pickup based on the permanent shutdown date of the plant (oldest fuel first).
Assuming a maximum rate of transfer of 3,000 metric tons of uranium (MTU)/year, [211 and the aforementioned assumptions on spent fuel management, transfer of spent fuel from CR-3 to DOE would begin in 2035 and the spent fuel from CR-3 would be completely removed from the site by the end of 2036.
The NRC requires that licensees establish a program to manage and provide funding for the caretaking of all irradiated fuel at the reactor site until title of the fuel is transferred to the DOE. [221 Interim storage of the fuel, until the DOE has completed the transfer, will be in the auxiliary building's storage pool, as well as at an ISFSI to be constructed on the site. Once the wet storage pool is emptied, the auxiliary building can be prepared for long-term storage.
DEF's position is that the DOE has a contractual obligation to accept the spent fuel 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.

Crystal River Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific DecommissioningCost Estimate Page xv of xx 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 can substantially damage power block structures, potentially weakening the footings and structural supports. It is unreasonable to anticipate that these structures would be repaired and preserved after the radiological contamination is removed. Dismantling site structures with a work force already mobilized is more efficient and less costly than if the process is deferred. Consequently, this study assumes that site structures addressed by this analysis are removed to a nominal depth of three feet below the top grade of the embankment, wherever possible.
The cost for the site restoration of decontaminated and/or non-contaminated structures has been calculated and is separately presented as "Site Restoration" expenditures in this report.
Summary The cost to decommission CR-3 assumes the removal of all contaminated and activated plant components and structural materials such that DEF 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 storage facilities are also decommissioned.
The decommissioning scenario is 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 Appendix C.
The cost elements in the estimate are assigned to one of three subcategories: NRC License Termination, Spent Fuel Management, and Site Restoration. The subcategory "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). In situations where the long-term management of spent fuel is not an issue, the cost reported for this subcategory is generally sufficient to terminate the unit's operating license.
TLG Services, Inc.
Crystal River Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific Decommissioning Cost Estimate Page xvi of xx The "Spent Fuel Management" subcategory contains costs associated with the containerization and transfer of spent fuel from the wet storage pool to the ISFSI, as well as the eventual transfer of the spent fuel at the ISFSI to the DOE. Costs are included for the operation of the storage pool and the management of the ISFSI until such time that the transfer is complete. It does not include any spent fuel management expenses incurred prior to June 3, 2013, cost to construct the ISFSI, purchase the horizontal storage modules, nor does it include any costs related to the final disposal of the spent fuel.
"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.
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., Asset Retirement Obligation determinations). In reality, there can be considerable interaction between the activities in the three subcategories. For example, DEF 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 estimate is developed and costs are presented in 2013 dollars. As such, the estimate does not reflect the escalation of costs (due to inflationary and market forces) during the decommissioning project. The decommissioning periods and milestone dates for the analyzed SAFSTOR decommissioning scenario are identified in Table 1. The cost projected for license termination (in accordance with 10 CFR 50.75) is shown at the bottom of Table 2 along with the costs for spent fuel management and site restoration.

- 1. INTRODUCTION This report presents an estimate of the cost to decommission the Crystal River Unit 3 Nuclear Generating Plant (CR-3). The analysis relies upon site-specific, technical information from an earlier evaluation prepared in 2011,[11 updated to reflect current assumptions pertaining to the disposition of the nuclear unit and relevant industry experience in undertaking such projects. This estimate has been prepared for Duke Energy Florida, Inc. (DEF), formerly known as Florida Power Corporation, to comply with the requirements of 10 CFR 50.82(a)(4)(i).
The current estimate is designed to provide DEF with sufficient information to assess its 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.
1.1 OBJECTIVES OF STUDY The objectives of this study were to prepare a comprehensive estimate of the costs to decommission CR-3, to provide a sequence or schedule for the associated activities, and to develop waste stream projections from the decontamination and dismantling activities.
CR-3 has been safely shutdown since September 26, 2009, when the plant entered the Cycle 16 refueling outage to replace the steam generators. As of May 28, 2011, all fuel assemblies were removed from the reactor vessel and placed in the spent fuel pool for temporary storage. Certification of the permanent cessation of power operations and defueling was submitted to the NRC on February 20, 2013.[21 DEF has announced its intention to decommission under the SAFSTOR alternative.
1.2 SITE DESCRIPTION The CR-3 site is located in Citrus County, Florida, approximately 70 miles north of Tampa on the shore of the Gulf of Mexico. The generating site is comprised of four fossil-fired units and one nuclear unit. The Gulf of Mexico provides the heat sink for both Units 1 and 2 fossil-fired units, and the nuclear unit (natural draft towers provide the cooling for Units 4 and 5).
The nuclear steam supply system (NSSS) consists of a pressurized water reactor and a two-loop reactor coolant system, designed by Babcock & Wilcox.
TLG Services, Inc.
Crystal River Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific Decommissioning Cost Estimate Section 1, Page 2 of 9 The generating unit had a reference core design of 2609 MWt (thermal), with a corresponding net dependable capability electrical rating of 860 megawatts (electric) with the reactor at rated power.
The reactor coolant system is comprised of the reactor vessel and two heat transfer loops, each loop containing a vertical once-through type steam generator, and two single speed centrifugal reactor coolant pumps. In addition, the system includes an electrically heated pressurizer, a reactor coolant drain tank and interconnected piping. The system is housed within the reactor containment building or reactor building, a seismic Category I reinforced concrete structure. The reactor building is a reinforced concrete structure composed of a vertical cylinder with a shallow dome and flat circular foundation slab. The cylinder wall is prestressed with a post-tensioning system in the vertical and horizontal directions. The dome roof is prestressed utilizing a three-way post-tensioning system. The foundation slab is reinforced with conventional mild steel. The inside surface of the reactor building is lined with a carbon steel liner to ensure a high degree of leak tightness during operating and accident conditions.
Heat produced in the reactor was converted to electrical energy by the steam and power conversion system. A turbine -generator system converted the thermal energy of steam produced in the steam generators into mechanical shaft power and then into electrical energy. The unit's turbine generator consists of high-pressure and low-pressure turbine sections driving a direct-coupled generator at 1800 rpm. The turbines were operated in a closed feedwater cycle, which condensed the steam; the heated feedwater was returned to the steam generators. Heat rejected in the main condensers was removed by the circulating water system. The condenser circulating water was taken from and returned to the Gulf of Mexico through the intake and discharge canals, respectively.
1.3 REGULATORY GUIDANCE The NRC provided initial decommissioning requirements in its rule "General Requirements for Decommissioning Nuclear Facilities," issued in June 1988.[31 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,"[41 which provided additional guidance to the licensees of nuclear facilities on the TLG Services, Inc.
Crystal River Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific DecommissioningCost Estimate Section 1, Page 3 of 9 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.
The decommissioning rulemaking 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. With rulemaking permitting the controlled release of a site,[5] 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. 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.[6 ] However, the NRC's staff has recommended that rulemaking be deferred, based upon several factors, e.g., no licensee has committed to pursuing the entombment option, the unresolved issues associated with the disposition of greater-than-Class C material (GTCC), and the NRC's current priorities, at least until after the additional research studies are complete. The Commission concurred with the staffs recommendation.
In 1996, the NRC published revisions to the general requirements for decommissioning nuclear power plants.[71 When the decommissioning regulations were adopted in 1988, it was assumed that the majority of licensees would decommission at the end of the facility's operating licensed life.
Since that time, several licensees permanently and prematurely ceased TLG Services, Inc.
Crystal River Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific DecommissioningCost Estimate Section 1, Page 4 of 9 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 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"[8 ] (NWPA) in 1982, assigning the federal government's long-standing responsibility for disposal of the spent nuclear fuel created by the commercial nuclear generating plants to the DOE. The DOE was to begin accepting spent fuel and high-level waste by January 31, 1998; however, to date no progress in the removal of spent fuel from commercial generating sites has been made.
Today, the country is at an impasse on high-level waste disposal, even with the License Application for a geologic repository submitted by the DOE to the NRC in 2008. The current administration has cut the budget for the repository program while promising to "conduct a comprehensive review of policies for managing the back end of the nuclear fuel cycle ...
and make recommendations for a new plan."[a9 Towards this goal, the administration appointed a Blue Ribbon Commission on America's Nuclear Future (Blue Ribbon Commission) to make recommendations for a new plan for nuclear waste disposal. The Blue Ribbon Commission's charter includes a requirement that it consider "[o]ptions TLG Services, Inc.
Crystal River Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific Decommissioning Cost Estimate Section 1, Page 5 of 9 for safe storage of used nuclear fuel while final disposition pathways are selected and deployed."
On January 26, 2012, the Blue Ribbon Commission issued its "Report to the Secretary of Energy"1101 containing a number of recommendations on nuclear waste disposal. Two of the recommendations that may impact decommissioning planning are:
" "[T]he United States [should] establish a program that leads to the timely development of one or more consolidated storage facilities"
" "[Tjhe United States should undertake an integrated nuclear waste management program that leads to the timely development of one or more permanent deep geological facilities for the safe disposal of spent fuel and high-level nuclear waste."
In January 2013, the DOE issued the "Strategy for the Management and Disposal of Used Nuclear Fuel and High-Level Radioactive Waste," in response to the recommendations made by the Blue Ribbon Commission and as "a framework for moving toward a sustainable program to deploy an integrated system capable of transporting, storing, and disposing of used nuclear fuel..."W]
"With the appropriate authorizations from Congress, the Administration currently plans to implement a program over the next 10 years that:
" Sites, designs and licenses, constructs and begins operations of a pilot interim storage facility by 2021 with an initial focus on accepting used nuclear fuel from shut-down reactor sites;
" Advances toward the siting and licensing of a larger interim storage facility to be available by 2025 that will have sufficient capacity to provide flexibility in the waste management system and allows for acceptance of enough used nuclear fuel to reduce expected government liabilities; and
" Makes demonstrable progress on the siting and characterization of repository sites to facilitate the availability of a geologic repository by 2048."
In 2010, the government discontinued work on the review of the application to construct a geologic repository for spent nuclear fuel and high-level waste at Yucca Mountain. However, the US Court of Appeals for the District of Columbia Circuit recently issued a writ of mandamus TLG Services,Inc.
Crystal River Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific DecommissioningCost Estimate Section 1, Page 6 of 9 (in August 2013) ordering NRC to comply with federal law and restart its review of DOE's Yucca Mountain repository license application.
Even with a favorable review, there is considerable uncertainty as to DOE's future actions on the growing backlog of spent fuel, even with the additional direction provided by the Blue Ribbon Commission. For purposes of this analysis, Duke Energy evaluated the feasibility of several spent fuel disposition scenarios, both near (e.g., 2021) and long-term (e.g., 2048), as well as a more moderate scenario.
For purposes of this estimate, the spent fuel management plan for the CR-3 spent fuel is based in general upon: 1) a 2032 start date for DOE initiating transfer of commercial spent fuel to a federal facility, 2) priority pickup for shutdown reactors, and 3) pickup based on the permanent shutdown date of the plant (oldest fuel first). Assuming a maximum rate of transfer of 3,000 metric tons of uranium (MTU)/year, [121 and the aforementioned assumptions on spent fuel management, transfer of spent fuel from CR-3 to DOE would begin in 2035 and the spent fuel from CR-3 would be completely removed from the site by the end of 2036.
The NRC requires that licensees establish a program to manage and provide funding for the caretaking of all irradiated fuel at the reactor site until title of the fuel is transferred to the DOE. 1131 Interim storage of the fuel, until the DOE has completed the transfer, will be in the auxiliary building's storage pool, as well as at an Independent Spent Fuel Storage Facility (ISFSI) to be constructed on the site. Once the wet storage pool is emptied, the auxiliary building can be prepared for long-term storage.
DEF's position is that the DOE has a contractual obligation to accept the spent fuel 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.
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,[141 and its Amendments of 1985,[15] the states became ultimately responsible for the disposition of low-level radioactive waste generated within their own borders.
TLG Services, Inc.
CrystalRiver Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific DecommissioningCost Estimate Section 1, Page 7 of 9 With the exception of Texas, no new compact facilities have been successfully sited, licensed, and constructed. Construction of the Texas Compact disposal facility is now essentially complete and the facility was declared operational by the operator, Waste Control Specialists (WCS), in November 2011. The facility will be able to accept limited quantities of non-Compact waste; however, at this time the cost for non-Compact generators is being negotiated on an individual basis.
Disposition of the various waste streams produced by the decommissioning process considered all options and services currently available to DEF. The majority of the low-level radioactive waste designated for direct disposal (Class A[11]) can be sent to EnergySolutions' facility in Clive, Utah. Therefore, disposal costs for Class A waste were based upon DEF's Life of Plant Agreement with EnergySolutions. This facility is not licensed to receive higher activity waste (Class B and C).
The WCS facility is able to receive the Class B and C waste. As such, for this analysis, Class B and C waste is assumed to be shipped to the WCS facility and disposal costs for the waste were based upon preliminary and indicative information on the cost for such from WCS (and intermediary processors such as Studsvik).
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 study, components that must be disposed of as GTCC waste would be packaged in the same canisters used for spent fuel. Because dismantlement would occur after the projected date for DOE acceptance of spent fuel and high level waste, for purposes of this study it is assumed that the canisters would be shipped directly to a DOE facility.
TLG Services, Inc.
Crystal River Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific DecommissioningCost Estimate Section 1, Page 8 of 9 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 estimate reflects 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,"[171 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 estimate assumes that the CR-3 site will be remediated to the levels specified in 10 CFR 20.1402, "Radiological criteria for unrestricted use," although the remediation measures included in this estimate are believed to be sufficient to result in substantially lower levels than required by the foregoing regulation.
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).[1 8 1 An additional and separate limit of 4 millirem per year, as defined in 40 CFR §141.16, is applied to drinking water.1 191 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)[201 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.
CrystalRiver Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific DecommissioningCost Estimate Section 1, Page 9 of 9 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.
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. SAFSTOR DECOMMISSIONING ALTERNATIVE A detailed cost estimate was developed to decommission the CR-3 nuclear unit for the SAFSTOR decommissioning alternative. The following narrative describes the basic activities associated with the 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 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 estimate developed for CR-3 is also divided into phases or periods; however, demarcation of the periods is based upon major milestones within the project or significant changes in the projected expenditures.
2.1 PERIOD 1 - PREPARATIONS 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 pool 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.
Preparations for long-term storage include the revision of technical specifications appropriate to the operating conditions and requirements (i.e.,
permanently shutdown technical specifications), a characterization of the facility and major components, and the development of the PSDAR.
TLG Services,Inc.
Crystal River Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific Decommissioning Cost Estimate Section 2, Page 2 of 7 The process of placing the plant in safe-storage includes, but is not limited to, the following activities:
" Creation of an organizational structure to support the decommissioning plan and evolving emergency planning and site security requirements.
" Design and installation of an alternate spent fuel cooling system, including air-cooled heat exchangers to be located on the control complex roof and piped into the existing service water system.
" Isolation of the spent fuel pool and fuel handling systems so that safe-storage operations may commence on the balance of the plant.
" Construction of the ISFSI pad and acquisition of the dry fuel storage modules for off-load of the spent fuel pool.
" Removal of systems from service that are no longer required to support site operations or maintenance.
" Processing and disposal of water and filter and treatment media that is not required to support dormancy operations.
" Disposition of legacy waste, including the retired steam generators, reactor vessel closure head and hot leg piping.
" Reconfiguration of ventilation, fire protection, electric power, lighting, and other plant systems needed to support long-term storage and periodic plant surveillance and maintenance.
" Cleaning or fixing loose surface contamination to facilitate future building access and plant maintenance.
" Performing an interim radiation survey of plant, posting caution signs and establishing access requirements, where appropriate.
Posting and/or cordoning off high contamination / high radiation areas.
Reconfiguring security boundaries and surveillance systems, as required.
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, TLG Services, Inc.
CrystalRiver Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific DecommissioningCost Estimate Section 2, Page 3 of 7 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 monitor and control releases of radioactive material to the environment. 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 safe-guard the spent fuel while on site and prevent unauthorized entry. The security fence, sensors, alarms, and other surveillance equipment provide security. Fire and radiation alarms are also monitored and maintained.
Once the ISFSI has been constructed (estimated in late 2016), the spent fuel will be transferred from the spent fuel pool to horizontal storage modules located on the ISFSI pad. Spent fuel transfer is expected to be complete by January 2019. The pool will be drained and readied for long-term storage once the fuel transfer is completed. The spent fuel pool will be maintained in a recoverable condition until all fuel has been removed from the site unless contingency plans are put in place for offload of DSCs if needed.
For purposes of planning and this cost estimate, the transfer of the spent fuel from the ISFSI to a DOE facility is projected to begin in 2035 and be completed a year later (end of 2036), although transfer could occur earlier if DOE is successful in implementing its current strategy for the management and disposal of spent fuel.. The ISFSI will then be secured for long-term storage and decommissioned along with the power block structures in Period 4.
2.3 PERIOD 3 - PREPARATIONS FOR DECOMMISSIONING CR-3 is currently expected to remain in safe storage until 2067, at which time preparations for decommissioning would commence. The period of storage was based upon, and considered, the available financial resources, projected fund growth and the cost to complete decommissioning and plant dismantlement.
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 TLG Services, Inc.
CrystalRiver Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific Decommissioning Cost Estimate Section 2, Page 4 of 7 organization. Final planning for activities and the writing of activity specifications and detailed procedures are also initiated at this time.
At least two years prior to the anticipated date of license termination, 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 Commission.
2.4 PERIOD 4 - DECOMMISSIONING This period includes the physical decommissioning activities associated with the removal and disposal of contaminated and activated components and structures, including the successful termination of the 10 CFR §50 operating license. Although the initial radiation levels due to 6 0Co 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, 59Ni, and 63Ni. Portions of the biological shield will also be radioactive due to the presence of activated trace elements with long half-lives (l5 2 Eu and 15 4Eu).
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.
Significant decommissioning activities in this phase include:
Reconfiguration and modification of site structures and facilities, as needed to support decommissioning operations. This may include establishing a centralized processing area to facilitate equipment removal and component preparation for off-site disposal. Modifications may also be required to the reactor building to facilitate access of de-construction equipment, support the segmentation of the reactor vessel internals, and for large 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.
TLG Services, Inc.
Crystal River Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific Decommissioning Cost Estimate Section 2, Page 5 of 7
" Procurement (lease or purchase) of shipping canisters, cask liners, and industrial packages for the disposition of low-level radioactive waste.
" Decontamination of components and piping systems as required to control (minimize) worker exposure.
" Removal of piping and components no longer essential to support decommissioning operations.
" Removal of control rod drive housings and the head service structure from the reactor vessel head.
" Removal and segmentation of the plenum assembly. Segmentation will maximize the loading of the shielded transport casks, (i.e., by weight and activity). The operations will be conducted under water using remotely operated tooling and contamination controls.
" Disassembly and segmentation, if necessary, of the remaining reactor internals, including the core former and baffles and lower core support assembly. Depending on packaging, some material may exceed Class C disposal requirements. Any such material will be packaged in modified fuel storage canisters for transfer to DOE.
" Segmentation / removal of the reactor vessel. If segmented, a shielded platform will be installed for segmentation as cutting operations will be performed in-air using remotely operated equipment within a contamination control envelope. The water level will be maintained just below the cut to minimize the working area dose rates. Segments will be transferred in-air to containers that are stored under water, for example, in an isolated area of the refueling canal.
" Removal of the activated and contaminated 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 D-rings necessary for access and component extraction will be removed.
" Removal of the steam generators for processing and pressurizer for controlled disposal. The generators will be moved to an on-site processing center and prepared for transport to the waste processor. To facilitate transport, the generators will be cut in half, across the tube bundle. The exposed ends will be capped and sealed. The pressurizer will be disposed of intact.
" 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).
TLG Services, Inc.
Crystal River Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific Decommissioning Cost Estimate Section 2, Page 6 of 7 Removal of the steel liners from refueling canal, disposing of the activated and contaminated sections as radioactive waste. Removal of any activated/contaminated concrete.
- Surveys of the decontaminated areas of the reactor building.
- Remediation and removal of the contaminated equipment and material from the auxiliary building and any other contaminated area. 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 areas. 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 will be released for unrestricted disposition, e.g., as scrap, recycle, or general disposal. Contaminated material will be 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.
- Remediation of the west settling pond (approximately 500 cubic yards), and the excavation and removal of the station drain tank line, as well as the underground portions of the nitrogen line.
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)."[21] 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 release of the property for unrestricted use and license termination.
The NRC will terminate the operating license if it determines that site remediation has been performed in accordance with the LTP, and that the TLG Services, Inc.
Crystal River Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific Decommissioning Cost Estimate Section 2, Page 7 of 7 terminal radiation survey and associated documentation demonstrate that the facility is suitable for release.
2.5 PERIOD 5 - 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 can substantially damage power block structures, potentially weakening the footings and structural supports. It is unreasonable to anticipate that these structures would be repaired and preserved after the radiological contamination is removed. Dismantling site structures with a work force already mobilized is more efficient and less costly than if the process is deferred. Consequently, this study assumes that site structures addressed by this analysis are removed to a nominal depth of three feet below the top grade of the embankment, wherever possible.
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.

- 3. COST ESTIMATE The cost estimate prepared for decommissioning CR-3 considers the unique features of the site, including the NSSS, power generation systems, support services, site buildings, and ancillary facilities. The basis of the estimate, 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 estimate was developed using the site-specific, technical information from the 2011 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 estimate follows the basic approach originally presented in the AIF/NESP-036 study report, "Guidelines for Producing Commercial Nuclear Power Plant Decommissioning Cost Estimates," [22] and the DOE "Decommissioning Handbook."[23] 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.[241 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.
TLG Services, Inc.
Crystal River Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific DecommissioningCost Estimate Section 3, Page 2 of 24 This analysis reflects lessons learned from TLG's involvement in the Shippingport Station Decommissioning Project, completed in 1989, as well as 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, 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%
- Respiratory Protection Factor 0% to 50%
- Radiation/ALARA Factor 0% to 15%
- Protective Clothing Factor 0% to 30%
- 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.
Crystal River Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific DecommissioningCost Estimate Section 3, Page 3 of 24 engineering, equipment rental, and support services such as quality control and security. This systematic approach for assembling decommissioning estimates ensures a high degree of confidence in the reliability of the resulting costs.
3.3 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.
3.3.1 Contingency 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.
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"[25] 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 maximum efficiency; therefore, consistent with industry practice, contingency is included. 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 TLG Services, Inc.
Crystal River Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific Decommissioning Cost Estimate Section 3, Page 4 of 24 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:
" Decontamination 50%
- Contaminated Component Removal 25%
" Contaminated Component Packaging 10%
" Contaminated Component Transport 15%
- Low-Level Radioactive Waste Disposal 25%
- Low-Level Radioactive Waste Processing 15%
- Reactor Segmentation 75%
- NSSS Component Removal 25%
- Reactor Waste Packaging 25%
- Reactor Waste Transport 25%
" Reactor Vessel Component Disposal 50%
- GTCC Disposal 15%
" Non-Radioactive Component Removal 15%
" Heavy Equipment and Tooling 15%
- Construction 15%
- Supplies 25%
- Engineering 15%
" Energy 15%
- Characterization and Termination Surveys 30%
- Spent Fuel Transfer 15%
- ISFSI Decommissioning 25%
" Operations and Maintenance 15%
- Taxes and Fees 10%
" Insurance 10%
- Staffing (plant, contractor and security) 15%
The contingency values are applied to the appropriate components of the estimate on a line item basis, except where actual budgets were provided or estimates for activities provided by DEF assume to include contingency.
TLG Services, Inc.
Crystal River Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific Decommissioning Cost Estimate Section 3, Page 5 of 24 3.3.2 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:
" 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.
" Pricing changes for basic inputs such as labor, energy, materials, and disposal. 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 should be revisited periodically and addressed through revisions or updates of the base estimate.
TLG Services, Inc.
Crystal River Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific DecommissioningCost Estimate Section 3, Page 6 of 24 3.4 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.
3.4.1 Spent Fuel Management The cost to dispose the spent fuel generated from plant operations is not reflected within the estimate to decommission CR-3. 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/kW-hr 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 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 estimate, 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 an internal DEF probability assessment and the most recent information from the DOE on likely future actions regarding interim and long-term solutions to spent fuel disposition.
For purposes of this estimate, the spent fuel management plan for the CR-3 spent fuel is based in general upon: 1) a 2032 start date for DOE initiating transfer of commercial spent fuel to a federal facility, 2) priority pickup for shutdown reactors, and 3) pickup based on the permanent shutdown date of the plant (oldest fuel first). Assuming a maximum rate of transfer of 3,000 metric tons of uranium (MTU)/year,[26] and the aforementioned assumptions on spent fuel management, the spent fuel from CR-3 would be completely removed from the site by the end of 2036.
ISFSI An ISFSI will be constructed adjacent to the power block and used to off-load the spent fuel pool. The ISFSI is assumed to be available by the end of 2016 with the majority of spent fuel transferred to the facility in 2017 TLG Services, Inc.
CrystalRiver Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific Decommissioning Cost Estimate Section 3, Page 7 of 24 and 2018. The estimate includes the costs to purchase, load, and transfer the dry shielded canisters (DSCs), as well as operations and maintenance costs (e.g., staffing, security, insurance, and licensing fees, etc.). It does not include the cost to construct the ISFSI and purchase the horizontal storage modules (HSMs).
Assuming that DOE begin accepting spent fuel in 2032 (from shutdown units), CR-3 fuel is projected to be first removed from the site in 2035.
The process is expected to be completed by the end of the following year.
Once emptied, the ISFSI will be secured for storage. Decommissioning of the ISFSI will be deferred and synchronized with the power block structures.
Storage Canister Design DOE has not identified any cask systems it may use. As such, for the purpose of this analysis, the design and capacity of the ISFSI is based upon the NUHOMS system, with a 32 fuel assembly internal DSC and a concrete HSM.
Canister Loading and Transfer The cost for the labor and equipment to seal each spent fuel canister once it is loaded and to load/transport the spent fuel from the pool to the ISFSI pad was provided by DEF based upon current vendor-supplied information. For estimating purposes, an allowance was used for the transfer of the fuel from the ISFSI into a DOE transport cask.
Operations and Maintenance The estimate includes the cost for operation and maintenance of the spent fuel pool and the ISFSI. Pool operations are expected to continue through January of 2019, as which time it will be emptied and secured for storage. ISFSI operations are expected to continue through December 2036, based upon the previously outlined assumptions on DOE performance.
ISFSI Decommissioning In accordance with 10 CFR §72.30, licensees must have a proposed decommissioning plan for the ISFSI site and facilities that includes a cost estimate to implement. The plan should contain sufficient information on the proposed practices and procedures for the TLG Services, Inc.
CrystalRiver Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific Decommissioning Cost Estimate Section 3, Page 8 of 24 decontamination of the ISFSI and for the disposal of residual radioactive materials after all spent fuel, high-level radioactive waste, and reactor-related GTCC waste have been removed.
A multi-purpose (storage and transport) dry shielded storage canister with a horizontal, reinforced concrete storage module is used as a basis for the cost analysis. As an allowance for module remediation, 6 modules are assumed to have some level of neutron-induced activation after approximately 20 years of storage (i.e., to levels exceeding free-release limits), equivalent to the number of modules required to accommodate the final core off load. The steel support structure is assumed to be removed from these modules and sent, along with the concrete, for controlled disposal. The cost of the disposition of this material, as well as the demolition of the ISFSI facility, is included in the estimate.
The cost estimate for decommissioning the ISFSI reflects: 1) the cost of an independent contractor performing the decommissioning activities; 2) an adequate contingency factor; and 3) the cost of meeting the criteria for unrestricted use. The cost summary for decommissioning the ISFSI is presented in Appendix D.
GTCC The dismantling of the reactor internals generates 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. 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 in the same canisters used to store spent fuel and disposed of as high-level waste, at a cost equivalent to that envisioned for the spent fuel.
The GTCC material is assumed to be shipped directly to a DOE facility as it is generated from the segmentation of the reactor vessel internals.

Crystal River Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific Decommissioning Cost Estimate Section 3, Page 9 of 24 3.4.2 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 currently being decommissioned.
Access to navigable waterways has allowed these large packages to be transported to the Barnwell disposal site with minimal overland travel.
Intact disposal of the reactor vessel and internal components can provide 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, 0 there were no man-made or natural terrain features between the plant site and the disposal location that could produce a large drop, and 0 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 and site proved favorable in demonstrating compliance with land disposal regulations.
It is not known whether this option will be available to CR-3. 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, the study assumes the reactor vessel will TLG Services, Inc.

With lower levels of activation, the vessel shell can be packaged more efficiently than the curie-limited internal components. This will allow the use of more conventional waste packages rather than shielded casks for transport.
3.4.3 Primary System Components Due to the natural decay of radionuclides over the dormancy period, a chemical decontamination of the primary coolant system 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 reactor building and placed onto a multi-wheeled vehicle for transport to an on-site processing and storage area.
The generators are segmented on-site to facilitate transportation. Each unit is cut in half, across the tube bundle. The exposed ends are capped and sealed. Each component is then loaded onto a rail car for transport to the waste processing facility.
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.

Crystal River Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific DecommissioningCost Estimate Section 3, Page 11 of 24 3.4.4 Retired Components The estimate includes the cost to dispose of the retired steam generators, reactor closure head and hot leg piping. Disposition is currently scheduled to occur in 2014 and 2015, prior to the plant entering dormancy.
3.4.5 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.
3.4.6 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.[271 The contaminated material will be packaged in Industrial Packages (IP-1, IP-2, or IP-3, as defined in subpart 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 accordance with 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., 13 7Cs, 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 TLG Services, Inc.
Crystal River Unit 3 Nuclear GeneratingPlant Document No. P23-1680-00.1, Rev. 0 Site-Specific Decommissioning Cost Estimate Section 3, Page 12 of 24 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, rail, and/or multi-wheeled transporter.
Transportation costs for material requiring controlled disposal are based upon the mileage to the EnergySolutions facility in Clive, Utah and the Waste Control Specialist facility in Andrews County, Texas.
Transportation costs for off-site waste processing are based upon the mileage to Memphis, Tennessee. Truck transport costs are estimated using published tariffs from Tri-State Motor Transit.[281 The transportation cost for the GTCC material is assumed to be included in the disposal cost.
3.4.7 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 Appendix C, 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.

Crystal River Unit 3 Nuclear-GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific Decommissioning Cost Estimate Section 3, Page 13 of 24 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.
Disposal fees are based upon estimated charges, with higher rates applying 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 the current cost for disposal at E nergySolut tons facility in Clive, Utah. Disposal costs for the higher activity waste (Class B and Q are based upon preliminary and indicative information on the cost for such from WCS.
The estimate includes a Florida Department of Health inspection fee; applied to the volume of low-level radioactive waste shipped to commercial low-level radioactive waste management facilities for treatment, storage, or disposal (Florida Radiation Protection Act, s.
404.131(3)(a)).
Material exceeding Class C limits (limited to material closest to the reactor core and comprising less than 1% of the total waste volume) is generally not suitable for shallow-land disposal. This material is packaged in the same multi-purpose canisters used for spent fuel transport.
3.4.8 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. Local building codes and state 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 the top grade of the embankment (i.e., 118'-6"), wherever possible.
The embankment and the foundations of buildings located on the embankment, below this elevation, will be abandoned in place. Below grade voids will be filled with clean concrete rubble (processed to TLG Services, Inc.
Crystal River Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific Decommissioning Cost Estimate Section 3, Page 14 of 24 removed rebar), generated from demolition activities. Excess construction debris is trucked off site as an alternative to onsite disposal. Certain facilities, which have continued use or value (e.g., the switchyard) are left intact.
The intake and discharge canals are abandoned. No remediation is anticipated.
Costs are included for the remediation of minor quantities of asbestos containing materials (e.g., gaskets, insulation, construction materials) and for the remediation of the firing range (i.e., removal of soil containing lead residue).
3.5 ASSUMPTIONS The following are the major assumptions made in the development of the estimate for decommissioning the site.
3.5.1 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.
3.5.2 Labor Costs DEF, as the licensee, will continue to provide site operations support, including decommissioning program management, licensing, radiological protection, and site security. A Decommissioning Operations Contractor (DOC) will provide the supervisory staff needed to oversee the labor subcontractors, consultants, and specialty contractors needed to perform the work required for the decontamination and dismantling effort. The DOC will also provide the engineering services needed to develop activity specifications, detailed procedures, detailed activation analyses, and support field activities such as structural modifications.
TLG Services, Inc.
Crystal River Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific Decommissioning Cost Estimate Section 3, Page 15 of 24 Site personnel costs are based upon average salary information provided by DEF. Overhead costs are included for site and corporate support, reduced commensurate with the staffing of the project.
The craft labor required to decontaminate and dismantle the nuclear unit is acquired through standard site contracting practices. The current cost of labor at the site is used as an estimating basis.
Security, while reduced from operating levels, is maintained throughout the decommissioning for access control, material control, and to safeguard the spent fuel. Once the spent fuel is removed from the site, the organization is converted from a "nuclear" to an industrial security force.
3.5.3 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., 137Cs, 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.[291 Actual estimates are derived from the curie/gram values contained therein and adjusted for the different mass of the CR-3 components, operating life, and period of decay. Additional short-lived isotopes were derived from NUREG/CR-0130[301 and NUREG/CR-0672,[31] 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. The estimate does include an allowance for the legacy waste currently stored in the spent fuel pool. The $3 million dollars allocated for its disposal is expected to be spent in 2014.
Neutron activation of the containment building structure is assumed to be confined to the biological shield.
TLG Services, Inc.
Crystal River Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific Decommissioning Cost Estimate Section 3, Page 16 of 24 3.5.4 General Transition Activities Existing warehouses are cleared of non-essential material and remain for use by DEF 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.
" Process operating waste inventories, i.e., the estimate does not address the disposition of any legacy wastes; 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. DEF will make economically reasonable efforts to salvage equipment. 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 estimate 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 TLG Services, Inc.
Crystal River Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific Decommissioning Cost Estimate Section 3, Page 17 of 24 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.
Equipment and materials acquired for the power uprate, and not installed, are assumed to be dispositioned at no net cost or credit to the project.
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) during decommissioning are included and based upon operating premiums. Reductions in premiums, upon entering dormancy and beyond, are based upon the guidance provided in SECY-00-0145, "Integrated Rulemaking Plan for Nuclear Power Plant Decommissioning." 1 321 The NRC's financial protection requirements are based on various reactor (and spent fuel) configurations.
Taxes The estimate includes an allowance for property taxes (or payments in lieu of taxes).
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.

SUMMARY
Schedules of expenditures are provided in Tables 3.1 through 3.4. The tables delineate the cost contributors by year of expenditures as well as cost contributor (e.g., labor, materials, and waste disposal).
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 §50.75). In situations where the long-term management of spent fuel is not an issue, the cost reported for this subcategory is generally sufficient to terminate the unit's operating license.
The "Spent Fuel Management" subcategory contains costs associated with the containerization and transfer of spent fuel from the wet storage pool to the ISFSI, as well as the eventual transfer of the spent fuel at the ISFSI to the DOE. Costs are included for the operation of the storage pool and the management of the ISFSI until such time that the transfer is complete. It does not include any spent fuel management expenses incurred prior to June 3, 2013, cost to construct the ISFSI, purchase the horizontal storage modules, nor does it include any costs related to the final disposal of the spent fuel.
"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.
As noted within this document, the estimate is developed and costs are presented in 2013 dollars. As such, the estimate does not reflect the escalation of costs (due to inflationary and market forces) during the decommissioning project. Schedules of expenditures are based upon the detailed activity costs reported in Appendix C, along with the schedule presented in Section 4.

- 4. SCHEDULE ESTIMATE The schedule for the decommissioning scenario considered in this study follows 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 3.4.1.
The start and end dates of the decommissioning subperiods are shown in Table 4.1. A schedule or sequence of activities for the deferred decommissioning portion of the SAFSTOR alternative is presented in Figure 4.1. The scheduling sequence assumes that fuel has been removed from the site prior to the start of decontamination and dismantling activities. 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 33 prepared using the "Microsoft Project Professional 2010" computer software.[ 1 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 person-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 spent fuel handling area in the auxiliary building is isolated until such time that all spent fuel has been discharged from the spent fuel pool to the ISFSI.
" 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.

Crystal River-Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific Decommissioning Cost Estimate Section 4, Page 2 of 5 For plant systems removal, the systems with the longest removal durations in areas on the critical path are considered to determine the duration of the activity.
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.
The project timeline is provided in Figure 4.2 with milestone dates based on the 2013 declaration of permanent cessations of operations. The fuel pool is emptied by January 2019, while ISFSI operations continue until the DOE can complete the transfer of assemblies to its repository. Deferred decommissioning is assumed to commence in 2067 with the operating license is terminated within a 60-year period from the declared 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,[3 4] 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
§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 destinations for the various waste streams from decommissioning are identified in Figure 5.1. The volumes are shown on a line-item basis in Appendix C and summarized in Table 5.1. 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 casks.
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).
13 7 While the dose rates decrease with time, radionuclides such as Cs will still control the disposition requirements.

COystal River Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific DecommissioningCost Estimate Section 5, Page 2 of 4 The waste material produced in the decontamination and dismantling of the nuclear plant is primarily generated during Period 4 of SAFSTOR. Material that is considered potentially contaminated when removed from the radiological controlled area (e.g., concrete and dry active waste) and metal with low levels of contamination are sent to processing facilities in Tennessee for conditioning and disposal. The disposal volumes reported in the tables reflect the savings resulting from reprocessing and recycling. Heavily contaminated components and activated materials are routed for direct, controlled disposal.
Disposal costs for Class A waste were based upon DEF's Life of Plant Agreement with EnergySolutions. Separate rates were used for containerized waste and large components, including the pressurizer and reactor coolant pumps. Demolition debris including miscellaneous steel, scaffolding, and concrete was disposed of at a bulk rate. The decommissioning waste stream also includes 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 preliminary and indicative information on the cost for such waste from WCS.
The estimate includes a Florida Department of Health inspection fee; applied to the volume of low-level radioactive waste shipped to commercial low-level radioactive waste management facilities for treatment, storage, or disposal (Florida Radiation Protection Act, s. 404.131(3)(a)).
A small quantity of material will be generated during the decommissioning will not be considered suitable for near-surface disposal, and is assumed to be disposed of in a geologic repository, in a manner similar to that envisioned for spent fuel disposal.
This material, known as GTCC material, is estimated to require five spent fuel storage canisters (or the equivalent) to dispose of the most radioactive portions of the reactor vessel internals. The volume and weight reported in Table 5.1 represents the packaged weight and volume of the spent fuel storage canisters.

Crystal River Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific Decommissioning Cost Estimate Section 6, Page I of 5 6.RESULTS The analysis to estimate the cost to decommission CR-3 relied upon the site-specific, technical information developed for a previous analysis prepared in 2011. While not an engineering study, the estimate provides DEF with sufficient information to assess their financial obligations, as they pertain to the decommissioning of the nuclear station.
The estimate described in this report is based on numerous fundamental assumptions, including 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 pool until the spent fuel can be off-loaded to the ISFSI. The ISFSI will be used to safeguard the spent fuel until such time that the DOE can complete the transfer of the assemblies to its facility.
The cost projected for deferred decommissioning (SAFSTOR) is estimated to be
$1,180.1 million. The majority of this cost (approximately 73.0%) is associated with placing the unit in storage, ongoing caretaking of the unit during dormancy, and the eventual physical decontamination and dismantling of the nuclear unit so that the operating license can be terminated. Another 22.5% is associated with the management, interim storage, and eventual transfer of the spent fuel. The remaining 4.5% is for the demolition of the designated structures and limited restoration of the site. The costs are allocated, by subperiod, into the categories of License Termination, Spent Fuel Management and Site Restoration in Table 6. 1.
The primary cost contributors, identified in Table 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 DEF will oversee the decommissioning program, using a DOC to manage the decommissioning labor force and the associated subcontractors. The size and composition of the management organization varies with the decommissioning phase and associated site activities. However, once the operating license is terminated, the staff is substantially reduced for the conventional demolition and restoration of the site.
As described in this report, the spent fuel pool will be isolated and an independent spent fuel island created. Once the ISFSI is constructed, the spent fuel will be packaged into transportable steel canisters for interim storage. Dry storage of the fuel provides additional flexibility in the event the DOE is not able to meet the TLG Services, Inc.
Crystal River Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific DecommissioningCost Estimate Section 6, Page 2 of 5 current timetable for completing the transfer of assemblies to an off-site facility and minimizes the associated caretaking expenses.
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, the EnergySolutions facility in Utah is the assumed destination for the majority of the low-level radioactive material required controlled disposal, with the remaining high-activity waste destined for Waste Control Specialists' facility in Texas.
Components, requiring additional isolation from the environment (i.e., GTCC), are packaged for geologic disposal. The cost of geologic disposal is based upon a cost equivalent to 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. The methods employed in decontamination and dismantling are generally destructive and indiscriminate in inflicting collateral damage. 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.
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 minimiz e 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 TLG Services, Inc.
Crystal River Unit 3 Nuclear GeneratingPlant Document No. P23-1680-001, Rev. 0 Site-Specific Decommissioning Cost Estimate Section 6, Page 3 of 5 more economical means of handling the large volumes of material produced in the dismantling of a nuclear unit.
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 have been 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.
