SUMMARY
Florida Power Corporation, doing business as Progress Energy Florida, Inc.(Progress Energy), a subsidiary of Progress Energy, Inc., is seeking renewal of the operating license for the Crystal River Unit 3 Nuclear Generating Plant (Crystal River), currently set to expire at midnight on December 3, 2016. An application for the renewal of Facility Operating License No. DPR-72, for an additional 20-year period, was submitted to the Nuclear Regulatory Commission (NRC) on December 16, 2008. The application is currently under review.However, pursuant to 10 CFR 50.75(f)(3), each power reactor licensee shall at or about 5 years prior to the projected end of operations submit a preliminary decommissioning cost estimate which includes an up-to-date assessment of the major factors that could affect the cost to decommission.
This report presents an estimate of the cost to decommission the Crystal River assuming a cessation of operations after a nominal 40-year operating life in 2016. The cost estimate includes an assessment of the major factors that could affect the cost to decommission the Crystal River nuclear unit.Progress Energy is submitting this estimate to comply with the requirements of 10 CFR 50.75(f)(3).
Progress Energy has not determined or committed to a specific decommissioning approach for Crystal River at this time. However, it is Progress Energy's current plan for purposes of demonstrating the adequacy of funding to meet regulatory requirements to use the SAFSTOR decommissioning option based on the current license expiration date. License renewal is likely to require a need to revise this preliminary plan.The currently projected total cost to decommission the nuclear unit, assuming the SAFSTOR alternative, is estimated at $1,077.6 million, as reported in 2011 dollars.The cost includes the monies anticipated to be spent for operating license termination, spent fuel storage and site remediation 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.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 Nuclear Regulatory Commission (NRC or Commission) provided initial decommissioning requirements in its rule adopted on TLG Services, Inc.
Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Page vii of xxii June 27, 1988.111 In this rule, the NRC set forth financial criteria for decommissioning licensed nuclear power facilities.
The regulations addressed planning needs, timing, funding methods, and environmental review requirements for decommissioning.
The rule also defined three decommissioning alternatives as being acceptable to the NRC: DECON, SAFSTOR, and ENTOMB.DECON is defined as "the alternative in which the equipment, structures, and portions of a facility and site containing radioactive contaminants are removed or decontaminated to a level that permits the property to be released for unrestricted use shortly after cessation of operations."[
2 1 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."[3 1 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."[
4 1 As with the SAFSTOR alternative, decommissioning is currently required to be completed within 60 years.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.[51 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.

Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Page viii of xxii and content of the estimate is also consistent with the recommendations of Regulatory Guide 1.202, issued in February 2005.[J]Bases of the Cost Estimate For the purpose of the analysis, Crystal River was assumed to cease operations in December 2016, after 40 years of operations.
The unit would then be placed into safe-storage (SAFSTOR), with the spent fuel relocated to an Independent Spent Fuel Storage Installation (ISFSI) to await transfer to a Department of Energy (DOE)facility.
Based upon a 2020 start date for the pickup of spent fuel from the commercial nuclear power generators, Progress Energy anticipates that the removal of spent fuel from the site could be completed by the year 2057. For purposes of this analysis, the plant remains in safe-storage until 2071, 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.The analysis relies upon site-specific, technical information from an evaluation prepared in 2008,[7] updated to reflect current assumptions pertaining to the disposition of the nuclear unit and relevant industry experience in undertaking such projects.
The economic basis was reviewed for the current analysis and updated to reflect current site costs and budgets. The site-specific considerations and assumptions used in the previous evaluation were also revisited.
Modifications were incorporated where new information was available.
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 independent spent fuel storage installation (ISFSI)until such time that it can be transferred to the U.S. Department of Energy (DOE).Consequently, the estimate includes those costs to manage and subsequently decommission these 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 estimate incorporates a minimum cooling period for the spent fuel that resides in the storage pool when operations cease. Any residual fuel 6 "Standard Format and Content of Decommissioning Cost Estimates for Nuclear Power Reactors," Regulatory Guide 1.202, U.S. Nuclear Regulatory Commission, February 2005 7 "Decommissioning Cost Analysis for the Crystal River Plant, Unit 3," Document No. P23-1597-002, Rev. 0, TLG Services, Inc., October 2008 TLG Services, Inc.
Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Page ix of xxii remaining in the pool after the cooling period is relocated to the ISFSI to await transfer to a DOE facility.
The estimate also includes the dismantling of site structures and non-essential facilities and the limited restoration of the site.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,"[
8] and the DOE "Decommissioning Handbook."[
9] 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 material costs for the conventional disposition of components and structures relied upon information available in the industry publication, "Building Construction Cost Data," published by R.S. Means.[101 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.8 T.S.

Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Page x of xxii 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."["]
1 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 remaining operating life of the station.Contingency funds are expected to be fully expended throughout the program. As such, inclusion of contingency is necessary to provide assurance that sufficient funding will be available to accomplish the intended tasks.Low-Level Radioactive Waste Disposal The contaminated and activated material generated in the decontamination and dismantling of a commercial nuclear reactor is classified as low-level (radioactive) waste, although not all of the material is suitable for "shallow-land" disposal.
With the passage of the "Low-Level Radioactive Waste Policy Act" in 1980,[121 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.
The disposal facility in Barnwell, South Carolina is currently closed to generators outside the Atlantic Compact (comprising the states of Connecticut, New Jersey and South Carolina).
The commercial disposal facility on the Hanford Nuclear Reservation near Richland, Washington accepts low-level radioactive waste from the Northwest (Alaska, Hawaii, Idaho, Montana, Oregon, Utah, Washington and Wyoming) and Rocky Mountain (Colorado, Nevada, and New Mexico) Compact states. This leaves EnergySolutions' disposal facility in Clive, Utah as the only available option for the disposal of the majority of the low-level radioactive waste generated in 11 Project and Cost Engineers' Handbook, Second Edition, American Association of Cost Engineers, Marcel Dekker, Inc., New York, New York, p. 239.12 "Low-Level Radioactive Waste Policy Act of 1980," Public Law 96-573, 1980.13 "Low-Level Radioactive Waste Policy Amendments Act of 1985," Public Law 99-240, 1986.TLG Services, Inc.
Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Page xi of xxii decommissioning Crystal River (the Texas facility has limited the importation of waste from outside the Texas Compact).For the purpose of this analysis, Progress Energy's "Life of Plant Agreement" with EnergySolutions is used as the basis for estimating the disposal cost for the majority of the radioactive waste (Class A [141). EnergySolutions does not have a license to dispose of the more highly radioactive waste (Classes B and C), for example, generated in the dismantling of the reactor vessel.The Texas Commission on Environmental Quality (TCEQ), the environmental agency for the state, is responsible for the licensing of a low-level radioactive waste disposal facility for the Texas Compact. The agency granted Waste Control Specialists (WCS) a disposal license in 2009 and approval to commence construction in early 2011.Construction of the disposal facility is now essentially complete and the facility was declared operational in November 2011. However, to date, the TCEQ has only published interim disposal rates for the facility, in advance of the formal disposal rate-setting process, and only for Compact generators.
As a proxy, disposition of the Class B and C waste is based upon the last published rate schedule for non-compact waste for the Barnwell facility.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 (Greater-than-Class C or 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, GTCC is packaged in the same canisters used for spent fuel. The GTCC material is shipped directly to a DOE facility as it is generated.
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 14 U.S. Code of Federal Regulations, Title 10, Part 61, "Licensing Requirements for Land Disposal of Radioactive Waste" TLG Services, Inc.
Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Page xii of xxii decontamination to eliminate the portion of waste that does not require disposal as radioactive waste, compaction, incineration or metal melt. The estimate for Crystal River reflects the savings from waste recovery/volume reduction.
High-Level Radioactive Waste Management Congress passed the "Nuclear Waste Policy Act"[1 5 1 (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 NWPA provided that DOE would enter into contracts with utilities in which DOE would promise to take the utilities' spent fuel and high-level radioactive waste and utilities would pay the cost of the disposition services for that material.
NWPA, along with the individual contracts with the utilities, specified that the DOE was to begin accepting spent fuel by January 31, 1998.Since the original legislation, the DOE has announced several delays in the program schedule.
By January 1998, the DOE had failed to accept any spent fuel or high level waste, as required by the NWPA and utility contracts.
Delays continue and, as a result, generators have initiated legal action against the DOE in an attempt to obtain compensation for DOE's breach of contract.Completion of the decommissioning process is dependent upon the DOE's ability to remove spent fuel from the site in a timely manner. DOE's repository program assumes that spent fuel allocations will be accepted for disposal from the nation's commercial nuclear plants, with limited exceptions, in the order (the "queue") in which it was discharged from the reactor. Progress Energy's current spent fuel management plan for the Crystal River spent fuel is based in general upon: 1) a 2020 start date for DOE initiating transfer of commercial spent fuel to a federal facility and 2)expectations for spent fuel receipt by the DOE for the Crystal River fuel. Fuel could be completely removed from the site as early as 2057, based on an oldest fuel first priority, and the DOE achieving an annual rate of transfer (3,000 metric tons of uranium year) as reflected in DOE's latest Acceptance Priority Ranking and Annual Capacity Report dated June 2004 (DOE/RW-0567).
The assumed 2020 DOE start date is nominally based on the last position stated by the DOE. On July 15, 2008, the then-Director of the DOE's Office of Civilian Radioactive Waste Management testified before Congress that DOE "could be ready to begin accepting spent nuclear fuel by 2020," but his statement was based on continued program funding.[1 6] The current administration has cut the budget for the geological 15 "Nuclear Waste Policy Act of 1982 and Amendments," DOE's Office of Civilian Radioactive Management, 1982 16 Statement of Edward F. Sproat, III, Director Office of Civilian Radioactive Waste Management, U.S. Department of Energy, Before the Subcommittee on Energy and Air Quality Committee on TLG Services, Inc.
Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Page xiii of xxii repository program, but the administration has also appointed a Blue Ribbon Commission on America's Nuclear Future to make recommendations for a new plan for nuclear waste disposal.
That Commission's charter includes a requirement that the Commission consider "options for safe storage of used nuclear fuel while final disposition pathways are selected and deployed." Progress Energy believes that one or more monitored retrievable storage facilities could be put into place following a Blue Ribbon Commission recommendation for the same, within a relatively short time frame, at least by 2020. For example, a facility such as that licensed by the NRC to Private Fuel Storage could be used by the DOE to store fuel until a final disposition is determined.
It is generally necessary that spent fuel be cooled and stored for a minimum period at the generating site prior to transfer.
As such, the NRC requires that licensees establish a program to manage and provide funding for the management of all irradiated fuel at the reactor site until title of the fuel is transferred to the Secretary of Energy, pursuant to 10 CFR Part 50.54(bb).[1 7 1 This requirement is prepared for through inclusion of certain cost elements in the decommissioning estimate, for example, associated with the isolation and continued operation of the spent fuel pool and the ISFSI.The spent fuel pool is expected to contain freshly discharged assemblies (from the most recent refueling cycles) as well as the final reactor core at shutdown.
Over the following six and one half years the assemblies are packaged into multipurpose canisters for transfer to the DOE or to the ISFSI for interim storage. It is assumed that this period provides the necessary cooling for the final core to meet the transport and/or storage requirements for decay heat.An ISFSI, operated under a Part 50 General License (in accordance with 10 CFR 72, Subpart K[18]), is in the process of being constructed to support continued plant operations.
The facility is assumed to be available to support future decommissioning operations.
Once the wet storage pool is emptied, the auxiliary building can be prepared for long-term storage.Progress Energy's position is that the DOE has a contractual obligation to accept Crystal River's 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. However, at this time, including the cost of storing spent fuel in this study is the most reasonable approach because it insures the availability of Energy and Commerce U.S. House of Representatives, July 15, 2008.17 U.S. Code of Federal Regulations, Title 10, Part 50, "Domestic Licensing of Production and Utilization Facilities," Subpart 54 (bb), "Conditions of Licenses." 18 U.S. Code of Federal Regulations, Title 10, Part 72, Subpart K, "General License for Storage of Spent Fuel at Power Reactor Sites."

Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Page xiv of xxii sufficient decommissioning funds at the end of the station's life if, contrary to its contractual obligation, the DOE has not performed earlier.Site Restoration Prompt dismantling of site structures (once the facilities are decontaminated) is clearly the most appropriate and cost-effective option. It is unreasonable to anticipate that these structures would be repaired and preserved after the radiological contamination is removed. The cost to dismantle site structures with a work force already mobilized on site is more efficient than if the process is deferred.Site facilities quickly degrade without maintenance, adding additional expense and creating potential hazards to the public and the demolition work force.Consequently, this study assumes that site structures are removed to a nominal depth of three feet below the local grade level wherever possible.
The site is then to be graded and stabilized.
Decommissioning Trust Funds As of September 30, 2011, the aggregate trust fund balance for Crystal River was approximately
$578.0 million. The total includes Progress Energy Florida's share (91.8%), as well as that of the nine minority owners.[1 9]Financial Assurance Progress Energy intends to fund the expenditures for license termination (comprising approximately 70% of the total cost) from the decommissioning trust fund currently held by Progress Energy as well as the nine minority owners. The management of the spent fuel, until it can be transferred to the DOE, may be funded from excess trust fund earnings and from proceeds from spent fuel litigation against the Department of Energy (DOE). Expenditures from the trust fund for the management of the spent fuel will not reduce the value of the decommissioning trust fund to below the amount necessary to place and maintain the reactor in safe storage. The licensee would make the appropriate submittals for an exemption, in accordance with 10 CFR 50.12, from the requirements of 10 CFR 50.82(a)(8)(i)(A) in order to use the decommissioning trust funds for non-decommissioning related expenses, as defined by 10 CFR 50.2.The total cost projected for license termination (in accordance with 10 CFR 50.75) for the deferred decommissioning alternative (SAFSTOR) is shown at the bottom of Table 19 Total decommissioning funds available include Progress Energy Florida's share (91.8%) as well as that of the nine minority owners: City of Alachua, City of Bushnell, City of Gainesville, City of Kissimmee, City of Leesburg, City of Ocala, Orlando Utilities Commission, Seminole Electric Cooperative, and City of New Smyrna Beach TLG Services, Inc.
Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Page xv of xxii 1 ($753.717million).
The schedule of expenditures for license termination activities is provided in Table 2. Table 3 provides the details of the proposed funding plan for decommissioning Crystal River based on a 2% real rate of return on the decommissioning trust fund. As shown in Table 3, the current trust funds (as of September 30, 2011) are sufficient to accomplish the intended tasks and terminate the operating license for Crystal River. The analysis also shows a surplus in the fund at the completion of decommissioning.
This surplus could be made available to fund other activities at the site (e.g., spent fuel management and/or restoration activities), recognizing that the licensee would need to make the appropriate submittals for an exemption in accordance with 10 CFR 50.12 from the requirements of 10 CFR 50.82(a)(8)(i)(A) in order to use the decommissioning trust funds for non-decommissioning related expenses, as defined by 10 CFR 50.2.Summary The cost to decommission Crystal River assumes the removal of all contaminated and activated plant components and structural materials such that the owner may then have unrestricted use of the site with no further requirements for an operating license.Low-level radioactive waste, other than GTCC waste, is sent to a commercial processor for treatment/conditioning or to a controlled disposal facility.Decommissioning is accomplished within the 60-year period required by current NRC regulations.
In the interim, the spent fuel remains in storage at the site until such time that the transfer to a DOE facility is complete.
Once emptied, the 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 major cost components are also identified in the cost summary provided at the end of this section.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.The "Spent Fuel Management" subcategory contains costs associated with the containerization and transfer of spent fuel to the ISFSI and the management of the TLG Services, Inc.

This includes structures never exposed to radioactive materials, as well as those facilities that have been decontaminated to appropriate levels. Structures are removed to three feet below grade and backfilled.
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, an owner may decide to remove non-contaminated structures early in the project to improve access to highly contaminated facilities or plant components.
In these instances, the non-contaminated removal costs could be reassigned from Site Restoration to an NRC License Termination support activity.
However, in general, the allocations represent a reasonable accounting of those costs that can be expected to be incurred for the specific subcomponents of the total estimated program cost, if executed as described.
As noted within this document, the estimate is developed and costs are presented in 2011 dollars. As such, the estimate does not reflect the escalation of costs (due to inflationary and market forces) over the remaining operating life of the reactor or during the decommissioning period.TLG Services, Inc.

Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 1, Page 1 of 9 1. INTRODUCTION This report presents an estimate of the cost to decommission the Crystal River Unit 3 Nuclear Generating Plant, (Crystal River) following a scheduled cessation of plant operations.
The analysis relies upon site-specific, technical information from an earlier evaluation prepared in 2008,[1]*
updated to reflect current assumptions pertaining to the disposition of the nuclear unit and relevant industry experience in undertaking such projects.Pursuant to 10 CFR 50.75(f)(3),[
2 1 each power reactor licensee shall at or about 5 years prior to the projected end of operations submit a preliminary decommissioning cost estimate which includes an up-to-date assessment of the major factors that could affect the cost to decommission.
Progress Energy Florida, Inc. (Progress Energy) is submitting this estimate to comply with the requirements of 10 CFR 50.75(f)(3).
Progress Energy has not determined or committed to a specific decommissioning approach for Crystal River at this time. However, it is Progress Energy's current plan for purposes of demonstrating the adequacy of finding to meet regulatory requirements to use the SAFSTOR decommissioning option based on the current license expiration date. License renewal is likely to require a need to revise this preliminary plan.The current estimate is designed to provide Progress Energy, the plant's majority owner, with sufficient information to assess its financial obligations, as they pertain to the eventual 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 Crystal River, to provide a sequence or schedule for the associated activities, and to develop waste stream projections from the decontamination and dismantling activities.
The plant was issued its operating license in December 1976. The license currently expires in 2016. An application for the renewal of Facility Operating License No. DPR-72, for an additional 20-year period, was submitted to the Nuclear Regulatory Commission (NRC) on December 16, 2008. The application is currently under review. So, for the purposes of this study, the final* References provided in Section 7 of the document TLG Services, Inc.
Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 1, Page 2 of 9 shutdown date (license expiration) is assumed to on December 3, 2016 or 40 years from the original license issue.1.2 SITE DESCRIPTION The Crystal River 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.The generating unit has 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 is converted to electrical energy by the steam and power conversion system. A turbine-generator system converts 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 are operated in a closed feedwater cycle, which condenses the steam; the heated feedwater is returned to the steam generators.
Heat rejected in the main condensers is removed by the circulating water system. The condenser circulating water is taken from and returned to the Gulf of Mexico through the intake and discharge canals, respectively.

Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 1, Page 3 of 9 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,"[
4 1 which provided additional guidance to the licensees of nuclear facilities on the financial methods acceptable to the NRC staff for complying with the requirements of the rule. The regulatory guide addressed the funding requirements and provided guidance on the content and form of the financial assurance mechanisms indicated in the rule.The rule defined three decommissioning alternatives as being acceptable to the NRC: DECON, SAFSTOR, and ENTOMB. The DECON alternative assumes that any contaminated or activated portion of the plant's systems, structures and facilities are removed or decontaminated to levels that permit the site to be released for unrestricted use shortly after the cessation of plant operations.
The rule also placed limits on the time allowed to complete the decommissioning process. For SAFSTOR, the process is restricted in overall duration to 60 years, unless it can be shown that a longer duration is necessary to protect public health and safety. The guidelines for ENTOMB are similar, providing the NRC with both sufficient leverage and flexibility to ensure that these deferred options are only used in situations where it is reasonable and consistent with the definition of decommissioning.
At the conclusion of a 60-year dormancy period (or longer for ENTOMB if the NRC approves such a case), the site would still require significant remediation to meet the unrestricted release limits for license termination.
The ENTOMB alternative has not been viewed as a viable option for power reactors due to the significant time required to isolate the long-lived radionuclides for decay to permissible levels. With rulemaking permitting the controlled release of a site,[5 I 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 TLG Services, Inc.
Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 1, Page 4 of 9 entombments.[61 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.[7] 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 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 NWPA provided that DOE would enter into contracts with utilities in which DOE would promise to take the utilities' spent fuel and high-level radioactive waste and utilities would pay the cost of the disposition services for that material.
NWPA, TLG Services, Inc.
Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 1, Page 5 of 9 along with the individual contracts with the utilities, specified that the DOE was to begin accepting spent fuel by January 31, 1998.Since the original legislation, the DOE has announced several delays in the program schedule.
By January 1998, the DOE had failed to accept any spent fuel or high level waste, as required by the NWPA and utility contracts.
Delays continue and, as a result, generators have initiated legal action against the DOE in an attempt to obtain compensation for DOE's breach of contract.Completion of the decommissioning process is dependent upon the DOE's ability to remove spent fuel from the site in a timely manner.DOE's repository program assumes that spent fuel allocations will be accepted for disposal from the nation's commercial nuclear plants, with limited exceptions, in the order (the "queue") in which it was discharged from the reactor. Progress Energy's current spent fuel management plan for the Crystal River spent fuel is based in general upon: 1) a 2020 start date for DOE initiating transfer of commercial spent fuel to a federal facility and 2) expectations for spent fuel receipt by the DOE for the Crystal River fuel. Fuel could be completely removed from the site as early as 2057, based on an oldest fuel first priority, and the DOE achieving an annual rate of transfer (3,000 metric tons of uranium year)as reflected in DOE's latest Acceptance Priority Ranking and Annual Capacity Report dated June 2004 (DOE/RW-0567).
The assumed 2020 DOE start date is nominally based on the last position stated by the DOE. On July 15, 2008, the then-Director of the DOE's Office of Civilian Radioactive Waste Management testified before Congress that DOE "could be ready to begin accepting spent nuclear fuel by 2020," but his statement was based on continued program funding.[9 1 The current administration has cut the budget for the geological repository program, but the administration has also appointed a Blue Ribbon Commission on America's Nuclear Future to make recommendations for a new plan for nuclear waste disposal.
That Commission's charter includes a requirement that the Commission consider "options for safe storage of used nuclear fuel while final disposition pathways are selected and deployed." Progress Energy believes that one or more monitored retrievable storage facilities could be put into place following a Blue Ribbon Commission recommendation for the same, within a relatively short time frame, at least by 2020. For example, a facility such as that licensed by the NRC to Private Fuel Storage could be used by the DOE to store fuel until a final disposition is determined.

Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 1, Page 6 of 9 It is generally necessary that spent fuel be cooled and stored for a minimum period at the generating site prior to transfer.
As such, the NRC requires that licensees establish a program to manage and provide funding for the management of all irradiated fuel at the reactor site until title of the fuel is transferred to the Secretary of Energy, pursuant to 10 CFR Part 50.54(bb).[
1 0 1 This requirement is prepared for through inclusion of certain cost elements in the decommissioning estimate, for example, associated with the isolation and continued operation of the spent fuel pool and the ISFSI.The spent fuel pool is expected to contain freshly discharged assemblies (from the most recent refueling cycles) as well as the final reactor core at shutdown.
Over the following six and one half years the assemblies are packaged into multipurpose canisters for transfer to the DOE or to the ISFSI for interim storage. It is assumed that this period provides the necessary cooling for the final core to meet the transport and/or storage requirements for decay heat.An ISFSI, operated under a Part 50 General License (in accordance with 10 CFR 72, Subpart K [111), is in the process of being constructed to support continued plant operations.
The facility is assumed to be available to support future decommissioning operations.
Once the wet storage pool is emptied, the auxiliary building can be prepared for long-term storage.Progress Energy's position is that the DOE has a contractual obligation to accept Crystal River's 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. However, at this time, including the cost of storing spent fuel in this study is the most reasonable approach because it insures the availability of sufficient decommissioning funds at the end of the station's life if, contrary to its contractual obligation, the DOE has not performed earlier.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,[121 and its Amendments of 1985,[131 the states became ultimately responsible for the TLG Services, Inc.
Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 1, Page 7 of 9 disposition of low-level radioactive waste generated within their own borders.The disposal facility in Barnwell, South Carolina is currently closed to generators outside the Atlantic Compact (comprising the states of Connecticut, New Jersey and South Carolina).
The commercial disposal facility on the Hanford Nuclear Reservation near Richland, Washington accepts low-level radioactive waste from the Northwest (Alaska, Hawaii, Idaho, Montana, Oregon, Utah, Washington and Wyoming) and Rocky Mountain (Colorado, Nevada, and New Mexico) Compact states. This leaves EnergySolutions' disposal facility in Clive, Utah as the only available option for the disposal of the majority of the low-level radioactive waste generated in decommissioning Crystal River (the Texas facility has limited the importation of waste from outside the Texas Compact).For the purpose of this analysis, Progress Energy's "Life of Plant Agreement" with EnergySolutions is used as the basis for estimating the disposal cost for the majority of the radioactive waste (Class A [141).EnergySolutions does not have a license to dispose of the more highly radioactive waste (Classes B and C), for example, generated in the dismantling of the reactor vessel.The Texas Commission on Environmental Quality (TCEQ), the environmental agency for the state, is responsible for the licensing of a low-level radioactive waste disposal facility for the Texas Compact. The agency granted Waste Control Specialists (WCS) a disposal license in 2009 and approval to commence construction in early 2011. Construction of the disposal facility is now essentially complete and the facility was declared operational in November 2011. However, to date, the TCEQ has only published interim disposal rates for the facility, in advance of the formal disposal rate-setting process, and only for Compact generators.
As a proxy, disposition of the Class B and C waste is based upon the last published rate schedule for non-compact waste for the Barnwell facility.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 (Greater-than-Class C or 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 TLG Services, Inc.
Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 1, Page 8 of 9 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, GTCC is packaged in the same canisters used for spent fuel. The GTCC material is shipped directly to a DOE facility as it is generated.
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 for Crystal River 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,"[
1 5 1 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 Crystal River 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 TLG Services, Inc.
Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 1, Page 9 of 9 Response, Compensation, and Liability Act (CERCLA or Superfund).[
1 6 1 An additional and separate limit of 4 millirem per year, as defined in 40 CFR § 141.16, is applied to drinking water.[1 7 1 On October 9, 2002, the NRC signed an agreement with the EPA on the radiological decommissioning and decontamination of NRC-licensed sites. The Memorandum of Understanding (MOU)[1 8] provides that EPA will defer exercise of authority under CERCLA for the majority of facilities decommissioned under NRC authority.
The MOU also includes provisions for NRC and EPA consultation for certain sites when, at the time of license termination, (1) groundwater contamination exceeds EPA-permitted levels; (2) NRC contemplates restricted release of the site; and/or (3) residual radioactive soil concentrations exceed levels defined in the MOU.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.

SAFSTOR DECOMMISSIONING ALTERNATIVE A detailed cost estimate was developed to decommission the Crystal River 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 Crystal River is also divided into phases or periods; however, demarcation of the phases is based upon major milestones within the project or significant changes in the projected expenditures.
2.1 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 is performed.
Access to contaminated areas is secured to provide controlled access for inspection and maintenance.
Preparations for long-term storage include the planning for permanent defueling of the reactor, revision of technical specifications appropriate to the operating conditions and requirements, a characterization of the facility and major components, and the development of the PSDAR.TLG Services, Inc.
Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 2, Page 2 of 8 The process of placing the plant in safe-storage includes, but is not limited to, the following activities:
- Defueling of the reactor vessel." Isolation of the spent fuel pool and fuel handling systems so that safe-storage operations may commence on the balance of the plant. The pool will remain operational for approximately six and one-half years following the cessation of operations before the inventory resident at shutdown can be completely transferred to the ISFSI. This activity may be carried out by plant personnel in accordance with existing operating technical specifications.
Activities are scheduled around the fuel handling systems to the greatest extent possible.* Draining and de-energizing of the non-contaminated systems not required to support continued site operations or maintenance." Disposing of contaminated filter elements and resin beds not required for processing wastes from layup activities or for future dormancy operations.
- Draining of the reactor vessel, with the internals left in place and the vessel head secured.* Draining and de-energizing non-essential, contaminated systems with decontamination as required for future maintenance and inspection.
- Preparing lighting and alarm systems whose continued use is required; de-energizing portions of fire protection, electric power, and HVAC systems whose continued use is not required.* Cleaning of the loose surface contamination from building access pathways.* Performing an interim radiation survey of plant, posting warning signs where appropriate.
Erecting physical barriers and/or securing all access to radioactive or contaminated areas, except as required for inspection and maintenance.
Installing security and surveillance monitoring equipment and relocating security fence around secured structures, 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 TLG Services, Inc.
Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 2, Page 3 of 8 structural integrity, and a site environmental and radiation monitoring program. Resident maintenance personnel perform equipment maintenance, inspection activities, routine services to maintain safe conditions, adequate lighting, heating, and ventilation, and periodic preventive maintenance on essential site services.An environmental surveillance program is carried out during the dormancy period to ensure that releases of radioactive material to the environment are prevented and/or detected and controlled.
Appropriate emergency procedures are established and initiated for potential releases that exceed prescribed limits. The environmental surveillance program constitutes an abbreviated version of the program in effect during normal plant operations.
Security during the dormancy period is conducted primarily to prevent unauthorized entry and to protect the public from the consequences of its own actions. The security fence, sensors, alarms, and other surveillance equipment provide security.
Fire and radiation alarms are also monitored and maintained.
The spent fuel storage pool is emptied within six and one-half years of the cessation of operations.
The transfer of the spent fuel from the ISFSI to a DOE facility begins in 2024 and continues throughout the dormancy period until completed in 2057. Once emptied, the ISFSI is secured for storage and decommissioned along with the power block structures in Period 4.After an optional period of storage (such that license termination is accomplished within 60 years of final shutdown), it is required that the licensee submit an application to terminate the license, along with an LTP, thereby initiating the third phase.2.3 PERIOD 3 -PREPARATIONS FOR DECOMMISSIONING Prior to the commencement of decommissioning operations, preparations are undertaken to reactivate site services and prepare for decommissioning.
Preparations include engineering and planning, a detailed site characterization, and the assembly of a decommissioning management organization.
Final planning for activities and the writing of activity specifications and detailed procedures are also initiated at this time.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, TLG Services, Inc.
Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 2, Page 4 of 8 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.
Variations in the length of the dormancy period are expected to have little effect upon the quantities of radioactive wastes generated from system and structure removal operations.
Given the levels of radioactivity and spectrum of radionuclides expected from forty years of plant operation, no plant process system identified as being contaminated upon final shutdown will become releasable due to the decay period alone, i.e., there is no significant reduction in the waste generated from the decommissioning activities.
However, due to the lower activity levels, a greater percentage of the waste volume can be designated for off-site processing and recovery.The delay in decommissioning also yields lower working area radiation levels.As such, the estimate for this delayed scenario incorporates reduced ALARA controls for the SAFSTOR's lower occupational exposure potential.
2.4 PERIOD 4 -DEFERRED 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 60Co will decrease during the dormancy period, the internal components of the reactor vessel will still exhibit sufficiently high radiation dose rates to require remote sectioning under water due to the presence of long-lived radionuclides such as 94Nb, 5 9 Ni, and 6 3 Ni. Therefore, the remote dismantling procedures would still be employed during this scenario.
Portions of the biological shield will still be radioactive due to the presence of activated trace elements with long half-lives (1 5 2 Eu and 1 5 4 Eu). 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: TLG Services, Inc.
Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 2, Page 5 of 8* Construction of temporary facilities and/or modification of existing facilities to support dismantling activities.
This may include a centralized processing area to facilitate equipment removal and component preparations for off-site disposal." Reconfiguration and modification of site structures and facilities as needed to support decommissioning operations.
This may include the upgrading of roads (on- and off-site) to facilitate hauling and transport.
Modifications may be required to the reactor building to facilitate access of large/heavy equipment.
Modifications may also be required to the refueling area of the reactor building to support the segmentation of the reactor vessel internals and component extraction.
- Design and fabrication of temporary and permanent shielding to support removal and transportation activities, construction of contamination control envelopes, and the procurement of specialty tooling.* 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. Segmentation of the vessel closure head." Removal and segmentation of the upper internals assemblies.
Segmentation will maximize the loading of the shielded transport casks, i.e., by weight and activity.
The operations are conducted under water using remotely operated tooling and contamination controls.* Disassembly and segmentation of the remaining reactor internals, including the core shroud and lower core support assembly.
Some material is expected to exceed Class C disposal requirements.
As such, the segments will be packaged in modified fuel storage canisters for geologic disposal.* Segmentation of the reactor vessel. A shielded platform is installed for segmentation as cutting operations are performed in-air using remotely operated equipment within a contamination control envelope.
The water level is maintained just below the cut to minimize the working area dose rates. Segments are transferred in-air to containers that are stored under water, for example, in an isolated area of the refueling canal." Removal of the activated portions of the concrete biological shield and accessible contaminated concrete surfaces.
If dictated by the steam generator and pressurizer removal scenarios, those portions of the TLG Services, Inc.
Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 2, Page 6 of 8 associated cubicles necessary for access and component extraction are removed.* Removal of the steam generators and pressurizer for material recovery and controlled disposal.
The generators will be moved to an on-site processing center and prepared for transport to the disposal site. To facilitate transport, the generators are cut in half, across the tube bundle. The exposed ends are capped and sealed. The segments can serve as their own burial containers provided that all penetrations are properly sealed and the internal contaminants are stabilized.
A similar process will be used to prepare the retired units for disposal.
The pressurizer is 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).* 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 facility.
Radiation and contamination controls will be utilized until residual levels indicate that the structures and equipment can be released for unrestricted access and conventional demolition.
This activity may necessitate the dismantling and disposition of most of the systems and components (both clean and contaminated) located within these buildings.
This activity facilitates surface decontamination and subsequent verification surveys required prior to obtaining release for demolition.
Routing of material removed in the decontamination and dismantling to a central processing area. Material certified to be free of contamination is released for unrestricted disposition, e.g., as scrap, recycle, or general disposal.
Contaminated material is characterized and segregated for additional off-site processing (disassembly, chemical cleaning, volume reduction, and waste treatment), and/or packaged for controlled disposal at a low-level radioactive waste disposal facility.Incorporated into the LTP is the Final Survey Plan. This plan identifies the radiological surveys to be performed once the decontamination activities are completed and is developed using the guidance provided in the "Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM)."[19]
This document incorporates the statistical approaches to survey design and data TLG Services, Inc.
Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 2, Page 7 of 8 interpretation used by the EPA. It also identifies state-of-the-art, commercially available instrumentation and procedures for conducting radiological surveys.Use of this guidance ensures that the surveys are conducted in a manner that provides a high degree of confidence that applicable NRC criteria are satisfied.
Once the survey is complete, the results are provided to the NRC in a format that can be verified.
The NRC then reviews and evaluates the information, performs an independent confirmation of radiological site conditions, and makes a determination on the requested change to the operating license (that would release the property, exclusive of the ISFSI, for unrestricted use).The NRC will terminate the operating license if it determines that site remediation has been performed in accordance with the LTP, and that the terminal radiation survey and associated documentation demonstrate that the facility is suitable for release.2.5 PERIOD 5 -SITE RESTORATION Following completion of decommissioning operations, site restoration activities will begin. Efficient removal of the contaminated materials and verification that residual radionuclide concentrations are below the NRC limits will result in substantial damage to many of the structures.
Although performed in a controlled and safe manner, the blasting, coring, drilling, scarification (surface removal), and the other decontamination activities will substantially degrade power block structures.
Under certain circumstances, verifying that subsurface radionuclide concentrations meet NRC site release requirements will require removal of grade slabs and lower floors, potentially weakening footings and structural supports.
This removal activity will be necessary for those facilities and plant areas where historical records, when available, indicate the potential for radionuclides having been present in the soil, where system failures have been recorded, or where it is required to confirm that subsurface process and drain lines were not breached over the operating life of the station.Prompt dismantling of site structures is clearly the most appropriate and cost-effective option. It is unreasonable to anticipate that these structures would be repaired and preserved after the radiological contamination is removed. The cost to dismantle site structures with a work force already mobilized on site is more efficient than if the process were deferred.
Site facilities quickly degrade without maintenance, adding additional expense and creating potential hazards to the public as well as to future workers. Abandonment creates a breeding ground for vermin infestation as well as other biological hazards.This cost study presumes that non-essential structures and site facilities are dismantled as a continuation of the decommissioning activity.

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.

COST ESTIMATE The cost estimate prepared for decommissioning Crystal River 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 2008 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,"[
2 0 1 and the DOE "Decommissioning Handbook."[
2 1] 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.[2 2 1 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 Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 3, Page 2 of 26 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 10% to 50%* Radiation/ALARA Factor 10% to 37%* Protective Clothing Factor 10% 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 Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 3, Page 3 of 26 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.
Inherent in any cost estimate that does not rely on historical data is the inability to specify the precise source of costs imposed by factors such as tool breakage, accidents, illnesses, weather delays, and labor stoppages.
In the DECCER cost model, contingency fulfills this role. Contingency is added to each line item to account for costs that are difficult or impossible to develop analytically.
Such costs are historically inevitable over the duration of a job of this magnitude; therefore, this cost analysis includes funds to cover these types of expenses.3.3.1 Contingency The activity-and period-dependent costs are combined to develop the total decommissioning cost. A contingency is then applied on a line-item basis, using one or more of the contingency types listed in the AIF/NESP-036 study. "Contingencies" are defined in the American Association of Cost Engineers "Project and Cost Engineers' Handbook"[
2 3] 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 Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 3, Page 4 of 26 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.

Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 3, Page 5 of 26 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:* Transition activities and costs: ancillary expenses associated with eliminating 50% to 80% of the site labor force shortly after the cessation of plant operations, added cost for worker separation packages throughout the decommissioning program, national or company-mandated retraining, and retention incentives for key personnel." Delays in approval of the decommissioning plan due to intervention, public participation in local community meetings, legal challenges, and national and local hearings.* Changes in the project work scope from the baseline estimate, involving the discovery of unexpected levels of contaminants, contamination in places not previously expected, contaminated soil previously undiscovered (either radioactive or hazardous material contamination), variations in plant inventory or configuration not indicated by the as-built drawings.* Regulatory changes, for example, affecting worker health and safety, site release criteria, waste transportation, and disposal.* Policy decisions altering national commitments (e.g., in the ability to accommodate certain waste forms for disposition), or in the timetable for such, for example, the start and rate of acceptance of spent fuel by the DOE." 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 TLG Services, Inc.

Consequently, the areas of uncertainty or risk are revisited periodically and addressed through repeated revisions or updates of the base estimate.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 Crystal River. Ultimate disposition of the spent fuel is within the province of the DOE's Waste Management System, as defined by the Nuclear Waste Policy Act. As such, the disposal cost is financed by a 1 mill/kWhr surcharge paid into the DOE's waste fund during operations.
However, the NRC requires licensees to establish a program to manage and provide funding for the management of all irradiated fuel at the reactor 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 the DOE's most recently published annual acceptance rates of 400 MTU/year for year 1, 3,800 MTU total for years 2 through 4 and 3,000 MTU/year for year 5 and beyond.[241 The DOE contracts provide mechanisms for altering the oldest fuel first allocation scheme, including emergency deliveries, exchanges of allocations amongst utilities and the option of providing priority acceptance from permanently shutdown nuclear reactors.Because it is unclear how these mechanisms may operate once DOE begins accepting spent fuel from commercial reactors, this study assumes that DOE will accept spent fuel in an oldest fuel first order.ISFSI The ISFSI, constructed to support plant operations, will continue to operate until such time that the transfer of spent fuel to the DOE can be completed.
Assuming that DOE commences repository operation in TLG Services, Inc.
Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 3, Page 7 of 26 2020, Crystal River fuel is projected to be first removed from the site beginning in 2024. The process is expected to be completed by the year 2057, based upon the current shutdown date. Based upon the expected completion date for fuel transfer, the ISFSI will be emptied prior to the commencement of decommissioning operations.
Operation and maintenance costs for the ISFSI are included within the estimate and address the cost for staffing the facility, as well as security, insurance, and licensing fees. The estimate includes the costs to purchase, load, and transfer the fuel storage canisters.
Costs are also provided for the final disposition of the facility once the transfer is complete.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 capacity.
A unit cost of approximately
$1.46 million is used for pricing the internal multi-purpose canister (MPC) and the horizontal concrete storage module.Canister Loading and Transfer An average cost of $700,000 is used 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. For estimating purposes, $100,000 is used to estimate the unit cost to transfer the fuel from the ISFSI into a DOE transport cask.Operations and Maintenance An annual cost (excluding labor) of approximately
$764,000 and $89,000 are used for operation and maintenance of the spent fuel pool and the ISFSI, respectively.
Pool operations are expected to continue approximately six and one-half years after the cessation of operations.
ISFSI operating costs are based upon a 41 year period of operations following plant shutdown.ISFSI Design Considerations 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.
The final core off load, equivalent to 6 modules, are TLG Services, Inc.
Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 3, Page 8 of 26 assumed to have some level of neutron-induced activation as a result of the long-term storage of the fuel (i.e., to levels exceeding free-release limits). The steel support structure is assumed to be removed from these modules 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.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. Although there are strong arguments that GTCC waste is covered by the spent fuel contract with DOE and the fees being paid pursuant to that contract, DOE has taken the position that GTCC waste is not covered by that contract or its fees and that utilities, including Progress Energy, will have to pay an additional fee for the disposal of their GTCC 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.
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.
TLG Services, Inc.
Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 3, Page 9 of 26 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,* there were no man-made or natural terrain features between the plant site and the disposal location that could produce a large drop, and* transport speeds were very low, limited by the overland transport vehicle and the river barge.As a member of the Northwest Compact, PGE had a site available for disposal of the package -the US Ecology facility in Washington State.The characteristics of this arid site proved favorable in demonstrating compliance with land disposal regulations.
It is not known whether this option will be available when the Crystal River unit ceases operation.
Future viability of this option will depend upon the ultimate location of the disposal site, as well as the disposal site licensee's ability to accept highly radioactive packages and effectively isolate them from the environment.
Consequently, the study assumes the reactor vessel will require segmentation, as a bounding condition.
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 is not included.TLG Services, Inc.
Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 3, Page 10 of 26 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. The interior volume is filled with low-density cellular concrete for stabilization of the internal contamination.
Each component is then loaded onto a rail car for transport to the disposal facility.Reactor coolant piping is cut from the reactor vessel once the water level in the ve'ssel (used for personnel shielding during dismantling and cutting operations in and around the vessel) is dropped below the nozzle zone. The piping is boxed and transported by shielded van. The reactor coolant pumps and motors are lifted out intact, packaged, and transported for processing and/or disposal.3.4.4 Retired Components The estimate includes the cost to dispose of the retired reactor closure head expected to be in storage at the site upon the cessation of plant operations.
The component is segmented, with the segments placed in sea-land containers or custom containers for disposal.
The retired steam generators, currently in storage at the site, will be segmented to facilitate transportation.
TLG Services, Inc.
Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 3, Page 11 of 26 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 49.1251 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., 1 3 7 Cs, 9 0 Sr, or transuranics) has been prevented from reaching levels exceeding those that permit the major reactor components to be shipped under current transportation regulations and disposal requirements.
Transport of the highly activated metal, produced in the segmentation of the reactor vessel and internal components, will be by shielded truck cask. Cask shipments may exceed 95,000 pounds, including vessel segment(s), supplementary shielding, cask tie-downs, and tractor-trailer. The maximum level of activity per shipment assumed permissible was based upon the license limits of the available shielded transport casks. The segmentation scheme for the vessel and internal segments is designed to meet these limits.TLG Services, Inc.
Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 3, Page 12 of 26 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.[2 6 1 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.
The more highly activated reactor components will be shipped in reusable, shielded truck casks with disposable liners. In calculating disposal costs, the burial fees are applied against the liner volume, as well as the special handling requirements of the payload. Packaging efficiencies are lower for the highly activated materials (greater than Type A quantity waste), where high concentrations of gamma-emitting radionuclides limit the capacity of the shipping canisters.
TLG Services, Inc.
Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 3, Page 13 of 26 Disposal fees are based upon estimated charges, with surcharges added for the highly activated components, for example, generated in the segmentation of the reactor vessel. The cost to dispose of the majority of the material generated from the decontamination and dismantling activities is based upon the current cost for disposal at EnergySolutions facility in Clive, Utah. As a proxy, disposition of the Class B and C waste is based upon the last published rate schedule for non-compact waste for the Barnwell facility.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 grade. Concrete rubble generated from demolition activities is processed and made available as clean fill for the power block foundations.
Excess construction debris is trucked off site as an alternative to onsite disposal.
The excavations will be regraded such that the power block area will have a final contour consistent with adjacent surroundings.
Certain facilities, which have continued use or value (e.g., the switchyard) are left intact.The estimate includes the remediation of the west settling pond (approximately (500 cubic yards). This assumption may be affected by continued plant operations and/or future regulatory actions, such as the development of site-specific release criteria.
Costs are also included 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.TLG Services, Inc.
Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 3, Page 14 of 26 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 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.Progress Energy, 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.
Personnel costs are based upon average salary information provided by Progress Energy. Overhead costs are included for site and corporate support, reduced commensurate with the staffing of the project.Security, while reduced from operating levels, is maintained throughout the decommissioning for access control, material control, and to safeguard the spent fuel.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., 1 3 7 Cs, 9 0 Sr, or transuranics) has been prevented from reaching levels exceeding those TLG Services, Inc.
Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 3, Page 15 of 26 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.[271 Actual estimates are derived from the curie/gram values contained therein and adjusted for the different mass of the Crystal River components, projected operating life, and period of decay. Additional short-lived isotopes were derived from NUREG/CR-0130[28]
and NUREG/CR-0672,[291 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.Activation of the reactor building is confined to the biological shield.More extensive activation (at very low levels) of the interior structures within reactor buildings has been detected at several reactors and the owners have elected to dispose of the affected material at a controlled facility rather than reuse the material as fill on site or send it to a landfill.
The ultimate disposition of the material removed from the reactor building will depend upon the site release criteria selected, as well as the designated end use for the site.3.5.4 General Transition Activities Existing warehouses are cleared of non-essential material and remain for use by Progress Energy 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.TLG Services, Inc.
Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 3, Page 16 of 26 Scrap and Salvage The existing plant equipment is considered obsolete and suitable for scrap as deadweight quantities only. Progress Energy will make economically reasonable efforts to salvage equipment following final plant shutdown.
However, dismantling techniques assumed by TLG for equipment in this analysis are not consistent with removal techniques required for salvage (resale) of equipment.
Experience has indicated that some buyers wanted equipment stripped down to very specific requirements before they would consider purchase.
This required expensive rework after the equipment had been removed from its installed location.
Since placing a salvage value on this machinery and equipment would be speculative, and the value would be small in comparison to the overall decommissioning expenses, this analysis does not attempt to quantify the value that an owner may realize based upon those efforts.It is assumed, for purposes of this analysis, that any value received from the sale of scrap generated in the dismantling process would be more than offset by the on-site processing costs. The dismantling techniques assumed in the decommissioning 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 release this material.
This assumption is an implicit recognition of scrap value in the disposal of clean metallic waste at no additional cost to the project.Furniture, tools, mobile equipment such as forklifts, trucks, bulldozers, and other property is removed at no cost or credit to the decommissioning project. Disposition may include relocation to other facilities.
Spare parts are also made available for alternative use.Energy For estimating purposes, the plant is assumed to be de-energized, with the exception of those facilities associated with spent fuel storage.Replacement power costs are used to calculate the cost of energy consumed during decommissioning for tooling, lighting, ventilation, and essential services.TLG Services, Inc.
Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 3, Page 17 of 26 Insurance Costs for continuing coverage (nuclear liability and property insurance) following cessation of plant operations and during decommissioning are included and based upon current operating premiums.
Reductions in premiums, throughout the decommissioning process, are based upon the guidance and the limits for coverage defined in the NRC's proposed rulemaking "Financial Protection Requirements for Permanently Shutdown Nuclear Power Reactors."[
3 0° The NRC's financial protection requirements are based on various reactor (and spent fuel)configurations.
Taxes The tax model is based upon the current tax obligation by the owers.Taxes on plant systems and structures are included (at a reduced level)and further reduced as dismantling operations proceed. Taxes are included on the land and the ISFSI (during its operation), throughout the decommissioning timeframe.
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.3.6 COST ESTIMATE
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 construction of an ISFSI, the containerization and transfer of spent fuel to the ISFSI over the six and one-half years of post-shutdown pool operations, and TLG Services, Inc.
Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 3, Page 18 of 26 the management of the ISFSI until such time that the transfer of all fuel from this facility to an off-site location (e.g., geologic repository) is complete."Site Restoration" is used to capture costs associated with the dismantling and demolition of buildings and facilities demonstrated to be free from contamination.
This includes structures never exposed to radioactive materials, as well as those facilities that have been decontaminated to appropriate levels. Structures are removed to a depth of three feet and backfilled to conform to local grade.Decommissioning costs are reported in 2011 dollars. Costs are not inflated, escalated, or discounted over the period of expenditure (or projected lifetime of the plant). The schedule is based upon the detailed activity costs reported in Appendix C, along with the timeline presented in Section 4.TLG Services, Inc.

SCHEDULE ESTIMATE The schedule for the decommissioning scenario considered in this study follow the sequences presented in the AIF/NESP-036 study, with minor changes to reflect recent experience and site-specific constraints.
In addition, the scheduling has been revised to reflect the spent fuel management plan described in Section 3.4.1.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 prepared using the "Microsoft Project Professional 2010" computer software.[
3 1 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 Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 4, Page 2 of 4 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 a 2016 shutdown date. The fuel pool is emptied approximately six and one-half years after shutdown, while ISFSI operations continue until the DOE can complete the transfer of assemblies to its geologic repository.
Deferred decommissioning is assumed to commence so that the operating license is terminated within a 60-year period from the cessation of plant operations.

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 2 1 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 volumes of radioactive waste generated during the various decommissioning activities at the site are shown on a line-item basis in Appendix C, and summarized in Table 5.1. The quantified waste volume summaries shown in these tables are consistent with Part 61 classifications.
The volumes are calculated based on the exterior dimensions for containerized material and on the displaced volume of components serving as their own waste containers.
The reactor vessel and internals are categorized as large quantity shipments and, accordingly, will be shipped in reusable, shielded truck casks with disposable liners.In calculating disposal costs, the burial fees are applied against the liner volume, as well as the special handling requirements .of the payload. Packaging efficiencies are lower for the highly activated materials (greater than Type A quantity waste), where high concentrations of gamma-emitting radionuclides limit the capacity of the shipping canisters.
No process system containing/handling radioactive substances at shutdown is presumed to meet material release criteria by decay alone (i.e., systems radioactive at shutdown will still be radioactive over the time period during which the decommissioning is accomplished, due to the presence of long-lived radionuclides).
While the dose rates decrease with time, radionuclides such as 1 3 7 Cs will still control the disposition requirements.

Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 5, Page 2 of 4 The waste material produced in the decontamination and dismantling of the nuclear unit is primarily generated during Period 4. The assumed disposition of waste material is shown in Figure 5.1. Material that is considered potentially contaminated when removed from the radiological controlled area is sent to processing facilities in Tennessee for conditioning and disposal.
Heavily contaminated components and activated materials are routed for controlled disposal.
The disposal volumes reported in the tables reflect the savings resulting from reprocessing and recycling.
Disposal fees are based upon estimated charges, with surcharges added for the highly activated components, for example, generated in the segmentation of the reactor vessel. The cost to dispose of the majority of the material generated from the decontamination and dismantling activities is based upon the current cost for disposal at EnergySolutions facility in Clive, Utah. Separate rates were used for containerized waste and large components, including the steam generators and reactor coolant pump motors. Demolition debris including miscellaneous steel, scaffolding, and concrete was disposed of at a bulk rate. The decommissioning waste stream also included resins and dry active waste. As a proxy, disposition of the Class B and C waste is based upon the last published rate schedule for non-compact waste for the Barnwell facility.TLG Services, Inc.

Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 6, Page 1 of 4 6. RESULTS The analysis to estimate the cost to decommission Crystal River relied upon the site-specific, technical information developed for a previous analysis prepared in 2008. While not an engineering study, the estimate provides Progress Energy with sufficient information to assess their financial obligations, as they pertain to the eventual 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 for a minimum of six and one half years following the cessation of operations for continued cooling of the assemblies.
An ISFSI will be used to safeguard the spent fuel, once sufficiently cooled, until such time that the DOE can complete the transfer of the assemblies to its repository.
The cost projected for deferred decommissioning (SAFSTOR) is estimated to be$1,077.6 million. The majority of this cost (approximately 70.0%) 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 25.2% is associated with the management, interim storage, and eventual transfer of the spent fuel. The remaining 4.8% is for the demolition of the designated structures and limited restoration of the site.The primary cost contributors, identified in Table 6.1, 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 Progress Energy 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 remain operational for a minimum of six and one half years following the cessation of operations.
The pool will be isolated and an independent spent fuel island created. Over the six and one-TLG Services, Inc.
Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 6, Page 2 of 4 half-year period, the spent fuel will be packaged into transportable steel canisters for interim storage at the ISFSI. Dry storage of the fuel provides additional flexibility in the event the DOE is not able to meet the 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 the newly opened 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 for spent fuel.A significant portion of the metallic waste is designated for additional processing and treatment at an off-site facility.
Processing reduces the volume of material requiring controlled disposal through such techniques and processes as survey and sorting, decontamination, and volume reduction.
The material that cannot be unconditionally released is packaged for controlled disposal at one of the currently operating facilities.
The cost identified in the summary tables for processing is all-inclusive, incorporating the ultimate disposition of the material.Removal costs reflect the labor-intensive nature of the decommissioning process, as well as the management controls required to ensure a safe and successful program.Decontamination and packaging costs also have a large labor component that is based upon prevailing union 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. Prompt demolition reduces future liabilities and can be more cost effective than deferral, due to the deterioration of the facilities (and therefore the working conditions) with time.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.TLG Services, Inc.
Crystal River Unit 3 Nuclear Generating Plant Document P23-1651-001, Rev. 0 Preliminary Decommissioning Cost Estimate Section 6, Page 3 of 4 Decontamination is used to reduce the plant's radiation fields and minimize worker exposure.
Slightly contaminated material or material located within a contaminated area is sent to an off-site processing center, i.e., this analysis does not assume that contaminated plant components and equipment can be decontaminated for uncontrolled release in-situ. Centralized processing centers have proven to be a more economical means of handling the large volumes of material produced in the dismantling of a nuclear 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 are greatly reduced following the final cessation of plant operations, certain administrative functions do need to be maintained either at a basic functional or regulatory level.TLG Services, Inc.
