SUMMARY
This report presents estimates of the cost to decommission the Callaway Energy Center (Callaway) for the selected decommissioning alternatives and scenarios following the scheduled cessation of plant operations. The estimates are designed to provide Ameren Services with sufficient information to assess its financial obligations, as they pertain to the eventual decommissioning of the nuclear unit.
The analysis relies upon site-specific, technical information from an evaluation prepared in 2020,[1] updated to reflect current assumptions pertaining to the disposition of the nuclear unit and relevant industry experience in undertaking such projects. The costs are 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 restoration requirements.
The analysis is not a detailed engineering evaluation, but represents estimates prepared in advance of the detailed engineering required to carry out the decommissioning of the nuclear unit. It may also not reflect the actual plan to decommission Callaway; the plan may differ from the assumptions made in this analysis based on facts that exist at the time of decommissioning.
The 2020 plant inventory, the basis for the decontamination and dismantling requirements and cost, and the decommissioning waste streams, was reviewed for this analysis. There have been no substantive changes made to the plant inventory that would impact the estimated decommissioning costs.
The costs to decommission Callaway for the base scenarios (disposal with low-level radioactive waste processing) are presented at the end of this section. Costs are reported in 2023 dollars and include monies anticipated to be spent for radiological remediation and operating license termination, spent fuel management, and site restoration activities.
A complete discussion of the assumptions relied upon in this analysis is provided in Section 3, along with schedules of annual expenditures for the base scenarios. A sequence of significant project activities is provided in Section 4 with a timeline for each scenario. Detailed cost reports used to generate the summary tables contained 1

Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Page viii of xxi TLG Services, LLC within this document are provided in the appendices along with the costs for the alternative scenario (direct low-level radioactive waste disposal).
Consistent with the 2020 analysis, the current cost estimates assume that the shutdown of the nuclear unit is a scheduled and pre-planned event (e.g., there is no delay in transitioning the plant and workforce from operations or in obtaining regulatory relief from operating requirements, etc.). The estimates include the continued operation of the fuel building as an interim wet fuel storage facility for approximately five and one-half years after operations cease. During this period, it is assumed that the spent fuel residing in the pool will be transferred to a Department of Energy (DOE) federal facility (e.g., a monitored retrievable storage facility). All spent fuel stored on site in the independent spent fuel storage installation (ISFSI) will also be removed by the DOE during this time.
Alternatives and Regulations The ultimate objective of the decommissioning process is to reduce the inventory of contaminated and activated material so that the license can be terminated. The Nuclear Regulatory Commission (NRC or Commission) provided initial decommissioning requirements in its rule adopted on June 27, 1988.[2] In this rule, the NRC set forth financial criteria for decommissioning licensed nuclear power facilities. The regulations addressed planning needs, timing, funding methods, and environmental review requirements for decommissioning. The rule also defined three decommissioning alternatives as being acceptable to the NRC: DECON, SAFSTOR, and ENTOMB.
DECON is defined as "the alternative in which the equipment, structures, and portions of a facility and site containing radioactive contaminants are removed or decontaminated to a level that permits the property to be released for unrestricted use shortly after cessation of operations."[3]
SAFSTOR is defined as "the alternative in which the nuclear facility is placed and maintained in a condition that allows the nuclear facility to be safely stored and subsequently decontaminated (deferred decontamination) to levels that permit release for unrestricted use."[4]
Decommissioning is to be completed within 60 years, although longer 2

Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Page ix of xxi TLG Services, LLC 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."[5] As with the SAFSTOR alternative, decommissioning is currently required to be completed within 60 years, although longer time periods will also be considered when necessary to protect public health and safety.
The 60-year restriction has limited the practicality for the ENTOMB alternative at commercial reactors that generate significant amounts of long-lived radioactive material. In 1997, the Commission directed its staff to re-evaluate this alternative and identify the technical requirements and regulatory actions that would be necessary for entombment to become a viable option.
The resulting evaluation provided several recommendations; however, rulemaking has been deferred pending the completion of additional research studies, for example, on engineered barriers. In a draft regulatory basis document published in March 2017 in support of rulemaking that would amend NRC regulations concerning nuclear plant decommissioning, the NRC staff proposes removing any discussion of the ENTOMB option from existing guidance documents since the method is not deemed practically feasible.
In 1996, the NRC published revisions to the general requirements for decommissioning nuclear power plants to clarify ambiguities and codify procedures and terminology as a means of enhancing efficiency and uniformity in the decommissioning process.[6] The amendments allow for greater public participation and better define the transition process from operations to decommissioning. Regulatory Guide 1.184, issued in July 2000, (as revised in October 2013), further described the methods and procedures that are acceptable to the NRC staff for implementing the requirements of the 1996 revised rule that relate to the initial activities and the major phases of the decommissioning process. The costs and schedules presented in this analysis follow the general guidance and sequence in the amended regulations. The format and content of 5

Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Page x of xxi TLG Services, LLC the estimates is also consistent with the recommendations of Regulatory Guide 1.202, issued in February 2005.[7]
In 2011, the NRC issued regulations to improve decommissioning planning and thereby reduce the likelihood that any current operating facility will become a legacy site.[8] The regulations require licensees to report additional details in their decommissioning cost estimate, including a decommissioning estimate for any on-site ISFSI. Since an ISFSI is required to support continued operation at Callaway, a representative decommissioning cost is included within the DECON and SAFSTOR estimates, and reported separately in Appendix G.
Decommissioning Scenarios Two decommissioning alternatives were evaluated for the Callaway Energy Center.
The scenarios selected are representative of alternatives currently available to the owner and are defined as follows:
- 1. The first scenario assumes that the nuclear unit is promptly decommissioned (DECON alternative) upon the expiration of the current operating license in 2044. Following the permanent cessation of operations, and over the first five and one-half years, the spent fuel is transferred directly from the wet storage pool to the DOE (the fuel stored on the ISFSI is also removed from the site during this time period). Concurrently, the majority of the plant components, including the nuclear steam supply system components, are removed. Once the spent fuel stored in the fuel pool has been transferred off-site, the remaining portions of the power block are decommissioned and the surrounding site is remediated. Following the termination of the operating license, non-essential structures (not designated for reuse) are dismantled.
- 2. In the second scenario, the nuclear unit is placed into safe-storage (SAFSTOR alternative) upon the expiration of the current operating license in 2044. As with the first scenario, the spent fuel is removed from the site (transferred to the DOE) during the first five and one-half years following the permanent cessation of operations. The facility is then placed into safe-storage (with non-essential systems de-energized and 7

The start of decontamination and dismantling activities is deferred to the maximum extent (approximately 50 years from the cessation of operations) such that the license is terminated within the required 60-year period post cessation of operations.
In addition to the two decommissioning alternatives, two low-level radioactive waste disposal options were assessed for each decommissioning alternative: one assuming the use of radioactive waste processing; the other assuming all radioactive waste is directly disposed of by burial. Off-site processing of a portion of the radioactive waste stream is presented as the base option. This option considers the off-site processing of the plant equipment and commodities with low levels of radiological contamination and/or material suspected to be contaminated for volume reduction, decontamination, or segmentation and removal of clean portions prior to disposal as radioactive waste.
The direct disposal option assumes that all contaminated and suspect material is packaged at the site for disposal at a regulated disposal facility. The scenarios are summarized as follows.

This reference describes a unit factor method for determining decommissioning activity costs. The unit factors used in this analysis incorporate site-specific costs and the latest available information on worker productivity in decommissioning.
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.

Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Page xii of xxi TLG Services, LLC The estimates also reflect lessons learned from TLGs 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 Rancho Seco, Trojan, Yankee Rowe, Big Rock Point, Maine Yankee, Humboldt Bay-3, Oyster Creek, Connecticut Yankee, Crystal River, Vermont Yankee, Fort Calhoun, Pilgrim, and Indian Point nuclear units have provided additional insight into the process, the regulatory aspects, and the technical challenges of decommissioning commercial nuclear units.
Contingency Consistent with cost estimating practice, contingencies are applied to the decontamination and dismantling costs developed as "specific provision for unforeseeable elements of cost within the defined project scope, particularly important where previous experience relating estimates and actual costs has shown that unforeseeable events which will increase costs are likely to occur.[10] The cost elements in the estimates are based on ideal conditions; therefore, the types of unforeseeable events that are almost certain to occur in decommissioning, based on industry experience, are addressed through a percentage contingency applied on a line-item basis. This contingency factor is a nearly universal element in all large-scale construction and demolition projects. It should be noted that contingency, as used in this analysis, does not account for price escalation and inflation in the cost of decommissioning over the remaining operating life of the 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,[11] and its Amendments of 1985,[12] the states became ultimately responsible for the disposition of low-level radioactive waste generated within their own borders.

Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Page xiii of xxi TLG Services, LLC With the exception of Texas, no new compact facilities have been successfully sited, licensed, and constructed. The Texas Compact disposal facility is assumed operational and waste is being accepted from generators within the Compact by the operator, Waste Control Specialists (WCS). The facility, located in Andrews, Texas, is also assumed able to accept limited volumes of non-Compact waste.
Disposition of the various waste streams produced by the decommissioning process considered all options and services currently available to Ameren Services. The majority of the low-level radioactive waste designated for controlled disposal (Class A[13]) can be sent to EnergySolutions facility in Clive, Utah. Therefore, disposal costs for Class A waste were based upon Ameren Services agreement with EnergySolutions. This facility is not licensed to receive the higher activity portion (Classes B and C) of the decommissioning waste stream.
The WCS facility is able to receive the Class B and C waste. As such, for this analysis, Class B and C waste was assumed to be shipped to the WCS facility for disposal.
Disposal costs were based upon Ameren Services current agreement with WCS.
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 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.
The DOE issued its Final Environmental Impact Statement for the disposal of GTCC on January 2016. [14]The study evaluated the potential environmental impacts associated with constructing and operating a new facility or using an existing facility, disposal methods, and locations. DOE is awaiting Congressional action on the report and its recommendations. At this time, the federal government has not identified a specific cost for disposing of GTCC or a schedule for acceptance.
For purposes of this analysis only, the GTCC radioactive waste is assumed to be packaged and disposed of in a similar manner as high-level waste and at a cost equivalent to that envisioned for the spent fuel. The GTCC is packaged in canisters compatible with the spent fuel dry storage system and either stored on site or shipped directly to a federal facility as it is generated (depending upon the timing of the decommissioning and whether the spent fuel has been removed from the site prior to 13 Waste is classified in accordance with U.S. Code of Federal Regulations, Title 10, Part 61.55 14 Final Environmental Impact Statement for the Disposal of Greater-Than-Class C (GTCC) Low-Level Radioactive Waste and GTCC-Like Waste (DOE/EIS-0375), January 2016
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Page xiv of xxi TLG Services, LLC the start of decommissioning).
A significant portion of the waste material generated during decommissioning may only be potentially contaminated by radioactive materials. This material 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 direct disposal in a licensed low-level radioactive waste disposal facility can be accomplished through a variety of methods, including analyses and surveys or decontamination to eliminate the portion of waste that does not require disposal as radioactive waste, compaction, incineration or metal melt. The estimates for the base case scenarios reflect the savings from waste recovery/volume reduction.
High-Level Radioactive Waste Management Congress passed the Nuclear Waste Policy Act[15] (NWPA) in 1982, assigning the federal governments long-standing responsibility for disposal of the spent nuclear fuel created by the commercial nuclear generating plants to the DOE. The DOE was to begin accepting spent fuel by January 31, 1998; however, to date no progress in the removal of spent fuel from commercial generating sites has been made.
Today, the country is at an impasse on high-level waste disposal, despite DOEs submittal of its License Application for a geologic repository to the NRC in 2008. The Obama administration eliminated the budget for the repository program while promising to conduct a comprehensive review of policies for managing the back end of the nuclear fuel cycle and make recommendations for a new plan.[16] Towards this goal, the Obama administration appointed a Blue Ribbon Commission on Americas Nuclear Future (Blue Ribbon Commission) to make recommendations for a new plan for nuclear waste disposal. The Blue Ribbon Commissions charter included a requirement that it consider [o]ptions for safe storage of used nuclear fuel while final disposition pathways are selected and deployed.[17]
On January 26, 2012, the Blue Ribbon Commission issued its Report to the Secretary of Energy containing a number of recommendations on nuclear waste disposal. Two of the recommendations that may impact decommissioning planning are:

[T]he United States [should] establish a program that leads to the timely development of one or more consolidated storage facilities[18]
[T]he United States should undertake an integrated nuclear waste management program that leads to the timely development of one or more permanent deep geological facilities for the safe disposal of spent fuel and high-level nuclear waste.[19]
In January 2013, the DOE issued the Strategy for the Management and Disposal of Used Nuclear Fuel and High-Level Radioactive Waste, in response to the recommendations made by the Blue Ribbon Commission and as a framework for moving toward a sustainable program to deploy an integrated system capable of transporting, storing, and disposing of used nuclear fuel...[20] This document states:
With the appropriate authorizations from Congress, the Administration currently plans to implement a program over the next 10 years that:
Sites, designs and licenses, constructs and begins operations of a pilot interim storage facility by 2021 with an initial focus on accepting used nuclear fuel from shut-down reactor sites; Advances toward the siting and licensing of a larger interim storage facility to be available by 2025 that will have sufficient capacity to provide flexibility in the waste management system and allows for acceptance of enough used nuclear fuel to reduce expected government liabilities; and Makes demonstrable progress on the siting and characterization of repository sites to facilitate the availability of a geologic repository by 2048.[21]
The NRCs review of DOEs license application to construct a geologic repository at Yucca Mountain was suspended in 2011 when the Obama administration significantly reduced the budget for completing that work. However, the US Court of Appeals for the District of Columbia Circuit issued a writ of mandamus (in August 2013)[22] ordering NRC to comply with federal law and resume its review of DOE's Yucca Mountain repository license application, to the extent allowed by previously 18 Blue Ribbon Commission on Americas Nuclear Future, Report to the Secretary of Energy, http://www.brc.gov/sites/default/files/documents/brc_finalreport_jan2012.pdf, p. 32, January 2012 32, January 2012 19 Ibid., p.27 20 Strategy for the Management and Disposal of Used Nuclear Fuel and High-Level Radioactive Waste, U.S. DOE, January 11, 2013 21 Ibid., p.2 22 U.S. Court of Appeals for the District Of Columbia Circuit, In Re: Aiken County, et al, Aug. 2013
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Page xvi of xxi TLG Services, LLC appropriated funding for the review. That review was completed with the publication of the five-volume safety evaluation report. A supplement to DOEs environmental impact statement and adjudicatory hearing on the contentions filed by interested parties must be completed before a licensing decision can be made. Although the DOE proposed it would start fuel acceptance in 2025, no progress has been made in the repository program since DOEs 2013 strategy was issued except for the completion of the Yucca Mountain safety evaluation report.
Holtec International submitted a license application to the NRC on March 30, 2017 for a consolidated interim spent fuel storage facility in southeast New Mexico called HI-STORE CISF (Consolidated Interim Storage Facility) under the provisions of 10 CFR Part 72. In May 2023, the NRC issued a license to Holtec to construct and operate a facility to receive, possess, store, and transfer spent nuclear fuel at the HI-STORE CISF.
Waste Control Specialists submitted an application to the NRC on April 28, 2016, to construct and operate a Consolidated Interim Storage Facility (CISF) at its West Texas facility. On April 18, 2017, WCS requested that the NRC temporarily suspend all safety and environmental review activities, as well as public participation activities associated with WCSs license application. In March 2018, WCS and Orano USA, announced their intent to form a joint venture to license the facility. The joint venture, named Interim Storage Partners (ISP), requested that the NRC resume its review of the original CISF license application. Subsequently, in September, 2021, NRC issued a license to ISP for its WCS CISF to construct and operate the facility for spent nuclear fuel and GTCC storage. However, the facility is not yet operational.
Completion of the decommissioning process is dependent upon the DOEs ability to remove spent fuel from the site in a timely manner. In June 2011, Ameren Services and the DOE reached an agreement on a settlement. The terms include payment to Ameren Services for spent fuel storage and related costs through 2010, and thereafter, annual payment of such costs after they are incurred.
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 DOE, pursuant to 10 CFR Part 50.54(bb).[23] The post-shutdown costs incurred to satisfy this requirement include the isolation and continued operation of the spent fuel pool and the ISFSI during the five and one-half years following the cessation of plant operations.

Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Page xvii of xxi TLG Services, LLC At shutdown, the spent fuel pool is expected to contain freshly discharged assemblies (from the most recent refueling cycles) as well as the final reactor core. Over the following five and one-half years all the assemblies are packaged into canisters for transfer to the DOE. It is assumed that this period provides the necessary cooling for the final core to meet the transportation system requirements for decay heat.
Costs are included within the decommissioning estimates for offloading the pool. These costs include the loading of DOE-provided Transport/Aging/Disposal Canister (TADs) and the associated campaign costs to load the canisters into the DOE-provided transport vehicle.
Removal of the fuel from the ISFSI is expected to be fully reimbursable and therefore not addressed in this study. However, the eventual decommissioning of the ISFSI is included.
The estimates described in this analysis were developed with the assumption that the DOE would give priority to removing spent fuel from shutdown sites. The estimates further assume that the spent fuel would be removed from the Callaway site within five and one-half years of the cessation of plant operations (i.e., five and one-half years would provide sufficient cooling time for the spent fuel to meet DOE transportation requirements).
Site Restoration The efficient removal of the contaminated materials at the site may result in damage to many of the site structures. Blasting, coring, drilling, and the other decontamination activities can substantially damage power block structures, potentially weakening the footings and structural supports. It is unreasonable to anticipate that these structures would be repaired and preserved after the radiological contamination is removed. The cost to dismantle site structures with a work force already mobilized is more efficient and less costly than if the process is deferred.
Consequently, this study assumes that non-essential site structures addressed by this analysis are removed, once remediation is complete, to a nominal depth of three feet below the local grade level, wherever possible. The site is then graded and stabilized.
Summary The estimates to decommission Callaway assume 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.
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Page xviii of xxi TLG Services, LLC Low-level radioactive waste, other than GTCC waste, is sent to a commercial processor for treatment/conditioning or directly to a controlled disposal facility.
Decommissioning is accomplished within the 60-year period following permanent cessation of operations required by current NRC regulations. Regardless of the timing of the decommissioning activities, the estimates assume the eventual removal of all the contaminated and activated plant components and structural materials, such that the facility operator may then have unrestricted use of the site with no further requirement for an operating license.
The decommissioning scenarios are described in Section 2. The assumptions are presented in Section 3, along with schedules of annual expenditures for the base case scenario. The major cost contributors are identified in Section 6, with detailed activity costs, waste volumes, and associated workforce requirements delineated in the appendices to this report. The major cost components are also identified in the cost summary provided at the end of this section.
The cost elements in the estimates for the DECON and SAFSTOR alternatives are assigned to one of three subcategories: NRC License Termination (radiological remediation), 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). The cost reported for this subcategory is generally sufficient to terminate the units operating license, recognizing that there may be some additional cost impact from spent fuel management. The License Termination cost subcategory also includes costs to decommission the ISFSI (as required by 10 CFR §72.30). Section 3.4.1 provides the basis for the ISFSI decommissioning cost.
The Spent Fuel Management subcategory is used to accumulate costs associated with operation of the fuel storage pool and the management of the ISFSI until such time that the transfer is complete. It does not include any spent fuel management expenses incurred prior to the cessation of plant operations, nor does it include any costs related to the final disposal of the spent fuel.
Site Restoration is used to capture costs associated with the dismantling and demolition of buildings and facilities demonstrated to be free from contamination. This includes structures never exposed to radioactive materials, as well as those facilities that have been decontaminated to appropriate levels. Structures are removed to a depth of three feet below grade and backfilled to conform to local grade.
It should be noted that the costs assigned to these subcategories are allocations.
Delegation of cost elements is for the purposes of comparison (e.g., with NRC financial guidelines) or to permit specific financial treatment (e.g., Asset Retirement Obligation
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Page xix of xxi TLG Services, LLC determinations). In reality, there can be considerable interaction between the activities in the three subcategories. For example, an owner may decide to remove non-contaminated structures early in the project to improve access to highly contaminated facilities or plant components. In these instances, the non-contaminated removal costs could be reassigned from Site Restoration to an NRC License Termination support activity. However, in general, the allocations represent a reasonable accounting of those costs that can be expected to be incurred for the specific subcomponents of the total estimated program cost, if executed as described.
As noted within this document, the estimates were developed and costs are presented in 2023 dollars. As such, the estimates do not reflect the escalation of costs (due to inflationary and market forces) over the remaining operating life of the reactor or during the decommissioning period.
For the purposes of this analysis, the costs presented in the following tables reflect the use of off-site low-level radioactive waste processing to minimize the volume designated for controlled disposal. Costs for the direct disposal of the low-level radioactive waste (without processing) are presented in the appendices (E and F).

- 1. INTRODUCTION This report presents estimates of the costs to decommission the Callaway Energy Center (Callaway) for the selected decommissioning alternatives and scenarios following the scheduled cessation of plant operations. The estimates are designed to provide Ameren Services with sufficient information to assess its financial obligations, as they pertain to the eventual decommissioning of the nuclear unit.
The analysis relies upon site-specific, technical information from an earlier evaluation prepared in 2020,[1]* updated to reflect current assumptions pertaining to the disposition of the nuclear station and relevant industry experience in undertaking such projects. The costs are 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 restoration requirements.
The analysis is not a detailed engineering evaluation, but rather estimates prepared in advance of the detailed engineering required to carry out the decommissioning of the nuclear unit. It may also not reflect the actual plan to decommission Callaway; the plan may differ from the assumptions made in this analysis based on facts that exist at the time of decommissioning.
The 2020 plant inventory, the basis for the decontamination and dismantling requirements and cost, and the decommissioning waste streams, were reviewed for this analysis. There were no substantive changes made to the plant inventory (that would impact decommissioning).
1.1 OBJECTIVES OF STUDY The objectives of this study were to prepare comprehensive estimates of the costs to decommission Callaway, to provide a sequence or schedule for the associated activities, and to develop waste stream projections from the decontamination and dismantling activities.
An operating license was issued for Callaway in 1984 for a 40 year operating period. On December 19, 2011, Ameren Services submitted a request for renewal of the operating license for an additional period of 20 years. On March 6, 2015, the Nuclear Regulatory Commission (NRC) renewed the operating license through October 18, 2044.

Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section1, Page 2 of 10 TLG Services, LLC For the purpose of this analysis, the base estimates reflect plant decommissioning at the expiration of its current operating license (2044) and the use of off-site low-level radioactive waste processing to minimize the volume designated for controlled disposal.
1.2 SITE DESCRIPTION The nuclear unit is located in Callaway County, Missouri, approximately 80 miles west of the St. Louis metropolitan area. The nearest population center is Jefferson City, 25 miles west-southwest of the plant site. The station is a 1,171 MWe (net design electrical rating) pressurized water reactor with supporting facilities.
Westinghouse Electric Company designed the nuclear steam supply system (NSSS). The NSSS consists of a pressurized water reactor with four independent primary coolant loops, each of which contains a reactor coolant pump and a steam generator. An electrically heated pressurizer and connecting piping complete the system. The NSSS is rated at a thermal power level of 3,579 MWt (3,565 MWt reactor core plus 14 MWt for reactor coolant pumps), with a corresponding turbine-generator gross output of 1,284 MWe. The system is housed within a containment structure, a pre-stressed, post-tensioned concrete structure with cylindrical wall, a hemispherical dome, and a flat foundation slab.
The wall and dome form a pre-stressed post-tensioned system. The inside surface of the structure is covered with a carbon steel liner, providing a leak tight membrane.
A power conversion system converts heat produced in the reactor to electrical energy. This system converts the thermal energy of the steam into mechanical shaft power and then into electrical energy. The turbine-generator is a tandem compound, six-flow, four element, 1800-rpm unit. The unit consists of one high pressure and three low-pressure turbine elements driving a directly coupled generator. The turbine is operated in a closed feedwater cycle that condenses the steam; the feedwater is returned to the steam generators. Heat rejected in the main condensers is removed by the circulating water system.
The circulating water system supplies cooling water to the main condenser, condensing the steam exhausted from the turbine. Cooling for the condenser circulating water system is supplied by a large natural draft cooling tower.
Makeup water for the cooling tower is drawn from the Missouri River.
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section1, Page 3 of 10 TLG Services, LLC 1.3 REGULATORY GUIDANCE The Nuclear Regulatory Commission (NRC or Commission) provided initial decommissioning requirements in its rule "General Requirements for Decommissioning Nuclear Facilities," issued in June 1988.[2] This rule set forth financial criteria for decommissioning licensed nuclear power facilities. The regulation addressed decommissioning planning needs, timing, funding methods, and environmental review requirements. The intent of the rule was to ensure that decommissioning would be accomplished in a safe and timely manner and that adequate funds would be available for this purpose.
Subsequent to the rule, the NRC issued Regulatory Guide 1.159, Assuring the Availability of Funds for Decommissioning Nuclear Reactors,[3] which provided additional guidance to the licensees of nuclear facilities on the financial methods acceptable to the NRC staff for complying with the requirements of the rule. The regulatory guide addressed the funding requirements and provided guidance on the content and form of the financial assurance mechanisms indicated in the rule.
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 plants systems, structures and facilities are removed or decontaminated to levels that permit the site to be released for unrestricted use shortly after the cessation of plant operations. The rule also placed limits on the time allowed to complete the decommissioning process. For SAFSTOR, the process is restricted in overall duration to 60 years, unless it can be shown that a longer duration is necessary to protect public health and safety. The guidelines for ENTOMB are similar, providing the NRC with both sufficient leverage and flexibility to ensure that these deferred options are only used in situations where it is reasonable and consistent with the definition of decommissioning. At the conclusion of a 60-year dormancy period (or longer for ENTOMB if the NRC approves such a case), the site would still require significant remediation to meet the unrestricted release limits for license termination.
The ENTOMB alternative has not been viewed as a viable option for power reactors due to the significant time required to isolate the long-lived radionuclides for decay to permissible levels. However, with rulemaking permitting the controlled release of a site,[4] the NRC has re-evaluated this alternative. The resulting feasibility study, based upon an assessment by Pacific Northwest National Laboratory, concluded that the method did have conditional merit for some, if not most reactors. However, the staff also found that additional rulemaking would be needed before this option could be treated as a generic alternative. The NRC had considered rulemaking to alter the 60-year time for
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section1, Page 4 of 10 TLG Services, LLC completing decommissioning and to clarify the use of engineered barriers for reactor entombments.[5]
The NRCs staff has recommended that rulemaking be deferred, based upon several factors, e.g., no licensee has committed to pursuing the entombment option, and the NRCs current priorities, at least until after the additional research studies are complete. The NRC concurred with the staffs recommendation. In a draft regulatory basis document published in March 2017 in support of rulemaking that would amend NRC regulations concerning nuclear plant decommissioning, the NRC staff proposes removing any discussion of the ENTOMB option from existing guidance documents since the method is not deemed practically feasible.
In 1996, the NRC published revisions to the general requirements for decommissioning nuclear power plants.[6] When the decommissioning regulations were adopted in 1988, it was assumed that the majority of licensees would decommission at the end of the facilitys 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).
In 2011, the NRC issued regulations to improve decommissioning planning and thereby reduce the likelihood that any current operating facility will become a legacy site.[7] The regulations require licensees to report additional details in
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section1, Page 5 of 10 TLG Services, LLC their decommissioning cost estimate including a decommissioning estimate for the ISFSI. This estimate is provided in Appendix G.
1.3.1 High-Level Radioactive Waste Management Congress passed the Nuclear Waste Policy Act[8] (NWPA) in 1982, assigning the federal governments long-standing responsibility for disposal of the spent nuclear fuel created by the commercial nuclear generating plants to the U.S. Department of Energy (DOE). The DOE was to begin accepting spent fuel by January 31, 1998; however, to date no progress in the removal of spent fuel from commercial generating sites has been made.
Today, the country is at an impasse on high-level waste disposal, even with the License Application for a geologic repository submitted by the DOE to the NRC in 2008. The Obama administration has cut the budget for the repository program while promising to conduct a comprehensive review of policies for managing the back end of the nuclear fuel cycle and make recommendations for a new plan. Towards this goal, the Obama administration appointed a Blue Ribbon Commission on Americas Nuclear Future (Blue Ribbon Commission) to make recommendations for a new plan for nuclear waste disposal. The Blue Ribbon Commissions charter includes a requirement that it consider
[o]ptions for safe storage of used nuclear fuel while final disposition pathways are selected and deployed.[9]
On January 26, 2012, the Blue Ribbon Commission issued its Report to the Secretary of Energy containing a number of recommendations on nuclear waste disposal. Two of the recommendations that may impact decommissioning planning are:
[T]he United States [should] establish a program that leads to the timely development of one or more consolidated storage facilities
[T]he United States should undertake an integrated nuclear waste management program that leads to the timely development of one or more permanent deep geological facilities for the safe disposal of spent fuel and high-level nuclear waste.[10]
In January 2013, the DOE issued the Strategy for the Management and Disposal of Used Nuclear Fuel and High-Level Radioactive Waste, in response to the recommendations made by the Blue Ribbon Commission
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section1, Page 6 of 10 TLG Services, LLC and as a framework for moving toward a sustainable program to deploy an integrated system capable of transporting, storing, and disposing of used nuclear fuel...[11]
With the appropriate authorizations from Congress, the Administration currently plans to implement a program over the next 10 years that:
Sites, designs and licenses, constructs and begins operations of a pilot interim storage facility by 2021 with an initial focus on accepting used nuclear fuel from shut-down reactor sites; Advances toward the siting and licensing of a larger interim storage facility to be available by 2025 that will have sufficient capacity to provide flexibility in the waste management system and allows for acceptance of enough used nuclear fuel to reduce expected government liabilities; and Makes demonstrable progress on the siting and characterization of repository sites to facilitate the availability of a geologic repository by 2048.
The NRCs review of DOEs license application to construct a geologic repository at Yucca Mountain was suspended in 2011 when the Obama administration significantly reduced the budget for completing that work.
However, the US Court of Appeals for the District of Columbia Circuit issued a writ of mandamus (in August 2013)[12] ordering NRC to comply with federal law and resume its review of DOE's Yucca Mountain repository license application, to the extent allowed by previously appropriated funding for the review. That review is now complete with the publication of the five-volume safety evaluation report. A supplement to DOEs environmental impact statement and adjudicatory hearing on the contentions filed by interested parties must be completed before a licensing decision can be made. Although the DOE proposed it would start fuel acceptance in 2025, no progress has been made in the repository program since DOEs 2013 strategy was issued except for the completion of the Yucca Mountain safety evaluation report.
Holtec International submitted a license application to the NRC on March 30, 2017 for a consolidated interim spent fuel storage facility in southeast New Mexico called HI-STORE CISF (Consolidated Interim Storage Facility) under the provisions of 10 CFR Part 72. In May 2023, the NRC issued a license to Holtec to construct and operate a facility to receive, possess, store, and transfer spent nuclear fuel at the HI-STORE CISF.
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section1, Page 7 of 10 TLG Services, LLC Waste Control Specialists (WCS) submitted an application to the NRC on April 28, 2016, to construct and operate a Consolidated Interim Storage Facility (CISF) at its West Texas facility. On April 18, 2017, WCS requested that the NRC temporarily suspend all safety and environmental review activities, as well as public participation activities associated with WCSs license application. In March 2018, WCS and Orano USA, announced their intent to form a joint venture to license the facility. The joint venture, named Interim Storage Partners (ISP),
requested that the NRC resume its review of the original CISF license application. Subsequently, in September, 2021, NRC issued a license to ISP for its WCS CISF to construct and operate the facility for spent nuclear fuel and Greater than Class C waste (GTCC) storage. However, the facility is not yet operational.
Completion of the decommissioning process is dependent upon the DOEs ability to remove spent fuel from the site in a timely manner. In June 2011, Ameren Services and the DOE reached an agreement on a settlement. The terms include payment to Ameren Services for spent fuel storage and related costs through 2010, and thereafter, annual payment of such costs after they are incurred.
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 DOE, pursuant to 10 CFR Part 50.54(bb).[13] The post-shutdown costs incurred to satisfy this requirement include the isolation and continued operation of the spent fuel pool and the ISFSI during the five and one-half years following the cessation of plant operations.
At shutdown, the spent fuel pool is expected to contain freshly discharged assemblies (from the most recent refueling cycles) as well as the final reactor core. During the next five and one-half years, the assemblies are packaged into Transportation, Aging, and Disposal canisters (TADs) for transfer to the DOE. It is assumed that this period provides the necessary cooling for the final core to meet the transportation system requirements for decay heat.
Costs are included within the decommissioning estimates for offloading the pool. These costs include the loading of DOE-provided TADs and the associated campaign costs to load the canisters into the DOE-provided transport vehicle.
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section1, Page 8 of 10 TLG Services, LLC Removal of the fuel from the ISFSI is expected to be fully reimbursable and therefore not addressed in this study. However, the eventual decommissioning of the ISFSI is included.
The estimates described in this analysis were developed with the assumption that the DOE would give priority to removing spent fuel from shutdown sites. The estimates further assume that the spent fuel would be removed from the Callaway site within five and one-half years of the cessation of plant operations (i.e., five and one-half years would provide sufficient cooling time for the spent fuel to meet DOE transportation requirements).
1.3.2 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,[14] and its Amendments of 1985,[15]
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 Texas Compact disposal facility is assumed operational and waste is being accepted from generators within the Compact by the operator, Waste Control Specialists (WCS). The facility, located in Andrews, Texas, is also assumed able to accept limited quantities of non-Compact waste.
Disposition of the various waste streams produced by the decommissioning process considered all options and services currently available to Ameren Services. The majority of the low-level radioactive waste designated for controlled disposal (Class A[16] ) can be sent to EnergySolutions facility in Clive, Utah. Therefore, disposal costs for Class A waste were based upon Ameren Services agreement with EnergySolutions. This facility is not licensed to receive the higher activity portion (Classes B and C) of the decommissioning waste stream.
The WCS facility is able to receive the Class B and C waste. As such, for this analysis, Class B and C waste was assumed to be shipped to the WCS facility for disposal. Disposal costs were based upon Ameren Services current agreement with WCS.
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section1, Page 9 of 10 TLG Services, LLC The dismantling of the components residing closest to the reactor core generates radioactive waste that may be considered unsuitable for shallow-land disposal (i.e., low-level radioactive waste with concentrations of radionuclides that exceed the limits established by the NRC for Class C radioactive waste (GTCC)). The Low-Level Radioactive Waste Policy Amendments Act of 1985 assigned the federal government the responsibility for the disposal of this material. The Act also stated that the beneficiaries of the activities resulting in the generation of such radioactive waste bear all reasonable costs of disposing of such waste.
The DOE issued its Final Environmental Impact Statement for the disposal of GTCC on January 2016.[17] The study evaluated the potential environmental impacts associated with constructing and operating a new facility or using an existing facility, disposal methods, and locations. DOE is awaiting congressional action on the report and its recommendations.
At this time, the federal government has not identified a specific cost for disposing of GTCC or a schedule for acceptance.
For purposes of this analysis only, the GTCC radioactive waste is assumed to be packaged and disposed of in a similar manner as high-level waste and at a cost equivalent to that envisioned for the spent fuel. The GTCC is packaged in the same canisters used for spent fuel and shipped to a DOE facility.
A significant portion of the waste material generated during decommissioning may only be potentially contaminated by radioactive materials. This material can be analyzed on site or shipped off site to licensed facilities for further analysis, for processing and/or for conditioning/recovery. Reduction in the volume of low-level radioactive waste requiring disposal in a licensed low-level radioactive waste disposal facility can be accomplished through a variety of methods, including analyses and surveys or decontamination to eliminate the portion of waste that does not require disposal as radioactive waste, compaction, incineration or metal melt. The estimates for the base case scenarios reflect the savings from waste recovery/volume reduction.
1.3.3 Radiological Criteria for License Termination In 1997, the NRC published Subpart E, Radiological Criteria for License Termination,[18] 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
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section1, Page 10 of 10 TLG Services, LLC would not receive a Total Effective Dose Equivalent (TEDE) in excess of 25 millirem per year, and provided that residual radioactivity has been reduced to levels that are As Low As Reasonably Achievable (ALARA).
The decommissioning estimates assume that the Callaway site will be remediated to a residual level consistent with the NRC-prescribed level.
It should be noted that the NRC and the Environmental Protection Agency (EPA) differ on the amount of residual radioactivity considered acceptable in site remediation. The EPA has two limits that apply to radioactive materials. An EPA limit of 15 millirem per year is derived from criteria established by the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA or Superfund).[19] An additional and separate limit of 4 millirem per year, as defined in 40 CFR
§141.16, is applied to drinking water.[20]
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)[21] 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.

- 2. DECOMMISSIONING ALTERNATIVES Two decommissioning alternatives, DECON and SAFSTOR, were evaluated for the Callaway Energy Center. Although the alternatives differ with respect to technique, process, cost, and schedule, they attain the same result: the ultimate release of the site for unrestricted use. The scenarios selected are representative of alternatives currently available to the owner and are defined as follows:
- 1. The first scenario assumes that the nuclear unit is promptly decommissioned (DECON alternative) upon the expiration of the current operating license in 2044. Following the permanent cessation of operations, and over the first five and one-half years, the spent fuel is transferred directly from the wet storage pool to the DOE (the fuel stored on the ISFSI is also removed from the site during this time period). Concurrently, the majority of the plant components, including the nuclear NSSS components, are removed. Once the spent fuel stored in the fuel pool has been transferred off-site, the remaining portions of the power block are decommissioned and the surrounding site remediated. Following the termination of the operating license, all remaining site structures are dismantled.
- 2. In the second scenario, the nuclear unit is placed into safe storage (SAFSTOR alternative) upon the expiration of the current operating license in 2044. As with the first scenario, the spent fuel is removed from the site (transferred to the DOE) during the first five and one-half years following the permanent cessation of operations. The facility is then placed into safe storage (with non-essential systems de-energized and buildings secured).
The start of decontamination and dismantling activities is deferred to the maximum extent (approximately 50 years from the cessation of operations) such that the license is terminated within the required 60-year period following permanent cessation of operations.
The following sections describe the basic activities associated with each alternative.
Although detailed procedures for each activity identified are not provided, and the actual sequence of work may vary, the activity descriptions provide a basis not only for estimating but also for the expected scope of work, i.e., engineering and planning at the time of decommissioning.
In addition to the two decommissioning alternatives, two disposal options were assessed: recycling and direct disposal. Recycling is presented as the base option and considers the off-site processing of plant equipment and commodities with low levels of radiological contamination and/or material suspected to be contaminated for
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 2, Page 2 of 12 TLG Services, LLC volume reduction prior to disposal. The direct disposal option assumes that all contaminated and suspect material is packaged at the site for disposal at a regulated disposal facility. The scenarios are summarized as follows.
Alternative Low-Level Radioactive Waste Options Cost Summaries and/or Detailed Estimates DECON Recycling Sections 3, 6, Appendix C Direct Disposal Appendix E SAFSTOR Recycling Sections 3, 6, Appendix D Direct Disposal Appendix F 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 estimates developed for Callaway are also divided into phases or periods; however, demarcation of the phases is based upon major milestones within the project or significant changes in the projected expenditures.
2.1 DECON The DECON alternative, as defined by the NRC, is "the alternative in which the equipment, structures, and portions of a facility and site containing radioactive contaminants are removed or decontaminated to a level that permits the property to be released for unrestricted use shortly after cessation of operations."
This study does not address the cost to dispose of the spent fuel residing at the site; such costs are funded through a surcharge on electrical generation. The study also assumes that the costs incurred with the removal of the spent fuel from the ISFSI are fully reimbursable, and are also not included.
2.1.1 Period 1 - Preparations In anticipation of the cessation of plant operations, detailed preparations are undertaken to provide a smooth transition from plant operations to site decommissioning. Through implementation of a staffing transition
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 2, Page 3 of 12 TLG Services, LLC plan, the organization required to manage the intended decommissioning activities is assembled from available plant staff and outside resources.
Preparations include the planning for permanent defueling of the reactor, revision of technical specifications applicable to the operating conditions and requirements, a characterization of the facility and major components, and the development of the PSDAR.
Engineering and Planning The PSDAR, required prior to or within two years of permanent cessation of operations, provides a description of the licensees planned decommissioning activities, a timetable, and the associated financial requirements of the intended decommissioning program. Upon receipt of the PSDAR, the NRC will make the document available to the public for comment in a local hearing to be held in the vicinity of the reactor site.
Ninety days following submittal and NRC receipt of the PSDAR, the licensee may begin to perform major decommissioning activities under a modified 10 CFR §50.59 procedure, i.e., without specific NRC approval.
Major activities are defined as any activity that results in permanent removal of major radioactive components, permanently modifies the structure of the containment, or results in dismantling components (for shipment) containing GTCC, as defined by 10 CFR §61. Major components are further defined as comprising the reactor vessel and internals, large bore reactor coolant system piping, and other large components that are radioactive. The NRC includes the following additional criteria for use of the §50.59 process in decommissioning. The proposed activity must not:
foreclose release of the site for possible unrestricted use, significantly increase decommissioning costs, cause any significant environmental impact, or violate the terms of the licensees existing license.
Existing operational technical specifications are reviewed and modified to reflect plant conditions and the safety concerns associated with permanent cessation of operations. The environmental impact associated with the planned decommissioning activities is also considered. Typically, a licensee will not be allowed to proceed if the consequences of a particular decommissioning activity are greater than that bounded by previously evaluated environmental assessments or impact statements. In this instance, the licensee would have to submit a license amendment for the specific activity and update the environmental report.
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 2, Page 4 of 12 TLG Services, LLC The decommissioning program outlined in the PSDAR will be designed to accomplish the required tasks within the ALARA guidelines (as defined in 10 CFR §20) for protection of personnel from exposure to radiation hazards. It will also address the continued protection of the health and safety of the public and the environment during the dismantling activity.
Consequently, with the development of the
- PSDAR, activity specifications, cost-benefit and safety analyses, work packages and procedures, would be assembled to support the proposed decontamination and dismantling activities.
Site Preparations Following final plant shutdown, and in preparation for actual decommissioning activities, the following activities are initiated:
Characterization of the site and surrounding environs. This includes radiation surveys of work areas, major components (including the reactor vessel and its internals), internal piping, and primary shield cores.
Isolation of the spent fuel storage pool and fuel handling systems, such that decommissioning operations can commence on the balance of the plant. The pool will remain operational for approximately five and one-half years following the cessation of operations before the inventory resident at shutdown can be transferred to the ISFSI.
Specification of transport and disposal requirements for activated materials and/or hazardous materials, including shielding and waste stabilization.
Development of procedures for occupational exposure control, control and release of liquid and gaseous effluent, processing of radwaste (including dry-active waste, resins, filter media, metallic and non-metallic components generated in decommissioning), site security and emergency programs, and industrial safety.
2.1.2 Period 2 - Decommissioning Operations This period includes the physical decommissioning activities associated with the removal and disposal of contaminated and activated components and structures, including the successful termination of the 10 CFR §50 operating license. Significant decommissioning activities in this phase include:
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 2, Page 5 of 12 TLG Services, LLC 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 containment structure 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.
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 2, Page 6 of 12 TLG Services, LLC Removal of the activated portions of the concrete biological shield and accessible contaminated concrete surfaces. If dictated by the steam generator and pressurizer removal scenarios, those portions of the associated cubicles necessary for access and component extraction are removed.
Removal of the steam generators and pressurizer for material recovery and controlled disposal. The steam generators will be moved to an on-site processing center, the steam domes removed and the internal components segregated for recycling. The lower shell and tube bundle will be packaged for direct disposal. These components can serve as their own burial containers provided that all penetrations are properly sealed and the internal contaminants are stabilized, e.g., with grout.
Steel shielding will be added, as necessary, to those external areas of the package to meet transportation limits and regulations. The pressurizer is disposed of intact.
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 or its equivalent, the plan must include: a site characterization, description of the remaining dismantling activities, plans for site remediation, procedures for the final radiation survey, designation of the end use of the site, an updated cost estimate to complete the decommissioning, and any associated environmental concerns. The NRC will notice the receipt of the plan, make the plan available for public comment, and schedule a local hearing. LTP approval will be subject to any conditions and limitations as deemed appropriate by the Commission.
The licensee may then commence with the final remediation of site facilities and services, including:
Removal of remaining plant systems and associated components as they become nonessential to the decommissioning program or worker health and safety (e.g., waste collection and treatment systems, electrical power and ventilation systems).
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 containment structure.
Remediation and removal of the contaminated equipment and material from the fuel 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
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 2, Page 7 of 12 TLG Services, LLC 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).[22] This document incorporates the statistical approaches to survey design and data 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 for unrestricted use).
The NRC will amend the operating licenses 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 property is suitable for release.
2.1.3 Period 3 - Site Restoration Following completion of decommissioning operations, site restoration activities will begin. Efficient removal of the contaminated materials and verification that residual radionuclide concentrations are below the NRC limits will result in substantial damage to many of the structures.
Although performed in a controlled, safe manner, blasting, coring,
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 2, Page 8 of 12 TLG Services, LLC drilling, scarification (surface removal), and the other decontamination activities will substantially degrade power block structures including the reactor, auxiliary, fuel, and radwaste buildings. Under certain circumstances, verifying that subsurface radionuclide concentrations meet NRC site release requirements will require removal of grade slabs and lower floors, potentially weakening footings and structural supports.
This removal activity will be necessary for those facilities and plant areas where historical records, when available, indicate the potential for radionuclides having been present in the soil, where system failures have been recorded, or where it is required to confirm that subsurface process and drain lines were not breached over the operating life of the station.
It is not currently anticipated that these structures would be repaired and preserved after the radiological contamination is removed. The cost to dismantle site structures, once remediation is complete, with a work force already mobilized on site is more efficient than if the process is deferred.
This cost study presumes that non-essential structures and site facilities are dismantled as a continuation of the decommissioning activity.
Foundations and exterior walls are removed to a nominal depth of three feet below grade. The three-foot depth allows for the placement of gravel for drainage, as well as topsoil, so that vegetation can be established for erosion control. Site areas affected by the dismantling activities are restored and the plant area graded as required to prevent ponding and inhibit the refloating of subsurface materials.
Non-contaminated concrete rubble produced by demolition activities is processed to remove reinforcing steel and miscellaneous embedments.
The processed material is then used on site to backfill foundation voids.
Excess non-contaminated materials are trucked to an off-site area for disposal as construction debris.
2.2 SAFSTOR The NRC defines SAFSTOR as "the alternative in which the nuclear facility is placed and maintained in a condition that allows the nuclear facility to be safely stored and subsequently decontaminated (deferred decontamination) to levels that permit release for unrestricted use." The facility is left intact (during the dormancy period), with structures maintained in a sound condition. Systems that are not required to support the spent fuel 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
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 2, Page 9 of 12 TLG Services, LLC performed. Access to contaminated areas is secured to provide controlled access for inspection and maintenance.
The engineering and planning requirements are similar to those for the DECON alternative, although a shorter period is expected for these activities due to the more limited work scope. Site preparations are also similar to those for the DECON alternative. However, with the exception of the required radiation surveys and site characterizations, the mobilization and preparation of site facilities is less extensive.
2.2.1 Period 1 - Preparations Preparations for long-term storage include the planning for permanent defueling of the reactor, revision of technical specifications appropriate to the operating conditions and requirements, a characterization of the facility and major components, and the development of the PSDAR.
The process of placing the plant in safe-storage includes, but is not limited to, the following activities:
Isolation of the spent fuel storage services and fuel handling systems so that safe-storage operations may commence on the balance of the plant. This activity may be carried out by plant personnel in accordance with existing operating technical specifications. Activities are scheduled around the fuel handling systems to the greatest extent possible.
Transfer of all spent fuel from the storage pool and the ISFSI to the DOE by the end of the minimum required cooling period.
Draining and de-energizing of the non-contaminated systems not required to support continued site operations or maintenance.
Disposing of contaminated filter elements and resin beds not required for processing wastes from layup activities for future operations.
Draining of the reactor vessel, with the internals left in place and the vessel head secured.
Draining and de-energizing non-essential, contaminated systems with decontamination as required for future maintenance and inspection.
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.
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 2, Page 10 of 12 TLG Services, LLC 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.
2.2.2 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 alternative. Dormancy activities include a 24-hour security force, preventive and corrective maintenance on security systems, area lighting, general building maintenance, heating and ventilation of buildings, routine radiological inspections of contaminated structures, maintenance of structural integrity, and a site environmental and radiation monitoring program. Resident maintenance personnel perform equipment maintenance, inspection activities, routine services to maintain safe conditions, adequate lighting, heating, and ventilation, and periodic preventive maintenance on essential site services.
An environmental surveillance program is carried out during the dormancy period to ensure that releases of radioactive material to the environment are prevented and/or detected and controlled. Appropriate emergency procedures are established and initiated for potential releases that exceed prescribed limits. The environmental surveillance program constitutes an abbreviated version of the program in effect during normal plant operations.
Security during the dormancy period is conducted primarily to prevent unauthorized entry and to protect the public from the consequences of its own actions. The security fence, sensors, alarms, and other surveillance equipment provide security. Fire and radiation alarms are also monitored and maintained.
Consistent with the DECON scenario, the spent fuel storage pool is emptied within five and one-half years of the cessation of operations. The
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 2, Page 11 of 12 TLG Services, LLC pool is secured for storage and decommissioned along with the power block structures in Period 4.
After a period of storage (such that license termination is accomplished within 60 years of final shutdown), it is required that the licensee submit an application to terminate the license, along with an LTP (described in Section 2.1.2), thereby initiating the third phase.
2.2.3 Periods 3 and 4 - Delayed Decommissioning Prior to the commencement of decommissioning operations, preparations are undertaken to reactivate site services and prepare for decommissioning. Preparations include engineering and planning, a detailed site characterization, and the assembly of a decommissioning management organization. Final planning for activities and the writing of activity specifications and detailed procedures are also initiated at this time.
Much of the work in developing a termination plan is relevant to the development of the detailed engineering plans and procedures. The activities associated with this phase and the follow-on decontamination and dismantling processes are detailed in Sections 2.1.1 and 2.1.2. The primary difference between the sequences anticipated for the DECON and this deferred scenario is the absence, in the latter, of any constraint on the availability of the fuel storage facilities for decommissioning.
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 sixty years of plant operation, no plant process system identified as being contaminated upon final shutdown will become releasable due to the decay period alone, i.e., there is no significant reduction in the waste generated from the decommissioning activities. However, due to the lower activity levels, a greater percentage of the waste volume can be designated for off-site processing and recovery.
The delay in decommissioning also yields lower working area radiation levels. As such, the estimate for this delayed scenario incorporates reduced ALARA controls for the SAFSTOR's lower occupational exposure potential.
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 2, Page 12 of 12 TLG Services, LLC 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, 59Ni, and 63Ni. Therefore, the dismantling procedures described for the DECON alternative 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 (152Eu and 154Eu).
Decontamination will require controlled removal and disposal. It is assumed that radioactive corrosion products on inner surfaces of piping and components will not have decayed to levels that will permit unrestricted use or allow conventional removal. These systems and components will be surveyed as they are removed and disposed of in accordance with the existing radioactive release criteria.
2.2.4 Period 5 - Site Restoration Following completion of decommissioning operations, site-restoration activities can begin.
Dismantling, as a
continuation of the decommissioning process, is clearly the most appropriate and cost-effective option, as described in Section 2.1.3. The basis for the dismantling cost in this scenario is consistent with that described for DECON, presuming the removal of structures and site facilities to a nominal depth of three feet below grade and the limited restoration of the site.
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 1 of 34 TLG Services, LLC
- 3. COST ESTIMATE The cost estimates prepared for decommissioning Callaway consider the unique features of the site, including the NSSS, power generation systems, support services, site buildings, and ancillary facilities. The basis of the estimates, including the sources of information relied upon, the estimating methodology employed, site-specific considerations, and other pertinent assumptions, is described in this section.
3.1 BASIS OF ESTIMATE The current estimates were developed using the site-specific, technical information relied upon in the decommissioning analysis prepared in 2020. This information was reviewed for the current analysis and updated as deemed appropriate. The site-specific considerations and assumptions used in the previous evaluation were also revisited. Modifications were incorporated where new information was available or experience from ongoing decommissioning programs provided viable alternatives or improved processes.
3.2 METHODOLOGY The methodology used to develop the estimates follows the basic approach originally presented in the AIF/NESP-036 study report, "Guidelines for Producing Commercial Nuclear Power Plant Decommissioning Cost Estimates,"[23] and the DOE "Decommissioning Handbook."[24] 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 with RSMeans Data," by Gordian.[25]
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.
Regulatory Guide 1.184 [26] Revision 1, issued in October 2013, describes the methods and procedures that are acceptable to the NRC staff for implementing
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 2 of 34 TLG Services, LLC the requirements that relate to the initial activities and the major phases of the decommissioning process. The costs and schedules presented in this analysis follow the general guidance and sequence in the regulations. The format and content of the estimates is also consistent with the recommendations of Regulatory Guide 1.202,[27] issued February 2005.
This analysis reflects lessons learned from TLGs 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 Rancho Seco, Trojan, Yankee Rowe, Big Rock Point, Maine Yankee, Humboldt Bay-3, Oyster Creek, Connecticut Yankee, Crystal River, Vermont Yankee, Fort Calhoun and Pilgrim, and Indian Point 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 person-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
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 3 of 34 TLG Services, LLC 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 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 TLGs 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[28] 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
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 4 of 34 TLG Services, LLC and inflation in the cost of decommissioning over the remaining operating life of the station.
Contingency funds are an integral part of the total cost to complete the decommissioning process. Exclusion of this component puts at risk a successful completion of the intended tasks and, potentially, subsequent related activities. For this study, TLG examined the major activity-related problems (decontamination, segmentation, equipment handling, packaging, transport, and waste disposal) that necessitate a contingency.
Individual activity contingencies ranged from 10% to 75%, depending on the degree of difficulty judged to be appropriate from TLGs actual decommissioning experience. The contingency values used in this study are as follows:
Decontamination 50%
Contaminated Component Removal 25%
Contaminated Component Packaging 10%
Contaminated Component Transport 15%
Low-Level Radioactive Waste Disposal 25%
Low-Level Radioactive Waste Processing 15%
Reactor Segmentation 75%
NSSS Component Removal 25%
Reactor Waste Packaging 25%
Reactor Waste Transport 25%
Reactor Vessel Component Disposal 50%
GTCC Disposal 15%
Staffing 15%
Spent Fuel Management 15%
Non-Radioactive Component Removal 15%
Heavy Equipment and Tooling 15%
Supplies 25%
Engineering 15%
Energy 15%
Insurance and Fees 10%
Characterization and Termination Surveys 30%
Operations and Maintenance Expense 15%
Construction 15%
Property Taxes 10%
ISFSI Decommissioning 25%
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 5 of 34 TLG Services, LLC The contingency values are applied to the appropriate components of the estimates on a line item basis. A composite value is then reported at the end of each detailed estimate (as provided in Appendix C, D, E and F). A contingency of 25% is applied to the subtotal of the ISFSI decommissioning costs, as shown in Appendix G Table G-2 for ISFSI 72.30 decommissioning and license termination activities.
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.
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 6 of 34 TLG Services, LLC 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.
However this cost study does not add any additional costs to the estimate for financial risk, since there is insufficient historical data from which to project future liabilities. Consequently, the areas of uncertainty or risk are revisited periodically and addressed through repeated revisions or updates of the estimates.
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 estimates to decommission Callaway. Ultimate disposition of the spent fuel is within the province of the DOEs Waste Management System, as defined by the Nuclear Waste Policy Act. Any delay in the transfer of spent fuel may increase the on-site management costs. As such, the disposal cost was being financed by a 1 mill/kWhr surcharge on nuclear generated energy delivered to customers, the fee being paid into the DOEs waste fund during operations. The D.C. Circuit ruling on November 19, 2013, ordered the DOE to submit a proposal to Congress to suspend the Nuclear Waste Fund fee until such time as either the Secretary chooses to comply with the Act as it is currently written, or until Congress enacts an alternative waste management plan.
The fee was reduced to 0.0 mill/kWh as of May 16, 2014. The fee is expected to be reinstated in the future.
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 estimates, as described below.
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 7 of 34 TLG Services, LLC For estimating purposes, Ameren Services has assumed that all spent fuel will be transferred to the DOE within five and one-half years after shutdown.
This will allow Ameren Services to proceed with decommissioning (or safe-storage) operations in the shortest time possible. A delay in the start of fuel pickup, or a decrease in the spent fuel acceptance rate, will correspondingly prolong the transfer process and result in the fuel remaining at the Callaway site longer.
It is assumed that the five and one-half years provides the necessary cooling period for the final core to meet DOEs transport system requirements for decay heat. Once the pool is emptied, the spent fuel storage and handling facilities are available for decommissioning.
Operation and maintenance costs for the spent fuel pool are included within the estimate as well as the costs to transfer the spent fuel from the pool to the DOE.
Storage Canister Design A vertical underground dry storage system is used as a cost basis. The system consists of Holtec HI-STORM UMAX technology transportable Multi-Purpose Canisters (MPCs) stored within an underground metal and concrete structure, collectively known as Vertical Ventilated Modules (VVMs). A canister capacity of 37 pressurized water reactor fuel assemblies was assumed. All canisters are assumed to be in place at the time of decommissioning.
Canister Loading and Transfer The estimates include the cost for the labor and equipment to load and transfer to the DOE the spent fuel assemblies projected to reside in the pool at the cessation of plant operations. Costs for transfer of spent fuel from the ISFSI to the DOE are not included in this estimate. In addition, any capital cost associated with the dry storage system (including cask purchases) is not included in the estimates.
Operations and Maintenance The estimates include the cost of operating and maintaining the spent fuel pool for approximately five and one half years after the cessation of operations.
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 8 of 34 TLG Services, LLC ISFSI Decommissioning In accordance with 10 CFR §72.30, licensees must have a proposed decommissioning plan for the ISFSI site and facilities that includes a cost estimate for the plan. The plan needs to contain sufficient information on the proposed practices and procedures for the decontamination of the ISFSI and for the disposal of residual radioactive materials after the spent fuel has been removed.
For purposes of this study only, the decommissioning cost for the ISFSI was included in the DECON and SAFSTOR estimates.
The decommissioning estimate is based on the conservative premise that a small percentage of the VVMs would contain very low levels of neutron-induced residual radioactivity that would necessitate remediation at the time of decommissioning. As an allowance, 6 of the 48 VVMs are assumed to be affected, i.e., contain residual radioactivity. The allowance quantity is based upon the number of MPCs required for the final core off-load (i.e.,
193 offloaded assemblies, 37 assemblies per MPC) which results in a total of 6 VVMs that contain residual radioactivity.
No contamination or activation of the balance of the ISFSI structures are assumed. It would be expected that this assumption would be confirmed as a result of good radiological practice of surveying potentially impacted areas after each spent fuel transfer campaign. As such, only verification surveys are included for the ISFSI in the decommissioning estimate. The estimate is limited to costs necessary to terminate the ISFSIs NRC license and meet the §20.1402 criteria for unrestricted use.
In accordance with the specific requirements of 10 CFR §72.30 for the ISFSI work scope, the cost estimate for decommissioning the ISFSI reflects: 1) the cost of an independent contractor performing the decommissioning activities; 2) an adequate contingency factor; and 3) the cost of meeting the criteria for unrestricted use.
GTCC The dismantling of the reactor internals is expected to generate radioactive waste considered unsuitable for shallow land disposal (i.e.,
low-level radioactive waste with concentrations of radionuclides that exceed the limits established by the NRC for Class C radioactive waste (GTCC)). The Low-Level Radioactive Waste Policy Amendments Act of 1985 assigned the federal government the responsibility for the disposal of this material. The Act also stated that the beneficiaries of the activities
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 9 of 34 TLG Services, LLC resulting in the generation of such radioactive waste bear all reasonable costs of disposing of such waste. Although the DOE is responsible for disposing of GTCC waste, any costs for that service have not been determined. For purposes of this estimate, the GTCC radioactive waste 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 number of canisters required and the packaged volume for GTCC was based upon experience at Maine Yankee (e.g., the payload constraints as identified in the canisters certificate of compliance).
For purposes of this study, GTCC is packaged into five transportable storage containers. It will be disposed of as it is generated during reactor vessel segmentation operations, and shipped to the DOE.
3.4.2 Reactor Vessel and Internal Components The reactor pressure vessel and internal components are segmented for disposal in shielded, reusable transportation casks. Segmentation is performed in the refueling canal, where a turntable and remote cutter are installed. The vessel is segmented in place, using a mast-mounted cutter supported off the lower head and directed from a shielded work platform installed overhead in the reactor cavity.
Transportation cask specifications and transportation regulations dictate the segmentation and packaging methodology.
Intact disposal of reactor vessel shells has been successfully demonstrated at several of the sites currently being decommissioned. Access to navigable waterways has allowed these large packages to be transported to the Barnwell, South Carolina and Hanford, Washington disposal sites 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,
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 10 of 34 TLG Services, LLC 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 Callaway ceases operation. Future viability of this option will depend upon the ultimate location of the disposal site, as well as the disposal site licensees 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.
3.4.3 Primary System Components In the DECON scenario, the reactor coolant system components are assumed to be decontaminated using chemical agents prior to the start of dismantling operations. This type of decontamination can be expected to have a significant ALARA impact, since in this scenario the removal work is done within the first few years of shutdown. A decontamination factor (average reduction) of 10 is assumed for the process. In the SAFSTOR scenario, radionuclide decay is expected to provide the same benefit and, therefore, a chemical decontamination is not included.
The following discussion deals with the removal and disposition of the steam generators, but the techniques involved are also applicable to other large components, such as heat exchangers, component coolers, and the pressurizer. The steam generators size and weight, as well as their location within the reactor building, will ultimately determine the removal strategy.
A trolley crane is set up for the removal of the generators. It can also be used to move portions of the steam generator cubicle walls and floor slabs from the reactor building to a location where they can be decontaminated and transported to the material handling area. Interferences within the work area, such as grating, piping, and other components are removed to create sufficient laydown space for processing these large components.
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 11 of 34 TLG Services, LLC The generators are rigged for removal, disconnected from the surrounding piping and supports, and maneuvered into the open area where they are lowered onto a dolly. Each generator is rotated into the horizontal position for extraction from the containment and placed onto a multi-wheeled vehicle for transport to an on-site processing and storage area.
The generators are disassembled on-site with the steam dome and lightly contaminated subassemblies designated for off-site recycling. The more highly contaminated tube sheet and tube bundle are packaged for direct disposal. The interior volume is filled with low-density cellular concrete for stabilization of the internal contamination.
Reactor coolant piping is cut from the reactor vessel once the water level in the vessel (used for personnel shielding during dismantling and cutting operations in and around the vessel) is dropped below the nozzle zone. The piping is boxed and transported by shielded van. The reactor coolant pumps and motors are lifted out intact, packaged, and transported for processing and/or disposal.
3.4.4 Retired Components The estimate includes the cost to dispose of four retired steam generators expected to be in storage at the site upon the cessation of plant operations.
The components are processed for disposal in the same manner as described for the installed units.
A retired reactor closure head, with service structure, is also included in the decommissioning waste inventory. The component is currently stored in the steam generator storage facility.
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.
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 12 of 34 TLG Services, LLC 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.[29] 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., 137Cs, 90Sr, or transuranics) has been prevented from reaching levels exceeding those that permit the major reactor components to be shipped under current transportation regulations and disposal requirements.
Transport of the highly activated metal, produced in the segmentation of the reactor vessel and internal components, will be by shielded truck cask.
Cask shipments may exceed 95,000 pounds, including vessel segment(s),
supplementary shielding, cask tie-downs, and tractor-trailer. The maximum level of activity per shipment assumed permissible was based upon the license limits of the available shielded transport casks. The segmentation scheme for the vessel and internal segments is designed to meet these limits.
The transport of large intact components (e.g., large heat exchangers and other oversized components) will be by a combination of truck, rail, and/or multi-wheeled transporter.
Transportation costs for Class A radioactive material requiring controlled disposal are based upon the mileage to the EnergySolutions facility in Clive, Utah. Transportation costs for the higher activity Class B and C radioactive material are based upon the mileage to the WCS facility in Andrews County, Texas. The transportation cost for the GTCC material is assumed to be contained within the disposal cost. Transportation costs for off-site waste processing are based upon the mileage to Oak Ridge,
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 13 of 34 TLG Services, LLC Tennessee. Truck transport costs were developed from published tariffs from Tri-State Motor Transit.[30]
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 the appendices 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.
The cost to dispose of the lowest level waste and 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. Disposal costs for the higher activity waste (Class B and C) were based upon Ameren Services current agreement with WCS for the Andrews County facility.
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 14 of 34 TLG Services, LLC 3.4.8 Site Conditions Following Decommissioning The NRC will terminate the site license when 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 NRCs 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 owners own future plans for the site.
The estimates presented herein include the dismantling of the major structures to three feet below grade level, backfilling and the collapsing of below grade voids, and regrading such that the site upon which the power block and supplemental structures are located is transformed into a grassy plain.
Concrete rubble generated from demolition activities is processed and made available as clean fill for the power block foundations. Additional fill is brought in to cap the power block excavations and to permit seeding for erosion control.
A significant amount of the below grade piping is located around the perimeter of the power block. The estimate includes a cost to excavate this area to an average depth of six feet so as to expose the piping, duct bank, conduit, and any near-surface grounding grid. The overburden is surveyed and stockpiled on site for future use in backfilling the below grade voids.
The existing electrical switchyard and access roads will remain in support of the electrical transmission and distribution system. Site restoration does not include the remediation of the water treatment plants settling basins, if required.
Sludge removed from the sewage treatment plant lagoon was assumed to contain low levels of contamination that would require controlled disposal. As such, 3,600 cubic feet of material from the lagoon was designated for disposition at EnergySolutions facility.
The existing and replacement cooling tower discharge pipes will be left in place and assumed to be flow-filled with suitable material to prevent the pipes from collapsing. The intake line will also be filled.
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 15 of 34 TLG Services, LLC The estimates do not assume the remediation of any significant volume of contaminated soil. This assumption may be affected by continued plant operations and/or future regulatory actions, such as the development of site-specific release criteria.
3.5 ASSUMPTIONS The following are the major assumptions made in the development of the estimates for decommissioning the site.
3.5.1 Estimating Basis Decommissioning costs are reported in the year of projected expenditure; however, the values are provided in 2023 dollars. Costs are not inflated, escalated, or discounted over the periods of performance.
The estimates rely upon the physical plant inventory that was the basis for the 2020 analysis. There were no substantive changes made to the plant inventory (that would impact decommissioning).
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 Ameren Services, as the operator, 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.
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 16 of 34 TLG Services, LLC Personnel costs are based upon average salary information provided by Ameren Services. Overhead costs were also provided by Ameren Services for site and corporate support; they are reduced commensurate with the staffing of the project.
The craft labor required to decontaminate and dismantle the nuclear unit is acquired through standard site contracting practices. The current cost of labor at the site is used as an estimating basis.
Security, while reduced from operating levels, is maintained throughout the decommissioning for access control, material control, and to safeguard the spent fuel.
A profile of the staffing levels for decommissioning, including contractors and craft, is provided in Figures 3.1 and 3.2 for the DECON and SAFSTOR scenarios, respectively. Utility staffing levels will gradually decrease after completing the removal of physical systems. Staffing levels and management support will vary based upon the amount and type of decommissioning work. Craft workforce levels decrease after systems removal and structures decontamination. Craft levels continue to decrease during the site restoration period as the work associated with structures demolition completes.
3.5.3 Design Conditions Any fuel cladding failure that occurred during the lifetime of the plant is assumed to have released fission products at sufficiently low levels that the buildup of quantities of long-lived isotopes (e.g., 137Cs, 90Sr, or transuranics) has been prevented from reaching levels exceeding those that permit the major NSSS components to be shipped under current transportation regulations and disposal requirements.
The curie contents of the vessel and internals at final shutdown are derived from those listed in NUREG/CR-3474.[31] Actual estimates are derived from the curie/gram values contained therein and adjusted for the different mass of the Callaway components, projected operating life, and different periods of decay. Additional short-lived isotopes are derived from CR-0130[32] and CR-0672,[33] and benchmarked to the long-lived values from CR-3474.
The control elements are disposed of along with the spent fuel, i.e., there is no additional cost provided for their disposal.
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 17 of 34 TLG Services, LLC Activation of the containment building structure is confined to the biological shield.
3.5.4 General Transition Activities Existing warehouses are cleared of non-essential material and remain for use by Ameren Services and its subcontractors. The plant 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 estimates do not address the disposition of any legacy wastes; the disposal of operating wastes during this initial period is not considered a decommissioning expense.
Scrap and Salvage The existing plant equipment is considered obsolete and suitable for scrap as deadweight quantities only. Ameren Services 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 requires expensive rework after the equipment had been removed from its installed location. Since placing a salvage value on this machinery and equipment would be speculative, and the value would be small in comparison to the overall decommissioning expenses, this analysis does not attempt to quantify the value that an owner may realize based upon those efforts.
It is assumed, for purposes of this analysis, that any value received from the sale of scrap generated in the dismantling process would be more than offset by the on-site processing costs. The dismantling techniques assumed in the decommissioning estimates do not include the additional cost for size reduction and preparation to meet furnace ready conditions.
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 18 of 34 TLG Services, LLC For example, the recovery of copper from electrical cabling may require the removal and disposition of any contaminated insulation, an added expense. With a volatile market, the potential profit margin in scrap recovery is highly speculative, regardless of the ability to free release this material. This assumption is an implicit recognition of scrap value in the disposal of clean metallic waste at no additional cost to the project.
Furniture, tools, mobile equipment such as forklifts, trucks, bulldozers, and other property is removed at no cost or credit to the decommissioning project. Disposition may include relocation to other facilities. Spare parts are also made available for alternative use.
Energy For estimating purposes, the plant is assumed to be de-energized, with the exception of those facilities associated with spent fuel storage.
Replacement power costs are used to calculate the cost of energy consumed during decommissioning for tooling, lighting, ventilation, and essential services.
Insurance Costs for continuing coverage (nuclear liability and property insurance) following cessation of plant operations and during decommissioning are included and based upon current operating premiums. Reductions in premiums, throughout the decommissioning process, are based upon the guidance provided in SECY-00-0145, Integrated Rulemaking Plan for Nuclear Power Plant Decommissioning[34] The NRCs financial protection requirements are based on various reactor (and spent fuel) configurations.
Taxes Property tax payments are included for the land only and will continue through the decommissioning project.
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.
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 19 of 34 TLG Services, LLC 3.6 COST ESTIMATE
SUMMARY
Schedules of expenditures for the base case are provided in Tables 3.1 and 3.2.
The tables delineate the cost contributors by year of expenditures as well as cost contributor (labor, equipment and materials, energy, radioactive waste disposal, and other costs).
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). The cost reported for this subcategory is generally sufficient to terminate the units operating license, recognizing that there may be some additional cost impact from spent fuel management. These costs are identified in Tables 3.1a and 3.2a.
The Spent Fuel Management subcategory contains costs associated with the five and one-half years of post-shutdown pool operations and the transfer of the fuel from the pool to the DOE. These costs are identified in Tables 3.1b and 3.2b.
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 below grade and backfilled to conform to local grade. These costs are identified in Tables 3.1c and 3.2c.
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 discussed in Section 3.4.1, while designated for disposal at the geologic repository along with the spent fuel, GTCC waste is still classified as low-level radioactive waste and, as such, included as a License Termination expense.
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 20 of 34 TLG Services, LLC The estimates were developed and costs are presented in 2023 dollars. As such, the estimates do not reflect the escalation of costs (due to inflationary and market forces) over the remaining operating life of the reactor or during the decommissioning period. The schedules are based upon the detailed activity costs reported in Appendices C and D, along with the timeline presented in Section 4.
For the purposes of this analysis, the costs presented in the following tables reflect plant decommissioning at the expiration of its current license (2044) and the use of off-site low-level radioactive waste processing to minimize the volume designated for controlled disposal. Costs for the direct disposal only scenarios are presented in the appendices (E and F).

- 4. SCHEDULE ESTIMATE The schedules for the decommissioning scenarios considered in this study follow the sequences presented in the AIF/NESP-036 study, with minor changes to reflect recent experience and site-specific constraints. In addition, the scheduling has been revised to reflect the spent fuel management plan described in Section 3.4.1.
A schedule or sequence of activities for the DECON alternative is presented in Figure 4.1. The scheduling sequence assumes that fuel is removed from the spent fuel pool within five and one-half years. The key activities listed in the schedule do not reflect a one-to-one correspondence with those activities in the cost tables, but reflect dividing some activities for clarity and combining others for convenience. The schedule was prepared using the "Microsoft Project Professional" computer software.[35]
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 fuel building is isolated until such time that all spent fuel has been transferred from the spent fuel pool to the DOE. Decontamination and dismantling of the storage pool is initiated once the transfer of spent fuel is complete (DECON option).
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.
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 4, Page 2 of 4 TLG Services, LLC 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. A second critical path is shown for the spent fuel storage period, which determines the release of the fuel building for final decontamination.
Project timelines are provided in Figures 4.2 and 4.3 with milestone dates based on a 2044 shutdown date. The fuel pool is emptied approximately five and one-half years after shutdown. Deferred decommissioning in the SAFSTOR scenarios is assumed to commence so that the operating license is terminated within a 60-year period from the cessation of plant operations.

- 5. RADIOACTIVE WASTES The objectives of the decommissioning process are the removal of all radioactive material from the site that would restrict its future use and the termination of the NRC license. This currently requires the remediation of all radioactive material at the site in excess of applicable legal limits. Under the Atomic Energy Act,[36] the NRC is responsible for protecting the public from sources of ionizing radiation. Title 10 of the Code of Federal Regulations delineates the production, utilization, and disposal of radioactive materials and processes. In particular, Part 71 defines radioactive material as it pertains to transportation and Part 61 specifies its disposition.
Most of the materials being transported for controlled burial are categorized as Low Specific Activity (LSA) or Surface Contaminated Object (SCO) materials containing Type A quantities, as defined in 49 CFR Parts 173-178. Shipping containers are required to be Industrial Packages (IP-1, IP-2 or IP-3, as defined in 10 CFR §173.411).
For this study, commercially available steel containers are presumed to be used for the disposal of piping, small components, and concrete. Larger components can serve as their own containers, with proper closure of all openings, access ways, and penetrations.
The destinations for the various waste streams from decommissioning are identified in Figures 5.1 and 5.2. The volumes of radioactive waste generated during the various decommissioning activities at the site are shown on a line-item basis in appendices, and summarized in Tables 5.1 and 5.2 (base case). 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 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 137Cs will still control the disposition requirements.
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 5, Page 2 of 6 The waste material produced in the decontamination and dismantling of the nuclear units is primarily generated during Period 2 of DECON and Period 4 of SAFSTOR.
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 processing and recycling.
For purposes of constructing the estimates, the cost for disposal at the EnergySolutions facility was used as a proxy for future disposal facilities. Separate rates were used for containerized waste and large components, including the steam generators and reactor coolant pump motors. Demolition debris including miscellaneous steel, scaffolding, and concrete was disposed of at a bulk rate. The decommissioning waste stream also included resins and dry active waste.
Since EnergySolutions is not currently able to receive the more highly radioactive components generated in the decontamination and dismantling of the reactor, disposal costs for the Class B and C material were based upon Ameren Services current agreement with WCS for the Andrews County disposal facility.
A small quantity of material generated during the decommissioning will not be considered suitable for near-surface disposal, and is assumed to be disposed of in a geologic repository, in a manner similar to that envisioned for spent fuel disposal.
This GTCC material, is estimated to require five spent fuel storage canisters (or the equivalent) to dispose of the most radioactive portions of the reactor vessel internals.
The volume and weight reported in Tables 5.1 and 5.2 represent the packaged weight and volume of the GTCC storage canisters.

- 6. RESULTS The analysis to estimate the costs to decommission Callaway relied upon the site-specific, technical information developed for a previous analysis prepared in 2020.
While not an engineering study, the estimates provide the plant owner with sufficient information to assess its financial obligations, as they pertain to the eventual decommissioning of the nuclear station.
The estimates described in this report are based on numerous fundamental assumptions, including 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 stations spent fuel pool for a minimum of five and one-half years following the cessation of operations for continued cooling of the assemblies. Once sufficiently cooled, the spent fuel will be packaged into canisters and transferred to the DOE. The spent fuel stored at the ISFSI will also be transferred to DOE during this period.
The cost projected to promptly decommission (DECON) Callaway, assuming the use of off-site low-level radioactive waste processing to reduce the volume requiring controlled disposal, is estimated to be $1,097.9 million. The majority of this cost (approximately 82.2%) is associated with the physical decontamination and dismantling of the nuclear unit so that the operating license can be terminated.
Another 7.2% is associated with the management, interim storage, and eventual transfer of the spent fuel. The remaining 10.6% is for the demolition of the designated structures and limited restoration of the site.
The cost projected for deferred decommissioning (SAFSTOR), assuming the use of off-site low-level radioactive waste processing to reduce the volume requiring controlled disposal, is estimated to be $1,435.4 million. The majority of this cost (approximately 85.2%) 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 6.7% is associated with the management, interim storage, and eventual transfer of the spent fuel. The remaining 8.1% is for the demolition of the designated structures and limited restoration of the site.
The primary cost contributors, identified in Tables 6.1 and 6.2, are either labor-related or associated with the management and disposition of the radioactive waste.
Program management is the largest single contributor to the overall cost. The magnitude of the expense is a function of both the size of the organization required to manage the decommissioning, as well as the duration of the program. It is
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 6, Page 2 of 5 TLG Services, LLC assumed, for purposes of this analysis, that Ameren Services 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 (for the DECON alternative).
As described in this report, the spent fuel pool will remain operational for a minimum of five and one-half years following the cessation of operations. The pool will be isolated and an independent spent fuel island created. This will allow decommissioning operations to proceed in and around the pool area. Over the five and one-half year period, the spent fuel will be packaged into canisters and transferred to the DOE. The spent fuel stored at the ISFSI will also be transferred to DOE during this period.
The cost for waste disposal includes those costs associated with the controlled disposition of the low-level radioactive waste generated from decontamination and dismantling activities, including plant equipment and components, structural material, filters, resins and dry-active waste. As described in Section 5, disposition of the low-level radioactive material required controlled disposal is at the EnergySolutions facility. Highly activated components, requiring additional isolation from the environment (GTCC), are packaged for geologic disposal. The cost of geologic disposal is based upon a cost equivalent for spent fuel.
A significant portion of the metallic waste is designated for additional processing and treatment at an off-site facility. Processing reduces the volume of material requiring controlled disposal through such techniques and processes as survey and sorting, decontamination, and volume reduction. The material that cannot be unconditionally released is packaged for controlled disposal at one of the currently operating facilities.
The cost identified in the summary tables for processing is all-inclusive, incorporating the ultimate disposition of the material.
Removal costs reflect the labor-intensive nature of the decommissioning process, as well as the management controls required to ensure a safe and successful program.
Decontamination and packaging costs also have a large labor component that is based upon prevailing 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
Callaway Energy Center Document A22-1819-001, Rev. 0 Decommissioning Cost Analysis Section 6, Page 3 of 5 TLG Services, LLC 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.
Decontamination is used to reduce the plant 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.
