Comanche Peak Nuclear Power Plant (CPNPP)
Docket Nos. 50-445 and 50-446 and 72-74 Decommissioning Report
Dear Sir or Madam:
Attached is the biennial decommissioning report for Comanche Peak Nuclear Power Plant (CPNPP) Units 1 and 2, prepared and submitted by Vistra Operations Company LLC (Vistra OpCo / operator) pursuant to 10CFR50.75(f) and 10CFR72.30(c). Comanche Peak Power Company LLC (CP PowerCo / owner) is an unregulated utility and therefore does not meet the definition of an electric utility as defined by 10CFR50.2.
The recovery of decommissioning funds for the eventual decommissioning of CPNPP Units 1 and 2 is assured through the collection of a non-bypassable charge which is subsequently contributed to an external trust.
The applicable sections of the citation (e.g., an Order by the rate-regulatory authority) by the regulatory authority that allows for the collection of non-bypassable charges established for the collection of decommissioning funds estimated to be required under 10 CFR 50.75(b) and (c) is provided below.
The distribution utility will collect from customers and the generation company will contribute all funds collected to the decommissioning trust fund:
- Enclosure to TXX-21066, Public Utility Commission of Texas (PUCT) Docket No. 50945, Item No. 23, Order dated January 29, 2021, page 2 of 7, paragraph #11.
The annual collection rate for each unit:

- Enclosure to TXX-21066, PUCT Docket No. 50945, Item No. 23, Order dated January 29, 2021, Page 7 of 7, paragraph #1 and 2 of Section III.
Also, pursuant to the requirements of 10 CFR 72.30(c), Vistra OpCo is submitting the 2021 Decommissioning Funding Status Report for Comanche Peak Nuclear Power Plant (CPNPP) Independent Spent Fuel Storage Installation, Docket No. 72-74 (CPNPP ISFSI). Attachment 2 to this letter contains the information required by 10 CFR 72.30(b).
The amounts to be collected for CPNPP decommissioning are based on a site specific decommissioning study that includes direct waste disposal. In addition, the radiological cost component breakdown of the 2019 Site Specific cost is included in the 2020 Financial Assurance filing (Enclosure to TXX-21066, PUCT Docket No.
50945, Item No. 1, Comanche Peak Power Company LLC Filing dated June 16, 2020, document Lll-1774-001, Rev. 0, Page xx of xxi).
TXX-21066 Page2 of2 When projected to the license expiration date for each unit using the 2 percent annual real rate of return as allowed per 10CFR50.75(e)(ii), the projected Nuclear Decommissioning Trust balance is greater than the escalated NRC minimum cost of decommissioning for Units 1 and 2.

to TXX-21066 Page I of3 2021 Decommissioning Funding Status Report for Comanche Peak Nuclear Power Plant Units 1 and 2 Independent Spent Fuel Storage Installation Pursuant to 10 CFR 72.30(c), each licensee for an Independent Spent Fuel Storage Installation (ISFSI), including an ISFSI licensed under the General License provided for in 10 CFR Part 72, Subpart K, is required, at intervals not to exceed 3 years, to resubmit a decommissioning funding plan with adjustments as necessary to account for changes in costs and the extent of contamination, as well as information regarding the financial assurance provided for funding such costs. Vistra Operations Company LLC (Vistra OpCo) provides the following information regarding the Comanche Peak Nuclear Power Plant (CPNPP) Units 1 and 2 Independent Spent Fuel Storage Installation, Docket No. 72-74 (CPNPP ISFSI):
- 1. Information on how reasonable assurance will be provided that funds will be available to decommission the ISFSI:
See response to number 4 below, which discusses the appropriate method of financial assurance contemplated under 10 CFR 72.30(e).
- 2. A detailed cost estimate (DCE) for decommissioning:
In a report dated May 2020, TLG Services, Inc. (TLG) (Enclosure to TXX-21066) prepared a site specific Decommissioning Cost Study (with an adequate contingency factor) for the Comanche Peak Nuclear Power Plant (CPNPP) that included the costs of decommissioning the ISFSI. The TLG Report determined the total cost of decommissioning the CPNPP ISFSI to be:
2019 Dollars Escalation Factor (%) 2020 Dollars (million) (from TLG Report) (million)
(Notel) (Note2)
Unitl 5.2 2.668 5.35 Unit2 5.2 2.640 5.34 Total 10.69 This cost estimate includes the cost of an independent contractor to perform all decommissioning activities and the cost of meeting the 10 CFR 20.1402 criteria for unrestricted release.
Below is the effect of the following on the detailed cost estimate since the previous report.
Spills of radioactive material producing additional None residual radioactivity in onsite subsurface material Facility modifications None (Note3)
Changes in authorized possession limits None to TXX-21066 Page 2 of3 2021 Decommissioning Funding Status Report for Comanche Peak Nuclear Power Plant Units 1 and 2 Independent Spent Fuel Storage Installation Actual remediation costs that exceed the previous None cost estimate
- 3. Identification of and justification for using the key assumptions contained in the decommissioning cost estimate:
The assumptions used in the development of the decommissioning cost estimate and their justification can be found in the TLG Report.
- 4. A description of the method of assuring funds for decommissioning from 10 CFR 72.30(e), including means of adjusting cost estimates and associated funding levels periodically over the life of the facility:
Vistra OpCo is using the external sinking fund method as authorized in 10 CFR 72.30(e)(5) and 50.75(e)(l)(ii). Vistra OpCo recovers its costs for decommissioning through cost of service ratemaking, including the estimated costs to decommission the CPNPP ISFSI, which are included in the TLG Report. Pursuant to Substantive Rule 25.303(£)(2) of the Public Utility Commission of Texas (PUCT), the TLG Report is updated, and the required annual funding amount necessary to decommission CPNPP is adjusted under the jurisdiction of the PUCT.
In the event that funds remaining to be placed into the Vistra OpCo' s external sinking funds are no longer approved for recovery in rates by competent rate making authorities, Vistra OpCo will make changes to provide financial assurance using one or more of the methods stated in 10 CFR 72.30(e)(l)-(4).
- 5. The volume of onsite subsurface material containing residual radioactivity that will require remediation to meet the criteria for license termination:
There has been no event at the ISFSI facility to lead us to believe there is subsurface contamination. Therefore, Vistra OpCo assumes that there is no volume of onsite subsurface material containing residual radioactivity that will require remediation to meet the criteria for license termination.
- 6. A certification that financial assurance for decommission has been provided in the amount of the cost estimate for decommissioning:
The submission of this report serves as certification that financial assurance has been provided in the amount of the cost estimate for decommissioning.

§ 25.303(f)(2)
In compliance with 16 Tex. Admin. Code (TAC) § 25.303(0(2), Comanche Peak Power Company LLC ("Comanche Peak"), as Transferee Company, hereby files:
(1) A study of the decommissioning costs of Comanche Peak Nuclear Power Plant ("CPNPP"),
the Decommissioning Cost Analysis for the Comanche Peak Nuclear Power Plant, prepared by TLG Services, Inc. dated May 2020 ("Decommissioning Study") (Attachment A);
(2) A financial escalation analysis of the decommissioning costs of CPNPP, the Financial Escalation Analysis for the Comanche Peak Nuclear Power Plant, prepared by TLG Services, Inc. dated May 2020 ("Financial Escalation Analysis") (Attachment B); and (3) An updated funding analysis, the Funding Analysis for Comanche Peak Nuclear Power Plant, prepared by Comanche Peak dated June 2020 ("Funding Analysis") (Attachment C).
The Funding Analysis calculates the required annual funding amount necessary to ensure sufficient funds to decommission both units of CPNPP, which, according to the Financial Escalation Analysis, is
$1,729 million in 2019 dollars for the prompt decommissioning alternative ("DECON") with a 10 percent contingency (see Tables 4 and 5). As shown on page 24 of Exhibit 4 of the Funding Analysis, an annual amount of $19.4 million throughout the remaining operating life of CPNPP is necessary to fully fund the anticipated decommissioning costs for CPNPP Units 1 and 2.
6555 SIERRA DRIVE IRVING, IEXAS 75034 o 213-875-8004 VIS1RAENERGI COM Lumlnant
June 16, 2020, Page 2 The Funding Analysis additionally contains within the study a description of the assumptions used in the analysis. Although the Decommissioning Study recommended an appropriate contingency of approximately 17.29 percent for Unit 1 and 17.55 percent for Unit 2 for the DECON alternative (see Appendix C), in compliance with 16 TAC § 25.303(0(2), an allowance for contingency of 10 percent was used in the Financial Escalation Analysis and Funding Analysis. In addition, because there is only a -2.7 percent difference between the required funding levels resulting from the Funding Analysis ($19.4 million) and the five year average CPNPP decommissioning fund collections from 2015-2019 ($19.9 million annually) and because of the assumptions in the Decommissioning Study, Financial Escalation Analysis, and Funding Analysis likely have inherent and considerable uncertainty based on the predictability of long-term costs and market conditions, Comanche Peak proposes no change in the current collection rate. Comanche Peak does propose an adjustment in the allocation between the Unit 1 and Unit 2 decommissioning funds from 57.1 percent for Unit 1 and 42.9 percent for Unit 2 to 72.3 percent for Unit 1 and 27.7 percent for Unit 2 (see page 24 of Exhibit 4 of the Funding Analysis).

SUMMARY
This report presents estimates of the cost to decommission the Comanche Peak Nuclear Power Plant (Comanche Peak) for the selected decommissioning alternatives following the scheduled and permanent cessation of plant operations. The estimates are designed to provide Comanche Peak Power Company LLC (CPPC) with sufficient information to assess its financial obligations, as they pertain to the decommissioning of Comanche Peak.
The analysis relies upon site-specific, technical information from an evaluation prepared in 2014,[1] updated to reflect current plant inventory, current assumptions pertaining to the operating life of the reactor, disposition of the two nuclear units 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 estimates prepared in advance of the detailed engineering required to carry out the decommissioning of Comanche Peak. It may also not reflect the actual plan to decommission Comanche Peak; the plan may differ from the assumptions made in this analysis based on facts that exist at the time of decommissioning.
The 2014 plant inventory, the basis for the decontamination and dismantling requirements and cost, and the decommissioning waste streams, were reviewed for this analysis. The only substantive changes made to the plant inventory from the 2014 analysis (that would impact decommissioning) is the addition of the Stator Rewind building.
The costs to decommission Comanche Peak for the alternatives evaluated are tabulated at the end of this section. Costs are reported in 2019 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 each scenario. A sequence of significant project activities is provided in Section 4 with timelines for each scenario. Detailed cost reports used to generate the summary tables contained within this document are provided in Appendices C and D.
1 "Decommissioning Cost Study for the Comanche Peak Nuclear Power Plant," Document L11-1703-001, Rev. 0, TLG Services, Inc., May 2015 TLG Services, Inc. 000011
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Page ix of xxi Consistent with the 2014 analysis, the current cost estimates assume that the shutdown of the nuclear units 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). 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 Unit 2 operations cease. During this time period, it is assumed that the spent fuel residing in the pools will be transferred to an independent spent fuel storage installation (ISFSI) located on the site. The ISFSI will remain operational until the Department of Energy (DOE) is able to complete the transfer of the fuel to a federal facility (e.g., a monitored retrievable storage facility).[21 Alternatives and Regulations The Nuclear Regulatory Commission (NRC) provided initial decommissioning requirements in its rule adopted on June 27, 1988.131 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."[41 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."[51 Decommissioning is to be completed within 60 years, although longer time periods will be considered when necessary to protect public health and safety.
Projected expenditures for spent fuel management identified in the cost analyses do not consider any compensation from the DOE with regard to the delays incurred by CPPC in the timely removal of spent fuel from the site.

Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Page x of xxi 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."[6] 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 2017, the NRC's staff issued the regulatory basis for proposed new regulations on the decommissioning of commercial nuclear power reactors. In the regulatory basis, the NRC staff proposed removing any discussion of the ENTOMB option from existing guidance documents "since the method is not deemed practically feasible for current U.S. power reactors, and the timeframe for decommissioning completion using the ENTOMB method is generally inconsistent with current regulations."[71 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.E8] 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 acceptable to the NRC staff for implementing the requirements of the 1996 revised rule relating to the initial activities and major phases of the decommissioning process.
The costs and schedules presented in this analysis follow the general guidance and processes described in the amended regulations. The format and content of the estimates is also consistent with the recommendations of Regulatory Guide 1.202, issued in February 2005.[9]

Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Page xi of xxi 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.R0I The regulations require licensees to report additional details in their decommissioning cost estimate, including a decommissioning estimate for the ISFSI. This estimate is provided in Appendix E.
Comanche Peak Decommissioning Scenarios Two decommissioning scenarios were evaluated for Comanche Peak. The scenarios selected are representative of alternatives currently available to CPPC and are defined as follows:
- 1. The first scenario assumes that the units would be promptly decommissioned (DECON alternative) upon the expiration of the current operating licenses, i.e.,
2030 and 2033 for Units 1 and 2, respectively. Spent fuel in the wet storage pools would be relocated to the ISFSI for interim storage until such time that the DOE can complete the transfer, presumed to be in the year 2095.
- 2. In the second scenario, the nuclear units are placed into safe-storage (SAFSTOR alternative) at the end of their current operating licenses. Spent fuel in wet storage pools at that time would be relocated to the ISFSI for interim storage so as to minimize caretaking costs. The fuel would be transferred to the DOE (consistent with the assumptions in the DECON scenario) until the process is presumed to be complete in the year 2095. Decommissioning is deferred to the maximum extent (approximately 50 years) such that the property is released for unrestricted use within the generally required 60-year period (i.e., 2090, based upon the current Unit 1 shutdown date).
Methodology The methodology used to develop the estimates described within this document follows the basic approach originally presented in the cost estimating guidelines[111 developed by the Atomic Industrial Forum (now Nuclear Energy Institute). This reference describes a unit factor method for determining decommissioning activity costs. The unit factors used in this analysis incorporate site-specific costs and the latest available information on worker productivity in decommissioning.

Comanche Peak Nuclear Pozver Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Page xii of xxi An activity duration critical path is used to determine the total decommissioning program schedule. This is required for calculating the carrying costs, which include program management, administration, field engineering, equipment rental, quality assurance, and security. This systematic approach for assembling decommissioning estimates ensures a high degree of confidence in the reliability of the resulting costs.
The estimates also reflect lessons learned from TLG's involvement in the Shippingport Station Decommissioning Project, completed in 1989, as well as the decommissioning of the Cintichem reactor, hot cells and associated facilities, completed in 1997. In addition, the planning and engineering for the 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 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."[1-2] The cost elements in the estimates are based on ideal conditions; therefore, the types of unforeseeable events that are almost certain to occur in decommissioning, based on industry experience, are addressed through a percentage contingency applied on a line-item basis. This contingency factor is a nearly universal element in all large-scale construction and demolition projects. It should be noted that contingency, as used in this analysis, does not account for price escalation and inflation in the cost of decommissioning over the remaining operating life of the nuclear units.
Contingency funds are expected to be fully expended throughout the program. As such, inclusion of contingency is necessary to provide assurance that sufficient funding will be available to accomplish the intended tasks.
Low-Level Radioactive Waste Management 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,[131 and its 12 Project and Cost Engineers' Handbook, Second Edition, American Association of Cost Engineers, Marcel Dekker, Inc., New York, New York, p. 239 13 "Low-Level Radioactive Waste Policy Act of 1980," Public Law 96-573, 1980 TLG Services, Inc. 000015
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Page xiii of xxi Amendments of 1985,[141 the States became ultimately responsible for the disposition of low-level radioactive waste generated within their own borders.
The Texas Compact disposal facility is now operational and waste is being accepted from generators including CPPC by the operator, Waste Control Specialists (WCS).
For the purposes of this analysis, low-level radioactive waste generated in the decontamination and dismantling of the plant and remediation of the Comanche Peak site, and designated for direct disposal, is assumed to be shipped to the Texas Compact site. Waste disposal costs are based upon the Environmental Service Agreement for the disposal of low-level radioactive waste at the Texas Compact waste disposal facility between CPPC and 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 or GTCC.
The Low-Level Radioactive Waste Policy Amendments Act of 1985 assigns the federal government the responsibility for the disposal of this material. The Act also states that the beneficiaries of the activities resulting in the generation of such radioactive waste bear all reasonable costs of disposing of such waste. However, to date, the federal government has not identified a cost, if any, for GTCC disposal 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 manner similar to 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 stored on site (at the ISFSI). The GTCC is assumed to be transferred to a designated Federal disposal facility once the spent fuel has been removed from the site.
High-Level Radioactive Waste Management Congress passed the "Nuclear Waste Policy Act"[1-51 (NWPA) in 1982, assigning the federal government's long-standing responsibility for disposal of the spent nuclear fuel and high level radioactive waste created by the commercial nuclear generating plants to the DOE. The NWPA provides that DOE will enter into contracts with utilities in which DOE promises to take the utilities' spent fuel and high-level radioactive waste and utilities will pay the cost of the disposition services for that material. The NWPA, 14 "Low-Level Radioactive Waste Policy Amendments Act of 1985," Public Law 99-240, 1986 15 "Nuclear Waste Policy Act of 1982 and Amendments," DOE's Office of Civilian Radioactive Management, 1982 TLG Services, Inc. 000016
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Page xiv of xxi along with the individual contracts with the utilities, specifies that the DOE was to begin accepting spent fuel by January 31, 1998.
Today, the country is at an impasse on high-level waste disposal, despite DOE's 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."[161 Towards this goal, the Obama administration appointed a Blue Ribbon Commission on America's Nuclear Future (Blue Ribbon Commission) to make recommendations for a new plan for nuclear waste disposal. The Blue Ribbon Commission's charter included a requirement that it consider "[o]ptions for safe storage of used nuclear fuel while final disposition pathways are selected and deployed."[171 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:
o "[T]he United States [should] establish a program that leads to the timely development of one or more consolidated storage facilities."0-81 o "[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."[191 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..."[201 16 "Advisory Committee Charter, Blue Ribbon Commission on America's Nuclear Future," Appendix A, January 2012 17 Ibid.

Comanche Peah Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Page xv of xxi "With the appropriate authorizations from Congress, the Administration currently plans to implement a program over the next 10 years that:
o 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; O 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."[211 The NRC's review of DOE's 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 appropriated funding for the review. That review is now complete with the publication of the five-volume safety evaluation report. A supplement to DOE's environmental impact statement and an 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 DOE's 2013 strategy was issued except for the completion of the Yucca Mountain safety evaluation report.
Completion of the decommissioning process is dependent upon the DOE's ability to remove spent fuel from the site in a timely manner. DOE's repository program assumes that spent fuel allocations will be accepted for disposal from the nation's commercial nuclear plants, with certain exceptions defined in the DOE Contract, in the order (the "queue") in which it was discharged from the reactor.[231 CPPC's current spent fuel 21 Ibid., p.2 22 U.S. Court of Appeals for the District Of Columbia Circuit, In Re: Aiken County, et al, Aug.
2013,http://www.cadc.uscourts.gov/internet/opinions.nsf/BAEOCF3z1F762EBD985257BCGOO4DE B18/$file/11-1271-1451347.pdf 23 In 2008, the DOE issued a report to Congress in which it concluded that it did not have authority, under present law, to accept spent nuclear fuel for interim storage from decommissioned commercial nuclear power reactor sites. However, the Blue Ribbon Commission, in its final report, noted that:
"[A]ccepting spent fuel according to the OFF [Oldest Fuel First] priority ranking instead of giving priority to shutdown reactor sites could greatly reduce the cost savings that could be TLG Services, Inc. 000018
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Page xvi of xxi management plan for the Comanche Peak spent fuel is based in general upon: 1) a 2056 start date for DOE initiating transfer of Comanche Peak spent fuel to a federal facility (not necessarily a final repository), and 2) a spent fuel transfer 2095 completion date.
Different DOE acceptance assumptions would result in different completion dates.
The 2056 start date for DOE acceptance of Comanche Peak spent fuel is based on assumed initial operation of the nation's first federal facility (not necessarily a final repository) in 25 years (2045) and Comanche Peak's place in the Oldest Fuel First (OFF) spent fuel queue per the schedule provided in DOE/RW-0567, Acceptance Priority Ranking & Annual Capacity Report.[241 DOE/RW-0567 also assumes an annual cap of 3000 metric tons of uranium (MTU) on its ability to accept spent nuclear fuel. Pursuant to that assumption, it is estimated that CPPC will be able to ship between 50 and 60 MTU per year from Comanche Peak to a federal interim storage facility or a geologic repository. This is an equivalent of 118 to 142 fuel assemblies per year, or approximately 4 dry cask containers (128 spent fuel assemblies) per year. At this rate, all spent fuel is estimated to be removed from the Comanche Peak site by 2095.
The NRC requires that licensees establish a program to manage and provide funding for the caretaking of all irradiated fuel at the reactor site until title of the fuel is transferred to the DOE.[251Interim storage of the fuel, until the DOE has completed the transfer, will be in the fuel building's spent fuel storage pools, as well as at an on-site ISFSI.
achieved through consolidated storage if priority could be given to accepting spent fuel from shutdown reactor sites before accepting fuel from still-operating plants. .... The magnitude of the cost savings that could be achieved by giving priority to shutdown sites appears to be large enough (i.e., in the billions of dollars) to warrant DOE exercising its right under the Standard Contract to move this fuel first." For planning purposes only, this estimate does not assume that Comanche Peak, as a permanently shutdown station, will receive priority; the fuel removal schedule assumed in this estimate is based upon DOE acceptance of fuel according to the "Oldest Fuel First" priority ranking. The plant owner will seek the most expeditious means of removing fuel from the site when DOE commences performance.
24 DOE/RW-0567 was published in July 2004 by the Department of Energy Office of Civilian Radioactive Waste Management. Although an alternate location may be sited in the future, the referenced study based on Yucca Mountain is the most recent report issued by DOE.
25 U.S. Code of Federal Regulations, Title 10, Part 50, "Domestic Licensing of Production and Utilization Facilities," Subpart 54 (bb), "Conditions of Licenses" TLG Services, Inc. 000019
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Page xvii of xxi An ISFSI, operated under a Part 50 General License (in accordance with 10 CFR 72, Subpart K1261), has been constructed to support continued plant operations. The facility will be expanded at Comanche Peak to support future decommissioning operations.
Once the spent fuel storage pools are emptied, the fuel building can be either decontaminated and dismantled or prepared for long term storage.
DOE has breached its obligations to remove fuel from reactor sites, and has also failed to provide CPPC with information about how it will ultimately perform. DOE officials have stated that DOE does not have an obligation to accept already-canistered fuel without an amendment to DOE's contracts with plant licensees to remove the fuel (the "Standard Contract"), but DOE has not explained what any such amendment would involve. Consequently, CPPC has no information or expectations on how DOE will remove fuel from the site in the future. In the absence of information about how DOE will perform, and for purposes of this analysis only, it is assumed that DOE will accept already-canistered fuel. If this assumption is incorrect, it is assumed that DOE will have liability for costs incurred to transfer the fuel to DOE-supplied containers.
CPPC's position is that the DOE has a contractual obligation to accept the spent fuel earlier than the projections set out above consistent with its contract commitments. No assumption made in this study should be interpreted to be inconsistent with this claim.
However, at this time, including the cost of storing spent fuel in this study is the most reasonable approach because it insures the availability of sufficient decommissioning funds at the end of the station's life if, contrary to its contractual obligation, the DOE has not performed earlier.
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 deferre d.
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.
26 U.S. Code of Federal Regulations, Title 10, Part 72, Subpart K, "General License for Storage of Spent Fuel at Power Reactor Sites" TLG Services, Inc. 000020
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Page xviii of xxi Summary The cost to decommission Comanche Peak assumes the removal of all contaminated and activated plant components and structural materials such that CPPC may then have unrestricted use of the site with no further requirements for an operating license. Low-level radioactive waste, other than GTCC waste, is sent to a controlled disposal facility.
Decommissioning and subsequent License Termination, exclusive of the ISFSI, is accomplished within the 60-year period required by current NRC regulations. Spent fuel remains in storage at the site until such time that the transfer to a DOE facility is complete (assumed to be 2095 for purposes of this analysis). Once the transfer is complete, the ISFSI is decommissioned and the site released for unrestricted use.
The decommissioning scenarios are described in Section 2. The assumptions are presented in Section 3, along with schedules of annual expenditures. The major cost contributors are identified in Section 6, with detailed activity costs, waste volumes, and associated manpower requirements delineated in Appendices C and D for the DECON and SAFSTOR alternatives. The major cost components are also identified in the cost summary provided at the end of this section.
The cost elements in the estimates are assigned to one of three subcategories: NRC License Termination, Spent Fuel Management, and Site Restoration. The subcategory "NRC License Termination" is used to accumulate costs that are consistent with "decommissioning" as defined by the NRC in its financial assurance regulations (i.e., 10 CFR Part 50.75). The cost reported for this subcategory is generally sufficient to terminate the operating licenses for the two reactors, recognizing that there may be some additional cost impact from spent fuel management. This subcategory also includes the costs of disposing of the retired steam generators and the reactor vessel closure head from Unit 1. The study assumes that the disposal of the components would occur after shutdown; however, the costs are identified separately because the disposal activities could be conducted at any time. The License Termination cost subcategory also includes costs to decommission the ISFSI (as required by 10 CFR §72.30). Section 3.5.1 provides the basis for the ISFSI decommissioning cost.
The "Spent Fuel Management" subcategory contains costs associated with the containerization and transfer of spent fuel from the wet storage pools to the ISFSI for interim storage, as well as the transfer of the spent fuel in storage at the ISFSI to the DOE. Costs are included for the expansion of the existing ISFSI to accommodate all of the spent fuel generated during plant operations, operation of the fuel building's storage pools until the spent fuel is transferred to the ISFSI, and the management of the ISFSI until such time that the transfer to DOE 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.
TLG Services, Inc. 000021
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Page xix of xxi "Site Restoration" is used to capture costs associated with the dismantling and demolition of buildings and facilities demonstrated to be free from contamination. This includes structures never exposed to radioactive materials, as well as those facilities that have been decontaminated to appropriate levels. Structures are removed to a depth of three feet and backfilled to conform to local grade.
It should be noted that the costs assigned to these subcategories are allocations.
Delegation of cost elements is for the purposes of comparison (e.g., with NRC financial guidelines) or to permit specific financial treatment (e.g., Asset Retirement Obligation determinations). In reality, there can be considerable interaction between the activities in the three subcategories. For example, an owner may decide to remove non-contaminated structures early in the project to improve access to highly contaminated facilities or plant components. In these instances, the non-contaminated removal costs could be reassigned from Site Restoration to an NRC License Termination support activity. However, in general, the allocations represent a reasonable accounting of those costs that can be expected to be incurred for the specific subcomponents of the total estimated program cost, if executed as described.
As noted within this document, the estimates were developed and costs are presented in 2019 dollars. As such, the estimates do not reflect the escalation of costs (due to inflationary and market forces) over the remaining operating life of the station or during the decommissioning period.

- 1. INTRODUCTION This report presents estimates of the costs to decommission the Comanche Peak Nuclear Power Plant (Comanche Peak) for the selected decommissioning alternatives following the scheduled and permanent cessation of plant operations. The current estimates are designed to provide Comanche Peak Power Company LLC (CPPC) with sufficient information to assess their financial obligations, as they pertain to the decommissioning of Comanche Peak.
The analysis relies upon site-specific, technical information from an earlier evaluation prepared in 2014,[1]* updated to reflect current plant inventory, current assumptions pertaining to the operating life of the reactor, 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 station. It may also not reflect the actual plan to decommission Comanche Peak; the plan may differ from the assumptions made in this analysis based on facts that exist at the time of decommissioning.
The 2014 plant inventory, the basis for the decontamination and dismantling requirements and cost, and the decommissioning waste streams, were reviewed for this analysis. The only substantive changes made to the plant inventory from the 2014 analysis (that would impact decommissioning) is the addition of the Stator Rewind building.
1.1 OBJECTIVES OF STUDY The objectives of this analysis are to present comprehensive estimates of the costs to decommission Comanche Peak, to provide a sequence or schedule for the associated activities, and to identify the waste streams expected from the decontamination and dismantling activities.
For the purposes of this study, the shutdown dates for the two units are assumed to be on February 8, 2030, for Unit 1 and on February 2, 2033, for Unit 2, based upon the expiration of the current operating licenses.

The nearest communities are Glen Rose and Granbury, about 4 and 10 miles, respectively, from the site. The station is comprised of two nuclear units that are essentially identical except for certain auxiliary systems.
The two nuclear steam supply systems (NSSS) each consist of a pressurized water reactor and a four-loop reactor coolant system. They are authorized to operate at 3,612 megawatts (thermal), following approval of a stretch power uprate application in 2008.
Each of the four loops of the reactor coolant system contains a vertical U-tube type steam generator and a single speed centrifugal reactor coolant pump. In addition, the system includes an electrically heated pressurizer, a pressurizer relief tank, and interconnected piping. The reactor coolant system is housed within a containment vessel, a free-standing cylindrical steel structure enclosed by a separate reinforced concrete reactor building. The Containment Building is designed to provide biological shielding as well as missile protection for the steel containment vessel. '[LG1] The containment shell is anchored to the Containment Building foundation with a steel liner plate encased in concrete forming the base of the containment.
Heat produced in the reactor is converted to electrical energy by the steam and power conversion system. A turbine-generator system converts the thermal energy of steam produced in the steam generators into mechanical shaft power and then into electrical energy. The turbine generators consist of a tandem (single shaft) arrangement of a double-flow high-pressure turbine and two identical double-flow, low-pressure turbines driving a direct-coupled generator at 1800 rpm. The turbines are operated in a closed feedwater cycle, which condenses the steam. The heated feedwater is then returned to the steam generators. The condenser circulating water system removes heat rejected in the main condensers. The heat is dissipated to Squaw Creek Reservoir.

Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 1, Page 3 of 9 1.3 REGULATORY GUIDANCE The Nuclear Regulatory Commission (NRC) provided initial decommissioning requirements in its rule "General Requirements for Decommissioning Nuclear Facilities," issued in June 1988.121 This rule set forth financial criteria for decommissioning licensed nuclear power facilities. The regulation addressed decommissioning planning needs, timing, funding methods, and environmental review requirements. The intent of the rule was to ensure that decommissioning would be accomplished in a safe and timely manner and that adequate funds would be available for this purpose. Subsequent to the rule, the NRC issued Regulatory Guide 1.159, "Assuring the Availability of Funds for Decommissioning Nuclear Reactors,"[31 which provided additional guidance to the licensees of nuclear facilities on the financial methods acceptable to the NRC staff for complying with the requirements of the rule. The regulatory guide addressed the funding requirements and provided guidance on the content and form of the financial assurance mechanisms indicated in the rule.
The rule defined three decommissioning alternatives as being acceptable to the NRC: DECON, SAFSTOR, and ENTOMB. The DECON alternative assumes that any contaminated or activated portion of the plant's systems, structures and facilities are removed or decontaminated to levels that permit the site to be released for unrestricted use shortly after the cessation of plant operations.
The rule also placed limits on the time allowed to complete the decommissioning process. For all alternatives, 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. At the conclusion of a 60-year dormancy period (or longer if the NRC approves such a case), the site would still require significant remediation to meet the unrestricted release limits for license termination.
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 2017, the NRC's staff issued the regulatory basis for proposed new regulations on the decommissioning of commercial nuclear power reactors. In the regulatory basis, the NRC staff proposed removing any discussion of the ENTOMB option from existing guidance documents "since the method is not deemed practically feasible for current U.S. power reactors, and the timeframe for decommissioning completion using the ENTOMB method is generally inconsistent with current regulations."[4].
In 1996, the NRC published revisions to the general requirements for decommissioning nuclear power plants[51 When the decommissioning regulations were adopted in 1988, it was assumed that the majority of licensees TLG Services, Inc. 000027
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 1, Page 4 of 9 would decommission at the end of the facility's operating licensed life. Since that time, several licensees permanently and prematurely ceased operations.
Exemptions from certain operating requirements were required once the reactor was defueled to facilitate the decommissioning. Each case was handled individually, without clearly defined generic requirements. The NRC amended the decommissioning regulations in 1996 to clarify ambiguities and codify procedures and terminology as a means of enhancing efficiency and uniformity in the decommissioning process. The amendments allow for greater public participation and better define the transition process from operations to decommissioning.
Under the revised regulations, licensees will submit written certification to the NRC within 30 days after the decision to cease operations. Certification will also be required once the fuel is permanently removed from the reactor vessel.
Submittal of these notices, along with related changes to Technical Specifications, entitle the licensee to a fee reduction and eliminate the obligation to follow certain requirements needed only during operation of the reactor.
Before or within two years following cessation of operations, the licensee must 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 includes 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.[6] The regulations require licensees to report additional details in their decommissioning cost estimate including a decommissioning estimate for the ISFSI. This estimate is provided in Appendix E.
1.3.1 Low-Level Radioactive Waste Management 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, [71 and its Amendments of 1985,[81 the States became ultimately responsible for the disposition of low-level radioactive waste generated within their own borders.
TLG Services, Inc. 000028
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 1, Page 5 of 9 The Texas Compact disposal facility is now operational and waste is being accepted from generators including CPPC by the operator, Waste Control Specialists (WCS).
For the purposes of this analysis, low-level radioactive waste generated in the decontamination and dismantling of the plant and remediation of the Comanche Peak site, and designated for direct disposal, is assumed to be shipped to the Texas Compact site. Waste disposal costs are based upon the Environmental Service Agreement for the disposal of low-level radioactive waste at the Texas compact waste disposal facility between CPPC and 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 or GTCC). The Low-Level Radioactive Waste Policy Amendments Act of 1985 assigns the federal government the responsibility for the disposal of this material. The Act also states that the beneficiaries of the activities resulting in the generation of such radioactive waste bear all reasonable costs of disposing of such waste. However, to date, the federal government has not identified a cost, if any, for GTCC disposal 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 manner similar to 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 stored on site ( at the ISFSI). The GTCC is assumed to be transferred to a designated federal disposal facility once the spent fuel has been removed from the site.
1.3.2 High-Level Radioa'ctive Waste Management Congress passed the "Nuclear Waste Policy Act"[9] (NWPA) in 1982, assigning the federal government's long-standing responsibility for disposal of the spent nuclear fuel and high level radioactive waste created by the commercial nuclear generating plants to the DOE. The NWPA provides that DOE will enter into contracts with utilities in which DOE promises to take the utilities' spent fuel and high-level radioactive waste and utilities will pay the cost of the disposition services for that material. The NWPA, along with the individual contracts with the utilities, specifies that the DOE was to begin accepting spent fuel by January 31, 1998.
TLG Services, Inc. 000029
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 1, Page 6 of 9 Today, the country is at an impasse on high-level waste disposal, despite DOE's submittal of its License Application for a geologic repository to the NRC in 2008. The Obama administration eliminated the budget for the repository program and 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 America's Nuclear Future (Blue Ribbon Commission) to make recommendations for a new plan for nuclear waste disposal. The Blue Ribbon Commission's charter includes a requirement that it consider
"[o]ptions for safe storage of used nuclear fuel while final disposition pathways are selected and deployed."[N]
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."[111 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..."[12]
"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 TLG Services, Inc. 000030
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 1, Page 7 of 9 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 NRC's review of DOE's 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) 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 DOE's environmental impact statement and an 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 DOE's 2013 strategy was issued except for the completion of the Yucca Mountain safety evaluation report.
Completion of the decommissioning process is dependent upon the DOE's ability to remove spent fuel from the site in a timely manner. DOE's repository program assumes that spent fuel allocations will be accepted for disposal from the nation's commercial nuclear plants, with certain exceptions defined in the DOE Contract, in the order (the "queue") in which it was discharged from the reactor. CPPC's current spent fuel management plan for the Comanche Peak spent fuel is based in general upon: 1) a 2056 start date for DOE initiating transfer of Comanche Peak spent fuel to a federal facility (not necessarily a final repository), and 2) a spent fuel transfer 2095 completion date. Different DOE acceptance assumptions would result in different completion dates.
The 2056 start date for DOE acceptance of Comanche Peak spent fuel is based on assumed initial operation of the nation's first federal facility (not necessarily a final repository) in 25 years (2045) and Comanche Peak's place in the Oldest Fuel First (OFF) spent fuel queue per the schedule provided in DOE/RW-0567, Acceptance Priority Ranking & Annual Capacity Report.[131 DOE/RW-0567 also assumes an annual cap of 3000 metric tons of uranium (MTU) on its ability to accept spent nuclear fuel. Pursuant to that assumption, it is estimated that CPPC will be able to ship between 50 TLG Services, Inc. 000031
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 1, Page 8 of 9 and 60 MTU per year from Comanche Peak to a federal interim storage facility or a geologic repository. This is an equivalent of 118 to 142 fuel assemblies per year, or approximately 4 dry cask containers (128 spent fuel assemblies) per year. At this rate, all spent fuel is estimated to be removed from the Comanche Peak site by 2095.
The NRC requires that licensees establish a program to manage and provide funding for the caretaking of all irradiated fuel at the reactor site until title of the fuel is transferred to the DOE.I141 Interim storage of the fuel, until the DOE has completed the transfer, will be in the fuel building's spent fuel storage pools, as well as at an on-site ISFSI.
An ISFSI, operated under a Part 50 General License (in accordance with 10 CFR 72, Subpart K[151), has been constructed at Comanche Peak to support continued plant operations. The facility is assumed to be expanded to support future decommissioning operations. Once the spent fuel storage pools are emptied the fuel building can be either decontaminated and dismantled or prepared for long term storage.
DOE has breached its obligations to remove fuel from reactor sites, and has also failed to provide CPPC with information about how it will ultimately perform. DOE officials have stated that DOE does not have an obligation to accept already-canistered fuel without an amendment to DOE's contracts with plant licensees to remove the fuel (the "Standard Contract"), but DOE has not explained what any such amendment would involve. Consequently, CPPC has no information or expectations on how DOE will remove fuel from the site in the future. In the absence of information about how DOE will perform, and for purposes of this analysis only, it is assumed that DOE will accept already-canistered fuel.
If this assumption is incorrect, it is assumed that DOE will have liability for costs incurred to transfer the fuel to DOE-supplied containers.
CPPC's position is that the DOE has a contractual obligation to accept the spent fuel earlier than the projections set out above consistent with its contract commitments. No assumption made in this study should be interpreted to be inconsistent with this claim. However, at this time, including the cost of storing spent fuel in this study is the most reasonable approach because it insures the availability of sufficient decommissioning funds at the end of the station's life if, contrary to its contractual obligation, the DOE has not performed earlier.

Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 1, Page 9 of 9 1.3.3 Radiological Criteria for License Termination In 1997, the NRC published Subpart E, "Radiological Criteria for License Termination,"[16] amending 10 CFR Part 20. This subpart provides radiological criteria for releasing a facility for unrestricted use. The regulation states that the site can be released for unrestricted use if radioactivity levels are such that the average member of a critical group would not receive a Total Effective Dose Equivalent (TEDE) in excess of 25 millirem per year, and provided that residual radioactivity has been reduced to levels that are As Low As Reasonably Achievable (ALARA).
The decommissioning estimates assume that the Comanche Peak 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).[17] An additional and separate limit of 4 millirem per year, as defined in 40 CFR
§141.66, is applied to drinking water.[181 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)['91 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 Detailed cost estimates were developed to decommission Comanche Peak based upon the approved decommissioning alternatives: DECON and SAFSTOR.
Two decommissioning scenarios were evaluated for Comanche Peak. The scenarios selected are representative of alternatives available to CPPC and are defined as follows:
- 1. The first scenario assumes that the units would be promptly decommissioned (DECON alternative) upon the expiration of the current operating licenses, i.e.,
2030 and 2033 for Units 1 and 2, respectively. Spent fuel in the wet storage pools would be relocated to the ISFSI for interim storage until such time that the DOE can complete the transfer, presumed to be in the year 2095.
- 2. In the second scenario, the nuclear units are placed into safe-storage (SAFSTOR alternative) at the end of their current operating licenses. Spent fuel in wet storage pools at that time would be relocated to the ISFSI for interim storage so as to minimize caretaking costs. The fuel would be transferred to the DOE (consistent with the assumptions in the DECON scenario) until the process is presumed to be complete in the year 2095. Decommissioning is deferred to the maximum extent (approximately 50 years) such that the property is released for unrestricted use within the generally required 60-year period (i.e., 2090 based upon the current Unit 1 shutdown date).
The following sections describe the basic activities associated with each alternative.
Although detailed procedures for each activity identified are not provided, and the actual sequence of work may vary, the activity descriptions provide a basis not only for estimating but also for the expected scope of work, i.e., engineering and planning at the time of decommissioning.
The conceptual approach that the NRC has described in its regulations divides decommissioning into three phases. The initial phase commences with the effective date of permanent cessation of operations and involves the transition of both plant and licensee from reactor operations (i.e., power production) to facility de-activation and closure. During the first phase, notification is to be provided to the NRC 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 Comanche Peak are also divided into phases or periods; however, TLG Services, Inc. 000034
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 2, Page 2 of 12 demarcation of the phases is based upon major milestones within the project or significant changes in the projected expenditures.
2.1 DECON The DECON alternative, as defined by the NRC, is "the alternative in which the equipment, structures, and portions of a facility and site containing radioactive contaminants are removed or decontaminated to a level that permits the property to be released for unrestricted use shortly after cessation of operations."
This study does not address the cost to dispose of the spent fuel residing at the site; such costs are funded through a surcharge on electrical generation.
However, the study does estimate the costs incurred with the interim on-site storage of the fuel pending shipment by the DOE to an off-site disposal facility.
2.1.1 Period 1 - Preparations In anticipation of the cessation of plant operations, detailed preparations are undertaken to provide a smooth transition from plant operations to site decommissioning. Through implementation of a staffing transition plan, the organization required to manage the intended decommissioning activities is assembled from available plant staff and outside resources.
Preparations include the planning for permanent defueling of the reactor, revision of technical specifications applicable to the operating conditions and requirements, a characterization of the facility and major components, and the development of the PSDAR.
Engineering and Planning The PSDAR provides a description of the licensee's planned decommissioning activities, a timetable, and the associated financial requirements of the intended decommissioning program. Upon receipt of the PSDAR, the NRC will make the document available to the public for comment in a local hearing to be held in the vicinity of the reactor site.
Ninety days 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, steam generators, and other large components that are radioactive. The NRC includes the following TLG Services, Inc. 000035
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 2, Page 3 of 12 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 licensee's existing license.
Existing operational technical specifications are reviewed and modified to reflect plant conditions and the safety concerns associated with permanent cessation of operations. The environmental impact associated with the planned decommissioning activities is also considered. Typically, a licensee will not be allowed to proceed if the consequences of a particular decommissioning activity are greater than that bounded by previously evaluated environmental assessments or impact statements. In this instance, the licensee would have to submit a license amendment for the specific activity and update the environmental report.
The decommissioning program outlined in the PSDAR will be designed to accomplish the required tasks within the ALARA guidelines (as defined in 10 CFR §20) for protection of personnel from exposure to radiation hazards. It will also address the continued protection of the health and safety of the public and the environment during the dismantling activity.
Consequently, with the development of the PSDAR, activity specifications, cost-benefit and safety analyses, and work packages and procedures, would be assembled to support the proposed decontamination and dismantling activities.
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 pools and fuel handling systems, such that decommissioning operations can commence on the balance of the plant. The pools will remain operational for approximately five and one half years following the cessation of Unit 2 operations. During TLG Services, Inc. 000036
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 2, Page 4 of 12 this time period, it is assumed that the spent fuel residing in the pools that cannot be directly transferred to the DOE will be moved to an ISFSI for interim storage.
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:
- 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) as required to facilitate hauling and transport. Modifications may be required to the containment structure to facilitate access of large/heavy equipment. Modifications may also be required to the refueling area of the building to support the segmentation of the reactor vessel internals and component extraction.
- Design and fabrication of temporary and permanent shielding to support removal and transportation activities, construction of contamination control envelopes, and the procurement of specialty tooling.
- Procurement (lease or purchase) of shipping canisters, cask liners, and industrial packages.
- Decontamination of components and piping systems as required to control (minimize) worker exposure.
TLG Services, Inc. 000037
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 2, Page 5 of 12
- Removal of piping and components no longer essential to support decommissioning operations.
- Removal of control rod drive housings and the head service structure from reactor vessel 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 baffle assembly, lower core barrel, and lower core plate. Some material is expected to exceed Class C disposal requirements. As such, the segments will be packaged in modified fuel storage canisters for geologic disposal.
Segmentation of the reactor vessel. A shielded platform is installed for segmentation as cutting operations are performed in-air using remotely operated equipment within a contamination control envelope. The water level is maintained just below the cut to minimize the working area dose rates. Segments are transferred in-air to containers that are stored under water, for example, in an isolated area of the refueling canal.
Removal of the activated portions of the concrete biological shield and accessible contaminated concrete surfaces. If dictated by the steam generator and pressurizer removal scenarios, those portions of the associated cubicles necessary for access and component extraction are removed.
Removal of the steam generators and pressurizer for material recovery and controlled disposal. The generators will be moved to an on-site processing center and the steam domes removed for transportation.
The steam domes, internal components, 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.
TLG Services, Inc. 000038
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 2, Page 6 of 12 At least two years prior to the anticipated date of license termination, a LTP is required. Submitted as a supplement to the Final Safety Analysis Report (FSAR) or its equivalent, the plan must include: a site characterization, description of the remaining dismantling activities, plans for site remediation, procedures for the final radiation survey, designation of the end use of the site, an updated cost estimate to complete the decommissioning, and any associated environmental concerns. The NRC will notice the receipt of the plan, make the plan available for public comment, and schedule a local hearing. LTP approval will be subject to any conditions and limitations as deemed appropriate by the NRC. The licensee may then commence with the final remediation of site facilities and services, including:
- Removal of remaining plant systems and associated components as they become nonessential to the decommissioning program or worker health and safety (e.g., waste collection and treatment systems, electrical power and ventilation systems).
- 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 auxiliary and 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 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 will facilitate 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 packaged for controlled disposal at the 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 TLG Services, Inc. 000039
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 2, Page 7 of 12 the "Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM)."[Zol This document incorporates the statistical approaches to survey design and data interpretation used by the EPA. It also identifies commercially available instrumentation and procedures for conducting radiological surveys. Use of this guidance ensures that the surveys are conducted in a manner that provides a high degree of confidence that applicable NRC criteria are satisfied. Once the survey is complete, the results are provided to the NRC in a format that can be verified. The NRC then reviews and evaluates the information, performs an independent confirmation of radiological site conditions, and makes a determination on the requested change to the operating licenses (that would release the property, exclusive of the ISFSI, 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 (exclusive of the ISFSI) is suitable for release.
2.1.3 Period 3 - Site Restoration Following completion of decommissioning operations, site restoration activities will begin. Efficient removal of the contaminated materials and verification that residual radionuclide concentrations are below the NRC limits will result in substantial damage to many of the structures.
Although performed in a controlled, safe manner, blasting, coring, drilling, scarification (surface removal), and the other decontamination activities will substantially degrade power block structures including the reactor, auxiliary, radwaste warehouse and fuel buildings. Under certain circumstances, verifying that subsurface radionuclide concentrations meet NRC site release requirements will require removal of grade slabs and lower floors, potentially weakening footings and structural supports.
This removal activity will be necessary for those facilities and plant areas where historical records, when available, indicate the potential for radionuclides having been present in the soil, where system failures have been recorded, or where it is required to confirm that subsurface process and drain lines were not breached over the operating life of the station.
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.
TLG Services, Inc. 000040
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 2, Page 8 of 12 This cost study presumes that non-essential structures and site facilities are dismantled as a continuation of the decommissioning activity.
Foundations and exterior walls are removed to a nominal depth of three feet below grade. The three-foot depth allows for the placement of gravel for drainage, as well as topsoil, so that vegetation can be established for erosion control. Site areas affected by the dismantling activities are restored and the plant area graded as required to prevent ponding and inhibit the refloating of subsurface materials.
Non-contaminated concrete rubble produced by demolition activities is processed to remove reinforcing steel and miscellaneous embedments.
The processed material is then used on site to backfill foundation voids.
Excess non-contaminated materials are trucked to an off-site area for disposal as construction debris.
2.1.4 ISFSI Operations and Decommissioning For purposes only of this estimate, transfer of spent fuel to a DOE repository or interim facility is assumed to be exclusively from the ISFSI.
If this assumption is incorrect, it is assumed that DOE will have liability for costs incurred to transfer the fuel to DOE-supplied containers and to dispose of existing containers. The ISFSI will continue to operate under a general license (10 CFR Part 50) following the amendment of the operating licenses to release the adjacent (power block) property.
Assuming the DOE starts accepting fuel from Comanche Peak in 2056, transfer of spent fuel from the ISFSI is anticipated to continue through the year 2095. This assumption is made for purposes of this estimate, although it is acknowledged that CPPC will seek the most expeditious means of removing fuel from the site when DOE commences performance.
At the conclusion of the spent fuel transfer process, the ISFSI will be decommissioned. The NRC will terminate the Part 50 license when it determines that the remediation of the ISFSI has been performed in accordance with an ISFSI license termination plan and that the final radiation survey and associated documentation demonstrate that the facility is suitable for release. Once the requirements are satisfied, the NRC can terminate the license for the ISFSI.
Spent fuel is stored on the ISFSI in multi-purpose canisters, with concrete overpacks. For purposes of this cost analysis, it is assumed that once the inner canisters containing the spent fuel assemblies have been removed, any required decontamination performed on the storage TLG Services, Inc. 000041
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 2, Page 9 of 12 overpack (some minor activation is assumed), and the license for the facility terminated, the concrete overpacks can be dismantled using conventional techniques for the demolition of reinforced concrete. The concrete storage pad is then removed and the area regraded to minimize ponding.
2.2 SAFSTOR The NRC defines SAFSTOR as "the alternative in which the nuclear facility is placed and maintained in a condition that allows the nuclear facility to be safely stored and subsequently decontaminated (deferred decontamination) to levels that permit release for unrestricted use." The facility is left intact (during the dormancy period), with structures maintained in a sound condition. Systems that are not required to support the spent fuel pools or site surveillance and security are drained, de-energized, and secured. Minimal cleaning/removal of loose contamination and/or fixation and sealing of remaining contamination is performed. Access to contaminated areas is secured to provide controlled access for inspection and maintenance.
The engineering and planning requirements are similar to those for the DECON alternative, although they are limited in scope with no large scale dismantling activities anticipated. Site preparations are also similar to those for the DECON alternative. However, with the exception of the required radiation surveys and site characterizations, the mobilization and preparation of site facilities is less extensive.
2.2.1 Period 1 - Preparations Preparations for long-term storage include the planning for permanent defueling of the reactor, revision of technical specifications appropriate to the operating conditions and requirements, a characterization of the facility and major components, and the development of the PSDAR.
The process of placing the station in safe-storage includes, but is not limited to, the following activities:
- Isolating of the spent fuel storage services and fuel handling systems so that safe-storage operations may commence on the balance of the plant. This activity may be carried out by plant personnel in accordance with existing operating technical specifications. Activities are scheduled around the fuel handling systems to the greatest extent possible.
TLG Services, Inc. 000042
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 2, Page 10 of 12
- Transferring of the spent fuel from the storage pools to the ISFSI for interim storage, following the minimum required cooling period in the spent fuel pools.
- Draining and de-energizing of the non-contaminated systems not required to support continued site operations or maintenance.
- Disposing of contaminated filter elements and resin beds not required for processing wastes from layup activities for future operations.
- Draining of the reactor vessel, with the internals left in place and the vessel head secured.
- Draining and de-energizing non-essential, contaminated systems with decontamination as required for future maintenance and inspection.
- Preparing lighting and alarm systems whose continued use is required; de-energizing portions of fire protection, electric power, and HVAC systems whose continued use is not required.
- Cleaning of the loose surface contamination from building access pathways.
- Performing an interim radiation survey of the 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 alternatives. Dormancy activities include a 24-hour security force, preventive and corrective maintenance on security systems, area lighting, general building maintenance, heating and ventilation of buildings, routine radiological inspections of contaminated structures, maintenance of structural integrity, and a site environmental and radiation monitoring program. Site 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.
TLG Services, Inc. 000043
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 2, Page 11 of 12 An environmental surveillance program is carried out during the dormancy period to ensure that releases of radioactive material to the environment are prevented and/or detected and controlled. Appropriate emergency procedures are established and initiated for potential releases that exceed prescribed limits. The environmental surveillance program constitutes an abbreviated version of the program in effect during normal plant operations.
Security during the dormancy period is conducted primarily to prevent unauthorized entry and to protect the public from the consequences of its own actions. The security fence, sensors, alarms, and other surveillance equipment provide security. Fire and radiation alarms are also monitored and maintained.
Consistent with the DECON alternative, the spent fuel storage pools are emptied within five and one half years of the cessation of operations. The transfer of the spent fuel to the DOE begins during the dormancy period in year 2056 and continues throughout (and beyond) the delayed decommissioning phase.
After a period of storage (such that license termination is accomplished within 60 years of the cessation of Unit 1 operations), 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.
TLG Services, Inc. 000044
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 2, Page 12 of 12 Variations in the length of the dormancy period are expected to have some effect upon the quantities of radioactive wastes generated from system and structure removal operations. Given the levels of radioactivity and spectrum of radionuclides expected from forty years of plant operation, no plant process system identified as being contaminated upon final shutdown will become releasable due to the decay period alone. The delay in decommissioning yields lower working area radiation levels. As such, the estimates for this delayed scenario incorporate reduced ALARA controls for the SAFSTOR's lower occupational exposure potential.
Although the initial radiation levels due to 60Co will decrease during the dormancy period, the internal components of the reactor vessel will still exhibit sufficiently high radiation dose rates to require remote sectioning under water due to the presence of long-lived radionuclides such as 94Nb, 59 Ni, and 63Ni. Therefore, the dismantling procedures described for the DECON alternative would still be employed during this scenario. Portions of the biological shield wall will still be radioactive due to the presence of activated trace elements with long half-lives (152Eu and 154Eu).
Decontamination will require controlled removal and disposal. It is assumed that radioactive corrosion products on inner surfaces of piping and components will not have decayed to levels that will permit unrestricted use or allow conventional removal. These systems and components will be surveyed as they are removed and disposed of in accordance with the existing radioactive release criteria.
2.2.4 Period 5 - Site Restoration Following completion of decommissioning operations, site-restoration activities can begin. Dismantling, as a continuation of the decommissioning process, is clearly the most appropriate and cost-effective option, as described in Section 2.1.3. The basis for the dismantling cost in this scenario is consistent with that described for DECON, presuming the removal of structures and site facilities to a nominal depth of three feet below grade and the limited restoration of the site.
2.2.5 ISFSI Operations and Decommissioning Completion of the spent fuel transfer operations is currently assumed to be in year 2095. Once complete, the ISFSI will be decommissioned as described in Section 2.1.4.

- 3. COST ESTIMATE The cost estimates prepared for decommissioning Comanche Peak consider the unique features of the site, including the NSSS, power generation systems, support services, site buildings, and ancillary facilities. The basis of the estimates, including the sources of information relied upon, the estimating methodology employed, site-specific considerations, and other pertinent assumptions, is described in this section.
3.1 BASIS OF ESTIMATE The estimates were developed using the site-specific, technical information from the 2014 analysis. This information was reviewed for the current analysis and updated as deemed appropriate. The site-specific considerations and assumptions used in the previous evaluation were also revisited. Modifications were incorporated where new information was available or experience from ongoing decommissioning programs provided viable alternatives or improved processes.
3.2 METHODOLOGY The methodology used to develop the estimates follows the basic approach originally presented in the AIF/NESP-036 study report, "Guidelines for Producing Commercial Nuclear Power Plant Decommissioning Cost Estimates,"[21] and the DOE "Decommissioning Handbook."[22] 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. When specific CP information was not available, quantities were taken from information for a similar plant. Removal rates and material costs for the conventional disposition of components and structures rely upon information available in the industry publication, "Building Construction Cost Data," published by RSMeans.[23]
The unit factor method provides a demonstrable basis for establishing reliable cost estimates. The detail provided in the unit factors, including activity duration, labor costs (by craft), and equipment and consumable costs, ensures that essential elements have not been omitted. Appendix A presents the detailed development of a typical unit factor. Appendix B provides the values contained within one set of factors developed for this analysis.
TLG Services, Inc. 000046
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 2 of 60 Regulatory Guide 1.184[241 Revision 1, issued in October 2013, describes the methods and procedures that are acceptable to the NRC staff for implementing 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 1.202,1251 issued February 2005.
This analysis reflects lessons learned from TLG's involvement in the Shippingport Station Decommissioning Project, completed in 1989, as well as the decommissioning of the Cintichem reactor, hot cells, and associated facilities, completed in 1997. In addition, the planning and engineering for the 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.
Work Difficulty Factors TLG has historically applied work difficulty adjustment factors (WDFs) to account for the inefficiencies in working in a power plant environment. WDFs are assigned to each unique set of unit factors, commensurate with the inefficiencies associated with working in confined, hazardous environments.
The ranges used for the WDFs are as follows:
- Access Factor 10% to 20%
- Respiratory Protection Factor 10% to 50%
- Radiation/ALARA Factor 10% to 37%
- Protective Clothing Factor 10% to 30%
- Work Break Factor 8.33%
The factors and their associated range of values were developed in conjunction with the AIF/NESP-036 study. The application of the factors is discussed in more detail in that publication.
Scheduling Program Durations The unit factors, adjusted by the WDFs as described above, are applied against the inventory of materials to be removed in the radiological controlled areas. The resulting man-hours, or crew-hours, are used in the development of the TLG Services, Inc. 000047
Comanche Peak Nuclear Power Plant Document LH-1774-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 3 of 60 decommissioning program schedule, using resource loading and event sequencing considerations. The scheduling of conventional removal and dismantling activities is based upon productivity information available from the "Building Construction Cost Data" publication. In the DECON alternative, dismantling of the fuel building systems and decontamination of the spent fuel pools are also dependent upon the timetable for the transfer of the spent fuel assemblies from the pools to the ISFSI.
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 IMPACT OF DECOMMISSIONING MULTIPLE REACTOR UNITS In estimating the near simultaneous decommissioning of two co-located reactor units there can be opportunities to achieve economies of scale, by sharing costs between units, and coordinating the sequence of work activities. There will also be schedule constraints, particularly where there are requirements for specialty equipment and staff, or practical limitations on when final status surveys can take place. For purposes of the estimates, Units 1 and 2 are assumed to be essentially identical. Common facilities have been assigned to Unit 2. A summary of the principal impacts is listed below.
- The sequence of work generally follows the principal that the work is done at Unit 1 first, followed by similar work at Unit 2. This permits the experience gained at Unit 1 to be applied by the workforce at the second unit. It should be noted however, that the estimates do not consider productivity improvements at the second unit, since there is little documented experience with decommissioning two units simultaneously. The work associated with developing activity specifications and procedures can be considered essentially identical between the two units, therefore the second unit costs are assumed to be a fraction of the first unit ( 43%).
- Segmenting the reactor vessel and internals will require the use of special equipment. The decommissioning project will be scheduled such that Unit 2's reactor internals and vessel are segmented after the activities at Unit 1 have been completed.
- Some program management and support costs, particularly costs associated with the more senior positions, can be avoided with two reactors undergoing decommissioning simultaneously. As a result, the estimates are based on a TLG Services, Inc. 000048
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 4 of 60 "lead" unit that includes these senior positions, and a "second" unit that excludes these positions. The designation as lead is based on the unit undertaking the most complex tasks (for instance vessel segmentation) or performing tasks for the first time.
- The final radiological survey schedule is also affected by a two-unit decommissioning schedule. It would be considered impractical to try to complete the final status survey of Unit 1, while Unit 2 still has ongoing radiological remediation work and waste handling in process. As such, the transfer of the spent fuel from the storage pools and subsequent decontamination of the fuel building is coordinated so as to synchronize the final status survey for the station.
- The final demolition of buildings at Units 1 and 2 are considered to take place concurrently. This is considered a reasonable assumption since access to the buildings is considered good at the station.
- Unit 1, as the first unit to enter decommissioning, incurs the majority of site characterization costs.
- Shared systems and structures are generally assigned to Unit 2.
- Station costs such as emergency response fees, regulatory agency fees, corporate overhead, and insurance are generally allocated on an equal basis between the two units.
3.4 FINANCIAL COMPONENTS OF THE COST MODEL TLG's proprietary decommissioning cost model, DECCER, produces a number of distinct cost elements. These direct expenditures, however, do not comprise the total cost to accomplish the project goal, i.e., license termination and site restoration.
Inherent in any cost estimate that does not rely on historical data is the inability to specify the precise source of costs imposed by factors such as tool breakage, accidents, illnesses, weather delays, and labor stoppages. In the DECCER cost model, contingency fulfills this role. Contingency is added to each line item to account for costs that are difficult or impossible to develop analytically. Such costs are historically inevitable over the duration of a job of this magnitude; therefore, this cost analysis includes funds to cover these types of expenses.
TLG Services, Inc. 000049
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 5 of 60 3.4.1 Contingency The activity- and period-dependent costs are combined to develop the total decommissioning cost. A contingency is then applied on a line-item basis, using one or more of the contingency types listed in the AIF/NESP -036 study. "Contingencies" are defined in the American Association of Cost Engineers "Project and Cost Engineers' Handbook"[261 as "specific provision for unforeseeable elements of cost within the defined project scope; particularly important where previous experience relating estimates and actual costs has shown that unforeseeable events which will increase costs are likely to occur." The cost elements in this analysis are based upon ideal conditions and maximum efficiency; therefore, consistent with industry practice, contingency is included. In the AIF/NESP-036 study, the types of unforeseeable events that are likely to occur in decommissioning are discussed and guidelines are provided for percentage contingency in each category. It should be noted that contingency, as used in this analysis, does not account for price escalation and inflation in the cost of decommissioning over the remaining operating life of the station.
Contingency funds are an integral part of the total cost to complete the decommissioning process. Exclusion of this component puts at risk a successful completion of the intended tasks and, potentially, subsequent related activities. For this study, TLG examined the major activity-related problems (decontamination, segmentation, equipment handling, packaging, transport, and waste disposal) that necessitate a contingency.
Individual activity contingencies ranged from 10% to 75%, depending on the degree of difficulty judged to be appropriate from TLG's actual decommissioning experience. The contingency values used in this study are as follows:
- Decontamination 50%
- Contaminated Component Removal 25%
- Contaminated Component Packaging 10%
- Contaminated Component Transport 15%
- Low-Level Radioactive Waste Disposal 25%
- Reactor Segmentation 75%
- NSSS Component Removal 25%
- Reactor Waste Packaging 25%
- Reactor Waste Transport 25%
- Reactor Vessel Component Disposal 50%
TLG Services, Inc. 000050
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 6 of 60
- GTCC Disposal 15%
- Non-Radioactive Component Removal 15%
- Heavy Equipment and Tooling 15%
- Supplies 25%
- Engineering 15%
- E nergy 15%
- Characterization and Termination Surveys 30%
- Construction 15%
- Taxes and Fees 10%
- Insurance 10%
- Staffing 15%
- Spent Fuel Storage (Dry) Systems 15%
- Spent Fuel Transfer Costs 15%
- Operations and Maintenance Expenses 15%
- ISFSI Decommissioning 25%
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 and D). A contingency of 25% is applied to the subtotal of the ISFSI decommissioning costs in Appendix E.
3.4.2 Financial Risk In addition to the routine uncertainties addressed by contingency, another cost element that is sometimes necessary to consider when bounding decommissioning costs relates to uncertainty, or risk. Examples can include changes in work scope, pricing, job performance, and other variations that could conceivably, but not necessarily, occur.
Consideration is sometimes necessary to generate a level of confidence in the estimate, within a range of probabilities. TLG considers these types of costs under the broad term "financial risk." Included within the category of financial risk are:
- Transition activities and costs: ancillary expenses associated with outplacement of 50% to 80% of the site labor force shortly after the cessation of plant operations, added cost for national or company-mandated retraining, and retention incentives for key personnel.
TLG Services, Inc. 000051
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 7 of 60
- Delays in approval of the decommissioning plan due to intervention, public participation in local community meetings, legal challenges, and national and local hearings.
- Changes in the project work scope from the baseline estimate, involving the discovery of unexpected levels of contaminants, contamination in places not previously expected, contaminated soil previously undiscovered (either radioactive or hazardous material contamination), variations in plant inventory or configuration not indicated by the as-built drawings.
- Regulatory changes, for example, affecting worker health and safety, site release criteria, waste transportation, and disposal.
- Policy decisions altering national commitments (e.g., in the ability to accommodate certain waste forms for disposition), or in the timetable for such, for example, the start and rate of acceptance of spent fuel by the DOE.
- Pricing changes for basic inputs such as labor, energy, materials, and disposal. Items subject to widespread price competition (such as materials) may not show significant variation; however, others such as waste disposal could exhibit large pricing uncertainties, particularly in markets where limited access to services is available.
This cost study does not add any additional costs to the estimate for financial risk, since there is insufficient historical data from which to project future liabilities. Consequently, the areas of uncertainty or risk are revisited periodically and addressed through repeated revisions or updates of the base estimates (e.g., in accordance with Regulatory Guide 1.159).
3.5 SITE-SPECIFIC CONSIDERATIONS There are a number of site-specific considerations that affect the method for dismantling and removal of equipment from the site and the degree of restoration required. The cost impact of the considerations identified below is included in this cost study.
3.5.1 Spent Fuel Management The cost to dispose the spent fuel generated from plant operations is not reflected within the estimates to decommission Comanche Peak. Ultimate disposition of the spent fuel is within the province of the DOE's Waste Management System, as defined by the Nuclear Waste Policy Act. As TLG Services, Inc. 000052
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 8 of 60 such, the disposal cost is financed by a surcharge paid into the DOE's waste fund during operations. On November 19, 2013, the U.S. Court of Appeals for the D.C. Circuit ordered the Secretary of the Department of Energy to suspend collecting annual fees for nuclear waste disposal from nuclear power plant operators until the DOE has conducted a legally adequate fee assessment.
The NRC does, however, require licensees to establish a program to manage and provide funding for the management of all irradiated fuel at the reactor site until title of the fuel is transferred to the Secretary of Energy. This requirement is prepared for through inclusion of certain high-level waste cost elements within the estimates, as described below.
Completion of the decommissioning process is dependent upon the DOE's ability to remove spent fuel from the site in a timely manner. DOE's repository program assumes that spent fuel allocations will be accepted for disposal from the nation's commercial nuclear plants, with limited exceptions, in the order (the "queue") in which it was discharged from the reactor. CPPC's current spent fuel management plan for the Comanche Peak spent fuel is based in general upon: 1) a 2056 start date for DOE initiating transfer of Comanche Peak spent fuel to a federal facility (not necessarily a final repository), and 2) a spent fuel transfer 2095 completion date. The management of the spent fuel inventory is delineated in Table 3.1. Different DOE acceptance assumptions would result in different completion dates.
ISFSI An ISFSI pad has been constructed at Comanche Peak to hold 84 storage casks (overpacks). The ISFSI was licensed by the NRC under the general license provisions of 10 CFR Part 72. The first cask was placed on the ISFSI pad on February 28, 2012.
Assuming that the DOE doesn't start accepting spent fuel until 2055; Comanche Peak will need to construct a second pad to accommodate the entire inventory of spent fuel discharged over the reactors' operating life.
Construction of a second pad is included within the estimates. Post-shutdown and maintenance costs for the ISFSI pads are also included and address the cost for staffing the facilities, as well as security, insurance, and licensing fees. Costs are provided for the final disposition of the pads once the transfer is complete.
TLG Services, Inc. 000053
Comanche Peak Nuclear Pozver Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 9 of 60 Canister Design The design and capacity of the ISFSI is based upon the HOLTEC HI-STORM 100S Version B dry storage system. The system consists of a multi-purpose canister (MPC) with a nominal capacity of 32 fuel assemblies and a concrete storage overpack.
Canister Loading and Transfer The estimates include the cost for the labor and equipment to load and transfer each spent fuel canister to the ISFSI. For estimating purposes, an allowance is used for the cost to transfer the fuel from the ISFSI into the DOE transport cask.
Since the DOE has not published details about its cask system, this rough estimate is necessary. However, use of this estimate should not be used to infer that TLG has any detailed information on the cask system DOE will ultimately provide.
Operations and Maintenance The estimates include the cost of operating and maintaining the spent fuel pools and the ISFSI, respectively. Pool operations are expected to continue approximately five and one half years after the cessation of Unit 2 operations. ISFSI operating costs are based upon a 2095 end date for spent fuel transfer.
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 should contain sufficient information on the proposed practices and procedures for the decontamination of the ISFSI and for the disposal of residual radioactive materials after all spent fuel, high-level radioactive waste, and reactor-related GTCC waste have been removed.
The storage overpacks are assumed to have some level of neutron-induced activation, as a result of the long-term storage of the fuel, i.e., to levels exceeding free-release limits. As an allowance, 14 overpacks are assumed to require remediation, equivalent to the number of overpacks required to accommodate the final core off load from both units. The cost of the TLG Services, Inc. 000054
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 10 of 60 disposition of this material, as well as the demolition of the ISFSI facility, is included in the estimates.
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. The cost summary for decommissioning the ISFSI is presented in Appendix E.
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 Greater than Class C or GTCC). The Low-Level Radioactive Waste Policy Amendments Act of 1985 assigned the federal government the responsibility for the disposal of this material. The Act also stated that the beneficiaries of the activities resulting in the generation of such radioactive waste bear all reasonable costs of disposing of such waste.
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 constraints on loading as identified in the canister's certificate of compliance).
It is assumed only for purposes of these estimates that the DOE would not accept this waste prior to completing the transfer of spent fuel. Therefore, until such time as the DOE is ready to accept GTCC waste, it is assumed that this material would remain in storage at the Comanche Peak site. It is acknowledged, however, that CPPC will seek the most expeditious means of removing the GTCC from the site when DOE commences performance.
3.5.2 Reactor Vessel and Internal Components The reactor pressure vessel and internal components are segmented for disposal in shielded, reusable transportation casks. Segmentation is performed in the refueling canal, where a turntable and remote cutter are TLG Services, Inc. 000055
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 11 of 60 installed. The vessel is segmented in place, using a mast-mounted cutter supported off the lower head and directed from a shielded work platform installed overhead in the reactor cavity. Transportation cask specifications and transportation regulations dictate the segmentation and packaging methodology.
Intact disposal of reactor vessel shells has been successfully demonstrated at several of the sites that have been decommissioned. Access to navigable waterways has allowed these large packages to be transported to the Barnwell disposal site with minimal overland travel. Intact disposal of the reactor vessel and internal components can provide savings in cost and worker exposure by eliminating the complex segmentation requirements, isolation of the GTCC material, and transport/storage of the resulting waste packages. Portland General Electric (PGE) was able to dispose of the Trojan reactor as an intact package (including the internals).
However, its location on the Columbia River simplified the transportation analysis since:
- the reactor package could be secured to the transport vehicle for the entire journey, i.e., the package was not lifted during transport,
- there were no man-made or natural terrain features between the plant site and the disposal location that could produce a large drop, and
- transport speeds were very low, limited by the overland transport vehicle and the river barge.
As a member of the Northwest Compact, PGE had a site available for disposal of the package - the US Ecology facility in Washington State. The characteristics of this arid site proved favorable in demonstrating compliance with land disposal regulations.
It is not known whether this option will be available when the Comanche Peak plant ceases operation. Future viability of this option will depend upon the ultimate location of the disposal site, as well as the disposal site licensee's ability to accept highly radioactive packages and effectively isolate them from the environment. Consequently, the study assumes that the reactor vessel will require segmentation, as a bounding condition.

Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 12 of 60 3.5.3 Primary System Components In the DECON alternative, the reactor coolant system components are assumed to be decontaminated using chemical agents prior to the start of dismantling operations. This type of decontamination can be expected to have a significant ALARA impact, since in this scenario the removal work is done within the first few years of shutdown. A decontamination factor (average reduction) of 10 is assumed for the process. Disposal of the decontamination solution effluent is included within the estimate as a "process liquid waste" charge. In the SAFSTOR alternative, radionuclide decay is expected to provide the same benefit and, therefore, a chemical decontamination is not included.
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 disposal.
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 Containment Building to a location where they can be decontaminated and transported to the material handling area.
Interferences within the work area, such as grating, piping, and other components are removed to create sufficient laydown space for processing these large components.
The generators are rigged for removal, disconnected from the surrounding piping and supports, and maneuvered into the open area where they are lowered onto a dolly. Each generator is rotated into the horizontal position for extraction from the containment and placed onto a multi-wheeled vehicle for transport to an on-site processing and storage area.
TLG Services, Inc. 000057
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 13 of 60 The generators are disassembled on-site for transport to the disposal site.
The interior volume is filled with low-density cellular concrete for stabilization of the internal contamination.
Each component is then loaded onto a rail car for transport to the disposal facility.
3.5.4 Main Turbine and Condenser The main turbine is dismantled using conventional maintenance procedures. The turbine rotors and shafts are removed to a laydown area.
The lower turbine casings are removed from their anchors by controlled demolition. The main condensers are also disassembled and moved to a laydown area. Material is then prepared for transportation to an off-site recycling facility where it is surveyed and designated for either decontamination or volume reduction, conventional disposal, or controlled disposal. Components are packaged and readied for transport in accordance with the intended disposition.
3.5.5 Retired Components The estimates include the disposition, from Unit 1, of four retired steam generators and a retired reactor vessel closure head. The components, currently in storage at the site, will be prepared for transport and disposal. Similar to the disposition of the operating units, the steam domes of the generators are assumed to be removed to meet transport clearances. The estimates for the retired components include the project management, contractor and supporting costs necessary to execute the tasks assuming that the disposition would be a coordinated effort (i.e.,
single mobilization effort).
The estimates also include the disposition of one high-pressure and two low-pressure turbine rotors as clean scrap.
3.5.6 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.[27] The contaminated material will be packaged in Industrial Packages (IP-1, IP-2, or IP-3, as defined in subpart 10 CFR 173.411) for transport unless demonstrated to qualify as their own shipping containers. The reactor vessel and internal components are TLG Services, Inc. 000058
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 14 of 60 expected to be transported in accordance with Part 71, as Type B containers. 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 material requiring controlled disposal are based upon the route and mileage to the Andrews County facility in western Texas. Truck transport costs are estimated using published tariffs from Tri-State Motor Transit.[281 3.5.7 Low-Level Radioactive Waste Disposal The mass of radioactive waste generated during the various decommissioning activities at the site is shown on a line-item basis in the detailed Appendices C and D, and summarized in Section 5. The quantified waste summaries shown in these tables are consistent with 10 CFR Part 61 classifications. Commercially available steel containers are presumed to be used for the disposal of piping, small components, and concrete. Larger components can serve as their own containers, with proper closure of all openings, access ways, and penetrations. The volumes are calculated based on the exterior package dimensions for TLG Services, Inc. 000059
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 15 of 60 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. 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 low-level radioactive material generated from the decontamination and dismantling activities is based upon CPPC's current cost for disposal at the Texas Compact facility operated by Waste Control Specialists in Andrews County.
3.5.8 Site Conditions Following Decommissioning The NRC will terminate the site license if it determines that site remediation has been performed in accordance with the license termination plan, and that the terminal radiation survey and associated documentation demonstrate that the facility is suitable for release. The NRC's involvement in the decommissioning process will end at this point.
Building codes and environmental regulations will dictate the next step in the decommissioning process, as well as CPPC's own future plans for the site.
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 four 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.
Only existing site structures are considered in the dismantling cost. The existing electrical switchyard and access roads will remain in support of the electrical transmission and distribution system. The site access road will be left intact.
Structures are removed to a nominal depth of three feet below grade.
Concrete rubble generated from demolition activities is processed and made available as clean fill for the power block foundations. Additional fill is brought in to cap the power block excavations and to permit seeding for erosion control.

Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 16 of 60 3.6 ASSUMPTIONS The following are the major assumptions made in the development of the estimates for decommissioning the site.
3.6.1 Estimating Basis Decommissioning costs are reported in the year of projected expenditure; however, the values are provided in 2019 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 2014 analysis, with an adjustment to include the subsequent addition of the Stator Rewind Building.
The study follows the principles of ALARA through the use of work duration adjustment factors. These factors address the impact of activities such as radiological protection instruction, mock-up training, and the use of respiratory protection and protective clothing. The factors lengthen a task's duration, increasing costs and lengthening the overall schedule.
ALARA planning is considered in the costs for engineering and planning, and in the development of activity specifications and detailed procedures.
Changes to worker exposure limits may impact the decommissioning cost and project schedule.
3.6.2 Labor Costs CPPC will hire a Decommissioning Operations Contractor (DOC) to manage the decommissioning. CPPC will provide site security, radiological health and safety, quality assurance and overall site administration during the decommissioning and demolition phases. Costs for site administration, operations, construction, and maintenance personnel are based upon average salary information provided by CPPC.
Contract personnel will provide engineering services, e.g., for preparing the activity specifications, work procedures, activation, and structural analyses, under the direction of CPPC.
The craft labor required to decontaminate and dismantle the nuclear units will be acquired through standard site contracting practices. The current cost of labor at the site is used as an estimating basis.
TLG Services, Inc. 000061
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 17 of 60 Reductions in the operating organization are handled through normal company practices. No costs have been included for this activity.
Severance costs are included for the decommissioning staff as the organization is downsized.
Security, while reduced from operating levels, is maintained throughout the decommissioning for access control, material control, and to safeguard the spent fuel (in accordance with the requirements of 10 CFR Part 37, Part 72, and Part 73). Security costs include provisions for recurring expenses.
3.6.3 Design Conditions Any fuel cladding failure that occurred during the lifetime of the plant is assumed to have released fission products at sufficiently low levels that the buildup of quantities of long-lived isotopes (e.g., 137Cs, 905r, or transuranics) has been prevented from reaching levels exceeding those that permit the major NSSS components to be shipped under current transportation regulations and disposal requirements.
The curie contents of the vessel and internals at final shutdown are derived from those listed in NUREG/CR-3474.[291 Actual estimates are derived from the curie/gram values contained therein and adjusted for the different mass of the Comanche Peak components, projected operating life, and different periods of decay. Additional short-lived isotopes were derived from NUREG/CR-0130[3°] and NUREG/CR-0672, [31] and benchmarked to the long-lived values from NUREG/CR-3474.
The control elements are disposed of along with the spent fuel, i.e., there is no additional cost provided for their disposal. Activation of the containment building structure is confined to the biological shield.
3.6.4 General Transition Activities Existing warehouses are cleared of non-essential material and remain for use by CPPC and its subcontractors. The plant's operating staff performs the following activities at no additional cost or credit to the project during the transition period:
- Drain and collect fuel oils, lubricating oils, and transformer oils for recycle and/or sale.
TLG Services, Inc. 000062
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 18 of 60
- 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. CPPC will make economically reasonable efforts to salvage equipment following final plant shutdown. However, dismantling techniques assumed by TLG for equipment in this analysis are not consistent with removal techniques required for salvage (resale) of equipment. Experience has indicated that some buyers wanted equipment stripped down to very specific requirements before they would consider purchase. This required expensive rework after the equipment had been removed from its installed location. Since placing a salvage value on this machinery and equipment would be speculative, and the value would be small in comparison to the overall decommissioning expenses, this analysis does not attempt to quantify the value that an owner may realize based upon those efforts.
It is assumed, for purposes of this analysis, that any value received from the sale of scrap generated in the dismantling process would be more than offset by the on-site processing costs. The dismantling techniques assumed in the decommissioning estimates do not include the additional cost for size reduction and preparation to meet "furnace ready" conditions.
For example, the recovery of copper from electrical cabling may require the removal and disposition of any contaminated insulation, an added expense. With a volatile market, the potential profit margin in scrap recovery is highly speculative, regardless of the ability to free release this material. This assumption is an implicit recognition of scrap value in the disposal of clean metallic waste at no additional cost to the project.
Furniture, tools, mobile equipment such as forklifts, trucks, bulldozers, and other property are 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 TLG Services, Inc. 000063
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 19 of 60 power costs are used to calculate the cost of energy consumed during decommissioning for tooling, lighting, ventilation, and essential services.
Emergency Planning FEMA and state fees associated with emergency planning are assumed to continue for approximately 18 months following the cessation of operations. At this time, the fees are discontinued. The timing is based upon the anticipated condition of the spent fuel (i.e., the hottest spent fuel assemblies are assumed to be cool enough that no substantial Zircaloy oxidation and off-site event would occur with the loss of spent fuel pools water). State fees continue until all fuel has been moved from the pools into dry storage (approximately five and one-half years following the cessation of operations).
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.132] The NRC's financial protection requirements are based on various reactor (and spent fuel) configurations.
Taxes Property taxes are included within the estimates. However, the tax is based upon the land, without any consideration of any ongoing site operations and property assets.
Site Modifications The perimeter fence and in-plant security barriers will be moved, as appropriate, to conform to the Site Security Plan in force during the various stages of the project.
Site Restoration All structures will be removed except for the switchyard. The switchyard is required for grid operations. Structures to be removed include but are not limited to the reactor, fuel, auxiliary, radwaste warehouse, safeguard, diesel generator, and turbine buildings.

Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 20 of 60 3.7 COST ESTIMATE
SUMMARY
Schedules of expenditures are provided in Tables 3.2 through 3.5. The tables delineate the cost contributors by year of expenditures as well as cost contributor (e.g., labor, materials, and waste disposal).
Additional tables in Appendices C and D provide detailed cost elements. The cost elements are also assigned to one of three subcategories: "License Termination,"
"Spent Fuel Management," and "Site Restoration." The subcategory "License Termination" is used to accumulate costs that are consistent with "decommissioning" as defined by the NRC in its financial assurance regulations (i.e., 10 CFR §50.75). The cost reported for this subcategory is generally sufficient to terminate the plant's operating license, recognizing that there may be some additional cost impact from spent fuel management. This subcategory also includes the costs of disposing of the following Unit 1 components: the retired steam generators, the reactor vessel closure head, and spare high and low pressure turbine rotors. The study assumes that the disposal of the components would occur after shutdown, however, the costs are identified separately because the disposal activities could be conducted at any time.
The License Termination cost subcategory also includes costs to decommission the ISFSI (as required by 10 CFR §72.30). The basis for the ISFSI decommissioning cost that is included in both Appendices C and D is provided in Appendix E.
The "Spent Fuel Management" subcategory contains costs anticipated to be incurred once the nuclear units cease operation for the off-loading of the pools to the ISFSI for interim storage, and the eventual transfer of the fuel from the ISFSI to the DOE. Costs are also included for the operation of the ISFSI until such time that the transfer of all fuel from this facility to an off-site location (e.g.,
geologic repository) is complete.
"Site Restoration" is used to capture costs associated with the dismantling and demolition of buildings and facilities demonstrated to be free from contamination. This includes structures never exposed to radioactive materials, as well as those facilities that have been decontaminated to appropriate levels.
Structures are removed to a depth of three feet and backfilled to conform to local grade.
As discussed in Section 3.5.1, it is not anticipated that the DOE will accept the GTCC waste prior to completing the transfer of spent fuel. Therefore, the cost of GTCC disposal is shown in the final year of ISFSI operation. While designated for disposal at the geologic repository along with the spent fuel, GTCC waste is TLG Services, Inc. 000065
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 3, Page 21 of 60 still classified as low-level radioactive waste and, as such, included as a "License Termination" expense.
Decommissioning costs are reported in 2019 dollars. Costs are not inflated, escalated, or discounted over the period of expenditure (or projected lifetime of the plant). The schedules are based upon the detailed activity costs reported in Appendices C and D, along with the timeline presented in Section 4.

- 4. SCHEDULE ESTIMATE The schedules for the decommissioning scenarios considered in this study follow the sequences presented in the AIF/NESP-036 study, with minor changes to reflect recent experience and site-specific constraints. In addition, the scheduling has been revised to reflect the spent fuel management plan described in Section 3.5.1.
A schedule or sequence of activities for the DECON alternative is presented in Figure 4.1. The scheduling sequence is based on the fuel being removed from the spent fuel pools within five and one half years. The key activities listed in the schedule do not reflect a one-to-one correspondence with those activities in the cost tables, but reflect dividing some activities for clarity and combining others for convenience. The schedule was prepared using the "Microsoft Project Professional" computer software.[331 4.1 SCHEDULE ESTIMATE ASSUMPTIONS The schedule reflects the results of a precedence network developed for the site decommissioning activities, i.e., a PERT (Program Evaluation and Review Technique) Software Package. The work activity durations used in the precedence network reflect the actual man-hour estimates from the cost table, adjusted by stretching certain activities over their slack range and shifting the start and end dates of others. The following assumptions were made in the development of the decommissioning schedule:
- The fuel building is isolated until such time that all spent fuel has been discharged from the spent fuel pools to the ISFSI for interim storage.
Decontamination and dismantling of the storage pools is initiated once the transfer of spent fuel is complete (DECON alternative).
- All work (except vessel and internals removal) is performed during an 8-hour workday, 5 days per week, with no overtime. There are eleven paid holidays per year.
- Reactor and internals removal activities are performed by using separate crews for different activities working on different shifts, with a corresponding backshift charge for the second shift.
- Multiple crews work parallel activities to the maximum extent possible, consistent with optimum efficiency, adequate access for cutting, removal and laydown space, and with the stringent safety measures necessary during demolition of heavy components and structures.

Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 4, Page 2 of 6 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 the 2030 and 2033 shutdown dates for Units 1 and 2, respectively. The fuel pools are emptied approximately five and one half years after Unit 2 shutdown, while ISFSI operations continue until the DOE can complete the transfer of assemblies.
Deferred decommissioning in the SAFSTOR alternative is assumed to commence so that the site can be released for alternative use, excluding the ISFSI, 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,[34] 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 are shown on a line-item basis in Appendices C and D and summarized in Tables 5.1 and 5.2. The volumes are calculated based on the exterior dimensions for containerized material and on the displaced volume of components serving as their own waste containers.
The reactor vessel and internals are categorized as large quantity shipments and, accordingly, will be shipped in reusable, shielded truck casks with disposable liners.
In calculating disposal costs, the burial fees are applied against the liner volume, as well as the special handling requirements of the payload. Packaging efficiencies are lower for the highly activated materials (greater than Type A quantity waste), where high concentrations of gamma-emitting radionuclides limit the capacity of the shipping canisters.
No process system containing/handling radioactive substances at shutdown is presumed to meet material release criteria by decay alone (i.e., systems radioactive at shutdown will still be radioactive over the time period during which the decommissioning is accomplished, due to the presence of long-lived radionuclides).
While the dose rates decrease with time, radionuclides such as 137Cs will still control the disposition requirements.

- 6. RESULTS The analysis to estimate the costs to decommission Comanche Peak relied upon the site-specific, technical information developed for a previous analysis prepared in 2014, updated to reflect current assumptions pertaining to the disposition of the nuclear station and relevant industry experience in undertaking such projects. While not an engineering study, the estimates provide CPPC with sufficient information to assess their financial obligations, as they pertain to the eventual decommissioning of the nuclear station.
The estimates described in this report are based on numerous fundamental assumptions, including regulatory requirements, project contingencies, low-level radioactive waste disposal practices, high-level radioactive waste management options, and site restoration requirements. The decommissioning scenarios assume continued operation of the station's spent fuel pools for a minimum of five and one half years following the cessation of operations for continued cooling of the assemblies.
The cost projected to promptly decommission the station (DECON), manage the spent fuel, and restore the site, is estimated to be $1.846 billion. The majority of this cost (approximately 63.7%) is associated with the physical decontamination and dismantling of the nuclear plant so that the operating license can be terminated.
Another 29.8% is associated with the management, interim storage, and eventual transfer of the spent fuel. The remaining 6.5% is for the demolition of the designated structures and limited restoration of the site.
The cost projected for deferred decommissioning (SAFSTOR) is estimated to be $2.098 billion. The majority of this cost (approximately 68.5%) is associated with placing the plant in storage, ongoing caretaking of the plant during dormancy, and the eventual physical decontamination and dismantling of the nuclear plant so that the operating license can be terminated. Another 25.7% is associated with the management, interim storage, and eventual transfer of the spent fuel. The remaining 5.9% is for the demolition of the designated structures and limited restoration of the site.
The primary cost contributors, identified in Tables 6.1 and 6.2, are either labor-related or associated with the management and disposition of the radioactive waste.
Program management is the largest single contributor to the overall cost. The magnitude of the expense is a function of both the size of the organization required to manage the decommissioning, as well as the duration of the program. It is assumed, for purposes of this analysis, that CPPC will hire a Decommissioning Operations Contractor (DOC) to manage the decommissioning. CPPC will provide site security, radiological health and safety, quality assurance and overall site TLG Services, Inc. 000118
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 6, Page 2 of 5 administration during the decommissioning and demolition phases. Contract personnel will provide engineering services, e.g., for preparing the activity specifications, work procedures, activation, and structural analyses, under the direction of CPPC. The size and composition of the management organization varies with the decommissioning phase and associated site activities. However, once the operating licenses are terminated, the staff is substantially reduced for the conventional demolition and restoration of the site, and the long-term care of the spent fuel (for the DECON alternative). Finally, both the estimates for DECON and SAFSTOR include the costs of disposing of the retired steam generators, the reactor vessel closure head, and spare high and low pressure turbine rotors from Unit 1. The study assumes that the disposal of the components would occur after shutdown, however, the costs are identified separately because the disposal activities could be conducted at any time.
As described in this report, the spent fuel pools will remain operational for a minimum of five and one half years following the cessation of operations. The pools will be isolated and an independent spent fuel island created. This will allow decommissioning operations to proceed in and around the pool areas. Over the five and one half-year period, the spent fuel will be packaged into transportable canisters for relocation to the ISFSI.
The cost for waste disposal includes only those costs associated with the controlled disposition of the low-level radioactive waste generated from decontamination and dismantling activities, including plant equipment and components, structural material, filters, resins and dry-active waste. As described in Section 5, disposition of the low-level radioactive material requiring controlled disposal will be at Waste Control Specialists' Andrews County 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.
Removal costs reflect the labor-intensive nature of the decommissioning process, as well as the management controls required to ensure a safe and successful program.
Decontamination and packaging costs also have a large labor component that is based upon prevailing wages. Non-radiological demolition is a natural extension of the decommissioning process. With a work force mobilized to support decommissioning operations, non-radiological demolition can be an integrated activity and a logical expansion of the work being performed in the process of terminating the operating license. Prompt demolition reduces future liabilities and 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 TLG Services, Inc. 000119
Comanche Peak Nuclear Power Plant Document L11-1774-001, Rev. 0 Decommissioning Cost Analysis Section 6, Page 3 of 5 general expense, e.g., labor and fuel, of transporting material to the destinations identified in this report. For purposes of this analysis, material is primarily moved overland by truck.
Decontamination is used to reduce the plant's radiation fields and minimize worker exposure.
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.

Comanche Peak Nuclear Power Plant Document L11-1774-002, Rev. 0 Financial Escalation Analysis Page 5 of 37 INTRODUCTION This report presents the results of an escalation of the costs to decommission the Comanche Peak Nuclear Power Plant (Comanche Peak) to the projected year of expenditure. Financial schedules are provided for the base case, in which the nuclear units are expected to operate for 40 years. The baseline estimates (in 2019 dollars)[1] were adjusted for the required contingency ceiling and escalated using IHS forecast information. A twenty-five year moving average was used for future years beyond the current forecast horizon of the IHS database. A single value effective escalation rate (composite value) is also identified for each of the nuclear units. The results are summarized in Table 1. Order of Operations The process to escalate the decommissioning estimates was conducted in the following sequence:
- Source information was extracted from the latest decommissioning cost analyses (reproduced in Tables 2 and 3).
- The cost schedules were adjusted for the 10% ceiling value for contingency, as required by the Public Utility Commission of Texas' Substantive Rule §25.231(b)(1)(F)(i). The adjusted schedules are provided in Tables 4 and 5.
- The schedules of expenditures are presented in the following five categories: Labor, Equipment and Materials, Energy, Waste Disposal, and Other. The appropriate escalation index for each of the five escalation categories is identified, as summarized in Tables 6 and 7.
- The index values were applied against each of the unescalated schedules of expenditures to calculate a schedule of future value (Tables 7 and 8).
- An effective single value annual escalation rate was determined.
Escalation Factors The escalation indices selected for Labor, Equipment and Materials, Energy and Other cost categories are identified in Table 6 and were provided by IHS via their DataInsight-Web online service using first quarter 2020 projections. 1 "Decommissioning Cost Analysis for the Comanche Peak Nuclear Power Plant," Document No. L11-1774-001, TLG Services, Inc., May 2020 TLG Services, Inc. 000183
Comanche Peak Nuclear Power Plant Document L11-1774-002, Rev. 0 Financial Escalation Analysis Page 6 of 37 When the decommissioning schedule extended beyond the forecast database, the escalation was determined using a twenty-five year moving average logic. A disposal agreement with Waste Control Specialists for disposal services includes a provision for the future adjustment in rates. The IHS index equivalent to the index identified in this agreement was used to escalate low-level radioactive waste disposal costs to the year of expenditure. TLG Services, Inc. 000184

Public Utility Commission of Texas Memorandum To: John Harrison, Legal Division Fronn: Darryl Tietjen, Rate Regulation Division Date: September 21,2020 Re : Docket No . 50945-Application of Comanche Peak Power Company LLC for Review of Nuclear Decommissioning Cost Study and Funding Analysis Under 16 TAC § 25.3030)(2) Recommendation I recommend approval of the request by Comanche Peak Power Company LLC (CPPC) to maintain at current annual funding levels the amount of estimated decommissioning expense for Units 1 and 2 of the Comanche Peak Nuclear Power Plant (Comanche Peak). Additionally, I recommend approval of CPPC's request to adjust the allocations between the Unit 1 and Unit 2 decommissioning funds from 57.1% for Unit 1 and 42.9% for Unit 2 to 72.3% for Unit 1 and 27.7% percent for Unit 2. Background and General Information Both Units 1 and 2 of Comanche Peak have operating license terms of 40 years. Consistent with the expiration dates of the licenses, the expected dates for ceasing operations and beginning decommissioning expenditures are 2030 for Unit 1 and 2033 for Unit 2. On behalfofCPPC, the engineering firm TLG Services, Inc. (TLG) issued in May 2020 an updated analysis ofthe cost of decommissioning Units 1 and 2. TLG developed a cost estimate (expressed in year-2019 dollars) of $1.729 billion, an amount that refiects a contingency rate of 10 percent as required by 16 Texas Administrative Code (TAC) § 25.303(f)(2). Based on this cost estimate, and as further discussed below, an annual funding amount of $19.4 million over the remaining operating life of CPPC is necessary to fully fund the estimated future decommissioning costs. CPPC states in its application that the five-year average ofdecommissioning fund collections from 2015-2019 was $19.9 million annually. CPPC further states (on page 2 of its filing) that the assumptions in the decommissioning study, financial escalation analysis, and funding analysis "likely have inherent and considerable uncertainty based on the predictability of long-term costs and market conditions." As a result of these considerations, CPPC proposes no change in the current funding rate. Discussion The determination of an annual funding amount for future decommissioning expense requires various inputs and assumptions, including the rate at which the amount ofdecommissioning costs will escalate, the investment returns that the decommissioning trust fund will earn over time, the timing of the actual expenditures, and the overall time period over which the entire decommissioning process will occur. Based on the information in the current filing related to
Docket No. 50945-Staff Recommendation Page 2 of 2 Comanche Peak's updated decommissioning cost estimates, projected cost escalation, and anticipated investment returns, CPPC proposes no change in current collection levels, which, as noted above, have averaged $19.9 million per year over the last five years. CPPC does, however, propose an adjustment in the allocation between the Unit 1 and Unit 2 decommissioning funds from 57.1% for Unit 1 and 42.9% for Unit 2 to 72.3% for Unit 1 and 27.7% for Unit 2. 1 have reviewed the funding model and the information provided by CPPC in its filing and in response to informal discovery; this information includes the rates of return estimated by JP Morgan and Aon Hewitt,1 the tax and fee information provided by BNY Mellon, and the estimated decommissioning cost escalation rates as estimated by TLG. I believe that the types of investments and the expected rates of return assumed by the investment advisors over the investment horizon are reasonable and consistent with the provisions of 16 TAC § 25.303 (which establishes the investment guidelines for nuclear decommissioning trust funds), and I find that the composite cost escalation rate of approximately 2.65%, as estimated by TLG, is generally consistent with the escalation rates approved by the Commission in other recent proceedings involving decommissioning-expense funding.2 Incorporating the inputs described above into CPPC's decommissioning-expense funding model results in an annual funding amount of approximately $19.4 million. For purposes of collecting an appropriate amount of annual decommissioning-expense funding for Comanche Peak, and as a conservative approach to ensuring adequate funding levels given the degree of inherent uncertainty in long-term financial and economic projections, I believe that CPPC's request to maintain funding at the current levels is reasonable. Additionally, to achieve a proper balancing of funds for Units 1 and 2,1 believe it is reasonable to approve CPPC's request to adjust the allocation between the Unit 1 and Unit 2 decommissioning funds from 57.1% for Unit 1 and 42.9% for Unit 2 to 72.3% for Unit 1 and 27.7% for Unit 2. Accordingly, I recommend that the Commission approve CPPC's requests in this proceeding. 1 Aon Hewitt manages the trust investments, with Comanche Peak providing overall investment trust management oversight along with managers PIMCO, NISA Investment Advisors, Northern Trust, and BNY Mellon. 1 See, Application of NRG South Texas LP for Review ofthe Cost of Decommissioning Units 1 and 2 of the South Texas Project, Docket No . 48447 , Order ( Dec . 20 , 2018 ); Notice by the San Antonio City Public Service Board of Receipt of Updated Decommissioning Study and Filing Under 16 TAC § 25.303(D, DocketNo. 48556, Order (Mar. 1,2019).

Dear Commissioners:
On June 16,2020, in compliance with 16 Tex. Admin. Code (TAC) § 25.303(f)(2), Comanche Peak Power Company LLC (Comanche Peak), as Transferee Company (as defined in 16 TAC § 25.303(c)(2)), of the Comanche Peak Nuclear Power Plant (CPNPP) assets, filed a cover letter along with the Decommissioning Cost Analysis for the Comanche Peak Power Plant, the Financial Escalation Analysis for the Comanche Peak Nuclear Power Plant, and the Funding Analysis for Comanche Peak Nuclear Power Plant. Based on the results of the studies and analysis, Comanche Peak is not requesting a change to the established decommissioning funding levels for CPNPP. The filing package made in this docket was consistent with the filing Comanche Peak's predecessor transferee company made in 2010 in Docket No. 34277 (the last filing in which no change to the funding levels was requested). We believe the filing package contains sufficient information in the reports and analysis included for the Public Utility Commission of Texas (Commission) to find the filing compliant with 16 TAC § 25.303(f). However, to the extent the Chairman and the Commissioners feel further evidence is necessary to evaluate the current status of Comanche Peak's decommissioning fund, we will be happy to file and offer additional testimony, affidavit, or report from an appropriate company official specifically addressing any additional information the Commission would like. I will be available at the open meeting on November 5,2020, to answer any additional questions the Commission may have regarding this filing. Sincerely,

1 DIRECT TESTIMONY OF KRISTOPHER MOLDOVAN 2 I. POSITION AND QUALIFICATIONS 3 Q. PLEASE STATE YOUR NAME AND BUSINESS ADDRESS. 4 A. My name is Kristopher Moldovan. My business address is 6555 Sierra 5 Drive, Irving, Texas 75039. 6 Q. BY WHOM ARE YOU EMPLOYED AND IN WHAT CAPACITY? 7 B. I am Senior Vice President & Treasurer of Vistra Corp. (Vistra) and its 8 subsidiaries, including Comanche Peak Power Company LLC (Comanche 9 Peak or Company), the owner of Comanche Peak Nuclear Power Plant 10 (CPNPP) as well as its associated Nuclear Decommissioning Fund (NDF). 11 Q. PLEASE OUTLINE YOUR EDUCATIONAL QUALIFICATIONS AND 12 PROFESSIONAL EXPERIENCE. 13 C. I have an undergraduate degree in Engineering from the University of 14 Illinois at Urbana-Champaign and a law degree from the Duke University 15 School of Law.

PURPOSE OF TESTIMONY 11 Q. WHAT IS THE PURPOSE OF YOUR TESTIMONY? 12 A. The purpose of my testimony is to demonstrate that the Company is in 13 compliance with the Public Utility Commission of Texas (PUCT) 14 Substantive Rule applicable to nuclear decommissioning at 16 Tex. 15 Admin. Code (TAC) § 25.303. 16 Q. WHAT IS THE PURPOSE OF ANNUAL FUNDING OF THE 17 DECOMMISSIONING TRUST? 18 A. The purpose of funding an external trust is to ensure that adequate funds 19 are available to pay for the safe dismantlement of the facility at the end of 20 the useful life of both generating units and to comply with the U.S. Nuclear 21 Regulatory Commission (NRC) and PUCT requirements. This funding of 22 future costs allocates the expense of retiring the plants to the customers 23 who are receiving the benefits of its generation during its useful life. 24 Excess funding, if any, will be returned to ratepayers after the completion 25 of the plant's decommissioning or as otherwise allowed by NRC and 26 PUCT guidelines.

1 Ill. COMANCHE PEAK DECOMMISSIONING 2 A. Funding Requirements 3 Q. WHAT AMOUNT IS BEING REQUESTED FOR DECOMMISSIONING 4 EXPENSE IN THIS FILING? 5 A. Comanche Peak's current annual funding amounts approved in Docket 6 No. 44845 is $20,077,165. Comanche Peak proposes no change in the 7 current collection rate in this proceeding. 8 The Decommissioning Cost Analysis for Comanche Peak Nuclear 9 Power P/ant, prepared by TLG Services, Inc. (TLG) dated May 2020 10 ( Decommissioning Study ) and Financial Escalation Analysis for the 11 Comanche Peak Nuclear Power Plant ( Financial Escalation Analysis ), 12 prepared by TLG in May 2020, estimate the total cost to decommission 13 and completely dismantle CPNPP at $1,729 million in 2019 dollars 14 assuming a 10 percent contingency. As of December 31, 2019, the Net 15 After-Tax Value of the trusts for CPNPP Units 1 and 2 was 16 $1,316,460,673, with $623,952,136 for Unit 1 and $692,508,537 for Unit 2. 17 Based on the results of the Decommissioning Study and Financial 18 Escalation Analysis , Comanche Peak performed a Funding Analysis for 19 Comanche Peak Nuclear Power Plant ( Funding Analysis ) in June 2020 . 20 The Funding Analysis shows a -2.7 percent difference between the 21 required funding levels of $19.4 million and the five-year average CPNPP 22 decommissioning fund collections from 2015-2019 of $19.9 million 23 annually. Because of the small difference in the required funding levels 24 and five-year average collections and the inherent and considerable 25 uncertainty of the predictability of long-term costs and market conditions, 26 Comanche Peak proposed no change in the current collection rate. Moldovan - Direct Comanche Peak Power Company 2020 Nuclear Decommissioning Study 000005
1 Q. IS COMANCHE PEAK PROPOSING AN ADJUSTMENT IN THE 2 ALLOCATION OF THE DECOMMISSIONING FUNDS BETWEEN CPNPP 3 UNITS 1 AND 2? 4 A. Yes. Based on the results of the Funding Analysis, Comanche Peak 5 proposes an adjustment in the allocation between the Unit 1 and Unit 2 6 decommissioning funds from 57.1 percent for Unit 1 and 42.9 percent for 7 Unit 2 to 72.3 percent for Unit 1 and 27.7 percent for Unit 2. 8 B. Compliance with PUCT Rules 9 Q. ARE THERE SPECIFIC GUIDELINES FOR THE ESTABLISHMENT AND 10 FUNDING OF DECOMMISSIONING TRUSTS RELATED TO NUCLEAR 11 POWER PLANTS SUCH AS COMANCHE PEAK? 12 A. Yes. The NRC has established guidelines to ensure the adequacy of 13 funds for the safe dismantlement, decontamination, and disposal of the 14 generating units at the end of their useful lives. These guidelines apply to 15 both the amounts of fund contributions and the methods for funding for the 16 ultimate decommissioning of the units. The PUCT has also adopted rules 17 establishing certain requirements for nuclear decommissioning trusts. 18 Q. WHAT DOES THE PUCT'S SUBSTANTIVE RULE SPECIFY 19 CONCERNING THE MANAGEMENT OF THE DECOMMISSIONING 20 TRUST? 21 A. In general terms, 16 TAC § 25.303 specifies Comanche Peak's duties in 22 the selection of trustees and managers of decommissioning trust funds, 23 outlines what must be contained in the agreements between Comanche 24 Peak and these parties, and limits what investments may be included in 25 the portfolios of decommissioning trusts. Moldovan - Direct Comanche Peak Power Company 2020 Nuclear Decommissioning Study 000006
1 Q. HAS COMANCHE PEAK FOLLOWED THE GUIDELINES ADOPTED BY 2 THE PUCT IN THE SELECTION OF THE TRUSTEE AND MANAGER OF 3 THE COMANCHE PEAK NDF? 4 A. Yes. The Bank of New York Mellon has served as trustee for the NDF 5 since its inception in 1990. Dresdner RCM Global Investors, who has 6 served as the fixed income investment manager since the fund's inception 7 in 1990 was merged into Pacific Investment Management Company 8 (PIMCO) in 2002. In 1994, after rule changes allowed for equity 9 investments, Mellon's Nuclear Decommissioning Trust Stock Index Fund 10 (now DT DV Stock Index Fund) was first used to manage the equity 11 investments in the trust. This commingled equity fund was selected after 12 developing an investment strategy, evaluating alternatives, and 13 conducting a search. In 1998, after additional changes in the 14 Commission's investment rules and a new manager search, Northern 15 Trust Quantitative Advisors (now Northern Trust Investments, Inc.) was 16 hired to manage an additional separate account S&P 500 index fund. In 17 2017, after adoption of the most recent Investment Policy, the Northern 18 Trust Investments account was assigned to their Tax Advantaged Equity 19 team, with responsibility for both S&P 500 index and MSCI EAFE index 20 separate accounts, thus diversifying equity investments to include some 21 non-U.S. developed markets. In 2019, NISA Investment Advisors, LLC 22 was hired as a second fixed income separate account manager, to 23 complement and diversify from the fixed income management of PIMCO. 24 Performance for the investment managers is reviewed quarterly, and the 25 trustee is reviewed every few years, with formal reviews for the investment 26 managers and the trustee occurring as needed. Moldovan - Direct Comanche Peak Power Company 2020 Nuclear Decommissioning Study 000007
1 Q. HAS COMANCHE PEAK COMPLIED WITH THE PUCT'S GUIDELINES 2 CONCERNING THE MANAGER AND INVESTMENT AGREEMENTS? 3 A. Yes. Comanche Peak complied with those guidelines in the original 4 agreements, and subsequent amendments, which have all been filed with 5 the PUCT, most recently in Docket No. 45753. 6 Q. DOES THE MANAGEMENT AGREEMENT ADDRESS THE 7 INVESTMENT RESTRICTIONS SET FORTH IN 16 TAC § 25.303(e)(3)? 8 A. Yes, it does. The fund managers and trustee have been instructed to 9 follow the guidelines set forth in 16 TAC § 25.303, which limit the types of 10 securities that may be purchased and which also limit the equity securities 11 that can be held by the trust. 12 Q. DOES COMANCHE PEAK HAVE AN INVESTMENT POLICY THAT 13 ENSURES COMPLIANCE WITH THE INVESTMENT GUIDELINES IN 16 14 TAC § 25.303(e)? 15 A. Yes. Attached as Exhibit KM-1 is a copy of Comanche Peak's Nuclear 16 Decommissioning Trust Investment Policy, that became effective 17 September 1,2017. 18 Q. HOW DOES COMANCHE PEAK MAKE CONTRIBUTIONS TO THE 19 NDF? 20 A. Contributions are made monthly based on billings during the previous 21 month. 22 Q. PLEASE EXPLAIN THE PROCESS. 23 A. Assume that the April billing cycle begins on March 28th. Meters are read 24 that day, and the retail electric providers (REPs) are billed shortly 25 thereafter; assume it is March 2gth. Payments from REPs are not due until 26 35 days later, or May 3rd. This process then continues for each day of the 27 April billing cycle. On approximately May 15, Comanche Peak contributes 28 the full amount billed by Oncor Electric Delivery Company LLC (Oncor) in Moldovan - Direct Comanche Peak Power Company 2020 Nuclear Decommissioning Study 000008
1 April to the NDF. At that point, due to the 35-day payment period that 2 REPs have, only up to half of the April billing month bills are due and 3 monies have been collected from the REPs, at least half of the bills for the 4 April billing month are not yet due and the Rider NDC - Nuclear 5 Decommissioning Charges have not yet been received by Oncor or 6 Comanche Peak. Since the contribution is made at about the midpoint in 7 the collection period, effectively half of the contribution has been paid in 8 arrears, but the other half has been paid in advance, so the net for the 9 entire billing month is that the NDF effectively receives the contribution on 10 the same day that Oncor receives the revenues. Near the end of May, 11 Oncor remits to Comanche Peak the entire April billing month of the Rider 12 NDC billings (not collections) along with its settlement of substantially all 13 other intercompany accounts payable/receivable. 14 In sum, from a monthly net use of funds standpoint, the effect of 15 Comanche Peak's approach is that the NDF receives the contribution as 16 of the date the revenues are received by Oncor, without any delay. Thus, 17 Comanche Peak's approach provides a superior result for the NDF as 18 compared to waiting until Oncor has actually collected the revenues and 19 then making a weekly deposit of those receipts (or a monthly deposit with 20 imputed interest). This approach to deposits to the NDF is consistent with 21 the intent of 16 TAC § 25.303(g)(2)(C). 22 This approach was presented to the Commission in 2005 in Docket 23 No. 31252 (see Horton Testimony, pp. 8-9) and Order No. 2 approved the 24 filing, noting that "the docket was initiated as a compliance filing and is not 25 the proper forum for a contested case proceeding." In 2010, no separate 26 docket was initiated for the five year compliance filing for CPNPP, which 27 was placed by the Commission in Docket No. 34277. In 2015, the same 28 implied interest approach was presented to the Commission for CPNPP in Moldovan - Direct Comanche Peak Power Company 2020 Nuclear Decommissioning Study 000009
1 Docket No. 44845 (see Frenzel Testimony, pp. 10-11) and approved by 2 order of the Commission on November 6, 2015. 3 If the Commission orders a different approach to NDF deposits in 4 this proceeding, Comanche Peak will of course comply with the 5 Commission's order. 6 Q. WHAT FUNDING METHOD IS COMANCHE PEAK PROPOSING IN THIS 7 FILING, AND DOES IT COMPLY WITH THE PUCT'S GUIDELINES? 8 A. Comanche Peak is proposing to continue the external sinking fund method 9 used since the establishment of the NDF and that is required by the 10 PUCT's Substantive Rules. This method requires monthly irrevocable 11 deposits to an external trust to fund the future decommissioning of 12 Comanche Peak. At the present time, Comanche Peak is making monthly 13 contributions to the external, irrevocable trusts established in 1990. The 14 fund balances are included on page 1 of Funding Analysis. The current 15 funding amounts are based on a 1997 decommissioning study that was 16 updated and redetermined in 2000 for use in the TXU Electric Company 17 unbundled cost of service proceeding. The decommissioning study was 18 subsequently updated in 2005, 2010, and 2015. 19 A review of decommissioning expense must be performed every 20 five years as required by 16 TAC § 25.303(f)(2). Thus, Comanche Peak's 21 filing in this docket accomplishes Comanche Peak's requirement to further 22 update the decommissioning cost study and funding analysis. These 23 periodic reviews are required to assure the adequacy of funds for the new 24 technologies, decommissioning requirements, and other assumptions that 25 may change over time. Comanche Peak is also in compliance with 16 26 TAC § 25.303(c)(4), which requires the trust to be irrevocable and 27 external. Moldovan - Direct Comanche Peak Power Company 2020 Nuclear Decommissioning Study 000010
1 Q. WHAT EFFORTS DOES COMANCHE PEAK TAKE TO ACHIEVE 2 OPTIMUM TAX EFFICIENCY AS DEFINED IN 16 TAC 3 § 25.303(e)(3)(B)(iii)? 4 A. All decommissioning funds are deposited and invested in tax-qualified 5 nuclear decommissioning trusts, as called for under 16 TAC 6 § 25.303(e)(3)(B)(iii). In addition, Comanche Peak works with investment 7 managers to achieve tax efficiency within the management of the NDF 8 assets, as follows: (1) all managers are made aware of the taxable nature 9 of qualified decommissioning trusts and invest accordingly, and they are 10 evaluated on both a pre-tax and after tax basis; (2) rebalancing and other 11 transaction activity is done thoughtfully so as to reduce realized taxable 12 gains where possible, within the guidance provided by the Investment 13 Policy; and (3) investment manager Northern Trust Investments, through 14 their Tax Advantaged Equity team, makes trades explicitly for tax 15 efficiency purposes (e.g., capturing tax losses to offset gains elsewhere in 16 the portfolio) and assists in overall tax gain/loss positioning across the 17 NDF. 18 C. Assumed Escalation Rate 19 Q. WHEN WILL DECOMMISSIONING FOR CPNPP BEGIN, AND HOW 20 LONG WILL IT LAST? 21 A. Comanche Peak's operating license for CPNPP Units 1&2is for 40 22 years. Commercial operation began in 1990 and 1993 for units 1 & 2, 23 respectively. Therefore, for CPNPP Unit 1, the 2020 decommissioning 24 cost study projects that commercial operations will cease and 25 decommissioning expenditures will begin in 2030. For CPNPP Unit 2, the 26 study projects that commercial operations Will cease and 27 decommissioning expenditures will begin in 2033. Moldovan - Direct Comanche Peak Power Company 2020 Nuclear Decommissioning Study 000011
1 Q. HOW WERE THE COSTS USED TO DETERMINE THE FUNDING 2 LEVELS DEVELOPED? 3 A. As previously mentioned, the current funding amounts are based on a 4 1997 decommissioning study that was updated and re-determined in 2000 5 for use in the TXU Electric Company unbundled cost of service 6 proceeding. The decommissioning study was subsequently updated in 7 2005, 2010, and 2015. This most recent update to the decommissioning 8 costs was developed by TLG, the same industry expert that performed the 9 previous studies. 10 D. Trust Balance and Administration Cost 11 Q. WHAT IS THE CURRENT BALANCE IN THE NUCLEAR 12 DECOMMISSIONING TRUST? 13 A. The balance in the trust at December 31, 2019 is shown on page 3 of the 14 Funding Analysis. Since the income and capital gains realized by the trust 15 are taxed at 20 percent, it is necessary to adjust the balance for the 16 current tax liability on the unrealized gains. The current tax liability is 17 calculated by multiplying the tax rate of 20 percent times the difference 18 between the market value and the tax cost of the assets in each trust. The 19 net after-tax value of the trust, which is the market value less the tax 20 liability, is $623,952,136 for Unit 1 and $692,508,537 for Unit 2. While the 21 Trust has certain tax advantages, the income and capital gains obtained 22 by the Trust are only tax-deferred, not tax exempt. Failure to reduce the 23 balances to reflect the taxes owed on the income and capital gains 24 realized by the Trust will result in the Trust having inadequate funds to 25 meet the cost of decommissioning Comanche Peak. 26 Q. HOW WERE THE PROJECTED FEES AND ADMINISTRATION 27 EXPENSES DETERMINED? 28 A. The actual total annual fees and administration expenses incurred by the 29 trust are shown on page 4 of the Funding Analysis. This was used as the Moldovan - Direct Comanche Peak Power Company 2020 Nuclear Decommissioning Study 000012
1 basis to forecast fees and administration expenses. Several factors 2 influence these expenses and must be considered in forecasting future 3 expenses. First, there is a timing issue, as most of the expenses are paid 4 in arrears on a quarterly basis. Another significant factor is the allocation 5 between active managers and passive managers. The cost for active 6 managers is generally higher than for passive managers. At present, our 7 equity segment is passively managed and our fixed income segment is 8 actively managed. This allocation is expected to remain the same until the 9 equity allocation is reduced in later years, at which time the additional 10 allocations to cash should keep the fees relatively stable. Normal 11 expenses were developed from an analysis of full-year expenses from the 12 ten-year period 2010 to 2019. The average of the actual expenses over 13 this ten-year period was 0.1745 percent of NDF assets, which was used 14 for the pre-tax expense. 15 E. Assumed Net Investment Return 16 Q. WHAT NET INVESTMENT RETURNS (GROSS RETURN LESS 17 EXPENSES, FEES AND TAXES) WERE USED IN YOUR ANALYSIS? 18 A. Net investment returns after expenses, fees, and taxes, which vary based 19 upon asset allocation are detailed on pages 13-15 of the Funding Analysis 20 based on the time periods corresponding to stipulated portfolio 21 composition limits in 16 TAC § 25.303(e)(3)(B)(vi). 22 Q. PLEASE SUMMARIZE HOW THE NET INVESTMENT RETURNS WERE 23 DETERMINED. 24 A. The net investment return for each year was derived in three stages. First, 25 the long-term expected pre-tax gross investment return was determined 26 for equity, fixed income, and cash. Next, the expected rate for fees, 27 administration expenses and taxes was determined. Finally, asset 28 allocation was established for different time periods during the NDF's life. 29 The net investment return for the portfolio for each time period was Moldovan - Direct Comanche Peak Power Company 2020 Nuclear Decommissioning Study 000013
1 determined by subtracting the expected rate for fees, administration 2 expenses, and taxes from the combined equity, fixed income, and cash 3 returns and weighting each asset class's return. 4 Q. HOW WERE THE FORECASTED INVESTMENT RETURNS FOR EACH 5 ASSET CLASS DEVELOPED? 6 A. Forecasted investment returns for each asset class were sourced from JP 7 Morgan and from Aon Investments as shown on page 5 of the Funding 8 Analysis. Comanche Peak averaged the forecasted returns from these 9 sources to derive the forecasted returns for each asset class. Pages 13-15 10 of the Funding Analysis show the calculation of the projected returns. 11 Q. HOW DID YOU DETERMINE THE PORTFOLIO INVESTMENT MIX? 12 A. The portfolio investment mix between equity, fixed income, and cash was 13 developed by considering the liability of the trust, diversification, 14 preservation of assets, and the applicable provisions of the 16 TAC 15 § 25.303(e). Equity returns are significantly higher than the fixed income 16 and cash returns, so based on the future liabilities, the equity exposure 17 should be at the maximum permitted exposure, especially early in the life 18 of the trust when there is sufficient time to recover from any market 19 downturns. Pursuant to the restrictions of 16 TAC § 25.303(e), Comanche 20 Peak currently targets 60 percent of the NDF assets to be allocated to 21 equity securities. In the early years, there will be very little cash, and any 22 expenses can be covered with residual cash exposure while new 23 contributions and dividends are being invested or through shorter term 24 fixed income investments. Once decommissioning starts, Comanche Peak 25 will allocate funds to cash based upon the requirements of 16 TAC 26 § 25.303 and projected decommissioning expenditures as shown on 27 pages 13-14 of the Funding Analysis. The remainder of the NDF 28 (approximately 40 percent prior to the start of decommissioning) is 29 invested in fixed income securities. Moldovan - Direct Comanche Peak Power Company 2020 Nuclear Decommissioning Study 000014
1 Q. WHEN DO YOU EXPECT TO REDUCE THE EQUITY EXPOSURE, AND 2 WHY? 3 A. While a large allocation to equity investments is appropriate for long-term 4 liabilities, as payment of decommissioning expenses draws closer, the 5 volatility of equities requires a reduction in the equity exposure to preserve 6 capital. 16 TAC § 25.303(e)(3)(B)(vi) limits the equity exposure to 30 7 percent in years in which decommissioning expenditures occur. For Unit 1, 8 this trigger point is reached in 2030, as shown on page 7 of the Funding 9 Analysis. Beginning in 2027, Comanche Peak assumed an orderly three-10 year transition from 60 percent equity to 30 percent equity, adjusting the 11 equity allocation by an average 10 percent each year to reach the required 12 level by 2030. As shown on page 8 of the Funding Analysis, the second 13 equity balance trigger point is reached in 2092, when the Weighted 14 Average Life of the NDF reaches 2.5 years and no equity investments are 15 allowed under 16 TAC § 25.303. Again, Comanche Peak assumed an 16 orderly three-year transition from 30 percent equity to 0 percent equity 17 beginning in 2089, adjusting the equity allocation by an average 10 18 percent each year to reach the required level by 2092. 19 Q. HOW DID YOU DETERMINE THE ALLOCATION TO CASH WITHIN THE 20 FIXED INCOME ALLOCATION? 21 A. During the collection period no cash is required as most cash needs can 22 be covered with contributions and income. As decommissioning 23 expenditures begin, the duration of the fixed income portfolio is shortened 24 by adding a cash allocation. Pages 13-15 of the Funding Analysis shows 25 the expenditures from the trust each year compared to the trust balance, 26 and a calculation of the average during different time periods. To maintain 27 sufficient liquid assets to meet the expected cash flow requirements, the 28 cash component within the fixed income allocation for the period was 29 assumed to be the percent required each year. Cash includes any fixed Moldovan - Direct Comanche Peak Power Company 2020 Nuclear Decommissioning Study 000015
1 income security with a maturity of less than one year, and these levels are 2 consistent with Comanche Peak's investment strategy. 3 Q. PLEASE SUMMARIZE COMANCHE PEAK'S PORTFOLIO INVESTMENT 4 MIX FOR EACH OF THE THREE TIME PERIODS YOU HAVE 5 DISCUSSED? 6 A. The investment mix used in calculating the net investment returns detailed 7 on pages 13-15 of the Funding Analysis are as follows: 8
- 60 percent Equities, 40 percent Fixed Income in 2019 through 9 2027, then ramping down to 30 percent equity by 2030; 10
- 30 percent Equities, Cash in the percent required to meet 11 expenditures for the year, and the remainder in Fixed Income in 12 2030 through 2088, then ramping down to 0 percent equity by 13 2091;and 14
- The percent required to meet expenditures in Cash and the 15 remainder in Fixed Income for 2091 and thereafter.
16 Q. WHAT OTHER COSTS WERE INCLUDED IN THE FORECAST OF 17 INVESTMENT RETURNS? 18 A. Federal income taxes must also be included. The current federal income 19 tax rate of 20 percent is assumed to remain constant during the life of the 20 trust. Additionally, it is assumed there will be no state income tax. 21 Q. WHAT ACTIONS WILL COMANCHE PEAK TAKE IN THE FUTURE TO 22 ASSURE THE ADEQUACY OF THE DECOMMISSIONING FUNDING 23 AMOUNTS? 24 A. The funding amounts being requested in this case have been carefully 25 and thoughtfully derived. Nevertheless, of necessity, assumptions have 26 been made regarding future economic conditions, including inflation rates, 27 investment performance, investment alternatives, tax rates, and timing of 28 expenditures. Furthermore, future changes in technology and regulatory Moldovan - Direct Comanche Peak Power Company 2020 Nuclear Decommissioning Study 000016
1 requirements can impact the decommissioning cost itself. Periodic reviews 2 of all assumptions and cost estimates, in light of experienced and 3 expected conditions, will therefore be conducted at least every five years 4 throughout Comanche Peak's operating life, as required by 16 TAC 5 § 25.303(f)(2). When appropriate, Comanche Peak will request 6 adjustments to the funding amount to recognize needed changes. 7 Q. ARE ANY OF THE DECOMMISSIONING FUNDS DEPOSITED IN "NON-8 QUALIFIED" ACCOUNTS? 9 A. No. 10 F. Decommissioning Funding Plan 11 Q. PLEASE DESCRIBE THE FUNDING PLAN USED TO DERIVE THE 12 EXPENSE LEVELS REQUESTED. 13 A. The funding plan shown on pages 20-24 of the Funding Analysis uses the 14 assumptions described previously, and projects the trust investments and 15 expenditures from January 1, 2015, through December 31, 2096, on an 16 annual basis. The annual calculations for each unit are shown on pages 17 20-24. Column (B) shows the funding levels (contributions to the trust) 18 based on the current collection rate through 2033. Column (C) indicates 19 the expected earnings of the fund based on the net investment return 20 discussed earlier in my testimony. The investment return percentage is 21 applied to the ending balance of the prior period plus one half the current 22 period contributions, less the current period decommissioning outlays. 23 Column (E) is the resulting balance of the fund at the end of each time 24 period, taking into consideration fund contributions, earnings, and 25 decommissioning expenditures. At the end of the assumed 26 decommissioning period, the trust balance, or the sum of all contributions 27 and earnings less expenditures nets to zero, for each unit.

1 Q. PLEASE SUMMARIZE YOUR DECOMMISSIONING FUNDING 2 TESTIMONY. 3 A. Utilizing the assumptions detailed earlier, the latest site-specific update for 4 Comanche Peak decommissioning, and the PUCT's 10 percent 5 contingency limitation, a decommissioning expense of $19,352,282 per 6 year, shown on page 24 of the Funding Analysis, is appropriate and 7 reasonable. Thus, no change to Oncor's Rider NDC - Nuclear 8 Decommissioning Charge is necessary. 9 IV. CONCLUSION 10 Q. ARE THE COMANCHE PEAK NUCLEAR DECOMMISSIONING TRUST 11 FUNDS INVESTED PRUDENTLY AND IN COMPLIANCE WITH 16 TAC 12 § 25.303(e)? 13 A. Yes. The agreements, practices, and policy I described in this testimony 14 ensure Comanche Peak's compliance with 16 TAC § 25.303(e). 15 Q. PLEASE SUMMARIZE YOUR TESTIMONY. 16 A. Comanche Peak's proposed costs of nuclear decommissioning are 17 reasonable. These costs have been developed in compliance with the 18 PUCT's rules and utilizing sound investment principles. The annual 19 funding requirements have been calculated using reasonable projections 20 as to investment returns, inflation levels, and administrative costs and 21 fees. Collections from the current Rider NDC are consistent with the 22 annual funding requirements that have been calculated by Comanche 23 Peak, such that no increase to the collection rate is necessary at this time. 24 Q. DOES THIS CONCLUDE YOUR DIRECT TESTIMONY? 25 A. Yes, it does. Moldovan - Direct Comanche Peak Power Company 2020 Nuclear Decommissioning Study 000018

Docket No. 50945 Exhibit KM-1 Page 4 Asset Mix Asset Class Minimum Normal Maximum Equity 0% 60% 60%
-Domestic 0% 40% 60% -Non US 0% 20% 25%
Fixed Income 35% 40% 100% Cash 0% 0% 5% The guidelines and objectives in this IPS outline an asset allocation that the Committee has determined is appropriate for managing the Fund assets. Furthermore, in developing this asset allocation, the Committee and its Advisor considered the following:
- Broad economic factors;
- Historical and prospective information regarding the capital market performance;
- Applicable investment strategies; and

Rebalancing may be implemented through any combination of the following actions: a) purchase/sale of securities, b) allocation of new contributions. If market fluctuations raise the equity allocation above the maximum, new contributions are to be allocated to Fixed Income until the Asset Mix is back to the Normal allocation. Reallocation of current investments may also be considered for moving toward Normal allocations, ifjudged prudent. V.

' Order Remaining Proceeding to Docket Management (Nov. 5,2020).
Testimony of Darryl Tietjen in Support of the Supplemented Application December 11,2020
Docket No. 50945 Page 4 of 6 1 IV. DISCUSSION 2 Q. Please describe the key information Mr. Moldovan provides in his testimony and how 3 you believe it addresses the evidentiary deficiencies identified by the Commission. 4 A. The Commission ' s Order Remanding Proceeding to Docket Management ( filed November 5 5,2020) states that "...the application and subsequent filings did not include evidence 6 required by 16 Texas Administrative Code § 25.303(f)(4)(A), (B), and (D)...." 7 With regard to the requirements of the referenced subparagraph (A) of subsection 8 (f)(4) of the decommissioning rule,2 it is my opinion that the filing of Mr. Moldovan's 9 testimony and the information contained therein demonstrate the necessary compliance. I 10 believe that Mr. Moldovan's testimony provides an appropriately detailed discussion ofthe 11 decommissioning cost study, the related funding analysis, and the requested funding 12 amount. 13 With regard to the referenced subparagraph (B) of subsection (f)(4) of the 14 decommissioning rule,3 Mr. Moldovan's testimony includes an attachment (Exhibit KM-15 1 ) containing CPPC ' s Investment Policy that, in my opinion , demonstrates the prudence of 16 the decommissioning trust funds' investment policies and compliance with the rule's 17 investment guidelines . In addition to a number ofvarious otherissues , CPPC ' s Investment 18 Policy addresses key points such as the trust funds' asset allocations, tax considerations, 19 performance objectives, and criteria for the selection and retention ofthe funds' investment 20 managers. 21 With regard to the referenced subparagraph (D) of subsection (f)(4) of the 22 decommissioning rule,4 Mr. Moldovan states on page 11, lines 4 through 6 ofhis testimony 2 The provisions of 16 TAC § 25.303(0(4)(A) state that "The cost study and funding analysis shall be accompanied by a report or testimony supporting the analyses and the requested annual funding amount." 3 The provisions of 16 TAC § 25.303(f)(4)(B) state that "The Nuclear Decommissioning Trust Funds administrator shall demonstrate that the decommissioning funds are being invested prudently and in compliance with the investment guidelines in subsection (e) of this section." 4 The provisions of 16 TAC § 25.303(f)(4)(D) state that "The Transferee Company (or the funds administrator and the Transferee Company, if different) shall demonstrate efforts to achieve optimum tax efficiency as defined in subsection (e)(3)(B)(iti) ofthis section, including, as applicable, maintenance oftax-exempt status Testimony of Darryl Tietjen in Support of the Supplemented Application December 11,2020
Docket No 50945 Page 5 of 6 1 that, "All decommissioning funds are deposited and invested in tax-qualified nuclear 2 decommissioning trusts, as called for under 16 TAC § 25.303(e)(3)(B)(iii)." As a point of 3 additional reference, I would note that his statement is consistent with the information 4 contained in CPPC's most recent annual nuclear decommissioning report that CPPC filed 5 on May 13 , 2020 in Project No . 34277 , Annual Report on the Status of Nuclear 6 Decommissioning Funding . Based on this information , I believe that CPPC has 7 demonstrated compliance with the requirements of 16 TAC § 25.303(f)(4)(D). 8 9 Q. Do you believe that CPPC's funding process flows through to ratepayers appropriate 10 economic benefits? 11 A. Yes. Mr. Moldovan discusses on pages 8 through 10 of his testimony the process by which 12 CPPC makes monthly contributions to the decommissioning trust fund. As he explains, 13 CPPC's monthly funding process-which differs in funding frequency from the weekly 14 funding period described in 16 TAC § 25.303(g)(2)(C)-reflects the fact that a certain 15 portion of the funding contribution is essentially a pre-funding of amounts that have been 16 billed to ratepayers but not yet actually paid, and the result is a time-value-of-money effect 17 that replicates the imputation of interest. Mr. Moldovan indicates in his testimony (at the 18 bottom of page 9) that CPPC and its predecessors have used (and the Commission has 19 approved) this funding approach for at least the last 15 years. 20 21 Q. Do you generally agree with Mr. Moldovan's statement on page 9, lines 14 through 22 16 of his testimony that, "from a monthly net use of funds standpoint, the effect of 23 Comanche Peak's approach is that the NDF receives the contribution as of the date 24 the revenues are received by Oncor, without any delay"? 25 A. Yes. I would note, however, that I also agree with his statements on page 10, lines 3 26 through 5 of his testimony, where he states, "Ifthe Commission orders a different approach 27 to NDF [Nuclear Decommissioning Fund] deposits in this proceeding, Comanche Peak or efforts to achieve 'qualified' status in accordance with Internal Revenue Code §468A (or any successor thereto) with respect to its taxable nuclear decommissioning trust funds." Testimony of Darryl Tietlen in Support o f the Supplemented Application December ll,2020
Docket No. 50945 Page 6 of 6 1 will of course comply with the Commission's order," As I indicated above, I believe that 2 the process by which CPPC makes contributions to the trust fund appropriately takes into 3 account the time value of money; nevertheless, I understand that the Commission may 4 choose to direct CPPC to alter the funding process so as to more explicitly reflect the effect 5 ofimputed interest as provided for in 16 TAC § 25.303(g)(2)(C). 6 7 Q. Does this conclude your testimony? 8 A. Yes. Testimony of Darryl Tietjen in Support of the Supplemented Application December 11,2020

LKK Commissioner Shelly Botkin FROM: Chairman DeAnn T. Walker &19/ DATE: January 28,2021 RE: January 29, 2021 Open Meeting - Item No. 4 Docket No . 50945 - Applicalion of Comanche Peak Power Company LLC for Review of Nuclear Decommissioning Cost Study and Funding Analysis Under 16 TAC § 25.303*(2) I recommend that the Commission make the following changes to the revised proposed order in this proceeding. A new heading and findings of fact should be added after finding of fact 30 and a new conclusion of law should be added after conclusion of law 10 to address the need for a good cause exception. Subsequent findings of fact and conclusions of law should be renumbered accordingly. Good Cause Exception
- 31. It is Comanche Peak's practice is to make monthly deposits to the nuclear decommissioning trust funds. Comanche Peak does not use an imputed interest calculation in setting the decommissioning charge.
- 32. Every month at mid-month Comanche Peak deposits the amount of nuclear decommissioning charges that will be due from billings for the entire previous month to the nuclear decommissioning trust fund. At that mid-month point, about half of the previous month's bills are due from retail electric providers, so half of the contribution to the fund is paid in advance. The effect of Comanche Peak's process is that the nuclear decommissioning fund receives Comanche Peak's contribution the same day the collecting utility receives the revenues. without any delay or need to impute interest.
Conclusion of Law
- 11. Under 16 TAC § 25.303(h),good cause exists to waive the requirement in 16 TAC 4 25.303(g)(2)(C) that if deposits to the nuclear decommissioning trust funds are less frequent that weekly, an implied interest calculation shall be used in setting the decommissioning charge.
Finally, I propose delegating to the Office of Policy and Docket Management staff the authority to modify the order to conform to the Citation and Style Guide for the Public Utility
Commission of Texas and to make other non - substantive changes to the order for such matters as capitalization, spelling, grammar, punctuation, style, correction of numbering, and readability. I look forward to discussing this matter with you at the open meeting. 2
