Request for Exemption from 10 CFR 50.82(a)(8)

Dresden Nuclear Power Station, Units 2 and 3 Renewed Facility Operating License Nos. DPR-19 and DPR-25 NRC Docket Nos. 50-237 and 50-249 Quad Cities Nuclear Power Station, Units 1 and 2 Renewed Facility Operating License Nos. DPR-29 and DPR-30 NRC Docket Nos. 50-254, 50-265, and 72-53 In accordance with 10 CFR 50.12, Constellation Energy Generation, LLC (CEG) is requesting the U.S. Nuclear Regulatory Commission (NRC) approval of an exemption from 10 CFR 50.82(a)(8)(i) and (ii) for Dresden Nuclear Power Station, Units 2 and 3 (Dresden) and Quad Cities Nuclear Power Station, Units 1 and 2 (Quad Cities) to establish and fund subaccounts within the respective nuclear decommissioning trusts (NDTs) that would not be part of the funds necessary to provide funding assurance per 10 CFR 50.75. MidAmerican Energy Company (MidAmerican), a twenty-five percent owner of Quad Cities with a separate nuclear decommissioning trust, joins this request to establish and fund subaccounts within its NDT that would not be part of the funds necessary to provide funding assurance per 10 CFR 50.75.

The requested exemptions would allow CEG and MidAmerican to periodically transfer earnings from funds dedicated for activities consistent with the definition of decommission in 10 CFR 50.2 (radiological decommissioning) into separately maintained subaccounts still within the NDT. Funds accumulated in the subaccounts could be used to pay for activities that are part of the larger decommissioning process and not exclusively dedicated for radiological decommissioning, as strictly defined by the NRC. Transfers are limited to earnings from funds dedicated to radiological decommissioning in excess of that allowed to be credited by the NRC (2 percent) per 10 CFR 50.75. These newly established sub-accounts would not receive funds transferred from existing accounts dedicated to radiological decommissioning.

Funds in non-50.75 subaccounts would not be dedicated to radiological decommissioning and could be used to pay for decommissioning costs as defined in 26 CFR 1.468A-1(b)(6) in the Treasury Department regulations for Section 468A of the Internal Revenue Code. This definition includes costs for radiological and non-radiological activities and certain spent fuel management activities whether the plant is operating or has permanently ceased operations. Thus, the funds could be used to pay for activities that are part of the larger decommissioning process that include transferring and safely storing spent fuel at the Independent Spent Fuel Storage Installations (ISFSIs) and decontamination, removal, and disposal of retired radioactive

U.S. Nuclear Regulatory Commission January 12, 2026 Page 2 components, which are under the regulatory authority of the NRC. Future Decommissioning Funding Assurance Reports required by 10 CFR 50.75(f)(1) will include the amount of funds transferred to the subaccounts since the last report.

The exemption request, if granted, would rely on earnings during operations. Therefore, the exemptions would only be needed during the operating lives of the reactors. The exemptions allowing movement of funds to the subaccounts would expire effective on an individual reactor basis at the time the certifications of permanent cessation of operations and permanent removal of fuel from the reactor vessel required under 10 CFR 50.82(a)(1)(i) and (ii) are docketed.

During decommissioning, funds already held in the subaccounts would be available, but not exclusively dedicated, to radiological decommissioning.

If approved, this exemption will facilitate activities that are part of the larger decommissioning process at Dresden and Quad Cities during operations, spent fuel management and site restoration, reduce overall decommissioning costs, and reduce an unnecessary regulatory burden on CEG and MidAmerican.

As described more fully in the attachments, the NDTs at Dresden and Quad Cities were originally established through ratepayer collections for the defined purpose of decommissioning Dresden and Quad Cities. Because these trusts currently contain funds substantially in excess of those required for radiological decommissioning, the transfer would have no adverse impact on those future decommissioning activities.

CEG and MidAmerican request that the NRC grant the requested exemption because:

(1)

The exemption, "will not present an undue risk to the public health and safety, and

[is] consistent with the common defense and security," in accordance with 10 CFR 50.12(a)(1), and (2)

Special circumstances are present that satisfy 10 CFR 50.12(a)(2).

CEG and MidAmerican demonstrate in the attachments that the request satisfies these provisions. Granting this exemption is consistent with the NRC decommissioning regulations (see 10 CFR 50.82(a)(6)) as it would not:

(1) eliminate the potential for unrestricted site release; (2) have a significant environmental impact not previously considered in environmental impact statements (EISs); or (3) decrease reasonable assurance that adequate funds will be available for decommissioning.

The exemption would support efforts to ultimately achieve unrestricted release of Dresden and Quad Cities, thus improving environmental conditions. In addition, prompt disposal when cost effective disposal alternatives are available eliminates future price uncertainty and potential risks associated with the future availability of disposal capacity.

Granting this request would facilitate the overall decommissioning process through radiological and non-radiological activities and certain spent fuel management activities. The funds could be used to pay for activities that are part of the larger decommissioning process that can include transferring and safely storing spent fuel at the ISFSIs and decontamination, removal, and

U.S. Nuclear Regulatory Commission January 12, 2026 Page 3 disposal of radioactive components. The adequacy of the available funds for Dresden and Quad Cities decommissioning is supported by the site-specific decommissioning cost estimate and the associated funding program.

The NRC has issued an interim staff guidance (ISG) that addresses using the exemption process to allow the use of the NDTs to dispose of Major Radioactive Components (MRCs).

This exemption request under 10 CFR 50.12 to fund the subaccounts using earnings from NDT funds dedicated for radiological decommissioning is similar in nature to the MRC exemption request. Hence, CEG and MidAmerican will follow the ISG to the best of its ability to support this exemption request.

CEG and MidAmerican are submitting this exemption request to provide timely resolution of this issue and support planning activities. Accordingly, CEG and MidAmerican requests approval of this request by May 31, 2026, to avoid the resource allocation and other expenses associated with activities that are part of the larger decommissioning process, which would be avoided if NDT subaccount funds can be used for activities not exclusively dedicated for radiological decommissioning.

This letter and attachment contain no new regulatory commitments.

Should you have any questions concerning this request, please contact Mr. Jeff Dunlap at (779) 231-5216 or Gretchen Kraemer, for questions directed to MidAmerican, at (515) 281-2990.

I.

Exemption Request In accordance with the provisions of 10 CFR 50.12, "Specific Exemptions," Constellation Energy Generation, LLC (CEG) and MidAmerican Energy Company (MidAmerican) requests that the U.S. Nuclear Regulatory Commission (NRC) grant an exemption from provisions of 10 CFR 50.82, "Termination of License." Specifically, CEG and MidAmerican request an exemption from the requirements in 10 CFR 50.82(a)(8)(i) and (ii) in order to establish and fund subaccounts within the nuclear decommissioning trust funds (NDTs) to pay for activities that are part of the larger decommissioning process and not exclusively dedicated to radiological decommissioning. In addition, this request follows the Interim Staff Guidance (ISG) issued by NRC staff that defines the information that would assist the NRC in evaluating a similar exemption request.1 The purpose of this exemption request is to establish and fund subaccounts with earnings in excess of that allowed to be credited by the NRC (2 percent) within the Dresden Nuclear Power Station, Units 2 and 3 (Dresden) and Quad Cities Nuclear Power Station Units 1 and 2 (Quad Cities) NDTs. The subaccounts will be used for activities that are part of the larger decommissioning process which will result in several benefits, as follows:

1) the inventory of radioactive waste and associated source term at each site will be reduced;

2) the costs associated with maintaining any retired major components and irradiated hardware on site and providing protection to workers from these can be avoided;

3) the overall cost to decommission the site will be reduced;

4) any uncertainty regarding future disposal cost and capacity is eliminated; and

5) assurance adequate funds will be available to decommission the reactor at the time the reactor ceases operation will be maintained.

Finally, the adequacy of the availability of funds for Dresden and Quad Cities decommissioning is supported by the site-specific decommissioning cost estimate (DCE) and the associated funding program.

Authorization of the use of NDT funds for activities that are part of the larger decommissioning process is in the public interest because it would immediately reduce on-site waste inventories, eliminate risks associated with future disposal, and reduce the eventual cost and complexity of decommissioning Dresden and Quad Cities. Consequently, authorization to fund subaccounts within the NDT would further the purpose of 10 CFR 50.82(a)(8), which is to provide reasonable assurance that the decommissioning trust funds will be adequate to accomplish their intended purpose.

Funds that will be deposited into the newly established subaccounts will not be taken from the existing funds dedicated to radiological decommissioning. Those funds will remain untouched and continue to meet NRC minimum funding and other decommissioning obligations. Rather, 1 "Interim Staff Guidance on the Use of the Decommissioning Trust Fund During Operations for Major Radioactive Component Disposal," August 5, 2024.

Request for Exemption from 10 CFR 50.82(a)(8)(i) and (ii) the subaccounts will be funded exclusively from investment earnings above and beyond the 2 percent assumed real rate of return allowed by the NRC at 10 CFR 50.75(e).

II.

Requirements The NRC regulations in 10 CFR 50.82(a)(8)(i) provide that decommissioning trust funds may be used by CEG or MidAmerican if:

(A) The withdrawals are for expenses for legitimate decommissioning activities consistent with the definition of decommissioning in 10 CFR 50.2; (B) The expenditure would not reduce the value of the NDT below an amount necessary to place and maintain the reactor in a safe storage condition if unforeseen conditions or expenses arise; (C) The expenditure would not inhibit the ability of CEG or MidAmerican to complete funding of any shortfalls in the NDT needed to ensure the availability of funds to ultimately release the site and terminate the license.

10 CFR 50.82(a)(8)(i)(A) refers to the definition of "decommissioning" in 10 CFR 50.2, which defines the term "decommission" rather than "decommissioning." By that definition, the term "decommission" means:

to remove a facility or site safely from service (emphasis added) and reduce residual radioactivity to a level that permits-(1) release of the property for unrestricted use and termination of the license; or (2) release of the property under restricted conditions and termination of the license.

The NRC has further conditioned the withdrawal of decommissioning trust funds by limiting the withdrawal rate from the trust. 10 CFR 50.82(a)(8)(ii) provides:

Initially, 3 percent of the generic amount specified in 10 CFR 50.75 may be used for decommissioning planning. For licensees that have submitted the certifications required under 10 CFR 50.82(a)(1) and commencing 90 days after the NRC has received the post-shutdown decommissioning activities report (PSDAR), an additional 20 percent may be used. A site-specific decommissioning cost estimate must be submitted to the NRC prior to the licensee using any funding in excess of these amounts.

In the absence of an exemption by the NRC, these provisions would restrict the ability of CEG or MidAmerican to use the NDT for activities that are part of the larger decommissioning process prior to permanent cessation of operations at Dresden and Quad Cities, even though activities that are part of the larger decommissioning process would reduce the level of radioactivity at Dresden and Quad Cities and would not adversely impact the ability to fund future decommissioning.

Request for Exemption from 10 CFR 50.82(a)(8)(i) and (ii)

A request for an exemption from these requirements must satisfy the requirements of 10 CFR 50.12. As demonstrated below, this exemption request satisfies the provisions of 10 CFR 50.12. In addition to providing the information requested by the NRC in the ISG, Applicants address the concerns expressed by the staff in its 2020 proposal to deny the EnergySolutions petition for rulemaking to allow for the use of decommissioning trust funds for the disposal of major radioactive components.2 Specifically, in recommending denial, the staff stated:

the staff envisions certain circumstances, which could be stated in an exemption request (a large projected excess in decommissioning trust funds compared to a site-specific cost estimate ) that may lead to the approval of the particular request, based on the totality of the facts.

While the staffs statement was specific to proposed exemptions for disposal of major radioactive component, the condition that there be a large projected excess in decommissioning trust funds compared to a site-specific cost estimate would seem to also apply to Applicants proposal for the funding of subaccounts. In the instance of this exemption request, Applicants can affirm that there will be a large projected excess in each of the NDTs after establishing and funding subaccounts with earnings in excess of that credited by the NRC (2 percent) within Dresden and Quad Cities respective NDTs.

III.

Background

In the context of NRCs decommissioning funding requirements, Applicants understand that it is NRCs position that depositing excess earnings from an NDT into a subaccount not dedicated to radiological decommissioning is a withdrawal not authorized under the rule. Therefore, NRC would not permit such withdrawals absent an exemption. Specifically, in 2023 PSEG provided notice to the NRC by letter that it intended to make changes to the PSEG Master Decommissioning Trust Agreement to create subaccounts into which excess decommissioning trust funds would be deposited.3 In its response to PSEGs notice, NRC stated that:

the earnings from funds originally dedicated for radiological decommissioning in a decommissioning trust fund, whether established under the prepayment method or otherwise, are restricted by the NRCs regulations at 10 CFR 50.82(a)(8)(i)(A) and 10 CFR 50.75(h)(1)(iv) to being withdrawn only for radiological decommissioning expenses, even when such earnings are claimed to be in excess of what is required for radiological decommissioning and are directed to subaccounts purporting to allow for other types of withdrawals.

NRC concluded by stating that PSEG would need to request and have approved an exemption, under 10 CFR 50.12, from the NRCs regulations at 10 CFR 50.82(a)(8)(i)(A) and 10 CFR 50.75(h)(1)(iv) in addition to amending the Trust Agreement.4 2 SECY-20-0095, "Denial of Petition for Rulemaking to Access the Decommissioning Trust Fund for the Disposal of Large Components," U.S. Nuclear Regulatory Commission, p. 2, October 19, 2020. The Commission approved the staffs recommendation in Staff Requirements Memorandum (SRM) SECY-20-0095 (Dec. 23, 2021).

Request for Exemption from 10 CFR 50.82(a)(8)(i) and (ii)

Accordingly, CEG and MidAmerican are submitting this exemption consistent with the NRCs statements.

In the Statements of Consideration for the 1996 amendments to its decommissioning regulations, the NRC received a comment requesting that The NRC should develop a policy for operating plants and should allow licensees to withdraw decommissioning trust funds to dispose of structures and equipment no longer being used for operating plants. In response, the NRC stated as follows:

The NRC has concluded that allowing decommissioning trust funds withdrawals for disposals by nuclear power plants that continue to operate is not warranted. These activities are more appropriately considered operating activities and should be financed that way5 This position is reflected in the NRCs regulations quoted above. Consequently, licensees have been precluded from using decommissioning trust funds for activities that are part of the larger decommissioning process.

The accumulating amounts of spent nuclear fuel and the ongoing lack of a federal repository for that fuel have resulted in the need for plant owners to store spent fuel in Independent Spent Fuel Storage Installations (ISFSIs) that was not anticipated when previous Treasury Department regulations were issued. Allowing funds to be used for activities that are part of the larger decommissioning process at any time during operations or decommissioning, such as transferring and safely storing spent fuel at the ISFSIs and decontamination, removal, and disposal of radioactive components, would more accurately reflect the current environment in which a permanent federal repository for spent fuel does not exist and CEG is required to provide long-term storage for spent fuel in the ISFSIs.

If the exemption is granted, funds deposited into the subaccounts from excess earnings could be allocated to pay for activities that are part of the larger decommissioning process and not restricted to radiological decommissioning. The subaccounts could be used to pay for decommissioning costs as defined by the Treasury Department regulations implementing Section 468A of the Internal Revenue Code. Specifically, 26 CFR 1.468A-1, Nuclear decommissioning costs; general rules, paragraph (b)(6) defines decommissioning costs to include costs for radiological and non-radiological activities and certain spent fuel management activities whether the plant is operating or has permanently ceased operations. The practice of commingling funds in the NDT is generally permitted under NRC guidance as long as the licensee is able to identify and account for the funds dedicated to radiological decommissioning separately from funds set aside for other purposes. Only earnings above 2 percent from NDT funds would be used as a source of funds for the subaccounts.

IV.

Basis The NRC definition of "decommission" states that the entire reactor facility must be removed from service before related activities fall within NRC-sanctioned decommissioning (10 CFR 50.2). Further, when the NRC promulgated the decommissioning rule in 1988, it noted in the Statements of Consideration to the final rule that "[d]ecommissioning activities are 5 Final Rule, Decommissioning of Nuclear Power Reactors, 61 FR 39278, 39293; July 29, 1996.

Request for Exemption from 10 CFR 50.82(a)(8)(i) and (ii) initiated when a licensee decides to terminate licensed activities."6 If this exemption were granted, CEG will perform activities that are part of the larger decommissioning process at any time during operations or decommissioning rather than waiting until the entire site is decommissioned. This is proposed to be accomplished using funds from the NDTs that were placed there for the purpose of removing such components. Absent this exemption, retired major components and irradiated hardware, would remain on site at each respective location until all units cease operation.

The regulatory history of the NRCs decommissioning regulations clearly contemplates the scenario proposed by CEG and MidAmerican in this exemption request. The NRCs regulations and guidance have emphasized compliance with the minimum funding requirements of 10 CFR 50.75(c) by taking credit for future earnings from investments of NDT assets. However, to the extent that a licensee does not need to take credit for future earnings in order to meet the minimum compliance requirements, there is a sound regulatory basis for diverting future NDT earnings into an Excess Earnings Subaccount within a qualified fund.

The most significant regulatory basis for doing this is the rulemaking history relating to NRCs 1988 rule. In the proposed rule, the NRC staff proposed including language that required accumulated earnings to be included in either the prepayment or external sinking fund method. For the prepayment method in the proposed 10 CFR 50.33(k)(2)(i), the proposed rule provided that the prepayment method involved a segregated account in an amount such that the principal plus accumulated earnings would be sufficient to pay decommissioning costs.7 For the external sinking fund method in the proposed 10 CFR 50.33(k)(2)(ii), the proposed rule provided establishment of a fund in which the total amount of the periodic deposits plus accumulated earnings would be sufficient to pay decommissioning costs at the time termination of operations is expected. The words plus accumulated earnings were deleted in the language ultimately adopted by the 1988 Final Rule in 10 CFR 50.75(e)(1)(i) &

50.75(e)(1)(ii).

In connection with the 1988 rulemaking, the NRC staff published its disposition of various comments to the proposed rule in NUREG-1221.8 Comment D 3.3.4 Prepayment was reported as follows:

Comment Summary One commenter stated that if a licensee uses the prepayment method the accumulated earnings in the decommissioning fund will reach a level larger than required to reflect the annual adjustment for inflation because the proposed rule does not recognize that the accumulated earnings will consist of an inflation adjustment component, a pure interest rate component, and a premium-associated-with-risk component. The commenter recommended that the proposed rule be modified to permit a licensee to withdraw the pure interest 6 Final Rule, Decommissioning Criteria for Nuclear Facilities, 53 FR 24,018, 24,019; June 27, 1988.

7 Proposed Rule, Decommissioning Criteria for Nuclear Facilities, 50 FR 5600, 5618 (Feb. 11, 1985) (emphasis added).

Request for Exemption from 10 CFR 50.82(a)(8)(i) and (ii) rate component and the premium-associated-with-risk component periodically from the prepayment fund. (133). (emphasis added)

Comment Analysis and Response The amendments indicate that in prepayment, at the time of decommissioning, the funds are in such amount that the principal plus accumulated earnings would be sufficient to pay decommissioning costs. There is nothing in these requirements which is intended to prevent a licensee from making sure that the fund does not reach a level higher than required. Measures which licensees may take to prevent that occurrence are outside the scope of this rule. The rule has been modified to clarify this. (emphasis added)

Thus, the NRC staff specifically acknowledged that there could be excess earnings from assets in an NDT that would not necessarily have to be dedicated to 10 CFR 50.75 purposes.

If a units existing NDT balance meets or exceeds the minimum funding requirement, there is no need to take credit for any earnings. Therefore, all earnings beyond the 2 percent assumed rate of return for the next year could be considered excess.

A. Dresden And Quad Cities Decommissioning Trust Funds

1. There Are Large Projected Surpluses In The Decommissioning Trust Funds The CEG NDTs at Dresden and Quad Cities were originally established through ratepayer collections, which included amounts for spent fuel management, however, this money was commingled in the overall NDTs and not separately accounted. Collections for CEG ended in 2006, but the historical collection amounts in conjunction with the license renewal to 80 years for Dresden and the license renewal to 60 years for Quad Cities has resulted in a robust funding level for Dresden and Quad Cities. MidAmerican is still actively recouping costs through rates and contributing the same to its separate trust. Because the Quad Cities license was renewed for 60 years and MidAmerican is actively recouping costs through rates and contributing the same to its separate trust, the MidAmerican trusts contain large surpluses for the Quad Cities units (See Section IV.A.3).

3. Status And Structure Of The Decommissioning Trust Fund CEGs funds for Dresden and Quad Cities were originally collected from ratepayers through 2006. The original collections were based on radiological decommissioning and spent fuel management costs, but the funds were not segregated or accounted for separately in the NDT.

Hence, they have historically been commingled and not reported separately to the NRC and are considered funds for radiological decommissioning.

MidAmerican is still actively recouping costs through rates and contributing the same to its separate Quad Cities NDTs. MidAmerican has not filed an electric rate case in its respective jurisdictions since 2014 and will not be filing in Iowa for several years. MidAmerican cannot adjust the collection of decommissioning funds outside of a rate case. Allowing MidAmerican to fund a subaccount pursuant to this exemption request will allow greater flexibility in the use of its resources for decommissioning activities and will allow MidAmerican to match the funding strategy of Constellation, which has operational control of the Quad Cities facility.

4. Decommissioning Funding Assurance History As noted previously, the amounts previously collected and the additional time for funds to grow has resulted in a robust funding level for Dresden Units 2 and 3 and Quad Cities Units 1 and 2.

Dresden and Quad Cities show in all cases that the respective fund value exceeds the minimum formula amount. Subaccount funding is limited to earnings from funds dedicated for radiological decommissioning in excess of that allowed to be credited by the NRC (2 percent), thus maintaining a 2 percent margin.

5. Funding Mechanisms To Cover Future Shortfalls In The Decommissioning Trust Fund (For A Merchant Plant Owner)

NRC regulations in 10 CFR 50.75(e) specify funding mechanisms that are acceptable for demonstrating financial assurance. Due to the current funding level of the Dresden and Quad Cities NDTs and continuing to credit fund growth anticipated under this exemption request, it is unlikely that any additional financial assurance would be required. In the unlikely event of a shortfall for Dresden or Quad Cities, CEG would use one of the authorized methods to make up any shortfall that may occur, including but not limited to a parent company guarantee. CEG meets the financial test in 10 CFR 30 Appendix A for providing a parent company guarantee (see Attachment 14) and could also provide additional assurances using a letter of credit or surety bond if required. Likewise, MidAmerican commits to use one of the authorized methods to restore the fund to its required levels should a shortfall occur, including but not limited to providing a parent company guarantee (see Attachment 15) or other assurance as required.

6. Current Financial Health Of Applicant Companies Pursuant to longstanding NRC financial qualification guidance under NUREG-1577, Revision 1, if an applicant "has an investment grade rating or equivalent from at least two of these sources

[Moodys Standard and Poors, and Value Line],the reviewer will find such applicant financially qualified". CEG maintains an investment grade credit rating with the S&P of BBB+ and Moody's of Baa1. It would require a three-notch downgrade from their current levels to BB+ and Ba1 to drop below an investment grade credit rating.

B. The Site-Specific Decommissioning Cost Estimate

1. The Site-Specific Decommissioning Cost Estimate Is Comprehensive The NRC requires in 10 CFR 50.75(f)(2) that each licensee prepare and submit a DCE at least five years prior to the projected end of operations. CEG already has in place a detailed, site-specific DCE. The most recent DCE is comprehensive; the total estimated costs include spent fuel management and site restoration in 2025 dollars based on the SAFSTOR scenario. License termination cost is in 2025 dollars that includes just plant and Independent Spent Fuel Storage Installation (ISFSI) license termination. Dresden also takes into consideration conservative additional spend of an earlier exemption for $20 million per unit for disposal of Steam Dryers.

$244 The site-specific estimate considers the lessons learned and industry experience gained from the decommissioning of several nuclear power plants in recent years. These plants include the completed projects at Maine Yankee, Connecticut Yankee, Yankee Rowe, Trojan, and Big Rock Point. Although some of those projects exceeded projected costs, the experience has led to improvements in the ability to prepare DCEs that address all costs. For example, the Zion Nuclear Power Station, where all physical decommissioning work has been completed, will be decommissioned for significantly less than the DCE that was prepared and submitted to the NRC. In addition, decommissioning projects that are underway at Vermont Yankee, Oyster Creek, and Pilgrim also are projected to be completed for less than estimated.

In particular, contemporary DCEs, including the one for Dresden and Quad Cities, account for the significant lessons learned in the segmentation and disposal of reactor pressure vessels.

The uncertainty with these projects has historically been very high, both in terms of the cost to complete the work and the estimate of the volume and class of low-level radioactive waste (LLW) generated.

Significant progress has been made in the ability to reduce the generation of Greater than Class C Waste (GTCC), which must be stored onsite in the ISFSI.

In addition, the DCEs include detailed staffing models based on recent experience and include activity-based contingency based on the complexity and uncertainty of each activity. The DCEs are consistent with industry standards as described in AIF/NESP036, Guidelines for Producing Commercial Nuclear Power Plant Decommissioning Cost Estimates," and NRC Regulatory Guide 1.202, "Standard Format and Content of Decommissioning Cost Estimates for Nuclear Power Reactors," February 2005.

Request for Exemption from 10 CFR 50.82(a)(8)(i) and (ii)

2. The Site-Specific Decommissioning Cost Estimate Is Reliable The DCE contains a thorough and comprehensive analysis of the anticipated costs of decommissioning. Previous decommissioning projects provide ample evidence that it is reasonable to rely on the DCE. Data for the three large PWRs that have been fully demolished (i.e., Connecticut Yankee, Maine Yankee, and Trojan) show that final decommissioning costs were less than projected in the DCE for two (Maine Yankee and Trojan) and 24 percent higher for Connecticut Yankee. These data indicate that the DCEs are reliable planning tools.

Furthermore, the difference in the case of Connecticut Yankee is now well understood.

Additional completed reactor decommissioning projects have continued to prove the reasonableness of DCEs.

One key reason that Connecticut Yankee stands out as an exception is that it entered the decommissioning process following an unplanned shutdown. The lack of planning was a key factor in the challenges that the project faced. Decommissioning planning is another area that has proven to show significant benefits in recent years. The Decommissioning Planning costs are also included in the most recent DCE. These lessons are useful even in the event of an unplanned shutdown and have been applied at the current generation of nuclear power plants undergoing decommissioning.

C. Withdrawal Of Funds Now From The NDT Will Not Jeopardize CEGs Ability To Fully Decommission Dresden And Quad Cities

1. There Will Be Sufficient Funds Available To Decommission Dresden And Quad Cities The NDT provides adequate assurance that funds will be available throughout the decommissioning period. As noted above, CEGs NDT balances for Dresden Units 2 and 3 reported for the end of calendar year 2024 were approximately $1,006 and $1,028 million, CEGs NDT balances for Quad Cities Units 1 and 2 (at 75 percent ownership) reported for the end of calendar year 2024 were approximately $634 and $720 million, and MidAmericans NDT balances for Quad Cities Units 1 and 2 (at 25 percent ownership) reported for the end of calendar year 2024 were approximately $435 and $435 million, respectively. These balances will continue to grow because only earnings above 2 percent on the NDT funds would be used as a source of funds for the subaccounts. The first 2 percent of earnings will remain in the NDTs.

2. The Withdrawal Will Not Reduce The Value Of The Decommissioning Trust Below An Amount Necessary To Place And Maintain The Reactor In A Safe Storage Condition If Unforeseen Conditions Or Expenses Arise (10 CFR 50.82(a)(8)(i)(B))

The use of NDT for the requested purpose will not reduce its value below an amount necessary to place and maintain the reactor in a safe storage condition. The NDT balances will continue to exceed the NRC minimum requirements for financial assurance for decommissioning and be considered fully funded for purposes of compliance with NRCs rules. Even with the requested action, Applicants not only have sufficient funds to place and maintain the reactor in a safe storage condition, but also expect to have more than sufficient funds to complete the NRC-required radiological decommissioning based on the site-specific DCE as shown in Attachments 2 through 13. Subaccount funding is limited to earnings from funds dedicated for radiological decommissioning in excess of that allowed to be credited by the NRC (2 percent).

m MidAmerican trust projections are conservative and do not include the amount MidAmerican is currently collecting and depositing in NDTs Request for Exemption from 10 CFR 50.82(a)(8)(i) and (ii)

3. The Withdrawal Will Not Inhibit The Ability Of Applicants To Complete Funding Of Any Shortfalls In The Decommissioning Trust Needed To Ensure The Availability Of Funds To Ultimately Release The Site And Terminate The License (10 CFR 50.82(a)(8)(i)(C))

The expenditure of NDT funds would not inhibit the ability of Applicants to complete funding of any shortfalls in the NDTs needed to ensure the availability of funds to ultimately release the site and terminate the license. Applicants propose funding subaccounts only with trust earnings in excess of 2 percent, the remaining funds in the trusts exceed the NRCs minimum funding requirements in accordance with 10 CFR 50.75.

V.

Justification Of Exemption And Special Circumstances 10 CFR 50.12, "Specific Exemptions," states that the NRC may grant exemptions from the requirements of the regulations in 10 CFR Part 50 if three conditions are met. The three conditions are: 1) the exemption is authorized by law, 2) the exemption will not present an undue risk to the public health and safety, and 3) the exemption is consistent with the common defense and security. In addition, section 50.12 provides that the NRC will not consider granting an exemption unless special circumstances are present.

A. The Requested Exemption Is Authorized By Law This exemption is authorized by law in accordance with 10 CFR 50.12(a)(1). No law exists that precludes the activities covered by this exemption request. The provisions of 10 CFR 50.82 as well as the definition of "decommission" at 10 CFR 50.2 were adopted at the discretion of the NRC consistent with its statutory authority. No statute required the NRC to adopt the specific regulations from which CEG and MidAmerican now seek an exemption. Rather, it is entirely within the NRCs discretion to determine that alternative means are adequate to provide reasonable assurance of adequate protection of safety.

B. The Requested Exemption Does Not Present An Undue Risk To The Public Health And Safety This exemption will not present an undue risk to the public health and safety. To the contrary, granting this exemption will result in increasing the protection to the public health and safety as a significant source term will be removed from the site and properly disposed of decades in advance of the time of these activities that are part of the larger decommissioning process if Applicants waited until the reactors cease operation. This will reduce the potential for exposures from this source.

C. The Requested Exemption Will Not Endanger The Common Defense And Security This exemption is consistent with the common defense and security because it removes a source term from the site sooner than would otherwise be the case without the exemption.

Request for Exemption from 10 CFR 50.82(a)(8)(i) and (ii)

D. Special Circumstances NRC regulations require that special circumstances be present in order to grant an exemption.

This exemption is justified based on three of the six special circumstances cited in the regulations. The following special circumstances from 10 CFR 50.12(a)(2) are present that warrant the granting of this exemption request:

1. The Regulation In The Particular Circumstances Conflicts With Other Rules Or Requirements Of The Commission (10 CFR 50.12(a)(2)(i))

In this particular circumstance, application of the regulations in 10 CFR 50.82(a) is in conflict with the philosophy underlying the approach the Commission has taken for expeditiously removing contamination. It is inconsistent with the timeliness requirements set up for materials licensees as it may provide an unnecessary economic barrier for the removal of source terms from reactor sites. Material licensees of the NRC are subject to the 1994 Decommissioning Timeliness Rule, 10 CFR 30.36, 40.42, 70.38, and 72.54, which requires licensees to decontaminate and decommission certain unused portions of operating nuclear materials facilities.

Allowing contaminated land, buildings, or equipment to remain on site was seen as a possible public and environmental liability and the Commission looked for ways to achieve early decommissioning of unused portions of materials facilities, absent any other operational or safety concerns that would increase the risk to the site. For valid and sound reasons, reactor licensees are not subject to this rule and, in fact, are allowed the SAFSTOR option under 10 CFR 50.82. Nevertheless, in this case, absent the requested exemption, the requirement creates an economic barrier for the Licensee, who seeks to make a prudent decision to remove a source term from the site.

In addition, granting an exemption to the regulations in 10 CFR 50.82(a) would be consistent with the philosophy underlying the approach the Commission took for the license termination rule.9 In 1997, for instance, NRC originally added 10 CFR 20.1406(a) which requires that Applicants for licenses, other than renewals, after August 20, 1997, shall describe in the application how facility design and procedures for operation will minimize, to the extent practicable, contamination of the facility and the environment, facilitate eventual decommissioning, and minimize to the extent practicable, the generation of radioactive waste.

More recently, in 2011, NRC further amended the license termination regulations to explicitly include an obligation to licensees during operations.10 Section 10 CFR 20.1406(c) requires that:

Licensees shall, to the extent practical, conduct operations to minimize the introduction of residual radioactivity into the site, including the subsurface, in accordance with the existing radiation protection requirements in subpart B and radiological criteria for license termination in subpart E of this part.

The NRC added this provision related to operations because, in its view, [t]he ALARA requirements in existing regulations do not explicitly address subsurface contamination and do not provide adequate assurance that additional legacy sites will be prevented. Before this final 9 Final Rule, Radiological Criteria for License Termination, 62 Fed. Reg. 39058 (July 21, 1997).

10 Final Rule, Decommissioning Planning, 76 Fed. Reg. 35512 (June 17, 2011).

Request for Exemption from 10 CFR 50.82(a)(8)(i) and (ii) rule, the NRC regulations did not explicitly specify licensees' obligations to survey subsurface contamination, nor did the regulations explicitly specify the requirement of licensees to conduct operations to minimize residual radioactivity at the site, including the subsurface. Therefore, the overarching intent of 10 CFR 20.1406 is to minimize the occurrence and severity of site contamination by proactively taking measures that will control contamination and facilitate eventual decommissioning. Consistent with this philosophy, these activities that are part of the larger decommissioning process would comply with the Commissions intent under 10 CFR 20.1406.

In contrast, the storage of any retired major components and irradiated hardware at Dresden and Quad Cities until permanent cessation of operations will increase the complexity of decommissioning and volume of waste to be disposed at the end of plant life. Moreover, this complexity will be exacerbated by the inventory of retired major components and irradiated hardware, stored onsite at other plants. Thus, permitting these activities that are part of the larger decommissioning process will reduce the inventory of waste material and eliminate this future decommissioning activity, consistent with the philosophy underlying 10 CFR 20.1406.

Nuclear reactor licensees, though not required to do so, should be permitted to utilize NDTs that are intended to cover the removal expense in advance of cessation of operations when such components no longer have a useful purpose. Early removal also could take advantage of the current favorable disposal pricing. However, without an exemption such items could remain on site for additional decades, particularly given current trends towards license renewal.

2. Application Of The Regulation In The Particular Circumstances Would Not Serve The Underlying Purpose Of The Rule Or Is Not Necessary To Achieve The Underlying Purpose Of The Rule (10 CFR 50.12(a)(2)(ii))

The underlying purpose of the rule is to provide adequate funds for ultimate decommissioning of the site. The application of the regulation restricts the expenditure of NDTs in this circumstance, which is unnecessary to achieve the underlying purpose of the rule. The purpose of the restrictions on fund withdrawal is to protect the health and safety of the public by assuring that there will be adequate funds available to complete NRC-required decommissioning activities following termination of the operating license. The above analysis of the site-specific DCE and the NDT demonstrates that funding will be adequate to complete decommissioning even if funds are withdrawn for activities that are part of the larger decommissioning process during operations. It is noteworthy that a licensee can exceed the three (3) and 20 percent limitations of 10 CFR 50.82(a)(8)(ii) if a site-specific DCE is submitted to the NRC. Once this cost estimate is provided to the NRC, the licensee, according to the 1996 Statements of Consideration, may withdraw funds without obtaining additional approvals from the NRC.11 Since the cash flow analysis from CEGs site-specific DCE is being submitted with this exemption request, NRC has the information that is needed to assess the requirements of 10 CFR 50.82(a)(8)(ii) before CEG exceeds the limitations.

As noted above, it is prudent from both the safety and economic sense to use funds from the NDT for activities that are part of the larger decommissioning process. Permitting this will reduce the inventory of waste material and eliminate this from the decommissioning activities at 11 61 FR 39278, 39285; July 29, 1996.

Request for Exemption from 10 CFR 50.82(a)(8)(i) and (ii) the end of plant life. The underlying purpose is also to protect the environment; delaying removal would be counterproductive for this underlying purpose.

Furthermore, it is clear from the regulatory history of the NRCs decommissioning funding rules that the proposed exemption would be consistent with the original intent of the rule. As explained above, when NRC originally issued the decommissioning funding requirements in 1988, it made clear that There is nothing in these requirements which is intended to prevent a licensee from making sure that the fund does not reach a level higher than required.12

3. The Exemption Would Result In Benefit To The Public Health And Safety That Compensates For Any Decrease In Safety That May Result From The Grant Of The Exemption (10 CFR 50.12(a)(2)(iv))

The exemption would result in benefit to the public health and safety because these activities that are part of the larger decommissioning process support efforts to ultimately achieve unrestricted release of Dresden and Quad Cities, thus improving environmental conditions.

Furthermore, there is no associated decrease in safety. Allowing the exemption will result in a net benefit to the public health and safety. Disposing of waste prior to the permanent cessation of operations is consistent with NRC policy to minimize the costs and complexity of decommissioning, which can only improve safety at the site.

VI.

Conclusion Granting this exemption will be consistent with the NRC decommissioning regulations as it: (1) would not eliminate the potential for unrestricted site release; (2) would not have a significant environmental impact not previously considered in Environmental Impact Statements, and (3) would not decrease reasonable assurance that adequate funds will be available for decommissioning. Conversely, the exemption would support efforts to achieve unrestricted release, improve environmental conditions as a result, and increase the effectiveness of the decommissioning fund for unrestricted release of the site.

In sum, it will facilitate the larger decommissioning process from the sites so that: (1) the inventory of radioactive waste and the associated source term at Dresden and Quad Cities will be reduced; (2) the costs associated with maintaining any retired major components and irradiated hardware on site and providing protection to workers can be avoided; (3) the overall cost to decommission the site will be reduced; (4) any uncertainty regarding future disposal cost and capacity is eliminated; and (5) adequate funds will be available to decommission Dresden and Quad Cities at the time the reactor ceases operation. Finally, the adequacy of the availability of funds for Dresden and Quad Cities decommissioning is supported by a site-specific Decommissioning Cost Estimate and the associated funding program.
