INTRODUCTION Pursuant to Section 184 of the Atomic Energy Act of 1954, as amended ("AEA"), and 10 C.F.R.
§ 50.80 and 10 C.F.R. § 72.50, NextEra Energy Duane Arnold, LLC ("NEDA"), Central Iowa Power Cooperative ("CIPCO"), and Corn Belt Power Cooperative ("Corn Belt") (collectively, the "Applicants"), hereby submit the enclosed application ("Application") requesting that the U.S.
Nuclear Regulatory Commission ("NRC") consent to the consolidation of all outstanding ownership interests in the Duane Arnold Energy Center and its generally licensed independent spent fuel storage installation (collectively, "DAEC") in NEDA, the current operator licensee and 70% owner of the DEAC. Specifically, Applicants seek to transfer (1) CIPCO's 20% ownership interest of the DAEC and (2) Corn Belt's 10% ownership interest of the DAEC to NEDA (the "Transfers").
Upon approval, NEDA would retain licensed operational authority under Renewed Facility License No. DPR-49 and would become the 100% owner of the DAEC. The Transfers do not otherwise alter the DAEC operations, the DAEC's management, or the technical qualifications of NEDA to continue serving as the operator licensee.
The proposed Transfers will be consistent with the requirements set forth in the AEA, NRC regulations, and the relevant NRC licenses and orders. The Applicants, therefore, respectfully request that the NRC consent to the transfer of control in accordance with Section 184 of the AEA as well as 10 C.F.R. § 50.80 and 10 C.F.R. § 72.50. A conforming license amendment is required to reflect the Transfer in order to remove references to CIPCO and Corn Belt. Attachment A includes a markup version of the license.
II.
STATEMENT OF PURPOSE OF THE TRANSFER AND NATURE OF THE TRANSACTION MAKING THE TRANSFER NECESSARY OR DESIRABLE The proposed Transfers consolidate the corporate ownership of the DAEC into the current majority owner and operator licensee, NEDA, and have no impact on plant operations. NEDA has announced plans to seek reauthorization of power operation at the DAEC, and while the proposed license transfer is not required for the plant to continue towards reauthorization of power operations, the Applicants have decided that the Transfers will best position the Applicants for that process. Specifically, CIPCO and Corn Belt, electric generation and transmission cooperatives in the State of Iowa, have concluded that their members would be best served by using resources that would otherwise be put towards the DAEC for other uses.
At the consummation of the Transfers, the DAEC will continue to be managed safely by NEDA consistent with the requirements of the AEA, the NRC licenses, applicable requirements, and plant procedures. There will be no physical changes to the DAEC or day-to-day operations as a result of the Transfers, and NEDA will remain technically qualified to manage the units.
In summary, the proposed Transfers will not be inimical to the common defense and security or result in any undue risk to public health and safety, and the Transfers will be consistent with the requirements of AEA and NRC regulations.
Duane Arnold Energy Center Docket No. 50-331 111.
SUPPORTING INFORMATION A.
Facility Background L-2025-191 Page 3 of 7 The DAEC is a single-unit 1,912 megawatts-thermal (MWt) General Electric boiling water reactor of the standard BWR-4 design located in Linn County, Iowa on the western bank of a north-south reach of the Cedar River, approximately two miles north-northeast of the Town of Palo.
The operating license for the DAEC was issued June 22, 1970, and the renewed operating license was issued December 16, 2010. NEDA was the licensed operator of the DAEC while in an operating status and is still the operator licensee while the DAEC is in decommissioning status.
NEDA has announced plans to obtain reauthorization of power operations at DAEC. However, this license transfer application is based on the DAEC's current licensing status and does not assume the authority to resume power operations will be granted.
B.
Description of the Transfer CIPCO and Corn Belt, two of the current licensed owners of the DAEC, have entered into agreements to transfer their 20% and 10% ownership interests, respectively, in the DAEC to NEDA. More specifically:
On October 24, 2025, NEDA and CIPCO entered into an Asset Purchase Agreement whereby CIPCO will transfer its 20% ownership interest of the DAEC to NEDA.
On October 24, 2025, NEDA and Corn Belt entered into an Asset Purchase Agreement whereby Corn Belt will transfer its 10% ownership interest of the DAEC to NEDA.
The proposed Transfers would result in NEDA becoming the sole licensed owner of the DAEC.
C.
General Corporate Information The Transaction will not alter the organizational structure or senior leadership of the existing majority owner and operator licensee NEDA. Attachment B provides the corporate organizational structure for NextEra Energy Duane Arnold, LLC.
D.
No Foreign Ownership, Control or Domination The Transfer will not result in any impermissible foreign ownership, control or domination of the DAEC. NEDA is currently licensed owner of the DAEC with operational authority and is a Delaware limited liability company. NEDA is ultimately controlled by NextEra Energy, Inc., a Florida corporation. Accordingly, the Transfer will not result in any impermissible foreign ownership, control or domination of the DAEC.
Duane Arnold Energy Center Docket No. 50-331 E.
Technical Qualifications L-2025-191 Page 4 of 7 CIPCO and Corn Belt are currently possession-only licensed minority owners of the DAEC. NEDA is and will continue to be the operator licensee that possesses the requisite technical qualifications. No changes in the management of or operational organization for the DAEC are expected to be made as part of the proposed Transaction. The proposed Transfer will not result in any changes to the senior management of NEDA, the staffing or qualifications of the DAEC site personnel, day-to-day operations, or the physical plant configuration. To the extent these matters are affected by proposed restart activities, they will be addressed with the NRC in that forum.
F.
Financial Qualifications for Operations The DAEC is currently in decommissioning status, so no financial qualifications for operations are required. However, because NEDA is planning restart of the DAEC, NEDA will address financial qualifications for operations during the restart process.
At the appropriate time, NEDA will reinstate the previous license condition requiring a parental support agreement sufficient to cover a six-month extended outage.
The new license condition and support agreement would be sufficient to cover NEDA's ownership of 100% of the DAEC following approval of the Transfers.
G.
Decommissioning Funding As described in further detail below, NEDA's current Nuclear Decommissioning Trust ("NOT") is sufficient to meet or exceed all NRC decommissioning funding requirements without the use of any funds from CIPCO or Corn Belt. Therefore, the Applicants request that the NRC approves the Transfers without requiring CIPCO or Corn Belt to transfer their NOT funds to NEDA and allow the release of those funds to CIPCO and Corn Belt, respectively. In other words, Applicants request that, upon approval of the Transfers, CIPCO and Corn Belt would be allowed to eliminate their NDTs and freely use those funds as appropriate for the benefit of their members.
Because NEDA has announced plans to pursue restart of the DAEC but has not yet applied for or received authority to restart, this application presents two scenarios: (1) No Restart and (2)
Restart. NEDA's NOT is sufficient to satisfy NRC funding requirements under either scenario.
- 1.
No Restart Scenario Under the No Restart Scenario, NEDA's NOT maintains sufficient funds to carry out the current decommissioning funding plan, including radiological decommissioning, spent fuel management, license termination, and Independent Spent Fuel Storage Installation ("ISFSI") decommissioning costs, without the need for transfer of NOT funds from CIPCO or Corn Belt.
The most recent decommissioning funding status report for the DAEC was submitted on March 17, 2025 (the "2025 DFS Report"). This report relied on an updated Decommissioning Cost Estimate showing the total estimated cost to decommission the DAEC to be $1,027,687,330 (for period of 2025-2080, escalated to 2024 dollars).
Attachment C to this application provides the same data as Attachment C-1 from the 2025 DFS Report with the following changes (1) updating the liability from 70% share to 100% share; (2) updating the cost estimate to 2025 dollars (for period of 2026-2080), $1,044,589,000; and (3) updating the NEDA NOT balance to September 30, 2025 balance minus projected expenses
Duane Arnold Energy Center Docket No. 50-331 L-2025-191 Page 5 of 7 through October 2025. 3 This chart shows 100% of the radiological decommissioning, spent fuel management, license termination, and ISFSI decommissioning costs can be funded from the NEDA NOT, without supplementation.4 Therefore, assuming restart of the plant does not proceed, the NEDA NOT is sufficient to fully fund the cost of completing the decommissioning the DAEC according to the current SAFSTOR process.
- 2.
Restart Scenario Under the Restart Scenario, NEDA's NOT maintains sufficient funds to meet the current NRC minimum by the end of the restarted plant's licensed life in 2034. Because of NEDA's current decommissioning status, the NRC minimum funding requirement in 10 C.F.R. § 50.75 does not apply.
See Entergy Nuclear Operations, Inc., Entergy Nuclear Palisades, LLC, Holtec International, and Holtec Decommissioning International, LLC, (Palisades Nuclear Plant and Big Rock Point Site), NRC Staff Position on the Applicability of the 10 C.F.R. § 50.75 Minimum Funding Requirement to the License Transfer Application (Nov. 18, 2022).
Nevertheless, because of the potential restart, this Application demonstrates that the NEDA NOT would meet the minimum funding requirement under the prepayment method. For the restart scenario, a spent fuel management plan under 10 C.F.R. § 50.54(bb) would be required in 2029, five years prior to the expiration of the current license, pending subsequent license renewal.
Attachment D to this application provides the basis for the calculated minimum. The 2025 total NRC minimum decommissioning amount for the DAEC calculated pursuant to 10 C.F.R. § 50.75 is $636,960,161. The NEDA NOT year-end 2025 balance is estimated at $616,618,4835.
Beginning January 2026, the fund is assumed to earn a 2% real rate of return each year through license expiry in 2034. After decommissioning, it continues to earn 2% annually for seven years, with a half-year return applied to the shutdown balance. Under these assumptions, the projected funding balance is $778,412,132. If a subsequent license renewal were pursued, crediting 20 additional years of growth would increase the NOT balance above $1 billion; however, such an extension is not necessary at this time. Following completion of radiological decommissioning, sufficient funds would remain to carry out ISFSI decommissioning under 10 CFR 72.30. An updated ISFSI decommissioning cost estimate is included in Attachment C.
- 3.
Conclusion Regarding Decommissioning Funding In sum, while CIPCO and Corn Belt currently maintain NDTs for their ownership shares in the DAEC, those NDTs are not necessary going forward. NEDA's NOT is sufficient to satisfy NRC requirements under both a "no restart" scenario and a restart scenario without contributions from Corn Belt or CIPCO.
3 Due to the announced restart, NEDA does not plan to withdraw funds from its NOT for expenses incurred after October 2025, for either SAFSTOR costs or spent fuel management. The "No Restart Scenario" nevertheless shows decommissioning costs incurred during the planned restart period, for conservatism.
4 NEDA acknowledges that its exemption for spent fuel management and license termination costs does not currently apply to the CIPCO and Corn Belt ownership shares. This is also shown for conservatism.
5 As of September 30, 2025, the NEDA NOT balance is $617,977,730. Deducting NEDA's 70% share of August-October 2025 costs, estimated at $1,359,247, results in a year-end balance of $616,618,483; this is the balance used in our funding calculations.
Duane Arnold Energy Center Docket No. 50-331 L-2025-191 Page 6 of 7 Because the DAEC is currently in decommissioning, NEDA expects that it will also be required to demonstrate adequate decommissioning under 10 C. F. R. § 50. 75 if and when it applies for restart.
In the unlikely event that funds are insufficient to meet that showing, NEDA will provide additional decommissioning assurance at that time.
H.
No Antitrust Considerations In accordance with the NRC's decision in Kansas Gas and Electric Company (Wolf Creek Generating Station, Unit 1), CLl-99-19, 49 NRC 441 (1999), antitrust reviews of license transfer applications after initial licensing are not required by the AEA.
I.
Nuclear Insurance The proposed Transfers will require a conforming amendment to the existing Price-Anderson indemnity agreement for the DAEC to remove the names of CIPCO and Corn Belt.
The Transfer will not change the required nuclear property damage insurance pursuant to 10 C.F.R. § 50.54(w) and nuclear energy liability insurance pursuant to Section 170 of the Act and 10 C.F.R. Part 140. NEDA will continue to maintain all required nuclear property damage insurance and nuclear energy liability insurance for the facility. In addition, annual reporting in compliance with 10 C.F.R. § 140.21 (e) provides reasonable assurance regarding the ongoing ability of the owners to pay any annual retrospective premium for their interests.
J.
Standard Contract for Disposal of Spent Nuclear Fuel NEDA will remain fully responsible for managing spent nuclear fuel at the DAEC, including the operation and management of the ISFSI. The Transfers will not affect the Standard Contract for Disposal of Spent Nuclear Fuel, which is already held by NEDA.
K.
Restricted Data This Transfer does not involve any Restricted Data or other classified defense information and will not result in any change in access to such Restricted Data. To the extent such information does become involved, NEDA will continue to appropriately safeguard such information in accordance with the AEA and applicable NRC regulations.
L.
Environmental Review The requested consent is exempt from environmental review, because it falls within the categorical exclusion contained in 10 C.F.R. § 51.22(c)(21) for which neither an Environmental Assessment nor an Environmental Impact Statement is required. Moreover, the proposed Transfer does not directly affect the actual operation and maintenance of the DAEC in any substantive way. The proposed Transfer does not involve an increase in the amounts, or a change in the types, of any radiological effluents that may be allowed to be released off-site and involves no increase in the amounts or change in the types of non-radiological effluents that may be released off-site. Further, there is no increase in the individual or cumulative occupational radiation exposure, and the proposed Transfer has no environmental impact. Therefore, pursuant to 10 C.F.R. § 51.22(b), no environmental impact statement or environmental assessment needs to be prepared in connection with the proposed Transfer.
Duane Arnold Energy Center Docket No. 50-331 M.
Independent Spent Fuel Storage Installation L-2025-191 Page 7 of 7 As noted above, the Transfers would also apply to the general license issued for the storage of spent fuel in the DAEC ISFSI pursuant to 10 C.F.R. § 72.210.
IV.
EFFECTIVE DATE AND REGULATORY APPROVALS Subject to satisfaction of all conditions to closing the Transaction, the parties are targeting closing as soon as reasonably practical. Accordingly, Applicants request that the NRC review this Application on a schedule that will permit issuance of an order consenting to the requested license transfers by March 31, 2026. Applicants are prepared to work closely with the NRC Staff to facilitate the prompt review of the Application.
Applicants request that the NRC's consent be immediately effective upon issuance and permit the Transfer to occur any time within one year after the approval is issued. NEDA will notify the NRC staff at least two (2) business days prior to the expected closing date. Applicants will keep the NRC informed of any significant changes in the status of other required approvals that could impact the anticipated closing date.
V.
CONCLUSION For the reasons stated above, the proposed transfers of the Licenses will not be inimical to the common defense and security or result in any undue risk to public health and safety, and the transfers will be implemented consistent with the requirements of the AEA, NRC regulations, the DAEC license, and the relevant NRC orders.
Applicants, therefore, respectfully request that, in accordance with Section 184 of the AEA, 10 C.F.R. § 50.80, and 10 C.F.R. § 72.50, the NRC consent to the Transfers.
