II. Background

Accelerated Decommissioning Partners Crystal River Unit 3, LLC (ADP CR3, licensee) is currently the licensed operator responsible for decommissioning of Crystal River Unit 3 Nuclear Generating Plant (CR3). Prior to ADP CR3, Duke Energy Florida (DEF) held the licensed authority for CR3. The Facility Operating License No. DPR-72, provides, among other things, that the facility is subject to all rules, regulations, and orders of the NRC now or hereafter in effect. The facility is located in Citrus County, Florida.

By letter dated February 20, 2013, pursuant to paragraphs 50.82(a)(1)(i)-(ii) of title 10 of the Code of Federal Regulations (10 CFR), DEF formally notified the NRC that it had determined to permanently cease power operations at CR3 and that it had permanently removed fuel from the reactor vessel. In this letter, DEF explained that CR3 had been safely shutdown since September 26, 2009, and that all fuel had been permanently removed from the CR3 reactor vessel as of May 28, 2011, and had been placed in the CR3 spent fuel pool for temporary storage.

DEF described its proposed decommissioning activities and schedule in its Post-Shutdown Decommissioning Activities Report (PSDAR) submitted on December 2, 2013. At that time, DEF decided to place the facility in long-term storage ( i.e., the SAFSTOR decommissioning option). SAFSTOR is a decommissioning method in which a nuclear facility is placed and maintained in a condition ( printed page 22176) that allows the facility to be safely stored and subsequently decontaminated to levels that permit release for unrestricted use.

By letter dated June 14, 2019, as supplemented by letters dated January 17, 2020, and March 5, 2020, DEF and ADP CR3 requested that the NRC consent to the proposed direct transfer of licensed authority under CR3 Facility Operating License No. DPR-72 and the general license for the CR3 Independent Spent Fuel Storage Installation (ISFSI) from DEF to ADP CR3. ADP CR3 is a joint venture between NorthStar Group Services and Orano USA. By letter dated June 26, 2019, ADP CR3 submitted a revised PSDAR contingent upon NRC approval of the direct transfer of the licensed authority to ADP CR3. The revised PSDAR changed the decommissioning approach for CR3 from SAFSTOR to the immediate implementation of the DECON decommissioning option. DECON is a method of decommissioning in which structures, systems, and components that contain radioactive contamination are actively removed from the site and safely disposed of at a commercially operated low-level waste disposal facility or decontaminated to a level that permits the site to be released for unrestricted use as soon as possible after removal of the spent fuel from the spent fuel pool.

By Order dated April 1, 2020, the NRC provided its consent to the direct transfer of licensed authority. On October 1, 2020, DEF transferred the licensed authority to ADP CR3 pursuant to the terms of the transfer agreement between DEF and ADP CR3, as proposed in the June 14, 2019, letter. Per the agreement, DEF remained the NRC-licensed owner of the plant, property, and decommissioning trust fund while ADP CR3 became the NRC-licensed operator responsible for decommissioning and maintaining the ISFSI under a service agreement with ADP SF1. ADP SF1 became the owner of the spent nuclear fuel, high-level waste, and Greater-Than-Class C waste stored in the ISFSI.

On October 15, 2025, as supplemented December 11, 2025, and February 25, 2026, ADP CR3 submitted its LTP to the NRC. Paragraph 50.82(a)(9), “Termination of license,” specifies that an application for license termination must be accompanied or preceded by a LTP which is subject to NRC review and approval. The LTP addresses site characterization to ensure that the scope of final status surveys (FSS) of the site cover all areas where contamination existed, remains, or has the potential to exist or remain, identification of remaining dismantlement activities, plans for site remediation, a description of the FSS plans to confirm that CR3 will meet the release criteria in 10 CFR part 20, subpart E, “Radiological Criteria for License Termination,” dose-modeling scenarios that ensure compliance with the radiological criteria for license termination, an estimate of the remaining site-specific decommissioning costs and an updated assessment of the environmental effects of decommissioning CR3. Once approved, the LTP would become a supplement to the CR3 Defueled Safety Analysis Report.

According to 10 CFR 50.82(a)(9)(iii), after the licensee submits an LTP the NRC must hold a public meeting near the site. The purpose of the meeting is for the NRC staff to discuss the NRC's review of the LTP and to request public comments on the LTP. In addition, in accordance with 10 CFR 50.82(a)(9)(iii) and 20.1405, upon the receipt of an LTP from a licensee, NRC must publish a notice in the Federal Register and solicit comments from affected parties.

IV. Request for Comment and Public Meeting
