2023-24620. Accelerated Decommissioning Partners Crystal River Unit 3, LLC; Crystal River Unit 3 Nuclear Generating Plant; License Termination Plan

AGENCY:

Nuclear Regulatory Commission.

ACTION:

Notice of receipt; public meeting, and request for comment.

SUMMARY:

On December 12, 2022, as supplemented on June 9, 2023, the U.S. Nuclear Regulatory Commission (NRC) received from Accelerated Decommissioning Partners Crystal River Unit 3, LLC (ADP CR3, licensee) a license amendment request to add a license condition to include the requirements of a License Termination Plan (LTP) for the Crystal River Unit 3 Nuclear Generating Plant (CR3). The LTP provides details about the known radiological information for the site, the planned demolition and decommissioning tasks to be completed, and the final radiological surveys and data that must be obtained for termination of the NRC's license for CR3. The NRC is requesting public comments on CR3's LTP and will hold a public meeting to discuss the LTP.

DATES:

Submit comments by March 7, 2024. Comments received after this date will be considered, if it is practical to do so, but the NRC is able to ensure consideration only for comments received on or before this date. The public meeting will be held on Thursday, December 7, 2023, from 5 p.m. until 8 p.m. eastern time (ET), at the Citrus County Chamber of Commerce, located at 915 N Suncoast Blvd., in Crystal River, Florida. The public meeting is also accessible through an online webinar. See Section IV, “Request for Comment and Public Meeting,” of this document for additional information.

II. Discussion

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 a pressurized water reactor 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. DEF then placed the fuel in the CR3 spent fuel pool for temporary storage. After removing the fuel in 2011, DEF stated that it had determined it would retire CR3.

DEF submitted its Post-Shutdown Decommissioning Activities Report (PSDAR) on December 2, 2013. The PSDAR described DEF's proposed decommissioning activities and schedule. At that time, DEF decided to place the facility in long-term storage ( i.e., the SAFSTOR decommissioning option) as described in the PSDAR. SAFSTOR is a method of decommissioning in which a nuclear facility is placed and maintained in a condition that allows the facility to be safely stored and subsequently decontaminated (deferred decontamination) to levels that permit release for unrestricted use. DEF planned to continue in SAFSTOR until 2067.

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 from DEF to ADP CR3. By letter dated June 26, 2019, ADP CR3 submitted a revised PSDAR contingent upon the transfer of the CR3 license authority to ADP CR3 pursuant to the terms of the Decommissioning Services Agreement between DEF and ADP CR3. ADP CR3 is a joint venture between NorthStar Group Services and Orano USA. The revised PSDAR changed the decommissioning approach for CR3 from SAFSTOR to the immediate decontamination and dismantlement of the facility ( i.e., 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, the licensed authority was transferred from DEF to ADP CR3 pursuant to the terms of the Decommissioning Services Agreement between DEF and ADP CR3. Per the agreement, DEF remains the NRC-licensed owner of the plant, property, and decommissioning trust fund but not the spent fuel. ADP CR3 became the NRC-licensed operator responsible for decommissioning and maintaining the Independent Spent Fuel Storage Installation (ISFSI) under a service agreement with ADP SF1, and ADP SF1 became the owner of the spent nuclear fuel, high-level waste, and Greater-Than-Class C waste stored in the ISFSI.

On December 12, 2022, ADP CR3 submitted its LTP to the NRC as supplemented by letter dated June 9, 2023. 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.
