SUMMARY
The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting an integrated inspection at Palisades Nuclear Plant, in accordance with the Reactor Oversight Process. The Reactor Oversight Process is the NRCs program for overseeing the safe operation of commercial nuclear power reactors. Refer to https://www.nrc.gov/reactors/operating/oversight.html for more information.
List of Findings and Violations
No findings or violations of more than minor significance were identified.
Additional Tracking Items
None.
PLANT STATUS
The plant began the inspection period at full power. On May 20, 2022, power operations ceased. All reactor fuel was removed from the reactor vessel and safely stored in the spent fuel pool by June 10, 2022. By letter dated June 13, 2022, Entergy Nuclear Operations, Inc.
submitted a Certification of Permanent Cessation of Power Operations to the NRC certifying that the plant had permanently ceased power operations and that all fuel had been permanently removed (ADAMS Accession No. ML22164A067). Effective June 13, 2022, the NRC notified Entergy Nuclear Operations, Inc. that oversight activities will no longer be conducted in accordance with the Operating Reactor Assessment Program and that oversight activities will be conducted in accordance with the Decommissioning Power Reactor Program (ADAMS Accession No. ML22164A432). On June 28, 2022, Entergy Nuclear Operations, Inc. informed the NRC of the successful purchase and sale transaction closing of the Palisades facilities to Holtec Decommissioning International, LLC (ADAMS Accession No. ML22179A075). On the same day, the NRC issued license amendments transferring the Palisades Nuclear Plant facility license from Entergy Nuclear Operations, Inc. to Holtec Palisades, LLC; and Holtec Decommissioning International, LLC (ADAMS Accession No. ML22173A179).
INSPECTION SCOPES
Inspections were conducted using the appropriate portions of the inspection procedures (IPs) in effect at the beginning of the inspection unless otherwise noted. Currently approved IPs with their attached revision histories are located on the public website at http://www.nrc.gov/reading-rm/doc-collections/insp-manual/inspection-procedure/index.html. Samples were declared complete when the IP requirements most appropriate to the inspection activity were met consistent with Inspection Manual Chapter (IMC) 2515, Light-Water Reactor Inspection Program - Operations Phase. The inspectors performed activities described in IMC 2515, Appendix D, Plant Status, observed risk significant activities, and completed on-site portions of IPs. The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel to assess licensee performance and compliance with Commission rules and regulations, license conditions, site procedures, and standards.
