SUBJECT:
OCONEE NUCLEAR STATION - NOTIFICATION OF INSPECTION AND REQUEST FOR INFORMATION FOR NRC PROBLEM IDENTIFICATION AND RESOLUTION INSPECTION
Dear Steven Snider:
The purpose of this letter is to notify you that the U.S. Nuclear Regulatory Commission (NRC)
Region II staff will conduct a problem identification and resolution (PI&R) inspection at your Oconee Nuclear Station during the weeks of April 14, and April 28, 2025. The inspection team will be led by Evan Robinson, Resident Inspector, from the NRCs Region II office. This inspection will be conducted in accordance with the baseline inspection procedure 71152, Problem Identification and Resolution, effective January 1, 2024.
The biennial PI&R inspection and assessment of the licensees corrective action program (CAP) complements and expands upon the resident baseline inspections of routine daily screening of all corrective action program issues, quarterly focused issue reviews, and semiannual trend PI&R reviews.
On February 5, 2025, Evan Robinson confirmed with Laura Boyce of your staff, the two-week onsite inspection.
The enclosure lists documents that will be needed prior to the inspection. Please have the referenced information available no later than March 17, 2025, unless otherwise stated. Contact Evan Robinson with any questions concerning the requested information. The inspectors will try to minimize your administrative burden by specifically identifying only those documents required for inspection preparation.
If additional documents are needed, they will be requested when identified. Prior to the onsite inspection, Evan Robinson will discuss with your staff the following inspection support administrative details: availability of knowledgeable plant engineering and licensing personnel to serve as points of contact during the inspection; method of tracking inspector requests during the inspection; access to licensee computers; working space; arrangements for site access; and other applicable information.
February 7, 2025
S. Snider 2
In accordance with Title 10 of the Code of Federal Regulations 2.390, Public Inspections, Exemptions, Requests for Withholding, of the NRCs Rules of Practice, a copy of this letter will be available electronically for public inspection in the NRCs Public Document Room or from the Publicly Available Records (PARS) component of the NRCs Agencywide Documents Access and Management System (ADAMS).
