SUBJECT:
VOGTLE ELECTRIC GENERATING PLANT UNITS 3 & 4 - NOTIFICATION OF INSPECTION AND REQUEST FOR INFORMATION FOR NRC PROBLEM IDENTIFICATION AND RESOLUTION INSPECTION
Dear Jamie Coleman:
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 Vogtle Electric Generating Plant Units 3 & 4 during the weeks of August 4-8, 2025, and August 18-22, 2025. The inspection team will be led by William Truss, the Vogtle Electric Generating Plant Units 1 & 2 resident inspector. This inspection will be conducted in accordance with the baseline inspection procedure, 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 May 15, 2025, William Truss confirmed with William Garrett, Licensing Manager, the details and arrangements for the two-week inspection. Based on recent experience and to improve efficiency, we plan to conduct the first week (August 4-8, 2025) remotely and plan to complete the inspection on-site (August 18-22, 2025).
The enclosure lists documents that will be needed prior to the inspection. Please have the referenced information available no later than July 21, 2025. Contact William Truss 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, William Truss 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.
May 16, 2025
J. Coleman 2
The NRC inspection team requests that your staff be prepared to support these efforts.
Additionally, the inspection team is open to any suggestions regarding communications and coordination such that the overall effort from both the NRC inspection team and Vogtle Electric Generating Plant Units 3 & 4 support staff may be the most efficient while also prioritizing public health and safety.
In accordance with Title 10 of the Code of Federal Regulations 2.390, Public Inspections, Exemptions, Requests for Withholding, of the NRC's "Rules of Practice," a copy of this letter and its enclosure will be available electronically for public inspection in the NRCs Public Document Room or from the Publicly Available Records (PARS) component of the NRC's Agencywide Documents Access and Management System (ADAMS). ADAMS is accessible from the NRC website at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).
Thank you for your cooperation in this matter. If you have any questions regarding the information requested or the inspection, please contact William Truss at (404) 997-5313.
