SUBJECT:
PALO VERDE NUCLEAR GENERATING STATION - NOTIFICATION OF BIENNIAL PROBLEM IDENTIFICATION AND RESOLUTION INSPECTION AND REQUEST FOR INFORMATION (05000528/2023010; 05000529/2023010; 05000530/2023010)
Dear Mr. Heflin:
During the weeks of June 26 to 30, 2023, and July 10 to 14, 2023, the Nuclear Regulatory Commission (NRC) will conduct a Biennial Problem Identification and Resolution (PI&R) inspection at your facility. Four inspectors will perform this two-week inspection in accordance with NRC Inspection Procedure 71152, Problem Identification and Resolution. This inspection focuses on the corrective action program and implementation to evaluate the stations effectiveness in identifying, prioritizing, evaluating, and correcting problems, and to confirm that the station was complying with NRC regulations and licensee standards. The team also evaluates the stations processes for use of industry and NRC operating experience information and the effectiveness of the stations audits and self-assessments. Finally, the team reviews the stations program to establish and maintain a safety-conscious work environment.
The schedule for the inspection is as follows:
Offsite Preparation Week:
June 20 - 23, 2023
Onsite Inspection Weeks:
June 26 - 30 & July 10 - 14, 2023 To minimize the inspection impact on the site and to ensure a productive inspection for both parties, we have enclosed a request for information. It is important that all these documents are up to date and complete to minimize the number of additional documents requested during the preparation and/or the on-site portions of the inspection. Please provide this information electronically to the lead inspector.
