February 18, 2021 Mrs. Maria L. Lacal Executive Vice President/
Chief Nuclear Officer Arizona Public Service Company P.O. Box 52034, MS 7602 Phoenix, AZ 85072-2034
SUBJECT:
PALO VERDE NUCLEAR GENERATING STATION UNITS 1, 2, AND 3 -
NOTIFICATION OF NUCLEAR REGULATORY COMMISSION DESIGN BASES ASSURANCE INSPECTION (PROGRAMS) (05000528/2021014, 05000529/2021014, AND 05000530/2021014) AND INITIAL REQUEST FOR INFORMATION
Dear Mrs. Lacal:
On May 10, 2021, the U.S. Nuclear Regulatory Commission (NRC) will begin an onsite inspection at the Palo Verde Nuclear Generating Station Units 1, 2, and 3. A three-person team will perform this inspection using NRC Inspection Procedure 71111, Attachment 21N.02, Design Bases Capability of Power-Operated Valves Under 10 CFR 50.55a Requirements.
This inspection will evaluate the reliability, functional capability, and design basis of risk-important power-operated valves as required by 10 CFR 50.55a and applicable 10 CFR Part 50, Appendix A and Appendix B, requirements, and as required by the Palo Verde Nuclear Generating Station Units 1, 2, and 3 Operating Licenses. Additionally, the team will perform an inspection of the documentation files to verify that the plant activities associated with safety-related motor-operated valves meet your commitments to Generic Letter (GL) 89-10, Safety-Related Motor-Operated Valve Testing and Surveillance, and GL 96-05, "Periodic Verification of Design-Basis Capability of Safety-Related Motor-Operated Valves." In conducting this inspection, the team will select power-operated valves used to prevent and mitigate the consequences of a design basis accident.
The inspection will include an information gathering site visit by the team leader and two weeks of onsite inspection by the team. The inspection will consist of three NRC inspectors. The current inspection schedule is as follows:
Onsite Information Gathering Visit: March 22-26, 2021 Preparation Weeks: May 3-7, 2021, and May 17-21, 2021 Onsite Weeks: May 10-14, 2021 and May 24-28, 2021
M. Lacal The purpose of the information gathering visit is to meet with members of your staff to become familiar with the power-operated valve activities at the Palo Verde Nuclear Generating Station.
The lead inspector will request a meeting with your personnel to discuss the site power-operated valve procedures. Additionally, the lead inspector will request a discussion with your staff to become familiar with the regulations and standards applicable to power-operated valves at the site. Additional information and documentation needed to support the inspection will be identified during the inspection, including interviews with engineering managers and engineers.
In order to minimize the inspection impact on the site and to ensure a productive inspection, we have enclosed a request for information needed for the inspection. This information should be made available to the lead inspector during the week of March 15-19, 2021. Since the inspection will be concentrated on safety-related and risk significant power-operated valves, a list of such power-operated valves should be available to review during and following the information gathering visit to assist in our selection of appropriate power-operated valves to review.
Additional requests by inspectors will be made during the onsite weeks for specific documents needed to complete the review of specific power-operated valves and associated activities. It is important that all these documents are up-to-date and complete in order to minimize the number of additional documents requested during the preparation and/or the onsite portions of the inspection. To facilitate the inspection, we request that a contact individual be assigned to each inspector to ensure information requests, questions, and concerns are addressed in a timely manner.
The lead inspector for this inspection is Mr. Ronald A. Kopriva. We understand that our licensing engineer contact for this inspection is Mr. Mohamed Diane. If there are any questions about the inspection or the requested materials, please contact the lead inspector by telephone at 817-200-1104 or by email at Ron.Kopriva@nrc.gov.
This letter contains mandatory information collections that are subject to the Paperwork Reduction Act of 1995 86& HWVHT The Office of Management and Budget (OMB) approved these information collections (approval number 31500011). Send comments regarding this information collection to the Information Services Branch, Office of the Chief
