PERRY NUCLEAR POWER PLANT - REQUEST FOR INFORMATION FOR THE NRC AGE-RELATED DEGRADATION INSPECTION: INSPECTION REPORT 05000440/2026010
Dear Terry Brown:
The purpose of this letter is to request information to support our scheduled age-related degradation inspection beginning January 26, 2026, at Perry Nuclear Power Plant.
This inspection will be performed in accordance with NRC baseline inspection procedure 71111.21N.04 Age-Related Degradation.
An initial list of documents requested to support identification of structures, systems, and components (SSCs) that will be reviewed during the inspection is provided in enclosure 1.
For SSCs that the inspection team plans to review, an initial list of the documents the team plans to review during the conduct of the inspection is listed in enclosure 2. The team leader will contact you with identified SSCs. Also, personnel should be available at the site during the inspection who are knowledgeable regarding maintenance, surveillance, testing, inspection, and condition monitoring programs.
This letter contains voluntary information collections that are subject to the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.). The Office of Management and Budget (OMB) approved these information collections (approval number 3150-0011).
