Finding

Title

HPCI System Exhaust Pressure Switches Exceeded Documented Qualified Life

Description

The inspectors identified a Green NCV of 10 CFR Part 50, Appendix B, Criterion III, Design Control, because Exelon did not establish measures to ensure that environmental qualification requirements for qualified components were correctly translated into procedures and instructions. Specifically, the end-of-life replacement requirements for the Unit 2 HPCI exhaust pressure switches were not translated into maintenance procedures and instructions. As such, Exelon did not replace the switches prior to the end of their documented qualified life.
