Title | Licensee-Identified Violation |
Description | Unit 2 Technical Specification 3.4.3, Safety/Relief Valves, required that twelve of thirteen MSRVs lift at a setpoint within plus or minus three percent of a specified value. Contrary to this, during TS required surveillance testing following the Unit 2 Cycle 15 refueling outage, the licensee discovered that the lift setpoints of seven MSRVs exceeded the TS allowed pressure band. This TS violation was entered into the licensees CAP as PER 175990. The finding was determined to be of very low safety significance because the as-found lift setpoint conditions of the Unit 2 MSRVs were analyzed and determined to meet the design basis criteria for the most limiting over-pressurization events |
