Description
Unit 3 Technical Specification 3.4.3, Safe … Unit 3 Technical Specification 3.4.3, Safety/Relief Valves, required that twelve of thirteen main steam safety relief valves (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 3 Cycle 9 refueling outage, the licensee discovered that the lift setpoints of two MSRVs exceeded the plus or minus three percent TS allowed pressure band. This TS violation was entered into the licensees CAP as PER 558488. The finding was determined to be of very low safety significance because the as-found lift setpoint conditions of the Unit 3 MSRVs were evaluated and determined to meet the design basis criteria for the most limiting reactor pressure vessel over-pressurization events.ressure vessel over-pressurization events.  +
