Finding

Title

Licensee-Identified Violation

Description

The licensee identified a violation of TS 3.4.3 which required that twelve of thirteen MSRVs lift at a setpoint within plus or minus 3 percent of a specified value. Contrary to this, during surveillance testing following the Unit 3 Cycle 13 refueling outage, the licensee discovered that eight MSRVs did not meet the TS allowed pressure band as described in the licensees PER 146189. This finding was determined to be of very low safety significance because the as-found lift setpoint conditions of the Unit 3 MSRVs were analyzed and demonstrated to meet the design basis criteria for an over-pressurization event
