| Title | Licensee-Identified Violation |
| Description | A violation of Technical Specification 5.4.1.a was identified by the licensee for the failure to establish adequate work instructions to ensure proper installation of the gap setting between the actuator stem and valve stem of Unit 1 HPCI, (High Pressure Coolant Injection), turbine stop valve, 1-FCV-073-0018. On April 19, 2012, during the performance of a quarterly surveillance test the turbine stop valve, 1-FCV-073- 0018, failed to close upon repeated demands. A Phase 3 analysis determined the significance of the finding was very low safety significance (Green) The regional Senior Reactor Analyst performed a Phase 3 SDP analysis on the finding. The risk was dominated by the unavailability of the HPCI during the repair time after discovery of the Stop Valve issue. The finding was determined to be GREEN in the SDP, primarily due to the short period of time it was fully non-functional. The licensee initiated PER 539040 to enter the issue into their corrective action program. |
