| Title | Licensee-Identified Violation |
| Description | Technical Specification 3.3.1.1 RPS Instrumentation Surveillance Requirement (SR) 3.3.1.1.17 requires the licensee to verify the RPS response time is within limits. Additionally, TS 3.3.4.1 End-of-Cycle Recirculation Pump Trip (EOC-RPT), SR 3.3.4.1.5 requires the licensee to verify the EOC-RPT system response time is within limits. Both SRs have a frequency of 24 months on a staggered basis. Contrary to the previously mentioned requirements, on May 20, 2011, the licensee discovered that they failed to perform a PMT on the Unit 2 Turbine Control Valve fast closure pressure switch, 2C71-K8A. Specifically, following the replacement of 2C71-K8A during L2R13, the RTT for RPS input and EOC-RPT, were not performed. As a result, the licensee was in violation of TS 3.3.1.1 and TS 3.3.4.1.5 until a downpower was performed to complete the RTT. This finding was assigned a very low safety significance because of channel redundancy and because both protective functions would have still been accomplished. The licensee entered this issue into their CAP as IR 1221750 and performed a root cause evaluation. Additional corrective actions include revising the Work Package Quality Checklist to prompt a TS review and developing a procedure for personnel to ensure appropriate PMTs are provided for outage WOs on TS-related components. |
