| Description | A self-revealing non-cited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, for failure of the licensee to ensure emergency operating procedures were adequate to ensure important activities could be satisfactorily accomplished. Specifically, the procedural inadequacy contributed to one crew out of three deciding to prematurely secure RCPs because the verbiage in OP-902-006, Loss of Main Feedwater Recovery, Step 7 did not adequately translate its basis. In particular, Step 7 directs the Operators: If Main Feedwater is lost for greater than 30 minutes AND ONE Motor driven Emergency Feedwater Pump is the only Emergency Feedwater Pump available, then stop ALL RCPs, but the step should instead tie the 30 minute timer to loss of adequate feed rather than strictly the loss of Main Feedwater. The licensee has entered this issue into their corrective action program as CR-WF3-2011-01619. The failure of the licensee to ensure proper emergency operating procedure adequacy was a performance deficiency. The performance deficiency is more than minor, and therefore a finding, because it adversely impacted the procedure quality attribute of the Mitigating Systems cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Using the Inspection Manual Chapter 0609, Significance Determination Process, Phase 1 Worksheets, the inspectors determined that the finding had very low safety significance (Green) because it was not a design issue resulting in loss of function, did not represent an actual loss of a system safety function, did not result in exceeding a Technical Specification allowed outage time, and did not affect external event mitigation. There is no crosscutting area assigned to the performance deficiency because the inadequacy in the procedure is not indicative of current plant performance |
