| Title | |
| Description | The inspectors identified a Green NCV of Technical Specification (TS) 6.8.1, Procedures, for the failure to accurately maintain the EOPs and Abnormal Operating Procedures (AOPs) by not including operating restrictions that had been promulgated as a temporary order (Standing Order (SO) 14-04) regarding the limitation of the closure sequence and rate for the Turbine-Driven Auxiliary Feedwater (TDAFW) pump flow control valves (3FWA*HCV36A, B, C and D). Dominions immediate corrective actions included approving a revision to the appropriate AOPs and EOPs to incorporate the throttling restrictions. This finding is more than minor because it is associated with the procedure quality attribute of the Mitigating Systems cornerstone and affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage). Specifically, Dominion did not incorporate operating restrictions on the throttling rate of the TDAFW pump flow control valves into the post-event procedures (AOPs and EOPs). In accordance with IMC 0609.04, Initial Characterization of Findings, and Appendix A, Exhibit 2, The Significance Determination Process for Findings at Power, the inspectors determined the finding is of very low safety significance (Green) because the performance deficiency involved a procedural deficiency but did not involve an actual loss of safety function, represent an actual loss of safety function of a single train for greater than TS allowed outage time, did not screen as potentially risk significant due to a seismic, flooding, or severe weather initiating event, and did not represent an actual loss of function of an non-TS train of equipment designated as high safety significant. This finding has a cross-cutting aspect in the area of Problem Identification and Resolution, Resolution, in that Dominion did not take effective corrective actions to address issues in a timely manner commensurate with their safety significance. Dominion determined that it was not necessary to incorporate the AFW throttling restrictions into the EOPs or AOPs. |
