| Title | Inadequate Corrective Action on Human Performance Issues Results in Two Trains of Auxiliary Feedwater Inoperable |
| Description | A self-revealing NCV of 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, was identified for Ginnas failure to implement adequate compensatory corrective actions associated with a series of human performance issues and valve mispositioning events. The corrective actions were inadequate in that Ginna failed to prevent an improperly tagged closed auxiliary feedwater (AFW) valve which resulted in two trains of AFW inoperable. Corrective actions included compensatory actions which required 100 percent peer checks on all tagout applications, a separate pre-job brief for the independent verification of tagouts, and for a senior reactor operator to observe the independent verification portion of the tagout process. This finding was entered into Ginnas corrective action program (CR-2012-0294). This finding is more than minor because it is associated with the human performance attribute of the Mitigating Systems cornerstone, and it adversely 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). The inspectors determined this finding is of very low safety significance because it was not a design or qualification deficiency, did not involve an actual loss of safety function for greater than its technical specification allowed outage time, and did not screen as potentially risk significant due to a seismic, flooding, or severe weather initiating event. This finding has a cross-cutting aspect in the area of problem identification and resolution because Ginna did not take appropriate corrective actions to address safety issues and adverse trends in a timely manner commensurate with their safety significance and complexity. Specifically, Ginna did not implement appropriate compensatory actions to address a weakness in procedure use and adherence by operations personnel |
