Title | Failure to Correct Multiple Conditions Adverse to Quality |
Description | The team identified a noncited violation of 10 CFR Part 50, Appendix B, Criterion XVI, \"Corrective Action,\" for the failure to preclude repetition of a significant condition adverse to quality. Specifically, licensee corrective actions to prevent recurrence of voiding in the low pressure safety injection system were not sufficient to prevent nitrogen voids from challenging system operability. This violation was entered into the licensee\'s corrective action program as CR-WF3-2010-3050
The finding is more than minor because, if left uncorrected, the finding would have the potential to become a more significant safety concern (i.e., continued challenges to system operability). Using Manual Chapter 0609.04, \"Phase 1 Initial screening and Characterization of Findings,\" the issue screened as having very low safety significance because it: (1) was not a design or qualification deficiency; (2) did not represent a loss of safety function; (3) did not represent an actual loss of a single train of equipment for more than its technical specification allowed outage time; (4) did not represent a loss of risk significant non-technical specification equipment; and (5) did not screen as potentially risk significant due to a seismic, flooding, or severe weather initiating event. This finding had a crosscutting aspect in the corrective action component of the problem identification and resolution area in that the licensee failed to thoroughly evaluate the problem, such that the resolutions addressed the cause [P.1 (c)]. As a result, the resolutions failed to prevent recurrence of the problem. |
