Title | Failure to Prevent Repetitive Voiding in the Low Pressure Safety Injection System |
Description | The team identified a noncited violation of 10 CFR Part 50, Appendix B, Criterion XVI, \"Corrective Action,\" for the failure to ensure that conditions adverse to quality are promptly corrected. Specifically, multiple examples of boric acid leaks were identified in the corrective action program where corrective actions had not yet been taken or had been ineffective. At least ten of these active boric acid leaks are five to seven years old
The failure to promptly correct boric acid leaks is a performance deficiency. The finding is more than minor because, if left uncorrected, the finding could become a more significant safety concern (Le., potential for damage to carbon steel components or inhibiting the safety-function of others). 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 problem identification and resolution, corrective action component [P.1 (d)] in that the licensee failed to effectively correct identified boric acid leaks in a timely manner. |
