Title | Licensee-Identified Violation |
Description | Title 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, states, in part, that measures shall be established to assure that conditions adverse to quality are promptly identified and corrected. In the case of significant conditions adverse to quality, the measures shall assure that the cause of the condition is determined and corrective action taken to preclude repetition. Contrary to the above, between December 5, 2007, and October 13, 2010, the licensee did not preclude repetition of a significant condition adverse to quality. Specifically, corrective actions to prevent recurrence of seven Unit 3 containment spray nozzles obstruction due to boric acid residue were inadequate. This finding was entered into the licensees corrective action program as PVAR 3548317. This finding is of very low safety significance because it did not result in a loss of safety function, and actual loss of safety function of a single train for greater than it technical specification allowed outage time, or screen as potentially risk significant due to seismic, flooding, or severe weather initiating event. |
