| Title | Licensee-Identified Violation |
| Description | 10 CFR 50, Appendix B, Criterion XVI, states, in part, that measures shall be established to assure that conditions adverse to quality, such as failures, malfunctions, deficiencies, deviations, defective material and equipment, and nonconformances are promptly identified and corrected. Contrary to the above, for the January 30 Unit 2 pressurizer heater failure, Dominion determined the root cause of the event was the continued failure of pressurizer heaters due to manufacturing defects associated with replacement heaters and determined this was a repeat failure because CAPRs from a previous event in 2009 were not complete. Dominion entered the issue into the CAP as CR 538495. The inspectors determined that this finding was of very low safety significance using IMC 0609, Appendix A, because the finding did not cause a reactor trip and the loss of mitigation equipment relied upon to transition the plant from the onset of the trip to a stable shutdown condition. |
