| Title | Licensee-Identified Violation |
| Description | TS 3.6.6.2, Secondary Containment, requires secondary containment to be operable. If inoperable, secondary containment shall be restored to operable within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or the unit shall be in at least HOT STANDBY within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in COLD SHUTDOWN within the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />. Contrary to this requirement, from 1:57 AM on November 17, 2012, when security performed its test of the Unit 3 roll-up door, until 12:51 PM on November 21, 2012, when the door was fully closed (4 days, 9 hours1.041667e-4 days <br />0.0025 hours <br />1.488095e-5 weeks <br />3.4245e-6 months <br />, 12 minutes), secondary containment was inoperable. Because Dominion did not recognize this condition as rendering secondary containment inoperable until January 28, 2013, they did not take action in accordance with their TS. The inspectors determined that the finding was of very low safety significance (Green) in accordance with IMC 0609, Appendix A, The Significance Determination Process for Findings at Power. Dominion entered the issue into their CAP as CR 507822 and reported the loss of safety function and condition prohibited by TS as required under 10 CFR 50.73(a)(2)(v)(C) and 10 CFR 50.73(a)(2)(i)(B). |
