Title | Licensee-Identified Violation |
Description | TS 6.8.1, Procedures, requires, in part, that written procedures shall be established, implemented, and maintained covering the applicable procedures recommended in RG 1.33. Contrary to this requirement, on May 15, 2013, Dominion failed to correctly implement procedure OP 3312A, Containment Personnel Air Lock Operation, 3CS*Hatch1, to ensure that the equalizing valve for the Unit 3 outer access door was maintained in a closed configuration while the inner access hatch was opened. As a result, a loss of containment integrity occurred when the plant was in mode 4. The operators entered TS 3.6.1.1 and verified the equalizing valve had been closed, thereby restoring containment integrity within one hour required as required by TS 3.6.1.1 and 3.6.1.3. 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 this issue into their CAP as CR 515704 and subsequently reported the loss of safety function to the NRC in LER-2013-005-00 as required under 10 CFR 50.73(a)(2)(v)(C). |
