| Title | Licensee-Identified Violation |
| Description | Technical Specification 6.8.1 requires, in part, that written procedures shall be established, implemented, and maintained covering the applicable procedures recommended in Regulatory Guide1.33. Contrary to this, Dominion\'s procedure MP2704U, Containment Personnel Airlock, was inadequate because it was not established with sufficient detail to complete interlock restoration. As a result, the containment airlock interlock was not properly reset at the end of the refueling outage on November 13, 2009. On December 2, 2009, containment integrity was not maintained when the improperly reset interlock allowed both airlock doors to be briefly open during a containment entry while Unit 2 was at 100 percent power. Dominion immediately closed the door and entered the issue into their corrective action process, CR 360277. The finding is of very low safety significance because both airlock doors were only open briefly 1 minute) and there were no other degraded plant conditions that would have created a safety concern during the time the airlock doors were open |
