Title | Licensee-Identified Violation |
Description | 10 CFR 50.65(a)(4) requires in part, that the licensee shall assess and manage the increase in risk that may result from the proposed maintenance activities before performing maintenance. Contrary to the above, on September 22, 2008, licensee personnel failed to adequately manage the risk associated with the initiation of planned testing activities after emergent equipment failures. Specifically, at approximately 11:00 a.m., on September 22, 2008, Unit 2 Train A RHR failed and shortly thereafter, the breaker to the valve isolating auxiliary feedwater to SG 22 was opened resulting in an unplanned Orange path entry. This condition existed for approximately two hours and 13 minutes before licensee personnel recognized the condition and restored power to the AFW isolation valve. The licensee entered this issue into their corrective action program as CAP 1162470 |
