| Title | Licensee-Identified Violation |
| Description | TS 3.0.4 requires, in part, that when a Limiting Condition for Operation is not met, entry into a mode or other specified condition shall only be made when the associated actions to be entered permit continued operation in the mode for an unlimited period of time. TS 3.7.1.6 requires that each FWIV be operable in Modes 1-3 and the associated ACTIONS for Mode 1 operation do not allow operation for an unlimited period of time. Contrary to the above, on September 25, 2010, due to inadequate procedural guidance, operators did not ensure that one of the three FWIVs air accumulator pressure was above the minimum for operability when Mode 1 was entered from Mode 2. This condition existed for seven minutes until the minimum pressure for operability was attained in the FWIV air accumulator. The violation was determined to be of very low safety significance because of the short duration that pressure was below the minimum for operability and subsequent FWIV testing determined that the FWIV remained capable of performing its design function at the reduced air accumulator pressure. The licensee planned to revise GOP-4A, Power Operation Mode 1 Ascending, to ensure verification that all FWIV actuator pressures are above the minimum pressure for operability prior to allowing entry into Mode 1. The licensee identified and addressed this issue in their corrective action program as CR-10-03766 |
