| Title | Acceptability of Proceduralized Departures from TS Requirements Without NRC Approval in AOP-M.09 |
| Description | An unresolved item (URI) was identified for NRC review of whether the licensees preplanned and proceduralized departures from TS requirements, without obtaining NRC approval, constituted a non-compliance with NRC regulations. The licensee implemented a new abnormal operating procedure, (AOP)- M.09, Loss of Charging, Rev. 0, to address the loss of one or both centrifugal charging pumps (CCPs) in Modes 1-4. This procedure replaced a portion of the guidance in Annunciator Response Procedure 1,2-AR-M6-C Window D-3 (Charging Line Flow Abnormal alarm). The licensee determined that a loss of both CCPs would result in the loss of RCS boration and RCS makeup (charging) capability. AOP-M.09 contains contingency actions for reducing RCS pressure and using a Safety Injection (SI) pump to inject to the RCS to borate and maintain pressurizer level. At Mode 4, AOP-M.09 requires an evaluation of 50.54(x) criteria and further directs use of the SI pumps. Injection using the SI pumps in Mode 4 would violate the requirements of TS LCO 3.4.12, Low Temperature Overpressure Protection System, which requires that the SI pumps be incapable of injection. Summary: This issue will remain open for NRC review of whether the licensees preplanned and proceduralized departures from TS requirements, without obtaining NRC approval, constitute a non-compliance with NRC regulations. It will be identified as URI 05000327,328/2008005-02: Acceptability of Proceduralized Departures from TS Requirements Without NRC Approval in AOP-M.09 |
