| Title | Inadequate procedures to control the plant from the dedicated shutdown panel |
| Description | On August 11 and 13, 2010, the inspectors walked down the dedicated shutdown system abnormal operating procedure 20.000.18. The inspectors identified an unresolved item (URI) for inadequacy of the procedures utilized to control the plant from the dedicated shutdown panel. Specifically, the inspectors identified that at the minimum staffing complement of non-licensed nuclear operators as defined in MOP03, Section 3.4.1, the outside rounds operator, who is the available nuclear operator designated to fulfill the position as the nuclear operator for dedicated shutdown, would not be able to complete the required actions to restore reactor pressure vessel makeup within 29 minutes, as required by the licensees feasibility study. At minimum staffing complement of non-licensed nuclear operators as defined in MOP03, Section 3.4.1, the outside rounds operator is the only available nuclear operator during a fire emergency that would require utilization of the dedicated shutdown panel for safe shutdown. The outside rounds operator could be at a location outside the protected area at the initiation of the abnormal event. The fire protection engineering evaluation (FPEE) 05-0012 assumes initial conditions based upon the safe shutdown nuclear operators starting from the main control room and proceeding with the non-supervisory reactor operator assigned to the dedicated shutdown panel and commencing implementation of the abnormal operating procedure 20.000.18. A delay of 7 minutes and 22 seconds was estimated by the licensee for the time it would take the outside rounds operator to proceed to the dedicated shutdown panel. Thus, the time to restore reactor pressure vessel makeup, which is defined as required by the FPEE within 29 minutes of initiation of the dedicated shutdown panel, would be estimated to be 33 minutes (rounded). It appears the Standard Operating Procedure 20.000.18 is inadequate in meeting the objective to restore reactor pressure vessel makeup. The licensee documented the issue in Card 10-27645. There is no current safety concern as an extra operator is on shift to cover the requirements. Further, procedures are being revised to ensure the operator is inside of the power block. This item is being held as an unresolved item (URI 05000341/2010004-01) pending evaluation of the timing and manning issues by the licensee. |
