| Title | Ultimate Heat Sink Cooling Tower - Incorrect Action Criteria in Control Room Evacuation Procedure |
| Description | The inspectors identified a non-cited violation of Technical Specification 5.4.1(d), ?Procedures,? which states, in part, that written procedures shall be established, implemented, and maintained covering fire protection program implementation. Specifically, prior to October 10, 2013, Procedure OTO-ZZ-00001, ?Control Room Inaccessibility,? Revision 38, steps D31 and D32, directed operators to use incorrect process indication and action criteria to diagnose and prevent icing conditions in the cooling tower after the control room was evacuated. This condition was entered into the corrective action program as Callaway Action Request 201307709. As a result, the licensee revised the action criteria to direct the operators to take action to prevent icing in the cooling tower. The inspectors determined that the failure of Procedure OTO-ZZ-00001 to contain the appropriate criteria for operator action to control the ultimate heat sink cooling tower bypass valve after a control room evacuation was a performance deficiency. The inspectors determined that the performance deficiency was associated with the Mitigating Systems Cornerstone and was more than minor, and therefore a finding, because, if left uncorrected, it would have the potential to lead to a more significant safety concern. Specifically, the action criteria would not direct the operators to correctly diagnose, prevent, or mitigate icing in the ultimate heat sink cooling tower after a control room evacuation. Using NRC Manual Chapter 0609, Appendix F, ?Fire Protection Significance Determination Process,? the inspectors determined that the finding had very low safety significance (Green) because this finding would not have prevented the reactor from reaching and maintaining safe shutdown. This finding was not assigned a cross-cutting aspect because the most significant contributor was not reflective of current licensee performance. |
