| Title | Inadequate Procedure Guidance to Diagnose and Align RCP Seal Cooling |
| Description | \"The team identified a Green non-cited violation of technical specification 5.4.1.d for failure to provide adequate procedure directions in 3-AOP-SSD-1, Control Room Inaccessibility Safe Shutdown Control, Rev. 6, for operators to properly determine if a loss of cooling to the reactor coolant pump (RCP) seal had occurred due to spurious closure of motor operated valves in the component cooling water (CCW) system. This finding was more than minor because it affected the procedure quality attribute of the Initiating Events cornerstone objective to limit the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. Specifically, establishing adequate guidance to diagnose and align RCP seal cooling functions is important to limit the likelihood of an RCP seal loss of coolant accident. The team assessed this finding in accordance with NRC IMC 0609, Appendix F, Fire Protection Significance Determination Process. This finding screened to very low safety significance (Green) in Phase 1 of the SDP because it was assigned a low degradation rating. The team determined that this finding has a cross-cutting aspect in the area of human performance because Entergy did not provide adequate procedure guidance to diagnose and align RCP seal cooling functions adequately to preclude seal leakage rates in excess of Appendix R Safe-Shutdown evaluation for a control building fire scenario.
