| Title | Inadequate Procedure for Powering Credited Components for Fire in Cable Vault & Tunnel |
| Description | The inspectors identified a Green non-cited violation (NCV) of Technical Specification 5.4.1, Procedures, in that the Unit 1 post-fire safe shutdown (SSD)procedure 1-FCA-3, Cable Vault and Tunnel Fire, Revision 20, was not consistent with the safe shutdown analysis (SSA) for FA 3-1. Specifically, 1-FCA-3 directed operators to plug a ventilation fan into a receptacle that is powered from an electrical bus that had been previously de-energized in a prior step of the procedure. In another example, 1-FCA-3 did not give operators guidance for swapping the power supply of the auxiliary monitoring panel in the Fuel Handling Building. The licensee entered this issue into their corrective action program, and issued a new revision of1-FCA-3.This finding is more than minor because it is associated with the procedure quality attribute of the Mitigating Systems cornerstone, and it affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The inspectors assessed the finding using Inspection Manual Chapter (IMC) 0609, Appendix F, Fire Protection Significance Determination Process. The finding was assigned a low degradation rating in Phase 1 because it was determined to be a procedural deficiency that is compensated by operator experience and/or familiarity. The inspectors reviewed guidance contained in IMC 0305 to determine if any crosscutting aspects existed. This finding has a cross-cutting aspect in the resources component of the human performance area H.2(c) because the procedure was not complete and up to date in accordance with the SSA.
