| Title | Licensee-Identified Violation |
| Description | Fire Protection License Condition 2.C.14, Fire Protection Program (Generic Letter 86-10), states that the licensee shall implement and maintain in effect all provisions of the approved fire protection program as described in Section 9.5.1 and Appendix F of the final safety analysis report. Final safety analysis report, Table F.3-2, Comparison with the Specific Commitments to 10 CFR Part 50, Appendix R, Section III.G.2, Fire Protection of Safe Shutdown Capability, states, in part, that cables or equipment, including associated non-safety circuits that could prevent operation or cause maloperation due to hot shorts, open circuits, or shorts to ground of redundant trains of systems necessary to achieve and maintain hot shutdown conditions are free of fire damage. Contrary to this, the licensee failed to ensure that cables or equipment that could prevent operation or cause maloperation due to hot shorts, open circuits, or shorts to ground of redundant trains of a systems necessary to achieve and maintain hot shutdown conditions are free of fire damage. The licensee documented in Action Request AR 00332688 that during a self-assessment for fire protection and post-fire safe shutdown programs, a multiple spurious operations scenario related to flow diversion from the suppression pool to the condensate storage tank was missed. It was identified that fire-induced circuit damage to cables for HPCS-V-10, HPCS-V-11, HPCS-V-15, HPCS-P-1, and HPCS-P-3 would cause a condition that could challenge operations achieving and maintaining safe shutdown conditions. The team screened the violation using Inspection Manual Chapter 0609, Appendix F, requiring a Phase 2 screening as described in Attachment 1. The team concluded that the violation screens to very low safety significance because the ignition sources screen out during the Phase 2 significance determination process. |
