| Title | Deficiencies with RCIC Room Heat Up Analyses |
| Description | The inspectors identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion III, Design Control, having very low safety significance for the failure to include all of the applicable heat loads in the Reactor Core Isolation Cooling (RCIC) Room heat up calculation and not having a calculation of record for the RCIC Room heat up under a station blackout (SBO) scenario. The licensee entered this issue into the corrective action program and performed preliminary calculations to verify that the issues did not exceed any design limits. The performance deficiency was determined to be more than minor because it was associated with the Mitigating Systems Cornerstone attribute of Equipment Performance, and affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The finding screened as very low safety significance because the licensee determined the RCIC Room cooler was capable of removing the additional heat load; and RCIC Room temperature remained within the design limits without the room cooler during a SBO scenario. The inspectors determined that this finding did not represent current licensee performance and no cross-cutting aspect was assigned. |
