| Title | Failure to Report Deficiencies as Required by 10 CFR 50.46 |
| Description | SL IV. The inspectors identified a Severity Level IV Violation of 10 CFR Part 50.46, Acceptance Criteria for Emergency Core Cooling Systems for Light -Water Nuclear Power Reactors. Specifically, the licensee failed to report the effects of the errors in the 5 LBLOCA Evaluation Model for the Unit 1 emergency core cooling systems. The inspectors determined that the failure to estimate and report the errors in the LB LOCA analyses were contrary to the requirements of 10 CFR 50.46 and was a performance deficiency. The performance deficiency was determined to be minor because the failure to report was not willful, did not impact a performance indicator, was not a material condition issue which could lead to a more significant safety issue, and did not impact the Mitigating Systems cornerstone objectives. The inspectors determined the failure to report was a Severity Level IV violation in accordance with Section 6.9 of the Enforcement Policy. A cross -cutting aspect was not assigned since the performance deficiency is minor. |
