| Title | Failure to Satisfy 10 CFR 50.73 Reporting Requirements for an Unanalyzed Condition |
| Description | The inspectors identified a NCV of the NRCs reporting requirements in 10 CFR 50.73, Licensee Event Report System. The licensee failed to submit a required Licensee Event Report (LER) within 60 days after the discovery of a condition that resulted in the nuclear power plant being in an unanalyzed condition that significantly degraded plant safety, a condition that could have prevented the fulfillment of the safety function of structures or systems needed to mitigate the consequences of an accident, and a condition prohibited by the plants Technical Specifications (TSs). Specifically, the licensee failed to either make a separate LER or further revise an existing LER with additional information to fully describe a known unanalyzed condition affecting its ability to mitigate a design basis external flooding event based on additional problems it had discovered, the corrective actions taken to correct the condition, the safety significance, and the date when full compliance was restored. The licensee initiated a corrective action to supplement an existing LER to describe the additional issues it identified that affected its external flooding mitigation plan and to specify the noncompliance window as February 29, 2012 through January 31, 2014. Consistent with the guidance in IMC 0612, Power Reactor Inspection Reports, Appendix B, Issue Screening, dated September 7, 2012, the inspectors determined the performance deficiency was not of more than minor significance based on No answers to the more-than-minor screening questions. In accordance with Section 6.9.d.9 of the NRC Enforcement Policy, this violation was categorized as Severity Level IV because the licensee failed to report as required by 10 CFR 50.73(a)(1). No cross-cutting aspect is associated with this traditional enforcement violation because the associated performance deficiency was determined to be of minor significance and therefore not a finding. |
