On March 30, 2023, the NRC issued a notice of violation (Notice) and Proposed Imposition of Civil Penalty to Louisiana Energy Services (licensee) for a Severity Level (SL) II problem. The SL II problem involved the licensee’s failure to (1) implement the appropriate item relied on for safety (IROFS) controls as required by 10 CFR 70.61(b) for a credible high consequence accident sequence included in the Integrated Safety Analysis; and (2) maintain independence between two IROFS during a barrier breach resulting in a degraded IROFS contrary to requirements in 10 CFR 70.61(b).
