On April 10, 2015, the NRC issued a Notice of Violation to Exelon Generation Company, LLC for a Severity Level III Problem involving two related violations identified as a result of an inspection at its Nine Mile Point Nuclear Station (NMP). The first violation involved the failure on multiple occasions to notify the NRC within 30 days of medical conditions of licensed reactor operators (ROs) and senior reactor operators (SROs) that involved permanent disabilities/illnesses as required by 10 CFR 50.74(c). Specifically, between June 2001 and September 2014, NMP staff was informed that operators were taking prescribed medication for such conditions as hypertension, post-traumatic stress disorder, attention deficit disorder, and asthma. NMP did not report these permanent medical conditions to the NRC when they submitted NRC Form 396 as part of the operators' license application process. Additionally, NMP did not restrict these same licensed ROs and SROs from performing licensed duties when the individuals had disqualifying medical conditions, in accordance with 10 CFR 55.25. The second violation involved the submittal by NMP of information to the NRC that was not complete and accurate in all material respects as required by 10 CFR 50.9. Specifically, on multiple occasions between September 2002 and February 2012, NMP submitted applications for operators that certified the medical fitness of the applicants and that did not identify any needed license operator restrictions regarding disqualifying medical conditions or related prescription medication. Each of the applicants had medical conditions that did not meet the minimum standards of 10 CFR 55.33(a)(1). Subsequently, the NRC based in part on this inaccurate information, issued reactor operator licenses without the required restricting license conditions.
