On July 17, 2013, the NRC issued a Notice of Violation to Entergy Nuclear Operations, Inc. (Entergy) for a Severity Level III problem involving two violations of NRC requirements associated with licensed reactor operator medical examinations and reporting at the Pilgrim Nuclear Power Station (PNPS). The first violation involved Entergy's failure to ensure licensed operators at PNPS meet medical prerequisites for performing NRC-licensed operator activities and Entergy's failure to obtain prior NRC approval, as required by 10 CFR 55.3, 10 CFR 55.31 and 10 CFR 55.23. Specifically, on various dates, licensed reactor operators performed duties without meeting medical prerequisites (blood pressure limits and stamina tests) and without prior NRC approval. The second violation involved Entergy's failure to provide the NRC with information that is complete and accurate in all material respects, as required by 10 CFR 50.9. Specifically, Entergy submitted NRC Form-396s for renewal of two reactor operator licenses that certified that the operators met the medical requirements of ANSI/ANS 3.4-1983, when, in fact, the facility licensee had not verified, via conducting a stamina test, that the operators had met the requirements.
