| Title | Failure to Perform 10 CFR 50.59 Evaluations for Changes in Assumed Operator Times |
| Description | The inspectors identified a Severity Level IV NCV, having very low safety significance, of 10 CFR 50.59, Changes, Tests, and Experiments, from the licensees failure to provide a documented basis for determining that changes in how operator response times for postulated steam generator tube ruptures were credited in accident analyses did not require prior NRC approval. This issue was entered into the licensees corrective action program. Because the issue affected the NRCs ability to perform its regulatory function, this issue was evaluated using the traditional enforcement process. The finding was determined to be more than minor because the inspectors could not reasonably determine that the changes would not have ultimately required NRC prior approval. The finding was determined to be of very low safety significance because there was evidence that operator actions could be performed in time to prevent overfill of a steam generator. This finding had a cross-cutting aspect in the area of Human Performance because the licensee failed to ensure that training was adequate to assure nuclear safety (H.2(b)) in that training for 10 CFR 50.59 safety evaluations and screenings was deficient. |
