| Title | |
| Description | The team identified a finding of very low safety significance involving two examples of a non-cited violation (NCV) of 10 CFR 50, Appendix B, Criterion III, Design Control. Specifically, in one example, the licensee failed to establish design control measures to verify or check the adequacy of critical design inputs for the calculation that determined that the Unit 3A and 3B emergency diesel generators (EDGs) would be operable at outside ambient temperatures at or below 75oF if the 3A and 3B Diesel Building Ventilation Fans are out of service as allowed by procedures. In the second example, the licensee failed to ensure the adequacy of design for the auxiliary feed water steam generator flow control valves. The finding was more than minor because it was associated with the Design Control attribute of the Mitigating System Cornerstone and affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The team assessed the finding using the SDP and determined that the finding was of very low safety significance (Green) since it was a design deficiency determined not to have resulted in the loss of safety function. Specifically, in both cases, the licensee had not operated in a condition for which the design deficiencies in question were relied upon for operation. Both examples had been entered in the licensees corrective action system. The finding was evaluated for cross-cutting aspects and none were identified. (Sections 1R21.2.3 and 1R21.2.4 |
