| Title | Lack of 50.59 Evaluation for Substitution of Manual Actions for Automatic Start Signals on the a Motor Driven AFW Pump |
| Description | The inspectors identified a Severity Level IV NCV of 10 CFR 50.59(d)(1) for the licensees failure to document an evaluation which provides a basis for the determination that the change, test, or experiment did not require a license amendment. Specifically, for Revision 4 and Revision 101 of procedure 1/2BwOA ELEC-4 Loss of Off-site Power the licensee failed to provide an evaluation as to why replacing an automatic pump start function with a manual action (e.g., placing the A motor driven auxiliary feed pump in pull out) did not present more than a minimal increase in the likelihood of occurrence of a malfunction of a structure system or component important to safety previously evaluated in the Updated Final Safety Analysis Report. The licensee entered this issue into the corrective action program, and initiated actions to complete a 10 CFR 50.59 evaluation to determine if these procedure changes were acceptable without a license amendment. Because the licensees procedure changes implemented the appropriate Technical Specification requirements, this issue did not affect the operability of the auxiliary feedwater system. Because the issue potentially impacted the NRCs ability to perform its regulatory function, this finding 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 procedural change, that affected the Updated Final Safety Analysis Report described design function of equipment important to safety, would not have ultimately required NRC prior approval. Based upon this Phase 1 screening, the inspectors concluded that the issue was of very low safety significance. |
