| Title | Improper Unit 2 Zone G Modification |
| Description | A self-revealing finding was identified for the licensees failure to follow EDM-141, Procurement Specifications for Services. The licensee did not identify the blocking feature for the instantaneous underfrequency protective function in both the vendor specification and the supporting information provided to the vendor. The offsite power supply to Unit 2 would have been lost anytime there was a generator trip from high power and offsite power was provided from Unit 2 without this blocking feature. The licensee corrected the blocking function prior to unit restart. The performance deficiency was more than minor because, if left uncorrected, it would result in a more significant safety concern in that Unit 2 would have had a LOSP anytime the generator tripped from a high power condition. The inspectors determined the finding was of very low safety significance because the programming error was corrected prior to unit restart; therefore, there was no loss of safety function. The same cross-cutting aspect for the Unit 1 finding also applies to this finding; therefore, no separate cross-cutting aspect will be assigned to this finding. |
