A NRC-identified finding was identified for the failure to follow the sites corrective action program (
CAP) procedure which required the initiation of a
PIP for a degraded 2B
emergency diesel generator (
EDG) Bellofram seal. The degraded Bellofram seal contributed to the improper setup of the 2B
EDG governor actuator which resulted in the 2B
EDG not achieving the required 105 percent full power output. The performance deficiency was more than minor because it was associated with the human performance attribute of the
Mitigating Systems cornerstone and adversely impacted the cornerstone objective in that the capability of the
EDG to provide continuous and adequate load margin was affected. The finding was of very low safety significance because it did not represent an actual loss of safety function of the system or train. The finding was directly related to the cross-cutting aspect of implements the
CAP with a low threshold in the Corrective Action Program component in the area of the Problem Identification and Resolution because the licensee did not enter the condition into the
CAP.
