SUBJECT: NRC INSPECTION REPORT NO. 50-263/97003(DRP) | |||
Dear Mr. Wadley: | |||
On April 11,1997, the NRC completed an inspection at your Monticello reactor facility. | |||
The enclosed report presents the results of that inspection. | |||
During the seven week period covered by this inspection period, your conduct of activities ! | |||
at the Monticello facility was acceptable. Recent Generation Quality Service audit findings ! | |||
demonstrated a good questioning attitude and follow through with identified concerns. ' | |||
However, we noted that some problems occurred during maintenance activities. One such , | |||
activity resulted in a loss of voltage to an essential electrical bus and starting of | |||
emergency diesel generators. Electricians failed to remove a temporarily-installed meter | |||
from logic circuitry. In additioni the inspectors identified that the operators were unaware | |||
.the #13 emergency service water pump had been operating for two days. This oversight | |||
existed through four shift turnovers between three operating crews. This raises concern i | |||
over the effectiveness and thoroughness of operator walkarounds and shift turnovers. Our | |||
review of the circumstances leading to this event is not complete and will be discussed in | |||
a future inspection report. We will contact you in the near future to schedule a | |||
management meeting to discuss these and other recent operation and surveillance issues. | |||
A predecisional enforcement conference was conducted on March 5,1997, to discuss the ' | |||
apparent violation identified in inspection Report No. 50-263/96009 regarding an | |||
i inadequate safety evaluation related to ECCS pump configuration (EA 97-032). You will | |||
be informed of our decision regarding enforcement action via separate correspondence. | |||
