SUBJECT:
NRC REGION 1 INTEGRATED INSPECTION REPORT NOS. 50 317/97-05
AND 50-318/97-05 AND NOTICE OF VIOLATION
Dear Mr. Cruse:
This report transmits the findings of the safety inspection conducted by NRC inspectors at
l
the Calvert Cliffs Nuclear Power Plant from July 27,1997 to September 13,1997. The
enclosed report presents the results of that inspection. At the conclusion of the
inspection, these findings were discussed with Mr. Katz and others of your staff.
I
Overall, the NRC has concluded that your facility was operated in a safe manner. During
the period, plant operators tripped a circulating water pump and rapidly reduced Unit 1
power in response to jellyfish clogging a plant intake screen. At the end of the period,
Unit 1 was shutdown to initiate a repair of a reactor coolant pump seal. In both cases, the
reactor was controlled in an effective manner with an appropriate focus on safety.
Engineering support in monitoring the reactor coolant pump seal performance and -
supporting the seal replacement outage was notable.
Based on the results of this inspection, the NRC has determined that two violations of NRC
requirements occurred. These violations are cited in the enclosed Notice of Violation
(Notice) and the circumstances surrounding them are described in detail in the enclosed
inspection report. The violations are of concern because they involve a failure to promptly
identify and correct problems before equipment failures occurred. In the first case, actions
were not taken to preclude repeated failures of emergency lights even though some
lighting failures were observed each time the lights were tested. Although the rervice life
for some emergency lighting batteries was reduced by temperature, tracking of service life
had not been effective in preventir.g repeated failures. The second violation involved a
failure to identify and correct problems with compression fittings used in plant systems,
including the reactor coolant pressure boundary. As identified by your staff, failures of
compression fittings first occurred in 1992, with additional problems in 1993 and 1995.
- However, corrective actions were delayed and preventive action was not taken until af ter
the failure of a pressurizer pressure instrument occurred on May 29,1997.
You are required to respond to this letter and should follow the instructions specified in the
enclosed Notice when preparing your response. The NRC will use your response, in part,
to determine whether further enforcement action is necessary to ensure com,Wance with
regulatory requirements.
