SUBJECT:
D. C. COOK INSPECTION REPORT 50-'315/98008(DRP); 50-316/98008(DRP)
Dear Mr. Sampson:
On April27, 1998, the NRC completed an inspection at your D. C. Cook Units 1 and 2 reactor
facilities. The enclosed report presents the results of that inspection.
During the 6-week period
covered by this inspection report, the inspectors observed that the plant was maintained
shutdown in a safe manner and that shutdown activities were focused on safety.
Based on the results of this inspection, three violations of NRC requirements were identified by
the NRC. The violations are cited in the enclosed Notice of Violation (Notice) ~ and the
circumstances
surrounding them are described in detail in the subject inspection report. The first
violation involved a failure to follow procedure by contract maintenance workers. The violation is
of concern because of the failure of the contract workers to verify the proper bolting configuration
on the
1 CD emergency diesel generator.
The improper bolting configuration could have led, to a
failure on that engine similar to the exhaust manifold bracket failure which caused the 2 AB
emergency diesel generator to become inoperable.
The second violation involved the
inadequate root cause determination by your staff regarding the missing jam nuts.
Your staff's
assessment
determined that the root cause could not be identified, while the NRC inspectors
determined the root cause was due to poor contractor performance.
The third violation involved
the failure of the Unit 2 operators to use a procedure designated as "Continuous Use" at the job
site. The Unit 2 operators were not sure which general plant procedures, ifany, were in use
while operating in Mode 5, and this resulted in the operators failing to continuously use the
procedure as required.
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 compliance with regulatory
requirements.
