SUBJECT: NRC INSPECTION REPORT 50-298/96-26 AND NOTICE OF VIOLATION
Dear Mr. Horn:
On November 30,1996, the NRC completed an inspection at your Cooper Nuclear Station
facility. The enclosed report presents the results of that inspection.
This report documents an NRC-identified violation of NRC requirements in that your staff
failed to properly implement a Technical Specification surveillance requirement to evaluate
the potential for common cause failure of the emergency diesel generators. The process
for performing these evaluations was not documented and was not clear to your staff.
Subsequent evaluations demonstrated that for the two examples of the violation, neither
resulted in the redundant diesel being inoperable. However, a weak common cause
'
evaluation process could result in failure to identify a common mode vulnerability
concerning diesel generator failure, a situation with considerable safety significance.
j
Also, this report documents three instances where deficient maintenance work packages
were submitted to the control room to be released for work. In two of these instances,-
control room operators identified the deficiencies and returned the work packages for
correction. In the third instance, control room operators did not identify the deficiency and
only NRC inspector questioning prevented a prohibited system lineup. These occurrences
show that control room operators are being challenged by the poor quality of maintenance
work packages. Your attention in this area is warranted.
In accordance with 10 CFR 2.790 of the NRC's " Rules of Practice," a copy of this letter,
its enclosure (s), and your response will be placed in the NRC Public Document Room.
Sincerely,
J. E. Dyer, Director
Division of Reactor Projects
