D. L.'Caphton, Senior Reactor _Inspsetor Region 1 Operations Branch JERSEY CENTRAL POWER AND LIGHT COM/ANY ' OYSTER CREEK' (DN 50'219)
LICENSING INTERPRETATION OF TECHNICAL SPECIFICATION 3.7 C.2 The' referenced Tech Spec states _in part, "that if one diesel generator becomes inoperable during power operation, repairs-shall be initiated immediately and the other diesel shall be operated _at least one hour every twenty-four hours The reactor may remain in operation for a ~ period not to e:<ceed' seven days in any thirty day period if a diesel generator is out of service.
The Oyster Creek site informed me yesterday,. September 18, 1975, that one diesel generator had been removed from service for annual maintenance, which would be completed this date following five days of down time. The question was asked as to how Region 1 viewed this Technical Specification with respect to returning the referenced diesel to service and then proceding with. maintenance-on the other diesel generator.
If the_licenseu performed the annual _ maintenance on both ' units it is likely that the cumulative time a diesel generator would be out of service during the calendar month of September,would be on the order of ten days.
I informed'the licensee that I did not read the Technical Specification in a manner that would preclude thore> ugh annual inspections also required by the Technical Specifications.
'The subject was discussed with Walt Paulson, the RL Project Manager, on August 19, 1975 who concurs with the expressed position.
