DPR-63 On August 18,
- 1981, licensee personnel discovered that both emergency diesel generators at Nine Mile Point Unit 1, Scriba, NY, were inoperable.
An NRC investigation into the circumstances surrounding this loss of operability was conducted at the facility on August 18-25 and September 1-3, 1981.
'As a
result of this investigation, and in accordance with the NRC Enforcement Policy, (47 FR 9987, March 9, 1982),
the followi'ng violations were identified:
A.
Technical Specification 3.6.3.e
- states, in part, "For all reactor operating conditions except startup and cold shutdown, the following limiting conditions shall be in effect:
(1)
One operable diesel-generator power system and one energized 115 KV external line shall be available.
If this condition is not met, normal orderly shutdown will be initiated within one hour and the reactor will be in the cold shutdown condition within ten hours...."
Contrary to the above, no operable diesel-generator power system was available during the period of reactor operation from August 16, 1981 to August 18,
- 1981, and no normal orderly shutdown was initiated or cold
-'sinai;t~"'iii <oq".ition >"nieved.

The limits...for significant process parameters should be identified.
The nature and frequency of thi s monitoring shall be covered by operating procedures, as appropriate."
