• A diesel generator shall be considered to be inoperable from the time of failure until it satisfies the requiremente of Surveillance Requirements {

7 4.8.1.1.2a.4 and 4.8.1.1.2a.5,

• • This test is required to be completed regardless of when the inoperable diesel f$ generator is restored to OPERABILITY. The provisions of Specification 3.0.2 are not applicable, i

• Criteria for determining number of failures and number of valid tests shall be in accordance with Regulatory Position C.2.e of Regulatory Guide 1.108, but determined on a per diesel generator basis.

• For the purposes of determining the required test frequency, the previous test failure count may be reduced to zero if a complete diesel overhaul to like-new conditions is completed, pro'vided that the overhaul including appropriate post-maintenance operation and testing, is specifically approved by the manufacturer and if acceptable reliability has been demonstrated. The reliability criterion shall be the successful conpletion of 14 consecutive tests in a single series.

during the first series of tests, any alternate criterion to be used to transvalue the failure count to zero requires NRC approval. -

• • The associated test frequency shall be maintained until seven consecutive failure free demands have been performed and the number of failures in the last 20 valid demands has been reduced to one.
