Criteria for determining the number of failures and number of' valid tests shall 1

be in accordance with Regulatory Position C.2.e of Regulatory Guide 1.108, Revision 1, August, 1977, but determined on a per diesel generator basis, j

For the purpose of determining the required test frequency, the previous i-test failure count may be reduced to zero if a complate' diesel overhaul to i

like-new condition is completed, provided that the overhaul, including-l appropriate post-maintenance operation-and testing, is specifically_ approved i.

by the manufacturer and if acceptable reliability has been demonstratedi Tne reliability criterion shall be the successful completion of 14 consecutive i

tests in a single series in accordance with the routine Survillance Require-1 ments of 4.8.1.1.2.a.5 and 4.8.1.1.2.a 6.

If this criterion is not satisfied i

during the first series of tests, any alternate criterion to:be used to j

transvalue the failure count to zero requires NRC approval.

- This test frequency shall be maintained until seven consecutive failure-free 2

demands have been performed and the number of failures in the last 20 valid I

demands has been reduced to one or less.
