i' NUMBER OF FAILURES IN NUMBER OF FAILURES IN LAST 20 VALIO TESTS

• LAST 100 VALID TESTS

• TEST FREQUENCY g1 <4 At least.once per 31 days

+ '

1 2** 15 At least once per 7 days

• 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 condition is completed, provided that the overhaul, including appro-priate 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 completion of 14 consecttive tests in a single series. Ten of these tests shall be in accordance with the routine Surveillance Requirements 4.8.1.1.2.a.4 and 4.8.1.1.2.a.5 and four tests in accordance with the'184 day te' sting requirement of Surveillance Requirements.4.8.1.1 2.a.4 and 4.8.1.1.2.a.5. If this criterion is not satis-fied 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 l e.- ,
