- e TABLE 4.8.1.1.2-1 DIESEL GENERATOR TEST SCHEDULE NUMBER OF FAILURES IN NUMBER OF FAILURES IN LAST 20 VALID TESTS
- LAST 100 VALID TESTS
- TEST FRE0VENCY s1 s4 At least once per 31 days 22 25 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, except that the valid test failures of the Division 1 diesel generator identified on August 3,1993;-
June 7, 1994; and July 12, 1994 may be excluded from.the total number of failures used to determine the diesel generator test frequency.
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 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 completion of 14 consecutive 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.n.5 and four tests in accordance with the 184-day testing.
requirement of Surveillance Requirements 4.8.1.1.2.a.4 and 4.8.1.1.2.a.5.
If this criterion is not satisfied.during the first series.of tests, any alternate criterion to be used to transvalue the failure count to"zero requires NRC approval.
- This 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 less than or equal to one.
