For the purposes of determining t.he 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-1 priate post-maintenance operation and testing, is specifically approved by the manufacturer and if acceptable reliability has been demonstreted.

tests in accordance with the 184-day testing requirement of Surveillance Requirement 4.8.1.1.2.f.

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.

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