The test was classified as non valid in accordance with Regulatory Guide 1.108 in that the Diesel Start was terminated intentionally without loading.

'D' Diesel Generator Breaker Failed to Open Following P200 " Unit 2 Cold Functional" testing, breaker 1A20404 failed to open causing the 'D' Diesel Generator to be connected to the 4KV bus while it was energized by the off site power source. The breaker had to be opened locally and racked out in order to secure the diesel. Investigation revealed that the breaker's failure was attributed to a contact in the truck operated cell (TOC) switch which remained open with the breaker racked into the operate position. The 1A20404 TOC switch contacts were re-aligned such that the con-tacts close when the breaker is fully racked in. All other Unit 1 4KV breakers were inspected; no similar mis-alignments were found. Both the 'D' Diesel and its generator were inspected for damage. The 'D' Diesel Generator was run loaded and proper operation was verified approximately six hours following the event.

The test was classified as non-valid in accordance with Regulatory Guide 1.108.

'C' Diesel Generator Trip on Over-Excitation Durig the performance of surveillance testing , Diesel Generator 'C' tripped due to a generator over excitation alarm / trip. The cause of the trip was determined to be related to Startup Transformer Tap changes that increased plant voltage during the test. A followup diesel surveillance test was con-ducted after the trip; the test was classified as non-valid in accordance with Regulatory Guide 1.108, Section c.2.e. (2) in that the trip was caused by a condition bypassed durig emergency operation. The diesel was returned to service in two and a half hours following the trip.

'C' DieselTurboCharger Thrust Bearing Failure During the performance of Surveillance test procedure S0-224-002 " Eighteen Month Diesel Generator Auto Start and ESS Bus Energization on Loss of Off-site Power-Plant Shutdown", Diesel Generator 'C' tripped due to a turbo charger thrust bearing trouble alarm / trip. The cause of the trip was determined I to be excessive wear on the turbo charger thrust bearing that may be attri- l butable to a low turbo charger inlet pressure. Investigations are continuing to determine the cause of the low inlet pressure. The. thrust bearing was replaced and the 'C' Deisel returned to service in approximately sixty-eight hours.

The test was classified as non-valid in accordance with Regulatory Guide 1.108, Section c.2.e(2) in that the trip was caused by a condition bypassed during mergency operation.
