4.
Nature of the deficiency... and the safety hazard which... could be created by such a deficiency...:
A.
Description of the Deficiency The elevation of the governor lube oil cooler on the Transamerica Delaval Standby Diesel Generators is above the oil level of the governor.
This presents the possibility of air being trapped in the governor lube oil system when the oil level in the governor is low.
If air is trapped, engine starting.may be affected.
B.
Analysis of Safety Implications i
This deficiency, had it remained uncorrected, could have had an adverse af fect on the safety of plant operations.- If the diesels were required to provide AC power to the Division 1 and 2 ESF Bus, during a LOCA condition or loss of offsite power, the air that may i
be trapped may affect engine starting and operation. Therefore, the diesels would be prevented from performing their design function.
