THIRD INTERIM REPORT Description of Deficiency A potential defect exists when the governor lube oil cooler on a standby diesel generator is located above the maximum elevation of the piping between the coolers and the governor. If the oil level in the governor is low, air could be trapped in the Lube Oil System. The diesel generators were supplied by Delaval, Incorporated (Delaval), Oakland, California.
This deficiency was reported to NRC-0IE, Washington, DC, under 10 CFR 21 by TransAmerica Delaval letter dated December 9, 1981. The condition has been verified as a problem by Bellefonte field personnel. This deficiency does not apply to the Delaval supplied diesela at Hartsville and Phipps Bend Nuclear Plants.
Interim Progress Delaval has provided TVA with the procedure and drawing by which the governor lube oil cooler may be relocated below the governor. TVA is still working with the vendor to identify the cause of this deficiency and the associated action to prevent recurrence.
