Dear Mr. Haynes:
POTENTIAL CONSTRUCTION DEFICIENCY EMERGENCY DIESEL GENERATORS -
"0" RINGS HOPE CREEK GENERATING STATION On December 13, 1982, a verbal report was made to Region I, Office of Inspection and Enforcement representative, Mr. L. Tripp, advising of a potentially significant construction deficiency concerning our Emergency Diesel Generators.
The following information is provided in accordance with the requirements of 10CFR50.55(e).
By letter dated October 6, 1982, Robertshaw Controls Company reported this problem to Colt Industries and the NRC in accord-ance with 10CFR21.
Colt Industries indicated to us that a potential problem exists with Robertshaw thermostatic valves used in the cooling system for diesel generators.
If the cooling water becomes contaminated with diesel fuel, an "0" ring in the valve poppet swells and may cause sluggish operation or jamming of the valve.
Bechtel Power Corporation is evaluating the safety implications of this condition postulating cooling water contamination by diesel fuel.
Determination of corrective action is pending receipt of detailed instructions from Colt Industries, the manufacturer of our diesel generators.
