Dear Dr. Murley:

POTENTIAL CONSTRUCTION DEFICIENCY OUESTIONABLE D/G RESISTORS HOPE CREEK GENERATING STATION On September 1, 1983, a verbal report was made to Region I, Office of Inspection and Enforcement representative Mr. E. C. McCabe, advising of a potentially significant construction deficiency concerning resistors installed in our Emergency Diesel Generators. The following interim report is provided in accordance with the requirements of 10CPR50.55(e).

On August 19, 1983, Basler Electric Company of Highland, Illinois, reported to the Nuclear Regulatory Commission, via 10CFR21, a problem with four-Watt 4,000 ohm resistors used in safety-related systems. On the Hope Creek Project this resistor is used in the exciter section of our Emergency Diesel Generators. The supplier reports high-temperature failure of these resistors. Basler Electric is a sub-supplier of Colt Industries, the manufacturer of our Emergency Diesel Generators.

Bechtel Power Corporation, our Architect / Engineer and Constructor, has requested Colt Industries to provide all necessary information for the requisita safety analysis and to define the remedial actions to be taken, as applicable.
