- POTEllTIAL DEFECTS IN BELOIT POWER SYSTEMS EMERGENCY GEt'ERATORS BACKGROUllD This circular addresses a potential deficiency involving the field leads of generators manufactured by Beloit Power Systems.
It is known that the subject generators have been couoled with Fairbanks Morse diesel engines for use in nuclear power facilities; however, it is not known whether they have been coupled with other diesel enoines for such use. Accordingly, the intent of this circular is to notify all nuclear power facilities of the potential 1
defect and to assure that appropriate remedial actions are taken, if needed.
The Nuclear Regulatory Commission was first informed of the potential defect by a phone call from Mr. R. H. Beadle of the Fairbanks Morse Engine Division of Colt Industries to Mr. D. W. Hayes of Region III on September 19, 1980. On September 20, 1980, a conference call was held between the NRC Duty Officer, personnel from Prairie Island Nuclear Power Station, Mr. Beadle of Fairbanks Morse and Mr. C. Evenson of Beloit Power Systems, the principal spokesman.
The purpose of this call was to describe an inspection method which Prairie Island personnel could use to examine the field lead assemblies of their cen-erators for the potential defect.
(i.'e have since been informed by the Resident Inspector that tha field lead assemblies of the Prairie Island generators did not have the susp e ted defects.)
In order to dissemiete this information on a timely basis, the NRC Duty Officer at Bethesda called those operating facilities which he knew were using the suspect generators on September 20 and 21,1980. The information conveyed included a description of the potential defect and a description of the aforementioned inspection method. The operating facilities called were:
