Mr. James G. Keppler Regional Administrator U.S.'I4uclear Regulatory Commission Region III 799 Roosevelt Road Glen Ellyn, IL 60137 ULNRC- 717
Dear Mr. Keppler:
INTERIM 10CFR50.55 (e)/21 REPORT NO. U-66 CALLAWAY PLANT UNIT 1 On November 23, 1983, Union Electric reported a 10CFR50.55 (e)/21 deficiency to Paul Pelke, NRC Region III. The deficiency involves the failure of contactor coils in ITE Gould Motor Control Center two-speed starters for Containment Cooling Fan Motors.
The failure involves the slow speed 42S coils, four of which have failed (shorted) after operating for a period between thirty minutes and one hour of service. Special efforts were made to assure these coil failures were not caused by the mechanical interlock failure reported in Report No. U-65.
Union Electric has requested Bechtel to provide infor-mation on the failure and to determine if a generic problem exists with the contactor coil. ITE Gould will be contacted to provide information pertinent to the failure. A final report on this issue is expected to be submitted within 90 days of the date of this letter.
Very truly yours, l/ b?
