Dear Mr. Keppler:

DOCKET NUMBER-50-483 CALLAWAY PLANT, UNIT 1 CENTRIFUGAL CHARGING PUMP INTERIM REPORT 80-2

References:

1. SLNRC 80-45, dated September 5, 1980
2. SLNRC 81-22, dated April 1, 1981 Reference 1 provided information on a potential deficiency involving operation of the centrifugal charging pumps following secondary side high energy line breaks. It was stated in reference 2 that design changes to correct the situation were still being evaluated by Bechtel, Westinghouse, and the SNUPPS utilities. At this time a final report is anticipated by November 1, 1982 pending completion of engineering and review of the design change.

Very truly yours, I Donald F. Schnell JGJ/jds cc: J. E. Konklin, Region III Richard DeYoung, Director I&E NRC Resident Inspector, Callaway Plant Missouri Public Service Commission 8209090090 820031 PDR ADOCK 05000483 S PDR SEP 7 E02 YNf
