Southern California Edison Company P. 0. BOX 800 2244 WALNUT GROVE AVENUE ROSEMEAD. CALIFORNIA 91770 June 17, 1983 Director, Office of Nuclear Reactor Regulation Attention: Mr. 0. M. Crutchfield, Chief Operating Reactors Branch No. 5 Division of Licensing U. S. Nuclear Regulatory Commission Washington, D.C. 20555 Gentlemen:
Subject:
Docket No. 50-206 SEP Topic XV-7, Reactor Coolant Pump Rotor Seizure and Reactor Coolant Pump Shaft Break Analyses San Onofre Nuclear Generating Station Unit 1
References:
A. Letter from D. M. Crutchfield, NRC, to R. Dietch, SCE, dated February 10, 1982 B. Letter from Walter Paulson, NRC, to R. Dietch, SCE, dated November 3, 1982 Reference A requested additional information on the subject analyses. Reference 8 provided the safety evaluation report on these analyses which concluded that sufficient information was not yet available to determine whether the consequences of these events were acceptable. Enclosed please find an evaluation of these transients.
Both the rotor seizure and shaft break transients have been analyzed, but only the most limiting results have been described in the enclosure. No fuel failures are predicted for these accidents and therefore no environmental consequences analysis is necessary.
Should you have any questions regarding these analyses or require additional information, please let me know.
Very truly yours, R. W. Krieger Supervising Engineer San Onofre Unit 1 Licensing Enclosure 8306240203 830617 PDR ADOCK 05000206 P
