UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D. C. 20555 November 22, 1988 Docket No.:
50-206 Mr. Kenneth P. Baskin Vice President Southern California Edison Company 2244 Walnut Grove Avenue Post Office Box 800 Rosemead, California 91770
Dear Mr. Baskin:
SUBJECT:
RECERTIFICATION OF CHARGING PUMP MOTOR RATING (TAC NO. 69585)
Re:
San Onofre Nuclear Generating Station, Unit No. 1 By letter dated September 22, 1988, you responded to License Condition 3.L(6) which required recertification of the charging pump motors to at least 700 horsepower or rewinding or replacement. Your letter stated that "Based on a Westinghouse evaluation, the motors have been recertified to 700 horsepower with a service factor of 1.15. Recertification of the motors in accordance with the license condition has been accomplished."
This submittal is not sufficient to allow the NRC staff to complete its review of the recertification of the motors because the basis for the conclusion was not provided.
Your letter also states that one of the motors may have been rewound in 1972 and this is unresolved at this time.
To complete our review of this matter, you are requested to:
- 1. Submit to NRC for review the evaluation and formal certification indicating the new rating prepared by Westinghouse Electric Corporation (the manufacturer). This submittal should be at least similar to the evaluation of the motors submitted by SCE letter of July 21, 1988.
- 2. Resolve the question about whether or not one motor was rewound and provide detailed information to substantiate your conclusion that both motors are "capable of performing their intended service operation,"
including environmental qualification.

- 3. Provide your schedule for providing a full response to License Condition 3.L(5) regarding confirmatory load tests of the major loads on the diesel generators (including the charging pumps).
Please contact us should you have any questions regarding these matters. Your response is requested within thirty days of your receipt of this letter, Sincerely, Charles M. Trammell, Senior Project Manager Project Directorate V Division of Reactor Projects -
