Mr. Robert L. Baer, Chief Light Water Reactor Branch No. 2
Reference:
McGuire Nuclear Station Units 1 and 2 Docket Nos. 50-369, -370
Dear Mr. Denton:
As requested by your letter of February 12, 1980 which discussed deficiencies in the rod drop analysis for McGuire Nuclear Station, the following coc:mit-ment is made to enhance protection against dropped control rod events. These commitments may be modified pending Westinghouse's review of this subject.
In the manual mode of reactor control from 0 to 100% reactor power there will be no change in current McGuire operating procedures.
In automatic mode of reactor control from 0 to 90% reactor power there will be no change from current McGuire operating procedures.
In the automatic mode of reactor con-trol from greater than 90% reactor power control rod Bank D must be withdrawn greater than or equal to 215 steps. These restrictions will be incorporated into station operating procedures and Technical Specifications as appropriate.
Very truly yours,
/Q&'Q 0
