- Ib October 26, 1979 Mr. James P. O'Reilly, Director Serial No. 863 Office of Inspection & Enforcement PSE&C/WLT:lga U.S. Nuclear Regulatory Comission Region II 101 Marietta Street, Suite 3100 Docket Nos. 50-404 Atlanta, Georgia 30303 50-405
Dear Mr. O'Reilly:
We have reviewed I.E. Bulletin 79-23 with regards to the Emergency Diesel Generators presently on order for North Anna Units 3 and 4. The equip-ment manufacturer, Colt Industries, has infomed us that the excitation power transfomer is to be connected to the generator leads utilizing a floating-wye primary winding configuration. Therefore, no circulating hamonic currents of the type discussed in I.E. Bulletin 79-23 can flow in this transfomer. Steps will be taken to insure that this transfomer primary winding is never grounded.
This is our final response to thi bulletin. Should you require further infomation on this matter, please, ontact thig office.
