20555 Gentlemen:

VIRGINIA ELECTRIC AND POWER COMPANY NORTH ANNA POWER STATION UNITS NO. 1 AND 2 CORE UPRATING - REQUEST FOR ADDITIONAL INFORMATION Your letter of October 23, 1985 requested additional information regarding the proposed core uprate for North Anna Units No I and 2.

You also requested that we advise you of our schedule for providing this information should we be unable to provide our response within the 60 days requested by your letter.

Since our response will require additional safety analysis on the part of both our NSSS Vendor and Balance-of-Plant Architect-Engineer, we may be unable to meet the requested schedule.

However, we are making every effort to do so, and in no event will our response be delayed beyond February 15, 1986.

Very truly yours, 1
