Dear Mr. Nichols:
SUBJECT:
Q-LIST REVIEW FOR VIRGIL C. SUMMER NUCLEAR STATION, UNIT 1 The Quality Assurance Branch has completed its review of Chapter 3 of the FSAR for the Virgil C. Summer Nuclear Station, Unit No.1, which identifies the structures, systems, and components subject to your Operational Quality Assurance Program.
Under a revised procedure that involves other NRR technical review branches in this review, we have identified certain deficiencies and have generated the enclosed request far additional information.
Your response to the enclosed request should be provided not later than February 13, 1981.
Please contact the staff's assigned project manager if you require any clarification of these matters.
Sincerely.
