Dear Mr. Denton:

Our letter' Serial No. 641, dated November 21, 1978, which provided additional information for your review of settlement of the service water pumphouse for North Anna Units I and 2, indicated that additional Information would be provided concerning post construction movements of the circulati.ng water intake structure. Based on our review of the available data, we have concluded that the intake structure has not experienced either settlement or tilt, as evidenced by the agreement between construction specification eleva-tions for this structure and elevations actually measurent on the structure.

Ver truly you s,
