Dear Mr. Denton:

As re' quested by Mr. Walter Haas of your office during a phone conversation with Mr. Marvin Tower of Vepco on July 18, 1980, we are providing additional information concerning the Quality Assurance List for North Anna Unit 2.

For the Control Room Air Conditioning System, air makeup is provided by the vent fans. Therefore, no makeup fan motors exis't in this system. Ventilation for the Diesel Generator Building is provided 3

by the normal flow of intake air to the generators through louvers when operating. There are no separate supply fans or proportioning dampers.

Very truly yours, lhC f/"

'E.
