• February 17, 1983 Docket Nos. 50-327/328 Mr. S. A. Whit'e Manager of Nuclear Power l Tennessee Valley Authority 6N 32A Lookout Place 1101 Market Street Chattanooga, Tennessee 37402-2801

SUBJECT:

CONTROL ROOM EMERGENCY VENTILATION SYSTEM (TAC 00254,00255)

(TS 87-47)

Re: Sequoyah Nuclear Plant, Units 1 and 2 The Commission has issued the enclosed Amendment No. 68 to Facility Operating License No. C?R-77 and Amendment No. 60 to Facility Operating License No.

DPP-79 for the Sequoyah Nuclear Plant, Units I and 2, respectively. These amendments are in response to your application dated January 11, 1987 which proposed revising Technical Specification (TS) survedlance recuirements (SR) 4.7.7.e.3 (Units 1 and 2) to allow up to 1000 cubic 'eet per minute (cfm) inteke of fresh air during operation of the control ecom emergency ventiletion system (CREVS). The previous requirement allowed only up to 200 cfm.

This request was made on an emergency basis because of a potential for impacting the Unit 2 heatup. Since your application, it has been detemined that this change to the TS does rot impact Unit 2 heatup. Therefore, the NRC staff has detemined there is not a basis for such action.

The staff has completed its evaluation of your request. Based on the enclosed Safety Evaluation, the staff has fcund the proposed changes to be acceptable.
