Dear Mr. Seyfrit:

O

,4 South Texas Project Units 1 & 2 Docket Nos. STN 50-498, STN 50-499 First Interim Report Concerning Heating, Ventilation and Air Conditioning Design On May 8, 1981, pursuant to 10 C.F.R. 50.55(e), Houston Lighting and Power Company notified your office of a potentially reportable item concerning the consideration of certain faulted condition heat loads in the design of portions of the Heating, Ventilating and Air Conditioning (HVAC) system.

Based on our I

assessment of preliminary thermal environmental data, certain l

spaces and cubicles within the Mechanical-Electrical Auxiliary l

Building and the Fuel Handling Building might require additional HVAC capacity.

l A conceptual design for supplemental HVAC based on equip-ment design qualification temperatures and equipment heat losses l

for all modes of plant operation should be available by July 1, l

1981.

The design modifications will supplement the existing HVAC design.

Final HVAC design will be consis tent with equipment operability requirements under the most limit ing plant operating conditions.

Specific design modifications are dependent upon the results of our current evaluations.
