Box 289 Wadsworth, Texas 77483 April 14, 1997 ST-HL-AE-5589 File No.: G26 10CFR50.73 STI: 30193215 U. S. Nuclear Regulatory Commission Attention: Document Control Desk Washington, DC 20555 South Texas Project Unit 1 Docket No. STN 50-498 Revision 1 to Licensee Event Report 94-019 Failure to Fully Meet the Requirements of Technical Specifications For Time Response Testing of the Reactor Containment Fan Cooler, and the Control Room Envelope Heating. Ventilation and Air Conditioning Systems Pursuant to 10CFR50.73, South Texas Project submits the attached revision to Unit i Licensee Event Report 94-019 regarding a failure to fully meet the requirements of Technical Specifications for time response testing of the Reactor Containment Fan Cooler, and the Control Room Envelope Heating, Ventilation and Air Conditioning Systems. This event did not have an adverse effect on the health and safety of the public.

This revision removes the commitment to revise the Safety Injection Actuation and Response Time Test surveillance procedure to include spin-up time for the Fuel Handling Building Heating, Ventilation and Air Conditioning system. A comprehensive review of the accident calculations for the Fuel Handling Building Heating, Ventilation and Air Conditioning system determined the only time response for meeting the accident analysis is the ventilation system bypass dampers shutting within a specified time after a radiological release reaches the sample point inlet. Changes are indicated by revision bars.

If you should have any questions on this matter, please contact Mr. S. M. Head at
