$UBJECT: COMANCHE PEAK STEAN ELECTRIC STATION (CPSES), UNIT 1 DOCKET NO. 50-445 0UTAGE TINES AND SURVEILLANCE TEST INTERVALS FOR VARIOUS ENGINEERED SAFETY AND REACTOR TRIP FUNCTIONS LICENSING ANENDNENT REQUEST 91-003 Gentlemen:

Pursuant to 10CFR50.90, Texas Utilities Electric Company (TU Electric) hereby requests an amendment to its Facility Operating License No. HPF-87 by incorporating the enclosed change to Technical Specification Tables 3.3-1, 3.3-2, 4.3-2, and BASES 3/4.3.1 and 3/4.3.2 for Comanche Peak Steam Electric Station.

The enclosed License Amendment Request (LAR) proposes to modify the Comanche Peak Steam Electric Station Unit 1 Technical Specifications by changing the Allowed Outage Times (A0T) and the Surveillance Test Intervals (STI) for Analog Channels shared by both the Reactor Trip System (RTS) and the Engineered Safety Features Actuation System (ESFAS).

The proposed change will result in less frequent testing which will result in fewer inadvertent reactor trips and fewer actuations of ESFAS components.

The change proposed in this LAR is not required to address an imediate safety concern. TU Electric desires to implement the Nquested change as soon as possible and therefore, requests timely review and approval of this LAR by the NRC. TU Electric requests that the revised Technical Specifications be made effective seven days after approval of the license amendment by the NRC.
