Numerous supplements by TU Electric and follow-up requests for additional information by the -

U.S. Nuclear Regulatory Commission (NRC) staff were issued in regard to Thermo-Lag 330-1 l fire barriers installed at CPSES, Unit 1.

The NRC staff has reviewed your letters. Your responses dated April 9 and May 1,1998,  !

stated that you would perform fire endurance tests and undertake upgrades to Thermo-Lag I installations (Thermo-Lag 330-1 fire barrier corrective actions). The NRC staff issued a Confirmatory Order Modi'ying License on July 28,1998, confirming TU Electric's commitment to {

i complete implementation of Thermo-Lag 330-1 fire barrier corrective actions by December 31, j 1998. By letter dated December 22,1998, you stated that all corrective actions for the l resolution of the Thermo-Lag issues had been implemented at CPSES, Unit 1.

The i staff's review is documented in the enclosed Supplemental SE. On the basia of its review, the l

staff has determined that you have provided the information and performed the actions I requested in GL 92-08 and the actions tracked by TAC No. M85536 are complete. This j completes the staff's evaluation related to the qualification of the Thermo-Lag fire barriers at  !
