SUS(UEHANNA STEAM ELECTRIC STATION UNITS 1&2 DOCKET NOS. 50-387, 50-388 FOLLOWUP TO REQUEST FOR ADDITIONAL INFORMATION REGARDING GENERIC LETTER 92-08 "THERMO-LAG FIRE BARRIERS" September 23,

1994, Request for Additional Information The RAI dated September 23,

1994, requested information regarding important barrier parameters, Thermo-Lag barriers outside the scope of the NEI, program, ampacity derating~

and schedules.

In the licensee's response dated December 22, 1994,. a schedule for the completion of corrective actions necessary for the resolution of the Thermo-Lag issue was not provided.

A schedule for completion of all corrective actions is requested.

During the public meeting held on March 14, 1995, with the licensees for the four lead plants for the resolution of Thermo-Lag issues, the staff responded to the question "Will the resolution of the ampacity derating concern be deferred until agreement is reached on the appropriate testing protocol(i.e.,

IEEE P848)?"

The staff reiterated the position which was previously stated in the September 1994 RAI, that the ampacity derating concern could be resolved independently of the fire endurance concerns.

At this time the staff is not

'aware of any NEI initiative to address the ampacity derating issue.

After a review of.the tests which were performed under the draft IEEE standard

P848, the staff transmitted comments which were designed to ensure the repeatability of test results to the IEEE Working group responsible for the test procedure.

The licensee 'is requested to submit it's ampacity derating evaluations, including any applicable test reports in order to provide an adequate response to. Generic Letter 92-08 reporting requirement 2.(c).
