FOLLOW-UP RE VEST FOR ADDITIONAL INFORMATION REGARDING GENERIC LETTER 92-08 "THERMO-LAG 330-1 FIRE ARRIERS" SUS UEHANNA STEAM EL C

A IO UNITS D 2 DOCKET NOS. 50-387 AND 50-388
1.0 BACKGROUND
By letter dated August 2,
- 1995, Pennsylvania Power and Light Company (the licensee) submitted a response to the staff's Request for Additional Information (RAI) dated June 13, 1995, related to Generic Letter (GL) 92-08, "Thermo-Lag 330-1 Fire Barriers," for Susquehanna Steam Electric Station (SSES),
Units 1 and 2.
The licensee stated that a preliminary evaluation of ampacity derating for Thermo-Lag-enclosed raceways installed at SSES indicated that for all cases except 3-hour fi're rated conduits on Unit 2, the allowable derating is greater than the factors derated from the Texas Utilities Electric Company's (TUEC) tested configurations.
- Further, the licensee stated that destructive examinations and detailed field walkdowns would be utilized to confirm that the SSES installed Thermo-Lag configurations are representative of the TUEC-tested configurations.
The staff has completed the review of the licensee's submittal and requires that the following questions be addressed by the licensee.
2.0 QUESTIONS
- 2. 1 In your submittal dated August 2,
- 1995, you did not specify a derating value for the 3-hour fire rated conduit configurations since TUEC did not include any of the subject barriers in their test program.
Florida Power Corporation has recently completed ampacity derating tests of 3-hour Thermo-Lag-enclosed conduit configurations.
These tests were conducted in accordance with the Institute of Electrical and Electronic Engineers (IEEE) Standard P848, Draft 16, "IEEE Standard Procedure for the Determination of the Ampacity Derating of Fire-Protected Cables," at the Underwriters Laboratories Northbrook Testing Station in Northbrook, Illinois. -Given this new test data for 3-hour fire rated conduit configurations please describe how you have incorporated this information and what are the ampacity derating factors now being utilized for the 3-hour Thermo-Lag fire barriers in the SSES electrical design calculations.
2.2 Describe whether the results of your destructive examinations and detailed field walkdowns to date demonstrate that all of the installed configurations are representative with the TUEC-tested configurations.
In the event of any deviations with the TUEC-tested configurations, the licensee is requested to ascertai'n their impact on previous ampacity derating determinations.
