Dear Sir:
Three Mile Island Nuclear Station, Unit 1 (TMI-1)
Operating License No. DPR-50 Docket No. 50-289 Fire Proof Cable Development and Test Program
Reference:
NRC Letter, from J. Van Vliet to GPU Nuclear Corporation "GPU Nuclear /Rockbestos Fire Proof Cable Development and Test Program" Dated August 24, 1983.
As a result of a meeting with the NRC on August 5, 1983, (reference 1), we have revised the Cable Development and Test Program to incorporate the staff's concerns and tailor the program with ASTM-E119 (Standard Methods for Fire Tests of Building Construction and Materials) and plant specific require-ments.
Enclosed is a draf t copy cf " Fire Proof Cable Development and Test Program" for your review and comments.
This draft resolves all the questions raised by the staff during the August 5th meeting and also provides the preliminary cable configuration for the oven test.
The program details the test parameters and the bounding condi-tions for the cable for specific usage.
Appendix - A to this report draws a parallel between ASTM-E-119-82 Fire Test and the proposed GPUN/Rockbestos Cable Fire Test.
GPUN intends to use this cable in lieu of the proposed 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> fire barrier in a location where:
l a) Fire detection and suppression system protects that location, or b) where damaged redundant cable can be replaced within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.
