SUBJECT:
UL FJRE TEST o
On September 15, 1978, a fire test of a full-scale vertical cable tray
.I array with cable protected by fire barriers and sprinklers was conducted at the Underwriters' Laboratory near Chicago, Illinois.
It was part of the NRC expeCited fire protection research program requested in the Commission's Order of April 13, 1978.
lhe purpose of the test was to demonstrate the effectiveness of area sprinklers and mineral wool blanket type cable tray fire barriers in preventing damage to cables as a result of an exposure tire created by igniting two gallons of heptane.
The Cemmissioners have i:een informed by the enclosed separate memorandum.
It is appropriate that the ACRS and Boards also be notified where this issue is relevant. We will continue our evaluation of the test resuits and considerations of new additional tests to be cor. ducted.
