MEMORANDUM FOR:
Domenic B. Vassallo, Assistant Director for Light Water Reactors, DPM FROM:
Robert L. Tedesco, Assistant Director for Plant Systems, DSS
SUBJECT:
UL FIRE TEST On September 15, 1978, a fire test of a full-scale vertical cable tray array with cable protected by fire barriers and sprinklers was conducted at the Underwriters' Laboratory near Chicago, Illinois.
It was part of the NRC-expedited fire protection research program requested in the Commission's Order of April 13, 1978.
Ihe purpose of the test was to demonstrate the effectiveness of area sprinklers and mineral wool blanket type cable tray fire barriers in preventing damt.a to cables as a result of an exposure tire created by igniting two callons of heptane.
The Commissiorers have been informed by the enclosed separate memorandum.
It is appropriate that the ACRS and Boards also be notified where this issue is relevent. We will continue our evaluation of the test results and considerations cf new additional tests to be r;nducted.
