Fire tests of wire and cable for DOE nuclear facilities
The Fire Research Discipline of the Hazards Control Department of Lawrence Livermore National Laboratory conducted a fire test program. Their primary concern was that the effects from fire would cause disruption of signals within cable trays resident in DOE nuclear facilities. Such malfunctions could adversely effect or prevent the safe shut down or other critical control functions. Four cable bundles comprised of a power cable, coaxial, and two multiconductor cables were laid in fully loaded 6-ft ladder type cable trays and energized with dc current. The power cable in each bundle was energized while the remaining cables in the bundle along with the cable tray were monitored for current transfer. Five full-scale fire tests of grouped cables in trays were conducted to address the potential occurrence of various types of electrical failures. The cable tray was supported above a test fire produced by a natural gas fired burner.
