How has the NRC research program supported fire barrier activities?
The NRC’s Office of Nuclear Regulatory Research (RES) has supported the agency’s fire barrier activities by testing electrical raceway fire barrier systems (ERFBSs). During 2005, RES sponsored confirmatory fire endurance testing at Omega Point Laboratories (OPL) of typical Hemyc 1-hour rated ERFBSs. Sixteen tests were performed on conduits, cable trays, junction boxes, airdrops, and supports protected with Hemyc 1-hour rated ERFBSs. RES has also witnessed several industry-sponsored tests of ERFBSs.
