Fire Protection Research Program Corner Effects Tests
Under the direction of the Nuclear Regulatory Commission, Sandia Laboratories has been conducting confirmatory research in fire protection for nuclear power plants. During all previous full scale fire tests at Sandia Laboratories involving fires, both electrically and exposure initiated, an open area in a nuclear power plant was simulated. The question was often asked, 'How much contribution to fire severity does a reradiating ceiling and wall make.' This report presents the results of several tests which address this question. By quantifying the effects of corner reradiation (i.e., a ceiling joining a wall) at different distances from a horizontal array of cable trays ignited by an exposure fire, it was found for the cables tested that fire damage, as measured by the extent of cable insulation degradation, varied approximately as the inverse of the square of the distance separating the cables from the corner. As experienced in previous Sandia fire tests, the difference in fire resistance between IEEE-383 qualified cable and unqualified cable was apparent in these corner-configuration tests.
