Abstract:

A major risk to a nuclear power plant is the possibility of serious fire. There is a need to know the heat release rate behavior of combustible fuels in the plant in order to help reduce the fire threat to these facilities. Heat release rate characteristics of cable tray fires and some of the associated potential external ignition sources are discussed. Existing correlations are given to determining the time to ignition and the subsequent heat release rate of spills and pools of flammable liquids. Approximate correlations are developed for heat release rate for trash fires as a function of fire size and for one particular cable tray array arrangement as a function of the type of cable. In addition, a scheme is given for calculating the heat release rate from wood fuel fires.
