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.
