The computational procedure used in the WRAP-EM System to determine steady state operating conditions of a boiling water reactor (BWR) is described. WRAP-EM is a modular computational system developed at the Savannah River Laboratory in support of the Nuclear Regulatory Commission program of light water reactor safety analysis. WRAP-EM is capable of performing, automatically, the full scope of calculations required to audit evaluation model analyses of a loss-of-coolant accident (LOCA). This steady state computational procedure can be used to compute the equilibrium state of a BWR system corresponding to a particular system nodalization. With this procedure, BWR transient calculations can be performed without extensive manual calculations of the initial conditions.
