Description

A FORTRAN computer program named as STEADY-ACE has been developed to predict the three-dimensional distributions of neutron flux, power and void fraction in a BWR core. The program consists of two subprograms, i.e., the few-group three-dimensional diffusion subprogram DIFFUSION-ACE and the thermal-hydraulic subprogram HYDRO-ACE. The two subprograms are combined in an iterative way so that the interdependency of the power distribution and the void fraction distribution can be treated consistently. The program STEADY-ACE provides a prediction of BWR core performance in a good accuracy in a reasonably short computation time. The computation time of the example case of JPDR quarter core (72/4 assemblies) is 7 CPU minutes on the machine FACOM 230-75. (author)
