Abstract

A fast and self-consistent approach, PRELIM approach, is described in this paper with the aim of quickly delivering a multi-cycle equilibrium configuration using Monte Carlo models. This approach is based on simple reactor physics, and is easily incorporated into standard Monte Carlo core design tools. The primary purpose of this study is to provide an efficient approach to enable routine calculations for feasibility studies of nuclear reactor design concepts based on Monte Carlo methods. The approach is capable of realistic conceptual core design calculations in a repeated manner with sufficient accuracy of key performance parameters. The validity of the PRELIM approach is demonstrated by benchmarking its results to solutions provided by a higher order approach with detailed core calculations in a given example problem.
