TRIMARAN: A Three Dimensional Multigroup P1 Monte Carlo Code for Criticality Studies

摘要

TRIMARAN is developed for safety analysis of nuclear components containing fissionable materials: shipping casks, storage and cooling pools, manufacture and reprocessing plants. It solves the transport equation by Monte Carlo method in general three dimensional geometry with multigroup P1 approximation. A special representation of cross sections and numbers has been developed in order to reduce considerably the computing cost and to allow this three dimensional code to compute with standard numerical program used in parametric studies. Some TRIMARAN results on critical experiments with PWR-type fuel pins in lightwater are presented in a tabular form. (ERA citation 10:002947)
