Abstract: A core simulation software for 3-D two-neutron energy groups is developed.This software is used to simulate the ship reactor with hexagonal fuel subassembly after 10、150 and 200 burnup days,considering the hydraulic and thermal feedback.It shows that this software is applicable in the real time simulation of nuclear reactor core physics.It accurately simulates the characteristics of the fast and thermal neutrons and the detailed power distribution in a reactor under normal and abnormal operation condition.
