Benchmark experiment and analysis of JMCT on nuclear critical safety

JMCT developed by Institute of Applied Physics and Computational Mathematics is a transport code based on Monte Carlo method. A series of benchmark experiments picked up from the international nuclear critical experiment database, were used to validate JMCT. The validation includes common fission nuclides(such as U and Pu), from lower enrichment to higher enrichment, their thermal neutron groups and fast neutron groups, and common neutron poison and reflector. The results of JMCT were compared with the results of experiments by MCNP and MONK. The correctness of JMCT is preliminarily verified.
