Super Monte Carlo Simulation Program for Nuclear and Radiation Process (SuperMC) is a CAD based Monte Carlo program for integrated simulation of nuclear system by making use of hybrid MC and deterministic methods and advanced computer technologies, developed by FDS Team in China. The effective neutron multiplication factor keff is a key parameter for criticality calculation in safety design and analysis of reactors. In order to validate the correctness of criticality calculation of the latest version SuperMC 2.3, Handbook of International Evaluated Criticality Safety Benchmark Experiments (ICSBEP) was used for validation the code. Then 117 representative benchmarks from ICSBEP were selected as a validation suite which gave a broad coverage of fissile materials, reflector materials and energy spectrum for criticality safety applications. All the calculation results of SuperMC were compared with the experimental values and 78% of the results were within one or two σ of the experimental values. The average deviation between the results of SuperMC and MCNP was 7.034pcm by using the same nuclear data library. All the comparisons indicated that SuperMC2.3 worked correctly in the criticality safety calculations.
