Simulation of JMCT based on JLAMT visualized modeling tool

The 3-D Monte Carlo transport code JMCT is developed by Software Center for High Performance Numerical Simulation independently and JLAMT is its pre-processing visualized modeling tool. Benchmarks including BW, KRITZ, BEAVRS et al were simulated by JMCT and MCNP5 codes, in addition, the effective multiplication factors and tally results were compared with the MCNP5 code and measured data separately. Effective multiplication factor calculations between two codes agree well with each other within 89.1 pcm for the KRITZ2 benchmark, the relative difference in power distribution between JMCT and MCNP5 is below 2% mostly, average difference is about 1%; as for BEAVRS benchmark, the maximum differences of the core radial power distribution of JMCT compared to MCNP5 and measurements are 7.06% and 16.6% respectively, JMCT control rod bank worth calculation results show good agreement of JMCT with MCNP5 and measurement.
