Abstract: A particle transport code JMCT, which has independent intellectual property rights, is introduced. The code is developed on the JCOGIN infrastructure with multilayer modules. JMCT is capable to simulate the collision of particles with multi-group energy or continue energy. Two forms of parallelism are supported in JMCT, which are the domain decomposition and domain replication, with good scalability and communication capability. JMCT is equipped with a visualization CAD software which helps to model. The method for simulating the collision of particle with multi-group energy is described in detail. And calculation results of models are consistent with those obtained using the MCNP code. The speed of JMCT is three times faster than the MCNP code and the efficiency of parallelism can get up to 70% on 20 480 CPU cores in simulating 2109 particles.
