Simulation of the Physical Characteristic of the Westinghouse SMR Core Based on MCNP program

In order to investigate the features of small advanced reactors, the model of Westinghouse SMR core was established through the reference parameters in IAEA, VERA-PWR benchmark and AP1000 design control documents. The physical parameters of SMR core were calculated by MCNP program and the results were compared with the design value of AP1000. The results show that the core model was correct. The parameters of the model and the calculation results could be used for SMR design and related nuclear safety evaluation studies.
