For fusion power generation, the reliable production of tritium, one of the fuels, is a critical challenge. The calculation of the tritium breeding ratio and the design of devices to optimize that ratio are essential when designing fusion demonstration reactor. Usually, MCNP codes are mainly used to calculate the tritium breeding ratio, but in this review, the feasibility of using Geant4, which is mainly used in the field of high-energy physics research, to examine tritium breeding ratio calculation was studied. Comparisons of tritium breeding ratios calculated using MCNP and Geant4 code in simple 1-D models with the same geometry and material properties showed agreement within a range of 1%. Comparisons of other variables (Flux, Energy Deposition) available from Monte Carlo computer simulations was also performed to consider the potential for expanding the utilization area of the Geant4 toolkit.
