To ensure safety of fusion facilities, it is important to develop evaluation methods for tritium transfer in the environment. For estimation of tritium transfer in the terrestrial environment, we had developed a simple compartment model using the Migration Of GRound Additions (MOGRA) code. The model was composed by an air-soil-plant system. The target source terms were HT and HTO in the air. In addition, wet deposition was modeled by input of HTO to the system by rainfall. Tritium in the plant was divided into free water tritium (FWT) and organically bound tritium (OBT). The tritium concentration in the environmental medium was trial calculated for chronic and accidental HTO releases to the atmosphere, as preliminary calculation run of the model.
