During the operation of nuclear power plants, fuel fission and activation of boron and lithium in reactor coolant will produce a certain amount of tritium, which is difficult to be removed by conventional waste treatment system, and will cause certain harm to human body in the form of internal irradiation after entering the environment. In this paper, by analyzing the main sources of tritium production, the calculation model and key parameters of tritium production are evaluated, the tritium production and gas-liquid effluent source terms are obtained for HPR1000. The result shows that the activation of boron-10 in the reactor coolant is the main source of tritium production, accounting for about 66%, followed by the contribution of secondary source rods, accounting for about 30%. The gas and liquid effluents of tritium meets the requirements of GB6249-2011. The results can be used as a reference for environment impact assessment and determination of application value of tritium effluent.
