摘要

This paper describes the calculation model of radiation source program cosSOURCE in COSINE code package for the fission products, activation products, corrosion products and tritium source term in the PWR primary coolant system. The code is able to perform the time-dependent and maximum fission products activities, as well as activation products activities at different locations in the primary circuit, corrosion products activities in the reactor coolant, and tritium activity in RCS during normal operation and refueling period of nuclear power plant. The relevant results shown in this paper indicate that both the computational model and the code implementation of cosSOURCE code for RCS source term analysis are reasonable. This paper only describes the calculation model of RCS source term, and carries out preliminary calculation. In the future study, the systematic test for all functions of the cosSOURCE will be conducted.
