摘　　要：分析了压水堆核电厂运行状态下气液态放射性流出物的产生和排放途径,建立了压水堆核电厂运行状态下气液态放射性流出物源项的计算模型,开发了具有良好人机界面的计算程序CPGale,并采用国内在役压水堆核电厂的流出物源项实测值对程序进行了验证。结果表明,基于CPGale程序计算所得流出物源项相比实测值具有适度的保守性,可满足工程设计的需求。Following the analysis on the generation and discharge mechanism of radioactive gaseous and liquid effluents during normal operation of pressurized water reactor nuclear power plant,the calculation model is improved and the calculation code CPGale with good man-machine interface is developed.The CPGale code is validated by operation data of in-service nuclear power plant in China.The validation result shows that the radioactive gaseous and liquid effluent source term calculated by CPGale code has an appropriate conservation compared with the operation data of in service nuclear power plant.The CPGale code can fulfill the requirements of nuclear power plant design and can be used in engineering applications.
