通过对压水堆主回路中裂变产物的生成、释放和迁移等过程进行研究,建立了各过程的计算模型,形成了一套完整的模块化的压水堆主回路裂变产物源项计算方法。通过对主回路中的材料腐蚀、辐照活化、核素迁移以及沉淀等过程进行研究,建立了模块化的腐蚀产物源项计算模型,形成了一套完整的压水堆主回路腐蚀产物源项的计算方法。在此基础上开发了拥有自主知识产权的压
Through the research on the process of generation, release and migration of fission products in the main circuit of PWR, a calculation model of each process is established, and a complete modular calculation method of the source term of fission products of PWR main loop is formed. Through the research on the material corrosion, radiation activation, radionuclide migration and precipitation in the main circuit, a modular calculation model of the source term of corrosion products was established and a complete set of source items of the main circuit corrosion products of PWR The calculation method. On this basis, developed with independent intellectual property pressure
