Abstract:

In order to further improve the national nuclear material supervision system, consolidate the foundation for the development of China's nuclear security cause and provide an effective Chinese nuclear security plan for the international community to prevent nuclear terrorism and international cooperation in the nuclear energy field in the "the Belt and Road", in-depth research and practical exploration on nuclear security related theories were carried out. Based on the analysis of the essential goals and core concerns of nuclear security, we proposed the establishment of a framework for nuclear security defense lines at the national and nuclear facility levels, and specified the content of the framework. The results show that the national nuclear security work should ensure nuclear materials within the scope of national regulation throughout their entire lifecycle are under controlled and protected conditions. At the national level, nuclear security work should strengthen the safety supervision of nuclear materials nationwide from three stages of control: source, process, and consequences. The nuclear security work at the level of nuclear facilities is a specific control measure at the implementation level of national nuclear material safety supervision, and its core purpose should be to prevent the threat of nuclear terrorism.
