Research on the impact of extreme climate change on the development of nuclear power technology in china

The increasingly severe climate conditions are not only bringing harmful effects on human survival and development, but also causing serious challenges to the safety application of nuclear power technology. There have been many operation incidents where extreme climate hazards affected the safe and stable operation of nuclear power plants (NPPs) worldwide. Humanity is entering an unknown territory of global climate damage, with the frequent occurrence of extreme climate disasters caused by greenhouse gas emissions, the impact of extreme climate hazards on the development of nuclear power technology application will become increasingly prominent. Based on the national energy development strategies and the relevant technical policies for nuclear power technology application, combined with the current development status of the commercial NPPs in China, an analysis was made on the interdependent relationship between extreme climate change and nuclear power technology development. On the analysis of the requirements of the national nuclear safety regulations, guidelines and standards, this paper analyzed the potential impacts of the external hazards caused by extreme climate change on the safe and stable operation of NPPs, discussed the current status of the protection design and the protection capabilities of the operating and constructing NPPs against extreme climate hazards in China. On this basis, this paper analyzed the future development directions of the protection against extreme climate hazards for nuclear power technology application in China, so as to effectively adapt to the possible impacts of the future extreme climate change on the safety application of nuclear power technology.
