Frontiers and review in global nuclear energy science and technology
This paper summarizes the recent progress of global nuclear energy science and technology,focusing on nuclear fission and fusion,coupling utilization of nuclear energy and other energies,frontier technology of nuclear energy informatization and nuclear waste treatment.The global research and development of nuclear energy is developing steadily.Nuclear power technology will gradually realize the development from the second generation to the third generation.Small reactors have good applications in the sea,land and air.The progress of nuclear fusion technology has been introduced,including high temperature superconducting fusion,laser ignition inertial confinement fusion,Tokamak fusion device,International Thermonuclear Experimental Reactor and Chinese Fusion Engineering Testing Reactor.The coupling utilization of nuclear energy and other energies such as hydrogen energy and solar energy,provides a new solution for the development of renewable energies and the realization of carbon peaking and carbon neutrality goals.High-precision multi-physical field coupling analysis and calculation,digital twin technology,informatization and database construction are important directions for sustainable development of nuclear energy in the future.The latest advances in radioactive waste treatment and disposal technologies have been summarized,including the reduction and solidification of low-and medium-level radioactive waste,radionuclide removal and vitrification of high-level radioactive waste,and treatment and disposal of spent fuel.The overall situation shows that nuclear energy is still an important part of the global energy structure.
