Research Status and Prospect of Comprehensive Utilization of Nuclear Energy postprint

Abstract: Nuclear energy is essential for energy supply and national security. Compared with hydropower, optoelectronics, and wind power, as the clean energy replacing fossil fuels in the future, nuclear power takes great advantage in technology maturity, economical efficiency, as well as sustainability and natural environment flexibility. Come so far, except for a few reactors used for district heating and seawater desalination, nuclear energy is mainly used for power generation. With the development of technology, especially the gradually matured and applied fourth-generation nuclear energy system, nuclear energy is expected for a comprehensive utilization in different areas. This paper elaborates the current status and future development trend of nuclear energy utilization from the highefficient power generation, high-temperature steam electrolysis, water desalination, district heating, and high-temperature industry process. Finally, it is expected that in the near future nuclear energy will occupy an important position in the hybrid-energy system.
