Small nuclear power reactors - World Nuclear Association

Small Nuclear Power Reactors. (Updated June 2021) There is strong interest in small and simpler units for generating electricity from nuclear power, and for process heat. This interest in small and medium nuclear power reactors is driven both by a desire to reduce the impact of capital costs and to provide power away from large grid systems.

Nuclear Power Reactors - World Nuclear Association

Nuclear Power Reactors. (Updated July 2021) Most nuclear electricity is generated using just two kinds of reactor which were developed in the 1950s and improved since. The first generation of these reactors have all been retired, and most of those operating are second-generation. New designs are coming forward, both large and small.
