Market Definition
According to the World Nuclear Association, “Small modular reactors (SMRs) are defined as nuclear reactors generally 300 MWe equivalent or less, designed with modular technology using module factory fabrication, pursuing economies of series production and short construction times.” SMRs vary in terms of size and thermal output. These reactors can be used for various applications, such as power generation, process heating, desalination, and industrial uses. Their designs may employ light water as a coolant or other coolants, such as gases, liquid metals, or molten salts. Small modular reactors offer multiple benefits, such as small physical footprints, reduced capital investments compared with traditional nuclear power plants, the ability to be sited in locations not possible for larger nuclear plants, and provisions for incremental power additions.
The small modular reactors market size is defined as the sum revenue generated by global companies' manufacturing small modular reactors.
