What is Small Modular Reactor?
The small modular reactor (SMR) is a nuclear reactor that produces electricity using a lower capacity compared to conventional nuclear power stations. The reactors utilize the modular assembly method, making it possible for reactors to be assembled at the construction site after being fabricated in factory facilities.
SMRs are distinct from conventional reactors driven by their smaller sizes, higher levels of safety, and scalability in the deployment process. They support the transition toward low-carbon energy by providing reliable baseload power, integrating with renewable energy systems.
