Small Modular Reactors
Small modular reactors (SMRs) are nuclear fission reactors that are smaller than conventional reactors. The term “small” in the context of SMRs refers to design power output.
Small modular reactors have a power output of less than 300 MWe. The term “modular” in the context of SMRs refers to its scalability and to the ability to fabricate major components of the nuclear steam supply system (NSSS) in a factory environment and then transported them to the site.
The term “modular” in small modular reactors (SMRs) refers to the design concept where the reactor is built as a series of small, self-contained units that can be combined to form a larger power plant. The modular design of SMRs allows for greater flexibility in the construction and operation of the reactor.
The modular approach allows for standardized designs that can be replicated across multiple units, reducing the cost and time required for licensing, construction, and operation. Additionally, the modular design of SMRs allows for scalability, where additional modules can be added to increase the capacity of the power plant. This flexibility and scalability make SMRs well-suited for meeting the energy needs of small communities or for use in remote or isolated areas.
Modular SMRs can also be deployed more quickly and easily than large, traditional nuclear reactors, which require significant infrastructure and lead times for construction. The modular design can also help with maintenance and replacement, as individual modules can be taken offline and replaced without affecting the operation of the rest of the plant.
