Smallest Light-Water Reactor

Small Modular Reactors (SMRs)

Our efforts to redefine nuclear technology and set new standards have not gone unnoticed. SMRs are attracting the attention of government officials, regulators, and energy leaders as a potential addition to the nation’s energy mix.


Because of their small size - less than 300 MWe, compared to a typical nuclear power plant of 1,000 MWe - SMRs have many useful applications, including generating emission-free electricity in remote locations where there is little to no access to the main power grid or providing process heat to industrial applications.

At up to 60 MWe (gross), the NuScale Power Module is the smallest of the light-water SMRs, broadening its market reach and application to markets that require smaller sizes and for customers who wish to make smaller investments in nuclear power.

NuScale’s small size and simple design eliminates many of the large and complex systems (e.g., pumps, motors, valves, piping) found in today’s nuclear power plants and other SMR designs. As a result, NuScale’s plant is safer, and less expensive to build and operate.

With the small design, our reactors fit more uses, spaces and budgets, yet it is big enough to meet expanding needs. Our goal is to create smarter, safer, cleaner and cost competitive energy that spans the globe and powers all humankind.
