NuScale Power

Company developing modular and scalable small nuclear power systems.

NuScale Power, LLC is a leader in small modular reactor (SMR) innovation. NuScales modular light water reactor aims to supply reliable and abundant carbon-free nuclear energy. It features a fully fabricated NuScale Power Module™ capable of generating 60 MW of electricity using a safer, smaller, scalable version of pressurized water reactor technology. A NuScale power plant houses up to 12 SMRs for a total facility output of up to 720 megawatts.

NuScale has spent more than $800 million on its design—$288 million from the Department of Energy (DOE) and the rest mainly from NuScale's backer, the global engineering and construction firm Fluor. The design is now working its way through licensing with the Nuclear Regulatory Commission (NRC), and the company has lined up a first customer, a utility association that wants to start construction on a plant in Idaho in 2023.


NuScale Power, LLC was officially incorporated in 2007 by founders Jose N. Reyes (CTO) and Paul G. Lorenzini (Former CEO). However, the development of the original reactor concept began in 2000 as a collaborative project between Oregon State University (OSU), the Idaho National Engineering and Environmental Laboratory, and Nexant. The original concept, the “Multi-Application Small Light-Water Reactor” (MASLWR), was refined by OSU and upon conclusion of the 3-year project became the basis for the NuScale design.


Since October 2011 Fluor Corporation has been NuScale’s majority investor and a key strategic partner for the engineering, procurement and construction services. Several other key strategic partners also providing investment are:

  • Oregon State University (OSU)
  • ARES Corporation
  • Enercon Services (ENERCON)
  • Ultra Electronics
  • Doosan Heavy Industries and Construction Co., Ltd. (DHIC)
  • Sargent & Lundy

Mini nuclear plants are almost here. Is the U.S. ready?

BOISE, Idaho (AP) - U.S. officials have for the first time approved a design for a small commercial nuclear reactor, and a Utah energy cooperative wants to build 12 of them in Idaho. The U.S. Nuclear Regulatory Commission on Friday approved Portland-based NuScale Power's application for the small modular reactor that Utah Associated Municipal Power Systems plans to build at a U.S. Department of Energy site in eastern Idaho. The small reactors can produce about 60 megawatts of energy, or enough to power more than 50,000 homes. The proposed project includes 12 small modular reactors. The first would be built in 2029, with the rest in 2030. NuScale says the reactors have advanced safety features, including self-cooling and automatic shutdown. "This is a significant milestone not only for NuScale, but also for the entire U.S. nuclear sector and the other advanced nuclear technologies that will follow," said NuScale Chairman and Chief Executive Officer John Hopkins in a statement. Utah Associated Municipal Power Systems already has agreements with the Energy Department to build the reactors at the federal agency's 890-square-mile (2,300-square-kilometer) site that includes the Idaho National Laboratory, a nuclear research facility that would help with the development of the reactors. The Department of Energy has spent more than $400 million since 2014 to hasten the development of the small modular reactors, or SMRs. "DOE is proud to support the licensing and development of NuScale's Power Module and other SMR technologies that have the potential to bring clean and reliable power to areas never thought possible by nuclear reactors in the U.S., and soon the world," said Rita Baranwal, assistant secretary for Nuclear Energy. The energy cooperative has embarked...

A new generation of reactors will start producing power in the next few years. They're comparatively tiny--and may be key to hitting our climate goals.
