Nuscale Power Corp
A designer of small modular nuclear reactors, NuScale makes compact, factory-built power units called NuScale Power Modules that utilities can group together to generate electricity and heat for homes and industry. The technology was born in the labs of Oregon State University, where engineer José Reyes studied a reactor that cools itself by natural circulation rather than pumps; he and Paul Lorenzini spun it out into a company in 2007. The name "NuScale" plays on that "nuclear, scaled down" idea — its reactors are roughly one-hundredth the size of a traditional nuclear plant.
