About the employer

NuScale Power

Power for all humankind

NuScale has designed a new kind of nuclear power plant that is smarter, safer, cleaner, and more cost competitive than the large gigawatt nuclear power plants of the past.

At the heart of the NuScale power plant is the NuScale Power Module™ (NPM), a small modular reactor (SMR) that brings together traditional components—the reactor vessel, steam generator, pressurizer, and containment—into a single, simplified, and fully factory-fabricated unit. Each NPM can produce 77 megawatts of electricity (MWe), and one NuScale plant can house up to 12 NPMs for a total of 924 MWe (gross). This scalability feature is unique to NuScale and allows for customization of facility output to match demand and project economics. NuScale has achieved a paradigm shift in the level of safety of a nuclear power plant facility—safety comes first, second to none. NuScale’s Triple Crown for Nuclear Plant Safety™ design ensures that on loss of all electricity to the power station, an undesirable situation for other nuclear plant designs, each NPM will safely shut down and self-cool, indefinitely, with no need for operator or computer action, AC or DC power, or additional water. This capability is a first for commercial nuclear power.
