NuScale Power is commercializing a safe, modular, and scalable 50 megawatt electric (gross) light water reactor nuclear power plant.   NuScale plants are safe. Our design implements passive safety systems that use natural circulation for emergency feed water cooling, decay heat removal, and containment cooling. This eliminates the need for primary pipes and pumps.  NuScale plants are modular. Each component is modular and is designed for fabrication off-site at numerous existing facilities in the USA and around the world. The NuScale containment and reactor vessel measures approximately 65 feet in length and 14.5 feet in diameter. It and all other modular components are transportable by barge, truck, or rail.  NuScale plants are scalable.  Power generating capacity can be increased as needed by installing additional NuScale modules. This design allows for a single facility to have just one or up to 12 units. In a multi-module plant, one unit can be taken out of service without affecting the operation of the others.
