SMR, LLC (Holtec)
The SMR-300 is an advanced, passively safe, pressurized light water nuclear power plant with 300 MW(e) rated net electric output. The SMR-300 is designed with forced circulation utilizing two cold legs each with a vertically mounted reactor coolant pump, two hot legs, and a single once-through steam generator (OTSG) with an integral pressurizer stacked on top of the OTSG. The use of reactor coolant pumps during normal operation is necessary to produce the rated power; however, the design utilizes passive, gravity driven safety systems that do not rely on pumps, external water, external power, or operator action.
