The Carbon Free Power Project's was going to build a NuScale nuclear fission reactor at the Department of Energy's Idaho National Laboratory (INL). A site license was issued in 2016.

The NuScale small modular reactor (SMR) offers a scalable power plant solution incorporating enhanced safety, improved affordability, and extended flexibility for diverse electrical and process heat applications.

The NuScale Power Module™ (NPM) is a 77 MWe integral pressurized water reactor (PWR) that employs gravity-driven natural circulation of the primary coolant for both normal operation and shutdown mode.

The NPM, including containment, is fully factory-built and shipped to the plant site by truck, rail, or barge without the need for field fabrication, erection, or construction.
