Revolutionary small modular nuclear reactors for space and earth applications starting in 2024


The three-year Kilopower safe 4 kilowatt nuclear reactor project started in 2015 with a challenging goal of building and testing a full-scale flight-prototypic nuclear reactor by the end of 2017 mid-2018.

Lessons learned from the kiloPower development program are being leveraged to develop a Mega Watt class of reactors termed MegaPower reactors. These concepts all contain intrinsic safety features similar to those in kiloPower, including reactor self-regulation, low reactor core power density and the use of heat pipes for reactor core heat removal.

The use of these higher power reactors is for terrestrial applications, such as power in remote locations, or to power larger human planetary colonies.

The MegaPower reactor concept produces approximately two megawatts of electric power. The reactor would be attached to an open air Brayton cycle power conversion system. A Brayton power cycle uses air as the working fluid and as the means of ultimate heat removal.
