Microreactors are small, low-power nuclear fission reactors that make less than 10 megawatts (MW) of electricity (or ~30 MW of heat). Numerous efforts to develop and deploy microreactors are ongoing with hopes to achieve breakthroughs in how nuclear power is utilized by humanity. They are characterized only by power level, and may use any coolant or moderator combination.
