Small modular reactors and microreactors under development in the United States ›

Electric utilities in the United States currently operate about 98 gigawatts (GW) of nuclear generating capacity, but very little nuclear capacity has been built in the last few decades. High capital costs and lengthy licensing and approval processes have limited the expansion of nuclear power. However, several companies are developing new small modular reactor (SMR) designs aimed at reducing capital costs and increasing siting flexibility, challenges associated with traditional nuclear power.
