U.S. Leads Global Small Modular Reactor Development With 28 Siting Announcements

National laboratories account for seven announcements. Utilities, universities, and SMR developers each account for five announcements.

Small modular reactors are designed to produce up to 300 megawatts of electricity. Traditional reactors typically range from 1,000 to 1,400 megawatts. The smaller output allows deployment at data centers and remote locations where full grid connections are costly.

The U.S. total exceeds the combined announcements of the next four countries, according to the Nuclear Energy Agency. The agency tracks 129 SMR designs worldwide. Only 78 of those designs appear in its public dashboard. The remaining designs are either not publicly reported or are not under active development.
