U.S. Dominates Global Small Modular Reactor Development

National laboratories are spearheading this domestic expansion with seven siting announcements, while utilities, universities, and private developers each account for five. These projects target the deployment of reactors capable of producing up to 300 MWe, a significant reduction from the 1,000–1,400 MWe output typical of conventional plants. The focus on modularity allows for mass factory manufacturing, intended to slash build times and capital costs that have historically hindered nuclear adoption.

The strategic shift toward SMRs addresses the growing demand for flexible, clean energy capable of supporting data centers and isolated regions where traditional grid infrastructure remains impractical. By prioritizing light water, fast neutron, graphite-moderated, and molten salt designs, developers are creating a portfolio that emphasizes transportability. As energy security and grid reliability become central to national policy, these siting patterns serve as a blueprint for long-term power strategy.
