Applied Atomics is a company that develops, builds, and operates medium modular nuclear fission plants (100 MW to 1 GW) as turnkey, on-site power facilities. They offer end-to-end execution — licensing, construction, and operation — with a single power purchase agreement so customers (datacenters, industrial campuses, and utilities) receive dedicated, clean baseload power without running the plant themselves. Applied Atomics uses proven light-water reactor architecture and has secured an exclusive land-based license for the mPower™ small modular reactor technology from BWX Technologies, positioning itself as a B2B provider of site-dedicated nuclear power solutions.
