Fission

Summary

Nuclear fission has powered the world for decades, and it is now entering a transformative era. Researchers in MIT’s Department of Nuclear Science and Engineering are advancing next-generation reactor technologies that promise to reshape nuclear power’s role in a low-carbon energy future. Faculty and students are pioneering new designs that improve safety, lower costs, and integrate flexibly with renewable energy sources. Their work spans cutting-edge developments in reactor physics, thermal-hydraulics, materials, and fuel cycles—contributing to the evolution of both advanced systems and existing nuclear infrastructure. These innovations aim to expand the impact of fission technology across electricity generation, process heat, and clean hydrogen production.
