Nuclear Materials Student Working in Lab

Nuclear Power

We are enabling the safe and economical operation of nuclear reactors.

Our researchers focus on reactor engineering and core design, fluid flow and heat removal from the core, accident analysis, and the degradation mechanisms suffered by nuclear fuel and materials while in service. Research areas include nuclear materials, reactor controls, reactor thermal hydraulics, and reactor physics.
