Nuclear engineering is a research area focused on the analysis, design, optimization, and safety assessment of systems that exploit nuclear processes, primarily fission and, increasingly, fusion. It encompasses reactor physics, thermal-hydraulics, fuel cycle science, radiation transport, materials behavior under irradiation, and nuclear instrumentation and control. Research addresses core design, neutron economy, transmutation, waste minimization, and proliferation resistance, as well as severe-accident phenomenology and probabilistic risk assessment. Contemporary nuclear engineering also investigates advanced reactor concepts (e.g., fast reactors, high-temperature reactors, small modular reactors), fuel and cladding innovations, fusion plasma-facing components, and nuclear data evaluation to support both power generation and non-power applications such as medical isotope production and radiation technologies.
Nuclear propulsion and power technologies could unlock new frontiers in missions to the moon, Mars, and beyond. NASA has reached an important milestone advancing nuclear propulsion that could benefit future deep space missions ...

Billions of alkaline-loving microbes could offer a new way to protect nuclear waste buried deep underground. This approach overcomes the limitations of current cement barriers, which can crack or break down over time.
In a bold, strategic move for the U.S., acting NASA Administrator Sean Duffy announced plans on Aug. 5, 2025, to build a nuclear fission reactor for deployment on the lunar surface in 2030. Doing so would allow the United ...
