Nuclear engineering is the branch of engineering concerned with breaking down atomic nuclei through fission or combining them through fusion to release usable energy. It spans the design, operation and maintenance of systems and components such as nuclear reactors, power plants and radiation equipment, and it draws on physics, chemical engineering and electrical engineering. Programmes in nuclear engineering cover research, development and the practical application of nuclear energy across power, medicine and industry.
What Is Nuclear Engineering?
Nuclear engineering is the branch of engineering that harnesses energy released from nuclear reactions, either splitting atomic nuclei through fission or joining them through fusion. It covers the design, construction, operation and maintenance of systems such as nuclear reactors, power plants and radiation equipment, drawing on physics, chemical engineering and electrical engineering principles.
The discipline studies sub-atomic physics and the behaviour of fissile materials and fission systems. Coursework typically includes fission and fusion systems, reactor design and physics, radiation science, nuclear fuels and fuel cycles, radiation shielding, and medical applications of nuclear technology. A B.Tech in Nuclear Science and Engineering is one of several undergraduate routes into the field, alongside postgraduate specialisations at leading universities.
What Do Nuclear Engineers Do?
Nuclear engineers research and develop the processes, instruments and systems used to derive benefits from nuclear energy and radiation. They design reactor cores, radiation shielding and safety systems, operate power plants, and work on medical and industrial applications. Many are employed by the nuclear power industry, national laboratories and government research organisations.
Much current research aims to produce economical, proliferation-resistant reactor designs with passive safety features. National laboratories also work on nuclear fuels and fuel cycles, advanced reactor concepts, and nuclear weapon design and stewardship. Beyond industry and laboratories, nuclear engineers contribute to academia as lecturers, professors and researchers, and support medical, space and imaging applications that rely on radiation and nuclear physics.

Several US universities lead nuclear engineering education and research. The Massachusetts Institute of Technology, University of California, Berkeley, University of Michigan and North Carolina State University all run highly ranked departments with dedicated research reactors and laboratories. The University of Florida also hosts one of the largest nuclear engineering programmes in the country.
MIT's Department of Nuclear Science and Engineering conducts research across fission, fusion and plasmas, quantum engineering and materials in extreme environments. UC Berkeley's department partners with the neighbouring Lawrence Berkeley National Laboratory, while North Carolina State University is home to the first nuclear engineering curriculum and the first non-governmental research reactor in the United States. The table below summarises leading programmes.
| University 2026 | Location | Notable Nuclear Strength |
|---|---|---|
| Massachusetts Institute of Technology | Cambridge, Massachusetts | NSE department; fission, fusion and quantum research |
| University of California, Berkeley | Berkeley, California | Top-ranked; partners with Lawrence Berkeley National Lab |
| University of Michigan | Ann Arbor, Michigan | NERS department among the top US programmes |
| North Carolina State University | Raleigh, North Carolina | First US nuclear engineering curriculum and reactor |
| University of Florida | Gainesville, Florida | One of the largest US nuclear engineering programmes |
What Is the Job Outlook for Nuclear Engineers?
The US Bureau of Labor Statistics projects employment of nuclear engineers to decline about 1 percent between 2024 and 2034, yet around 800 openings are expected each year, mainly to replace workers who retire or change occupations. Demand continues from maintaining existing power plants, national laboratories and advanced reactor research.
Although employment growth is expected to be flat, nuclear engineers remain essential to operating and maintaining the existing fleet of power plants, and to work on renewed interest in small modular reactors and advanced reactor designs. Nuclear engineers also find opportunities in national laboratories, defence, medical physics, space technology and academia, where they research, teach and support the safe use of nuclear technology.
