What you'll study

The MIT Nuclear Engineering master’s combines core coursework, electives, laboratory experience and a research or project thesis. Core topics typically include reactor physics and dynamics, radiation transport and shielding, thermal-hydraulics and heat transfer, nuclear materials and fuel behaviour, radiation detection and measurements, and computational techniques for multiphysics simulation.

• Core modules: neutron transport and reactor theory, reactor kinetics and control, thermal-hydraulics, radiation effects in materials, and radiation protection.
• Electives and specialisms: nuclear fuel cycle and waste management, fusion science and plasma engineering, advanced reactor design (including small modular reactors), probabilistic risk assessment, nuclear policy and non-proliferation, and medical/industrial applications of radiation.
• Computational practice: courses and projects emphasise numerical methods, Monte Carlo and deterministic transport codes, multiphysics coupling, data analysis and uncertainty quantification.
• Laboratory and research experience: hands-on experiments in reactor physics and radiation detection, access to facilities such as the Department’s research reactors and collaboration with the Plasma Science and Fusion Center for fusion-related work.
• Thesis or project: students complete an independent research thesis or an equivalent substantial design/project report under faculty supervision, integrating coursework and original investigation.

Entry requirements

Applicants are expected to hold a bachelor’s degree in engineering, physics, applied mathematics or a closely related quantitative discipline with strong performance in mathematics, calculus-based physics and introductory engineering science. Typical preparation includes coursework in differential equations, linear algebra, thermodynamics, fluid mechanics and basic nuclear or reactor physics where available.

• Academic record: a strong undergraduate GPA from a recognised institution.
• Supporting documents: academic transcripts, a statement of purpose outlining research interests and career goals, curriculum vitae, and letters of recommendation from academic or professional referees.
• Research or practical experience: prior laboratory work, internships or project experience in nuclear or related fields is highly desirable and can strengthen an application.
• English proficiency: applicants whose first language is not English should demonstrate proficiency through accepted tests or equivalent evidence, in line with Institute requirements.
• Other considerations: suitability for the programme is assessed holistically; applicants with non-traditional backgrounds may be considered if they demonstrate the necessary quantitative preparation and motivation.

Career prospects

Graduates of MIT’s Nuclear Engineering master’s enter a wide range of technical and policy roles. Common career paths include positions in nuclear power utilities and vendors, national and international research laboratories, regulatory and safety organisations, and engineering consultancies. Technical roles often focus on reactor design and analysis, safety assessment, materials performance, radiation protection and shielding, and computational modelling.

• Research and development: employment at national laboratories, private R&D centres or continuation to PhD study in academia or industry-led research.
• Industry and operations: roles in reactor engineering, plant operations support, licensing and safety analysis, and SMR or advanced reactor development.
• Regulation and policy: work with governmental and international agencies on safety standards, non-proliferation and nuclear regulatory frameworks.
• Cross-disciplinary opportunities: medical physics, radiation instrumentation, aerospace applications, and high-performance scientific computing.
