Idaho State University

What you'll study

The PhD programme combines advanced coursework with an independent, original research dissertation. Early study typically covers core topics such as reactor physics and neutron transport, thermal-hydraulics, radiation detection and measurement, nuclear materials and materials degradation, radiation protection and health physics, and nuclear systems engineering. Students also take courses in numerical methods, computational modelling (finite element/finite difference methods), and statistics for experiment and simulation.

• Core subject areas: reactor theory and neutron transport, thermal-hydraulics, radiation detection and dosimetry, nuclear materials and fuel behavior, reactor safety and regulatory aspects.
• Methodology and tools: computational methods for reactor analysis, Monte Carlo transport codes, multiphysics coupling, uncertainties and sensitivity analysis, experimental design and data analysis.
• Research: students undertake original research under faculty supervision, culminating in a written dissertation and oral defence. Research topics frequently include reactor core analysis, advanced fuels and cladding, radiation measurement systems, modelling of multi-physics phenomena, and applied reactor operations.

Programme structure is typical of doctoral degrees: advanced coursework to build depth, a qualifying or candidacy examination to demonstrate readiness for research, followed by a period of focused dissertation research and publication. Many students supplement their work through collaborations with nearby research facilities and national laboratories.

Entry requirements

Applicants are normally expected to hold a relevant masters degree in nuclear engineering or a closely related discipline (mechanical engineering, materials science, physics, or applied mathematics) with a strong academic record. Exceptional candidates with a bachelor's degree and outstanding preparation may be considered in some cases.

• Academic background: coursework in calculus, differential equations, linear algebra, engineering thermodynamics or fluid mechanics, and undergraduate-level nuclear engineering or physics is strongly recommended.
• Research experience: prior research, project work or thesis experience is highly desirable and strengthens an application.
• Supporting documents: statement of purpose outlining research interests, curriculum vitae, transcripts, and at least three letters of recommendation.
• English language: applicants whose first language is not English must meet the university's English proficiency requirements.

Additional requirements may include a faculty sponsor or expression of research interest aligned with departmental strengths. Check the department for specific application instructions and any optional testing requirements.

Career prospects

Graduates of the PhD in Nuclear Engineering pursue careers across academia, national laboratories, industry and government. Typical pathways include:

• Research scientist or engineer positions at national laboratories and research institutes working on reactor technology, fuel cycle research, materials testing, radiation measurement and safety.
• Faculty positions in universities and technical colleges, leading research groups and teaching undergraduate and graduate courses.
• Technical and managerial roles in the nuclear power industry and utilities, including core design, safety analysis, licensing support and plant operations.
• Regulatory and policy positions at governmental agencies and international organisations concerned with nuclear safety, safeguards and non-proliferation.
• Specialist roles in medical physics, radiation instrumentation, and industries using radioactive sources for research and manufacturing.

Why study at Idaho State University

Idaho State University offers a PhD environment with close ties to regional nuclear research infrastructure, providing opportunities for experimental and applied research in reactor and radiation science. The department maintains active research groups in reactor physics, thermal-hydraulics, materials behaviour under irradiation and radiation detection, supervised by faculty with experience in both academic and national-laboratory settings.

• Access to research facilities: students benefit from laboratory resources and collaborative arrangements with nearby national research organisations and test facilities, enabling hands-on experiments and large-scale simulation projects.
• Interdisciplinary collaboration: the programme supports cross-disciplinary work with materials science, mechanical engineering, health physics and computational science units, helping students develop applied, multi-physics research skills.
• Professional development: PhD candidates receive mentorship in grant writing, technical communication and preparing research for peer-reviewed publication, positioning them for leadership roles in research and industry.

Prospective students should contact the departmental graduate coordinator or potential faculty advisors to discuss research fit and available resources before applying.
