Overview
A Professor of Nuclear Science runs two parallel careers simultaneously: educator and researcher. Neither can be neglected. In the classroom, they teach the theory and application of nuclear science to students who will go on to operate reactors, regulate the industry, design fuel cycles, or push the physics further in laboratories. In the lab, they generate the original research that advances the field, trains the next generation of researchers, and justifies the institution's continued investment in nuclear science infrastructure.
On a typical week during the academic year, a junior faculty member might teach two courses — one undergraduate survey in reactor theory, one graduate seminar on neutron transport — hold office hours, run a group meeting with four or five PhD students, submit a progress report to DOE on an active grant, review a journal manuscript, and spend a half-day in the radiation lab supervising experimental work. Senior faculty carry more administrative load: department committee work, thesis committee obligations across other faculty's students, and the relationship management that keeps national lab collaborations funded and productive.
Research reactors remain the gold standard for experimental nuclear science education. Universities with licensed research reactors — MIT, University of Missouri, Penn State, Oregon State among them — have a meaningful competitive advantage in recruiting graduate students and winning experimental grants. Faculty at institutions without a reactor compensate through DOE user facility access, collaborations with national labs, and computational research programs.
The teaching dimension is more demanding than many candidates from industry or national labs anticipate. Developing a new graduate course from scratch takes a full semester of preparation. Managing a PhD student who is struggling with their dissertation requires patient, sustained mentorship. Undergraduates in nuclear engineering often need both technical guidance and career counseling in a field they've chosen partly on faith that it will grow. Faculty who are genuinely invested in that work thrive; those who treat it as a distraction from research usually struggle in peer review and promotion.
Institutional service — committee work, accreditation support, departmental administration — is the third leg of the faculty role. ABET accreditation reviews happen every six years and require substantial faculty time to document outcomes and prepare evidence. Faculty who dismiss this work push it onto colleagues and damage their standing in the department.

Career outlook
Nuclear science faculty positions are competitive, but the supply-demand dynamic is shifting in meaningful ways as the industry undergoes its most significant expansion since the 1970s.
Enrollment growth is real. Nuclear engineering undergraduate enrollment has grown each year since 2021, driven by renewed public interest in nuclear energy as a climate solution, high-profile SMR announcements, and strong starting salaries in the field. More students means more pressure on departments to hire faculty, particularly in areas directly relevant to advanced reactor design and the nuclear fuel cycle.
Retirements are creating openings. The generation of faculty who built up nuclear engineering programs in the 1980s and 1990s is retiring. Department heads who were hiring assistant professors in 2020 have told ANS audiences that they are struggling to fill positions — particularly in experimental reactor physics and nuclear thermal hydraulics, where the pipeline of qualified postdocs is thin relative to demand.
SMR and advanced reactor development is pulling talent. Companies like TerraPower, Kairos Power, X-energy, and Oklo are hiring PhD nuclear engineers faster than universities can produce them. This creates competitive pressure on academic salaries, but it also opens consulting and research collaboration opportunities that make faculty positions more attractive financially. Several universities have formalized research partnerships with SMR developers that bring industry funding into academic programs.
National security demand is persistent. NNSA programs supporting stockpile stewardship, nuclear nonproliferation, and detection technology employ nuclear science faculty both as principal investigators and as consultants on classified programs. Institutions with strong NNSA relationships — University of New Mexico, Texas A&M, University of Michigan — maintain faculty hiring pipelines connected to those programs.
The medium-term view is cautiously optimistic. If the SMR construction pipeline materializes as projected in the late 2020s, demand for trained nuclear engineers at every level will substantially exceed current academic output. Faculty positions created now will be producing graduates precisely when the industry needs them most. That alignment between academic investment and industry demand is genuinely unusual in engineering education.
Sample cover letter
Dear Search Committee,
I am applying for the tenure-track Assistant Professor position in Nuclear Engineering at [University]. I completed my PhD in nuclear engineering at [University] in May, where my dissertation focused on Monte Carlo uncertainty quantification methods for fast spectrum reactor design using OpenMC. I am currently in the second year of a postdoctoral appointment at Argonne National Laboratory's Nuclear Science and Engineering division, where I have been working on the neutronics benchmarking effort for the Versatile Test Reactor.
My research program as an independent faculty member will center on high-fidelity simulation methods for advanced reactor systems, with a near-term focus on validated neutronics models for liquid metal-cooled fast reactors. I have an active NEUP pre-application under review for FY2026 funding, and I have discussed potential joint appointments with two ANL staff scientists who are interested in continuing our collaboration through a university partnership agreement. I expect to be competitive for NRC Faculty Development funding in my second year.
In teaching, I am prepared to take on the core graduate neutron transport sequence immediately and to develop an advanced reactor design elective in my second year that reflects current SMR concepts rather than legacy PWR architecture. I taught a recitation section for the undergraduate reactor physics course for two semesters during my PhD and have received consistently strong student feedback on my ability to connect mathematical formalism to physical intuition.
I have reviewed [Department]'s research reactor operations and believe my background in experimental neutronics benchmarking would contribute directly to the reactor's utilization program. I would welcome the opportunity to discuss the position.

Frequently asked questions
- What degree is required to become a Professor of Nuclear Science?
- A PhD in nuclear engineering, nuclear physics, or a closely related field is required for tenure-track faculty positions at virtually all research universities. Some teaching-focused institutions hire candidates with a master's degree and extensive industry experience into lecturer or instructor roles, but the tenure track is closed without a doctorate. Postdoctoral research experience of two to four years is increasingly expected before a competitive tenure-track application.
- How important is grant funding to this career?
- At research universities, external grant funding is a core performance expectation — not a bonus. Faculty are typically expected to fund their own summer salary, support multiple graduate students, and cover laboratory operating costs through grants. NRC Faculty Development awards, DOE Nuclear Energy University Program (NEUP) grants, and NNSA Consortium for Verification Technology funding are the primary sources. Building and sustaining a grant portfolio is as important as publication record for promotion and tenure.
- What is the difference between a nuclear engineering professor and a nuclear physics professor?
- Nuclear engineering faculty focus on applied systems: reactor design, thermal hydraulics, fuel cycle, radiation shielding, and waste management. Nuclear physics faculty sit in physics departments and focus on fundamental properties of nuclei, particle interactions, and experimental techniques like accelerator science. The two communities overlap in areas like neutronics and nuclear data, and some departments span both through joint appointments.
- How is AI and computational simulation changing nuclear science research and teaching?
- High-fidelity simulation codes — OpenMC, SERPENT, RELAP5, and MOOSE — now allow students to model reactor behavior that previously required access to an operating reactor. Machine learning is being applied to reactor anomaly detection, fuel performance prediction, and nuclear data uncertainty quantification. Faculty who integrate these tools into both their teaching and research programs are attracting stronger graduate students and more competitive grants than those who don't.
- Are there opportunities outside traditional research universities for nuclear science faculty?
- Yes. National laboratories — Argonne, Oak Ridge, Idaho, Sandia — hire staff scientists with faculty-equivalent research roles and some teaching involvement through joint appointments. Navy nuclear academic programs, national security-focused institutions like the Naval Postgraduate School, and community colleges with nuclear technology programs all employ nuclear science educators. Industry research positions at companies like Kairos Power, TerraPower, and Westinghouse recruit PhD-level scientists into roles that blend research and technical leadership.
