Graduate Distance Learning Program in Nuclear and Radiation Engineering from The University of Texas at Austin

The distance learning program in graduate teaching and research has existed since 1999 in the Nuclear and Radiation Engineering (NRE) Program within the Walker Mechanical Engineering Department. It has served many graduate students in the national laboratories, industry and the Department of Defense who have sought advanced degrees while maintaining full time employment. The demographics of these students cover a wide range of ages from BSc recent graduates completing their MS/PHD degrees to those well along in their careers. The NRE distance learning program has matured into a well-disciplined entity with consistent, frequent student advising by faculty and comprehensive coverage of all NRE courses. We now offer experimental courses in Nuclear and Radiochemistry, and Gamma-Ray Spectrometry where the students take all the laboratory requirements in one weekend late in the semester while following the lectures on-line. Distance learning students who have graduated or are currently in the program are from Southwest Research Institute (San Antonio) , South Texas Project Nuclear Generating Station (Texas), Knolls Atomic Power Laboratory (KAPL), Bettis Atomic Power Laboratory, Sandia National Lab (Albuquerque and Livermore) , Pacific Northwest National Laboratory (PNNL), Brookhaven National Laboratory (BNL), Los Alamos National Laboratory (LANL), Oak Ridge National Laboratory (LANL), DoD (Army and Air Force), PANTEX, Department of Homeland Security, Sterigenics, MD Anderson Cancer Center, and Texas Department of Health Services Radiation Control Program.

Students apply directly to the program via the usual application process (http://www.me.utexas.edu/graduate-admissions/graduate-program/graduate-admissions-faq). Applications to the NRE program can be submitted throughout the year for a fall, spring or summer semester commencement. A minimum undergraduate GPA of 3.0 (although the typical incoming graduate student has higher GPA scores of 3.5 or better) is required along with very good Graduate Record Exams (GRE) scores. Typically, the applicant is considered on the basis of a combination of GPA, GRE, work experience, letters of reference, and a written statement of personal interest in the NRE Program. Students who have GPAs less than 3.0 or poor GRE scores are discouraged from applying. Since all the students are self-supporting they can apply off cycle and start in any semester. Students may transfer up to two courses from another university for the MS degree, if they have not been counted for a degree, but no courses are transferable for the PhD degree.

A comprehensive description of courses at the undergraduate and graduate levels is given in http://www.nuclear.engr.utexas.edu/current-students/courses. An undergraduate senior level course in Nuclear Power Systems is also offered for students with minimal nuclear engineering background and this course counts towards the MS degree. There is a two week intensive course given on campus called Radiation and Radiation Protection Laboratory (undergraduate) and Nuclear Health Physics Laboratory (graduate) which is not mandatory for the MS degree but strongly recommended for the PhD degree for those students who have never taken a course in nuclear instrumentation. Two courses in gamma-ray spectrometry and Nuclear and Radiochemistry are also offered with the off-campus students taking a series of laboratories over a weekend.

The Nuclear and Radiation Engineering program at The University of Texas at Austin has extensive experience delivering educational content to distance learning students. All the courses are digitally captured with Mediasite hardware and software. This software allows for simultaneous capture of the classroom computer display along with video and audio from the classroom. An example of such an output is seen on this web page. A Smartboard is utilized so instructors may write on the lecture slides and have the writing recorded in the digital video. To utilize the nuclear reactor for distance learning laboratories, in-house software has been developed providing a real-time remote display of the reactor conditions. Users may connect to this display via remote desktop, or a laboratory may be recorded with the Mediasite software. The software allows for recording of time-series data for numerous reactor parameters.

UT Student win Best Paper in Operations and Power at the ANS Student Conference

Jeongwon Seo and Sam Queralt won "Best Paper in Operations and Power" for their writing and presentation of "Efficiency Enhancement of Control Rod Worth Calibration in TRIGA Mk-II Reactor using Rod Swap Technique" at the ANS Student Conference in April. While current control rod calibration methods struggle to balance accuracy with efficiency, Rod Swap enables improvements in both. These new findings could be implemented at the university's own TRIGA reactor on the J. J. Pickle Research Campus. Until they are, this paper offers a new perspective on control rod worth calibration and invites further research in to improving the baseline operations of nuclear reactors.

Director of Strategic Nuclear Programs Represents UT at ReCENT's PowerUp Summit

Dani Zigon, Director of Strategic Initiatives for UT Austin's Nuclear and Radiation Engineering Program, delivered the opening keynote at Texas A&M's 2026 ReCENT Summit on April 28–29. The PowerUp program event brought approximately 500 middle and high school students to campus over two days for hands-on exposure to careers in clean energy and nuclear technology.

New NIH Trailblazer Award to Advance Robot-Assisted Imaging in Nuclear Medicine

The Translational Radiological Advanced Imaging Laboratory (TRAIL) in the Nuclear and Radiation Engineering Program within the Walker Department of Mechanical Engineering has been awarded a R21 Trailblazer Award from the National Institute of Biomedical Imaging and Bioengineering (NIBIB) of the National Institutes of Health (NIH). The grant will support the development of a novel, robot-assisted SPECT (Single Photon Emission Computed Tomography) imaging system, a project that seeks to redefine how high-resolution functional images of the human body are acquired.

Rethinking Nuclear Criticality Validation: Dr. Jeongwon Seo's Score Framework for Uncertainty-Aware Benchmark Selection

Dr. Jeongwon Seo’s latest paper, "Validation performance assessment through quantitative score focused on benchmark selection for nuclear criticality safety," has been published in Nuclear Science and Technology Open Research. While traditional validation relies on heuristic similarity rules, Dr. Seo introduces a "Score" concept that normalizes prediction residuals by their associated uncertainty. This provides an uncertainty-aware lens to ensure that model predictions are statistically consistent rather than just numerically close.
