The remote, automatic, real-time adjustment of a research reactor’s power by a geographically distributed control system has been reported by researchers from Idaho National Laboratory, the Grainger College of Engineering at the University of Illinois–Urbana-Champaign, and Purdue University. The investigators first used an automatic adjustment “digital control loop” system to demonstrate remote adjustments of Purdue’s PUR-1 research reactor. They then applied a reinforcement learning model that simulates the interaction of physical forces inside the reactor, making the loop system more autonomous.

BWX Technologies and Purdue University have signed a memorandum of understanding to collaborate on research focused on next-generation nuclear technologies, including small modular reactors and microreactors.

Kim

Recently, Nuclear Engineering Department Heads Organization Chair Seungjin Kim talked with Nuclear News about NEDHO’s current condition, governmental funding for NEDHO and university research, the impact of artificial intelligence and other technologies in the classroom, the influence of advanced reactors in nuclear engineering education, and other issues.

Kim, who is an ANS Fellow, is the Captain James F. McCarthy Jr. and Cheryl E. McCarthy Head of Nuclear Engineering at Purdue University, in West Lafayette, Ind. He began his 2025–2026 term as NEDHO chair earlier this year. He took over from the previous chair, Sukesh Aghara, professor and director of the Nuclear and Chemical Engineering Department at the University of Massachusetts–Lowell.

A research reactor built in 1962 that was converted to digital control and operation in 2019 is aiding the development of advanced nuclear reactors, such as small modular reactors and microreactors. An article published by Purdue University describes how Purdue University Reactor Number One (PUR-1), currently the only facility to be licensed for a fully digital safety and control system by the Nuclear Regulatory Commission, is being used to perform “first-of-a-kind experiments that are unique to the nuclear sector.”

“SMRs present a viable opportunity for Indiana to transition to a cleaner, resilient, and diversified energy future. Successful deployment of SMR technology requires a careful balance of economic, regulatory and social considerations along with development of the technology.” Those are among the conclusions of a comprehensive study conducted on small modular reactors primarily by researchers at Purdue University and funded by the Indiana Office of Energy Development.

Purdue University’s School of Nuclear Engineering is hosting a two-day Atoms for Humanity symposium on campus at the Stewart Center’s Eliza Fowler Hall on October 25–26. The symposium—which will take place from 10:00 a.m. to 6:00 p.m. (EDT) on the first day and from 10:00 a.m. to 5:00 p.m. (EDT) on the second day—will highlight the role of nuclear energy as a clean energy source. It is open to everyone, and no registration is required.

Purdue University and Duke Energy released an interim report on May 10 that documents the first year of an ongoing feasibility study, first announced in April 2022, that could help bring nuclear power to the state of Indiana. No technology has been selected and no decision to build a new nuclear plant has been made at Purdue University or elsewhere in the state, but in the Small Modular Reactor and Advanced Reactor Feasibility Study Interim Report the study participants conclude that “small modular reactors and advanced reactors are a viable option that warrant continued exploration to meet the future carbon-free energy needs of Purdue University and Duke Energy Indiana.”

Magwood

As part of the Purdue University–Duke Energy Understanding Tomorrow’s Nuclear Energy lecture series, William D. Magwood IV, director general of the OECD Nuclear Energy Agency (NEA), delivered a lecture on October 24 at the Purdue Memorial Union Ballrooms. “The 21st Century Nuclear Resurgence: Opportunities and Challenges” was the third lecture in the series, which focuses on small modular reactors.

Magwood reviewed the factors that have led to the current increased interest in nuclear energy around the world, the serious challenges that must be quickly and adequately addressed, and the structural barriers that require new thinking by regulators and policymakers. He also commented on the ongoing Purdue-Duke study of the feasibility of using SMRs to meet the West Lafayette campus’s long-term energy needs.

Bement

The new Understanding Tomorrow’s Nuclear Energy lecture series, sponsored by Purdue University and Duke Energy, premieres on August 30. The first scheduled speaker, Arden L. Bement Jr., professor emeritus of nuclear engineering at Purdue, will deliver a talk titled “Clean Nuclear Energy: Past, Present, and Future.”

Register now. Participants can attend the event, from 4:00 to 5:00 p.m. EDT, either in person or virtually. The presentation will be delivered in the Stewart Center Fowler Hall on Purdue’s campus in West Lafayette, Ind. Advance registration is required for this free lecture.

What’s it about: The series will feature community leaders speaking on the feasibility of using advanced nuclear technologies to meet the long-term zero-carbon energy goals of the West Lafayette campus. It is designed to appeal to everyone, from nuclear industry experts to community residents with a general interest in the topic.

A new lecture series launched by Purdue University and Duke Energy is designed to educate the public about small modular reactors and other advances in nuclear energy. The series stems from an ongoing comprehensive joint study by Purdue and Duke, announced in April, which is investigating the feasibility of using SMRs to meet the campus’s energy needs.

Purdue University and Duke Energy have announced that they plan to jointly explore the feasibility of using advanced nuclear energy to meet the university’s long-term energy needs, “a move that may be unprecedented for a college campus.” A small modular reactor could meet the current and future needs for Purdue’s West Lafayette, Ind., campus, as well as provide excess power to the state’s electric grid, according to a joint press release.

Research into the high-resolution detection of plutonium mixtures by Purdue University professor Rusi Taleyarkhan and his team was featured on the cover of the February issue of the Journal of Analytical Atomic Spectroscopy, published by the British Royal Society of Chemistry.

The published research focuses on novel hybrid mass-alpha spectroscopy technology. Taleyarkhan and his team applied centrifugally tensioned metastable fluid detector sensor technology to the detection of mixtures of plutonium-239/240. This technology can serve as an alternative to conventional alpha radiation spectroscopy sensors and to mass spectroscopy systems, which can take weeks to deploy and are cost-prohibitive, especially when deployed in low-radiation fields for long periods of time.

The Nuclear Regulatory Commission announced on November 15 that it has awarded nearly $5.5 million in grants to support research and development activities in nuclear science, engineering, technology, and related disciplines under the University Nuclear Leadership Program (UNLP), previously known as the Integrated University Program.

This month’s issue of Nuclear News focuses on the role of probabilistic methods in assessing and mitigating the risk of adverse events at nuclear plants and facilities. It’s a timely topic as we move to launch a new generation of nuclear technologies, but it is only half of a larger question that is universal to the human condition: Are the rewards of a particular thing worth its attendant risks?

Nuclear engineers use hard technical terms like “probabilistic risk assessment” and “core damage frequency,” but other industries have much more colorful ways of describing the holistic risk-reward construct in their world. In finance, it’s known simply as “alpha.” A zero alpha investment suggests that its returns are commensurate with the associated risks. Negative alphas get pushed to the curb, and “high alpha” deals get Wall Street hedge fund managers their house in the Hamptons.

A team of researchers led by Purdue University has used X-ray imaging conducted at Argonne National Laboratory’s Advanced Photon Source to obtain a three-dimensional view of the interior of an irradiated nuclear fuel sample. The use of synchrotron micro-computed tomography could lead to more accurate modeling of fuel behavior and more efficient nuclear fuel designs, according to the researchers.
