Improving the reliability and interpretability of computational models used to analyze nuclear reactors earned Zeyun Wu, Ph.D., associate professor in the Virginia Commonwealth University Department of Mechanical & Nuclear Engineering, the Untermyer & Cisler Reactor Technology Medal from the American Nuclear Society.

The Untermyer & Cisler award honors individuals who have made outstanding scientific, engineering or management contributions to the advancement of nuclear reactor technology. Wu's research bridges fundamental reactor physics with practical reactor engineering applications used in the development of advanced reactor designs.

Wu said he was honored by the recognition.

"This award reflects the support of my students, collaborators and the outstanding environment within VCU's Department of Mechanical & Nuclear Engineering and the College of Engineering," Wu said. "I look forward to continuing to advance reactor technologies that will play a key role in the future of nuclear energy. I am especially grateful for the support of my wife and son. Their encouragement and understanding have been invaluable, and this recognition is as much theirs as it is mine."

Working at the intersection of several traditionally separate areas, Wu connects high-fidelity physics modeling with system-level behavior, which is increasingly important for next-generation nuclear technologies. He is also involved in developing benchmark problems and community tools that help standardize and validate reactor analysis methods, enabling broader adoption across academia, national laboratories and industry.

Wu's work ranges from computational methods to neutron transport, uncertainty quantification and reactor safety analysis.

"This medal recognizes Dr. Wu's substantial contributions to the field of engineering, particularly in the development of new nuclear reactor technology," said VCU Nuclear Program Director Gennady Miloshevsky, Ph.D. "It highlights that the nuclear engineering program at VCU is progressively concentrating on advanced reactor designs and computational modeling, thus preparing students for careers in nuclear power engineering."

Rather than developing methods in isolation, Wu's approach directly addresses real-world engineering challenges associated with nuclear data uncertainties, reactor safety margins and complex multiphysics interactions.
