NN Asks: How can university faculty help the nuclear industry meet GenAI-era energy demands?
Pavel Tsvetkov
This question is the one that we ask and answer every day. University faculty are uniquely positioned to bridge the gap between generative AI capabilities and the nuclear industry’s evolving energy challenges. By leveraging our expertise in research, education, and collaboration, faculty can drive advancements in nuclear technology, cultivate a skilled workforce, and foster public and industry support.
There is no industry without a skilled, well-educated workforce. At Texas A&M’s Department of Nuclear Engineering, we nurture our students through a very comprehensive and rigorous nuclear engineering program, which has a critical impact on the nuclear industry as those students enter the workforce. As nuclear industry demands grow, so too our student population is growing. We are approaching 200 graduate students and 400 undergraduate students in our programs.

Group 5 metals (V, Nb and Ta) are potential candidates of tube material in vacuum permeator for tritium recovery from Pb-17Li liquid blanket system. From this viewpoint, the influence of oxygen on the surface reaction rates of hydrogen on V and Ta were examined in an ultra-high vacuum apparatuses at elevated temperatures, and the results were compared with the data on Nb acquired in a previous study. The surface reaction rates of hydrogen on V and Ta, and consequently permeation rates, decreased with increasing oxygen concentration in the bulk as previously observed for Nb. These observations were ascribed to the increase in surface oxygen coverage with increasing bulk oxygen concentration. The weakest influence of oxygen on hydrogen permeation rate was observed for V. The expected permeation rate through V under typical blanket conditions, however, was not necessarily high due to high oxygen solubility in V. The evaluation indicated that the highest permeation rate should be obtained with Nb under typical blanket conditions.
