Nuclear Energy and Large-Scale Computing
DescriptionA transformation is underway in the world's energy sector. Tremendous growth in AI, data centers, and electrification is accelerating the need for new and expanded energy sources. Nuclear energy, with unparalleled bipartisan support, is seeing record-breaking private investment in both fission and fusion technologies and global commitments to expanding nuclear energy. Nuclear energy can be a key provider of energy for large-scale computing, and this talk will provide an overview of current activities and challenges in expansion to meet this rising need.

Nuclear energy is also a user of large-scale computing; accelerated deployment timelines are placing a growing importance on high-fidelity simulation to enable parameter exploration, design optimization, and safety analysis for regulatory compliance. The second part of this talk will describe the adoption of high performance computing for nuclear engineering applications, in particular focusing on the NEAMS (Nuclear Energy Advanced Modeling and Simulation) program, codes developed during the ExaSMR project under the Exascale Computing Project (ECP), and research activities at the University of Illinois.
