New US supercomputer to speed up nuclear reactor modeling, deployment

Idaho National Laboratory (INL) has launched its latest supercomputer, Teton, which quadruples the lab’s high-performance computing capacity and ranks as the 85th most powerful supercomputer globally according to TOP500. Teton, powered by AMD’s EPYC 9005 “Turin” processors and featuring 1,024 compute nodes with nearly 400,000 CPU cores, delivers 20.8 quadrillion calculations per second—four times the performance of its predecessor, Sawtooth, while occupying only one-third the physical space. This significant upgrade enables researchers to run complex modeling and simulation codes much faster, reducing computational tasks from days to hours. Designed specifically to accelerate nuclear reactor design and deployment, Teton supports the US Department of Energy’s Nuclear Science User Facilities (NSUF) by providing the computational power necessary for advanced reactor research. Its capabilities facilitate thousands of simulations to create Reduced Order Models (ROMs), which serve as accurate digital twins for optimizing reactor designs, speeding up
