The University of Florida Division of Sponsored Research was awarded a $799,999.00 Project Grant from the U.S. Department of Energy's Office of Nuclear Energy under the Nuclear Energy Research, Development and Demonstration program (CFDA 81.121). The three-year grant, which began on August 1, 2024 and runs through September 30, 2027, will fund research to develop a capability for concurrent generation and use of physics-informed Gaussian process surrogate models. This methodology will enable more efficient multi-scale and multi-physics modeling for applications relevant to nuclear reactor operations, such as fission gas diffusion, metallic cladding creep, and TRISO particle behavior. A sub-award of $954,643 was provided to The Johns Hopkins University to support tasks on customizing learning functions, developing physics-constrained surrogate models, and optimizing parallel performance of the new modeling approach, which will be implemented within the Multiphysics Object-Oriented Simulation Environment (MOOSE) framework.
