NSUF 17-CINR-12853: HPC Access to Advance Understanding of Fission Gas Behavior in Nuclear Fuel

The outcome of this project will be improved insight into the atomistic processes of Xe diffusion and clustering, along with gas re-solution by energetic fission fragments; and the development of a leadership class fission gas simulator, Xolotl-fission, for modeling the spatially dependent bubble population evolution within nuclear fuel. Ultimately this will lead to the development of physically-motivated, computationally benchmarked and experimentally validated engineering-scale models of fission gas release to be used in fuel performance codes like BISON.
