MARMOT Developer Receives Leadership Award

} The mechanistic smeared cracking model was extended from two to three dimensions (page 2). } Subcontinuum molecular dynamics simulations were used to investigate oxide fuel grain boundary fractures during reactor transients (page 2). } An improved model of bubble and grain boundary interaction was developed (page 2). } Improved descriptions of fission-gas/grain boundary interactions and cluster and defect formation are being developed to create new fission gas diffusion models in MARMOT (page 3). } The SHARP team has integrated structural mechanics feedback into coupled multiphysics dynamic simulations of sodium fast reactor (SFR) cores, with the sponsorship of the Advanced Reactor Concepts program (page 5). } The coupled simulation effort has driven debugging and other code improvements, as well as advances in mapping dissimilar computational meshes (page 5). } The MOOSE framework was updated with a robust capability to recover from processing interruptions (page 5). } The risk analysis capabilities of RAVEN were extended by importing the Boost library and implementing n-dimensional distributions (page 7). } Industry collaborators help improve the graphical user interface of RELAP-7 (page 7). } The flow model in the SFR System Module was updated (page 8).
