The team will leverage new high-resolution data, made possible by Graphics Processing Unit (GPU) computing, to develop efficient thermal hydraulics systems analysis methods. The team will also integrate Large Language Models to streamline the multiscale framework and foster industry adoption. |

This builds upon the recent NEUP IRP project (20-22094) that was focused on pebble bed fluoride salt cooled high temperature reactors Fluoride Salt-Cooled High-Temperature Reactor (FHR) and historical prismatic Modular High-Temperature Gas-Cooled Reactor (mHTGR) designs. |

The team will develop methods based on machine learning to improve both the resolution and signal-to-noise ratios of passive multimodal tomography images. This work will dramatically enhance the sensitivity of dry cask imaging technologies that are essential for the long-term sustainability of nuclear power in the United States. |

This project seeks to optimize and scale-up this new approach, combined with multi-scale modeling for the prediction of radiolytic ligand longevity and degradation product formation over time, so as to augment at-scale engineering models in support of future process implementation. |

This correlation can be turned into design principles to further improve the irradiation performance of TRISO by controlling initial buffer microstructure. |
