Analyzing the effect of pressure on the properties of point defects in gamma U-Mo through atomistic simulations
Uranium–molybdenum (U–Mo) alloys in monolithic fuel foil are the primary candidate for the conversion of high-performance research reactors in the USA. Monolithic fuel is utilized in a plate-type design with a zirconium diffusion barrier and aluminum cladding. These fuel types are unique in that they contain no plenum for the release of fission gases, which, […]
Computational determination of a primary diffusion mode in gamma U-10Mo under irradiation
Low enriched uranium (< 20 % 235U)-molybdenum (U-Mo) monolithic fuel is the primary candidate for high performance research and test reactors, and is in the process of being qualified to replace highly enriched uranium (= 20 % 235U) fuel. As part of the qualification process, it is critical to understand and predict the behavior of […]
Microstructural-Level Fuel Performance Modeling of U Mo Monolithic Fuel
As the physics that governs the microstructural evolution of nuclear fuel span various time and spatial scales, to fully understand the fuel behavior inevitably involves atomic to mesoscale resolution that can be difficult to determine experimentally. Microstructural-level modeling and simulations can be used to develop physics-based materials models that can provide physical understanding to inform […]
