The Thermal Scattering Law Project

Harnessing modern methods for material modeling and high-fidelity thermal scattering evaluations, the Scattering Law Project provides access to nuclear thermal scattering data from fundamental inputs to benchmark testing on key reactor and nuclear criticality materials to inspire and support the next generation of nuclear applications.

Uranium Metal (U-metal)

Uranium metal (U-metal) is a form of metal plate type fuel and common material for cross section benchmark measurements. The stable room temperature alpha-phase U-metal was modelled using ab initio lattice dynamics (AILD) methods using the VASP and PHONON codes with the thermal scattering law (TSL) calculated using FLASSH 1.0. The data files generated for U-metal are generated for U-235 enrichments of 5%, 10% (LEU+), 19.75% (HALEU), 93% (HEU), 100%, and natural, representing the range of fuel enrichments applied for U-metal fuel and measurements.
