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.

FLiBe

FLiBe is a molten salt made from fused LiF and BeF2 salts at temperatures exceeding 732 K and is a proposed moderator, coolant, and heat storage medium for advanced reactor designs. FLiBe was modelled using classical molecular dynamics (MD) in the LAMMPS code. From the generated velocity autocorrelation function (VACF), the corresponding density of states (DOS) and liquid parameters were derived and used in FLASSH 1.0 to calculate the thermal scattering law (TSL).
