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.

Hydrofluoric Acid (HF)

Liquid anhydrous hydrogen fluoride (HF) is a material commonly used in fuel manufacturing and processing, and as a result it is of particular interest for criticality safety applications. HF was modelled using classical molecular dynamics (MD) using the GROMACS 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).
