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.

Calcium Hydride (CaH2)

As a metal hydride, calcium hydride (CaH2) is a potential moderator material in new reactor designs, including a small modular microreactors. CaH2 was evaluated using ab initio lattice dynamics (AILD) methods using the VASP and PHONON codes with the thermal scattering law (TSL) calculated using FLASSH 1.0.
