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.

Silicon Dioxide (SiO2)

Silicon dioxide (SiO2) is a major component of rock and earth and has significance in criticality safety applications including long term fuel and waste storage. Alpha- and beta-phase SiO2 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.
