Investigation of Doppler broadening methods within the Shift Monte Carlo radiation transport code

Funding

This work was completed in part through the Nuclear Engineering Science Laboratory Synthesis program at Oak Ridge National Laboratory. This material is based upon work supported under a University Nuclear Leadership Program Graduate Fellowship. This research was supported by the Exascale Computing Project (ECP), project number 17-SC-20-SC. The ECP is a collaborative effort of two DOE organizations, the Office of Science and the National Nuclear Security Administration, that are responsible for the planning and preparation of a capable exascale ecosystem-including software, applications, hardware, advanced system engineering, and early testbed platforms-to support the nation's exascale computing imperative.
