NE Colloquium. Randy Baker - Los Alamos National Laboratory

Los Alamos National Laboratory is a large, multi-disciplinary laboratory with a diverse portfolio of missions in national defense, global security, open science, and many other areas. The Computational Physics Group (CCS-2) at LANL helps support these mission areas through both software packages and applications expertise. This talk will present a general overview of the Lab and CCS-2, a somewhat more detailed look at the radiation transport projects within CCS-2 (IMC, deterministic thermal radiation transport, and deterministic neutron/gamma transport), then review in detail what we're currently working on with PARTISN (moving material corrections, probability of initiation, neutron/fission population moments, large-scale parallel calculations, improved parallel sweeps, one-sided MPI, sub-critical experiments, future architectures, self-shielding), ending with possible future research topics (anisotropic fission, neutron-neutron scattering, etc.).
