Eigenvalue Solvers for Modeling Nuclear Reactors on Leadership Class Machines
R. N. Slaybaugh, M. Ramirez-Zweiger, Tara Pandya +2
Three complementary methods have been implemented in the code Denovo that accelerate neutral particle transport calculations with methods that use leadership-class computers fully…
Multigrid In Energy Preconditioner for Krylov Solvers
R. N. Slaybaugh, T. M. Evans, G. G. Davidson +1
We have added a new multigrid in energy (MGE) preconditioner to the Denovo discrete-ordinates radiation transport code. This preconditioner takes advantage of a new multilevel para…
FW/CADIS-: An angle-informed hybrid method for deep-penetration radiation transport
Madicken Munk, R. N. Slaybaugh, Tara M. Pandya +2
A new method for generating variance reduction parameters for strongly anisotropic, deep-penetration radiation shielding studies is presented. This method generates an alternate fo…
Improved Monte Carlo Variance Reduction for Space and Energy Self-Shielding
S. C. Wilson, R. N. Slaybaugh
Continued demand for accurate and computationally efficient transport methods to solve optically thick, fixed-source transport problems has inspired research on variance-reduction…
