Computational Methods

Principal Investigator Kord Smith


The implementation of reactor physics methods into efficient simulation tools requires effective computational methods and numerical algorithms. Students are engaged in extending a class of non-linear acceleration techniques recently developed for deterministic applications (physics-based multi-grid methods) to stochastic Monte Carlo neutral particle transport. Multi-physics coupling of neutron transport, fluid flow, and fuel modeling with Krylov solvers is being pursued for large-scale reactor simulations. These methods hold promise for not only providing efficient acceleration for Monte Carlo calculations, but also for extending Monte Carlo applications to the time domain.
