On a good day, the fuel in a typical nuclear reactor is stationary. For a circulating fuel reactor, the opposite is true - the fuel moves. This movement results in significant changes to the models underlying the reactor kinetics of circulating fuel concepts relative to their stationary cousins. Simulating these systems with full time-, space-, angle-, and energy-dependence can be a computationally expensive undertaking. QuasiMolto, an open-source computational tool for circulating fuel reactor kinetics, utilizes a multilevel methodology to simulate these multiphysics systems efficiently. This seminar will offer a primer on radiation transport, describe the finite-volume, multilevel methodologies that underpin QuasiMolto, and present preliminary simulations of the Molten Salt Reactor Experiment.

BIO: Aaron Reynolds is a Postdoctoral Scholar at Oregon State University's Center for Exascale Monte Carlo Neutron Transport (CEMeNT). His research interests include methods development and verification in the context of reactor physics, multiphysics coupling, multilevel approaches, and high-performance computing. Currently, his efforts at CEMeNT focus on time-dependent Monte Carlo neutron transport methods to be used on modern computing architectures. He enjoys bread, science fiction, and, to the misfortune of his neighbors, the banjo. Paddle faster.
