Efficient Multiphysics Coupling for Fast Burst Reactors in Slab Geometry
In this thesis, we discuss a coupling algorithm to model simplified fast burst reactor dynamics. Kadioglu presented a tightly coupled multiphysics algorithm of diffusion neutronics and linear. An implicit-explicit (IMEX) algorithm was used to follow the dynamical time-scale of the problem. However, …
