The Pebble Bed Modular Reactor, or PBMR, is a High Temperature Gas Reactor that contains a large number of graphite fuel spheres that circulate in its core. The dynamics of these spheres, combined with thermal contraction and expansion, causes various loading cases on the reactor structures. A Distinct Element Method, or DEM, as implemented in the Particle Flow Code in 3D, or PFC{sup 3D}, is used at PBMR (Pty) Ltd to model the fuel sphere dynamics in the reactor core. This paper presents a few exploratory studies where PFC{sup 3D} was used to investigate the interaction between fuel spheres and structural components in the PBMR, as well as the packing efficiency of the spheres in the core.
