VHTR

Full VHTR core mesh and geometry models can be created using RGG tools. The mesh model has 21M hexes, it takes 96mins (serial run) and 3.5GB of RAM to generate the all assemblies and core mesh from scratch. For this mesh model axial mesh interval (Z-direction) of 2 is used. The geometry model has ~33,000 volumes. Isometric view of full VHTR core geometry (left), zoomed cross-sectional view of...

XX09 an SFR Fuel Assembly

Pictures below describe the meshing of instrumented XX09 assembly used in Shutdown Heat Removal Tests (SHRT) that demonstrated passive safety features of the EBR-II Experimental Breeder Reactor. The specic test from which this problem is derived is SHRT17, which is a Loss of Flow with SCRAM experiment. This test conguration was selected for the multi-physics demonstration because of the...
