NEAMS MeshKit module is capable of generating geometry and meshes that accurately describe the computational model for simulating a variety of nuclear reactors. MeshKit uses a graph-based process for specifying the overall meshing problem, with graph nodes representing meshing and other operations, and graph edges as dependencies between those operations. In our previous papers on Reactor Geometry (and Mesh) Generation (RGG) tool in MeshKit: basic working, examples of models generated using serial and parallel version of the tool were presented. In this paper, we briefly describe the MeshKit design philosophy and list currently available algorithms for Hex/Quad, Tet/Tri along and other helper-meshing algorithms in MeshKit. New keywords and features introduced to RGG are highlighted with the help of examples. Reactor assembly examples include the XX09 assembly used in Shutdown Heat Removal Tests (SHRT) that demonstrated passive safety features of EBR-II Experimental Breeder Reactor and an Advance Burner Test Reactor (ABTR) fuel assembly. Reactor core examples include the ABTR core model with restraint rings, homogenized High Temperature Gas-cooled Reactor (HTGR) and homogenized EBR-II core model with detailed XX09 assembly.
