199 Assembly Homogenized ABTR Core Viewed Using RGG Nuclear GUI

RGG is an open source tool for generating several types of nuclear reactor assembly/core geometry and mesh. Two specific mesh operations implemented as per the graph-based approach are AssyGen and CoreGen. Reactor core model generation can be broken into three steps: assembly geometry creation (AssyGen), assembly meshing (AssyGen+CUBIT/MeshKit-Algorithms) and core mesh creation (CoreGen).



OUTLINE:
  1.  Introduction to MeshKit
  2. MeshKit design philosophy
  3. Graph-based mesh generation technique
  4. Details and examples of algorithms and tools available in MeshKit
  5. RGG’s 3-stage reactor core geometry and mesh generation technique
  6. AssyGen program details and options
  7. CoreGen program details and options
  8. Using RGG Nuclear GUI:
    -a. Load existing RGG models, this includes KAIST PWR, 1/6th VHTR and other simple test examples
    -b. Create a rectangular assembly and core model from scratch (AssyGen/CoreGen input file creation)
    -c. Create a hexagonal assembly and core model from scratch (AssyGen/CoreGen input file creation)
    -d. Running RGG tool chain to create the meshes and load to check material and boundary conditions available in the model
