Bundle Builder
   Software program to easily build
    transport code input decks for modern
    LWR configurations
    PWR
    BWR
    2-D and 3-D Configurations
   Currently supports MCNP[1] and
    PARTISN[2], input decks but can be
    easily extended to other codes
Bundle Builder Input
 Lattice and pin pitch
 Channel box description
 BWR control blade description
 Pin descriptions (radii and materials)
 Fuel description (enrichment)
 Pin maps
 Axial Description
 Material Compositions
Bundle Builder Output
   MCNP Input files
    ◦ Various tally options
    ◦ Post-processor to examine tallies
   PARTISN Input files
    ◦ Post-processor to convert PARTISN
      binary files to SILO/HDF format, which
      can be VISIT[6] Visualization Software
