  1. Introduction to HELIOS T. K. Kim Argonne National Laboratory

  2. Overview of HELIOS • Expert input • Described by parameters • Not sensitive to geometry or composition data • Short input • Assign value to parameters • Sensitive to geometry and composition data HELIOS General 2D geometry subgroup resonance method current coupling collision probability method AURORA Input processor ZENTIH Output processor HERMES file (data base file)

  3. Flow Diagram of AURORA-HELIOS-ZENITH AURORA Expert input AURORA Short input ZENITH Expert input AURORA AURORA create create AURORA SETs (HERMES file) ZENITH SETs (HERMES file) AURORA update ORION AURORA SETs (HERMES file) ZENTIH Picture (postscript) create create update Output (ASCII) HELIOS

  4. Methodologies • CPM in structure • STR consists of region and circular geometry (CCS) • Region is defined by nodes • CCPM between structures (CNX) • Assign current coupling order • Boundary condition (BDRY) • Reflective or Albedo conditions
