The Nuclear V&V packages were developed under Archon's 10CFR50 Appendix B, and ASME NQA-1, 1994 quality assurance program allowing Archon to provide these packages via a nuclear safety-related purchase order.

Use with:

• Fathom, Fathom GSC Module, Fathom XTS Module
• Arrow and Arrow GSC Module 
• Impulse

The V&V report will assure the accuracy of:

• The Fathom, Arrow or Impulse database files for:
  • Flow and pressure calculations, using pipe and junction features (Each junction type will be checked against manual calculations for the different user options provided by either Fathom or Arrow.)
  • Steam and water properties (density, viscosity, vapor pressure)
  • Pipe sizes (diameters, thickness)
  • Pipe roughness
  • Fitting loss data
• Heat transfer (fluid and pipe wall temperatures, heat rate, heat flux, etc.) calculations from user supplied thermo-physical data (i.e. thermal conductivity of pipe and insulation data, etc.)
• GSC module results for the goal and variable options provided by either Fathom or Arrow (optional for GSC modules only)
• XTS module results for the time triggering scenarios provided by Fathom (optional for XTS module only)
• Any limitations of the software identified as a result of the V&V

Below are the most recent releases that have been verified and validated.

• Please note: The latest validated releases will not necessarily be the most recent general release of Fathom, Arrow or Impulse.
