Nuclear Verification and Validation

For AFT Fathom, Fathom GSC Module, and Fathom XTS Module

In cooperation with Applied Flow Technology, Archon Engineering has developed a Nuclear Verification and Validation package to enable the use of AFT Fathom software in safety related applications in the nuclear industry. The package assists with the performance of a Commercial Grade Dedication process.

Quality Assurance

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

Package Details

The V&V report will assure the accuracy of:

  • Fathom's database file for:
    • Flow and pressure calculations, using Fathom's pipe and junction features (Each junction type will be checked against manual calculations for the different user options provided by Fathom.)
    • 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 Fathom (optional for GSC module 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

Software Downloads

  • The link below is to the most recent AFT Fathom release that has been verified and validated.
  • The latest validated release will not necessarily be the most recent general release of AFT Fathom.
  • It is for the AFT Fathom software only - the Commercial Grade Dedication V&V package must be purchased directly from Archon Engineering.
