Nuclear Verification and Validation

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

In cooperation with Applied Flow Technology, Archon Engineering has developed a Nuclear Verification and Validation package (V&V) to enable the use of AFT Fathom software in safety related applications in the nuclear industry.

The V&V package assists with the performance of a Commercial Grade Dedication (CGD) process on AFT Fathom and its Goal Seek and Control (GSC) and Extended Time Simulation (XTS) modules.

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. Archon has been audited and placed on the Nuclear Procurement Issues Committee (NUPIC) approved suppliers list. NUPIC members include all U.S. nuclear utilities and several international members.

Package Details

The V&V report will assure the accuracy of:

  • Fathom's database file for:
    • - Steam and water properties (density, viscosity, vapor pressure)
    - Pipe sizes (diameters, thickness)
    - Pipe roughness
    - Fitting loss data
  • 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.)
  • 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

Contents

  • V&V documentation:
  • Verification Test Plan, outlining the tests used to verify Fathom results
  • Verification Test Report, comparing Fathom program results to hand calculations
  • Identification of the software verified by file version, size and date
  • Selected sample models with output
  • Subscription instructions for AFT's error notification program

Pricing

The Nuclear Verification & Validation package is sold by Archon Engineering, P.C. For pricing information or for more detail about the V&V package please visit Archon Engineering.

Software Downloads

These are the installation packages that have been verified and validated. This is only the Fathom software - the Commercial Grade Dedication V&V package can be purchased from Archon. Note that this software release may not be the latest available since not all releases have been verified and validated for nuclear use.
