FATE 2.0™ is used for design, off-normal, and accident analyses of nuclear and chemical facilities. FATE 2.0™ is the successor to computer codes used extensively for design and safety analyses for U.S. Department of Energy projects at the Hanford site and elsewhere (HADCRT for Tank Farms, Waste Treatment Plant, WESF, PFP; HANSF MCO and HANSF Sludge for Spent Nuclear Fuel and sludge, T Plant).

New major models introduced with FATE 2.0™ are:

• Flammability and combustion of gases, vapors, and aerosols: Any input compound may participate; examples include solvent vapors, hydrogen, and U metal or hydride aerosols.
• Entrainment of deposits to form aerosols: Powder, liquid, and sludge waste may be entrained by combustion or flow.
• Thermal radiation networks: View factor models and automatic network balancing.
• Event-oriented simulation: Intervention criteria and actions for scenario evolution.
• Fire model (limited distribution): Define burn rate and yields; Smoky layer model.
  

General capabilities of FATE 2.0™ include:

• Multiple-compartment thermodynamics and general species: Facility rooms have separate pressure, temperature, and composition; Compound property libraries are input; Tracking of condensed, gaseous, and aerosol species.
• Facility nodalization and flow: Compartments are connected in arbitrary topology by flow paths; Flows are pressure-driven, density-driven counter-current, and diffusional.
• Aerosol behavior: Aerosol coagulation, sedimentation, transport with flow; Deposition on bends and filters; Deposition by condensation; Aerosol formation by boiling and fog.
• Heat transfer: Convection of liquids and gases to structures with internal temperature distributions; Linking for 2D and 3D heat transfer; Condensation.
• Sources and time-dependent conditions. Prescribe liquid, gas, and aerosol source histories and environmental conditions with time.
• Nuclear fuel and sludge models including chemical reactions.
  

FATE is created and maintained under the FAI Quality Assurance Program (10CFR50 App. B & ISO 9001 compliant). For additional information please contact us.
