FATE (Facility Flow, Aerosol, Thermal, and Explosion) is a flexible, fast-running code developed and maintained by Fauske and Associates under ASME NQA-1 compliant QA program.

FATE is a versatile software, and has capabilities to model heat and mass transfer, fluid behavior, and aerosol behavior in a variety of applications as applicable to nuclear, chemical and hydrocarbon and manufacturing industries.

FATE™'s phenomenological capabilities include:

  • Multiple-compartment representation, either well-mixed or stratified
  • Generalized chemical species via property correlations
  • Arbitrary flow path network
  • Pressure-driven, counter-current, and diffusion gas flows
  • Transport of gases and aerosols between compartments
  • Vapor-aerosol equilibrium
  • Entrainment of aerosol from liquid and deposited particulate
  • Deposition of aerosols via gravitational sedimentation, impaction, and so on
  • Combustion, and detonation
  • Heat transfer and condensation on structures
  • Multidimensional heat conduction in structures
  • Heat and mass transfer between liquid pools and gas space and submerged structures
  • Special-purpose models for oxidation and Wigner energy release from graphite
  • Special-purpose models for processing of uranium metal fuel and fuel sludge

FATE allows users to produce models of common components such as heat exchangers, pumps, fans, filter trains, valves, dampers, blow-out panels, downcomer vents and rupture disks. Additionally, operator actions and equipment trip- and setpoints can be modeled with relative ease.

Typical outputs provided by FATE™ include:

  • Gas temperature
  • Pressure
  • Liquid temperature
  • Liquid elevation
  • Mass of liquid
  • Thermophysical properties
  • Gas composition in terms of mole fractions
  • Gas composition in terms of masses
  • Relative humidity of each region
  • Aerosol masses
  • Rates-of-change of gas and aerosol

FATE™ applications:

General Industrial and Commercial and Public Safety Applications

  • Analysis of a Diesel Generator room heat build up during a loss of ventilation event was analyzed using a FATE model.
  • Analyzing the transient behavior of facilities during normal and off-normal conditions is applied to the problem of SARS-CoV-2 virus transmission in single-and multi-room facilities. Subject to the justifiable assumptions of non-interacting virus droplets, room-wide spatially homogeneous virus droplet aerosols and droplet sedimentation in accordance with Stokes law; the FATE™ code tracks the virus aerosol from a human source through a facility with a practical ventilation system which reconditions, filters, and recycles the air. The results show that infection risk can be reduced by 50 percent for increased facility airflow, 70 percent for increased airflow and the inclusion of a HEPA filter on recirculated ventilation air, and nearly 90 percent for increased airflow, inclusion of a HEPA filter, and wearing a mask. These results clearly indicate that there are operational changes and engineering measures which can reduce the potential infection risk in multi-room facilities.

Chemical Industry Applications

  • Transient model of HCl gas release in a vessel and piping system.
  • A mechanistic model of organic-nitrate reactions initiated in hypothetically reactive waste in underground storage tanks. A thermal-hydraulic assessment of tank transient pressure and temperature to yield flows of gases to the environment, a release model to predict vaporization of volatile materials from reacted waste, and an aerosol transport and deposition model to provide the source term to the environment.

Minerals and Metals Industry Applications

  • Gas generation and flow were analyzed for an ingot casting facility being constructed in the US. During the ingot producing process, occasionally a break in the mold will develop, allowing the molten metal to spill out of the hardened ingot into the casting pit, producing hydrogen through a reaction of water with lithium and aluminum.

Nuclear Industry Applications

  • Evaluated the risk from flammable gas accumulation in the buildings attached external to the containment by modeling the transport and distribution of leaked flammable gas (hydrogen and carbon monoxide) in the penetration buildings.
  • The dry cask storage (DCS) of spent nuclear fuel assemblies was analyzed for steady-state thermal behavior in an isolated loss-of-flow condition. The thermal analysis must assure that the peak cladding temperature remains below the regulatory limit for the dehumidification process.
  • Thermal response and hydrogen gas generation are examined in the Fuel Transfer System (FTS) for fuel transfer.
  • The transient and severe accident analysis capability of the SAS4A/SASSYS-1 code developed by Argonne National Laboratory is coupled with the radionuclide transport analysis capability of the FATE code to predict radionuclide release from a broad spectrum of accidents that can be postulated to occur at liquid metal cooled reactor facilities.
  • Hydrogen risk during the steam generator wet layup additive process was analyzed. The secondary side of the steam generator and piping leading up to the automatic relief valves were modeled using FATE.
  • Hydrogen accumulation in the AP1000 auxiliary building and primary containment building was analyzed in the event of a break in the chemical and volume control system (CVS) hydrogen injection line.
