Waste Management, Decontamination & Decommissioning (D&D) Process Engineering

BackgroundWaste Technology Flow Chart

Fauske & Associates, LLC (FAI) provides technical expertise and program guidance for the storage, processing and disposal of nuclear, chemical and defense waste and for process and safety analysis to support Decontamination & Decommissioning (D&D) of nuclear and hazardous material facilities.  Our three product areas for waste technology and D&D are (1) Process and safety models and analyses (2) Experimental facilities for hazard quantification and (3) The FAI developed and maintained FATETM software.  FATETM is used for process design and safety evaluations related to waste technology, process engineering and safety and decommissioning and dismantling.  It can consider engineering process components as well as facility design.

1) PROCESS AND SAFETY MODELING AND ANALYSES

  • FATETM software for process and facility design and safety calculations
  • Facility flow, heat transfer and toxic/radiological materials transport
  • Chemical and thermal behavior during waste processing, shipping and storage
  • Flammability gases and vapors/combustibility of dusts
  • Facility fire analysis including toxic/radiological effects
  • Chemical reaction propagation limits, including pyrophoricity
  • Chemical reaction rates, pressurization and radiolysis
  • Aerosol generation, transport, deposition and removal
  • Facility emissions and source terms for processes, accidents and Decontamination & Decommissioning (D&D)

2) EXPERIMENTAL FACILITIES FOR HAZARD QUANTIFICATION

3) FATE™ SOFTWARE APPLICATIONS TO NUMEROUS FACILITIES AND PROCESSES INCLUDING

  • Vacuum drying of metallic uranium particles from spent nuclear fuel
  • Shipping and storage of uranium-metal bearing spent fuel sludge including detailed container design
  • High temperature passivation of uranium-metal bearing spent fuel sludge
  • Vacuum drying of 2000 metric tons metallic spent nuclear fuel
  • Vitrification plant waste tank and ventilation system pressure and flow
  • Mixed oxide (MOX) facility fire and source term analysis including soot loading
  • Dry storage of Strontium/Cesium salt capsules
  • Storage tank hydrogen explosion and source term
  • Underground storage tank solvent vapor explosion and source term
  • Storage tank thermal response to loss of cooling
  • Nuclear power plant detailed fire modeling

BENEFITS OF FATE™ SOFTWARE

Using FATETM software, FAI can calculate temperatures, pressures, flow rates and compositions for fluids, gases and structures associated with Fate Softwarewaste management process Decontamination & Decommissioning (D&D).  It is uniquely suited to nuclear facility operations because it combines models for fluid flow and heat transfer with models for aerosol transport and deposition, explosions and fire.  FATETM has been applied to dozens of United States Department of Energy (DOE) and commercial nuclear applications and its predecessor code was awarded a DOE Silver Award for Technology Innovation at Hanford.
