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.
