Nuclear / Chemical and Radioactive Waste Safety

Chemical and Radioactive Waste Safety

Background

RadioactiveActive nuclear fuel cycle facilities and commercial nuclear power plants scheduled to be decommissioned and dismantled generate waste streams that consist of many chemical and physical forms.  During processing, packaging or storage, some waste materials have the potential to undergo chemical reactions that liberate heat and gaseous products.  Such facilities must establish operational limits and safety precautions by determining which chemical reactions could occur, how rates of reaction vary with temperature and what the nature of the reaction products will be. 

Testing & Services

Fauske & Associates, LLC (FAI) performs testing and provides calorimetry equipment to collect chemical reactive system data needed for process design and safety.  FAI services (with equipment that can be used in hot cells) encompass:FAI ARSST

  • Vent Sizing Package 2  (VSP2) for reactive system characterization, including venting and flow characteristics with measurement of heat up and pressurization rates during a process upset (100ml scale)

Both the ARSST and VSP2 are designed to simulate runaway chemical reactions so their data can be directly scaled to process conditions.

FAI VSP2FAI also supplies measurement services including: 

Expertise/Solutions

FAI was the prime contractor for the Design Institute for Emergency Relief Systems (DIERS) for the American Institute of Chemical Engineers.  In that capacity, the company’s primary role was the development of the state-of-the-art calorimetry technology and design application methodology.  More than 300 reactive system calorimetry units have been sold by FAI to companies worldwide.

In addition to offering reactive system calorimeters, FAI operates a complete world-class process safety lab with the instruments and software necessary to perform any process safety study and also has large scale and speciality testing capabilities.
