Removal of Tritium and Other Radionuclides from Mixed Liquid Waste

Kinectrics USEP process is a Canadian solution for disposal of problematic mixed liquid waste

The Kinectrics Universal Separation Process (USEP) was developed as an application to remove tritium and other radionuclides from highly-tritiated mixed liquid waste.

Process features and benefits:: 

  • Removes all radionuclides in the mixed waste to below unconditional clearance limits permitting its disposal as conventional hazardous waste.
  • Removes tritium from the hydrocarbon backbone.
  • Avoids the need for cross-border shipments thus significantly reducing the complexity and cost for waste disposal.
  • Environmentally friendly and ALARA compliant with no tritium release to the environment.
  • Successfully demonstrated on several drums of highly tritiated oily mixed waste from a Canadian nuclear facility.

Key process steps:

      1. Removal of bulk tritium via dehydration
      2. Waste treatment using small quantities of commercially-available chemicals / sorbents followed by filtration
      3. Final disposal of processed water
      4. Small quantity of secondary waste disposed as solidified radioactive waste at a licensed nuclear facility
