UOP IONSIVTM Selective Media: Market-leading nuclear waste remediation products

IONSIV Selective Media are microporous, inorganic, crystalline adsorbents that exhibit high selectivity and capacity for radionuclides in the presence of high concentrations of competing cations. These adsorbents retain their physical integrity and selectivity over a broad pH range in the presence of high levels of ionizing radiation and exhibit a high resistance to attrition.

IONSIV Selective Media have been used in the nuclear industry for more than 40 years and are currently being used to remove nuclear fission products from water at Japan’s Fukushima Daiichi nuclear power plant.

UOP IONSIV Selective Media offer superior performance:

  • High Capacity and Selectivity
  • Low Final Waste Volumes
  • Single Use Media
  • High Radiation Stability
  • Superior Chemical Stability
  • Superior Mechanical Stability

UOP offers a portfolio of Selective Media , consisting of alumino silicates (zeolites) and crystalline silicotitanates, which allow you to tailor a solution for your specific needs.

Ideally suited for the following applications:

  • Removal of cesium and strontium from radwaste streams in commercial power plants
  • Removal of cesium and strontium from radwaste streams in decommissioning / decontamination projects
  • Removal of cesium and strontium from nuclear reprocessing waste alkaline supernatant
  • Removal of cesium from evaporator overheads
  • Removal of cesium and strontium from nuclear fuel storage pool water
