Nuclear Waste Remediation
UOP IONSIVTM Ion Exchangers used for Fukushima Daiichi water clean-up
IONSIV Ion Exchangers successfully used to remove radiation from water at Japan’s Fukushima Daiichi nuclear power plant.
UOP IONSIV Ion Exchangers: Market-leading nuclear waste remediation products
IONSIV Ion Exchanger adsorbents are microporous, inorganic, crystalline cation exchangers that are proven to exhibit superior capacity, selectivity and stability over other ion exchange products.
Currently being used to remove radionuclides from water at Japan’s Fukushima Daiichi nuclear power plant, IONSIV Ion Exchangers have been used in the nuclear industry for more than 40 years.
UOP IONSIV Ion Exchangers offer superior performance:
- High Cation Exchange Capacity and Selectivity
Compared to common organic resin and inorganic ion exchangers, IONSIV Ion Exchangers exhibit high selectivity and capacity for specific radioactive cations, even when high concentrations of competing non-radioactive cations are present
- Minimizes Final Waste Forms
IONSIV Ion Exchangers’ compatibility with final waste forms, combined with high cation exchange selectivity, minimizes the quantity of final waste forms
- High Radiation Stability
Excellent retention of ion exchange capacity and superior physical integrity, even in the presence of high levels of ionizing radiation, make this product well-suited for the recovery and concentration of radioisotopes for long-term storage
- Excellent Chemical Stability
IONSIV Ion Exchangers retain their physical integrity and high ion exchange selectivity over a broad pH range, including extreme pH levels
- Superior Mechanical Stability
All IONSIV products are formulated with high resistance to attrition and dusting. They exhibit no change in volume on contact with waste solutions – eliminating the mechanical problems often associated with the swelling of organic resins
- Single-use Media
IONSIV products require no regeneration, leading to lower costs and higher reliability
We offer a portfolio of inorganic ion exchangers, consisting of alumino silicates (zeolites) and crystalline silicotitanates, allowing you to tailor a solution for your specific needs.
Typical applications include:
- Removal of cesium and strontium from radwaste streams in commercial power plants
- 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
