Verified For Unique Project Needs
Kurion Conducts Extensive Studies At Its Licensed Radioactive Laboratory In Richland, Washington, To Select The Most Effective Media For Each Project
Technology Proven over Centuries Kurion’s Ion Specific Media builds upon technology dating back to the 19th century and proven effective for environmentally remediation at Three Mile Island and Fukushima Daiichi
Kurion Takes On Cesium At Fukushima Daiichi Kurion’s Ion Specific Media Is Credited With Capturing 70% Of The Radioactivity Removed From Contaminated Water Within The First Nine Months Of Operation
Kurion’s Ion Specific Media captures specific ions from contaminated water efficiently and economically.
Kurion’s media and treatment systems have shown their effectiveness at Fukushima Daiichi, where they are used to remove cesium and strontium. These systems comprise two of the “seven samurai” that are cleaning contaminated water at the site.
Based on ion exchange – a natural phenomenon that has been harnessed by scientists and engineers for over 150 years – Kurion’s Ion Specific Media builds upon technologies used in the cleanup of Three Mile Island to selectively remove ions from water.
Ion exchange plays a crucial role in protecting the environment from nuclear waste, particularly ions found in contaminated water that emit alpha, beta and gamma particles.
A Molecular Filter
The greatest threat to human health and the surrounding environment are ions and isotopes with long half-lives, such as cesium-137, strontium-90, iodine-129, and technetium-99. Kurion captures these hazards with its Ion Specific Media through an ion exchange process.
Ion separation is a key step in Kurion’s comprehensive approach to waste management. Kurion’s family of media are easily converted into glass, the most stable form for waste disposal.
How It Works
Ion exchange materials can capture ions based on both their size and charge.
Imagine a chain-link fence: The wires form a hole in which a single golf ball is perched. If a tennis ball were to hit the fence, it would displace the golf ball and stick within the links. Similarly, ions such as cesium act as the tennis ball during the ion exchange process, where they displace sodium and are captured within the exchange material.
Kurion’s media have been used to treat contaminants in many types of projects: groundwater remediation, nuclear fuel pools, and most recently, the cleanup of the Fukushima Daiichi Nuclear Power Plant.
Flexible and Efficient
Kurion offers several classes of Ion Specific Media: zeolite-based, titanosilicate-based, phosphate-based and fully synthetic specialty media for difficult projects.
Our media offer multiple advantages over alternative materials:
Kurion Ion Specific Media are available in three formats to accommodate the needs of any project:
The media are compatible with existing nuclear power plant water purification and demineralization systems.
A key component of the company’s end-to-end approach, Kurion’s family of media is inorganic and easily converted into glass through Kurion’s vitrification technologies.
