Kurion has received a contract from Tokyo Electric Power (TEPCO) for the supply of a first-of-its-kind, at-tank mobile system to remove strontium from tank water at the damaged Fukushima Daiichi nuclear power plant.
Under the contract, Kurion will provide its Kurion Mobile Processing System (KMPS), which will be moved around the site and placed beside tank groups.
The system will allow TEPCO to reduce strontium (Sr) from the hundreds of tanks on-site that contain approximately 400,000kg of water, a volume that is expanding at 400t per day.
A different proprietary, inorganic and easily vitrified ion-exchange media will be used by Kurion for KMPS to separate strontium from competing, lower-risk contaminants also present in the water.
Kurion founder and president John Raymont said Kurion and TEPCO have been working since 2011 to address cesium, which presented the greatest immediate threat to human safety and the environment.
"So, reducing strontium in tank water stored on-site will significantly improve worker safety and reduces the risk to the surrounding environment," Raymont said.

The first set of equipment has already been delivered by Kurion to the plant’s staging area for inspection while the remaining equipment is slated to be delivered in the coming weeks.
Kurion and TEPCO will work together to improve operations and performance of the system, which is expected to be operational this summer.
Kurion CEO Bill Gallo said that Kurion will help TEPCO and the Japanese people in finding a solution for the waste at the Fukushima Daiichi site
"Since Kurion started working with TEPCO in 2011, we have grown our team by more than tenfold and expanded our technologies and services to provide the scale and breadth of solutions needed for Fukushima and other nuclear and hazardous waste challenges worldwide," Gallo said.
