On November 25, KEPCO E&C signed a Cooperation Agreement(CA) with Japan’s public interest incorporated foundation, Radwaste and Decommissioning Center (RANDEC) for a demonstration project on decontamination of radiocesium-contaminated cinder (the Project). 

The agreement is aimed at undertaking the Project in Japan to commercialize decontamination facilities, and promoting optimal operation of the commercialized facilities. Under the agreement, KEPCO E&C is to manufacture and install decontamination facilities and to provide technical support for operation and maintenance of the facilities. RANDEC is tasked with various activities as follows: to provide land and buildings for a demonstration test, to transport radiocesium-contaminated cinder, to dispose of radioactive waste, and to assess decontamination facilities performance.

“Decontamination technology of radiocesium-contaminated cinder” (the Technology) makes it possible to separate radiocesium from contaminated cinder, to remove it through coagulation process, and ultimately to dispose of and/or manage the cinder as a safe general waste. 

KEPCO E&C developed the Technology building on decontamination technology of radioactive waste, and achieved successful decontamination at 85% through a joint demonstration proejct with RANDEC in Japan in Nov 2013.

KEPCO E&C, based on its ever-evolving technology, successfully developed facilities able to dipose of radiocesium-contaminated cinder of as much as 10 tons/day, with the aim of exporting the facilities starting from 2015. A comprehensive performance test will be administered in Fukushima, Japan from 2015 to verify the performance of  facilities and make the facilities improve to enter the market.

After the Fukushima nuclear accident, safe disposal of over 100,000 ton-designated waste cinder contaminated by radiocesium of more than 8,000Bq/Kg has been a pending issue in Japan.
