Chornobyl NPP signed an Agreement with Finnish company "Fortum Power and Heat Oy" regarding joint pilot tests on radioactively contaminated water (RCW) treatment at Chornobyl NPP.

Fortum Company (Finland) is a developer of selective ion exchange materials, namely sorbents series CsTreat®, CoTreat® and SrTreat® with proprietary right and confidential composition.

Within the framework of the tests it is planned to purify radioactively contaminated water from radionuclides in a pilot plant using ion exchange materials developed by Fortum, to analyze the initial and purified media, and to prepare a report with the results obtained.

Before the Agreement signing in 2018 - 2019, the parties performed relevant laboratory tests. Their results confirmed the feasibility of these sorbents additional testing in a pilot plant. Besides, the pilot test program will be complemented with RCW pre-treatment and separation of organic compounds by oxidation.

Pilot tests will allow make a decision regarding the possibility to use this technology to process accumulated Chornobyl RCW, which volume is more than 20 thousand cubic meters.
