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.


In July 2020,
On September 17, Chornobyl NPP agreed with the State Nuclear Regulatory Inspectorate of Ukraine the required documentation to start a pilot operation of the facility for materials release from regulatory control.
Within the framework of hot tests commenced on September 10, 2020, at the new Interim Spent Fuel Storage Facility of Chornobyl NPP, all the operations related to the first real spent fuel assembly (SFA) preparation for storage have been successfully completed.
