Presentation of the report at the 2023 RemPlex Global Summit
From November 13 to 17, the 2023 RemPlex Global Summit on Environmental Remediation, organized in cooperation with the International Atomic Energy Agency (IAEA), was held at the US Pacific Northwest National Laboratory, Richland, Washington.
The RemPlex Summit brought together participants from government, industry and research institutions to discuss environmental remediation challenges and collaboration on both proven and innovative solutions. The integration of international case studies and technical sessions, training seminars and site tours provides opportunities for networking and knowledge sharing related to the ongoing and complex environmental restoration issues facing the international community.
Scientists from the Institute for Safety Problems of Nuclear Power Plants of the NAS of Ukraine participated in the event: I. O. Kovalenko, M. I. Panasiuk, N. V. Sosonna. The following scientists also took part in the summit: M. H. Buzynnyi (SI “O.M. Marzieiev Institute for Public Health” of the NAMSU), I. P. Onyshchenko (Radioecology Center of the NAS of Ukraine), I. L. Koliabina (Institute of Geological Sciences of the NAS of Ukraine), B. Faibishenko (Lawrence Berkeley National Laboratory, USA).
Ihor Kovalenko presented the report “Radioactive Contamination of Groundwater in the Vicinity of the Destroyed 4th Unit of the Chornobyl Nuclear Power Plant”. The work was performed jointly by all the participants presented above.
The purpose of the work was to present a comprehensive description of studies of groundwater radioactive contamination around the 4th power unit of the Chornobyl NPP.
The report presents the results of a number of studies, including those conducted using the Geochemist’s Workbench Community Edition software package, which was used to analyze the Visual Modflow data, in which a model of the radio-hydroecological conditions of the area around the ChNPP was built; numerous graphs and diagrams illustrating environmental 90Sr contamination and data on the effect of various factors on 90Sr migration.
