Management of Radioactively Contaminated Water at the Shelter Object of Chernobyl NPP

In this paper decryptsand analyzedresults of radioactively contaminated water from the “Shelter” object in the period from 1998 to 2022 years witch was pumped out. A search was made for information on the sources of radioactive water and the amount of radioactive water pumped out of the volume of the “Shelter” object and the New Safe Confinement. The volumes and activity content of radioactively contaminated water that were pumped and collected to temporary storage in the Chornobyl NPP liquid radioactive waste storage facility were analyzed. A regression and correlation analysis was carried out between the indicators of the arrival of water solutions and the volumes of radioactive water pumped out. A strong connection (according to the Chaddock scale) between atmospheric precipitation and pumping out of hazardous waste was revealed. The main source of radioactive water, before the construction and installation in the project position New Safe Confinement was atmospheric precipitation, after that it is dust-fixing mixtures. However, their volumes are insignificant and have been decreasing every year since 2013.
