The paper describes the results from studies into the role of water in the formation of associates from nanosized complexes of uranium in a supercritical carbon dioxide (SC CO2) medium. It has been demonstrated experimentally that water in the SC CO2 exists in the form of microdrops. It is found that at a pressure of 10 MPa and a temperature of 40°C the UO2(NO3)2∙2(C4H9O)3PO complex may take on hydrophilic properties. The conclusion is made that in that event the mentioned complex would concentr
