Abstract

A description of the installation for the supercritical fluid extraction of uranium complexes in the carbon dioxide medium, as well as instrumentation for the analysis of the test materials are presented. A method of selection of granites, which are used to modeling the material of technogen dumps of nuclear power or nuclear fuel of nuclear reactors are described. A description of the method of sample preparation and analysis of extracts on maintenance of the uranium are presented. On the example of the different kinds of granites with elevated content of the uranium it is shown that the methods of sampling and sample preparation of the starting material can be used for modeling of supercritical fluid extraction with carbon dioxide complexes of uranium  from materials of nuclear power.
