ALL-RUSSIAN RESEARCH INSTITUTE OF CHEMICAL TECHNOLOGY IN PROCESSING URANIUM MINERALS DEVELOPMENTS AND INDUSTRIAL IMPLEMENTATION IN CIS COUNTRIES

摘要

The All-Russian Research Institute of Chemical Technology (ARRICT) is a leading scientific organization in mining and processing atomic energy industries providing elaboration and industrial implementation of technologies. The specifics of chemical/technological processing of uranium ores into nuclear fuel depend on the composition of the starting material and its properties. The uranium ores belong to extensively disseminated mineral species with the uranium content varying within the range of tenths and hundredths of one per cent. Therefore the chemical/technological uranium processing schemes should be developed with the account of the initial material composition and peculiarities, the uranium compounds form and the required purification degree of nuclear fuel.
