OBTAINING ISOTOPICALLY MODIFIED MOLYBDENUM IN ORDINARY AND DOUBLE CASCADES OF GAS CENTRIFUGES

A method has been developed for calculating the parameters of cascades with an assigned number of gas centrifuges in the stages whose separation factors depend on their feed fl ow and the fl ow cut. Based on this method, a computational experiment was conducted on separation of molybdenum hexafl uoride and concentration of ^92,98,100Mo isotopes with a low neutron-capture cross section in the outgoing streams of ordinary and double cascades. The author has determined the features of obtaining isotopically modifi ed molybdenum from waste and selected products of such cascades, which is suitable for creating reactor materials with improved thermophysical characteristics. The infl uence of the factors associated with the feed fl ow of cascades and the types of stages, as far as the number of gas centrifuges is concerned, has been studied. It has been shown that the feed fl ows and the separation factors of the stages of gas-centrifuge cascades differ signifi cantly from rectangular and rectangularpartitioned cascades.
