ABSTRACT

The thread of proliferation of nucleus materials, which can be used in military purpose, has concentrated world community attention on reconversion of research reactors, who are the main users high enriched fuel, on low enriched one. The studies in this area are executed within the framework of international program RERTR under the aegis of Argonne National Laboratory and the DOE, USA. The Russian part of program is coordinated A. A. Bochvar All Russian Research Institute of Inorganic Materials (VNIINM). During the action of this program the new designs of fuel have been made on base of Uranium dioxide (UO₂-Al) and silicide (U₃Si₂-Al), and compositions U-Mo-Al, which have higher Uranium content in comparison with UAl_x alloys. The majority fuel compositions have passed testing in research reactors with broad range of Uranium density in compositions and depths of depletion. That has allowed proceeding with practical decision of the task to reduce of the enrichment [1].
