Selection criteria based on density and uranium capacity are presented for fuel to be used in accident-tolerant fuel rods. The optimal composition of the uranium-molybdenum alloy is proposed based on studies and experience in working on the development of uranium alloys. Two technological schemes for producing fuel pellets are considered: melting and casting. The technology of forming pellets by the powder method is also considered. The results of a study of the physical and mechanical characteristics of cast and sintered fuel pellets in confirmation of their compliance with the specified criteria are presented.
