The behavior of melts in the uranium oxide-silicon dioxide system is experimentally investigated in air upon induction melting in a “cold crucible.” The existence of the two-phase liquid region in this system is confirmed. It is demonstrated that the melts absorb oxygen from air, which leads to crystallization of the UO2.25 compound upon cooling. In the case of considerable internal heat release, sharp cooling of the melt surface results in the liberation of gas, which brings about bulging and… Expand
