Determination of the liquidus surface in the UO2 — ZrO2 — Fe(Cr, Ni)Oi system

Determination of the liquidus surface in the UO2 — ZrO2 — Fe(Cr, Ni)Oi system Results of an experimental study of the interaction between corium melts of various compositions in the UO2 — ZrO2 — Fe(Cr, Ni)Oi system and the hard ZrO2 wall of a cold crucible upon induction heating are presented. The conditions of heating, melting, and interaction with the hard wall and the heat balance in such a crucible are considered with allowance for the special features of the behavior of two-phase melts, when the melting occurs at a temperature ranging from liquidus to solidus. The notion of the effective liquidus temperature below which the binary system behaves as a solid body and above which it behaves as a liquid is suggested. The results of the analysis show that an unknown high-temperature (Tmelt ≈ 2700 K) compound of composition close to 5UO2 · 7ZrO2 · 4Fe(Cr, Ni)Oi exists in the UO2 — ZrO, — Fe(Cr, Ni)Oi system.
