Title: Reusable molds for casting U-Zr alloys

Abstract

Refractory oxides, carbides, nitrides and sulfides were examined as mold coating materials for use in casting nuclear fuel. The molds require excellent high temperature chemical and mechanical stability combined with reasonable room temperature ductility to allow for fuel removal. Coatings were applied onto quartz and refractory metal coupons using various techniques. Sessile drop tests employing molten U-10%Zr (by weight) at 1550{degrees}C were used to characterize coating performance. Results indicate that NbC, TiN, and Y{sub 2}O{sub 3} were non-wetting with U-10%Zr. However, only the Y{sub 2}O{sub 3} coating completely prevented adhesion of the fuel. The paper describes coating methods and details of the sessile drop experiments.
