Chlorination of UO$$_{2}$$ and (U,Zr)O$$_{2}$$ solid solution using MoCl$$_{5}$$

Sato, Takumi; Shibata, Hiroki; Hayashi, Hirokazu; Takano, Masahide; Kurata, Masaki

Journal of Nuclear Science and Technology, 52(10), p.1253 - 1258, 2015/10

In order to explore the applicability of the chlorination by MoCl$$_{5}$$ as a potential pretreatment technique for waste treatment of fuel debris by pyrochemical methods, chlorination experiments of UO$$_{2}$$ and (U$$_{0.5}$$Zr$$_{0.5}$$)O$$_{2}$$ simulated fuel debris were carried out in two steps: the first one is a chlorination reaction by homogeneous heating, the second one is a volatilization of molybdenum by-product by heating under temperature gradient condition. Most of UO$$_{2}$$ and (U$$_{0.5}$$Zr$$_{0.5}$$)O$$_{2}$$ powder were converted to UCl$$_{4}$$ or UCl$$_{4}$$ and ZrCl$$_{4}$$ mixture at 573 K, respectively. In the case of (U$$_{0.5}$$Zr$$_{0.5}$$)O$$_{2}$$sintered particle, most of sample was converted to the chlorides because the products evaporated and be separated from sample surface at 773 K, while only the surface of the sample disk was converted to the chlorides at 573 and 673 K. Most of molybdenum by-product and ZrCl$$_{4}$$ were separated from UCl$$_{4}$$ by volatilization at 573 K.
