Zircaloy Conversion Process

The Zircaloy Conversion Process (24, 25, 26) is a concept whereby one waste stream, Zircaloy fuel hulls, can be utilized in the stabilization of a second waste stream. The process flowsheet which is conceptual in nature, details the steps required to convert the fuel hulls to sodium zirconate to be used in the solidification of liquid high level waste. [Pg.144]

The work on hi level waste solidification has led to applications of the same materials to other areas of waste management. These include decontamination of defense wastes currently in tank storage at Richland, WA, selective separation of Cs for beneficial uses, and development of a process flowsheet for conversion of Zircaloy fuel cladding hulls to sodium zirconate for use in waste stabilization. Each is briefly described below. [Pg.144]

Methods that have been proposed for chemical removal of zircaloy cladding in nonaqueous processing of spent fuel include conversion to gaseous ZrCL by reaction with HCl above 350°C or solution in molten zinc, which dissolves 10 a/o (atom percent) zirconium at 900°C. [Pg.323]
