The immobilization of Three-Mile Island core debris in iron-enriched basalt (IEB), a fused-cast nuclear waste form, was considered. The amount of zirconium clad UO/sub 2/ fuel assemblies that can be dissolved in IEB using the Zr to UO/sub 2/ ratio present in the core was bracketed between 25 and 30% at 1500/sup 0/C. The factors controlling the rate of dissolution of fuel pellets and Inconel, a structural component of the core, were investigated. Since the UO/sub 2/ dissolved in IEB could be a valuable resource in the future, the recovery of uranium from IEB using conventional ore-dressing and leaching techniques was assessed.
