Abstract
The possibility of flux fabrication for processing metallurgical radioactive wastes by melting the components into a slag agglomerate aimed at returning fissionable materials to a nuclear fuel cycle is shown. The proposed compositions contain no components used in nonferrous and ferrous metallurgy, namely, silica, fluorides, and boron compounds. Fluxes based on the systems Al2O3–MnO, Al2O3–MnO–Na2O, Al2O3–MnO–CaO, and Al2O3–MgO–CaO–Fe2O3 are synthesized by cold crucible induction melting. Their thermochemical properties and phase compositions are studied.
