This study considered a conceptual process system for an ambitious treatment of the cladding tube waste, i.e. hull wastes, in order to purpose both the remarkable volume reduction and the recycle use of Zr source of the waste. The conceptual system consisted of chlorination, oxidation and metallization. The main process was the chlorination of the hull waste mainly composed with Zr alloy, and the volatile ZrCl4 was effectively separated and recovered from other elements in the waste. For the effective reduction of total waste volume, the oxidation treatment for the residue containing U, Pu ,Ni, Cr, Co, Cs, etc. was added in the system to recover oxides of U, Pu and TRU, additionally to feed them into the reprocessing process. Moreover, this treatment could carry out the fractional recovery between a-decay nuclides and βy-decay nuclides. The performance of chlorination and oxidation was experimentally examined with the thermodynamic calculation. A direct metallization of ZrCl4 to Zr metal was investigated with literature and a capability of electrodeposition in the molten salt technology was estimated for the recycle use of Zr.
