TREATMENT METHOD OF CORIUM

Document Type and Number:

Japanese Patent JP2013088117

Kind Code:

A

Abstract:

To provide a treatment method of a corium with which radioactive substances, Fe, Zr are collected separately, respectively.

A treatment method of a corium includes the steps of loading a corium on an anode (S11) and causing a cathode to electrolytically deposit a metal Zr (S12), causing an exchanged cathode to electrolytically deposit a metal Fe (S13), bubbling first gas to increase oxidizability of an atmosphere of the anode (S14), causing the exchanged cathode to electrolytically deposit a U oxide (S15), bubbling second gas to further increase oxidizability of the atmosphere of the anode (S16), causing the exchanged cathode to electrolytically deposit a mixture of the U oxide and a Pu oxide (S17), collecting a residue which is residual in the anode (S18), and collecting a fission product contained in an electrolytic bath 12 (S19).
