As the technique of the recovering Pd, Se, Cs and Zr of the elements containing a long half-life nuclide from high-level liquid waste, electrolytic, adsorption and solvent extraction methods are selected, and the separation recovery process is studied.
The concept of facility using these technique is reported.
