ABSTRACT OF THE DISCLOSURE Method of freeing from radioactive corrosion products and from conditioning substances stemming from the coolant loop of a nuclear reactor, ion exhanger resins spent in the operation of the reactor includes thoroughly rinsing the resin with deionate so as to release suspended radioactive substances from the resins, separating the released suspended radioactive sub- stances in a mechanical filter, rinsing with diluted mineral acid the resin previously rinsed with deionate so as to release radioactive cations and anions therefrom, adsorbing the cations and anions in an adsorber substance fixed on an inorganic carrier, and separating the conditioning substances from the mineral acid with which the resins have been rinsed and forming chemical compounds therewith for reuse.
