The object of the present invention is a method for recirculating a reprocessing effluent comprising chloride ions from an ion exchange resin comprising the following steps: (ii) selecting fractions A, B, and optionally B′, directly stemming from a reprocessing effluent comprising chloride ions or after one or several steps for modifying the chloride ion concentration, having concentrations of chloride ions (g/l) of respectively (a), (b) and (b′)>0 g/l, with (a)>(b); (iii) transferring by electrodialysis the chloride ions from the fraction B to fraction A for obtaining a fraction C having a chloride ion concentration (c) greater than (a); or (iv) transferring by electrodialysis the chloride ions from fraction B to fraction B′, in order to obtain a fraction B″ having a concentration of chloride ions (b″) greater than (b′) and then mixing the fractions B″ and A in order to obtain a fraction C having a chloride ion concentration (c) greater than (a).
