摘要：A process for the recovery of a radioisotope from a waste resin of a nuclearpower plant comprises the steps of: a) treating a waste resin loaded with at least one
radioisotope with an organic acid or alkaline compound to release the at least oneradioisotope and to obtain a process solution containing the at least one radioisotope; b)separating the at least one radioisotope from the process solution through a reactionspecific to the radioisotope so as to obtain a treated process solution depleted of the atleast one radioisotope, wherein said depleted process solution comprises the organicacid or alkaline compound and optionally a non-reacted radioisotope; c) reacting theorganic acid or alkaline compound in the depleted process solution from step b) bythermal and/or photochemical oxidation to form gaseous reaction products; and d)reloading the waste resin with the reacted process solution from step c) to bind the non-reacted radioisotope on the waste resin. Further, an apparatus is provided to carry outthe above method.
