Zusammenfassung:	Process for the recovery of technetium which consists in recovering technetium in the form of a precipitate or coprecipitate by heating a solution containing technetium in the presence of a reducing agent and of an element of the platinum group. The solution containing technetium is a highly radioactive liquid waste originating from a nuclear fuel reprocessing plant. Procédé de récupération du technétium qui consiste à récupérer le technétium sous la forme d'un précipité ou d'un coprécipité en chauffant une solution contenant du technétium en présence d'un agent réducteur et d'un élément du groupe du platine. La solution contenant du technétium est un déchet liquide hautement radioactif provenant d'une installation de retraitement du combustible nucléaire.
