Title (EN) PROCESS FOR PRODUCING A FRACTION CONTAINING RADIOISOTOPES OF IODINE, IN PARTICULAR OF PURE I-131, AND FRACTION CONTAINING THE RADIOISOTOPES OF IODINE, IN PARTICULAR OF I-131
(FR) PROCEDE DE PRODUCTION D'UNE FRACTION CONTENANT DES RADIO-ISOTOPES DE L'IODE, EN PARTICULIER D'I-131 PUR, ET FRACTION CONTENANT LES RADIO-ISOTOPES DE L'IODE, EN PARTICULIER D'I-131
Abstract: front page image
(EN) The present invention relates to a process for producing a fraction containing radioisotopes of pure iodine, in particular of pure l-131, comprising the steps of basic dissolving of highly enriched uranium targets with the obtaining of a slurry, filtering said slurry in order to isolate a basic solution of molybdate and iodine salts, in particular l-131 salts, acidifying said basic solution with formation of an acid solution of molybdenum salts and release of a fraction of radioisotopes of iodine, in particular of l-131, in gaseous form with a view to the recovery thereof, purifying said fraction of iodine radioisotopes to form a fraction containing radioisotopes of pure iodine, characterized in that the process comprises, before said step of acidification of the basic solution, a cooling of the basic solution to a temperature below or equal to 60°C, preferably below or equal to 55°C, more particularly below or equal to 50°C.
(FR) La présente invention concerne un procédé de production d'une fraction contenant des radio-isotopes de l'iode pur, en particulier d'l-131, pur comprenant les étapes de dissolution basique de cibles d'uranium hautement enrichi avec obtention d'une bouillie, filtration de ladite bouillie afin d'isoler une solution basique de molybdate et de sels d'iode, en particulier d'l-131, acidification de ladite solution basique avec formation d'une solution acide de sels de molybdène et dégagement d'une fraction de radio-isotopes de l'iode, en particulier d'l-131, sous forme gazeuse en vue de sa récupération, purification de ladite fraction de radio-isotopes de l'iode pour former une fraction contenant des radio-isotopes de l'iode pur, caractérisé en ce que le procédé comprend, avant ladite étape d'acidification de la solution basique, un refroidissement de la solution basique jusqu'à une température inférieure ou égale à 60°C, de préférence inférieure ou égale à 55°C, plus particulièrement inférieure ou égale à 50°C.
