Abstract

FIELD: nuclear engineering; production of molybdenum-99 fission radionuclides for diagnosing many diseases. SUBSTANCE: method involves irradiation of fissionable material solution and separation of desired nuclides from circulating solution of fissionable material. Two operations may be time-shifted: irradiation of fissionable material solution and separation of desired nuclides from it. Production process may be maintained either continuously or periodically; volume of fissionable material solution may exceed critical value conditioned by chain reaction of nuclear fission. Aqueous salts of uranium, such as uranyl sulfate, may be used as fissionable material. EFFECT: improved efficiency of fission nuclides production. 6 cl, 1 dwg

Изобретение относится к ядерной технологии и может быть использовано в производстве осколочного радионуклида молибдена-99 для диагностики многих заболеваний. Цель: повышение выхода конечного продукта на единицу используемого делящегося материала и уменьшение удельного объема радиоактивных отходов. Сущность изобретения: в способе производства осколочных нуклидов подвергают облучению раствор делящегося материала, а выделение необходимых нуклидов ведут из циркулирующего раствора делящегося материала. При этом возможно совмещение по времени двух операций: облучения раствора с делящимся материалом и выделения из него необходимых нуклидов. Процесс производства может поддерживаться как непрерывно, так и периодически, объем раствора с делящимся материалом может превышать критический по условиям цепной реакции деления ядер. В качестве делящегося материала возможно использование водных солей урана, например уранилсульфата. Положительный эффект заключается в повышении эффективности производства осколочных нуклидов.The invention relates to nuclear technology and can be used in the manufacture of fragmentation radionuclide molybdenum-99 for the diagnosis of many diseases. Purpose: increasing the yield of the final product per unit of fissile material used and reducing the specific volume of radioactive waste. The inventive method for the production of fragmentation nuclides is subjected to irradiation of a solution of fissile material, and the selection of the necessary nuclides is carried out from a circulating solution of fissile material. Moreover, it is possible to combine two operations in time: irradiating the solution with fissile material and isolating the necessary nuclides from it. The production process can be supported both continuously and periodically, the volume of the solution with fissile material can exceed the critical one according to the conditions of the chain reaction of nuclear fission. As fissile material, it is possible to use aqueous salts of uranium, for example, uranyl sulfate. The positive effect is to increase the production efficiency of fragmentation nuclides.
