Unidad de Actividad Materiales y Combustibles Nucleares - CAE – CNEA


The Argentinean National Atomic Energy Commission (CNEA) is now beginning to produce fission 99Mo (parent of the radionuclide 99mTc, widely used in medicine) by irradiation of targets containing 20% enriched uranium. The reduction from the previously employed enrichment of 90% implies an increase in the mass of uranium necessary to produce the same 99Mo activity. This, and the fact that the irradiated uranium has a very low burn-up, led to the decision of studying the feasibility of a method for the recovery (and later reuse) of the irradiated uranium, in order to reduce purchase and post-irradiation storage costs. This task is part of a project for to improving several aspects of the 99Mo production process (including the recovery and purification of other valuable fission products, such as 137Cs, 90Sr and 133Xe).
