Resumo
The use of radioisotopes in medicine is certainly one of the most important social uses
of nuclear energy. The 99mTc, generated from the 99Mo nuclear decay, is the most
suitable radionuclide for single photon emission computed tomography imaging
technique. The 99mTc is supplied as 99Mo/99mTc generators, which provide 99mTc as
the 99Mo decays. In Brazil, the generators have been imported. Currently, the world's
99Mo supplying depends on the operation of research reactors which are aged around
40 years and, therefore, are not capable of reliable operation. This situation makes the
99Mo production chain particularly vulnerable. Recent crises in the supply of 99Mo has
profoundly affected the distribution of 99Mo/99mTc generators in Brazil and
encouraged the starting of the RMB - Brazilian Multipurpose Reactor, which has as one
of the objectives to make the country independent in the production of radioactive
isotopes for medicine. The success of RMB Project will require the manufacturing
technology of irradiation targets for the 99Mo production from nuclear fission. As IPEN
in its history has been developing fuel for research reactors, and the manufacture of
irradiation targets is based on this type of technology, IPEN began developing the
technology to fabricate these targets. The manufacturing processes of two types of
targets using low enriched uranium (LEU) are being studied. The first one is based on
UAlx-Al dispersion targets, which is being used commercially in Argentina and
Australia. The second one is based on thin foils of metallic uranium, which was
developed by Indonesia with US support. This paper presents the current status of
ongoing activities at IPEN-CNEN/SP related to the development of these two types of
LEU irradiation targets for future production of 99Mo in RMB.
