the Chilean Nuclear Energy Commission (CCHEN) is
producing in its nuclear reactor RECH-1 radioisotopes as
99mTc, 131I, 192Ir,
153Sm and others. For the last two years
CCHEN has been producing Mo-Tc generators using Canadian
fission 99Mo. The challenge is now the indigenous
fission 99Mo production from LEU foils,
thanks to an IAEA CRP supported by ANL, USA.
CCHEN has the infrastructure and qualified personnel required, who is now working in the different steps of the project that are: neutronic, thermal-hydraulic and dose rate calculations, development of the production of annular targets, chemical process of separation and purification of Mo and outfitting of the big reactor hot cell.
At the moment, the first results are the neutronic and the 99Mo activity calculations for different neutron fluxes and irradiation times (using Scale-4.4a), the design and construction of the draw die and welding assemblies to use for the target production, the preparation of synthetic solutions emulating the LEU foil dissolution and the decommissioning of the reactor hot cell to use in this project.
