ABSTRACT
Since 1975,
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.
