description | All fission-based 99Mo producers worldwide are required to convert their 99Mo
production processes from using highly enriched uranium to low-enriched
uranium. At a recent IAEA meeting in Vienna, problems related to bottlenecks
and target modification and optimization of low-enriched uranium-based 99Mo
production processes were discussed. Ceramic UO2-pellets (as used in fuel)
were excluded from the discussion with the argument that this material cannot
be dissolved under practically applicable conditions. In this paper, we
suggest transforming the non-soluble ceramic UO2 fuel-pellets into the U3O8
form by simple oxidation and the use of the soluble U-oxide modification as
the starting material for the 99Mo production processes. Due to the absence
of Al, larger target quantities could be processed and the waste volume could
still be kept small. The approach is known and proven in nuclear technology.
In principle, this new head process can be connected to any of the presently
used 99Mo production procedures. |
