ABSTRACT
The purpose of this work is the replacement
of the current targets of High Enrichment Uranium (HEU-90% p. 235U) by a
uranium compound of low enrichment (LEU-20% p. 235U) for production of fission
Mo99, using a dispersed uranium Aluminum phase.
This work describes the
manufacturing of UAl2 compound and the powder metallurgical compact process
with an approximate density of 3 gU/cm3 in the targets.
With this load of uranium reached
in the targets, Uranium Aluminum can be replaced the current miniplate of High
Enrichment Uranium (HEU), without any geometric modifications and maintaining
the current process of basic dissolution in the radiochemical process.
The Uranium Aluminide compound
was selected due to its very convenient characteristic, specially in density it
is 6,42 g/cm3.
