FUEL ELEMENT FOR BURNING ACTINIDES

The object of the invention is the production of a fuel element capable of containing the actinide alone, under conditions ensuring that its integrity is maintained throughout the incineration process and allowing the recovery of the incineration products. This is achieved by an element having a tub...

Beschreibung
Zusammenfassung:	The object of the invention is the production of a fuel element capable of containing the actinide alone, under conditions ensuring that its integrity is maintained throughout the incineration process and allowing the recovery of the incineration products. This is achieved by an element having a tubular outer sleeve (30) and a tubular inner jacket (38), coaxial with the sleeve, so as to define an annular cavity (44) for receiving actinide particles (46) to be incinerated and a central inner space (42), wherein the inner jacket (38) is made of a material permeable to the incineration gases, but impermeable to actinides, and extends over a portion of the length of the sleeve (30) so as to define at least one expansion chamber (40) with which the central inner space (42) communicates.
