Transmutation and incineration is one of the several options being considered for the handling of actinides following their seperation from spent nuclear fuel. The fabrication of such irradiation fuels and targets could be achieved using conventional powder mixing, pellet pressing and sintering routes. Despite the successful application of this method for the production of uranium and MOX fuels, the handling of fine, highly radioactive actinide powders could pose extra difficulties.
In the Institude for Transuranium Elements two alternative methods which avoid dust production have been developed. The Sol-Gel process is a wet fabrication route for the production of microspheres which are then pressed into pellets. This method has been used to prepare (U0,96PU0,02Am0,02)O2 pellets. The second method has been used to fabricate targets containing 11% Am and 3% Pu by infiltration of the respective nitrate solutions into green spinel pellets.These fabrication routes and the characteristics of the products obtained are described and compared.
