| abstract |
The invention relates to a process for the treatment of a metal oxide powder, particularly a UO 2 or PuO 2 powder, with a view to its fritting. n This process consists of oxidizing the powder, so as to form on its surface a hydrated oxide layer of the same metal. When the oxide is UO 2 or PuO 2 and mixtures thereof, as well as those prepared with ThO 2 , the treated powder can be used for producing nuclear fuel pellets by cold compression, followed by fritting. |
