[en] From the detailed analysis of the once-through transmutation scenario of americium and curium in moderated target assemblies in sodium-cooled fast reactors, it has been underlined the large technological impact of the curium management on the target cycle and especially on the fabrication process and plant. Because of the high heat decay and neutron emission of curium, any dry or wet fabrication process will require remote handling and continuous cooling and will be set up in hot cells, behind thick concrete shields, from the conversion to the assemblies mounting units and during transport. The target fabrication facility should look like to the La Hague vitrification plant. That means that one of the priorities in the further R and D programme on P and T should be to develop simple, compact and robust fabrication processes for TRU fuels and targets. VIPAC and SPHEREPAC processes are thought to be promising. (author)
