The co-precipitation of tetravalent actinides as an oxalate single phase is currently considered as a promising option to improve the homogeneity as well as the sinterability of mixed oxides fuels envisaged in several concepts of Gen-IV nuclear reactors [ ]. Even if actinides oxalates are studied since several decades in this purpose, some uncertainties remain about the associated...

The understanding of dissolution processes of actinides dioxides has become essential for the optimization of reprocessing operations associated to the back-end of nuclear fuel cycle. As several GenIV reactor concepts plan to operate the simultaneous reprocessing of majors and minors actinides (such as AmIII and CmIII) in new fuel elements, we focused a study on the influence of the...
