Innovative approaches for improved management of transuranium elements
are being sought. The use of either metallic or nitride fuels, couple
d with pyrochemical reprocessing techniques, are being studied. As our
experience with these advanced fuels is limited, their development wi
ll be promoted by thermochemical analysis. This paper reviews our ther
mochemical modeling of technical problems related to advanced fuel cyc
les and presents models of the actinide alloys and nitrides together w
ith experimental verification of these thermochemical predictions. (C)
