What is it about?
In this work we investigate the thermal decomposition of an Uranium alloy with 9% Nb and 3% Zr, which is obtained in the body centered cubic phase by processing. The results show a complex decomposition sequence and its relation with diffusion in the solid state.

Why is it important?
Developing a new nuclear fuel is done in three layers 1) the correct microstructure must be developed by processing 2) this structure must be shown thermally stable (or at least the limitations of stability must be known) a 3) this microstructure must be shown stable under irradiation. The present work is dedicated to the second layer.
Perspectives
This is another contribution of my long time collaborator, Dr. Nathanael Wagner Sales Morais and shows our on going contribution to the development of innovative nuclear fuels for research and compact reactors.
