• Strategies and planning of decommissioning 

Acquis
d'apprentissage

A la fin de cette unité d’enseignement, l’étudiant est capable de :
1	MOX and Th fuel To get a global understanding of the utilization of  Pu and Th based fuel in light water reactors: The challenges of the U-Pu-MOX fuel regarding the fuel fabrication, the core and fuel neutronic aspects and fuel behaviour The Th-Pu-MOX used in LWR for its breeding capabilities, or more realistically as matrix for Pu utilization.   Radiochemistry and Dismantling To get an understanding of radiochemistry, as it is a basic discipline to understand the various stages and activities in the nuclear fuel cycle, including the safe disposal of the radioactive waste.   To get acquainted with the principles and practice of dismantling and decommissioining of nuclear materials, as this is becoming an activity of increasing importance in nuclear engineering.
