Margin to fuel melting
Coordinated by Dragos Staicu, JRC (EU)
This work package is focused on the determination of fundamental material properties needed for the
evaluation of the MOX fuel margin to melting for various burnâups and in presence of Am. Existing phase
transition data need to be assessed comprehensively with the help of structural material characterization
and computational thermodynamic optimisation (task 1.1). In addition, further data are still necessary on
the thermal conductivity behaviour of these fuels, particularly as a function of increasing burnâup (task
1.2). Atomic scale calculations will complete the data assessment and provide an estimate of material
properties complex to measure directly, in particular specific heat evolution in the investigated materials
(task 1.3). The results obtained will be transferred to task 6.3
