The MIRAGE project aims to offer a set of micro and millifluidic tools, platforms and methods to accelerate, intensify and make more flexible R&D on new processes for recycling future plutonium-rich spent nuclear fuels while minimizing the quantities of nuclear materials used.
The LRGP (Reaction and Process Engineering Laboratory of Nancy) is involved in the MIRAGE project alongside the CEA concerning the modeling and experimental strategy aspects of a batch dedicated to the screening of chemical systems and the acquisition and modeling of kinetic and hydrodynamic data of interest. The main task for the LRGP is task 2.3 in strong connection with the CEA and the LGC (Laboratoire de Génie Chimique de Toulouse) (tasks 2.1 and 2.2). The main lines of this task are the development of dedicated simulation tools and their implementation for the optimization of operating conditions allowing in particular to decouple processes (chemical kinetics, transfer limitations and hydrodynamics).
The modeling of phenomena (hydrodynamics, chemical kinetics, interfacial transfers) and the development of dedicated numerical tools for simulation and decision support are major challenges for Process Engineering in general and the field of liquid extraction-liquid in particular. The objectives of these tools are multiple and complementary:
• Sensitivity analysis of parameters, sizing and choice of optimal operating conditions of experimental data acquisition systems. These aspects of experimental strategy make it possible to drastically reduce the number of experimental tests and ensure the accuracy of the measurements made.
• Determination of the characteristic parameters of the various processes measured and in particular the material transfer constants occurring during extraction.
• Determine the optimal experimental technology.
These dedicated and flexible tools allowing to identify and quantify all the local phenomena, their development will allow to feed more generic codes developed for many years (even the PAREX code) in characteristic parameters, to validate them but also, if necessary, to make them evolve by adding a number of processes not taken into account so far such as interfacial processes, transfer limitations, etc.
The data on which this work will be based will be acquired as part of the Lot1-task 1b thesis. The digital tools then developed will help to better define the experiments to be carried out in tasks 1a and 1b of Lot 1.
