The PAREX Code: A powerful tool to model and simulate solvent extraction operations

Abstract : The PAREX code has been developed since the nineties by CEA and AREVA to describe the PUREX process implemented in the French fuel reprocessing plants. It enables the calculation, either in steady or transitory states, of the behaviour of the different elements of interest at each process step. The highly customised structure of the software allowed the implementation of various phenomenological models describing solvent extraction systems dedicated to uranium purification from crude ore to spent fuel. After qualification of the implemented models, the code was used to design flow sheets for safety demonstration analysis or for operational assistance. CEA is currently developing a new simulation platform to make the code PAREX perennial and associate it with tools included in a standardised computing background for their perpetuation and sharing of generic functionality. In particular, it is planned to develop validated databases to reference the scientific knowledge useful in modelling development. The platform will adapt the standard phenomenological complexity needed to simulate a reprocessing plant, real or virtual, share tools and improve the transposition from laboratory scale to industrial scale, thus decreasing the number of experimental studies required for the implementation of a process.
