Towards an optimized flow-sheet for a SANEX demonstration process using centrifugal contactors
Abstract The design of an efficient process flow-sheet requires accurate extraction data for the experimental set-up used. Often this data is provided as equilibrium data. Due to the small hold-upExpand

Futuristic back-end of the nuclear fuel cycle with the partitioning of minor actinides
For future back-end of the nuclear fuel cycle, the partitioning of minor actinides: Np, Am and Cm, followed by their transmutation will minimize importantly the radiotoxicity of nuclear glass waste.Expand
