Abstract

 Chemistry has been necessary to the development of nuclear energy in the early phases, from mining activities to final waste confinement; solvent extraction technologies have been boosted by nuclear industry, and now, it appears that chemistry could be an essential tool for facing its tomorrow’s challenges. So called “generation IV” nuclear systems should be based on systematic and enhanced separation processes for both efficient recycle of valuable elements and drastic decrease of waste long-term harmfulness; innovative cladding materials for nuclear fuels could offer drastic improvement of safety features; and on-line liquid fuel treatment for molten salts reactors could pave the way for quite new nuclear systems… This 2.6 symposium is divided into three sessions, each dedicated to one of the main nuclear issues concerned by chemistry: - the first one will deal with advances in fuel cycle processes ( industrial records, routes for improvement, main scientific challenges); - the second one will address the today very tough issue of final waste management; - the third one will be dedicated to possible break-through in materials and nuclear systems, focusing research today for possible industrial applications in the future).
