THE POTENTIAL OF DIFFERENT CONCEPTS OF FAST BREEDER REACTOR FOR THE FRENCH FLEET RENEWAL

摘要

The performances of different concepts of Fast Breeder Reactor (Na-cooled, He-cooled and Pb-cooled FBR) for the current French fleet renewal are analyzed in the framework of a transition scenario to a 100% FBR fleet at the end of the XXIst century.rnFirstly, the modeling of these three FBR types by means of a semi-analytical approach in TIRELIRE -STRATEGIE, the EDF fuel cycle simulation code, is presented, together with some validation elements against ERANOS, the French reference code system for neutronic FBR analysis (CEA).rnAfterwards, performances comparisons are made in terms of maximum deployable power, natural uranium consumption and waste production.rnThe results show that the FBR maximum deployable capacity, independently from the FBR technology, is highly sensitive to the fuel cycle options, like the spent nuclear fuel cooling time or the Minor Actinides management strategy.rnThus, some of the key parameters defining the dynamic of FBR deployment are highlighted, to inform the orientation of R&D in the development and optimization of these systems.
