[en] A summary lecture reports on the different types of fast breeder fuel elements, and on their storage and transport. Other subjects are fast breeder fuel fabrication and cutting of fuel elements. In several contributions concerning the reprocessing of fast breeder fuel, there are treated the differences between light water reactor (LWR) and fast breeder (FBR) fuel reprocessing, contributing valuable data especially the experience with reprocessing of KNK II fuel in the MILLI lab scale reprocessing facility. A further main subject relates to future R and D works, including the conception of a FBR fuel reprocessing pilot plant and the employment of electrolytic processes for simplification of reprocessing techniques and reduction of waste, already successfully demonstrated in LWR fuel reprocessing.
