The German strategy of handling spent fuel was focussed on reprocessing since the 1960s although the German breeder projects are phased out since the late 1980s. Therefore, considerable plutonium was separated from German spent fuel and not reused. Some materials are not storable without periodical treatment and must be processed. The question arises whether a product can be fabricated that is also suitable for final disposal. Fabrication of “MOX storage rods” is considered to be the best treatment, especially under German conditions, for this purpose. This treatment can also reduce costs significantly, probably up to one third. The storage rod option is based on techniques of which Europe has large-scale technical experience and only existing facilities are needed. Relevant amounts of plutonium could be processed in a relatively short time, this means several tons per year, starting before 2005.
