This document presents the results of a 'Strategy study on nuclear waste trasmutation' which has been executed in collaboration with AEA Technology, CEA and Siemens. Firstly, the motivation for transmuting long-lived radioactive products has been formulated; next, transmutation of Tc-99 and I-129 has been studied considering the pressurized water reactor (PWR) heavy water reactor (HFR), Superphénix, and the CANDU reactors. This study has been amended by a graphical representation of important reactions for activation of cladding and inert matrix materials. By means of the derived new data libraries, some sample calculations on transmutation of americium in thermal reactors have been performed. Implications of recycling plutonium and americium in the form of MOX fuel in light water reactors have been investigated. It became clear from the study that transmutation of the existing plutonium has the highest priority and that reduction of minoractinides is next on the priority list. Thirdly, the (difficult) large-scale transmutation of Tc-99 and of I-129 could reduce the leakage dose risks. It also seems worthwhile to be careful with naturally occurring U-234 in the water, as this will in the long run lead to a substanial increase of the 'natural' radon dose in the neighbourhood of the storage facility.
