Abstract

After 30 years of research in the field of nuclear waste disposal, the remaining scientific issues are described. They include long-term monitoring during the reversible period, early coupled processes during the thermal phase, effect of hydrogen generated by corrosion, and volume expansion. The long term behavior of waste packages has been thoroughly investigated, but controversial issues have still to be resolved. In situ investigations concerning the speciation and migration of radionuclides are needed. Concerning the developement of future nuclear systems, a roadmap on waste management issues has to be established.
