N2 - In 1974 S.C.K./C.E.N. launched a R&D-programme concerning the possibilities for disposal of high level solidified and alphabearing radioactive wastes in a continental stratiform clay formation (Boom clay) situated below its own site. Since 1983 ONDRAF/NIRAS has financially been participating in the project and the studies have for sometime been re-orientated in order to comply with an industrial disposal adapted to Belgian waste. The direct demonstrations deal with the constructibility of real scale galleries without treatment of the rock, the choice and dimensioning of a realistic lining and support system, the interaction between the underground structures and the immediate geological environment, the handling of hot and radioactive canisters, the backfilling and its behaviour with time, and the performance of various system components during the operational phase and of monitoring systems. Within the HADES project a technological test related to a gallery lining technique according to the convergence-confinement principle has been performed by ANDRA (France) and geotechnical interpretation has been made by GCG (Great Britain). This paper summarizes the results obtained during the period 1985-1989.
