Abstract A Swiss expert group recently developed a new concept for the disposal of radioactive waste called “Monitored Long-Term Geologic Disposal”. This concept aims to combine the advantages of final geological disposal in terms of long term passive safety, with some of the advantages of active safety attributed to long term monitored underground storage: As soon as the waste has been emplaced in the Main facility, the caverns or drifts of the facility are backfilled and sealed. Backfill and sealing of the access and service tunnels of the Main facility may be delayed for long times leaving the final decision to future generations. During this period, a high degree of reversibility is maintained. In addition, some representative volumes of waste will be disposed of in a separate Pilot facility for long term monitoring with the aim of validating long term safety predictions as well as identifying possible early indications of repository failure. The new concept of Monitored Long-Term Geologic Disposal forms the basis for the new law on nuclear energy currently under discussion in the Swiss parliament.
