A study has been performed into the feasibility and economic consequences of storing radioactive waste deep underground in a retrievable way. Based on storage in heavy containers, two extreme options of retrievability have been investigated. One option is placement of the containers in an underground gallery and backfilling only the actual storage galleries, and keeping the repository in operational condition. The other option is placement in the galleries followed by backfilling and sealing the complete repository including the shafts. In the latter case, construction of a complete new mine is necessary once retrieval of the waste becomes imperative. In the first option the operational cost of the repository is an annual returning expenditure while in the second option the re-mining creates a large capital expenditure in the far future. Several methods of retrieval have been compared and the most feasible method selected for economic assessment. An extensive temperature analysis has been performed both of an individual container and of the complete repository. The consequences of the storage and retrieval of the hot waste containers for the stability of the underground excavations have been investigated using numerical models.
