This study focuses on planning and evaluating alternative concepts for dealing with the back-end of the nuclear fuel cycle. Emphasis is placed on the underground part of this system for the disposal of radioactive waste/spent fuel that generates considerable heat. A certain amount of spent fuel discharged from LWRs is subject to disposal or reprocessing. For the emerging mix of waste and spent fuel packages, many disposal variants are designed conceptually, thereby providing the database for further near- and far-field analyses as well as dose and cost calculations. The technical alternatives are compared on the basis of seven criteria. Concept BD1 (borehole and drift emplacement) and concept D3* (three-level drift emplacement) best meet the requirements stated. The comparative analysis also highlights areas of insufficient knowledge which introduce a degree of uncertainty into the systems evaluation.
