Sažetak
Although KBS-3V is probably the most thoroughly analysed spent nuclear fuel (SNF) disposal concept, and it will be the first concept applied in an actual repository, it is debatable whether KBS-3V is the best and the most feasible concept. Disposal tunnels will be constructed by the drilling and blasting method and the canister emplacement holes by large diameter drills, which means a greater excavation disturbed zone (EDZ), more excavated material and potentially complicated stress/strain models. Another issue is the complicated separate ventilation system and potential problems with bentonite buffer emplacement. An alternative concept, axial emplacement in disposal tunnels, developed by NAGRA and NWMO, offers a smaller repository footprint (for the same number of SNF canisters), a significantly reduced EDZ, a reduced volume of excavated material, a simpler ventilation system and emplacement of the bentonite buffer in the form of pellets. In this paper, both aforementioned concepts will be compared and discussed from the mining engineering point of view.
