New nuclear power units in Sweden may not be commissioned until the owner has shown that the radioactive waste problem can be solved in an absolutely safe manner. Options for the safe final storage of vitrified waste and of spent nuclear fuel are explored. Vitrified wastes can be stored in the form of borosilicate glass cylinders containing 9% fission products. The cylinders will be surrounded by 10 cm of lead, which is further encased in a titanium canister. The canisters are placed in deposition holes drilled in the tunnel floor. The holes are backfilled with a sand-clay mixture. Spent fuel assemblies can be dismantled and the rods encased in copper containers with 20 cm thick walls. The cylindrical containers can be deposited into holes drilled in the floor of a tunnel system. The spaces between the rock and the copper cannisters can be filled with compacted bentonite clay.
