Geologic disposal of LLW in Sweden

In Sweden the primary responsibility for the total radioactive waste management program lies with the nuclear power utilities. Comprehensive R and D and site investigations have been performed since 1977. A transport system and a central AFR-facility are in operation. A final repository for low and medium level wastes, SFR, is under construction and planned for commissioning in early 1988. SFR is located in granitic bedrock under the sea outside the Forsmark nuclear power station. The wastes with the highest radioactivity are deposited in concrete silos in excavated caverns. The silos are surrounded by bentonite clay. Model calculations with input data from borehole investigations and laboratory experiments have shown that the release of radionuclides to the human environment will give a radiation level (dose), that at most will correspond to a few percent of the natural radiation. The total cost for SFR will affect the cost for the electric power with a few percent. A special information program is connected to the SFR project
