title = "Concept and safety assessment for final disposal of spent nuclear fuel in Finland",
abstract = "The current obligations and long term plans for management of spent nuclear fuel are presented. The use of safety analysis in respository development and site selection is discussed on the basis of the analyses performed. The general principle for final disposal of spent fuel in Finland is a multibarrier system. The spent fuel assemblies are assumed to be enclosed in copper canisters which will be emplaced in boreholes in the floors of disposal tunnels and surrounded by buffer material. The final repository is assumed to be built at a depth of 500 m in the bedrock. Safety analysis, based on system models consisting of repository, geosphere and biosphere modules, was carried out employing the scenario technique. The choice of scenarios was based on a comprehensive analysis of anticipated situations as well as disturbed evolution and disruptive events with low probabilities. The conservative analyses indicate that the disposal concept easily meets the safety objectives proposed by international organizations. Owing to the high safety margins optimization of the engineered barrier system can be considered in the future.",
