• 2009:14 Review of Legislation and Regulatory Framework in Ukraine with Regard to Environmental Radiation Monitoring

  This report was written in the frames of the development cooperation project in Ukraine entitled “Environmental Radiation Monitoring”. This report concerns a study which has been conducted for the Swedish ... viewpoints presented in the report are those of the author/authors and do not necessarily coincide with those of the SSM. In 2006, the Swedish Radiation Safety Authority (SSM), with the support of the Ministry...

• 2009:36 Recent Research on EMF and Health Risks. Sixth annual report from SSM:s independent Expert Group on Electromagnetic Fields 2009

  A large number of cell studies are done on both genotoxic and non-genotoxic outcomes, such as apoptosis gene expression. There are no new positive findings from cellular studies that have been well established ... established in terms of experimental quality and replication. Potential heating of the samples is still seen as a major source of artefacts. Moreover, these few positive results are not related to each other...

• 2009:38 Research and Development Program in Reactor Diagnostics and Monitoring with Neutron Noise Methods, Stages 14 and 15

  constitutes Stages 14 and 15 of a long-term research and development program concerning the development of diagnostics and monitoring methods for nuclear reactors. Stage 14 was a full one-year project, whereas ... whereas Stage 15 consisted of a half-year project. Results up to Stage 13 were reported in SKI reports, as listed below and in the Summary. The results have also been published in international journals and...

• 2009:22 Alternative modelling of brittle structures in a sub-area of the SKB candidate area at Forsmark, eastern Sweden

  A reasonable understanding of the character of the bedrock hosting a deep geological repository, i.e. the natural barrier, is an important component in the safety assessment of the deep geological repository ... structures in the rock, together with the regional stress field, affect the mechanical stability of the bedrock and the ground water transport within the bedrock. The rock types, the alteration of the bedrock...

• 2009:16 Influence of Hardening Model on Weld Residual Stress Distribution

  stresses have a large influence on the behavior of cracks growing under normal operation loads and on the leakage-flow from a through-wall crack. Accurate prediction of these events is important in order to ... for assessment of leak-before-break margins. Therefore, it is very important to have verified procedures to estimate weld residual stresses (WRS). During the latest years, there has been a strong development...

• 2009:30 A Review of Evidence for Corrosion of Copper by water

  repository in Sweden relies on a copper cast iron canister as the primary engineered barrier. The corrosion behaviour of copper in the expected environment needs to be thoroughly understood as a basis for ... corrosion may indeed be the primary canister degradation process during the utilised assessment period of 1 million years (this period is the longest time for which risk calculations will be needed according...

• 2009:31 A Review of the Decommissioning Costs of the Ranstad Site

  main objective of this study has been to review the future cost to decommission and dismantling the industrial area at the site of the old uranium mine at Ranstad in Sweden. Analyses of some detailed comparative ... information have been used in the context of preliminary “bench-marking” studies. The estimated costs for decommissioning of the old uranium mine in Ranstad have been compared with actual costs from other...

• 2009:33 Workshop on spent fuel performance, radionuclide chemistry and geosphere transport parameters, Lidingö 2008: Overview and evaluation of recent SKB procedures

  assessment for disposal of spent nuclear fuel canister in the Swedish bedrock should thoroughly address the time period after a containment failure. Such a failure could be expected as a result of corrosion damage ... transport calculations in the areas of spent fuel performance (for fuel in contact with groundwater), radionuclide chemistry, and sorption and geosphere transport parameters. Some examples of topics that are...
