2012:63 Technical Note, Review of Radionuclide Sorption on Bentonite and Forsmark Bedrock Material
Denna rapport granskar sorption-data för bentonit och berg vilka har använts i säkerhetsanalysen SR-Site. Det kan konstateras att härledningen av Kd-värden har gjorts på ett systematiskt sätt och att presentationen av resultat är uttömmande. Kontroller visar att härledning och överföring av resultat kan betraktas som spårbar. Det...

2013:34 Technical Note, Seismology – Post-glacial seismicity and paleoseismology at Forsmark
Metoden som SKB använder för att förutse seismisk risk för slutförvaret skiljer sig i två avseenden från gängse förfarande. För det första, förkastningsrörelser inom förvaret är beräknade utifrån numeriska bergmekaniska modeller i stället för genom en Probabilistisk riskanalys för förkastningsrörelse...

2013:07 Corrosion of copper in distilled water without molecular oxygen and the detection of produced hydrogen
In this report, results are presented for copper which has been exposed to pure anoxic water in the temperature interval of 21 °C to 55 °C up to a total of 19 000 hours. Characterisations of copper surfaces after exposure have been performed ex-situ, meaning after termination of the experiment and exposing the specimen to normal atmospheric environment. Ideally characterisation of surfaces...

2012:68 Assessment of cost for dismantling of Ringhals 2 PWR
The Financing Act stipulates that future expenses for dismantling of Nuclear Power Plants (NPP) shall be financed from segregated funds that are supervised by the Swedish Nuclear Waste Fund (SNWF). Transparency of and confidence in the process to ensure collection of sufficient funds is fundamental for the acceptance and sustainability of the Swedish model for estimating environmental...

2019:14 IAEA Safeguards: Staying Ahead of the Game
SSM perspective Background The Swedish Radiation Safety Authority (SSM) called for research proposals relating to non-proliferation. This call resulted in SSM accepting a proposal from the Vienna Center for Disarmament and Non-Proliferation (VCDNP) on “Improving IAEA Safeguards for Non-Proliferation and Disarmament: Assessing the Options for, and Feasibility of, Further Strengthening...

2010:32 Fingerprints of zones in boreholes An approach to identify the characteristics of structures
This report concerns a study which was initially conducted for the Swedish Nuclear Power Inspectorate (SKI), which is now merged into the Swedish Radiation Safety Authority (SSM). The conclusions and viewpoints presented in the report are those of the authors and do not necessarily coincide with those of the SSM. The Swedish Nuclear Fuel and Waste Management Co (SKB) has published Site...

2010:08 Development of COLLAGE 3
The issue of colloid-facilitated radionuclide transport (CFRT) was last addressed by the Swedish nuclear regulators (SKI at that time, now integrated into SSM) in 2001 – 2002. SKI had commissioned the Collage code with subsequent development as Collage 2. This code was employed to investigate the potential role for colloids to have been involved in the transport of radionuclides at the Nevada...

2010:34 The understanding of the formation of valleys and its implication on site characterization: Moredalen and Pukedalen, south-eastern Sweden
This report concerns a study which was initially conducted for the Swedish Nuclear Power Inspectorate (SKI), which is now merged into the Swedish Radiation Safety Authority (SSM). The conclusions and viewpoints presented in the report are those of the authors and do not necessarily coincide with those of the SSM. In south-eastern Sweden, there are a number of over-deepened narrow valleys,...

2010:17 Quality Assurance Review of SKB’s Copper Corrosion Experiments
SKB is preparing a license application for the construction of a final repository for spent nuclear fuel in Sweden. This application will be supported by the safety assessment SR-Site for the post-closure phase. The assessment of long-term safety is based on a broad range of experimental results from laboratory scale, intermediate scale and up to full scale experiments. It is essential that...

2010:23 On Decommissioning Costs of the Ranstad Site
A demanding task for the present generation is to assure that appropriate financial resources are injected into the Swedish Nuclear Waste Fund. It will thereby be possible for coming generations to undertake efficient measures in the decommissioning and dismantling of older nuclear facilities. To undertake such measures in the context of Swedish as well as European environmental and health...
