• 2011:12 Analysis of Barrier Performance: Modelling of Copper corrosion scenarios with and without buffer erosion

  The purpose of this project was to develop a numerical modelling capacity to address the corrosion of the copper canister under gradually changing transport conditions caused by buffer erosion and removal of buffer mass. Due to the complexity of this task, such a model cannot be realistic in all respects, but the present effort should address the feasibility of solving numerical and...

• 2011:11 Handling Interfaces and Time-varying Properties in Radionuclide Transport Models

  Quintessa’s QPAC code has been used to investigate the Qeq approach. The conclusions from this simulation study are the following. The basic approach to calculating Qeq values is sound, however, narrow channels could lead to the same release as larger fractures with the same pore velocity, so a channel enhancement factor of √10 should be considered. A spalling zone that increases the area of...

• 2013:32 Upparbetning av utbränt kärnbränsle - En studie med fokus på exportkontroll

  Rapporten beskriver principerna för upparbetning samt egenskaperna hos utbränt kärnbränsle där sammansättningen hos det i reaktorn bildade plutoniumet är av avgörande betydelse för kärnvapenframställning till skillnad från civil upparbetning. Rapporten går igenom ett antal upparbetningsmetoder, både äldre metoder samt nya,...

• 2010:39 Beskrivning av Eurokoder för betongkonstruktioner

  Eurokoder, som är gemensamma europeiska standarder för utformning och dimensionering av bärande konstruktioner till byggnader och anläggningar, utarbetas av den Europeiska Standardiseringskommittén (CEN) och ges i Sverige ut av det svenska institutet för standarder (SIS). Sverige, liksom de andra CEN-medlemsländerna, är i färd med att ersätta sina...

• 2007:02e Radiation Environment in Sweden, summary

  The radiation environment to which the population of Sweden is exposed is dominated by medical investigations and background radiation from the ground and building materials in our houses. That is the conclusion of the first general Swedish summary of environmental monitoring data and dose calculations within the field of radiation. The report shows that people’s behaviour in the form of...

• 2021:03 Updated radiological risk assessment for the “Radon” type surface disposal facility in Chisinau, Moldova

  SSM perspective Background Bilateral cooperation between Sweden and the Republic of Moldova in nuclear and radiological safety and security has been ongoing since 2010, focusing on activities aimed at strengthening the institutional capacity of the National Agency for Regulation of Nuclear and Radiological Activities in Moldova (NARNRA) as well as infrastructure development in radioactive...

• 2021:06 Quality Assurance Review of the Swedish Nuclear Fuel and Waste Management Company’s LOT Experiment (Phase S2 and A3) at the Äspö Facility in Sweden

  SSM perspective Background This report presents a quality assurance (QA) review of the work done by SKB to retrieve the S2 and A3 parcels from the Long term test of buffer material (the LOT experiment) at the Äspö Hard Rock Laboratory. Each LOT parcel comprises a heated copper tube surrounded by bentonite, with a number of copper coupons and various other test and monitoring instruments...

• 2021:14 Reliability, Feasibility and Significance of Measurements of Conductivity and Transmissivity of the Rock Mass for the Understanding of the Evolution of a Repository of Radioactive Waste

  SSM perspective Background The conducted research was part of the international research project DECOVALEX 2019 (DEvelopment of COupled models and their VALidation against EXperiments). DECOVALEX 2019 consisted of seven different research projects called Task A to G. SSM were involved in Task G, which were composed of three different teams from Technical University of Liberec (TUL), Seoul...

• 2022:08 Geophysical surveys on sub marine land- and rock slides and on alpine glaciers

  SSM perspective Background The future climate evolution and the impact it might have on a repository for radioactive waste is important when assessing the long-term safety. In a project funded by SSM (Holmlund et al. 2016), bathymetric data from the Southern Quark area between Sweden and Åland, provided by the Swedish Maritime Administration, were analysed, as well as terrestrial data from...

• 2024:02 Earthquake stationarity and distributed fault displacements, Forsmark repository site

  SSM perspektiv Bakgrund och syfte Stora jordbävningar inträffar huvudsakligen längs plattgränser. På grund av detta har mycket av forskningen riktats mot denna tektoniska miljö. Den allmänna bristen på seismicitet i stabila kontinentala områden, såsom Baltiska Skölden, har försvårat uppskattningar, såväl som förståelsen,...
