2023:11 Study of degradation of spent fuel’s structural material and core components under long-term wet storage
SSM perspective Background Sweden is managing the spent nuclear fuel and core components from its commercial nuclear reactors with a national strategic plan. The fuel and core components are initially stored at the reactor site. After an on-site storage period to comply with transportation limits on decay heat and radiation, these materials are shipped to the Clab (Central Interim Storage...

2024:01 Stress field modelling of the Forsmark lens – Correlation of stress measurements with stress field simulations
SSM perspective Background and objective Understanding the in-situ stress field in the Forsmark tectonic lens will lay the fundamental basis to characterise the prevailing mechanical and hydraulic behaviour of the rock mass. Only with a good understanding of the geomechanical setting including the stress field an analysis of future rock mass behaviour under the evolution of conditions in a...

2023:14 Effect of gamma-irradiation on the redox states of the structural iron in bentonite clay
SSM perspective Background Bentonite clay is used as buffer and backfill material which form engineered barrier in the spent fuel repository. The buffer material surrounding the copper canister will be exposed to gamma and neutron radiations, especially during the first few hundred years after closure of the repository. The redox states of the structural iron in montmorillonite, the dominant...

2003:16 Radon in Estonian dwellings. Results from a National Radon Survey
A countrywide survey of radon concentrations in Estonian dwellings was carried out during the period 1998-2001. The survey formed a part of the cooperation program on radiation protection between the Estonian Radiation Protection (Kiirguskeskus) Centre and the Swedish Radiation Protection Authority (SSI). The Estonian Environmental Foundation and the Swedish Ministry for Foreign Affairs have...

2002:23 Validation of dose calculation
This report describes a validation of the computer codes RESRAD-RECYCLE and CERISE, which are used to estimate radiation doses due to the recycling of scrap metal. Calculated external radiation doses to individuals are compared with measured data from different steps of the processing of slightly contaminated material, mainly in Studsvik, Sweden.
