Forskning
Strålsäkerhetsmyndigheten finansierar årligen forskning för cirka 120 miljoner kronor. Syftet är att stärka myndighetens och Sveriges kompetens på området. Vi tar också fram föreskrifter, ställer krav på, utövar tillsyn, registrerar anmälningar och ger tillstånd till den som bedriver forskning...

Strålskyddsexpertfunktion
Tillståndspliktiga verksamheter med joniserande strålning ska ha tillgång till en strålskyddsexpertfunktion enligt 3 kap. 13 § i Strålsäkerhetsmyndighetens föreskrifter (SSMFS 2018:1) om grundläggande bestämmelser för tillståndspliktig verksamhet med joniserande strålning.

Att arbeta strålsäkert
Den som har tillstånd att driva verksamhet med joniserande strålning är också den som har ansvaret för personalens strålskydd. Informationen på den här sidan är främst riktad till dig som är tillståndshavare. Du måste följa Strålsäkerhetsmyndighetens föreskrifter och se till att personalen...

2013:28 Brine intrusion by upconing for a high-level nuclear waste repository at Forsmark. Scoping calculations
The objective of this study is to evaluate the possibility of salt-water migration to the spent nuclear repository. This objective is motivated by the adverse impacts of water with too high salinity entering the repository and by the uncertainty of the relevant hydraulic and hydrogeochemical conditions at the Forsmark site at great depths. To analyse density dependent flow and salt transport...

2012:71 Identification of Brittle Deformation Zones and Weakness Zones
In preparation for the review of Swedish Nuclear Fuel and Waste Management Company’s (SKB) license application for disposal of spent nuclear fuel, Swedish Radiation Safety Authority (SSM) is conducting studies to evaluate the performance of the multi-barrier principle on which the KBS-3 concept is based. Copper canisters containing the spent nuclear fuel are placed into granitic bedrock at...

2012:61 Geochemical Constraints on Buffer Pore Water Evolution and Implications for Erosion
Mineralogical data from the Forsmark Site show that smectite and calcite occur at all depths in Forsmark fractures, with no evidence for removal/dissolution by previous glacial episodes. This natural analogue information implies that these minerals may not have been eroded/dissolved during previous glacial episodes. Available thermodynamic data suggest that repository-depth Forsmark...

2011:34 Evolution of hydrogen by copper in ultrapure water without dissolved oxygen
One result from this research was that the experimental difficulties of repeating Hultqvist and co-workers work are considerable and were initially underestimated. The main challenge was to obtain satisfactory tightness of all connectors involved in the experimental set-up. The problems with leakage resulted in that the research program originally planned for in this project had to be reduced...

2011:09 Is Copper Immune to Corrosion When in Contact With Water and Aqueous Solutions?
The KBS-3concept implies that spent nuclear fuel is placed in copper canisters surrounded by clay and finally placed approximately 500 m down from surface into granitic bedrock, in order to isolate the spent nuclear fuel from humans and environment for very long time scales (i.e. millions of years). The concept is based on the multi-barrier principle, in this respect the barriers are the...

2018:21 Research on Resaturation of Bentonite Buffer
Background Resaturation processes in the bentonite buffer in a KBS-3 type repository for spent nuclear fuel are complicated and are often illustrated, analysed and modelled multi-disciplinarily as coupled thermal (T), hydrological (H) and mechanical (M) processes with multi-phase flow, elastoplastic evolution in a swelling porous medium. Previous THM-modelling showed that the re-saturation...

2018:23 Evaluation of the Impact of the Model Additional Protocol on Non-Nuclear-Weapon States with Comprehensive Safeguards Agreements
Background The Swedish Radiation Safety Authority (SSM) called for research proposals related to Non-Proliferation. This call resulted in SSM accepting a proposal from the Vienna Center for Disarmament and Non-Proliferation (VCDNP) to evaluate the impact of the implementation of Additional Protocols (AP). The Additional Protocol, which was approved by the International Atomic Energy Agency's...
