2024:05 Recent Research on EMF and Health Risk, Seventeenth report from SSM’s Scientific Council on Electromagnetic Fields, 2022
SSM perspective Background The Swedish Radiation Safety Authority’s (SSM) Scientific Council on Electromagnetic Fields monitors current research on potential health risks in relation to exposure to electromagnetic fields and provides the authority with advice on assessing possible health risks. The Council gives guidance when the authority must give an opinion on policy matters when...

2024:02 Earthquake stationarity and distributed fault displacements, Forsmark repository site
SSM perspective Background and objective Large earthquakes occur predominantly along plate boundaries. Due to this, much of the research have been directed towards this tectonic setting. Also, the general lack of seismicity data in stable continental interiors, such as the Baltic Shield, have impeded estimations, as well as the understanding, of the seismic hazard in these tectonic settings.

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...

2023:05e Radiological Consequences of Fallout from Nuclear Explosions
Summary In this report, Strålsäkerhetsmyndigheten, the Swedish Radiation Safety Authority (SSM), presents an analysis of the potential radiological consequences of fallout from the nuclear explosions at distances between about 10 kilometres and about 300 kilometres from the explosion, and the effect of various protective actions. The contents of the report constitute a knowledge base...

2023:13 TPR 2023 Fire Protection Swedish National Assessment Report
Executive Summary The European Union’s Nuclear Safety Directive 2014/87/EURATOM (NSD) requires the member states to undertake topical peer reviews (TPR) every 6 years. The first topical peer review concerned Ageing management and started in 2017. The member states, acting through the European Nuclear Safety Regulators Group (ENSREG), decided that the topic for the second topical peer review...

2023:12 Investigation of the limits of detection for specific radionuclides in soil from the European Spallation Source (ESS) using radiometric and mass spectrometric methods
SSM perspective Background In Lund, the construction of the European Spallation Source (ESS) research facility is underway and the facility is also undergoing a stepwise licensing procedure in accordance with relevant legal requirements. At ESS, neutrons will be produced by spallation when high-energy protons from a linear accelerator hit a rotating tungsten beam target. The neutrons released...

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...
