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...

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...

2024:17 Atomistic studies on the adsorption and desorption of radionuclides on fuel crud and system surfaces in Light Water Reactors
SSM perspective Background Radiation safety is of particular concern during power plant maintenance. Radionuclides produced by the neutron bombardment in the core during operation may accumulate on system surfaces such as the filter system or piping and contribute to the radiation field. Some ions that are prone to neutron capture often become trapped in the deposits on the fuel cladding...

2024:18 Modelling Environmental Sensitization of Chromia Forming Nickel Base Alloys Toward Stress Corrosion Cracking in Light Water Reactors by Atomistic Simulations
SSM perspective Background Stress corrosion cracking (SCC) in load bearing structures has been a longstanding issue both in pressurized and boiling water reactors. The specific environment in nuclear power applications consists of high temperatures and pressures that together with the effects of the radiation field on the coolant composition provide tough conditions for the materials used in...

CONNECT-NM: Euratom partnership for research on nuclear materials
CONNECT-NM is a partnership within Euratom focusing on research related to nuclear materials, primarily in-core structural materials, concrete, fuel cladding and fuel. The Swedish Radiation Safety Authority (SSM) participates in the partnership and leads the creation and management of an advisory body of European regulators. The goal is to facilitate dialogue between regulatory authorities...

2025:02 INCLUDE: Including (local) stakeholder participation in the regulatory mission – a future challenge
SSM perspective Background The primary focus of SSM’s communication with stakeholders in relation to the disposal of spent nuclear fuel and nuclear waste has for several years been on formal consultation processes surrounding the Swedish nuclear power industry’s research and development programme as well as SKB’s licence applications under the Nuclear Activities Act. Following licensing by...

2026:04 3D Discrete Element Modelling of Fluid Injection Induced Fault Slip in Argillaceous Rock – Mt.Terri Fault Slip Experiment
SSM perspective Background and objective It is a well-known phenomenon that artificial increased in pore pressure at depth, due to subsurface fluid injection, can trigger earthquakes (Walsh and Zoback 2015, and references therein). Increased pore pressures at depth can also occur naturally, for instance due to the pressure changes imposed by a waxing and waning ice sheet. A geological...

The international radiation protection school in Stockholm attracts participants from over 20 countries
For five days, at Stockholm University, international early and mid-career radiation protection experts gather to develop their knowledge in radiation protection. The course alternates between theory and practice and provides in-depth knowledge and understanding on the structure and application of the international system for radiation protection.
