A step-wise review
The Swedish Radiation Safety Authority (SSM) prepares licence applications under the Swedish Act on Nuclear Activities to construct, possess and operate nuclear facilities. In our preparatory work, we assess whether applications meet our radiation safety requirements.

Nuclear power
Nuclear power currently represents approximately 30 per cent of Sweden’s national power supply. There are three nuclear power plants in the country, with a total of six reactors in operation. These NPPs are the Forsmark, Oskarshamn and Ringhals plants. The Forsmark NPP has three reactors in operation. The Oskarshamn NPP shut down two of its three reactors in 2017. The Ringhals NPP shut down...

Radiation protection for personnel
Licensees of Swedish nuclear power plants are responsible for ensuring that no one is exposed to radiation levels that cause injury. The licensees must also guarantee that all workers at the facilities are exposed to as little radiation as possible viewed over an extended period of time. This implies that the level of safety must be high enough so that no accidents occur exposing the personnel...

Decommissioning
When the operator of a nuclear facility (i.e. the licence holder) is to decommission the facility, this must be done in a way that protects people and the environment from radioactivity in the facility. The Swedish Radiation Safety Authority issues regulations governing the planning and undertaking of dismantling activities; what’s more, the Authority performs checks to ensure that the...

Physical protection
The Swedish Radiation Safety Authority imposes requirements for the physical protection of nuclear facilities and transports, for example protection against attacks and thefts of nuclear material. We monitor and check that the nuclear power industry complies with these requirements. We also help to ensure interaction between man, technology and organisation in a way so that physical...

2015:49 Technical Note, Independent Modelling of Engineered Barrier Evolution and Coupled THMC: Canister Corrosion Calculations in SR-Site
Projektets syfte Projektet syftar till att granska olika beräkningsfall för korrosion av kopparkapseln som rapporterats i SKB TR-10-66 och som sammanfattas i SKB TR-11-01. Arbetet omfattar en analys av beräkningsfall relaterade till korrosionshastigheten för intakt buffert, delvis eroderad buffert och för advektiva förhållanden i bufferten. Målsättningen...

2014:54 Technical Note, Further Modelling Comparison of Simple Reference Biosphere Models with the LDF Modelling Approach – Main Review Phase
This Technical Note describes further use of simple reference biosphere models for SSM’s review of the Landscape Dose Factor (LDF) approach adopted by SKB in the SR‑Site safety assessment for the proposed final disposal of spent nuclear fuel at the Forsmark site. Simple biosphere models for the Forsmark site under temperate climate conditions were previously developed for SSM’s review and are...

2014:08 Technical Note, Review of Long-Term Redox Evolution of Groundwater and Potential Influence of Oxygenated Glacial Meltwater in SR-Site
The Swedish Radiation Safety Authority (SSM) is reviewing an application submitted by the Swedish Nuclear Fuel and Waste Management Company (SKB) in 2011 to construct, possess, and operate a deep geologic repository for spent nuclear fuel at the Forsmark site in the municipality of Östhammar, Sweden. SKB has presented details of its long-term safety assessment, SR-Site, in a main report...

2014:35 Technical Note, Modelling comparison of alternative biosphere models with LDF models and evaluation of selected parameter values used in the biosphere dose assessment - Main review phase
This report has been prepared as part of the SSM’s Main Review Phase of SKB’s SR-Site performance assessment of the long-term safety of the KBS-3 geological disposal facility (GDF) proposed for construction at Forsmark. The review addresses the methodology employed in the dose assessment calculations of SR-Site; specifically issues of transport, accumulation and transfers of radionuclides in...

2014:58 Technical Note, Rock Mechanics - Assessing probability and extent of blind faults and fault-end growth around the KBS-3 repository at Forsmark – Main Review Phase
To get a general understanding of the stability conditions of the fault and deformation zone inventory at Forsmark a reactivation potential analysis was carried out. At present-day stress conditions the deformation zones are stable and show no large deformations or detected seismicity. Any changes in stress, and in particular increase of differential stress on deformation zones, might cause...
