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...

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...

New wide call to strengthen research in nuclear power, waste management, radiation protection and nuclear non-proliferation
The Swedish Radiation Safety Authority is launching a wide research call covering four areas within radiation safety, including skills supply, nuclear non-proliferation, and the final disposal of nuclear waste. In total, the authority plans to allocate SEK 81 million for research during the period 2026–2031. International institutions are also eligible to apply for funding from one of the...

2024:14 Residual stress distributions in nickel-based dissimilar metal pipe welds
SSM perspective This report concerns a study which has been conducted for the Swedish Radiation Safety Authority, SSM. The conclusions and viewpoints presented in the report are those of the author/authors and do not necessarily coincide with those of the SSM. Abstract It is common for nickel-base materials to be used as filler metals in the welding of dissimilar metal welds. Dissimilar metal...

2025:01 Safety Concept Evaluation with Failure Tolerance Analysis
SSM perspective Background One of the most important design principles to achieve high safety function dependability is the use of redundancy to be single-fault tolerant. In turn, redundancies become effective by applying additional design principles such as physical and functional separation and diversity. License holders of nuclear power reactors must demonstrate that requirements are met,...

IAEA IRRS-mission report to Sweden published
The International Atomic Energy Agency, IAEA, has reviewed Sweden’s framework for nuclear safety and radiation protection, the so-called IRRS review (Integrated Regulatory Review Service). The review is carried out every ten years by a group of international experts led by a team from the IAEA. Sweden’s second full-scope IRRS-review was carried out 14 – 25 November 2022. The report has now...

2006:15e Safety and Radiation Protection at Swedish Nuclear Power Plants 2005
The safety philosophy upon which the Swedish Nuclear Power Inspectorate’s (SKI) supervisory and regulatory activities are based assume that multiple physical barriers will exist and that a plant-specific defence-in-depth system will be implemented at each plant and that the licensee bears the undivided responsibility for safety. The physical barriers are situated between the radioactive...

2005:32e Safety and Radiation Protection at Swedish Nuclear Power Plants 2004
The safety philosophy upon which the Swedish Nuclear Power Inspectorate’s (SKI) supervisory and regulatory activities are based assume that multiple physical barriers will exist and that a plant-specific defence-in-depth approach will be implemented at each plant. The physical barriers are situated between the radioactive material and the plant personnel and surroundings. In the case of...
