2024:10 Computational analysis of high-burnup fuel rod behaviour in PWR large-break LOCA
SSM perspective Background Quantum Technologies AB (QT) has for many years developed computational models for the thermomechanical behaviour of nuclear fuel in events such as LOCA and RIA. The research projects have been based on evaluations of tests on nuclear fuel in Halden Reactor Project (HRP) and Studsvik Cladding Integrity Project (SCIP). The models developed by QT enable analyses and...

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,...

2025:03 APRI-11 – Final Report
SSM perspective Background The Swedish Radiation Safety Authority together with the Swedish Power companies operating nuclear power reactors in Sweden have since early 1990’s provided financial support for severe accident research at KTH and Chalmers. The research was initiated almost directly after the installation of severe accident management system and strategy, as filtered containment...

2026:06 A Human Reliability Analysis (HRA) Taxonomy for Small Modular Reactors (SMR) – Part 1 of 2: Mapping the SMR landscape
SSM perspective Background Small Modular Reactors (SMRs) are typically presented as a solution for safe and reliable energy, requiring less time to construct than the traditional large reactors. The inherent safety features, higher levels of automation and increased reliance on passive safety are often held as reasons for fewer operators being needed in the daily operations and for handling...

2026:08e Food contamination from fallout following a nuclear explosion
Summary After a nuclear explosion, small particles may be dispersed as fallout over large areas and cause radioactive ground deposition. Radiation doses may be received from the fallout in several ways. One such exposure pathway is the ingestion of foodstuffs contaminated by the fallout, either directly or through agricultural production in areas with ground deposition. The Swedish Radiation...

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...

Microwave drying
Microwave drying is becoming more and more common for repairs of moisture and water damage in apartment buildings. It is much faster to dry moist flooring and walls made out of concrete by using microwaves than compared with ordinary construction fans. If microwaves in connection with microwave drying are used incorrectly, they may cause injury. This is why the Swedish Radiation Safety...
