2009:31 A Review of the Decommissioning Costs of the Ranstad Site
The main objective of this study has been to review the future cost to decommission and dismantling the industrial area at the site of the old uranium mine at Ranstad in Sweden. Analyses of some detailed comparative empirical information have been used in the context of preliminary “bench-marking” studies. The estimated costs for decommissioning of the old uranium mine in Ranstad have been...

2018:08 Calculated radiological consequences of applying European clearance levels to scrap metal from the decommissioning of Swedish nuclear facilities
Background Many practices involving radioactive substances generate materials with potential or known radioactive contamination. Clearance of materials means a decision that such materials can be released from regulatory control and used or disposed of without restrictions from a radiation protection point of view. According to regulations issued by the SSM, such decisions must be based on...

2021:02 On Water Induced Sensitization of Ni (Fe,Cr) alloys towards Stress Corrosion Cracking in LWR Piping from 1st Principles Modelling
SSM perspective Background In Swedish Light Water Reactors (LWR), stress corrosion cracking of reactor components and welds occurs from time to time. As the nuclear power plants are ageing, it is essential to study and further understand the mechanism for environmentally induced sensitization. Natural cracking is a phenomenon that is difficult to predict and very hard to study since it occurs...

2021:05 Cladding tube rupture under LOCA: Data and models for rupture opening size
SSM perspective Background The Swedish Radiation Safety Authority (SSM) follows the research on fuel performance closely. One aspect that is currently being studied in several research projects is the risk of release of fragmented fuel into the primary coolant in case of an accident. This risk depends on complex conditions were one is the possibility and size of a rupture of the fuel rod...

2021:07 Scenariourval i HFE-processen Arbetssätt och kriterier vid utvärdering av konstruktionens anpassning till människans förmåga
SSM perspektiv Bakgrund På en kärnteknisk anläggning genomförs under dess livstid så kallade anläggningsändringar i syfte att åtgärda identifierade brister, eller för att av andra skäl modernisera eller förbättra anläggningens konstruktion. Vid anläggningsändringar som påverkar arbetsuppgifter som har betydelse...

2021:22 Explosionslasters inverkan på reaktorinneslutningens betongdelar
SSM perspektiv Bakgrund För att en konstruktion ska kunna motstå effekterna av stora dynamiska laster, t.ex. impulslaster på grund av explosioner, behöver den ha stor energiupptagningsförmåga. Med konstruktioner menas här byggkonstruktionsdelar av armerad betong. Vid dynamiska förlopp kan materialets hållfasthet påverkas gynnsamt på grund...

2021:23 Dimensionering av nukleära byggnadskonstruktioner (DNB)
SSM perspektiv Bakgrund Strålsäkerhetsmyndigheten (SSM) och de svenska tillståndshavarna Forsmark Kraftgrupp AB, Ringhals AB, OKG Aktiebolag och Svensk Kärnbränslehantering AB, har tidigare i ett samfinansierat forskningsprojekt tagit fram anvisningar för dimensionering av nukleära byggnadskonstruktioner, DNB. Rapporten som är baserad på Eurokoderna...

2021:03 Updated radiological risk assessment for the “Radon” type surface disposal facility in Chisinau, Moldova
SSM perspective Background Bilateral cooperation between Sweden and the Republic of Moldova in nuclear and radiological safety and security has been ongoing since 2010, focusing on activities aimed at strengthening the institutional capacity of the National Agency for Regulation of Nuclear and Radiological Activities in Moldova (NARNRA) as well as infrastructure development in radioactive...

2022:08 Geophysical surveys on sub marine land- and rock slides and on alpine glaciers
SSM perspective Background The future climate evolution and the impact it might have on a repository for radioactive waste is important when assessing the long-term safety. In a project funded by SSM (Holmlund et al. 2016), bathymetric data from the Southern Quark area between Sweden and Åland, provided by the Swedish Maritime Administration, were analysed, as well as terrestrial data from...
