2009:38 Research and Development Program in Reactor Diagnostics and Monitoring with Neutron Noise Methods, Stages 14 and 15
constitutes Stages 14 and 15 of a long-term research and development program concerning the development of diagnostics and monitoring methods for nuclear reactors. Stage 14 was a full one-year project, whereas ... whereas Stage 15 consisted of a half-year project. Results up to Stage 13 were reported in SKI reports, as listed below and in the Summary. The results have also been published in international journals and...

2017:13 Monte Carlo patient-specific pre-treatment QA system for volumetric modulated arc therapy
Background The clinical use of volumetric modulated arc therapy (VMAT) has augmented rapidly since it became commercially available. As a result, the need for comprehensive quality assurance (QA) has increased ... increased. Current practices in Sweden normally compare the delivered dose with the planned dose based on measurements with different methods, for instance: portal dosimetry, point dose verification and/or...

2022:14 Weld residual stress and strain measurements on a mock-up with single layer strip cladding common in reactor pressure vessels
SSM perspektiv Bakgrund Reaktortryckkärl tillverkas vanligtvis av låglegerade ferritiska stål som på insidan beläggs med ett eller flera lager av rostfritt stål, ... Resultaten från mätningarna visade på dragspänningar i nivå med sträckgränsen i pläteringen och cirka 30 mm in i grundmaterialet. Efter värmebehandling konstaterades kraftigt reducerade spänningar i grundmaterialet...

2019:26 Analysis of trends in brain tumour incidence in Sweden
perspective Background In the past few years, a discussion has been ongoing in both the research community and the media as to whether exposure to radiowaves from the use of mobile phones has an impact on ... incidence of brain tumours in the general population. Ever since the introduction of mobile phones in the 1980s, their use has increased dramatically and has now spread to almost all parts of the world...

2012:52 Technical Note, Shear movement of near-field rock due to large earthquakes
concentrates on the possible impact of large earthquakes on the shear deformation of large fractures in the repository volume. For this purpose a general review of some of SKB‘s top-level reports was carried ... out. The reports draw a generally consistent and to a considerable extend comprehensive picture of the potential impact on the repository integrity in case of the unlikely event of a large earthquake close...

2015:04 DiD-PSA: Development of a Framework for Evaluation of the Defence-in-Depth with PSA
interpretation of the definitions of Defence in Depth given by IAEA which outline a framework to meet PSA. For each level of defence and combinations of levels, methods to give estimates from a PSA perspective ... the discussion of the basic definitions and the basis for defence-in-depth, as defined by IAEA, leading to somewhat modified and further developed definitions that support the link to a developed PSA.

2017:25 Evaluation of weld fatigue reduction in austenitic stainless steel pipe components
Background The performed investigation is a continuation of the work performed in SSM 2015:38 where fatigue tests were performed on pressurized welded austenitic stainless steel piping components. The ... to a realistic variable amplitude loading with mainly reversed bending deformation and particular focus on high cycle fatigue. The previous fatigue results were quite dependent on the estimation of the...

2007:10 Radiological consequences of radionuclide releases to sewage systems from hospitals in Sweden
sewers originating from hospitals, mainly in the form of the excretion of patients treated with radioisotopes for diagnostic or therapeutic purposes. Assessments of doses to the public, including sewage workers ... discharges are performed. Doses are compared against the exemption level of 10 μSv/a and the dose constraint of 100 μSv/a. As a basis for the dose assessments, information on the use of radionuclides in Swedish...
