• 2016:31 Measures and method characteristics for early evaluation of safe operation in nuclear power plant control room systems

  there is a need to develop evaluation methods in parallel with the development of control rooms in conjunction with construction modifications and other changes. This includes more indepth analysis of the methods ... conventional methods of evaluating control rooms and issues need to be reexamined. SSM has previously provided funding for several individual research projects regarding evaluation of control rooms. Both...

• 2016:26 Ensemble for deterministic sampling with positive weights

  The aim of this project is to find a reliable method for determining an ensemble for Deterministic Sampling with only positive weights. This report is intended to work as a presentation of the project ... as well as to work as a beginner’s guide to DS. In the report several methods for generating DS ensembles are presented, which can encode up to four moments and represent any kind of probability distribution...

• 2016:01 Literature Study on Sparse Channel Interpretation and Modeling

  Channelling has been observed in laboratory and field experiments at various scales. However, it is still an open research issue whether a sparse channel network is likely to be a better model than the fracture ... the flow system in fractured rocks. The present report presents a literature study to bring together information useful for addressing this issue. Several key questions are discussed, namely (a) what are...

• 2016:27 Validation of fatigue fracture mechanics approaches

  Background In a previous study (SSM research report 2015:38) fatigue experiments were performed on welded austenitic stainless steel piping components. The fatigue experiments offer an opportunity to evaluate ... evaluate fatigue flaw tolerance assessments used in industry, which are based on the fracture mechanical approach implemented in ProSACC. Objective The present study aims to validate the used fatigue flaw...

• 2016:30 Measurement of Parameter Values for Predicting Corrosion Phenomena on Copper in Swedish HLNW Repositories

  for the isolation of high-level nuclear waste in Sweden, has been studied in simulated, sulphide- and chloride containing granitic rock groundwater and the data are interpreted in terms of the Point Defect ... The results indicated that a sulphide barrier layer forms on the copper surface, and that chloride ion can induce passivity breakdown, and hence induce the development of localized corrosion damage (LCD)...

• 2016:14 Radiological examinations of children: a study of method options

  Radiation Safety Authority, SSM, decided in 2011 to investigate the justification of the use of diagnostic computed tomography (CT) for children up to fifteen years of age. The reason is the fact that CT is ... number of CT examinations increased by 200%, and during the last 16 years, by 320%. In the present study, 3,149 CT, magnetic resonance imaging (MRI) and ultrasound (US)examinations in Sweden of children...
