[en] Sweden has made a spectacular comeback in academic nuclear education. About 20 years ago, the field was close to extinction at Swedish universities, whereas today more than 20 permanent professors are active, with an average age below 50 years. This change is the result of a close collaboration between industry, regulator and universities. (orig.)
[en] This study is positioned in a multidisciplinary research field addressing questions of innovation, foresight, risk perception, regulation, and the role of stakeholder experts as regards nanomaterials and nanotechnology. Nanotechnology is an innovative scientific field with many potential societal benefits but also high uncertainty about risks to human health and the environment. This study is based on a survey distributed to a sample of 237 expert stakeholders in Sweden working in the field of nanotechnology innovation and regulation. The sample comprises experts in both industry and government organizations. The paper explores the expert’s assessment of benefits, risks, and their views of nanotechnology regulation. The experts generally agreed on the need for further regulation of nanotechnology, although they differed in their support for different regulatory measures. Support for government regulation was increased by greater perceived risk and by ethical concerns, while perceived benefit decreased support for government regulation. If nanotechnology was important for the respondent’s organization of affiliation, support for government regulation decreased. Experts in government organizations were more in favor of stronger government regulation, perceived higher risks, and were more concerned about the ethical implications of nanotechnology than were the industry experts. While previous research has discussed views of experts, as well as comparing the attitudes of the general public with experts, this study contributes to the field by analyzing and identifying differences between industry experts and experts working in government.
[en] The Swedish Air Force flight training has an approach which is unusual compared to how other military flying schools conduct their training. In the past, the selection and training of new pilots was conducted in a more classic way, an approach where sometimes only 25% of the students made it through the programme to become pilots. A thorough re-design of the training philosophy and programme, has led to a drastic improvement and a success rate of 95%. The training philosophy is based on the idea that you do not learn when you are forced and stressed. The training environment has a very flat and practically non-existent hierarchy. The training is based on a solid belief that by using pedagogics, mental training and creating a stress-free environment where no competition among students exists, practically all students should be able to succeed. One key element to this approach is the flight instructor. The instructor pilot needs to have the ability to adapt to the students' personality and learning style. The presentation will describe in more detail the training philosophy based on a flexible training system to prepare the students to handle pressure without stress in a high risk environment.

[en] Highlights: • We take an energy service company perspective to analyse energy efficiency barriers. • Actor-barrier relationships were identified using a business ecosystem approach. • Main barriers relate to technical skills, disinterest and non-functional regulation. • Intermediaries can play a greater role in helping actors to overcome the barriers. • More active communication between the policy-makers and implementers is needed. - Abstract: Energy inefficiency in the building stock is a substantial contributor to climate change. Integrated energy service companies (IESCs) have a potentially important role in improving energy efficiency. This paper presents a qualitative analysis of the energy efficiency barriers in the Finnish building sector based on data from interviews with twelve IESCs. Taking a novel supply side perspective, we place IESCs at the centre of the emerging energy services business ecosystem to identify the barriers and hindering factors (real world illustrations of barriers). From this perspective, we also examine cause-effect relationships between the hindering factors and the actors. Hindering factors, reported by IESCs, were categorised under a revised barrier taxonomy consisting of economic market failures and economic market, behavioural, organisational and institutional barriers. The most salient hindering factors—lack of technical skills, disinterest in energy efficiency improvements and non-functional regulation—were analysed with respect to ecosystem actors causing and affected by these factors. Public actors have a key role in overcoming these barriers, for instance, by creating new possibilities for entrants to take part in decision-making, increasing the functionality and practicality of policies and by providing up-to date energy efficiency information.
[en] With the aim of understanding the nature of mining-induced seismicity, microseismic activity in the deep metal mine of Garpenberg (Sweden) has been recorded during 2 years of excavations. The studied area of the mine is operated using sublevel stoping method with backfilling, between depths of around 1000 and 1300 meters. Spatiotemporal analysis of microseismic activity is presented and correlated with the occurrence of mining blasts. A clear dependence is observed between blasts and seismic sequences, even if the rock mass response to mining appears to be very variable across space and time. Two main clusters are observed: one located in the major production area (Central Cluster), while the second (Right Cluster) is located at some distance from the excavations, in a zone characterized by a heterogeneous distribution of weak materials and stiff rock masses. By analyzing seismic source parameters, we demonstrate that the two clusters are characterized by different dynamics. In addition, we show how Right Cluster events are mainly controlled by geological heterogeneities, which impose high stress concentrations in the stiff rock masses surrounding weak lenses. High apparent stresses and corner frequencies associated with the Right Cluster events agree with our proposed model. This suggests elevated stresses in the seismic source region and small source dimensions; indeed, fractures cannot propagate along great distances due to the presence of weak lenses interbedded with the breaking stiff rock mass.
[en] The expected increase in precipitation and temperature in Scandinavia, and especially short-time heavy precipitation, will increase the frequency of flooding. Urban areas are the most vulnerable, and specifically, the road infrastructure. The accumulation of large volumes of water and sediments on road-stream intersections gets severe consequences for the road drainage structures. This study integrates the spatial and temporal soil moisture properties into the research about flood prediction methods by a case study of two areas in Sweden, Västra Götaland and Värmland, which was affected by severe flooding in August 2014. Soil moisture data are derived from remote-sensing techniques, with a focus on the soil moisture-specific satellites ASCAT and SMOS. Furthermore, several physical catchments descriptors (PCDs) are analyzed and the result shows that larger slopes and drainage density, in general, mean a higher risk of flooding. The precipitation is the same; however, it can be concluded that more precipitation in most cases gives higher soil moisture values. The lack, or the dimensioning, of road drainage structures seems to have a large impact on the flood risk as more sediment and water can be accumulated at the road-stream intersection. The results show that the method implementing soil moisture satellite data is promising for improving the reliability of flooding.
[en] In 2012, Posiva Oy submitted a construction licence application for a spent nuclear fuel disposal facility to be constructed at Olkiluoto, Finland. A safety case (TURVA-2012) was compiled to support the licence application. The disposal concept is based on the KBS-3 method. The reference design is the KBS-3V design, where the spent nuclear fuel canisters are emplaced individually in vertical deposition holes positioned along deposition tunnels. Posiva Oy is also studying, in collaboration with its Swedish counterpart SKB, an alternative design variant, KBS-3H, where the canisters are emplaced horizontally in 100−300 m long deposition drifts. This design variant was also included in the application as a potential alternative. In order to compare these two alternatives, a safety case, following Finnish regulatory requirements, is being produced for the KBS-3H design. The main objective is to determine whether KBS-3H can be shown to fulfil the longterm safety requirements with the same level of confidence as for KBS-3V. To this end, long-term safety related requirements specific to the KBS-3H design are being defined following Posiva’s requirements management system (VAHA). VAHA includes five levels of requirements spanning from legal and stakeholders’ requirements (level 1) to system requirements (level 2), performance targets and target properties (level 3), design requirements (level 4) and finally design specifications (level 5). The level 1 requirements, since they stem from laws and regulations, are identical for both designs. At lower levels, the differences in the designs have an increasing effect on the details of the requirements and design specifications. The set of release barriers is partly different in the two designs, as are the types and dimensions of the emplacement areas and their construction methods. The development of the KBS-3H-specific requirements starts by defining the barriers of the KBS-3H design and assigning safety functions for the individual barriers. The safety functions will then give rise to performance targets, and subsequently to the more detailed requirements and specifications at lower levels. The safety case for KBS-3H will then evaluate whether the horizontal design fulfils these requirements. The requirement definition includes interesting aspects related to the fact that KBS-3H has been developed over decades in parallel to the reference design KBS-3V, and it includes several novel solutions and unique components not included in KBS-3V. The iteration among requirements formulation, safety assessment and design development is particularly visible in this project. (author)
