Population supports the need for switching to green power, which is most often understood to mean the use of solar and wind energy. It would be however a mistake to think that solar and wind power plants will solve in full the problem of uninterrupted power supply for all sectors of economy due to the instability of generation modes and the scale of such energy production. Experts suggest that the only possible way to address global energy and environmental issues is further evolution of nuclear power. Nuclear power is not listed explicitly as a national priority project but it is a component of the Science national project and is expected to contribute to the implementation of the Ecology, Education, and International Cooperation and Export projects. In the context of the Ecology project, nuclear power is capable to play a key role in preventing environmental contamination. In the framework of the International Cooperation and Export project, it is possible to export high-technology fast neutron reactors. The experience of interaction with the interested public, and the developed and implemented occupational training programs will provide for the shaping of radiological literacy among young people as part of the Education project.

Teachers Attitudes

There is not a common attitude in a society for socio-scientific issues (SSI) such as whether to use nuclear power plants for energy production. Within this respect, the aim of the research is to examine pre-service science teachers’ and pre-service social studies teachers’ attitudes toward SSI and to reveal their views about setting up nuclear power plants in their country. The participant of research is 120 pre-service teachers. Firstly, Attitudes toward Socio-scientific Issues Scale (ATSIS) was implemented and then, focus group discussions were done with five students from each department separately so as to understand their views about nuclear power plants. Findings revealed that whereas pre-service teachers are eager to learn more about SSI, they have anxiety about it due to religion, moral and ethical perspectives. In addition, whereas both groups of pre-service teachers have some common views about nuclear power plants, pre-service science teachers do not have more positive views about having nuclear power plants in their country. Key words: attitude towards socio-scientific issues, focus group discussion, pre-service teachers, nuclear energy.

Abstract. Turbines in wind power plants experience significant power losses when wakes from upstream turbines affect the energy production of downstream turbines. A promising plant-level control strategy to reduce these losses is wake steering, where upstream turbines are yawed to direct wakes away from downstream turbines. However, there are significant uncertain- ties in many aspects of the wake steering problem. For example, in-field sensors do not give perfect information and inflow to the plant is complex and difficult to forecast with available information, even over short time periods. Here, we formulate and solve an optimization under uncertainty (OUU) problem for determining optimal plant-level wake steering strategies in the presence of uncorrelated uncertainties in the direction, speed, turbulence intensity, and shear of the incoming wind, as well as in turbine yaw positions. The OUU wake steering strategy is first examined for a two-turbine test case to explore the impacts of different types of inflow uncertainties, and is then demonstrated for a more realistic 11-turbine wind power plant. Of the sources of uncertainty considered, we find that wake steering strategies are most sensitive to uncertainties in the wind speed and direction. The OUU strategy also tends to favor smaller yaw angles when maximizing expected power production. Ultimately, the plant-level wake steering strategy formulated using the OUU approach yields 0.48 % more expected annual energy production than the deterministic strategy when considering stochastic inputs. Thus, not only does the present OUU strategy produce more power in realistic conditions, it also reduces risk by prescribing strategies that call for less extreme yaw angles.

The expansion of wind turbines plays a significant role in developing the ability of a country like Sweden to achieve climate-neutral energy production without relying on nuclear power plants. Wind-turbine energy production is expected to grow in the coming decades. Conflicts may arise between, on the one hand, the government and the energy authority, and, on the other hand, municipalities and property owners, especially if this expansion affects other economic activities, such as tourism and reindeer husbandry, or property values. This report aims to analyse the negative capitalization of wind turbines on property values in Sweden over the last ten years. Our conclusions clearly show a relatively significant capitalization and that this capitalization is relatively local, within eight kilometers of the wind power plant. Large wind turbines, or larger clusters of wind turbines in wind farms, impose a greater socio-economic cost on lower value properties.
