Energiewendes påverkan på det nordiska kraftsystemet

Both the German and the Nordic power markets are seeing dramatically changed conditions due to an ongoing process of expanding the share of renewable production in the systems. For the German part this comes from heavy subsidies which have led to an explosive development in installed capacity of photovoltaic and wind based production. After the Fukushima incident it has been decided to shut down all Germanys nuclear plants. This capacity drop is however not of the same magnitude as the increase in renewables, but will impact the stability of the power system. The Nordic power system which already has a surplus of power sees an even further increase, coming mainly from construction of new nuclear plants in Finland and a general increase in wind farms.

Säkerhetsanalys av brandbekämpning i kritiska utrymmen på Forsmark 1

In order to maintain a high safety level at a Nuclear power plant it is important not only to measure the reliability of the components and systems of the plant, but also to investigate how the plant responds to human actions. One of the most hazardous situations in managing a power plant is fire occurring in critical areas. This study concerns the prospect of the local fire brigade to suppress a fire that has started in one of the most critical rooms for maintaining high reactor safety. The model created gives an indication on the possibilities of succeeding in suppressing a fire. In order to get a more reliable fire fighting the following advice are given:- Let the fire brigade go rounds in the plant together with the personnel, during which recommended fire suppressing methods are determined to avoid long preparation time in an actual situation.- Prepare rooms with two subsystems to make them partly with no voltage.- Give the fire brigade better feedback from actual events on Nuclear power plants.- Education and training in suppressing fires in electrical equipment.The probabilistic safety assessment strives to be as realistic as possible.

Utveckling av ett användbart IT-stöd : för att stödja operativa arbetsrutiner

Nuclear power production carries potential risks both for the environment and for the work force. Different safety measures are employed and they stem from local rules as well as from regulatory authorities. This work describes the development of a safety promoting tool at Forsmark Power Plant, one of Sweden?s three Nuclear power plants. We describe the development of a computer based system for Pre-Job Briefing and Post-Job Debriefing.

Föräldraskap, kön och jämställdhet i Maria Svelands Bitterfittan

The aim of this Masters´ thesis is to examine parenthood, gender and equality. The analysis is based on the novel Bitterfittan. The primary theoretical points of departure are Judith Butler?s theory about doing gender and Yvonne Hirdman?s theory about the gender system, the hierarchical order and the separation of the sexes. I use Lisbeth Bekkengen?s thesis in which the nuclear family is seen as an institution which is upheld by two structures; that is the social relationships man-woman and parent-child, and also by two discourses; on the one hand a notion that fathers and mothers are principally different and on the other hand the child focus.

Olika kön - olika bedömningar? : En kvalitativ studie baserad på socialarbetares bedömningar kring ett enskilt fall

This qualitative study aims to highlight if there are any gender difference in social workers reasoning about a particular case. To achieve a deeper understanding we had to explain and understand our respondent?s answers, primarily from a gender perspective, but also from a power perspective. Our questions were: how does social worker reasoning about a particular case? How can we understand the social workers answer from a gender- and power perspective? The method consisted of a construct case and of semi-structured interviews.

Svenska kärnvapenprogrammet under Kalla kriget : En studie av den internationella arena som påverkade uppstartandet och nedläggandet av Sveriges kärnvapenprogram

The purpose of this paper is to investigate possible reasons Sweden might have had to motivate the start and end of its nuclear program during the Cold war. This investigation will be conducted using a qualitative research method and making a comparison between the theories realism and liberalism?s ability to explain the decisions. The question this paper is based upon is as follows: Can Sweden?s creating and shutting down of a nuclear weapons program during the Cold war be explained by the international events and actions that were taking place during this time period? The result consists of liberalism pointing out several failures on the international level that might explain the cynical decision from Sweden to create the nuclear weapons. Realism considers the decision to make perfect sense at this point in time, to protect Sweden on the anarchy that was going on at that time according to this theory.The ending of the nuclear weapons program is being explained largely by the rise of the MAD-concept which renders the acute need of nuclear weapons in Sweden void.  Liberalism on the other hand considers this a logic step due to the better established UN that is playing a larger role now than in the 1940s. In conclusion, realism does a better job explaining the start of the nuclear weapons program, while liberalism explains the end of it more efficiently. The contribution this thesis has to the research of political science can be seen mainly in three areas.

Att göra mål : en jämförande studie mellan Flygvapnets och Forsmarks sätt att sätta upp mål för säkerhetsarbete

I chose to study how the Swedish Air force carries out their work with setting goals for their work to improve flight safety and compare this with how the Swedish Nuclear power plant Forsmark performs their work with improving nuclear safety. The study showed that both organisations have a lot to improve on in their ways of how to work. Especially when it comes to engaging the employees in the process, both in letting the employees be a part of coming up with areas to work on and in letting the employees evaluate which progress that has been made. It also showed that both organisations need to improve their methods for evaluating the work that has been done. This is especially important for the Air Force which evaluates on many levels and locations and did not have a set standard for how to conduct the evaluation.

Politiska ideal kommer och går, men kärnfamiljen består : en diskursanalys av riksdagsdebatten om vårdnadsbidraget 2007/2008

This thesis takes as its point of departure the Swedish governmental family policy and the debate on the proposed reform ?vårdnadsbidraget?. The supporters of the reform present it as something that will increase the freedom of choice for families and benefit the children, whereas the opponents warn for decreased equality and a return to the male breadwinner-model.From a constructivist perspective, language is closely related to power through defining and ascribing meaning to reality. By applying a feminist political theory on the debate within the Swedish national parliament 2007/2008 and conducting a discourse analysis, the aim of this paper is to analyse which concepts are used and how they construct to what makes a family within the political debate ? is there any difference or similarity between the view of the opponents and the supporters of ?vårdnadsbidraget??The main conclusion of this paper is that even though the political ideal and rhetorical concepts differ between the supporters and the opponents, they still constitute the heterosexual nuclear family as an obvious norm in family politics.

Vindkraftetablering och uranborrning i Dalfors-Dalarna; Acceptans bland närboende

The dependency of fossil fuels has to decrease in order to reduce emissions of green house gases. Wind turbines generate electricity with low environmental impact, but the local opinion in Sweden is sometimes an obstacle to new developments. The acceptance of Nuclear power increases at the same time. Mining uranium is once again on the agenda and prospectors are currently drilling for uranium. This cross-sectional study deals with acceptance of wind farms and uranium drilling.

Den svenska kärnkraftspolitiken : En processpårande fallstudie av svensk kärnkraftspolitik

This study deals with Swedish nuclear-energy politics from 1980 to 2006. The purpose is to trace and to explain change and stability in three political parties? rhetoric concerning the phase-out of Swedish nuclear-energy and the Swedish government?s nuclear politics. Two hypotheses based on path dependency theory are tested to analyze if rhetoric and politics are developing in separate directions. The first hypothesis is based on the idea that earlier promises from the political parties affect what promises they can make later on.

Trycksättning och dimensionering av brandhiss för berganläggning

This thesis deals with the design of a combinated rescue-, personal-, and firefighting elevator for a nuclear waste storage facility to be constructed by the client SKB, Svensk Kärnbränslehantering AB. SKB:s mission is to dispose of all nuclear waste from all swedish Nuclear power plants. The storage facility will be built in the rock 450 m under the surface and will consist of several kilometers of tunnel where capsules containing the nuclear waste will be placed. It will also hold a central area which contains spaces necessary for the operation and construction of the facility, such as elevator hall, storage hall etc. The facility will have two ways of access: a vehicle ramp and an elevator shaft.
