Kärnkraft - en demokratifråga? : En studie om lärares kärnkraftsundervisning och ett rollspel i förhållande till demokratiuppdraget.
Kärnkraftsfrågan har sedan åttiotalet varit omdebatterad i Sverige och under 2011 harfrågan blivit högaktuell efter kärnkraftsolyckan i Fukushima. Eftersomdemokratibegreppet utgör grunden i den svenska skolan är det relevant att ifrågasättahur olika former av kärnkraftsundervisning står i relation till demokratiuppdraget. Syftetmed studien var att undersöka hur ett antal lärare beskriver sin kärnkraftsundervisning iförhållande till demokratiuppdraget, därutöver att konstruera ett rollspel om kärnkraftutifrån lärarnas tankar och demokratiuppdraget. Första delen av studien bygger påintervjuer med högstadielärare i de naturorienterade ämnena. Respondenterna fickbeskriva sin kärnkraftsundervisning, vilken sedan utvärderades i förhållande till skolansdemokratiuppdrag.

Title: Every second week. A study on how co-parented children do family. The aim of the study is to explore children?s day-to-day experiences of co-parenting. It focuses on how the children actively participate in the process of shaping family life and their own childhoods in the context of family change.
Småskalig vattenkraft :
Small hydropower plants have been an important source for electricity for many years.
During the 70?s the general thought was that Nuclear was the future. Around 2000 small
waterpower plants were shut down. It wasn?t profitable to invest in.
Val av överlastskydd för elektriska ventilmanöverdon på kärnkraftverket i Forsmark
At Nuclear power plants, electrical valve actuators are important for ensuring that the reactor core is water covered and the pressure in the reactor tank and containment is limited. The electrical actuators are provided with overload protection in case of drawing higher current then the motors are rated for. When safety manoeuvres are needed, the overload protection must not trig and cause the valve to stop before completing the manoeuvre. Analyses have showed that the current settings of the overload protection may cause an illegitimate trig at the worst theoretically possible accident. A new method has been developed with conservative assumptions and applies overload protections for all electrical valve actuators at the three reactors in Forsmark..
En jämförelse av stickprovsmetoder vid mätning av radioaktivetet på en yta
This study compares the sample variance of the mean in a simple random sample (SRS) and a systematic sample from a surface. The study also compares the prediction error variance in a SRS and systematic sample from a random field. Recommendations are presented on which method to use in the clearance and exemption process in the Nuclear industry. The results indicate that quadratic systematic sampling outperformed SRS in most instances and proved to be especially efficient in the presence of a long-ranged covariance function and high sampling intensity (i.e. short distances between observations).
?Förhoppningsvis är man två? : En studie över hur 18-åringar i en mindre stad i Sverige resonerar kring kön, kropp och sexualitet
The essay is about how teenagers around 18 years of age in a small town in Sweden talk about gender, body and sexuality. The study is based on two focus group interviews with five boys and four girls. We have then thematized and analyzed the material with queer theory.The results show how young people see heterosexuality as something 'natural' and gender as biologically determined. The teenagers are critical towards anything that deviates from the traditional Nuclear family consisting of mother, father and children. Norms are created in their speech as some of them acts as so called "border guards" for these norms.
Rolf Edberg : En studie av ett miljöfilosofiskt författarskap
In this essay I have tried to present the ideas and thoughts of the Swedish author Rolf Edberg (1912-1997), journalist, ambassador and county governor. By many regarded as an environment philosopher and the introducer of deep ecology into Sweden. The essay emphasizes Edberg as a modern renaissance man of important knowledge with a rhetorical force to present and generalize the problems the planet Earth is meeting. The paper compares him with Henry Thoreau but also finds a close but perhaps unintended relationship with the German philosopher Ernst Haeckel although Edberg himself claimed to be a Darwinist at heart.The essay stresses on four characteristic features in his authorship namely 1) a holistic view of nature and man, rejecting dualism for monism; 2) a cosmic relationship within the whole universe and also between organic and inorganic matter; 3) the planet Earth is in a crisis due to an uneven and unjust distribution of the resources of the Earth, the Nuclear weapon threat and the overpopulation; 4) the evolution and not the religion has the answer to our existential questions..
Visualiseringsverktyg för Sykedjor
This thesis has been done in order to ease the process of drawing schematics ofelectrical wiring. The need arose after demand from the government due to a seriesof incidents that took place during the revision of the Nuclear power plant in year2009.The task of the project has been to create a computer program that can generate agraphical representation of the electrical components relations. The basis for theprogram has been an example of how the client wants the graphical representation tolook. During the course of the project weekly meetings have occured in which theclient has reviewed the work.The result of the project is a program written in Visual Basic Applications that can berun in Microsoft Excel. The program is capable of generating graphics for a majority ofthe cases.
Att arbeta med ständig osäkerhet : En studie av High Reliability Organization
There are certain organizations that manage to handle risk in such a successful way that they almost stay error-free, in spite of the fact that they daily face the risks of accidents. These organizations are usually given the name High Reliability Organizations (HRO). While the most common example is that of a Nuclear plant the variety of what organizations can fit into the category is extensive.The purpose of this study is to describe safety culture and theories about HRO and how these can be found in practise within an organization.This qualitative research uses influences of ethnography in its method. The ethnographical approach was picked due to the field of the study and the cultural context in which it is set.The results of the study identify a number of elements sorted into four themes. These themes are deemed compatible or non-compatible with relevant existing theories.
Den iranska nationen - Vi och de i kärnkraftskonflikten
Den här uppsatsens syfte är att undersöka vilken iransk identitet som skapas av landets ledning och på så sätt bidra till förståelsen av den iranska politiken. Frågeställningen är: "Hur ser den identitet ut som konstrueras av det iranska ledarskapet genom deras offentliga tal gällande kärnkraftsfrågan?". Frågan besvaras utifrån ett konstruktivistiskt perspektiv och med Laclaus och Mouffes diskursteori som metod. Analysen består av en kartläggning av ekvivalenskedjorna för Vi, "Den iranska nationen", och De Andra, "Irans Fiender".
Icke-linjära modelleringsteknikerav förspänd betongkonstruktion : Reaktorinneslutningen på Forsmark 3
A new material model, for the FE-program ADINA, has been verified against twoexperiments. One unreinforced concrete beam and one reinforced concrete beam.The model, DF-concrete, has the possibility to estimate true concrete. However theresults indicate that in order to be sure that the estimations are true, there ought tobe data from the true concrete to verify against.Two FE-models have simulated the behavior of a ring-shaped part of the Nuclearcontainment vessel. The results from the first, frictionless, model agree with similarsimulations and hand calculations for high pressures in the containment vessel. Thesimulations of the Nuclear containment vessel show cracking in the concrete after10-11 bars of over pressurization.
U-137 svenskt politiskt och militärt agerande under kris
This bachelor thesis deal with the Soviet submarine U-137 and it's grounding inthe Swedish archipelago outside the city of Karlskrona and one of Sweden?slargest naval-bases. The actions that took place in October 1981 were specialbecause of the clear violation of Swedish territory. When the Swedish authoritieslater suspect Nuclear armament onboard the crisis gets worse. In the thesis wehave examined the Swedish politicians and military and their behaviour duringthe crisis.
Sjöingenjör : Möjligheternas Yrke
Kärnkraften ser vi som ett miljövänligt och bra alternativ för framtiden. Därför kändes det intressant att undersöka om vi som blivande sjöingenjörer har en framtid där efter våran karriär till sjöss. Syftet med detta arbete är att få ökad insikt om vilka teoretiska kunskaper, praktiska och personliga egenskaper som gör sjöingenjören attraktiv i ledande befattningar vid kärnkraftsverk. Datainsamlingen skedde med hjälp av en enkätundersökning och en intervju. Undersökningen skickades ut till Sveriges samtliga kärnkraftverk och intervjun gjordes med en anställd på ett utav dem.

Diplomati med klyvbar kärna - en kvalitativ studie av den ryska diplomatins grundval
AbstractThe purpose of this thesis is to analyse the basis of Russian diplomacy, and by doing that develop the analytical instruments available, in order to improve the comprehension between the parties in negotiations. Descriptions of the national characteristics of Soviet and Russian diplomacy are made by an analysis of memoairs and other examinations of their negotiating behaviour. To ensure the result of the characteristics two case studies of the non-Nuclear proliferation negotiations are made, followed by a comparation between the Soviet and Russian diplomacy. From these results, I analyse the groundworks of russian diplomacy, using three theories about how ideology, national identity and prevailing self-image can affect the national negotiating behaviour. The results show that there have been changes in only some parts of the negotiating behaviour and that there is a need for all three theories to explain different parts of the complex system of Russian diplomacy which is based on the plurality of culture, ideology, language, ideology and history..
