Kärnkraftens värde i framtiden : en jämförelse med kraftvärmeteknologi från biobränsle

The debate on the future of Nuclear power in Sweden has increased with the discussion on global warming. The uncertainty of fossil fuel- and carbonprices the latest years has aroused considerable interest in Nuclear from power companies, industry and politicians. Nuclear power plants have negligible CO2 emissions and are not directly affected by increased price of emission rights and fossil fuels. The future power production needs to reduce its emissions of greenhouse gases to become sustainable. The purpose of this study is to examine the value for power producers to have the option to invest in Nuclear power and how a Nuclear power venture would affect future electricity prices. The study uses two methods, a traditional cash flow model and real option analysis, to estimate the value of Nuclear power.

Does nuclear power plants affect house prices? : a hedonic price model of Forsmark nuclear power plant

Nuclear power plants existences have been well debated since the 70s (Swedish radiation safety authority, 2014). Accidents, risk and presence connected to Nuclear power plants have been part of many studies around the world. Recent studies have shown a connection between prices of houses and the distance and presence of Nuclear power plant in a surronding area of the house. This paper uses Hedonic price modelling to investigate the willingness to pay for an increased distance to the Swedish Nuclear power plant, Forsmark. For the dependent variable selling price was used and the independent variables were number of rooms, living area, other area, lot size, selling year, building year and distance to Forsmark.

Den svenska kärnkraftsdebatten i skuggan av Fukushima : En studie i hur svenska kärnkraftsförespråkare i maktposition använder argumentation och auktoritet

Aim: The nuclear accident in Fukushima, Japan, raised global criticism against Nuclear power. In Sweden, the criticism has not been very visible and the government now allows a renewal of the Nuclear power plants. The purpose with the study is to have a closer look on how Swedes in position of power motivate their positive attitude to Nuclear power and how they conduct themselves to each other and to their opponents. The rhetorical perspective will be in focus for the analysing.Method: Four different artifacts represented by Swedes in position of power having a positiveattitude to Nuclear power were chosen. Three rhetorical theories (the rhetorical arena, stasis andethos, pathos and logos) were used with the research question in focus.Result & Conclusions: The analyses resulted in conclusions about the strategies used by the participants such as: the importance of contexts, meaning for example that the greenhouse effect legitimizes Nuclear power as a source of energy with important benefits.

Risk eller Resurs: En studie av hur riskbegreppet konstrueras i den svenska kärnkraftsdebatten

Looking at the debate on Nuclear power in Sweden, the issue of risk is central to understanding the difficulties in resolving differences between proponents and opponents. I sought to answer the research question: "how is the concept of risk constructed in the Nuclear power debate in Sweden?" Four main aspects of risk construction were defined and investigated to identify differences between sides in the debate. Through a qualitative study of the debate and its actors I found clear differences in respect to all four aspects of risk construction. First, the perception of Nuclear power as a "normal risk" is common among nuclear opponents in contrast to a largely probabilistic view among proponents.

Centerpartiet och kärnkraften : En studie av förändring i ett parti

ABSTRACTD Level Essay in Political Science, Autumn Semester 2008 by Mattias Andersson. Tutor: Alf Sundin. ?The Swedish Centre Party and Nuclear power. A Study of Change in a Political Party?The aim of this essay is to examine the policy of the Swedish Centre Party on Nuclear power.

Vindkraft eller kärnkraft - En jämförelse

The scope of this project is to make a comparison of costs associated with wind and Nuclear power in order to decide which one of these is the most suitable in the case of an increased demand for electricity. It is also investigated if there are other factors that can influence the choice of energy source.An average cost is calculated in terms of kronor per kilowatt-hour (SEK/kWh) using cost of investment, operation & maintenance and taxes & subsidies. Total investment cost is recalculated to production cost using the annuity method at three different interest rates (6%, 9% and 12%).The comparison is made between three cases of wind power and two cases of Nuclear power. For wind power there are two ocean-based (300MW and 100MW installed capacity, respectively) and one land-based (60MW) wind farm. For Nuclear power there is one EPR-reactor (1600MW) and one AP1000-reactor (1100MW).

Risken för översvämningar vid de svenska kärnkraftverken : en statistisk och historisk extremvärdesanalys

This thesis investigates the overall risks of flooding over the Design Basis Flooding Level (DBFL) at the Swedish Nuclear power plants (Oskarshamn, Ringhals and Forsmark), using statistical data and methods, but also considers historical events which might affect the overall risk of flooding at the specified sites.Considering the nuclear accident which happened in Fukushima in conjuction with the earthquake and tsunami which struck eastern Japan on 11 March 2011, operators and licensors of Nuclear power plants all over the world conducted reviews and investigations on the overall risks posed to the plants from external events. One important such event is extreme water level.One part of the thesis includes an extreme value analysis (using Generalized Extreme Value distribution and Generalized Pareto distribution) of water level data from SMHI (Sweden's Meteorological and Hydrological Institute) measured at stations close to the Swedish Nuclear power plants. The results of the statistical studies indicate that considering the return period used in the thesis (100 000 years), the water levels at the Swedish Nuclear power plants are not expected to exceed DBFL.The other part of the thesis consists of a historical study of extreme weather-related events. The results of this study indicate that no historical events seem to have occured which would indicate a higher risk of flooding than the one suggested by the statistical study. .

Analys av skillnader mellan internationell och svensk rapportering av inträffade händelser på kärnkraftverk

Report of diploma work conducted at the Swedish Radiation Safety Authority (SSM) as part of the bachelors program in Nuclear Engineering at Uppsala University.All Nuclear power plants in Sweden are obliged to report any deficiency in their barriers or the defense in depth in obedience to SSM?s regulations concerning safety in nuclear facilities. In addition, there is an international system for reporting such events. The purpose of this thesis is to study the Swedish report system and to analyze the differences between Swedish and international event reporting.In the Swedish system, SSM?s regulations are effectuated by means of event reports classified as category 1-3, designed individually at each Swedish facility.

Verksamhetsanalys Jämförelse mellan IAEA och OKG AB inom E.ON-koncernen

The safety and safety work on OKG, Oskarshamns Kraftgrupp, is supervised by SKI, Swedish Nuclear power inspectorate. The task of SKI is to inspect that the Nuclear power plants of Sweden runs in a safe way. The proprietor of the permit who runs Nuclear power plants has the responsibility to maintain the required safety to run a plant. SKI publishes a number of statue books that OKG has to meet to be able to run the plants. SKI recommends in SKIFS 2 004:1, that OKG work with the safety requirements of IAEA.

Forsmark 3 ?Ett Framtida Biobränslekraftverk?

Recent turmoil surrounding Nuclear power as an energy source, especially since the accidentat Fukushima, has largely contributed to the debate of whether or not Nuclear power should beused as an energy source. This study has examined the economic feasibility of replacingForsmark?s 3rd nuclear reactor with a bio fueled power plant, and find out how this could bedone.The power generation that has to be replaced is equal to 1170 MWe. To replace this, 6 largescaleCFB-boilers, each providing over 200 MWe, were necessary. In addition to this, eachboiler required their respective turbine sets, comprising one high-pressure-, and one lowpressureturbine with intermediate reheating capacities.Based on this, a rankine-cycle was modeled using the software EES, to be able to calculatethe total heat required in the power plant.

Natursyn och kärnkraft / View of nature and nuclear power

Kärnkraften har så länge den funnits varit en omdebatterad energikälla. Syftet med denna uppsats är att utreda och få en bild av hur och på vilket sätt natursynen hänger ihop med åsikter om kärnkraft. Jag har redogjort för vad energi är, kärnkraftens historia i Sverige och som energikälla samt beskrivit för- och nackdelarna med kärnkraften. För att kunna ge en bild av kärnkraft och natursyn har jag genomfört kvalitativa intervjuer med personer som på olika sätt är insatta i problematiken kring kärnkraften. Min undersökning visar bland annat att natursyn är ett komplext och stort begrepp som vi bör vara medvetna om hur det fungerar i arbetet för att förbättra miljön..

The aim of the study is to investigate if the nuclear family has the status of ideals and norms in the family law secretaries practice. In order to achieve the aim of conducted four interviews with family law secretaries in Stockholm city. The interviews have been the main data collection. Theoretical concepts which are central in the study are: the nuclear family, institution, ideals, standards, and established and outsiders.

Fred ? till vilket pris? ? En studie om etiken kring kärnvapeninnehav

This bachelor thesis focuses on the ethics concerning the possession of nuclear weapons seen from a deontological and utilitarian perspective. I have also considered the aspects of International law, the Just-war Theory, and Michael Walzer's Legalist Paradigm. The research question that guides my essay is: Is it possible to ethically justify a country's possession of nuclear arms, which results in direct and indirect threats against other countries?I have chosen to focus my essay on the period of 1945 to 1990, also referred to as the Cold War. I find the bipolar system that existed between the USA and the Soviet Union as a good empirical example, during which the nuclear arms debate constantly took place.The result that my thesis brings is rather ambiguous.

Aspirantutbildningsprogram

Because of the currently large recruitment needs within the Swedish Nuclear powerindustry, it is necessary to recruit trainers from other recruitment groups than that ofexperienced operators at Nuclear power plants. The foundation for a trainingprogram regarding these recruitment groups, here called ?aspirants?, has in this thesisbeen prepared. It contains a suggestion for main topics in the program. It also includesdiscussion on the balance between forms of education and a concrete example ofhow a lesson could be performed.These suggestions has been developed through analysis of interviews and surveyresponses from student groups most suited for the propositioned trainee program,and individuals with service as a trainer or closely linked to training activities withinthe industry.The analysis suggests that the candidates gets, besides the opportunity to practice asoperating staff before the theoretical training begins, a training program, tightly boundto the power plant with multiple instances of practice and the chance of going intothe power plant and see how things that are being raised in theory, look in real life.The practice, in addition to helping to create an understanding of the plant, it will facilitate networking with the operations staff to build a relationship and trust.Candidates should have plenty of opportunity to educate and see both other aspirantsand experienced trainers train.
