Bibliography: pages 168-174. / The Emergency Electric Power Supply Systems at Pressurized Water Reactor Nuclear Power Plants are reviewed, problem areas are identified, and recommendations are made for existing and future Nuclear Power Plants. A simplified introduction to a typical Pressurized Water Nuclear Reactor is given and the problems associated with the commercial use of nuclear power are discussed. An overview of the Nuclear industry's solutions is presented and covers the Reliability of equipment and the American Regulatory requirements. The alternating and direct current power supply systems are examined in terms of plant operational state and equipment type (Diesel generators, Grid network, Lead-acid batteries, Battery chargers, Inverters, and Power Distribution networks). The trends in the design of Emergency Electric Power supply systems at Nuclear Power Plants are presented. The loss of all alternating current power, known as Station Blackout, is discussed and the American and European response to this. problem is presented. Problems experienced in the direct current systems are discussed and solutions are presented. The experience at Koeberg Nuclear Power station with Lead-acid batteries is included in the discussion. The thesis concludes with recommendations for designers and operators of the Electric Power Supply Systems at Nuclear Power Stations.

The purpose of this essay is to perform an empirical test of the hypothesis that distance to an operative nuclear power plant will affect property pricing. The focus is on three counties in Sweden that have nuclear power plants. The hedonic pricing method is employed to fulfill the purpose. This involves an econometric cross-section analysis where the price of a property is assumed to be influenced by various housing characteristics, a distance variable, and time specific effects. The data were provided by Svensk Mäklarstatistik and were collected from the period 2005-2021. The material included information regarding property prices and property characteristics. The results suggest that there is a positive statistical relationship between the level of property prices and the distance to an operative nuclear power plant. However, we only find this relationship for Varberg and Oskarshamn. This result is in some contrast to the findings of a few previous studies. / Syftet med denna uppsats är att genomföra ett empiriskt test av hypotesen att avståndet till ett operativt kärnkraftverk påverkar nivån på fastighetspriserna i de tre kommuner i Sverige som har etablerade kärnkraftverk. Detta syfte besvaras genom att tillämpa den så kallade fastighetsvärdemetoden. En ekonometrisk modell specificeras där den beroende variabeln, priset på en fastighet, förklaras av olika karakteristik hos fastigheten samt bostaden, avståndet till närmaste operativa kärnkraftverk, och tidsspecifika effekter. Datamaterialet samlades in från Svensk Mäklarstatistik och innehöll data från tidsperioden 2005 till 2021. Datamaterialet bestod av fastighetspriser samt fastigheternas karaktärsdrag. Resultaten visar att det finns ett positivt statistiskt samband mellan nivån på fastighetspriserna och avståndet till ett operativt kärnkraftverk. Fastighetspriserna tenderar, allt annat lika, att vara lägre på platser som ligger nära kärnkraftverket men detta resultat erhålls endast för Varberg och Oskarshamn. Uppsatsens resultat skiljer sig åt från ett flertal tidigare studier.

Kärnkraften har så länge den funnits varit en omdebatterad energikälla. Syftet med dennauppsats är att utreda och få en bild av hur och på vilket sätt natursynen hänger ihop medåsikter om kärnkraft. Jag har redogjort för vad energi är, kärnkraftens historia i Sverige ochsom energikälla samt beskrivit för- och nackdelarna med kärnkraften. För att kunna ge en bildav kärnkraft och natursyn har jag genomfört kvalitativa intervjuer med personer som på olikasätt är insatta i problematiken kring kärnkraften. Min undersökning visar bland annat attnatursyn är ett komplext och stort begrepp som vi bör vara medvetna om hur det fungerar iarbetet för att förbättra miljön. / The nuclear power have, as long as it has been existing, been a discussed source of energy.The purpose with this report is to study and to get a picture if how and in what way the viewof nature cohere with the opinions about nuclear power. I have described what energy is, thehistory of nuclear power in Sweden and as a source of energy. I have also described thepositive and the negative aspects of nuclear power. To be able to present a picture of view ofnature and nuclear power I have done quality interviews with persons who, in different ways,are familiar with the problems of nuclear power. My investigation has shown that view ofnature is a complex and wide concept that we should be aware of in our work towards a moresustainable society.

The long-term operational safety of nuclear power plants is of utmost importance. Seismic isolation has been shown to be effective in reducing the demands on structures in many applications, including nuclear power plants (NPP). Many designs for Generation III+ NPP include a large passive cooling tank as a measure of safety that can be used during power failure. In a large seismic event, the fluid in the tank may be excited, and while the phenomenon of fluid-structure interaction (FSI) has also been studied in the context of base isolated liquid storage tanks, the effect on seismically isolated NPP has not yet been explored. This thesis presents a two-part study on a base isolated NPP with friction pendulum bearings. The first part of the study compares the usage of a linear fluid model to a nonlinear fluid model in determining tank and structural demand parameters. The linear fluid model was found to represent the nonlinear fluid model well for preliminary analysis apart from peak sloshing height, which it consistently underestimated. The second part of the study uses a linear fluid model, an empty tank model and a rigid fluid model to investigate the influence of FSI on the structural response of an isolated NPP compared to a fixed base NPP. In general, the response of a fixed base NPP considering FSI using a linear fluid model can typically be bound by the results assuming an empty tank and assuming a full tank with rigid fluid mass. However, this does not hold for the base isolated NPP, as the peak isolation displacement for an NPP with a linear fluid model at design depth is greater than the peak isolation displacement than the same NPP with an empty tank and with a rigid fluid model. / Thesis / Master of Applied Science (MASc)
