Submitted in partial fulfilment of the requirements for the degree of Master of Technology (M Tech) Cape Peninsula University of Technology 2014 / The increased demand for electricity has persuaded a number of countries world-wide to re-evaluate their strategies on energy production. These strategies largely focus on expanding the power generation capacity and adjustment of the amount of energy generated from various sources, in the light of global climate change, security of energy supply and fossil fuel price volatility (OECD report, 2010). In the United States of America (USA), for example, according to Ansolabehere & Konisky (2009), a projection of 40% rise in electricity demand is forecast over the next three decades presenting a need for diversifying the energy mix and expanding power generation capacity. The need for expanding energy supply is increasingly becoming more pronounced in a number of developing countries as well. The demand for energy warrants generation of energy from a variety of sources: coal-fired power plants, gas turbines, wind farms and nuclear power facilities. In order to transmit electricity efficiently these facilities need to be located near residential centres. The challenges associated with the construction of such centres are multi-fold. The option of nuclear power generation is a very divisive issue with as many opponents as supporters, and it has certainly been put back on the agenda in many countries including China, India and Russia, with over 250 nuclear projects in the pipeline globally. The construction of nuclear power plants is often masked with opposition from the public resulting in huge delays in completing the projects yet, nuclear energy is considered as one of the most comprehensive and cost-effective generating options which has the potential to reduce carbon dioxide emissions, meet the ever-increasing demand for electricity as well as making a crucial contribution to energy independence and security of supply.

[pt] A presente pesquisa de mestrado contribui para a melhoria da confiabilidade metrológica de componentes usinados, utilizados na indústria nuclear para produção de energia elétrica, produzidos com reduzidas tolerâncias definidas em projeto. O trabalho é de interesse da empresa Indústrias Nucleares do Brasil (INB), que atua na cadeia produtiva do urânio e produz o elemento combustível para as usinas nucleares de Angra, pois aprimora a analise do processo de medir. Cumprindo o objetivo da dissertação e fazendo uso da técnica de medição por coordenadas, foi desenvolvida uma metodologia para avaliação do processo de inspeção dimensional de componentes usinados da indústria nuclear. A motivação é a melhoria da confiabilidade metrológica requerida na inspeção, agregando conhecimento e inovação tecnológica. O trabalho incorpora uma análise das incertezas associadas ao processo de medição por coordenadas de componentes usinados. A metodologia utiliza a pesquisa bibliográfica e a experimental e, à luz dos métodos de avaliação de incertezas baseados numa formulação estatística, avalia processos de medição de interesse da indústria nuclear. Dentre os resultados são caracterizadas as influências na medição da característica objeto da medição; é avaliada a divergência da medição em relação a um padrão e desenvolvida uma ferramenta para a avaliação e melhoria do processo de medição. Como conclusão, o trabalho contribui com o aprimoramento da técnica de medição por coordenadas incorporando inovações tecnológicas na melhoria da qualidade dos processos de inspeção dimensional. / [en] This Master’s Thesis contributes to the improvement of metrological reliability of machined components that are used in the nuclear industry for the production of electrical energy and which are produced with reduced tolerances defined in the project. The work is of interest to the company Indústrias Nucleares do Brasil (INB), which operates in production of the uranium fuel assemblies for nuclear power plants in Angra, improving the analysis of the measuring process. The dissertation fulfill the goal, by the development of a methodology to use in evaluation of coordinate measuring technique that is used in the process of dimensional inspection of machined components for the nuclear industry. The motivation is to improve the metrological reliability required in the inspection, adding knowledge and technological innovation. The work incorporates an analysis of uncertainties associated with the measurement process by coordinates, of machined components. The methodology uses bibliographic research and experimental methods of evaluation of uncertainty based on a statistical formulation, in measurement procedures of interest to the nuclear industry. In the results are characterized the influences of the measurement on the object characteristic of measurement, the divergence is evaluated by measuring against a standard. It was developed a tool to evaluate and improve the measurement process. In conclusion, the study contributes to the improvement of the coordinate measuring technique incorporating technological innovations, improving the quality of procedures for dimensional inspection.

This thesis aims on solving consequences of nuclear accidents in nucler power plants through commercial insurance. First part of this work introduces internationl liability framework for nuclear accidents, which contains international nuclear threaties and work of International Atomic Energy Agency, altogether with work of czech Agency for nuclear security. Next chapters describe nuclear insurance pools, with special focus on american pool American Nuclear Insurers and Czech nuclear insurance pool. Final part of this thesis goes through two big nuclear accidents in Three Mile Island power plant and in Fukushima power plant. Both accidents are described in wide perspective, including solving and financing of consequences from nuclear insurance and from other financial sources available at the time of disaster.
