Abstract
The technological progress, the economical growth and the increased life standards inside the European Union, has led in increased energy needs, with direct environmental impact, especially on greenhouse gases level, but also in earth and water pollution due to activities related to generating power. On the introductory chapter of this M.Sc. thesis, we present how a nuclear power plant is operating, as well as the chronicles of nuclear power in today’s EU-27. Then, a reference is made about the factors that make a nuclear power plant functional, such as mineral fuel and the water used for cooling, and in what degree do they affect the land and sea biodiversity respectively. In the main part, we analyze the relationship between nuclear energy, and carbon dioxide emissions and intensity of the 14 EU member states that are operating at least one nuclear power plant in the last decades. Subsequently, the thesis deepens into the high level radioactive waste management problem, analyzing the ways those are stored and suggesting new locations for safe future deposition. Finally, we focus on the future of nuclear energy in the EU, which in conclusion is one of the most sustainable clean energy sources. We present some new advanced nuclear reactors and suggestions are made about policy and institutional framework revisions, in order for nuclear power to be accepted commonly by the European Community as a whole, in order to face up efficiently the ever growing climate crisis.
