Influence of electricity generation on the environment
Žák, Jiří ; Novotný, Jan (referee) ; Matoušek, Antonín (advisor)
The concern of this Bachelor Thesis is current structure of electric energy sources in Czech Republic and their influence on the environment. The theoretical part maps the current state of energetics, structure of sources, consumption and installable output in ES CR. In the thesis, there is shown evolution of balance of electricity since 1988 and netto production of electricity in CR. There is also decribed export and import of electricity in the year 2008 and determination of the influence of different energetic equipments on the environment. The practical part deals with the emission of individual types of power stations, their manufacturing, calculation and possibilities of decreasing amount of carbon dioxide emission from the electric energy manufactories. Next point considers predicted development of equipments in relation to the environment. In the end, there is the overall evaluation of achieved information and results with influence on the environment.

Nuclear energetics in CR and in the world
Peroutka, Tomáš ; Bartošík, Tomáš (referee) ; Mastný, Petr (advisor)
This work is about a basic principles of nuclear reaction, creation of nuclear reaction and its development. Here is also described contemporary status and its level of progression. The first part is about a history of nuclear energy – its beginnings and further progress. Next the work deals with a nuclear power stations, nuclear reactors etc. The other part of this work is based on a nuclear waste. Then, I will write about a future of nuclear energy. The last point is creating the enegetic conception of our country.

Treatment of nuclear waste in nuclear power plants and hospital facilities
Vitovská, Michaela ; Kermes, Vít (referee) ; Tabasová, Andrea (advisor)
The bachelor’s thesis at hand is aimed at issues related to formation, storage and processing of radioactive waste – the issues that are widely discussed and dealt with in media. The thesis is concerned not only with formation of radioactive waste in the Dukovany Nuclear Power Station, but also with emerging radioactive institutional waste that originates in hospitals predominantly during treatment of cancer. The thesis provides classification of wastes and description of how these wastes are handled in individual facilities. The thesis is based on findings and technical materials obtained during visits to specialized workplaces at the Dukovany Nuclear Power Station and the University Hospital Brno, the Department of Nuclear Medicine.

Ecological problems energetics CR
Šilar, Martin ; Bok, Jaromír (referee) ; Matoušek, Antonín (advisor)
This project presents the current status of power resources and supply in the Czech Republic and examines its different connections with ecology. The existing situation in energetics is described in the first chapter of the thesis. This chapter contains general information as well as an analysis of the progress to date related to the structure of installed power and to the amount of electricity generation and their consumption. The description of the common influence of energetics on the environment is provided in the following chapter, which also introduces the next step, namely a short survey of the characteristics of the currently used energy resources and their direct relationship to the monitored ecological problems. The practical part of the project is based on the calculation of emission in the fifteen biggest thermal power station in the Czech Republic. The calculated amounts of emission are compared with the related features of nuclear waste. The last chapter contains information about the EU legislation concerning the reduction of carbon dioxide. In this respect, there are presented also the measures planned to facilitate the reduction of carbon dioxide in Czech Republic.

Effect of a nuclear power plant in terms of radiatin burden
Vániš, Jiří ; Procházka, Zdeněk (referee) ; Belatka, Martin (advisor)
This text deals with ionizing radiation affecting nuclear power plant personnel and surrounding population. Irradiation limits of radiological industry personnel are also mentioned along with ways of protecting them and checks on absorbed ionizing radiation dose. In conclusion, a nuclear power plant, as a source of ionizing radiation, and its effects on contamination of water sources and gas vents are evaluated. The next part be engaged problematical of storage nuclear waste from the time, when is removed the nuclear waste from nuclear reactor, trough permanent storage.

Ecological problems energetics CR
Mahdal, Vlastimil ; Ptáček, Michal (referee) ; Matoušek, Antonín (advisor)
This project presents the current state of power engineering, power resources in the Czech Republic and the impact of power resources on the environment. The first chapter describes the nature of the power engineering of the Czech Republic and the structure of primary energy sources, the next chapter present the current state of electricity, there is also described the structure of instaled capacity, consumption and production of electrical energy. The following section describes the impact of the power stations on the environment and their current status in the Czech Republic. The practical part provides information of calculating emissions using emission factors for power stations of company ČEZ, a.s. and about the storage of nuclear waste. The last chapter is dedicated to reducing carbon dioxide emissions in the European Union and describes measures in the Czech Republic for reducing these emissions.

Nuclear fission reactions
Michal, Jakub ; Lachman, Jakub (referee) ; Sitek, Tomáš (advisor)
Understanding of physical principles of nuclear fission and nuclear reactions is crucial for operation of a nuclear power plant. Both, light nuclides, and heavy nuclides, are fissionable, but retrieve enough energy is possible only for the heavy ones such as uranium and plutonium. There are many possible ways how the nuclear fission of the same nuclide can take place, however the energetic balance remains almost the same. Another important factor is the yield of the different isotopes. After fission they are usually in an excited state and decay by one of the decay modes. The nuclear fuels are normally based on the fissile nuclides mainly of the uranium and minorly on the plutonium. Despite the plutonium is originally in the fuel, it is one of the main sources of the released energy from nuclear fission. Problems of nuclear fission are then connected with the nuclear waste and possible proliferation of nuclear weapons.

Ethical issues concerning the disposal of spent nuclear waste in the Czech republic
HORNÁ, Vladana
My work deals with ethical problems of depositing nuclear waste in the Czech Republic. It points to a divide in our society concerning utilization of energy through atomic fission. Ambivalence towards the issue relates to problems connected with the final deposit of nuclear waste into a nuclear waste repository. Electric energy affects the life of every citizen therefore my work shows the necessity to include such a topic into teaching.
