Czech Public Opinion on Nuclear Energy – May 2018
Červenka, Jan ; Ďurďovič, Martin
In its May 2018 survey, the Our Society series included a battery of questions on issues of nuclear energy. The survey examined public opinion about whether the proportion of nuclear energy in electricity production should increase or decrease in future, what people think about completing the third and fourth units of the Temelín Nuclear Power Station (TNPS), whether or not they are concerned about the use of nuclear energy in the country, and whether they have confidence in the government’s decisions about the development of nuclear energy.

Recent morphogenetic processes in locality of the Temelín nuclear power station
Janouchová, Vladěna ; Kalvoda, Jan (advisor) ; Vilímek, Vít (referee)
This presented thesis deals with recent morphogenetic processes in the area of nuclear power station Temelín (JETE). The study is primarily focused on the characteristics of the natural environment, geomorphological evolution of the area in the younger Cenozoic and the evolution of the surface shapes in the Quaternary. The thesis also contains the characteristics of types of recent geomorphological processes in the area of nuclear power station Temelín and an evaluation of recent geomorphological processes in relation to the natural hazards to JETE. The main objective of this thesis is a description of geomorphological processes in the area of nuclear power station Temelín through the literature search and connecting of geomorphological processes with natural hazards in the studied area. Keywords: morphogenetic processes, Temelin, nuclear power station

Austrian Green Party and its role in Austrian fight against Nuclear Power Plant Temelín
Černá, Petra ; Šafařík, Petr (advisor) ; Nigrin, Tomáš (referee)
Bachelor thesis Austrian Green Party and its role in Austrian fight against Nuclear Power Plant Temelín concerns relationship between Austrian Federation and the Czech Republic within the field of the nuclear industry; namely it concerns the situation around the building and lately planned completion of constructing of the Czech nuclear power plant Temelín. Primarily, the thesis tries to analyse an Austrian green party Die Grünen - Die grüne Alternative attitude and its communication of the Temelín problematic in years 2004-2013, when both countries have been member countries of the European Union. At first, thesis introduces the issue and main participants. At the very beginning it describes Temelín building itself, including the fear connected with its building and lately with its existence and completion. After that it summarizes the development of Austrian Greens and it analyses their party materials in which we can find anti-nuclear topics. Then it describes attitude of the main Austrian political parties to a nuclear theme. In the crucial part it also analyses, except the communication of Die Grünen on federal and supranational level, the behaviour of the local Green Party offices in individual Austrian lands and evaluated their orientation towards Temelín. It uses the materials which are...

Nuclear power plants
Musil, Jiří ; Šnajdárek, Ladislav (referee) ; Pospíšil, Jiří (advisor)
This bachelor's thesis deals with history and future of nuclear reactors, it describes nuclear power plants in the Czech Republic and provides a list of promising possibilities of using nuclear energy, that are currently in research. Description of the secondary circuit based on Czech nuclear power plants is also included in this thesis. In the beginning, some elementary knowledge about nuclear energetics is gathered, to provide readers with basics of this topic.

Nuclear Fuel Margins Increasing at Nuclear Power Plant Dukovany
Vrábel, Radek ; ČEZ,, Ondřej Zlámal, (referee) ; Katovský, Karel (advisor)
This bachelor‘s thesis deals with power uprates and the extension of the nuclear fuel cycle at Czech nuclear power plants. The beginning of this thesis aims at improving the reader’s knowledge about nuclear reactors and nuclear fuel cycle. A whole chapter is dedicated to the development of nuclear fuel cycle at the nuclear power plant Dukovany. The progress in the field of nuclear fuels complements the development of the nuclear fuel cycle, thus providing visible benefits.

Nuclear Fuel for Pressurized Water Reactors
Smetana, Jan ; Vojáčková, Jitka (referee) ; Katovský, Karel (advisor)
This bachelor thesis deals with structural characteristics of nuclear fuels, where most of the attention is paid to pressurized water reactors. The examples of the nuclear fuels implementation for each reactor type are mentioned for reader's better understanding. A brief history of pressurized water reactors is also listed, VVER reactors particularly. The nuclear fuel development for pressurized water reactors is demonstrated on the example of the development of fuel for our nuclear power plants Dukovany and Temelin, changes of fuel structure are emphasized. In the thesis there is also carried out a computational comparison of several selected parameters of used nuclear fuel during the operation of the nuclear power plant Dukovany.

Nuclear Fuel Cycle of Temelin NPP
Ježek, Martin ; Zlámal, Ondřej (referee) ; Katovský, Karel (advisor)
This bachelor's thesis deals with the central part of a fuel cycle in the power plant of Temelín. It describes generally the whole fuel cycle, from the process of uranium mining up to permanent storage of burned-up material and it shortly mentiones possibilities of its remaking. Neverthless, the main point is the middle part of the fuel cycle. In the next parts, the thesis concentrates on the power plant of Temelín. It describes shortly the WER-1000 reactor, which is being used there, and the active zone as well. There is a further description of both fuels used there, a fuel form a Russian corporation of TVEL, which is used nowadays, as well as a fuel from an American corporation of Westinghouse used in the past. The thesis then deals with the development of a fuel cycle from the moment of launching the power plant up to the present. The problems with the fuel from the American corporation are mentioned here as well. Then it concentrates on more-than-year long cycles and tries to quantify their contribution. The thesis contains a very simple project of an elongated fuel cycle and his evaluation from the point of working economy and organisation of shutdowns.

Analysis of the Most Common Causes of Nuclear Fuel Failures During Operation
Ježek, Martin ; ČEZ,, Ondřej Zlámal, (referee) ; Katovský, Karel (advisor)
Nuclear fuel failures during the reactor operation happen quite often in the world. The theoretical part of this thesis is dedicated to the most common causes of nuclear fuel failures. It describes failure mechanism and corrective actions. The unfavorable trends in nuclear fuel behavior are prevented by suitable method of nuclear fuel monitoring. Some of them may affect the safety of the power plant. For example, the fuel assembly bow affects the function of rod cluster control assembly. Another part, which describes inspection methods, is devoted to inspection and repair of nuclear fuel. The thesis concentrates on the Temelin NPP, where there was implemented post-irradiation inspection program for checking compatibility between Westinghouse's fuel assemblies and water chemistry of reactor VVER. This program continues even after the change of nuclear fuel supplier. Practical part of this thesis is dedicated to proposal of a new method of fuel assembly bow measurement for Temelin NPP based on ultrasound. This proposal is supported by measurement on the experimental device for detection of spacer grid position developed by Research Centre Rez.

The activities of the Czech ecological organisations: Case study Temelin
Novotná, Marcela ; Vymětal, Petr (advisor) ; Lisa, Aleš (referee)
This diploma thesis deals with activities of the Czech ecological organisations which were active in case of nuclear power plant Temelin after its breaking-in. The thesis is divided into four chapters. The first one focuses on the definition of the ecological organisation (movement). In the second chapter, the attention is paid to the history of foundation and functioning of the nuclear power plant Temelin. The third chapter is about advantages and disadvantages of the nuclear power. The last chapter focuses on the analysis of activities of the Czech ecological organisations which opposed or supported the nuclear power plant Temelin.
