The design of nuclear power plant steam generator
Zimmermann, Jakub ; Baláš, Marek (referee) ; Milčák, Pavel (advisor)
The bachelor's thesis consists of three parts. The introductory research section briefly describes the history of nuclear energy, followed by an analysis of the three circuits (primary, secondary, and tertiary) in a nuclear power plant. The second part provides a detailed description of various steam generators used worldwide. The third and main part of this bachelor's thesis covers the thermal calculation of a steam generator, focusing on determining the heat exchange surface area and the length of heat exchange tubes inside, followed by a comparison of steam generator sizes based on their number of connections to a single nuclear reactor block. At the end, I modelled a model and created a diagram of the steam generator based on the results from the thermal calculation.

The impact of the nuclear accident at Chernobyl on the environment
Dvořáková, Markéta ; Přibil, Rudolf (advisor) ; Braniš, Martin (referee)
Modern civilization is dependent on the production of energy. But there are only two energy sources that can cover our energy needs: the energy produced by burning fossil fuels and the energy produced by nuclear fission. People are afraid of nuclear accidents and storage of radioactive waste in relation with the use of nuclear energy. My work focuses on the risk of a nuclear accident, which is demonstrated on the Chernobyl nuclear accident. There were obsolete types of nuclear reactors at Chernobyl. The staff, which serviced the power plant, was inadequately prepared for the experiment. A lot of radionuclides released into atmosphere after the explosion at Chernobyl. They affected mainly the near area from the power plant. There was announced the thirty kilometers large Zone of Alienation. My work deals with the consequences of the accident at Chernobyl for environment - health effects for people and the exposure to animals and plants in the near but also in farther area from the Chernobyl nuclear power plant.

Environmental Impact Assessment in the European, Austrian and Czech Legal Regulation
Škrabalová, Kristina ; Damohorský, Milan (advisor) ; Stejskal, Vojtěch (referee)
The process of environmental impact assessment is a control procedure that aims to summarize and evaluate the impact of a project on the environment at the stage of project planning and thus to reduce its potential negative impacts in the future. One of the main ideas of the EIA process is to avoid since the very beginning problems and confrontation which would otherwise appear in the future in connection with the planned project. This principle is particularly important in cases of transboundary assessment where communication between countries and joint consultations on the project in its early stages of planning might prevent potential conflicts and disruption of mutual relations in the future resulting from an already implemented plan. The cornerstone of a transboundary assessment is the understanding that the harmful effects of a specific project do not stop at the borders of one state, but can reach a territory of many other countries, mutual cooperation in this subject is thus with regard to environmental protection necessary. The necessity of such a cooperation on one hand, as well as its pitfalls and difficulties on the other hand, are illustrated in the case of transboundary EIA between the Czech Republic and Austria, that is specifically in the case of the construction of the nuclear power plant...

Central Europe after Fukushima:the media image of nuclear energetics in the Czech republic,Germany,Austria and Slovakia after Fukušima disaster
Aliapuliu, Lenka ; Křeček, Jan (advisor) ; Krobová, Tereza (referee)
The thesis deals with the image of nuclear energetics in four selected daily newspapers after Fukushima nuclear power plant accident in March 2011. The goal of the thesis is to compare how the public was informed about a nuclear disaster in Fukushima by leading daily newspapers in four selected countries, with focus on their attitude to this disaster, and how, if at all, this event influenced the direction of the countries in terms of energy resources. The Czech Republic, Germany, Austria and Slovakia were selected as representative countries. Each of these countries is represented by a daily newspaper, such as Mladá fronta Dnes, Süddeutsche Zeitung, Der Standard and SME. The theoretical part of the thesis provides the explanation of basic concepts of media communication and news characteristics. The attention is also given to the issue of nuclear energetics. In the empirical part, the image of nuclear power plants in selected countries immediately after the Japanese disaster is captured. Powered by TCPDF (www.tcpdf.org)

Proposal of Communication Strategy
Konečný, David ; Jirušek,, Martin (referee) ; Chlebovský, Vít (advisor)
This diploma thesis deals with the elaboration of proposals or improvements in marketing communication of the Dukovany nuclear power plant. The thesis is divided into three main parts. The first part includes necessary theoretical resources for building a communication strategy. The second part comprises of various analyses, which are necessary to obtain information for the concluding part of the thesis. The proposal of the communication strategy itself is based on conclusions of the analyses focused on communication of the operator of the Dukovany NPP and on the selected communication tools currently used by this power plant. It is also based on the data acquired from the quantitative survey conducted with the purpose of finding out the actual public perception of the Dukovany NPP amongst young people and their attitude towards nuclear energy in general.

Securitising Nuclear Energy: Analysis of speech acts related to the possible construction of a new reactor at the existing Dukovany Nuclear Power Station
Dytrych, Simon ; Holubcová, Jitka (advisor) ; Kučera, Tomáš (referee)
This Master's thesis dealt with securitization attempts related to the planned construction of a new reactor at the Dukovany NPP. Therefore, its aim was to find, analyse and explain securitization speech acts associated with the planned reactor, in the period from summer 2015 to December 2020 using the critical discourse analysis approach. The results show that securitization speech acts of this kind do appear in the Czech public sphere and are articulated mainly by four groups of actors: representatives of Austria, Czech environmental NGOs, Czech governmental representatives, and Czech political opposition. These actors have different goals: to stop the construction of the reactor, to implement the construction of the reactor, or to influence the way in which the construction will be implemented. One case of successful securitization was found in the outcome: The Czech government was able to enforce extraordinary measures that deviated from standard democratic processes using security-based arguments. Their goal was to implement the construction of the reactor. It remains to add that the research also revealed three important functional actors who co-created the discourse: the BIS secret service, the SÚJB nuclear safety office and the company ČEZ.

Regional impact on unemployment at the hypothetical closure of Temelín and Dukovany nuclear power plants
Hájková, Eva ; Říhová, Gabriela (advisor) ; Jílek, Petr (referee)
This Behelor´s thesis deals with closure of nuclear power plants Temelín and Dukovany. The most important topic is regional unemployment cause this closure. Main goal this thesis is to find out whether closure will only influence the regions in which the power plants operate or other regions. The theoretical part contains basic concepts related to topics such as unemployment, migration or energy. The practical part analyzes data from the Czech Statistical Office related to commuting and interviews with the representatives of each of the power plants. Based on this analysis, it can be said that the closure would affect most of the regions in which the power plants are located. In the case of power plant Dukovany closure affect region from another region. In the case of power plant Temelín closure affect only region in which operate.
