Characteristics of fan cooling towers
Joska, Jakub ; Milčák, Pavel (referee) ; Pospíšil, Jiří (advisor)
This diploma thesis deals with the problematics of fan cooling towers. The very first part of the text is research, focusing mainly on the theory of cooling and the function of fan cooling towers in general. The following chapter deals with the water resource management of the Dukovany nuclear power plant and the specification of its objects of forced draft cooling towers. The second part describes a computational model created to determine the cooling performance of these towers under the given input conditions. In the following chapters, the results from the computational model are compared with the available data from warranty measurements and with the provided characteristics. The final pages deal with the study of the influence of changes in input parameters on the cooling performance and the research of the behavior of the cooling towers under extreme weather conditions.

Design of the tertiary circuit for a nuclear power plant
Flajsarová, Alexandra ; Baláš, Marek (referee) ; Milčák, Pavel (advisor)
At the beginning of the bachelor´s thesis, a basic description of nuclear power plants is presented. The main attention is paid to nuclear power plants with light-water pressurized reactors. This type of nuclear reactor is the most common one in the world, and i tis also used in both Czech nuclear power plants. A significant part of the thesis deals with the tertiary circuit of a nuclear power plant. Therefore, cooling methods, cooling towers, and condensers are described in the thesis. The main goal of the thesis was to calculate the amount of make-up water in the tertiary circuit of a nuclear power plant with a reactor with nominal output of 1200 MWe and to determine whether a nuclear power plant with these parameters would be capable of operation in the conditions specific for the Dukovany Nuclear Power Plant with the use of make-up water from the Jihlava River.

Reinforced concrete structure of the cooling tower
Vostal, Lukáš ; Švaříčková, Ivana (referee) ; Šulák, Pavel (advisor)
The content of the bachelor thesis is structural analysis of cooling tower fundamental construction. Modeling of the computational model and the calculation of internal forces of cooling tower fundamental construction in Scia Engineer. The reinforced concrete parts of the structure are assessed at the ultimate limit state and the subsoil is assessed at serviceability limit state. Part of the thesis is also the desing of the reinforcement of the foundation structure and processing of the drawings.

Determination of the performance of the cooling circuit - cooling tower
Velešík, Aleš ; Hanzal, Luděk (referee) ; Baláš, Marek (advisor)
The aim of this work is to determine the performance and description of the cooling circle in the cooling tower. In order to do that there was applied the linear regression approach in order to create structural empirical model of the cooling tower. The data obtained was analysed through QC expert software, which, if correct data applied, identifies suitable model for specific tower. The models created will be used for diagnostics of the cooling circles and as a comparison tool with other cooling towers in the future. Thus, the findings of this thesis are polynoms, which in thic technological setup characterise the models of the cooling towers.

Solution technology of cooling tower component
Dobiáš, Radek ; Kubík, Roman (referee) ; Kalivoda, Milan (advisor)
The content of this diploma thesis is solution of production technology of cooling tower component. A model the cooling tower according to customer specifications is designed. There are selected 2 plates from steel construction that will be machined by plasma cutting. The technology of production of the plates is also proposed. Technical and economic evaluation of production compares 2 versions of plate production using unconventional metal cutting methods.

Reinforced concrete construction of cooling tower
Zralý, Tomáš ; Buřič, Pavel (referee) ; Šulák, Pavel (advisor)
There was solved reinforced concrete cooling tower in the diploma thesis. This is a rotationally symmetrical construction. The cooling tower is concrete shell on columns. The cooling tower was solved using the finite element method, computer program Midas FEA. The work includes: calculation using the program Midas FEA, comparison of load between eurocode and foreign literature, the design of shell and columns, drawings form

The impact of Nuclear Power Plant Temelin on the climate of surrounding area
BARÁTOVÁ, Michaela
BARÁTOVÁ, M. (2012): The impact of Nuclear Power Plant Temelin on the climate of surrounding area. Bachelor Thesis. University of South Bohemia, Pedagogical faculty, Department of Geography. 128 pages Nuclear power plant Temelin is a dominant, which forms silhouette of the Ceskobudejovicka basin. It is a construction, which faces and resists criticism from environmental organizations. Benefit or threat to South Bohemia? Undoubtebly, the area of disputes between politicians of Czech Republic and Austria. This bachelor thesis evaluates especially climate impacts of Nuclear Power Plant Temelin. Theoretical - methodological base is mainly focused on the discussion of literature, in general and in specific terms researched the topic and related hypotheses. General section then describes the basic physical - geographical characteristics of the selected area, special emphasis is placed on climatography. An integral part of the general section is a brief description of working the youngest European power plant. The analytical section is dedicated to monitoring climate of surrounding area ETE using data that was recorded by Observatory Czech Hydrometeorological Office in Temelin and the results are compared with data that were recorded during the same period by in České Budějovice. The monitoring of climate surrounding area of Nuclear Power Plant is assessed from two perspectives. The first view sees the climate before the start of nuclear power plants in operation, so from 1989 to 2001; the second look is focused on changes which was formed after the running of nuclear power plants in 2002. The analytical part shows the possible changes in selected climatic characteristics that could be caused by cooling tower plume.
