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.

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.

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

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.

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.

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.

Nuclear power plant cooling system analysis
Kopřiva, David ; Baláš, Marek (referee) ; Milčák, Pavel (advisor)
This diploma thesis deals with the issue of cooling of nuclear power plants. It briefly covers the currently operating reactor types and the currently used cooling methods of nuclear power plants. The thesis is mainly focused on the use of dry cooling, so the possibilities of dry cooling and their current use in the world are mentioned. The second part of the thesis is focused on the calculation of indirect dry cooling system. The air flowing through the dry coolers cools them. The air flow is caused by the natural draft of the cooling tower in which the dry coolers are located. The calculation of the tower natural draft and the flow losses are part of this work.
