Analysis of the condition of the K 220-44 steam turbine drainage pipeline and proposal of corrective measures
Horký, Jiljí ; Milčák, Pavel (referee) ; Šnajdárek, Ladislav (advisor)
This diploma thesis deals with the analysis of the drainage pipeline of the Škoda K 220-44 steam turbine. This turbine is operated in Dukovany Nuclear Power Plant. One part of this work is proposal of corrective measures. The aims of this work include the creation of a search for drainage, steam, erosion corrosion and mapping of defects in long-term operated drainage system. Work also includes the evaluation of measured values of the pipe wall thickness measured by ultrasonic analyzer. In addition, the work contains images created from 3D model, on which the location of defects and measurements are displayed.

The Intermediate Heat Exchanger for ESFR reactor primary circuit
Švihel, Miroslav ; Baláš, Marek (referee) ; Šen, Hugo (advisor)
The thesis is mainly focused on the design of the intermediate heat exchanger primary circuit of the reactor ESFR. Heat exchanger is calculated heat, hydraulic and strength and is finally processed part drawings. There are designed the basic dimensions of the tube bundle and container heat exchanger. There are included an overview of concepts and so far used types IHX at the nuclear power plants with fast reactors. There are also mentioned basic parameters of the project ESFR and evaluated the safety and operational reliability of the heat exchanger.

Conceptual design of secondary and tertiary circuit for a new nuclear source
Valíček, Roman ; Kracík, Petr (referee) ; Milčák, Pavel (advisor)
The aim of this thesis is to create a conceptual design of the secondary and tertiary circuit of a new nuclear power plant in our country, which is preceded by a brief search of particular generations of nuclear reactors. The VVER-1200 reactor became the model for the new nuclear power plant. There was designed a heat diagram containing primary components in this work. After that, there was the balance calculation and calculation of parameters of the main devices of the proposed scheme such as condenser, low-pressure and high-pressure regeneration exchangers and steam generator.

Turbogenerators in nuclear power plants
Oulehla, Jan ; Kracík, Petr (referee) ; Milčák, Pavel (advisor)
The aim of this thesis is to prove the viability of analytical methods for evaluation of thermodynamical properties of steam in the turbogenerators by calculation and comparison with the real data from NPP Dukovany. Calculation is seconded by a brief introduction to the principle of electricity generation in nuclear power plants and description of primary, secondary and terciary circuit of NPP Dukovany. Substantive part is also analysis of often used turbogenerators and their comparison with those used in classical thermal power stations.

Condenser design of a nuclear power plant
Ondráček, Marek ; Kracík, Petr (referee) ; Milčák, Pavel (advisor)
In the beginning of the bachelor’s thesis is a brief view on nuclear energy. The next part of the thesis presents the principle of Nuclear power plant Dukovany and it explains the primary, secondary and tertiary circuit. In the secondary circuit it describes the condensation system and its most important components. Furthermore, the work focuses on a description and a calculation of the main condenser in Nuclear power plant Dukovany. The calculation focuses on a size of heat transfer surface and observation of condensation parameters when changing operation conditions.

Modernization the Dukovany Nuclear Power Station
Kissler, Martin ; Martinec, Jiří (referee) ; Fiedler, Jan (advisor)
Thesis focuses on a detailed technical description of all important parts of secondary circuit in Dukovany power plant and its connection to other systems of power plant. In thesis are analyzed significant adjustments which have been made during the entire operation of power plant including in particular the actions associated with project called Utilization of project reserves of units EDU. In the main part of the thesis were carried out calculations of the power plant's power for states before and after the modernization and there is also analyzed the impact of individual changes on the whole power plant. These changes are with the entire secondary circuit drawn in the T-s diagram.

Heating of a multifunctional house
Mrlina, Pavel ; Vendlová, Lucie (referee) ; Počinková, Marcela (advisor)
The main content of the bachelor's thesis is the solution of heating for a multifunctional building. The thesis is divided into three parts: theoretical, computational, and design parts. The theoretical part focuses on heat substations. The computational part is dedicated to the design of heating and hot water preparation for the multifunctional building. The building houses a dental hygiene office, administrative spaces, a shop, staff lounges, and storage areas. The building is heated using panel radiators and bench convectors. The heat source is provided by a heat substation connected to a central hot water supply system. The heat substation is thermally independent and is equipped with plate heat exchangers for both the heating system and hot water heating. The design part includes drawings and a technical report. These documents are prepared based on the computational part.
