Increased performance turbo machinery in EDU the NPR changing
Bašta, Tomáš ; Kracík, Petr (referee) ; Fiedler, Jan (advisor)
The Diploma thesis on the topic of Increased performance turbomachinery in EDU the NPR changing describes in detail some important devices of technology system of the secondary circuit of Dukovany Nuclear Power Plant together with their task in the thermal circulation. There is a computational model of secondary circuit according to the present thermal schema created in the main part of the thesis. At the end of the thesis, the possibilities of the increase of the terminal power of turbomachinery, specifically of the turbogenerator, by the exhange of low-pressure heaters (NPR) are stated. Obtained results are documented by drawings of the thermal schemes.

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.

Heating of Veterinary Clinic
Marčiš, Šimon ; Topič, Jan (referee) ; Počinková, Marcela (advisor)
This bachelor thesis examines a design of water heating and heating system for Veterinary clinic in Horný Hričov. The theoretical section reviews basic aspects of heat pumps like history, operating principles, types of refrigerants used and basic classification of heat pumps. A specific attention is paid to the brine/water heat pump type which is analyzed in detail. The analytical section of this thesis consists of complete calculation and design of the heating system and water heating. The third section of the thesis comprises a project elaborated to the level of a realization documentation for the construction. The project consists of a technical report and a drawing documentation.

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.
