Condenser design of a nuclear power plant
Hejduk, Michal ; Šnajdárek, Ladislav (referee) ; Milčák, Pavel (advisor)
The topic of this master´s thesis is the design of the steam generator for a nuclear power plant with VVER 440 reactor. The first part of this thesis describes a brief history of nuclear research, which is followed by an overview of nuclear reactors used now. The next part deals the types of steam the types of steam generators used today with their basic elements and design recommendations. The last and final part is the design of a steam generator for nuclear power plant with a VVER 440 reactor. Above all, is the thermal calculation of the steam generator and behaviour of steam generator depending on the reactor power. The design solution of steam generator and its strength calculation. The last part of the steam generator calculation the pressure loss of the steam generator is investigated.

Steam turbine start-up
Jelínek, Tomáš ; Kracík, Petr (referee) ; Šnajdárek, Ladislav (advisor)
This bachelor thesis focuses on steam turbine start-up process. The first part of this thesis describes in general terms the basic practices and principles of start-up. The second part deals with the general description of thermal stress on the rotor and stator part. There is also simplified calculation of start-up duration and admissible temperature difference. The last part is a calculation of heat transfer coefficient using inverse heat transfer analysis. There is a comparison of models and measurement data of thermal stress.

Boiling crisis of advanced nuclear fuels
Bírošíková, Martina ; Milčák, Pavel (referee) ; Šnajdárek, Ladislav (advisor)
This diploma thesis deals with a theoretical description of the boiling crisis during intensive heat transfer between the outer surface of the fuel and the coolant and research of the materials and coverage of fuel assemblies with emphasis on the importance of accident tolerant fuel with higher accident resistance. The experimental part ot the work determines the critical heat flux on the examined test sample and interprets the results obtained several times by repeated measurements.

NOx production and elimination content in the flue gas
Čech, Jaroslav ; Šnajdárek, Ladislav (referee) ; Hrnčířová, Michaela (advisor)
The Bachelor thesis deals with oxides of nitrogen, resulting from the combustion process. The thesis is concentrated mainly on the description of the emergence mechanisms and on the various measures that are used to reduce their concentration. Part of the thesis is also focusing on legislation in the field of air protection, with the values of the emission limits valid for the Czech Republic and the European Union.

Equipment for testing of thermoelectric modules
Frank, Vojtěch ; Šnajdárek, Ladislav (referee) ; Pospíšil, Jiří (advisor)
Goal of this thesis is to specify needed upgrades of current aparatus used for measuring parameters of thermoelectic modules, witch was constructed at the Enegry institute of Faculty of Mechanical Engineering, Brno University of Technology. In this theseis current state of aparatus where reviewed and specifications for updates where made. These specifications where used to create plans for new aparatus. Quality of designed aparatus where verified by simulations made in ANSYS. Plans for proposed aparatus where made.

Natural gas expansion unit
Žáček, Ondřej ; Šnajdárek, Ladislav (referee) ; Pospíšil, Jiří (advisor)
The bachelor thesis "Natural gas expansion unit" relates to the problematics of gas pressure reduction from transport network of NET4GAS to the distribution network of JMP Net s.r.o. The thesis consists of three parts. In the first part the reader is introduced to the methods of natural gas pressure reduction, to the behavior and properties of natural gas and to the problematics of pressure levels of the gas pipelines. The second part describes the important segments of the expansion station in Velké Němčice such as the expansion turbine, cogeneration, regulators etc. The third part contains calculation of the most effective operation of the station.

Assessment of investment in heating house
Baláži, Martin ; Šnajdárek, Ladislav (referee) ; Baláš, Marek (advisor)
Bachelor thesis assesses the ways in which you can reduce the cost of heating a house. After the calculation of heat loss, there are chosen appropriate thermal-insulation applications to reduce heat transmission through the facade, roof and windows of the building. In the next step is chosen more efficient and environmentally friendly way of heating. Return on investments of selected applications, are shown graphically.
