Upgrading the secondary circuit of the Dukovany NPP
Fialová, Michaela ; Fiedler, Jan (referee) ; Šen, Hugo (advisor)
With the ever increasing usage of electric power and decreasing supply of natural resources, there is a growing effort to effectivelly maximise current dispositions of resources. Utilising project reserves at already functioning Nuclear powerplants belongs to these projects. In this article I am going to describe this utilisation and overall modernisation of the Dukovany Nuclear powerplant.

The use of Steam Turbines
Kissler, Martin ; Vojáčková, Jitka (referee) ; Fiedler, Jan (advisor)
The aim of this bachelor’s thesis is to present the development of steam turbines from their construction to the detailed description of one of the major representatives of the modern turbines. The introduction of my thesis focuses on the historical development of the first turbines and their division according to the basic aspects. It is followed by a description of the use of steam turbines to generate electricity, for driving machines and for use in heating plants. The conclusion of my thesis is a detailed description of the turbines located on Nuclear Power Plant. To the description is added a simplified calculation.

Retrofit steam turbine 210 MW
Sedláček, Tomáš ; Fiedler, Jan (referee) ; Kracík, Petr (advisor)
This master‘s thesis deals with the retrofit of a three-body condensing steam turbine with an output of 210 MW. The first part deals with the thermal diagram, which is designed with seven unregulated steam extractions and one extraction for degassing. The mass flow is determined here on the basis of the required power and three thermal diagrams are made for different outputs. In the next part, the regulation stage in the A-wheel design was designed, including the strength control. The main subject is the design of the stage part, which is divided into preliminary and a detailed calculation relating only to the high pressure section of the steam turbine. During the optimization phase, a detailed calculation is linked to the thermal diagram and the regulation stage. The resulting blading of the HP section is optimized based on the selected properties, including strength control. An orientation design of the compensating piston together with the sealing system is also included, for selected diameters, due to the unknown action of the axial force from the MP and LP section. Furthermore, a strength check of the inner nodes of the existing body of the high-pressure section is performed, where the need to use the inner body arises. The designed HP section, including the regulation stage, achieves an internal power of 69,5 MW, an internal thermodynamic efficiency of 92 % and a reheat factor of 1,0168.

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.
