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 diploma thesis deals with the design of a high-speed steam turbine at given parameters provided by G-Team a.s. in Velka Bíteš. The introductory part briefly focuses on historical development of steam turbines, their operational principle and process of energy transformation. In the main part the machinery analysis of high-speed turbines has been carried out. In addition, a preliminary design of the number of turbine stages has been done. Furthermore, a thermodynamic calculation of flow channel for given input and output paramaters has been done together with the conception of construction design and turbogenerator layout. The final part introduces technical comparison of a one-stage and multy-stage high-speed steam turbine.
