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.

Parking house of NPP Dukovany
Marečková, Andrea ; Rosendorf, Aleš (referee) ; Boleslavská, Yvona (advisor) ; Matějka, Libor (advisor)
The subject of the bachelor thesis is to solve the crisis situation of parking at the Dukovany Nuclear Power Plant. Parking areas in front of the company are still the same, but the number of cars is growing rapidly. Therefore, the power plant management decided to solve this situation. Two nearly identical parkades were designed for this area to cover the capacity of 1572 parking spaces. It is a simple design of a 5-storey prefabricated building made of reinforced concrete columns, beams, SPIROLL panels and other elements. For better bracing of the building, the vertical communication cores were designed as monolithic reinforced. The façade of the building consists of a suspended structure fitted with expanded metal, which will help with incoming light and also with the exchange of degraded air in the garages. On the first floor there is a parking space for 142 cars, of which 4 are parking stalls for charging electric cars and 10 stalls for designated handicap parking, all these stalls are located only on the ground floor for easier access of the car owners. In addition to these parking stalls, there are three vertical communication cores with staircases and elevators. At one communication core is also a sanitary facility with toilets for men, women, for people with disabilities and cleaning room. Two ramps are designed for vertical crossing of cars in the middle of the ground plan. Self-service washing boxes and utility room were designed according to requirements. The second and subsequent floors are identical. There are 161 parking stalls on each floor, 4 of them are for charging electric vehicles. There are also sanitary facilities and a utility room. For the safety of pedestrians, the entire parkade is marked with horizontal roads, thanks to which the employees get from their cars to the communication core and out of the building.

Determination of the temperature reactivity coefficient for Nuclear power plant Dukovany
Klíma, Jakub ; Bajgl, Josef (referee) ; Raček, Jiří (advisor)
This thesis deals with the re-determination of the temperature reactivity coefficient of the Nuclear power plant Dukovany, which is measured within the physical test Reheating of the cooling to 260 °C. This paper contains description of the types of nuclear reactors launching, list of tests which are performed during these startings and it also describes methods for determination of temperature reactivity coefficient. Last part of this thesis includes description of programme which was created for determining temperature reactivity coefficient from given files and verification of its calculating methods by statistical test.

Warming and Starting Nuclear Unit up of the Dukovany NPP after the Outage
Ludvík, Lubomír ; Suk, Ladislav (referee) ; Katovský, Karel (advisor)
This thesis deals with the analysis of warming and starting up the nuclear unit of Dukovany NPP after the outage. First part explains the various operating modes of nuclear power plants, specifically operating modes of Dukovany NPP. The following part contains the analysis of heat sources in the primary circuit and also the individual production and consumption of steam by the NPP. The next part deals with division into several points of the warming of the Dukovany NPP. The analysis of warming nuclear unit after a outage is made on the basis of the industry based data, measured in December 2015. The result of the analysis is determination the amount of steam passing from a another nuclear unit, which is following by the own proposal of the external steam source.

Analysis of the secondary circuit of the VVER 440 block
Černý, Michal ; Kracík, Petr (referee) ; Milčák, Pavel (advisor)
The main aim of this thesis is the model design and control the secondary circuit block VVER 440. The search part of my work is a description of the secondary circuit. In the first part of the calculation is performed for the rated secondary circuit. The second calculation part focuses on the calculation circuit of the secondary for the reduced, influenced by shutting down one steam generator.

Starting the electricity system from the dark with the help of EDU
Puchnar, Jiří ; Fejta, Libor (referee) ; Mastný, Petr (advisor)
This bachelor thesis aims to introduce the reader Blackout exercise, which is run annually on nuclear power plant Dukovany. This exercise simulates a situation when there is a loss of power for own consumption and the steps leading to its recovery. Then it focuses how to troubleshoot electrical grid restoration of the Czech Republic with NPPD. This bachelor thesis is divided into two parts. The first part defines the term Blackout, described the involvement of power plant to national grid, output to a substation Slavětice and near power sources. NPPD appliances are divided into categories according to the importance of power. Their classification and ways of feeding during normal operation and for other situations are described in the third chapter of this work. In my work I present options and recovery routes after power failure for own consumption NPPD. Internal and external. The lack of power can cause the risks described in the fifth chapter. At the end of the first part is an example of one possible method to restore power from an external source. The second part focuses on the renewal of electrical grid with NPPD. It aims to describe the configuration of the transmission system, using of island operation and some specific features related to island operation. In this section, I present also some new possibilities for increase of durability and safety of electrical grid CR NPPD. The conclusion summarizes the meaning of Blackout exercise together with the benefits of this work and some recommendations.
