The theme of the diploma thesis is the solution of the pre-plant zone of the Dukovany nuclear power station. Creating a vision of how this space could develop further in the next 50 years and how it could work in a transitional phase during the construction of a new nuclear power plant unit. The subject of the thesis is the elaboration of an architectural study, which is based on an urban study. Urban study was processed within the framework of the pre-diploma thesis and solved mainly the overall problems of this area, the new transport connection, and the functional division of the whole area. The area was divided into three functional units, namely the transport zone, the administrative zone and the sports and education zone. At present, there are a lot of small structurally and functionally unsuitable buildings in this area. The diploma thesis deals with the design of new buildings with a clear functional use in the administrative zone, in the area in front of the main gatehouse. A new representative square was created, and three buildings are designed around it. The dominant feature of the whole area was a high-rise office building near the gatehouse. In front of the office building, towards the main road, the service building I was designed, which contains business and healthcare services. On the other side of the square was located the service building II, where there are technical services, such as workshops, warehouses and metrology. The last building solved within the diploma thesis is the building of sports and locker rooms of suppliers, which is designed behind the square near the greenery. New building copies mass of the only preserved building in this area, namely the building of the information centre. The designed building has a fitness centre and locker rooms of external workers of the power plant.

Manufacture of nut tightening device for reactor cooling pump's impeller
Rygl, Filip ; Slaný, Martin (referee) ; Kalivoda, Milan (advisor)
This thesis solves the problem of design and production of a special mounting device for the impeller nut of the main circulation pump GCN-317. The proposed device is intended to solve the problems associated with the mounting and dismounting of this nut. The work provides basic information about the Dukovany Nuclear Power Plant and VVER-440 systems in general, including their brief history. It also introduces the operational and legislative environment of the primary circuit of the nuclear power plant. It deals with the task and technical description of the main circulation pump and its overhaul. The following sections present the basic principles of construction of the device and an overview of its components with a description of their purpose and method of production. The last part of the thesis describes the function of the device and its verification and reports on its deployment.

Design of The Data Communication Between Digital Protection Relays and Monitoring System of Dukovany Nuclear Power Plant
Šula, Vladimír ; Topolánek, David (referee) ; Toman, Petr (advisor)
This thesis describes the provision of the data communication of the new protection relays via 6 kV switch gears to the electro monitoring system at the Dukovany Nuclear Power Station. These protection relays will replace the current analog protection. The replacement process will start in 2015 and will finish in 2018. Given the overall complexity of the project, this thesis deals only with the following 6 kV switch gears 9BB and 9BD. The thesis is divided into a theoretical and a practical part. The theoretical part concerns the actual consumption and output of the Dukovany Nuclear Power Station. The following chapters describe the electro monitoring system and GRAF and LOGA software programs that are closely connected with it and that were used in the practical part. The last chapter of the theoretical part deals with the actual replacement of the protection relays of the 6 kV switch gears. Also, it describes a new optical network, which will be set up at the Dukovany Nuclear Power Station as a part of the process of replacement. The segment of the practical part concerns laboratory verification of the data communication of the new protection relays. Next, it describes actions that had to be taken in order to ensure and verify correct functionality of the data communication. This part is followed up by a closely related practical activity, which describes examination and verification of the protection functions of each of the 9BB and 9BD switch gears protection relays.

Service operation of nuclear power plants
Krutiš, Petr ; Foral, Štěpán (referee) ; Radil, Lukáš (advisor)
This thesis deals with the service operations that are essential for the smooth running of the Dukovany Nuclear Power Station. The first part describes the nuclear power station with its VVER 440 reactors; it particularly describes basic devices of the primary circuit, which include a nuclear reactor, a steam generator, the main circulating pump, a pressurizer and the main closing fitting. The next chapter concerns water management, whose main objective is pumping crude water and treating it so that it can be used in technological circuits of the power plant as well as in secondary systems, which maintain the required parameters and conditions necessary for the operation of basic devices of the primary circuit. The secondary systems secure compensation of reactivity changes in the reactor. Next, they secure refilling, cleaning and degassing of the coolant. The final part of this Bachelor thesis describes an increase of the electrical output of one of Dukovany's units to 500 MW and its effect on the secondary systems of the primary circuit. The main adjustments before the output increase were performed on secondary circuit devices and electrical devices. Primary circuit's machinery remained unchanged.

The master thesis deals with the facelift of the forecourt of the Dukovany Nuclear Power Station . This space consists of supporting functions for the main working such as administrative, metrology, stocks, cloakrooms and services. There is also the station for the buses, which carry employees to and from work, the regular bus station and parking lots. The forecourt of the power station is now inconvenient from a functional point of view, because the capacity of the existing buildings and parking lots is insufficient; and also from aesthetic point of view, because the buildings from 70’s don’t look good anymore, the parking consists of the large asphalt areas and there is no representative anteroom in front of the main entry, which should be there in view of the significance of the power station. In the study I deal with these problems by the complex reconstruction of the area, I replace the huge asphalt parking lots with the parking houses, create the administrative zone with the public place in front of the main entry to the plant, extend the capacities for the particular functions and add the new required functions (kindergaten, other services). The result of this conversion is the area with the particular functional zones with the representative forecourt in front of the main entry and with the enough space for each of the functions. This work follows up the last semester urbanist-architectonic study. The diploma thesis focus on the improvements of the weaker parts of the prime study and on the elaboration of the architectural study of the adminstrative zone with services.

Czech Public Opinion on Nuclear Energy – August/September 2023
Červenka, Jan ; Ďurďovič, Martin
In its August/Septemer 2023 survey, the Our Society series included a battery of questions on issues of nuclear energy. The survey examined public opinion about whether the proportion of nuclear energy in electricity production should increase or decrease in future, what people think about building a new unit of the Dukovany Nuclear Power Station (DNPS), whether or not they are concerned about the use of nuclear energy in the country, and whether they have confidence in the government’s decisions about the development of nuclear energy.

Czech Public Opinion on Nuclear Energy – Autumn 2022
Červenka, Jan ; Ďurďovič, Martin
In its Autumn 2022 survey, the Our Society series included a battery of questions on issues of nuclear energy. The survey examined public opinion about whether the proportion of nuclear energy in electricity production should increase or decrease in future, what people think about building a new unit of the Dukovany Nuclear Power Station (DNPS), whether or not they are concerned about the use of nuclear energy in the country, and whether they have confidence in the government’s decisions about the development of nuclear energy. A newly included question also asked whether citizens know how the Czech state manages nuclear waste.
