This Master’s thesis focuses on calculation of power and temperature distribution in fuel assemblies of VVER-440 reactor at Dukovany Nuclear Power Plant. Theoretical section contains a brief description of VVER-440 technology, fuel and its development at Dukovany Nuclear Power Plant, basics of heat generation in nuclear reactors as well as an overview and categorization of computer codes, used for core calculations. Of these codes, the MOBY-DICK computer code is then described in depth, including its input and output files. The MOBY-DICK code is later on used for pinwise calculating power distribution of selected fuel cycles of defined units at Dukovany Nuclear Power Plant, with vizualization of output values for characteristic fuel assemblies. Results of this computation are then used for analysis, whether uneven power distribution in the core and heat generation gradient within fuel assemblies have any influence on measuring channel output temperatures, which is the pivotal part of this thesis.

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.

This master thesis deals with the possibilities of traffic of nuclear power unit at thermal and power effect at the end of the campaign, focusing on VVER reactors. For a better idea of the reader the design of key components of the unit in terms of performance is analysed. Parameters of relevant components for Dukovany NPP are presented briefly. The possibilities of traffic of nuclear power unit on thermal and power effect at the end of the campaign are particularly demonstrated on the example of the Dukovany NPP. Furthermore the program Moby-Dick is introduced and the basic possibilities for its use to calculate the course of the campaign are described. At the end of the thesis, we conducted sample calculations for the duration of the campaign on the fourth block of the nuclear power plant.

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.

This Master´s thesis deals with the coordination and the order of interventions during the appearance of a major accident due to a blackout. It describes in detail the chronology and the priorities of what the shift engineer should do when working on the self-consumption restoration. Furthermore, it gives the variants for determination of the batch of radiation people are obtained by, while working on the self-consumption restoration.

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.

This Master's thesis dealt with securitization attempts related to the planned construction of a new reactor at the Dukovany NPP. Therefore, its aim was to find, analyse and explain securitization speech acts associated with the planned reactor, in the period from summer 2015 to December 2020 using the critical discourse analysis approach. The results show that securitization speech acts of this kind do appear in the Czech public sphere and are articulated mainly by four groups of actors: representatives of Austria, Czech environmental NGOs, Czech governmental representatives, and Czech political opposition. These actors have different goals: to stop the construction of the reactor, to implement the construction of the reactor, or to influence the way in which the construction will be implemented. One case of successful securitization was found in the outcome: The Czech government was able to enforce extraordinary measures that deviated from standard democratic processes using security-based arguments. Their goal was to implement the construction of the reactor. It remains to add that the research also revealed three important functional actors who co-created the discourse: the BIS secret service, the SÚJB nuclear safety office and the company ČEZ.

The subject of the diploma thesis is an architectural study of the forecourt of the Dukovany Nuclear Power Station. The project is based on a pre-diploma project which aimed to develop an urban concept. At the moment the buildings in the area are in an unsuitable condition from a construction - technical and architectural perspective. The urban-architectural study was intended to create a new concept for the forecourt and simultaneously enable its efficient operation in case of the completion of a new nuclear unit. The concept of the solution is based on the removal of outdated buildings and their replacement with new buildings which will meet the current requirements of the Dukovany Nuclear Power Station. From the current layout the main roads, the gatehouse, the information center and the greenery will be preserved. After removing the selected buildings, the renovation area will be divided into the main axes on which the main road network will be designed. The unsuitable connection to public road infrastructure will be solved by minimizing the entrances to the area to two entrances and by moving the suburban bus station from the main road. After connecting the whole area by roads, the area will be divided into functional areas. In front of the gatehouse there will be a square surrounded by public services, an administrative building and by the preserved information center building. From this space, the main representative space of the entire complex will be created. Warehouses and workshops will be located behind the square. Transport areas will be located at the rear of the complex. Thanks to this location, there will be a good connection with the current factory and also with the planned completion of the new nuclear unit on the west of the area. There will also be educational and sport facilities in the complex. The kindergarten will be oriented towards the preserved greenery.

This dissertation deals with the idea of annexing a new nuclear resource in the locality of the Dukovany Nuclear Power Plant and the way of its connection to the power system. The main aim of this dissertation is to design concrete solution of the connection of the new resource to a certain point of the power system and complete this design by means of chosen calculation. According to the task, this dissertation consists of three parts. The first part describes the current engineering solution of the main one line diagram of our two existing nuclear power plants and generally of chosen types of power plants abroad, too. There is also a design of the internal consumption of the nuclear power plants. The objective of the second part of this dissertation is to present the survey of the power and dispositional variants of the new resource in view and mainly assess general possibilities of its connection. Using all information from the preceding part, the third part presents the concrete design of the engineering solution of the connection of the new resource to the power system and also the calculation of parameters of block transmission line. Another dissertation named “Study of Slavětice Distribution Substation Enlargement for EDU New Resources“ concurs this part or more precisely, my dissertation as a whole . For my dissertation I have used some materials and information from the ČEZ Corporation which are confidential. I have also used some knowledge from the analysis from the EGÚ Brno Corporation. This dissertation neither represents nor substitutes a complex analysis of all aspects of a new nuclear resource in the Dukovany Nuclear Power Plant.
