Power and Temperature Coefficient During Nuclear Power Unit Operation
Smetana, Jan ; Vojáčková, Jitka (referee) ; Katovský, Karel (advisor)
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.

Nuclear Fuel Loading Patterns at VVER Reactor Based Nuclear Power Plants
Šajdler, Miroslav ; Vojáčková, Jitka (referee) ; Katovský, Karel (advisor)
The Master's thesis focuses on loading patterns of nuclear reactors VVER. It describes the whole process of fuel cycle, since production to storage or reprocessing. The author puts emphasise on the middle part of fuel cycle in Czech nuclear power plants - Dukovany and Temelín and he also explains which fuels are used in both power plants now and which were used in history. The thesis also contains a basic overview of approaches to loading patterns optimisation in foreign countries. The final part of the thesis discusses practical calculation of loading patterns in the Block III of Nuclear power plant Dukovany, by using optimisation programme Athena and Moby-Dick macrocode.

Nuclear Fuel Loading Patterns Optimization at VVER Reactor Based Nuclear Power Plants
Šajdler, Miroslav ; Vojáčková, Jitka (referee) ; Katovský, Karel (advisor)
This Master’s thesis deals with optimization of loading patterns of nuclear reactors VVER. In the thesis is described the process of both types of fuel cycle – the closed and the open one. The middle part of fuel cycle containing the optimization process represents the crucial part of the thesis. The thesis is focused on the fuel cycles of the nuclear power plant Dukovany. The problem of the optimization is solved by using different programs. In the final part of the thesis, the program Athena for the loading patterns optimation is explained by a practical calculation for different versions of Moby-Dick macrocode and the calculated values for the optimization of the third unit of the nuclear power plant Dukovany are compared.

Power and Temperature Distribution in Nuclear Fuel Assemblies of VVER-440 reactor at Dukovany NPP
Smola, Luděk ; Novotný, Filip (referee) ; Katovský, Karel (advisor)
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.

Computation analysis of the VVER-440 nuclear power reactor core
Máca, Pavel ; Šnajdárek, Ladislav (referee) ; Katovský, Karel (advisor)
This thesis is focused on effect of fuel assembly rotation on the reactor core optimization in VVER-440 reactor. In the first part of this thesis, a brief description and main parameters of VVER-440 reactor are introduced. Next chapter is focused on the Dukovany NPP reactor core design, where these reactors are in operation, together with evolution of used fuel assemblies and reactor core design optimization. The practical part of this thesis includes a comparison of reactor core design optimization with and without fuel assemblies‘ rotation. Furthermore, a so-called multiple rotation method is investigated, which could be more suitable compared to the currently used one.

Interpreting Narrative Techniques in Moby-Dick
Sedláček, Martin ; Procházka, Martin (advisor) ; Robbins, David Lee (referee)
Thesis Abstract The objective of this thesis is to map the narrative strategies of Herman Melville's Moby-Dick. By applying different narrative theories to Moby-Dick, it explores and assesses mainly the narrative reliability (Wayne C. Booth) and the narrative situation (Franz K. Stanzel). Ishmael is generally considered to be an example of an unreliable narrator and in this thesis manifestations of his unreliability are evaluated. Special attention is devoted to the inconsistencies in the narrative (e.g. recurring disappearances of Ishmael, shifts in focus on some of the characters, complete disappearances of other characters) and their treatment, taking the general academic consensus into account. Such phenomena are discussed as deliberately and consciously incorporated into the narrative, rather than being a result of a precipitated writing process. Apart from the formal inconsistencies, the narrative also includes incongruities of thematic nature (e.g. questionable value-scheme according to Rimmon- Kenan). By employing Stanzel's narrative theory, the thesis discusses Ishmael's oscillation between "narrator" and "reflector," with special focus on the dramatic chapters. Using both of these conceptions, Moby-Dick is assessed from two different perspectives, hopefully shedding some light on the complex...
