Nuclear energy and EU energy security
Ryzhenko, Maksym ; Bič, Josef (advisor) ; Vondrušková, Barbora (referee)
This diploma thesis is dedicated to the future development of nuclear energy in the EU area and its incorporation into the current EU energy policy. The work also focuses on a detailed examination of EU energy policy in terms of energy security of the Member States and throughout the text deals with the role of nuclear power as a determining factor of energy security. The work is divided into two parts - theoretical part (Chapter one) and research part (Chapter two and three). The first chapter of this thesis is devoted to current theoretical approaches to the issue of energy security. The issues of energy security are then examined in the final part of this chapter in terms of integration into the all-embracing EU energy policy. The second chapter provides an analysis of the current energy situation in the European Union as a whole and in individual Member States. All findings are applied with emphasis on the status of nuclear energy in the energy mix. The final chapter summarizes current nuclear energy trends in the EU. In addition, analysis of the opinion polls and government interventions in the field of nuclear energy are provided.

Dukovany nuclear power station. New nuclear plant. Comprehensive geomorphological analysis of closer area
Prachař, I. ; Roštínský, Pavel ; Valenta, J.
Synthesis of geological (structural, tectonic, sedimentological), local geophysical (geoelectric) and geomorphological (topographic arrangement, surface inclination, topolineaments, location of fluvial sediments) data in a close vicinity of both the existing and the newly planned nuclear plants. A detailed geomorphological review was included. The study was elaborated requested by ČEZ corporation (main Czech energetic producer) in connection with the assessment of seismic hazard. It was especially focused on features of respective sections of the Jihlava and Rokytná rivers and on nearby the power station located site of thickest moldavite-bearing deposits (with possible stratigraphic age of Upper Miocene – Lower Pliocene) in Moravia at Dalešice.

The impact of Nuclear Power Plant Temelin on the climate of surrounding area
BARÁTOVÁ, Michaela
BARÁTOVÁ, M. (2012): The impact of Nuclear Power Plant Temelin on the climate of surrounding area. Bachelor Thesis. University of South Bohemia, Pedagogical faculty, Department of Geography. 128 pages Nuclear power plant Temelin is a dominant, which forms silhouette of the Ceskobudejovicka basin. It is a construction, which faces and resists criticism from environmental organizations. Benefit or threat to South Bohemia? Undoubtebly, the area of disputes between politicians of Czech Republic and Austria. This bachelor thesis evaluates especially climate impacts of Nuclear Power Plant Temelin. Theoretical - methodological base is mainly focused on the discussion of literature, in general and in specific terms researched the topic and related hypotheses. General section then describes the basic physical - geographical characteristics of the selected area, special emphasis is placed on climatography. An integral part of the general section is a brief description of working the youngest European power plant. The analytical section is dedicated to monitoring climate of surrounding area ETE using data that was recorded by Observatory Czech Hydrometeorological Office in Temelin and the results are compared with data that were recorded during the same period by in České Budějovice. The monitoring of climate surrounding area of Nuclear Power Plant is assessed from two perspectives. The first view sees the climate before the start of nuclear power plants in operation, so from 1989 to 2001; the second look is focused on changes which was formed after the running of nuclear power plants in 2002. The analytical part shows the possible changes in selected climatic characteristics that could be caused by cooling tower plume.

Study of 137Cs, 90Sr and 3H behaviour in hydrosphere in vicinity of Nuclear Power Plant Temelin
Ivanovová, Diana ; Hanslík, Eduard (advisor) ; Pitter, Pavel (referee) ; Prouza, Zdeněk (referee)
The thesis focuses on an analysis of the results of long-term monitoring of the concentrations of 137Cs, 90Sr and 3H in hydrosphere in the vicinity of Temelín Nuclear Power Plant. The monitoring was carried out during the period 1990-2008 subsequently in several projects, which include Research of impacts of Temelín Nuclear Power Plant on hydrosphere and other components of the environment (National project no. N 03-331-867), Research on impacts of nuclear facilities on the environment (VaV/510/1/96), Strategy and methodology of integrated studies of long-term trends in landscape development in close and wide vicinity of Temelín Nuclear Power Plant (VaV/640/8/03), Programme on monitoring and assessment of impacts of Temelín Nuclear Power Plant on the environment, and Monitoring for Czech Power Works, a.s., Nuclear Power Plant. The thesis was carried out in T. G. Masaryk Water Research Institute, public research institution. The radionuclides were monitored in surface water, river sediments, aquatic flora and fish species. The main objective of the thesis was to analyse and integrate all of the knowledge on concentrations and behaviour of these radionuclides, which originate mainly from residual contamination, in order to assess the impacts of Temelín Nuclear Power Plant (Temelín plant) on...

Nuclear energy in the Czech Republic
Bosáková, Lenka ; Vostrovská, Zdenka (advisor) ; Antoš, Ondřej (referee)
This thesis deals with the topic of nuclear energy. The Czech Republic is currently a net electricity exporter however this status will probably change in next few years because of growing electricity consumption and decommissioning of obsolete coal-fired power plants. Moreover, contemporary government declared that it won't approve any construction of new reactors stressing the importance of renewable sources of energy (in spite of their limited potential in the Czech Republic). The goal of this thesis is to answer the question whether nuclear energy can compete with other sources of energy and whether is it possible to satisfy growing electricity consumption under the conditions of the Czech Republic by any other source of electricity besides nuclear energy taking into account environmental aspects.

Nuclear dynamics and interactions of myosin 1c
Dzijak, Rastislav ; Hozák, Pavel (advisor) ; Hašek, Jiří (referee) ; Kaňka, Jiří (referee)
1. ABSTRACT Myosins are proteins that convert chemical energy stored in ATP into mechanical force that is applied on an actin filament. Nuclear myosin 1 (NM1) was the first myosin detected in the cell nucleus. Together with nuclear actin they were shown to play important roles in DNA transcription and chromatin remodeling. However, the molecular details of the NM1 functions are largely unknown. To expand our knowledge about this molecular motor we studied tissue expression, mechanism of nuclear localization and molecular interactions of this myosin motor. In the first part we examined the expression pattern of NM1 in various mouse tissues. We demonstrated that NM1 is present in cell nuclei of all mouse tissues examined except for cells in terminal stages of spermatogenesis. Quantitative PCR and western blots demonstrated that the expression of NM1 in tissues varies, with the highest levels in the lungs. NM1 is a nuclear isoform of earlier identified myosin 1c (Myo1c), which was described initially as a cytosolic, and plasma membrane associated protein. The only known difference between these two proteins was the presence of additional 16 amino acids at the N-terminus of NM1. Next we focused on the influence of NM1 domains, including the N-terminus, on the subcellular localization of this protein. We found...

Viruses and cytosketelon of the cell nucleus
Cibulka, Jakub ; Forstová, Jitka (advisor) ; Šťovíček, Vratislav (referee)
The nuclear cytoskeleton (the nucleoskeleton) provides a structural integrity to the nucleus and is involved in number of key processes including transcription, chromatin remodelling and mRNA transport. The nucleoskeleton consists of nuclear lamins, nuclear actin and other proteins. Some viruses, which replicate themselves in the nucleus, use nuclear cytoskeleton in their life-cycle. On the other hand the nucleosketon may also represent a barrier for viral infection. Herpesviruses need nuclear actin for capsid assembly and transport, but they have to desintegrate the nuclear lamina in order to escape the nucleus. Nuclear actin also participates in the morphogenesis and probably nuclear export of baculovirus capsids. Some retroviruses transport their unspliced RNAs from the nucleus using nuclear actin and there is also some evidence of retrovirus-induced nuclear lamina disruption. In this work, I focus on the interactions of above-mentioned viruses with the nuclear cytoskeleton (namely nuclear actin and lamins).
