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.

Design of a building using alternative materials with respect to the requirements for sustainable development
Dvořák, Jakub ; Remeš, Josef (referee) ; Žižková, Nikol (advisor)
This diploma thesis deals with the design of a small family house, which construction uses alternative building materials. The first part of the thesis is devoted to the world, European and Czech legislation related to sustainable development. The concept of ecological construction, which focuses on the possibilities of reducing the negative impacts of construction production on the environment at various stages of construction and on energy, material, water and waste management, is also presented. The thesis also describes advantages and disadvantages of particular solutions. In the second part of the thesis, which based on theoretical knowledge, is the design of a family house from alternative materials worked out. The design of the study in the scale of 1:100 consists of measured floor plan drawings of all storeys, characteristic measured section drawings, layout plans with displayed furniture and equipment, elevation drawings of particular facades, roof drawings and situation design. The drawing part is accompanied by a text part. The processed design is compared to the reference building and then evaluated from the point of view of functional, economic, environmental and social requirements.

Study of the water management in a family house with an application of natural wastewater treatment
Kiszová, Radka ; Kriška-Dunajský, Michal (referee) ; Hyánková, Eva (advisor)
Bachelor thesis focuses on water management in the family house using natural treatment of waste water. Text partially deals with research in the area of treatment and reusing of rain and waste water in the case of a family house. Thesis concentrates on sources of waste water, their division and possibilities of reuse. When talking about waste water, main aim is to explain root waste water treatment. Second half of the text presents complex solution of water management in one particular family house. The actual amount of waste water is calculated for number of five equivalent residents, suggestion of its treatment, accumulation and enumeration of presumed amount of rain water captured. Shared storage is designed for both waste water treatment and rain water. This storage is subsequently used for flushing, washing and garden irrigation.

Methodology for rapid, comprehensive, independent decision-making on the need, effectiveness and interaction of adaptation measures in river basins under climate change
Fischer, Milan ; Zeman, Evžen ; Vizina, A. ; Hanel, M. ; Bernsteinová, Jana ; Tachecí, P. ; Štěpánek, Petr ; Pavlík, P. ; Máca, P. ; Ghisi, Tomáš ; Rapantová, N. ; Bláhová, Monika ; Janál, P. ; Trnka, Miroslav
The aim of the methodology is to present methods for quantifying the impacts of projected climate change on the water balance when applying adaptation measures in the Czech Republic for the next few decades. Adaptation measures should contribute to the sustainability of the water balance in all major user segments of water use and management in the basin. The main principle is the use of hydrological models to transform climate change scenarios into time series of hydrological conditions and to quantify the overall water balance of the basin using different types of adaptation measures and their implementation over time. Special emphasis is placed on the evaluation of combinations of adaptation measures that cannot be analysed by simplified methods. The methodology is designed to search for the optimal combination of adaptation measures in the assessed catchment. The proposed approach eliminates the shortcomings of effectiveness assessment from the perspective of the exclusive user of the water resource, as the evaluation of the effectiveness of adaptation measures is carried out in the form of a multi-criteria analysis of the evaluation of the outputs of the simulation model for predicting the water balance in the whole basin. This methodology can be used to assess different adaptation measures in all basic segments of water users: agriculture, forestry, energy, water management and others.

Methodology for determining the main disturbances in the water management balance and optimizing adaptation measures in the conditions climate change
Fischer, Milan ; Zeman, Evžen ; Vizina, A. ; Hanel, M. ; Bernsteinová, Jana ; Tachecí, P. ; Štěpánek, Petr ; Pavlík, P. ; Máca, P. ; Ghisi, Tomáš ; Rapantová, N. ; Bláhová, Monika ; Janál, P. ; Trnka, Miroslav
Ongoing climate change is causing a global increase in air temperature. While this is leading to an acceleration of the global hydrological cycle, and therefore a global increase in precipitation, the spatiotemporal variability in precipitation is much more complicated. While temperature in the Czech Republic shows a consistently increasing trend similar to that of surrounding countries and the planet as a whole, precipitation can be simplified that long-term averages of annual totals remain and are likely to remain very similar in the coming decades. Rising air temperatures inherently bring increased evaporative demand of the atmosphere and, for the same precipitation, a lower ratio of precipitation to evaporation, i.e. the climatic water balance shows a negative trend.

Studie možností zvýšení retence vody v povodí toku Červenka
Valchářová, Pavlína
The diploma thesis deals with the possibilities of increasing water retention in the Červenka stream basin. The literary research describes the issue of water in the forest landscape, what all has an effect on runoff and what are the ways to improve the retention capacity of the landscape. Furthermore, the natural conditions of the location are analyzed - geomorphology, geology and pedology, climate, hydrology, vegetation and fauna, and anthropogenic influences. On the basis of a field investigation, the current state of the water course, including all objects, is described. The forest road network and forest stands are evaluated. The study is based both on the informational characteristics of the area and on field research. The created design with the possibilities of water retention in the Červenka stream focuses on increasing the waterlogged site as a potential place for building ponds. But also on the forest road network, where the risk of water erosion is high and it is necessary to learn how to manage water better
