Comparison of Nuclear Energy Policy in the Czech Republic and France
Loiseau, Jean-Camille ; Šauer, Petr (advisor) ; Dvořák, Antonín (referee)
This paper studies the nuclear technology and evaluates the most likely technical developments to come until 2030. It examines the features of Czech and French nuclear programs, compares the structures of nuclear sectors and estimates the advantages & drawbacks of further developments in both countries. The paper assesses if certain developments of the nuclear sector in one country can be used in the other country and vice-versa. Finally, proposes a set of recommendations for both countries regarding the development of their nuclear program.
Energetics in Visegrad Group
Horák, Lukáš ; Černá, Iveta (advisor) ; Čajka, Radek (referee)
Main purpose of this thesis is to find out how self sufficient concerning the energy raw materials are countries within Visegrad group. Further purpose of my thesis is to analyse total primary energy supply, the structure of energy supply in countries of Visegrad group and its developments in last 4 decades. Furher I want to reveal how the structure of total primary energy supply and structure of electricity generation reflect the disponibility of raw materials in these countries and transformation of economics in the nineties. A sub-objective of my work will examine how countries of the Visegrad Four use the potential of renewable energy sources and how they support it.
History of mining uranium deposit in Příbram
SASKOVÁ, Klára
The region I´ve chosen for my diploma thesis is situated on the border of Poberounská and Czech-Moravian system of geomorphological unit Bohemian Massif. It used to be one of the richest uranium mining district of Příbram region, and it is characterized by geological structure of central-Bohemian plutonium within the geological complex Bohemian Massif. On the contiguity of it there is found vast hydrothermal uranium deposit. This deposit is divided into 9 panels ? Třebsko, Kamenná, Lešetice, Brod, Jeruzalém, Háje, Svatá Hora, Bytíz, Skalka and Obořiště, which belong to the Příbram district. The town Příbram is famous for its long-standing mining tradition not only of polymetalic but above all of uranium ores. This tradition achieved the great success of world standards in the second half of the 20th century. There was revealed a lot of hydrothermal dikes containing requested uranite (black blende, nasturan) after the Second World War. This raw material was heading to Soviet Union. Uranium mining works initiated its epoch in 1949 and regular mining activities finished by the closing of the last shaft in 1991. In all the period of time there was mined 50200, 8 tones of uranium ore. Uranium deposit in Příbram can also take pride in the deepest shaft No. 16 with the depth of 1838, 4 m which is the shaft No. 16. In connection with the mining there was formed the life of local people and also the life of people from all Czechoslovakia who were setting off to seek a living there. Today all the shafts are closed and deluged in a natural way. In certain area of the deposit has been built cavern gas reservoir. No other mining will be possible in the future. The state enterprise Diamo realizes revitalization works on former mining panels and monitors the value of surrounding environment.
Protection of workers, inhabitants and environment during mining and processing of uranium ore
PILECKÁ, Eliška
In the Czech republic uranium had been mined in Jáchymov (till 1967), near Příbram (1948 {--} 1991), in Okrouhlá Radouň in the south of Bohemia (1972 {--} 1990), near Vítkov in the west of Bohemia (till 1991), in Zadní Chodov (till 1992), in Dyleň (till 1994), in Hamr and Křížany near Stráž under Ralsko (till 1990), in Zálesí in Rychlebské Mountain and in many other locations. The mining of uranium influenced in considerable way health and quality of miners´ lives, and also lives of their relatives and up to now it still influencing quality of lives of people living near mining locations. Above all the uranium industry made irreparable changes in our country and the leftovers are up to now influencing the quality of our environment. That´s why there is a must to pay special attention to this area. Nowadays in the Czech republic there is registered around 3768 old uranium mines, out of it there is 2523 mining cannons which are obliged to be regularly controlled. The negative influences are marked as old burdens of already eliminated mining or modificating act on our environment or in some other way threatening public interests. According to the character of negative expression we distinguish mining burdens, it means negative influence of mining activity on stableness of the surface, and ecological burdens, it means negative influence on our environment. In my opinion a matter of uranium industry is very rarely known to the wide public. The main reason why is it like this can be the fact that in the period of main expansion of uranium industry in the Czech republic all the information connected to the research, mining or maintaining of uranium, were top secret. The second reason can be no existence of complete source of information that could be used for study purposes and the same time for informing general public. That is why this study should purvey such source.
Characterization of a new 8-hydroxyquinoline modifed resin gel for DGT technique
Gregušová, Michaela ; Dočekal, Bohumil
This study deals with a new resin gel based on Spheron-Oxin® ion exchanger with anchored specific groups of 8-hydroxyquinoline for DGT technique. The performance of this new binding phase was tested for determination of Cd, Cu, Ni, Pb and U under laboratory conditions. The new binding phase with a higher selectivity to race metal species than Chelex 100 could potentially provide more information on metals speciation in aquatic systems.
Natural radioactivity of granitoids of the Žulová pluton
René, Miloš
Concentrations of natural radioactive elements (U, Th, K) measured using a field gamma-spectrometry show reletively high variability of chemical composition of granites of the Žulová pluton. The high content of Th is connected with a monazite and allanite contents.
Evolution of ore-forming fluids along the Rožná-Olší shear zone, Bohemian Massif, Czech Republic: Implications for local uranium deposition and comparison with U-mineralization at Schlema, Erzgebirge, Germany
Hein, U. ; Lehman, B. ; Kříbek, B. ; René, Miloš
The late-Variscan primary uranium mineralization was precipitated from low-salinity aqueous solutions at epithermal conditions. The overall temporal evolution of the ore forming fluids is identical with that of polymetallic vein-type systems in large parts of Western and Central Europe.
The distribution of REE-U-Th in hydrothermally altered rocks at the Rožná uranium deposit, Czech Republic
René, Miloš
Distribution of REE, U, Th in hydrothermally altered metamoephic rocks at the Rožná uranium deposit is controlled by various alterations. Compared to unaltered rocks, the most important changes in U, Th and REE contents were found in mineralised albite-rich and carbonate-rich episyenites.
Bioakumulace uranu z kontaminované vody při užití Saccharomyces cerevisiae
Podracká, Eva ; Popa, K. ; Novák, Jaroslav ; Tykva, Richard
Liquid scintillation spectrometry as well as semiconductor and scintillation gamma spectrometry were used for estimation of the bioaccumulation of uranium from wastewater using different yeast strains Saccharomyces cerevisiae
The changes in the localization of the extractive industry and the political consequences.
Novosadová, Monika ; Vošta, Milan (advisor) ; Kašpar, Václav (referee)
The bachelor thesis analyzes the global changes in the territorial structure of the extraction of the mineral resources, especially the energy resources and less some precious metals and diamonds and related political consequences. This bachelor thesis describes also the importance of these resources for human society and their deposits. There are also outlined possible future development of the extraction of these resources. The first chapter illustrates general characteristic of the extractive industry. It introduces the ranking of the extractive industry, main mining regions and the biggest producers of some minerals. The second chapter closely presents energy resources, i. e. mining of energy resources, their deposits, their usage and possible future developments. The third chapter focuses on the mineral resources, i. e. their extraction, deposits, usage and possible future trends. The fourth chapter introduces the political consequences related with global changes in the territorial structure of the extraction of the mineral resources.
