Evaluation of Power Efficiency of Radioactive Waste Management Technologies Used in the Czech Republic
Penzinger, Pavel ; Varmuža, Jan (referee) ; Katovský, Karel (advisor)
This thesis deals with the evaluation of power efficiency of technologies for the radioactive waste management used in the Czech Republic. Thesis is divided into two main parts – theoretical part and a practical part. Theoretical part of the thesis deals with a brief description of the organization connected with radioactive waste operating in the Czech Republic and storage of low and intermediate level waste in the Czech Republic. This is followed by various kinds of radioactive waste division according to Czech legislation and regulations of the International Atomic Energy Agency. There is also a description of the most used technologies and methods o of radioactive waste management technology used in the Czech Republic and world. Practical part contains specific evaluation of energy efficiency of each technology for the radioactive waste management. Each evaluation contains the energy efficiency of production use materials and transport. Evaluates are technologies used consistently and for sufficient quantities. Energy efficiency is describe from the place of origin of radioactive waste, which is the Nuclear power plant Dukovany, Nuclear power plant Temelín and ÚJV Řež, a.s. The end of description is the repository site of radioactive waste Dukovany for radioactive waste from nuclear power plants or disposal site Richard for institutional radioactive waste.

Transmutation of spent nuclear fuel
Šajdler, Miroslav ; Foral, Štěpán (referee) ; Katovský, Karel (advisor)
This bachelor's thesis deals with spent nuclear fuel – its composition, disposal, reprocessing and transmutation. In the beginning, you can find the classification of radioactive waste, and then I am explaining the policy of the Czech Republic towards disposal of nuclear waste. This is followed by the comparison of the policy in other countries. The thesis also contains various methods used to reprocess spent nuclear waste, composition of spent nuclear waste – based on its radioactivity and radiotoxicity and future technologies for nuclear reprocessing. In the end, I tried to describe a simple model simulating transmutation in light water and fast reactor.

Design modification of the collimator for RAW measuring system
Svoboda, Štěpán ; Lisý, Martin (referee) ; Šen, Hugo (advisor)
This thesis deals with structural design of collimator. Collimator is important component of radioactivity measuring device. This apparatus is made by Envinet. Collimator is part of device, which makes good conditions for measuring radioactivity, protects detector and tries avoid overload detector. In this thesis is dealt simplification of collimator. It supposed, that simplified collimator will be more reliable. This proposal saves more money, because company will not have to send employee of Envinet to service their measuring devices in a very distant countries, such as Russia, Ukraine etc.

Ways of radioactive materials saving in the Czech Republic and in the world
Polák, Luboš ; Šen, Hugo (referee) ; Nerud, Pavel (advisor)
Management of spent nuclear fuel and radioactive waste are many. The aim of this thesis was to summarize the attitude of the Czech Republic and the other major countries on this issue. First is given the classification of radioactive waste according to various criteria. Consequently, it is defined and described the fuel cycle, as the largest producer of all types of radioactive waste. Then is analyzed approach of the Czech Republic to the management of all type radioactive waste and the attitude to deep geological repository. At the end are some, in this respect, major countries and their attitude to deal with spent nuclear fuel, radioactive waste and the method of final disposal.

Logistics of radioactive waste
Knapová, Jitka ; Jirsák, Petr (advisor) ; Jiříček, Karel (referee)
The aim of diploma thesis is to analyse the overall technical base and to monitor logistic processes which are from the very beginning associated with radioactive waste and spent nuclear fuel. The main emphasis is put on spent nuclear fuel from nuclear power plants. The current situation in this area is illustrated by an example of the Czech Republic and Sweden. The comparison of Czech and Swedish system leads to demonstration of strengths and weaknesses of the used methods.

Radioactive wastes and the release of radioactive substances into the environment (learning program)
NOVÁK, Jan
This bachelor thesis, "Radioactive waste and the release of radioactive substances into the environment", is concerned (among others) with nuclear fuel and the biological effects of ionizing radiation. First, it briefly describes the history of this branch in the Czech Republic. Then the work is focused on the effects of ionizing radiation, divided into deterministic and stochastic effects. The work also contains a list of legislative norms regarding the handling of radioactive waste in the Czech Republic and the European Union. Protection of the environment and health against hazardous radioactive waste is at present regulated by several guidelines. The primary objective of this work was to compile a comprehensive basis for presentation to university students on the subject of radioactive waste and its impact on the environment. The concluding discussion presents the author's views on another possible application of e-learning in dealing with this branch of study at the University of South Bohemia.

The system of the safe storing of radioactive waste
NEUMANNOVÁ, Kateřina
We can hardly imagine today{\crq}s modern word of 21st century without usage of nuclear energy and ionizing radiation. We meet them in nuclear energetics, industry, health service and other different fields. Similarly to other human activities even here waste rises {--} radioactive waste which can be dangerous for a man and for the whole environment. Therefore it is very important to deal with it according to existing rules. Radioctive waste rises even in the Czech Republic and that is why an enhanced attention is very necessary here. Therefore I would like to break into these problems as much as I can and I would like to describe these problems in my bachelor work so that everybody is informed about basic information how to deal with radioactive waste in an understandable form. I think that everybody in this country, regardless to their education, should have a basic overview about problems of radioactive waste. I would be very pleased if this bachelor work could help people interested in these problems and if my work is used as an educational material. If readers find new interesting information, my work will be even more useful.

NUCLEAR WASTE AND PROBLEMATICS OF ITS DEPOSITION
Metelková, Michaela ; Ševčík, Miroslav (advisor) ; Lipka, David (referee)
Radioaktivní odpad je nevyužitelný materiál, který pro obsah radionuklidů není možno uvést do životního prostředí. Tato práce je zaměřena především na problematiku likvidace radioaktivního odpadu a s tím související otázku jejího financování. Dále zde nalezneme také legislativní rámec, který omezuje nakládání s radioaktivním odpadem a zároveň určuje komu tento odpad náleží a jaké jsou povinnosti jeho vlastníka. Na radioaktivní odpad je zde také nahlíženo z hlediska negativních externalit. Tato teorie je v této práci dále rozvíjena a to jak po teoretické, tak i po praktické stránce.
