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.

Simulation of nuclear fuel burn-up during whole fuel cycle
Smola, Luděk ; ČEZ,, Ondřej Zlámal, (referee) ; Katovský, Karel (advisor)
The main goal of this Bachelor’s thesis is to create a long-term kinetics model of a nuclear reactor – model, which simulates changes in nuclear fuel inside the reactor core during reactor operation. As the term long-term suggests, primarily the changes in whole five-year fuel cycle horizon are studied, which stands for changes in concentration of elements contained within fresh fuel as well as origination of new ones (with special focus on higher actinides and plutonium). This mathematical model is created using the MAPLE 14 software. Outputs from the model are displayed graphically and thoroughly analysed, so that comprehensive conclusions of problems can be made. Furthermore, the thesis contains theoretical and informational background that is necessary for understanding all the aspects of the model – historical development of nuclear reactors, their basic types, nuclear fuel description focusing on fuel for pressurized light-water reactors VVER (for which the model is primarily designed), MOX fuel and possibilities of its utilization, and last but not least – selected topics from nuclear physics.

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.
