Options for Radioactive Waste Disposal
Veličková, Andrea ; Šnajdárek, Ladislav (referee) ; Chýlek, Radomír (advisor)
This work focuses on the analysis of the problem of radioactive waste, its classification and methods for its treatment, storage, and disposal. The work describes options of disposal of radioactive waste and methods for its safe disposal. Waste can be classified by its physical state, half-life, radioactivity level and origin, which determines the appropriate methods for pretreatment, treatment, conditioning, storage, transport, and disposal. Short-lived wastes can be returned to the environment, while long-lived radionuclides must be disposed of in deep geological repositories in salt rock, clay, or granite geological formations. Less dangerous wastes are usually disposed of in surface or near-surface repositories. A comparison of individual disposal options shows that the surface repositories are more economical but less secure than deep geological repositories, which provide long-term isolation. Reprocessing of the spent nuclear fuel, used by advanced nations, requires specialized facility and carries risks. The safe management of the radioactive waste is the key to the peaceful use of nuclear energy. Continued research, innovation and global collaboration are essential for a sustainable future.

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.

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.
