Simulation of Accelerator Driven Nuclear Reactor for Spent Nuclear Fuel Transmutation
Jarchovský, Petr ; Ing. Antonín Krása, Ph.D., SCK.CEN Mol (referee) ; Katovský, Karel (advisor)
This master’s thesis deals with usage of burn-up (spent) nuclear fuel in nuclear power plants of next generation – accelerator driven transmutation plants which is produced in current nuclear power plants. This system could significantly reduce the volume of dangerous long-lived radioisotopes and moreover they would be able to take advantage of its great energy potential due to fast neutron spectrum. In the introduction are listed basic knowledge and aspects of spent nuclear fuel along with its reprocessing and the possibility of further use while minimizing environmental impact. As another point detailed description of accelerator driven systems is described together with its basic components. In addition this search is followed by individual chronological enumeration of projects of global significance concerning their current development. Emphasis is placed on SAD and MYRRHA projects, which are used like base for calculations. This last, computational part, deals with the creation of the geometry of subcritical transmutation reactor driven by accelerator and subsequent evaluation which assembly is the most effective for transmutation and energy purposes along with changing of target, nuclear fuel and coolant/moderator.

Accelerator Driven Nuclear Power Plants
Jarchovský, Petr ; Krása,, Antonín (referee) ; Katovský, Karel (advisor)
This bachelor’s thesis deals with utilization of spent nuclear fuel in nuclear power plants of new generation – accelerator driven nuclear power plants and of conversion of this fuel into electrical energy. In the introduction are listed basic physical and theoretical knowledge of nuclear reactors along with their basic division and global distribution. As another point accelerator driven systems are described with their brief development and the basic concept and usage on both the nuclear power plants and transmutation technologies. Some global projects are mentioned here dealing with this system and conduct research. More into detail is point about European projects MYRRHA and ESS, because there are important research facilities worldwide. The next are projects with liquid target as a very promising medium. The last part deals with the calculation of basic parameters of ADS in the MCNPX and its applying.

Compressors in cooling circuits
Řehánek, Matěj ; Hejčík, Jiří (referee) ; Tuhovčák, Ján (advisor)
The bachelor work focuses on carrying out a search of compressors in cooling circuits. This work describes the functions of individual types of the compressors and main advantages and disadvantages are listed there. These facts are then implemented in a mutual comparison and evaluation of efficiency of the compressors.

Condensing steam turbine
Trávníček, Zdeněk ; Fiedler, Jan (referee) ; Kracík, Petr (advisor)
The aim of the master’s thesis is to design a condensing steam turbine based on given inputs. Firstly, a design and computation of heat balance is made, followed by thermodynamic calculation of steam turbine channel and a design of compensatory piston of axial forces. Last part of the thesis consists of a review of a change of cooling water temperature in condensator on last turbine stages. The structural drawing of longitudinal section of turbine is included as well.

Cooling systems in buildings multipurpose buildings
Hobza, Lukáš ; Vlček, Petr (referee) ; Formánek, Marian (advisor)
This Bachelor Thesis deals with cooling systems of housing units and an adjacent wine shop. The theoretical part of the thesis is focused on the principle of working ordinarily used cooling systems and options of productions of cold. The thesis describes advantages and disadvantages of individual systems. The result of the computational part is a design of the optimal cooling system for the multifunctional building which secures a diversion of a thermal load in a summer season and the overall design of the cooling system.
