Characteristics of fan cooling towers
Joska, Jakub ; Milčák, Pavel (referee) ; Pospíšil, Jiří (advisor)
This diploma thesis deals with the problematics of fan cooling towers. The very first part of the text is research, focusing mainly on the theory of cooling and the function of fan cooling towers in general. The following chapter deals with the water resource management of the Dukovany nuclear power plant and the specification of its objects of forced draft cooling towers. The second part describes a computational model created to determine the cooling performance of these towers under the given input conditions. In the following chapters, the results from the computational model are compared with the available data from warranty measurements and with the provided characteristics. The final pages deal with the study of the influence of changes in input parameters on the cooling performance and the research of the behavior of the cooling towers under extreme weather conditions.

Nanotechnology utilization in nuclear industry and research
Skalička, Jiří ; Štefánik, Milan (referee) ; Katovský, Karel (advisor)
This thesis introduces reader to current knowledge of nanomaterials and their usage. It summarises production methods and usage of different materials in nuclear power plants, nuclear research and nuclear medicine. Theoretical part of this thesis is dedicated to possible usage of carbon nanotubes for neutron beam collimation and guides. In experimental part different materials were tested in measuring box connected to horizontal radial channel of VR-1 nuclear reactor and their influence on neutron flux was measured. Tested samples were non-oriented carbon nanotubes, carbon nanofibers, alumina nanowires, oriented carbon nanotubes with several angles of rotation and these samples were compared with results of graphite.

Conventional and small modular reactors
Vintr, Lukáš ; Lisá, Hana (referee) ; Milčák, Pavel (advisor)
This thesis deals with nuclear energy. It contains a brief history of the development of this industry and provides insight into the process and control of the fission chain reaction used in nuclear reactors. It also describes conventional reactor types and the current state of their use in the world. It then mentions the research objectives set by the Generation IV International forum. Finally, it defines small modular reactors, describes a number of conceptual designs, and presents an analysis of the current state of their development, together with the possibilities of their use for the production of electricity or process heat.

Comparison of the concept nuclear power plants feedwater heaters
Špaček, Michal ; Kracík, Petr (referee) ; Milčák, Pavel (advisor)
The topic of this master thesis is comparison of the concept nuclear power plants feedwater heaters. At the beginning, a brief recherche is written in which the types of nuclear reactors and the heat regeneration system are described. In the next part of the thesis, the heat balance diagram of the nuclear power plant is proposed and the parameters found in the design are further used for the thermal calculation of the feedwater heater of low and high pressure regeneration. The thermal calculation is performed for both horizontal and vertical designs. Finally, a basic dimensional design is made for both designs and these designs are compared with each other.

Civilian Nuclear Energy Adoption in Sub Saharan Africa: A Human Security-Based Thematic Analysis of the Discourse on Nuclear Power Production adoption in Ghana
Mwenda, Lewis Kimathi ; Střítecký, Vít (advisor) ; Schlotti, Jivanta (referee) ; Berg, Julie (referee)
[Civilian Nuclear Energy Adoption in Sub Saharan Africa: A Human Security-based Thematic Analysis of the Discourse on Nuclear Power Production adoption in Ghana] ABSTRACT This research paper will explore the different theoretical frameworks gathered from different academic backgrounds that guide and explain the role, function and impact of technological advancement, energy security and nuclear power production. It will note the significance of the 'public sphere' and discourse therein which signifies an energy transition. Further, it will propose a security based theoretical framework as an a priori basis for a thematic analysis of the discourse of nuclear power production adoption in Ghana. It addresses the general question of technological innovation and its relation to society beginning with a traditional view of technological determinism, social determinism and a more complex understanding of socio-energy systems. The paper takes a nod to the complex relational aspects in the technology lifecycle from inception to implementation. It contends that energy transitions therefore require apt participation from all corners of society and ought not to be treated as policy 'black-box, but a process that can be opened up for scrutiny by the public. Moreover, the presentation of these ideas proposes that civilian...
