Temperature field analysis of spent fuel cask
Švaříček, Tomáš ; Nerud, Pavel (referee) ; Šen, Hugo (advisor)
The purpose of this thesis is temperature field analysis of spent fuel cask destined for dry buffer storage. Also to show possible ways of solving the difficulties in temperature field analysis, together with definition of simplifying presumptions and boundary conditions. Based on reasonable arguments were designed solving formulas, gained analytic solution of the temperature field and then compare analytical solution with numeric solution from ANSYS in the end of thesis.

Sodium steam generator for experimental stand
Janíček, Martin ; Nerud, Pavel (referee) ; Šen, Hugo (advisor)
This thesis deals with the experimental liquid sodium heated steam generator. The first chapters describe the many aspects that should be taken into account when designing this type of steam generator. Furthermore, is approximated in the proposal the work itself. On the basis of thermal, hydraulic calculation of strength and was chosen one preferred option. In conclusion, the best option is evaluated steam generator sodium-water and the possibility of realization.

The 4th generation of nuclear reactors
Katzer, Milan ; Škvařil, Jan (referee) ; Nerud, Pavel (advisor)
My thesis reviews the particular generations of nuclear reactors. The greatest part of the thesis focuses on the groundbreaking projects of the IV.generation reactors, which should be put into operation in 2030 or later. The individual projects come out from the analysis of the international forum GIF where six revolutionary nuclear reactors were chosen. The last chapter is devoted to the detailed description of one of the chosen reactors and its possible installation in the Czech Republic.

The current state of mining and uranium reserves
Vondra, Marek ; Nerud, Pavel (referee) ; Šnajdárek, Ladislav (advisor)
This bachelor thesis is engaged in current state of uranium mining. It describes development of uranium mining on the area of the Czech Republic from the beginning to current state of mining. There are summarized current uranium reserves in the world, with the most important mining areas included. The treatment of uranium ore is described, with its influence on the environment and the remediation of affected mining area. In the last section, the possible ways of uranium usage in the future are mentioned.

Review of world nuclear reactors
Blažková, Eva ; Nerud, Pavel (referee) ; Šen, Hugo (advisor)
This bachelor work is focused on creating an overview of nuclear reactor types, their categorization and engineering approach to particular designs. Furthermore, it also lists countries having nuclear reactors in possession and their standpoint towards nuclear energy in general. A brief summary of the third and fourth generation and their future energy potential is included as well. This work primarily reflects present-day status.

Improvement of energy supply in industrial process
Pavlíček, Lukáš ; Nerud, Pavel (referee) ; Pospíšil, Jiří (advisor)
The main subjekt of that diploma thesis is an optimalization energetic ekonomy of a bathroom. The ojective is propose suitable resolution for decrease decrement heating and employ outlet heat of burnt gas which are going from steam generator. In the first part of thesis is evaluation inceptive state, inlet and outlet flows of energies. In the next part, there are confront indivudual resolving from technically angle and economically angle.

Thermoelectric Power Generation System
Brázdil, Marian ; Nerud, Pavel (referee) ; Pospíšil, Jiří (advisor)
In the last decade there is a rising interest in thermoelectric applications. Thermoelectric generators enabling the direct conversion of the heat into the electricity become attractive. This fact is caused by the demands of environmental operation and saving primary resources. Scientists intensively investigate and develop new materials and structures suitable for these applications. The efficiency of the thermoelectric conversion progressively increases. Unfortunately we have no available materials with sufficient thermoelectric properties which could provide cost-competitive price. Thermoelectric generators seem to be useable devices. For example, in case of the unused waste heat using of the thermoelectric generator can increase the overall effectiveness of the unit despite the low efficiency of the generator. This master thesis deals with the issue of the Peltier modules representing the main part of the thermoelectric generators. The physical principles and structures of the thermoelectric modules and the possibility of thermoelectric power production are described here. In the practical part of this thesis the design of the low power generator utilizing waste heat from biomass boiler Verner A 251.1 is proposed.

Evaluation of power and coolant flow in reactor core
Tvrdý, Miloslav ; Šen, Hugo (referee) ; Nerud, Pavel (advisor)
This graduation thesis deals with evaluation of power and coolant flow in reactor core. The first part is a description of nuclear power plant VVER 440. It is focused on parts important for transfer and utilize energy in regular operating of generating block. In the second part, the equations for calculation of power and coolant flow in reactor core are deduced. The last part is about designing the program for calculation of published values. There are specified requirements for the program and on the basis of this the source code is written. The parts of code are described. In conclusion of this part, the user's manual is work out. The program is on CD in the annexe.
