Role of Czech NPP within grid power regulation
Kostečka, Jan ; Martinec, Jiří (referee) ; Katovský, Karel (advisor)
The aim of the Bachelor’s thesis is the involvement of Czech nuclear power plants in the Czech energy networks, but also in the European Network and their adaptation. Effect of expansion of renewable electrical energy produces the asymmetry in the network and places formed with an excess of electrical energy and places with lack of electrical energy. Flows of electric energy can affect the security and safety of distribution lines. Excessive overloading can cause them to collapse. Therefore, this work is focused on solutions and avoids this problem and minimizes this potential damage. However, the impact of energy revolution has a giant proportion about these overflows network energy. Uncontrollable wind and solar power source may create regionally region surge and flow of this energy goes to areas with shortages of electrical power. The regulation has an impact on fuel. This renegade production could extend fuel cycle, or expand the campaign to more years at least a year. The calculations can show the amount of fuel that can still be used, and thereby increase the yield and economic benefit conditions for extending the life of the reactor units.

Analysis of possibilities for use of III. and IV. generation of nuclear reactors for the Czech Republic
Gajdzica, Lukáš ; Kopřiva, Radek (referee) ; Kopřiva, Radek (referee) ; Matal, Oldřich (advisor)
The thesis deals with the analysis of possibilities for use of III. and IV. generation of nuclear reactors for the Czech Republic. Introduction deals with basic principles of nuclear energetics and fuel cycle which is closely associated with the issue and its development and application in practice will have a significant effect both for choice of future types of nuclear reactors of IV. generation and the matter of settlement with spent nuclear fuel. In other parts the thesis deals with the present state of nuclear energetics in the Czech Republic, compares concrete chosen types of nuclear power plants of III. generation and generally describes nuclear reactors and power plants of IV. generation. Final part of the work is focused on questions concerning the possibility of construction of new blocks of nuclear power plants in the Czech Republic and presents concrete recommendation from author´s point of view.

Ecological problems energetics CR
Šilar, Martin ; Bok, Jaromír (referee) ; Matoušek, Antonín (advisor)
This project presents the current status of power resources and supply in the Czech Republic and examines its different connections with ecology. The existing situation in energetics is described in the first chapter of the thesis. This chapter contains general information as well as an analysis of the progress to date related to the structure of installed power and to the amount of electricity generation and their consumption. The description of the common influence of energetics on the environment is provided in the following chapter, which also introduces the next step, namely a short survey of the characteristics of the currently used energy resources and their direct relationship to the monitored ecological problems. The practical part of the project is based on the calculation of emission in the fifteen biggest thermal power station in the Czech Republic. The calculated amounts of emission are compared with the related features of nuclear waste. The last chapter contains information about the EU legislation concerning the reduction of carbon dioxide. In this respect, there are presented also the measures planned to facilitate the reduction of carbon dioxide in Czech Republic.

Intermediate heat exchanger natrium - natrium
Kupčík, Petr ; Martinec, Jiří (referee) ; Šen, Hugo (advisor)
This paper deals with intermediate heat exchangers in nuclear power plants. First section of this paper is devoted to analysis and divide of construction designs of intermediate heat exchangers in commercial and experimental power plants. There is a description of thermal, hydraulic and strength calculations during projection of IHX in the second chapter. There has been made a blueprint of loop type IHX in the final chapter of this paper.

Ecology and law
Koubalíková, Jitka ; Spirit, Michal (advisor) ; Neděla, Radek (referee)
The thesis deals with the relationship between ecology and law in nuclear energy and the possible impact on the environment. The first part briefly summarizes the most important historical approaches to ecology and describes environmental law in the Czech Republic and the EU. The next section is focused on law in the area of construction and operation of nuclear power plants in the Czech Republic and the EU. The fourth chapter deals with operation of nuclear power plant Temelín and assessment the legislation. The fifth chapter is dedicated to various forms of longstanding conflict between the Czech Republic and Austria.
