Environmental aspects of steam-gas power station Červený Mlýn
Šilar, Martin ; Kulichová, Lucie (referee) ; Matoušek, Antonín (advisor)
The master’s thesis deals with the environmental aspects of combined heat and power station Červený Mlýn (Red Mill). The introductory part of the thesis focuses on the current production technology and the electricity balance of the power station. The heat and power station (also called combined cycle heat and power plant) is scrutinized in terms of emissions sources, focusing on pollutant emissions to air in the following chapter. In this part of the thesis the quantities of the released emissions, namely solid particulate matter (TZL), sulfur dioxide (SO2), carbon dioxide (CO2) are also calculated. The calculation is worked out according to the valid Czech legislation. Further on, the current production technology of the power station is compared with the best available technologies according to the valid directive 2008/1/EC of the European Parliament and of the Council concerning integrated pollution prevention and control. The last chapter presents the innovative technologies which could possibly be installed to reduce pollution emissions (especially nitrogen oxides - NOx) to air at the heat and power station Červený Mlýn.

Connecting of the Photovoltaic Power Sources to the Distibution Network
Ondroušek, Luděk ; Ing.Pavel Veselka (referee) ; Matoušek, Antonín (advisor)
This work is focused on the current issues, which are associated with the connection of fotovoltaic sources to the distribution grids. An example of these problems can be the connection of the bigger fotovoltaic power plant to the part of the grid with small short-circuit power. In consequence of this, it can happen that the quality parameters (voltage) of this grid are undesiderably influenced. Integral part of the connection procedure of the new sources to the grid is also a design and method of the power output, which is also part of this work.

New Resources Connection Analysis to Power System
Galuszka, Jakub ; Ing. Pavel Štěpánek - ČEZ a.s.- EDU (referee) ; Matoušek, Antonín (advisor)
This dissertation deals with the idea of annexing a new nuclear resource in the locality of the Dukovany Nuclear Power Plant and the way of its connection to the power system. The main aim of this dissertation is to design concrete solution of the connection of the new resource to a certain point of the power system and complete this design by means of chosen calculation. According to the task, this dissertation consists of three parts. The first part describes the current engineering solution of the main one line diagram of our two existing nuclear power plants and generally of chosen types of power plants abroad, too. There is also a design of the internal consumption of the nuclear power plants. The objective of the second part of this dissertation is to present the survey of the power and dispositional variants of the new resource in view and mainly assess general possibilities of its connection. Using all information from the preceding part, the third part presents the concrete design of the engineering solution of the connection of the new resource to the power system and also the calculation of parameters of block transmission line. Another dissertation named “Study of Slavětice Distribution Substation Enlargement for EDU New Resources“ concurs this part or more precisely, my dissertation as a whole . For my dissertation I have used some materials and information from the ČEZ Corporation which are confidential. I have also used some knowledge from the analysis from the EGÚ Brno Corporation. This dissertation neither represents nor substitutes a complex analysis of all aspects of a new nuclear resource in the Dukovany Nuclear Power Plant.

In my master thesis I focus on evaluation of gas emissions from the Nuclear Power Station (NPS) Dukovany. My goal is to judge a fulfilment of czech legislative demands and Euratom “Commison recommendation on standartised information on radioactive airborne and liquid discharges into the environment form nuclear power reactors in normal operation” by operator of the NPS Dukovany. I give an acount of resources of gas radioaktive waste in the NPS Dukovany, methods of their cleaning and monitoring in air-conditioning systems in the NPS. Moreover, I sumarize czech legislative demands on monitoring of gas emissions from nuclear power stations and valide decisions of State Office for Nuclear Safety (SONS) for discharges of radionuclids from NPS Dukovany into environment, where autorised limits for gas emissions into atmosphere are set. In the folowing part of the thesis, I describe separate elements bound for monitoring of gas emissions, including technical parameters of individual measuring instruments. Sumary of radioactive emissions to athmosphere during 2007 and sumary of emissions within last 10 years are also included. Finaly, I deal with an analysis on the fulfilment of Euratom Commission demands for monitoring of gas emissions in the NPS Dukovany and I evaluate imperfections to be found during the proces of monitoring of gas emissions from the NPS Dukovany and I make some recommendatios for their correction and improvement of the monitoring. In conclusion, the NPS Dukovany fulfils demands of the czech legislation and decisions of SONS in the field of monitoring of gas emissions into atmosphere. The NPS Dukovany is aware of above mentioned imperfections and focuses on up-dating of measuring instruments in the course of investments, which are under preparation.
