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.

Study of the small water power plant which is situated in the middle and lower reach of river Morava
Dočkal, Jiří ; Malý, Jiří (referee) ; Matoušek, Antonín (advisor)
The present thesis deals with the description of the current state on the course of Morava river from small hydro Kromeriz after a small water plant Hodonin. Subsequently, I deal with the description of search of weir plants and weirs for the construction of small hydropower (especially their heads, structures and, where appropriate, possible adaptation). Then I deal with completion new hydroelectric plants on this founded weir plants and weirs which are in section between the small hydroelectric power Kromeriz and Lanžhot city on the Czech Republic side (Brodské on the Slovak Republic side). In this work is mainly focus on the calculation of installed performance in individual locations (and also the calculation of achievable performance in these locations), machinery design (for the use of selected sets from Hydrohrom company) and the way the configuration of the power switch. If it is in those places, řeším even more possibilities of this construction is splavnění view of the river, especially in the field of Hodonin - Lanžhot. In addition, deals with the design of line side cubicle of each switch to local distribution networks (draft routes). In the last phase deals with the size of the production in each generation, calculations of costs of constructing these plants, approximate calculation of the production (of the flows of 2007) and time of return on your investment in the construction.

Renewable resources of energy in Czech Republic
Trachta, Jiří ; Mastný, Petr (referee) ; Matoušek, Antonín (advisor)
The aim of the present thesis is the introduction of the issue of biomass and of its usage in the Czech Republic. The international of biomass growing as well as the waste product usage are discussed. The waste products are turned into biomass instead of being simply thrown away or burnt down. As far as the renewable resources are concered the Czech Republic is only at the begining. It is important to pay attention to the renewable resources as the amount of fossil fuels (coal, oil, gas) has been decreasing considerably. There are a few green alternative sources that are possible to be used in the Czech Republic. The biggest eletrical energy supplier in the Czech Republic, the ČEZ Company, has decided to start using water power stations in the future. Water energy has been increasingly used by hydro elektric power plants and booster power plant. Also wind energy has been used but not as much as in the countries with more appropriate climate. One of the most modern energy sources nowadays is the sun energy, to put it more clearly, the energy gained by the fotovoltaic method. The least used, but still possible way to gain energy is the geothermal energy that has been used especially in Island. In the Czech Republic, the most promising way to gain energy is the biomass that can be effectively burnt in the carrent power plants. Two main approaches to biomass usage developing in the Czech Republic have been the use of wood or the use of remnants of wood, be it wood chips, shavings, pellets etc. As I have already uttered earlier, the second source of biomass is the waste material from earlier human activites. Waste materials from households, agriculture and husbandry, muck or slurry can be made use of. This kind of biomass is burnt in the fermentation gas stations that are usually part of waste-treatment plants.
