Approach to the nuclaer safety of the 3rd generation nuclear reactors
Pavlíček, Michal ; Kolář, Jaroslav (referee) ; Kolář, Jaroslav (referee) ; Matal, Oldřich (advisor)
The main target of the master´s thesis is reviewing the generation III nuclear reactors in term of the nuclear safety. At first we have to learn some theory of the nuclear safety in order to understand safety systems of the generation III nuclear reactors. Therefore the thesis is divided into two parts. Legislative and technical approaches to nuclear safety are mentioned in the first part. Regulatory bodies, whose task is to supervise nuclear safety in the nuclear power plants, belongs to the legislative approaches. There are defined terms such as defence in depth, redundancy, diversity, etc. There are mentioned methods to assessing nuclear safety – deterministic and probabilistic methods, especially probabilistic methods, for which a simple example is provided. There are also mentioned active and passive safety systems and their significance for nuclear safety and inherent safety too. There is an example of the function of the active and passive safety systems of the EDU nuclear power plant in conclusion of this issue. The second part deals with description of the selected nuclear reactors in context of the construction of the new units of nuclear power plant in Temelín. The nuclear reactors from companies, which applied for the public tender opened by ČEZ, a. s., for the construction of the ETE 3+4. Thus, the nuclear reactor MIR-1200 by ATOMSTROYEXPORT (Russian Federation), the nuclear reactor AP1000 by WESTINGHOUSE (USA) and the nuclear reactor EPR by AREVA (France) are taken into account . Comparison of the generation II and these generation III+ nuclear reactors necessarily belongs to this master´s thesis. These the generation III+ nuclear reactors are compared with the nuclear reactor VVER 440 (EDU) and in particular with the nuclear reactor VVER 1000, which is operated in the nuclear power plant Temelín. The final chapter contains generally appraisal of the whole problem.

Automation of layoutplanning
Pavlíček, Michal ; Zemčík, Oskar (referee) ; Hlavenka, Bohumil (advisor)
This thesis deal with suggestion of program, which channelize technologist-planner whole tasks which are unit with projection. Deal with capacitive calculation methods and technology projection methods. This methods were implementing in program Excel and AutoCAD. It was reaching configurational guide in html format, which unit whole section of program.

Proposal for heating of family house
Pavlíček, Michal ; Špiláček, Michal (referee) ; Hrnčířová, Michaela (advisor)
Family houses heating, depending on economic factors, is currently highly discussed topic. My work evaluates the possibility of heating such houses. The technical possibilities of model building and design of optimal heating sources are taken into account. The link of investment requirements and their return is also observed.

Necessity of quality management
Pavlíček, Michal ; Kružík, Michal (referee) ; Fiala, Alois (advisor)
Task of the thesis is to develop a literature search on the topic: „Necessity of quality management“. The paper defines the concept of quality and quality control. These are basic concepts for this extensive and still very dynamically developing field. I tried to create objektive look on these questions and in the end think about necessity or uselessness of quality management systems.

Heat exchangers for air-conditioning
Pavlíček, Michal ; Jaroš, Michal (referee) ; Hejčík, Jiří (advisor)
The thesis is divided into 2 parts. The first part deals with classification and characterization of heat exchangers. The sizing process of plate heat exchangers is described and demonstrated in the second part. Obtained results are compared with real plate heat exchanger produced by Güntner Company.

Environmental conditions during the carp pond harvesting
PAVLÍČEK, Michal
Pond harvesting is an integral part of fish farming procedures in pond culture and overall fish production. This study was aimed at the evaluation of environmental conditions during pond harvesting, based on the comparison of values monitored in the trawl-net with fish located in a harvesting pit and outside it. The monitored parametres comprised the oxygen content and saturation, temperature, pH, conductivity and turbidity. The monitoring was performed on three autumn harvests (Potěšil, Rod, Jaroslavický dolní) and two spring harvests (Vrbenský přední and Vrbenský nový), always during the fish removal from the net (seine). The monitored determinants were recorded in 30-min intervals inside the net with fish and outside it in 15m distance. During the statistical comparision of the oxygen content and saturation in the net and outside it with the count on fish biomass was statistically signifiant differences in the four of twelve raids evaluated, which means keeping fishes in the net during the yielding was adequately treated by installation of fresh water jet.When the fresh water jet had been stopped worsen of the conditions in the fish net and even in the harvesting pit appeared.

Effect of electrofishing on macrozoobenthos
PAVLÍČEK, Michal
Experiment has been addicted for observing effect of electrofishing on macrozoobenthos including mechanical stimulus (passing of trawling squad). Reaction on electrofishing and fading has been rebound by drift increment. Sample taking had been done by use of Surber and drift nets. Evaluation has been made both quantitative (standing crop in drift in particular methods), and qualitative (substitution of taxons in particular methods).
