Nuclear power plant accidents and their impacts
BOROVKA, Petr
This bachelor thesis deals with the issue of nuclear power plant accidents. First the basic terms for nuclear energy are explained. Then the reactor and the types of reactors used are described. Furthermore safety systems for nuclear energy are analyzed and examples of systems used are given. The Temelín nuclear power plant is described, because of comparison that comes afterwards. After that the topic moves on to the description of three serious accidents of nuclear plants. Specifically accidents at the Chernobyl nuclear power plant, the Fukushima nuclear power plant and the Three Mile Island nuclear power plant. Furthermore in the following chapters a comparison was made of the individual described accidents with the Temelín nuclear power plant. For the Chernobyl accident the comparison consists of comparing the biological shield with containment, xenon poi-soning and positive cavity coefficient, control rods, backup types of power supply, and finally the explosion during the accident is analyzed. For comparison with the Fukushi-ma accident, the risk of natural disasters in the area where the Temelín nuclear power plant is located is pointed out also an analysis of rivers near the nuclear power plant was made. With the Fukushima accident, the differences in containment structures and the risks associated with the accident are described. Furthermore, the accident of Three Mile Island was compared with the accident at the Rovno nuclear power plant, as it was the same type of accident with different results. Then a comparison was made in measuring the water level in the reactor and the procedure for measuring the water level for the VVER-1000/V320 type reactor was described.

Emergency and current exposure situation in residential areas of Fukushima prefecture - aspects of communication of low dose risks
ŠÁROVÁ, Romana
The diploma thesis examines the post-accident and current exposure situations in residential areas of the Fukushima prefecture and discusses certain aspects on communication concerning the risks of low doses. The evaluation was based on research and collection of information and data from printed and electronic resources. The results show the sequence of steps carried out by the Fukushima prefecture and IAEA and the degree to which they were successful. The aim of the diploma thesis is to offer a clear comparison of the monitoring of the post-accident situation in specific areas of the Fukushima prefecture and the situation achieved after a comprehensive decontamination and remediation of the environment. We compared the measured values of the current radiation situation at the Fukushima prefecture with values in the Czech Republic, available thanks to the MONRAS application. The thesis also examines how the authorities communicated with the people of Fukushima before the evacuation and in the period after the evacuation when the habitable part was decontaminated and the government sought (and still seeks) to return people to these areas. I also explored the approach to the optimisation of radiation protection in Fukushima, how this principle can be interpreted in the Czech Republic and how to contribute to sufficient awareness of the population in terms of a general understanding of the limits and optimisation of radiation protection in case of a nuclear accident. For this purpose, an informational brochure was created using the Canva Pro online tool. This brochure represents the practical output of the diploma thesis. The decontamination efforts can be considered successful, given that the measured content of caesium in the environment has been radically lowered; one negative consequence was the creation of a large amount of radioactive waste. The air dose rate is comparable to general global background radiation. The residents therefore don't need to be afraid to return to their homes.

Nuclear accidents and subsequent measures to protect the population
SVITÁK, Daniel
This bachelor thesis deals with the protection of the population and subsequent measures in the event of a radiation emergency. When comparing the two largest nuclear accidents (Chernobyl and Fukushima), a great similarity was found not only in the implementation of safeguard measures, but also in the errors made by the responsible authorities. By comparing these events, we could answer the question of how the approach to protecting the population differed in the bipolar division of the world from the perspective of the "Eastern", which is represented by the former USSR and the view of the "Western" represented by Japan. With the resulting analysis, we confirmed that in both the USSR and Japan, this approach differed only in the source of the likely risk, which was given greater attention than the other risks. In case of comparison of the measures of protection of the population of the Czech Republic, which are mentioned in the emergency plans, with those introduced in the world in the case of The RMU, we concluded that the measures of the Czech Republic are on the same level and can be considered as a world standard. To support the resulting claims, the measures introduced at the Fukushima RMU are compared with those during the 2015 Zone Temelín emergency exercise. An integral part is the evaluation of the level of information of the Czech population in the field of protection of the population. An analysis of the results of the supplementary questionnaire survey confirmed the claim of low level of information of the inhabitants of the Czech Republic. Therefore, the work will also focus on the need to raise public awareness in the field of population protection and propose measures to raise the level of information to the required level.

Behaviour of radioactive substances in the Vltava and Elbe Rivers during nuclear accident
Juranová, Eva ; Hanslík, Eduard (advisor) ; Matějíček, Luboš (referee) ; Světlík, Ivo (referee)
Behaviour of radioactive substances in the Vltava and Elbe Rivers during nuclear accident Ing. Eva Juranová Supervisor: Ing. Eduard Hanslík, CSc. Abstract This work is focused in the research of the behaviour of radioactive substances released into the hydrosphere of the Vltava River and the subsequent Elbe stretch during a severe accident at the Temelín Nuclear Power Plant. The background values of anthropogenic radionuclides in surface water, residual contamination after the Chernobyl accident and after atmospheric tests of nuclear weapons, were evaluated using two methods and these methods were compared. The migration of the accidental radioactive contaminants in the watercourse would be mainly influenced by their ability to sorb onto the solid phase in the hydrosphere. Therefore, the sorption of particular anthropogenic radionuclides onto bottom sediments and solids suspended in the water column was monitored and evaluated at several sites along the Vltava and the Elbe Rivers. Furthermore, the possibility of using tritium, which is discharged during normal operation of the Temelín power plant, as tracers for the purposes of modelling the migration of pollution, was assessed.

The awareness of the Vysočina region population about the nuclear disaster Černobyl
ROYIK, Tetyana
The diploma thesis deals with the awareness of population of the Vysočina Region of the Chernobyl nuclear accident. The aim of this thesis is to find out the level of knowledge of the population about this accident and then to compare the knowledge of the population aged 18-44 and over 45 years. Two hypotheses were set in the thesis, H1: More than 2/3 of all respondents in the Vysočina Region will have more than 60 % of correct answers in a questionnaire concerning the knowledge of the Chernobyl nuclear accident, and H2: Respondents over 45 will have significantly higher knowledge of the Chernobyl nuclear accident than inhabitants under 45 years of age. In order to achieve the defined objectives and to verify the hypotheses, a questionnaire was prepared, a questionnaire survey was carried out and then the results were evaluated using the methods of descriptive and mathematical statistics. The questionnaire consisted of 15 questions. The research group consisted of 100 inhabitants aged 18-44 and 100 inhabitants aged over 45. The results of the questionnaire survey show that the overall success-rate of the answered questions was 66 %. Residents aged 18-44 responded correctly in a total of 61 % and residents over 45 in 71 %. The stated aims of the thesis were achieved and both hypotheses were confirmed. The benefit of the thesis is mainly the acquired picture of the state of awareness of the population of the Chernobyl nuclear accident in the Vysočina Region. The obtained results of the diploma thesis can be used, for example, by crisis management authorities related to the issue of nuclear energy or protection against ionizing radiation, both in connection with preparation for these situations and with a focus on preventive educational activities.

The knowledge of the population of the Czech Republic about the radiation risks resulting from accident at the Chernobyl Nuclear Power Plant.
JAROŠ, Luboš
The Chernobyl disaster is still considered to be one of the biggest catastrophic accidents in the history of nuclear energetics. After the explosion of the nuclear reactor, abundance of radioactive substance escaped to the atmosphere and in the shape of the radioactive cloud affected even the area of the former Czechoslovak Socialist Republic. Political parties and state authorities reacted on this situation by setting up the state committee, which under political pressure intentionally concealed the information about the risks and consequences of the disaster for the Czechoslovak population. The collapse of the regime not only revealed the crisis of the mistrust to the official sources of information, but also improved the effort of getting information from unofficial and, according to regime, illegal sources. The Chernobyl disaster also caused the mistrust to nuclear energetics. Therefore construction and initiation of the Temelín nuclear power station elicited the interest to the information about The Chernobyl disaster. I have decided to authenticate in my thesis, how well the residents of the Czech Republic are familiar with the Chernobyl disaster and how objective their knowledge about the radiological risks arising from the Chernobyl disaster at present are. I found out the state of the foreknowledge of the residents of the Czech Republic about the radiological risks arising from the Chernobyl disaster by means of questionnaires, where 200 respondents were interviewed. For more detailed research, I divided the residents of the Czech Republic into two groups. The first one consisted of the inhabitants that live in the zone of the disaster preparedness of the Temelín nuclear power station and comprise one half of respondents. The second group consisted of the inhabitants that live of the zone of the disaster preparedness. I drew up questions in the questionnaire in order to include the given problems completely ? from the knowledge about the risks arising from the disaster and emission of the radioactive substances to their consequences for human?s health and the way of reduction their impacts on the population of the Czech Republic. I evaluated the answers from the respondents to the single answers and drew up the tables. I accomplished them by the percentage evaluation of the right and wrong answers, computation of total mean of the achieved points and the total percentage success rate. The evaluation of the knowledge of the respondents of the Czech Republic was accomplished on the basis of the value of total mean of the achieved points and percentage success rate. I did a statistical evaluation by testing normality using ?2 Pearson's chi-squared test. The mutual comparison of the knowledge I did by testing by means of the two-sample t-test on the basis of the guess of the empirical parameters from each group. On the basis of this evaluation of the results of the questionnaire I can declare that the knowledge of the residents of the Czech Republic about the radiological risks arising from the Chernobyl disaster are at a very good level. The results also proved that inhabitants of the zone of the disaster preparedness of the Temelín nuclear power station have greater knowledge about the radiological risks arising from the Chernobyl disaster than the rest of the Czech Republic. It can be observed in the conclusion that all predetermined aims were successfully achieved and the results of the questionnaire also proved the assigned hypothesis.

Duties and arrangements of crisis staff of the municipallity with efussed agency close to outflow of radioactive matters
NÁZROVÁ, Lucie
The issue concerning endangering by radioactive substances has not been published frequently. Yet it can represent a very high risk with irreversible consequences for both man and the environ{$\neg$}ment he lives in. Even though there are regular checks of the sources of radioactive emission and the issue is being monitored in fallout plans, one cannot wholly exclude the possibility of endangering inhabitants by radioactive substances. For example the failures of technologies, a man{\crq}s irresponsibility, criminal acts, especially terrorism and also the exploitation of nuclear weapons to military or political goals cannot be omitted. Consequences of extraordinary events and critical situations in case of radioactive substances threat can be catastrophic.
