This thesis is focused on the study of sorption of radionuclide 85 Sr in soil collected in the area of a nuclear power plant Temelín. A single-batch method experiment was used when a solution of radionuclide 85 Sr of known activity was added to the soil. The experiments focussed on the influence of pH with the size of the sorption and the influence of the time of the contact of the solution with the sorption. During the experiment with the value of pH closest to the pH of underground water from the nuclear power plant Temelín, the sorption of soil was somewhere between 31 to 44 %. When the time influence on the sorption was examined, radionuclide 85 Sr was sorbed very quickly. For the comparison of the sorption size in connection with the time, for which it was chosen 120 minutes, the sorption was almost constant, reaching 40 to 48 %. Key words Radioactivity, radionuclide 85 Sr, sorption, nuclear power plant Temelín

At the beginning of the millenium, has the longtime and quite emotional dispute between Czech Republic and Austria concerning the nuclear power station Temelín reached its peak. In my thesis, I am focusing on Austrian antinuclear policy, its genesis and aspects, that aroused it based on the attempt to stop the nuclear power station Temelín from activation. Initially I am observing the historical experience of Austrians, which influenced their attitude toward nuclear power. Antinuclear consensus has gradually developed into a modern national ideology and the most significant milestone on the journey to denucleated state, the referendum of nuclear power in Zwentendorf, has become indulged myth of modern Austrian history. Controversies around nuclear power station Temelin has influenced aspects, that define Austrian political and social live, and these take a large share in relations between the Czech Republic and Austria becoming acute, especially in years 2000-2002. Those aspects, that I introduce as dimensions in my thesis, are following: federal structure of Austrian polical system and frequent independent actions of the heads of the executives of Austrain states with their own interests; party-political dimension, that means the presence of right-winged populist FPÖ in the government from 2000;...

In this thesis I target the assesment of a volume activity of gamma ray nuclides in the environment and the examination of the operation the Nuclear Power Station (NPS) Temelín in term of emitting the gamma ray nuclides and their environmental impact. There were collected data of several sorts of environmental samples for statistical analysis. The activity of gamma ray nuclides released by nuclear power plants to the environment after its initiation was compared to the activity of gamma ray nuclides contained it the environment before the initiation of the NPS. It was chosen five exemplary samples - , aerosoles, sediments, milk, soil and surface moisture, which have been scanning in years 1995 and 2005. In these samples, that have sufficient amount of data (sorts of milk, aerosoles and surface moisture) so the statistical analysis was relevant, it was proved, by the non-parametrical Mann-Whitney statistical testing, that there were no statistical difference between the data before and after the initiation of the NPS. The environmental impact wasn´t demonstrated. In these samples, that haven´t sufficient amount of data (sediments and soil), they were also tested (parametrical t. test) and it was proved that there were no statistical difference between the data before and after the initiation of the NPS. Because of very low quality of the testing, we have to use the box plot to ascertain the influence of NPS. In these plots the environmental impact wasn´t demonstrated as well.

This work deals with occupational professional exposures at Temelín Nuclear Power Plant. The introductory part is devoted to types of ionising radiation participating on radiation load of workers, values and units and to the essential legislation requests associated with individual monitoring. In the following part characteristics of methods used to measure individual doses of external exposures like film dosimetry, thermoluminescent do-simetry, radio-photoluminescent dosimetry and electronic dosimetry are described. For assessment of the committed effective dose from the internal exposures in vivo moni-toring or indirect measuring were used. The possibilities of the occupational dose optimisation were discussed Results of individual monitoring in 2005 and 2006 and layout of monitoring program are presented in this work. The new monitoring program is based on the active personal dosimeters (EPDs) rather than on the passive ones and covers the period of transformation between them. With respect to the passive dosimeters, EPDs offer some advantages which on one hand contribute to a better exposure control and on the other hand foster the development of a sound culture in radiation protection due to direct feedback of dose information.

The thesis Temelín Nuclear Power Station and Czech-Austrian Relations deals with the Temelín Nuclear Power Station and nuclear industry and its influence to the Czech-Austrian relations. The study aims to analyse the relations between the Czech Republic and Austria in the context of the power station from 1993 to 2013. Initially, the thesis introduces the theory of constructivism in the International Relations. Afterwards, it aims to explain the differences between the relations to the nuclear energy by Czechs and by Austrians on the basis of the theory of constructivism. Moreover, the thesis introduces the historical, legal and technical circumstances of the Czech-Austrian dispute. The main objective of the thesis is to ascertain, what effect on the Czech-Austrian relations have mediums, which publish articles about the Temelín Nuclear Power Station. There are four Czech relevant newspapers (Blesk, MF DNES, Právo and Lidové noviny) and four Austrian relevant newspapers (Kronen Zeitung, Kurier, Der Standard and Die Presse) inquired in the thesis. Particular articles are evaluated by the stances on the issue (pronuclear, antinuclear or impartial). The thesis identifies, which of the mediums have impact on deterioration/improvement of the Czech-Austrian relations. The study also deals with the process of...

The main goal of this Thesis was to measure tritium activity in the Vltava River and in the vicinity of Temelín Nuclear Power Plant (hereinafter referred to as JETE) with the following objectives: Possibility to use the outlet of waste water damping unit (hereinafter referred to as VTOOV) as a control alerting system for nonstandard events in JETE, furthermore, monitoring of possible correlations between volume activity of tritium measured in VTOOV and activity above the limit value of the first quality class in selected sections of the Vltava River as well as comparison of the measured values with the results of other authors, and, finally, assessment of the relevance of the water quality estimated by the volume activity of tritium to the water quality according to other ingredients, i.e., stable isotopes of some metals and risk elements as well as general physical and chemical indicators. Theoretical part of the Thesis deals with radioactivity in general, activity of tritium, with regard to operation of nuclear plants, over the world and, especially, in the Czech Republic. The actual work consisted of collection of samples at predetermined places, preparation of these samples for measurement and measurement of tritium activity using scintillation spectrometer with liquid scintillator. Furthermore, basic chemical and physical properties of water, concentration of selected elements and also some anions were determined. The collected data were used for classification of waters from individual collection places into quality classes according to ČSN 75 7221. In all analyzed cases no activities were found which exceeded the limit values of liquid outlets from Temelín Nuclear Power Plant, given by regulations issued on waters by the District Health Office in Ceske Budejovice according to §8 of Act No. 138/73 Coll., in compliance with SÚJB requirements. This Thesis could be beneficial for possible utilization of VTOOV as a control alerting system for nonstandard events in JETE and also for assessment of impact of wastewaters from JETE on waters of the Vltava River.

Nuclear fuel failures during the reactor operation happen quite often in the world. The theoretical part of this thesis is dedicated to the most common causes of nuclear fuel failures. It describes failure mechanism and corrective actions. The unfavorable trends in nuclear fuel behavior are prevented by suitable method of nuclear fuel monitoring. Some of them may affect the safety of the power plant. For example, the fuel assembly bow affects the function of rod cluster control assembly. Another part, which describes inspection methods, is devoted to inspection and repair of nuclear fuel. The thesis concentrates on the Temelin NPP, where there was implemented post-irradiation inspection program for checking compatibility between Westinghouse's fuel assemblies and water chemistry of reactor VVER. This program continues even after the change of nuclear fuel supplier. Practical part of this thesis is dedicated to proposal of a new method of fuel assembly bow measurement for Temelin NPP based on ultrasound. This proposal is supported by measurement on the experimental device for detection of spacer grid position developed by Research Centre Rez.

This diploma thesis is based on an analysis of knowledge of inhabitants within the emergency planning zone of operations, security and behaviour in case of an accident in the Temelín Nuclear Power Plant (TNPP). Operation a nuclear equipment in connected with certain risks which can´t be utterly eliminated. From this reason, security precautions are made, which are based on an accident preparedness, or on emergency plans. Emergency planning serves to a preparedness for non-standard or emergency situations for an area which is called an emergency planning zone. The emergency preparedness, not only within this zone, has a key role for a successful performance of inhabitants´ protection in case of an emergency event. The concept of emergency preparedness includes both the emergency planning and inhabitants´ awareness and knowledge of operations, risks and following precautions in case of an accident in TNPP. The aim of this diploma thesis is to inquire about "What is knowledge of inhabitants within an emergency planning zone of the Temelín Nuclear Power Plant operations?" The theoretical part is based on consulting the employees of ČEZ Ltd. Who work in the Temelín Nuclear Power Plant as well as on a study of professional literature, articles and related legislation. The practical part is based on a questionnaire survey and it is divided into three parts: operations, risks, security, knowledge and behaviour during an accident. The results revealed some margins in respondents´ knowledge concerning issues of operations as well as knowledge and behaviour during an accident. A positive evaluation concerns respondents´ knowledge of used nuclear fuel, the meaning of containment building and the procedures in case of evacuation. On the other hand, the respondents showed insufficient knowledge of the function of a reactor, what barriers are between the active zone and environment and when to use iodine prophylaxis. I consider the present status of inhabitants´ knowledge of TNPP operations insufficient and I propose some improvements. It is important to focus on inhabitants older than 50 years, whose lack of knowledge is even alarming.
