	Analysis of the possibility to perform evacuation of inhabitants at the pre-leakage phase of radiation accident in nuclear power plant conditions MAKRLÍK, Jaroslav Nuclear facility accidents involving leaks of radioactive substances into the environment might have serious radiobiological impacts on inhabitants in some cases and would require immediate or subsequent protective measures from iodine prophylaxis and hiding to evacuation or permanent resettlement. The first part of the thesis describes the conditions of nuclear facility operation, technology of the Temelin nuclear power plant, including description of technology and function of emergency systems and the basic principles of security, and environment protection. It also describes the principles and aims of nuclear safety, radiation protection and accident preparedness. A more detailed description of accident preparedness at the Temelin power plant including links to the External Emergency Plan and announcement of safety measures for inhabitants follows. The aim of the thesis is to evaluate the decision making process on announcement of evacuation in the pre-leak phase of radiation accident from the point of view of the Temelin nuclear plant operator?s possibilities. The part Methodology includes a description of RTARC software for evaluation of radiological impacts of radioactive substance leakage into the environment of the Temelin nuclear plant in case of radiation accident. The set of source members (event scenarios) used for the calculation is also described there. The chapter Results presents and assesses the RTARC calculations. We may say upon analyses of the results that application of the decision making support programme is beneficial and is practically able to help with efficient protection of citizens in the final effect. For a part of the considered source members evacuation on pre-leak phase cannot be recommended with regard to the quick progress and leakage of radioactive substances into the environment.

	Monitoring of the carbon-14 in the gaseous releases from the Temelín NPP and its environmental distribution VALÁŠEK, Michal This work deals with monitoring of the radiocarbon in the gaseous effluents from the Temelín nuclear power plant and its distribution in the environment. The reader should gain a comprehensive image about level of radiocarbon monitoring in ventilation systems in the Temelín nuclear power plant and in the surrounding environment. The work is divided into several parts. Some basic information of physics, chemistry and radiobiology relating to radiocarbon are given in the first part. The origin of radiocarbon in VVER reactor, its pathway to gaseous releases and then to carbon cycle in the environment are described there too. This introductory part continues with description of monitoring methods used in ventilation systems of the Temelín nuclear power plant and in the surrounding environment. Summary of Czech Republic legislation related to radiation protection is stated. The aim of the work and hypothesis are set in the second part. In the third part there are methods used to fulfil the aim of the work. The results in the form of tables and graphs are in the fourth part. In the following part there is a discussion of summarized data and results. Developed findings are summarized in the last part of this work. Detailed record
	Monitoring of the occupational radiation exposure at Temelín nuclear power plant CUPALOVÁ, Klára 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.
