The aim of diploma thesis is to analyse the overall technical base and to monitor logistic processes which are from the very beginning associated with radioactive waste and spent nuclear fuel. The main emphasis is put on spent nuclear fuel from nuclear power plants. The current situation in this area is illustrated by an example of the Czech Republic and Sweden. The comparison of Czech and Swedish system leads to demonstration of strengths and weaknesses of the used methods.

The thesis deals with the relationship between ecology and law in nuclear energy and the possible impact on the environment. The first part briefly summarizes the most important historical approaches to ecology and describes environmental law in the Czech Republic and the EU. The next section is focused on law in the area of construction and operation of nuclear power plants in the Czech Republic and the EU. The fourth chapter deals with operation of nuclear power plant Temelín and assessment the legislation. The fifth chapter is dedicated to various forms of longstanding conflict between the Czech Republic and Austria.

Nuclear law in the Czech Republic Abstract Nuclear law can be defined as a set of legal rules designed to regulate legal or natural persons engaged in activities related to fissile materials, ionizing radiation, and radiation from natural sources of radiation, with the aim of ensuring the protection of persons, property, and the environment. The topic of the thesis Nuclear law in the Czech Republic is the legal regulation of peaceful use of nuclear energy and ionizing radiation in the context of Czech legislation within the framework of public law, including its links and connections to the legal regulation of this issue at the international (European, global) level. After a brief introduction of nuclear law and its basic terminology, the thesis presents in a comprehensive summary the legal regulation at the international, European and national level, together with the legal principles that are manifested within the legal norms of nuclear law. Within the framework of the Czech legal framework, the main focus is on Act No. 263/2016 Coll., the Atomic Act, and its relation to individual areas of nuclear law. In terms of institutional arrangements for the administration of the use of nuclear energy in the Czech Republic, the institutions with significant competencies within the framework of nuclear law are...

This work deals with the connection between the luminance of Cherenkov radiation in a nuclear reactor and his power. Cherenkov radiation arises when charged particle passing through the medium if their speed is higher than the phase velocity of light in that medium. In water moderated reactors, it is caused by secondary electrons produced by absorption of gamma rays. The measurement is done using the camera and software for photometric luminance measurements. Furthermore, there is mentioned the use of Cerenkov radiation detection to measure burnout of spent nuclear fuel. There are examples of usage of Cherenkov radiation detection to measure of nuclear reactors power, including an analysis of the measured results on research nuclear reactor VR -1. The measured results show increasing intensity of Cherenkov radiation with increasing reactor power, but residual detection response caused by delayed gamma radiation was observed after the rapid decrease of the reactor power. Possible use of detection luminance of Cherenkov radiation is in monitoring unforeseen increase in reactor power or in the control of used fuel.

This work deals with questions of spent fuel storage casks thermal and physical properties investigation. Foundations of mathematics which are necessary for describing field of temperature are included. The work itself contains calculation methods which are split into two parts. The first one deals with simplified analytic solution and the second part solves the whole problem by the numerical computation.

Tubulin is the basic building block of microtubules which ensure intracellular transport, morphological changes, the connection of proteins of metabolic pathways, the segregation of chromosomes during mitosis and many other essential processes in plant cells. The localization of tubulin regarding nucleus is strictly controlled and during the interphase, tubulin is usually not present in the nucleus. As we previously showed, one of the exceptions of the presence of tubulin in the nucleus is the cold stress condition. Also, we discovered several plant-specific nuclear export sequences (NES) in tubulin molecules: one in α-tubulin and two in β-tubulin. In this work I found that double mutation of both functional β-tubulin NESes cause slight accumulation of the protein in the nuclei. However, the phenotype of the transgenic plants expressing β-tubulin with mutations is probably not affected by the presence of the mutated protein. The effect of the expression of the mutated β-tubulins was observed in Nicotiana tabacum BY-2 cells as well. The expression of β-tubulin carrying a single NES3 mutation or double mutation of both NESes bring changes of the division activity of the cells, while the NES2 mutation does not have any effect. Furthermore, it was discovered that the 0řC cold tr eatment does not cause...

The safety and performance of nuclear plant relies, among others, on the quality of nuclear fuel. The quality fulfilling designed criteria of the fuel in use is inspected and reported on periodically. Visual inspection focuses on the condition of the fuel based on its visual properties. During the inspection, the fuel is being recorded and analysed by the inspector. The current state of the fuel assemblies is compared to the historical statistics which helps do decide whether this particular assembly remains or gets replaced. This thesis describe a project initiated by Centrum Výzkumu Řež focusing on digital image processing methods application to visual inspection process. The result of the project is a tool that accelerates the process of report making. Firstly, it transforms the inspection video into one image overview and highlight a significant part (more than 95%) of possible defects to the inspector. 1

The development of nuclear weapons and their proliferation: A comparison of Iran and North Korea Master Thesis Author: Martin Marek Supervisor: PhDr. Vít Střítecký, M.Phil., Ph.D. Year: 2016 Abstract The text deals with nuclear proliferation in the cases of Iran and North Korea. The motives of nuclear ambitions are examined using models of Scott D. Sagan and other selected theoretical concepts. Gradual analysis of exposed states in the perspective of historical development, national security, domestic politics and norms forms the basis for understanding the perception of nuclear weapons by these states and approach to them as to a mean to accomplish certain objectives. Subsequent comparison reveals both similarities and difference between examined states in the perspective of motives of nuclear proliferation and shows explanatory potential of each model, which is various, in given cases. The effort of ensuring national security seems to be the strongest motive in both examined cases. It is followed by domestic influences, whereas norms stand rather for additional factor. Nevertheless, variety in explanatory power of the models is apparent in the cases of Iran and North Korea, notably in relation with their limitations. Other factors, such as regime type or parallel development of other type of weapons of...

The aim of this work is to determine the influence of nuclear weapons possession in 1) Russia's foreign policy in the Ukraine crisis, 2) relations between NATO and Russia. For this purpose the work monitors the development of NATO - Russia relations from the Budapest memorandum until present. The work also creates typology of russian signalling activities based on the theoretical basis of the nuclear deterrence conceptions and especially on the models of crisis signalling, which is closely linked to these conceptions. After monitoring these activities the work concludes that Russia is indeed using threats of nuclear weapons employment in the framework of it's attitude towards Ukraine crisis and also the intensity of signalling shows similar development as the relations with NATO.
