Turkey is an energy dependent country with more than 75 percent of its energy being imported from foreign countries. The level of dependency is increasing every year because of the rising energy needs and the lack of national production. Among all forms of energy, increase in demand for electricity is the highest. At a time that some countries are announcing their decision to phase out nuclear power plants (NPPs) in favor of renewable energy sources, Turkey appears to be determined to proceed with its decision to acquire nuclear technology despite safety concerns. A country that has seen domestic opposition towards nuclear energy has already made significant progress towards acquiring one. This article uses a policy analysis framework to assess the value of nuclear energy in Turkey from an energy security perspective. It argues that energy security for Turkey can be dealt with thoroughly when the problem of resource diversification is addressed from a comprehensive perspective. Pros and cons of having NPPs in Turkey will be analyzed through energy security parameters vis-a-vis the urgent need for resource diversification.

The paper defines the directions of improving turbogenerators as the basis for ensuring the energy independence of Ukraine. The analysis of the state, problems and prospects for the development of modern electric power industry. Goal of the work is to identify promising directions for sustainable development of the national electric power industry in order to ensure energy security of Ukraine, to conduct a comparative analysis of electricity sources, to confirm the need to improve the main sources – turbogenerators. Methodology. During the research, an analytical analysis of the electricity sources, which are installed at power plants in Ukraine and the world, was carried out, taking into account the growth of the planet's population and its energy activity. Cyclic theory was chosen as the theoretical basis for forecasting. On the basis of this theory, global development trends, advantages and disadvantages of currently used sources of electricity - thermal (including nuclear) power plants and stations that operate from renewable energy sources - have been established. A review of literary sources on the methods of the energy sector forecasting the development, including the development of the energy sector in Ukraine, has been carried out. Originality. It has been established that due to the active growth of the planet's population, with the increase in its energy activity, obtaining electricity from renewable energy sources is not enough, that for the next 20-30 years nuclear power plants will be the main sources of electricity. The internal and external threats to the energy security of Ukraine, directions of development of turbogenerator construction, ways to improve turbogenerators, to increase their energy efficiency, power per unit of performance, to increase the readiness and maneuverability factors, and overload capacity have been identified. Practical significance. The need to continue the modernization and improvement of the turbogenerators of nuclear power plant units, as the main sources of electricity, has been proved. The directions of their improvement are established: increasing the power in the established sizes, making changes to the design of the turbogenerators inactive elements, replacing the cooling agent to keep Ukrainian turbogenerators at the world level, improving auxiliary systems, improving and increasing the reliability of the excitation system, introduction of automatic systems for monitoring the state turbogenerators. Possible limits of use, advantages, disadvantages and problems of using renewable energy sources for Ukraine have been established.

AbstractIn the January 2006 State of the Union address, President Bush announced a new Advanced Energy Initiative, a significant part of which is the Global Nuclear Energy Initiative. Its details were described on February 6, 2006 by the U.S. Secretary of Energy. In summary, it has three parts: (1) a program to expand nuclear energy use domestically and in foreign countries to support economic growth while reducing the release of greenhouse gases such as carbon dioxide. (2) an expansion of the U.S. nuclear infrastructure that will lead to the recycling of spent fuel and a closed fuel cycle and, through transmutation, a reduction in the quantity and radiotoxicity of nuclear waste and its proliferation concerns, and (3) a partnership with other fuel cycle nations to support nuclear power in additional nations by providing small nuclear power plants and leased fuel with the provision that the resulting spent fuel would be returned by the lessee to the lessor. The final part would have the effect of stabilizing the number of fuel cycle countries with attendant non-proliferation value. Details will be given later in the paper.

Рассмотрено состояние и перспективы развития атомной энергетики в связи с сейсмической и другими природнотехногенными опасностями. Анализирован опыт эксплуатации АЭС, статистика аварий на АЭС, их причины. В связи с авариями на ряде АЭС и глобальной сменой приоритетов энергетической политики в сторону возобновляемых источников энергии (ветра, солнца, гейзеров и т.п.) многие из технически развитых стран (США, Япония, Германия) заявляют о снижении роли атомной энергетики в собственных энергетических планах. Угроза опасности объединяет усилия таких стран как США, Франция, Россия, Япония, Южная Корея, Канада и Китай в сотрудничестве в области совершенствования технологий, усиления ядерной безопасности и развития ядерной инфраструктуры в странахновичках. Наиболее опасными признаны АЭС Азии, где отмечается повышенная сейсмичность. Благодаря усилиям по повышению безопасности АЭС, сделан вывод о снижении сейсмической опасности в связи с глубокой автоматизацией и передачей основных управляющих функций АЭС программному комплексу, совершенствованием алгоритмов принятия решений в случае землетрясения и других чрезвычайных ситуаций. Одна из главных целей глубоко эшелонированной защиты состоит в блокировании опасностей человеческих ошибок и сочетания отказов оборудования и ошибок операторов и распорядителей. Системы безопасности должны включаться автоматически и на некоторое время блокировать действия оператора АЭС. Эффективной защитой энергоблоков, построенных в последние десятилетия, являются герметичные оболочки (контейменты) и размещение над реактором емкости с большим количеством раствора бора, который выливается на реактор при аварии и нейтрализует радиоактивность в случае ее появления. Более детальный анализ сейсмотектонической ситуации площадок действующих АЭС мира привел к необходимости повышения ускорения безопасного останова в ряде АЭС. При проектировании АЭС недостаточно учитывать магнитуду и интенсивность предполагаемых землетрясений, для инженерных расчетов необходимо использовать конкретные параметры колебаний. Среди них важнейшее место занимает ускорение грунта, по которому можно с максимальной уверенностью судить о потенциальных нагрузках на сооружения и оборудование в зоне землетрясения. Приведена модернизированная система сейсмической защиты (ССЗ1М) энергоблоков отличающаяся надёжностью, отсутствием ложных срабатываний, стабильностью параметров во времени, защитой от внешних несанкционированных воздействий. The state and prospects of the development of nuclear energy in connection with seismic and other natural and technological hazards are considered in the article. The experience of operating nuclear power plants, statistics on accidents at nuclear power plants, and their causes are analyzed. Due to accidents at several nuclear power plants and a global change in energy policy priorities towards renewable energy sources (wind, solar, geysers, etc.), many of the technically developed countries (USA, Japan, Germany) declare a reduction in the role of nuclear energy in their energy plans. The threat of danger unites the efforts of countries such as the USA, France, Russia, Japan, South Korea, Canada and China in cooperation in the field of improving technologies, enhancing nuclear safety and developing nuclear infrastructure in newcomer countries. The most dangerous nuclear plants are located in Asia, where the increased seismicity is noted. As a result of the efforts to improve the safety of nuclear power plants, it is concluded that seismic hazard is reduced due to the deep automation and transfer of the main control functions of the nuclear power plant to the software package, improvement of decisionmaking algorithms in the event of an earthquake and other emergencies. One of the main goals of defense in depth is to block the dangers of human error and the combination of equipment failures and the errors of operators and managers. Safety systems should turn on automatically and block the actions of the NPP operator for a while. Sealed shells (containers) and placement of containers with a large amount of boron solution over the reactor, which is poured onto the reactor in the event of an accident and neutralizes radioactivity in case of its occurrence, are an effective protection for power units built in recent decades. A more detailed analysis of the seismotectonic situation of the sites of existing nuclear power plants in the world has led to the need to increase the acceleration of safe shutdown in several nuclear power plants. When designing a nuclear power plant, it is not enough to take into account the magnitude and intensity of the alleged earthquakes for engineering calculations, it is necessary to use specific vibration parameters. Among them, acceleration of the soil occupies the most important place, by which it is possible to judge with maximum confidence the potential loads on structures and equipment in the earthquake zone. The modernized seismic protection system (SSZ1M) of power units is characterized by reliability, the absence of false alarms, the stability of parameters in time, and protection against external unauthorized influences.

The author estimates the impact of PR technologies on the development of nuclear power in Russia and in a number of foreign countries (USA, China, Japan, France). It is determined that as soon as at the stage of development of nuclear generation projects and other nuclear industry facilities, the use of public relations (PR), with a targeted impact on public opinion and interaction with target audiences (TA) at its core, has a significant impact on decision-making in favor of the construction of nuclear power plants, minimizes the protest behavior of the population. It is shown that the advantages of nuclear power among alternative energy sources for strengthening the socio-economic potential of states and increasing their environmental well-being are most clearly, quickly and effectively disclosed through using public relations tools. PR enables to form an adequate and correct understanding of the physical and chemical foundations of nuclear power engineering, the main threats and systems for their minimization or complete elimination at the conceptual, socio-psychological and socio-logical levels, as well as to form, in terms of specific objects and tools, the technological and organizational facilities for the development of nuclear energy projects both in Russia and in foreign countries. The activities of foreign and Russian companies aimed at ensuring loyal public opinion in relation to nuclear projects are critically described and analytically compared. The chronological framework covers the recent period: from the beginning of the 2000s to 2020. This period is noted as the most significant for the development of nuclear power in the world. Statistical data on changes in the attitude of the public in different countries to the prospects for the development of nuclear energy after the Chernobyl and Fukushima-1 disasters are presented. It is concluded that it is PR in its integrated application that contributes to government decision-making and public support in the construction of nuclear power plants in Russia and abroad.

Quake-induced accident of Fukushima nuclear power plant in 2011 triggered heated argument about the country’s energy policy in Japan. Although many people recognized the risk of nuclear energy use, they did not necessarily support the option of abandoning the technology for the near future. This paper focuses on how people perceive risks associated with and without nuclear power generation and how perceived risks affect their opinion. We conducted questionnaire survey targeting 18–20 year old university students, the stakeholders in the future. The survey was implemented in 2013–2014 when none of Japan’s nuclear power plants was in active use. Three quarters of the respondents answered that a future with nuclear power generation was more realistic than without it. The aspects dividing the two groups, i.e., respondents who expect a future with or without nuclear energy use were their evaluations of three themes: (1) the feasibility of renewable energy sources, (2) the impacts in the safety of developing nations’ nuclear power generation, and (3) the difficulty in gaining the acceptance of residents near the power plants. Meanwhile, both groups above were similarly positive about technological innovation, and were similarly and strongly negative about developing safety management.

In the landmark Slowakische Republik v. Achmea BV judgment, the ecj arguably took a resolute stance against the compatibility of International Investment Agreements between EU Member States and the inherent functioning of EU’s legal order. However, the issue as to whether the foreign investment protection regime is at odds with the sound application of EU law is far from being settled. Furthermore, the international investment protection regime as interpreted by investment tribunals may hamper EU Member States’ regulatory space, especially in the implementation of ambitious environmental and climate policies. The recent surge of litigation before international investment tribunals triggered by retrospective changes to supporting schemes for renewable energy sources and the phase-out of nuclear power plants in some European Member States is a telling example. The purpose of this article thus is to analyse the avenues currently available to ensure consistency between EU’s environmental and climate policies as implemented by EU Member States and the investment protection regime as applied by investment tribunals in the wake of the Achmea decision, with a view to devising a benchmark to prevent and avoid, rather than foster, policy conflicts.

Energy security and stability are currently the main issues throughout the world. Applied research is carried out all over the world in order to increase a share of renewable energy sources in the overall task of energy generation. In near future environmentally friendly energy sources should be found that will enable the mankind to cover its energy needs. Renewable energy sources are currently offered worldwide as an environmentally friendly and acceptable solution; however, one may always wonder whether it is realistic to expect such energy sources to be developed at a level sufficient to meet the mankind’s ever increasing energy needs. This caution is caused by the following facts associated with the renewable energy sources available today: the wind energy is not everywhere available in sufficient quantities, solar energy is not sufficiently used, hydropower (we refer to small hydro power plants), is not big enough for this quantity of energy, geothermal energy can be optimally used only at places where thermal energy from the inner core of the Earth is near the surface, tidal energy (energy of the waves) has great potentials but is very little used due to its scarcity and non-accessibility, bioenergy, as a substitute for conventional fossil fuels, is not completely environmentally friendly or acceptable due to the emission of greenhouse gases in the atmosphere. On the other hand, without implementing the adequate policies in the energy sector operation, it is not possible to have any industrial, economic or social progress in the world. Energy security and stability are only one part in achieving the ultimate goals: sustainable economy, clean environment, high standard of living, prosperity and health of the population. In the light of all the above, the paper will investigate the state and perspective of renewable energy sources with a special emphasis on the potential of solar energy.

This chapter focuses on two partial and one full policy reversal on nuclear politics in Switzerland since the 1970s. The occupation of the construction site of a planned nuclear power plant in 1975 marked the first turning point in nuclear energy policy, ending a period of pro-nuclear consensus. This protest event led to a ten-year moratorium on the construction of new nuclear power plants. The second partial reversal came in 2003, when the construction of new plants was planned. The third, full policy reversal came after the Fukushima catastrophe, which led to the decision to phase out Swiss nuclear power plants. The chapter stresses two Swiss specifics: the high importance of direct democracy on the nuclear issue, as the issue opposition can launch initiatives and de facto subject any nuclear energy decision to referendum, and the comparatively minor role of the Greens because of their lack of issue ownership.

In the next decades many facilities are going to be decommissioned in Germany. On the basis of the agreement between the utilities and the Federal Government on the phase out of nuclear energy use for commercial electricity generation predictions can be made on the schedule of the shut down of nuclear installations in Germany and a prognosis might be given for the complete amount of decommissioning waste that will arise. 17 nuclear power plants and other nuclear installations are to be shut down and decommissioned within the next 2 decades. An approach for the prediction of the amount of radioactive waste and an overview on the underlying assumptions is given. The prognosis for the expected radioactive waste in Germany depends on several assumptions. Utilities in Germany expect approx. 5000 m3 of radioactive waste with negligible heat-generation from decommissioning per reactor. New inquiries seem to indicate that less radioactive waste may arise due to new techniques in decontamination and conditioning. Nevertheless, there will be limits due to costs and physical properties.

This paper focuses on the analysis of trends in the development of nuclear energy in selected European and non-European countries in the context of the pace of renewable energy development in the world. The perception of Poles related to their openness to various energy sources against the background of European trends was also examined, as well as their ecological approach to the quality of the environment in this context. The survey was carried out using the Computer Assisted Web Interview (CAWI) technique. The total number of correctly completed forms was 923. To identify the ecological attitude, purchasing attitude, and the perception of nuclear energy, the research tool contained a number of statements on the issues studied, and the respondents assessed compliance with their opinion using a seven-point bipolar scale. The semantic differential was also used to gather opinions on the characteristics of nuclear energy. This paper shows that global trends are promoting the development of unstable renewable energy sources and the reduction of the share of nuclear power plants as an energy source. It has also been shown that the Organization for Economic Co-operation and Development (OECD) countries are more skeptical about nuclear power than countries that do not belong to the OECD (for example, China and Africa).
