AbstractNuclear power is an important component of the global response to climate change. Nuclear power provides continuous electricity and can overcome the intermittency of the renewable energy sources dependent on wind and sun. Assurance of nuclear safety is essential for further expanding nuclear power as a part of the global response to climate change. The commitment to safety must be a universal priority, as the prospects for nuclear power everywhere would be adversely influenced by the public outcry following a serious nuclear event anywhere. The importance of the global nuclear safety regime was revealed by the accident at the Fukushima Daiichi NPP. The accident reinforced that in addition to the need to have a competent national nuclear safety system in place, it is ultimately important to have an international system that ensures that the relevant national institutions diligently and effectively fulfil their roles. This chapter examines the current global nuclear safety regime and suggests improvements, including through safety inspection, greater transparency measures, increased harmonization of standards, and others.

This paper intends to give an overview on some results of our studies carried out on the public opinion of the above aspects (settlements’comfort level and the use of renewable energy sources) directly or indirectly linked to the topic of climate change and possible adaptations.These studies were carried out by applying questionnaire survey in the (altogether 25) settlements of the Gyöngyös Micro-region.Knowledge on general human perceptions related to climate change and its impacts is considered to be important as it should advance theelaboration of adaptation and applied scientific works. They are highly required as rural areas, due to their closer relationship (dependence)to the physical environment, are more susceptible to changes resultant from the climate change with their possibilities to adaptation alsobeing impeded.The beauty of environment plays an important role in the settlements studied within the micro-region with more than two third of polleesopting the environment as a factor they most proud of, especially among those residing in the villages for more than 10 years. It can bepresumed that any change in this environment would greatly impact their everyday life and emotional relationship to their home villages. Theoverall picture after analysing the public opinion on the use of renewable energy source (as possible way of adaptation to the impacts ofclimate change) is rather controversial. Even basic knowledge and information are limited regarding the relevant technologies callingattention to the importance of raising environmental awareness and providing full information seems to be essential and should beimplemented, through the media and education.

It is well known that the electrical-power generation is the key factor for advances in any other industries, agriculture and level of living. In general, electrical energy can be generated by: 1) non-renewable-energy sources such as coal, natural gas, oil, and nuclear; and 2) renewable-energy sources such as hydro, wind, solar, biomass, geothermal and marine. However, the main sources for electrical-energy generation are: 1) thermal - primary coal and secondary natural gas; 2) “large” hydro and 3) nuclear. The rest of the energy sources might have visible impact just in some countries. Modern advanced thermal power plants have reached very high thermal efficiencies (55–62%). In spite of that they are still the largest emitters of carbon dioxide into atmosphere. Due to that, reliable non-fossil-fuel energy generation, such as nuclear power, becomes more and more attractive. However, current Nuclear Power Plants (NPPs) are way behind by thermal efficiency (30–42%) compared to that of advanced thermal power plants. Therefore, it is important to consider various ways to enhance thermal efficiency of NPPs. The paper presents comparison of thermodynamic cycles and layouts of modern NPPs and discusses ways to improve their thermal efficiencies.

Several Western Balkan states face the consequences of the Yugoslavian war, which left hometowns with dilapidated electricity grid connections, a high average age of power plant capacities and low integration of renewable energy sources, grid bottlenecks and a lack of competition. In order to supply all households with electricity, UNDP Croatia did a research on decentralized supply systems based on renewable energy sources. Decentralized supply systems offer cheaper electricity connections and provide faster support to rural development. This paper proposes a developed methodology to financially compare isolated grid solutions that primarily use renewable energies to an extension of the public electricity network to small regions in Croatia. Isolated grid supply proves to be very often a preferable option. Furthermore, it points out the lack of a reliable evaluation of non-monetizable aspects and promotes a new interdisciplinary approach.

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.


Originally, coal was the main source of energy. It remains so throughout the 18th century during the period of the rapid industry development. Later on, oil and naphtha began to be used as energy sources and their usage expanded especially in 19th century. A special feature of the above mentioned fossil fuels is their long creation period – requiring millennia. They are a result of rotting of different plant and animal kinds. In comparison to the period of their formation, the period of their utilization is far shorter. In accordance with a number of existing statistics about 2050 year it may be talked about a depletion of the liquid fossil fuels, also, the world coal supplies are considered to last within the next 200 years. Therefore, the development of nuclear power engineering is considered to be one of the alternatives to generate energy. Recently, the nuclear power energy generation has been denied in many countries because of the risks associated with its generation and because these risks have been confirmed by serious accidents throughout the World. The storage of worked nuclear waste is also a problem and risky. The renewable energy sources are another possibility to generate energy.
