In recent years, the scale of environmental hazards has been growing, emergencies occur more often at special facilities, in particular nuclear power, the largest of which was the accident at the Chernobyl nuclear power plant in Ukraine on April 26, 1986. With the advent of nuclear power, it was believed that nuclear power reactors were safe enough, control and monitoring systems, protective screens and trained personnel would guarantee their trouble-free operation. There is also a trend now that nuclear power is "environmentally friendly" because it provides a reduction in greenhouse gas emissions with replacing power plants working on fossil fuels. Some countries, such as the United States, have recently classified nuclear energy as a renewable energy source. Despite this, nuclear power is potentially dangerous due to: - possible accidents at power plants, accompanied by the ejection of radioactive materials into the environment; - ejections of about 250 radioactive isotopes into the environment as a result of the operation of nuclear reactors; - emissions of 85Kr, which changes the electrical conductivity of the atmosphere. This gas behaves like a greenhouse gas in the atmosphere, thereby contributing to anthropogenic climate change on Earth; - pollution of the biosphere with plutonium; - radioactive waste is the most important cause of environmental hazard, which remains unresolved. Civilian nuclear power reactors operating throughout the world annually generate large amounts of low-, medium- and high-level radioactive waste. Radioactive pollution accompanies all parts of the complex production of nuclear energy: the extraction and processing of uranium, the operation of nuclear power plants, the storage and regeneration of fuel, which has a significant impact on the environmental friendliness of nuclear energy. In addition, up to 300 natural and technogenic emergencies are registered annually, as a result of which people die and great economic damage is caused. The main reasons for the occurrence of technogenic accidents and catastrophes and the strengthening of the negative impact due to the occurrence of natural and technogenic emergencies in Ukraine are: obsolete fixed assets, in particular for environmental purposes; large volume of transportation, storage and use of hazardous substances; the emergency state of a significant part of public utility networks; insufficient investment support for the process of introducing the latest resource-saving and environmentally friendly technologies in environmentally hazardous industries, primarily in the metallurgical, chemical, petrochemical and energy sectors; environmental problems associated with significant changes in the state of the geological and hydrogeological environment and caused by the closure of unprofitable mining enterprises and mines; unwillingness of economic subjects to take measures to prevent accidents and catastrophes at high-risk and potentially hazardous facilities.

The book consists of 8 parts: Energy Informatics, Electric Power Engineering, Heat Power Engineering, Nuclear Power Engineering, Renewable Power Engineering, Fuels, Transport, and Environmental Safety. The results presented in this book are aimed at solving some of the technical issues proposed by the Ukraine Recovery Plan and other important scientific and applied problems in the field of energy. Scientists from leading Ukrainian academic institutions and universities are working on this book. This book is for scientists, researchers, engineers, as well as lecturers and postgraduates of higher education institutions dealing with energy sector, power systems, ecological safety, etc.

This book describes new energy saving methods and technologies for heat power engineering. The book is devoted to topical issues of energy and related industries. Leading Ukrainian scientists from both scientific institutes and educational universities took part in its creation. The research results are presented in 6 parts: electrical engineering, heat power engineering, nuclear power engineering, fossil fuels, cybersecurity and computer science, environmental safety. Results of regulating of operating modes and applicability of model checking technique in power systems are showed. Separate block of questions regarding the functioning of nuclear power plants, their waste and preventive measures of protection against negative effects on living organisms (including, for example, the Chernobyl nuclear power plant) is considered. The results of the peculiarities of the extraction, purification and use of fossil fuels are presented. In some chapters, presented the results on improving the cybersecurity of energy systems and its resilience to various threats, including the use of 5G technology. Traditionally for this series, issues of ecological safety, the impact of different energy systems on the environment and its protection are considered. A book is for researchers, engineers, as well as lecturers and postgraduates of higher education institutions dealing with energy sector, power systems, ecological safety, etc.

This book examines the problems in the field of energy and related areas (including chemistry, transport, aerospace, construction, metallurgy and engineering) that Ukrainian scientists are currently investigating. The research presented focuses on ensuring the operational reliability, durability and safety of energy equipment, as well as the development of control, diagnostics and monitoring systems in the energy sector. Further, the book explores the ecological consequences of energy facilities , particularly environmental pollution in large cities and industrial areas. Written mainly by representatives of the Council of Young Scientists of the Department of Physical and Technical Problems of Energy at the NAS of Ukraine, it is intended for researchers and engineers, as well as lecturers and postgraduates at higher education institutions interested in the control, diagnosis and monitoring of energy facilities.
