This article discusses the only Armenian nuclear power plant operation in Transcaucasia, the energy demand of the population of the Republic of Armenia, the restoration and secondary launch of nuclear power plants, environmental impact assessment, and prospects for the development of nuclear energy in the country. Data on personnel dose loads, emissions and discharges of nuclear power plants, soil and water pollution in the monitoring area for 2020 are presented.

The paper considers the construction of a very low-level waste disposal facility (VLLW) at the Rostov NPP with a volume of 11,000 m³. Information about formation and management of VLLW at Rostov NPP is given. Characteristics of 11,000 m³ VLLW disposal facility is presented. The design documentation provides for construction of the VLLW disposal facility intended for disposal of very low-level waste of hazard classes IV and V formed as a result of Rostov NPP production activities and meeting the criteria of disposal acceptability.

The object of research in this work is to substantiate the methodology of the secondary use of concrete scrap obtained as a result of the dismantling of the OUAE. In this study secondary application is considered within the framework of additive technologies. Construction using additive technologies is one of the promising areas. This line of research is part of the justification of the method of secondary use of concrete obtained as a result of the dismantling of nuclear energy facilities (OUAE).

The article deals with the relevance of solving issues to improve the energy efficiency of the use of extracted hydrocarbon fuel, as well as the feasibility of developing and applying these measures in the economies of industrially developed countries. The necessity of having a permanent reliable source of electricity when using renewable and alternative sources of electricity is substantiated. As a permanent and reliable source of electricity, it is proposed to use operating and developing nuclear power plants. The use of these power plants requires the improvement of various systems for various purposes in them. To do this, the paper presents an analysis of the parameters of the steam and gas systems of pressure compensators to ensure the necessary pressure of the coolant in the first circuit of the nuclear power plant. Analysis of the parameters of operation of these systems is presented in tabular readable form. Based on the analysis, a "hybrid" pressure compensator system is proposed for detailed consideration, which includes the positive properties of the pressure compensator systems under consideration - steam and gas. An estimated calculation of the possible use of air (or gas) in the free volume of the pressure compensator with the provision of preliminary pressure is presented, followed by bringing the value of this pressure to the required value during operation. The advantages and disadvantages of the considered systems and some issues that require detailed study are noted.

The paper presents the results of a computational and theoretical analysis of the use of various burnable poisons placed in a fuel rod for the maximum reduction in the reactivity margin compensated by a liquid system based on a boron absorber for VVER-type reactors operating in extended campaigns. Various layouts of fuel rods placement in fuel assemblies and with different concentrations of burnable poisons are considered, which are considered natural gadolinium and erbium. The analysis is carried out using simplified models of fuel burnup at partial refueling.

The paper considers the relevance and possibility of developing methodological foundations for risk-oriented strategy of nuclear power plant equipment MRO on the example of pipeline valves. The pre-design study of the information system implementing these fundamentals is described.

The paper analyses the current peculiarities of wind energy development in Russia. The importance of renewable energy sources for solving the problems of limited resources and environmental safety is defined. Some economic aspects of wind energy are given and the conclusion about insufficient efficiency and investment attractiveness of this energy generation sector is made. The positive impact of wind energy in the context of implementation of sustainable development goals is considered. The importance of territorial technological clusters for overcoming barriers to wind energy development, among which financial and regulatory factors dominate, is revealed. An example of objectives and planned results of wind energy development in Volgodonsk, Rostov region is given.

The paper actualizes the theoretical foundations and practical aspects of managing the culture of industrial safety of industrial enterprises. The structural and substantive aspects of the organization of monitoring the implementation of management decisions in the process of managing the culture of industrial safety are revealed. A general analysis of the regulatory framework defining the basis for monitoring and evaluating the culture of industrial safety on the example of nuclear industry enterprises is proposed.

The paper considers the problems of formation of culture and ethics of communication in the distance learning process when training nuclear specialists, the basic principles and methods of communication of students online, analyzes the issues of ethics and communicative tolerance of students.
