7Ве isotope is one of the few radionuclides, the content of which in the atmosphere does not depend on anthropogenic factors. Consequently, it can also be used as a monitor to identify sources of technogenic radionuclides entering the atmosphere such as emergency situations at radiation hazardous, chemically hazardous facilities. The article presents the results of monitoring the content of the 7Ве radioactive isotope in the surface atmosphere in the Rostov region for a ten-year period from 2001 to 2011, covering the second half of the 23rd and the first half of the 24th solar cycles. The data obtained confirm the inverse dependence of the average annual volumetric activity of 7Ве cosmogenic on solar activity. The observational data allowed for the first time to carry out a comprehensive study and to reveal correlations between the volumetric activity of 7Ве cosmogenic with the main meteorological parameters such as: air temperature, wind speed, precipitation, relative humidity and atmospheric pressure.

Technogenic pollution of environmental objects determines the relevance of work on the analysis of ensuring environmental safety requirements during the operation of nuclear power plants when copper ions enter water bodies with discharges from nuclear power plants. The paper analyzes the dynamics of both actual discharges of copper ions for Balakovo NPP, Novovoronezh NPP and Smolensk NPP (t / y), and in fractions of the normative permissible discharges for this heavy metal (%). The absence of violations of environmental safety requirements is shown. A more detailed analysis was carried out for the Rostov NPP. It is shown that the modernization of the turbine condenser pipe systems of the power unit No. 1 led to a sharp decrease in the flow of copper ions into the cooling pond from the nuclear power plant. Analysis of the toxicant content dynamics in the water of the cooling reservoir and the Tsimlyansk reservoir did not reveal the effect of the influx of copper ions from the cooling reservoir with filtering water on their concentration in the reservoir water.

Southern Iran in the area of Zagros and the borders of the Arabian and Eurasian plates is a seismically active territory in which large industrial facilities are located, including Bushehr NPP. In this regard the relevance of studying modern geodynamics and geology of the region is understandable. The geological structure of the territory after engineering surveys of 1974-2001 no longer seemed questionable. However, after completion of engineering surveys for new NPP units in 2015, new views on some positions on seismotectonics, and later on the geology of the area, appeared. The article provides information about the geology, tectonics and stratigraphy of the region and the research area, including not covered earlier in domestic reporting materials and scientific articles, and also considered the possible reasons for the appearance of other interpretations regarding seismotectonics and geology of the area where the NPP site is located. A brief analysis of the research results, both previously completed and completed relatively recently, is presented. An additional argument is considered in favor of the presence of fault zones within the Bushehr anticline proposed by Iranian researchers. In particular, the Khark-Mish fault supposed by them may be part of the buried ancient anticlinal fold before the position of its axis changes in the modern period as a result of neotectonic processes common to the region as a whole. The geology and tectonics of the Bushehr anticline are compared with similar structures on Fr. Hark and the nearest islands. Updated information on the stratigraphy of individual geological formations of the region and the research area is also provided. In spite of the reasoned justification of various positions on the geology and tectonics of the region, it seems necessary to conduct a number of additional special direct and indirect studies aimed at ensuring the safety of the Bushehr NPPs under construction and operating.

The article discusses the issues of increasing the accuracy of measurements which is especially important in the installation and operation of technological equipment. The paper presents a technique for studying the accuracy of determining the rectangular coordinates of the controlled points measured by an electronic tacheometer. It is proposed to use a precision laser tracker for metrological standardization of high-precision electronic tacheometers at short distances (up to 60 m). The results of practical testing of the proposed method of metrological standardization of a high-precision electronic tacheometer are presented.

The paper present the calculation of the strength and rigidity of the removable gripper for moving and turning ellipsoid bottoms of hull equipment. The proposed design solution will reduce the labor and material consumption of technological equipment and eliminate the need for welded load-handling and installation elements.

Long-lived minor actinides (MA) like, Neptunium, Americium, and Curium are the major burden of nuclear power. Long-lived MAs have not yet been burned as nuclear fuel. Therefore, the transmutation of long-lived MAs is introduced as an alternative to direct final disposal. In current work, we compare the performance of MA transmutation in a critical Single-fluid Double-zone Thorium-based Molten Salt Reactor (SD-TMSR) and a Small Molten Salt Fast Reactor (SMSFR). We study the dynamic of K_eff and core reactivity with different MA loads, shift of the neutron spectrum, time evolution of MA and basic nuclide inventory, as well as the transmutation coefficient (TC). The TC of long-lived MA is calculated using the Monte Carlo code SERPENT-2. The total neutron flux in SD-TMSR and SMSFR can reach 4.1x10¹⁴ and 1.8x10¹⁵ n/cm²s, respectively. The results show that SD-TMSR consumes about 50% of the generated Pu isotopes in the fuel salt, however, SMSFR consumes about 86.5% of the generated Pu isotopes. During burnup, we apply online reprocessing and refueling, so the core remains critical, and the total mass of fuel in the core and in the blanket is practically constant. The results show that both reactors efficiently transmute²³⁷Np,²⁴¹Am,²⁴³Am and²⁴³Cm, while SMSFR has a higher TC than SD-TMSR. TC of total MA reaches 54.84% and 87.97% in SD-TMSR and SMSFR, respectively.

The article deals with the results of empirical modeling of the oil system of the main circulation pumps of a nuclear power plant, designed for oil supply to support bearings and their cooling. The empirical model extends the industrial monitoring platform with a sliding linear predictor to maintain the operational safety and operability of the MCP. The initial data for the predictor are the controlled parameters of the MCP.

As part of the experimental assessment of the stress-strain state of pipeline elements at the NPP using devices based on the magnetoanisotropic method, the criteria for the parameters of the main mechanical stress difference characterizing the increased probability of erosion and corrosion wear were obtained. It is determined that the high level of the main mechanical stress difference values in combination with the results of processing measurements on the parameters of the first derivative and the gradient of the main mechanical stress difference, depending on the scanning step in the grid nodes, are additional criteria for detecting a potentially dangerous area of erosion and corrosion wear.

The main factor of destruction of fuel rods in accidents with loss of coolant is associated with the vapor-zirconium reaction occurring between the fuel rod shell and the coolant (water). Improving the reliability of fuel cells can be obtained by modifying or replacing the fuel shell, materials that do not interact with the coolant during normal operation and in emergency situations. Increasing the reliability and economic characteristics of nuclear power plants is possible by replacing uranium dioxide with fissile compositions with a high content of fissile isotopes and with greater thermal conductivity. These two provisions form the concept of ATF (tolerant fuel). Variants of creation of tolerant fuel are considered., variants of modernization of shells and fissile compositions are studied for nuclear power plants with WWER reactors.

The paper considers the possibility of using coaching as an innovative and effective technology for managerial interaction with personnel in the daily activities of the nuclear power plant leaders. The results of diagnostics of the development of management skills of managers at the Rostov nuclear power plant are presented. The obtained results of the study can be used as the basis for the strategy of forming and increasing leadership in matters of safety culture at the enterprises of the nuclear industry

Due to the COVID-19 coronavirus infection pandemic, the world is faced with the need for social isolation and a forced rapid transition to a “home office” and online learning. The Russian education system has almost completely switched to distance learning. Working in the new conditions turned the daily routine of both teachers and students who not only faced difficulties of various nature but also discovered new opportunities for professional growth. Traditionally, it is customary to discuss the disadvantages of distance education, but this paper considers the advantages and new opportunities of this form of education. This is especially important in the process of mathematical training of university students focused on work in the nuclear industry due to the specifics and importance of studying this subject and due to the fact that at present online training is widely implemented in the training of employees of nuclear power plants where digitalization and everything which is associated with remote access technologies, thanks to the pandemic, are in demand and irreplaceable.
