The Study of Possibility of Stress-Corrosion Cracks Group Resolution by Eddy-Current Flaw Detector
Authors: Moskovkina V N , Zagidulin R V 
Published: April 2020

Abstract
The question on the possibilities of spatial resolution for a group of stress-corrosion cracks in the body of a steel pipe under eddy current control was considered. Using a VD-12NFP eddy current flaw detector, stress-corrosion cracks on specimens with artificial defects were investigated. Specimens were made according to the results of statistical studies of linear dimensions and the location of stress-corrosion cracks of operational origin in a section of the main gas pipeline. In the course of the research, it was revealed that it is possible to achieve sufficient spatial resolution for a group of stress-corrosion cracks in the pipe body using signals from a detachable eddy current probe (ECT) of the transformer type, which is part of the eddy current flaw detector. For this, the diameter of the probe core should not exceed the interval between adjacent defects in the group of cracks. The signal half width of the detachable eddy current probe installed above the defect is an informative parameter for the eddy current probe signals. It depends on the number of defects in the stress-corrosion crack group.

Published: April 2020

Abstract
The topic of low-power nuclear power plants has been relevant for more than 50 years. They allow you to conduct electrical energy in remote areas, such as, for example, the Arctic, and to build stations with the possibility of mobile regulation in cases of emergency. Currently, the state corporation Rosatom has launched a broad propaganda about the prospects of these nuclear power plants and has stepped up the construction of the first floating nuclear thermal power plant, which is one of the variants of this type of nuclear power plants. The idea of creating this project has generated a mass of protests from environmental organizations.
In this paper, the scenario of a beyond design basis accident at a floating nuclear power plant is considered. Calculation of the damaging factors of this accident. The calculation of prevented damage was made using the existing methodology with some changes made for convenience of calculation, and a formula was introduced for comparing the costs of measures to prevent damage with the magnitude of this damage. The improved methodology can be used in the EMERCOM of Russia system for forecasting emergencies at the facility level. The introduction of this methodology and its practical application for the assessment of prevented damage will make it possible to predict the consequences of the occurrence of emergency situations on energy-saturated objects, objects with a massive presence of people.

Abstract
Steppe zone in the Orenburg region is subject to a powerful anthropogenic load. Most of the territory of the steppes is plowed, and the rest of the land is adapted for pasture or is a Deposit. In addition, fires are a serious threat to the biodiversity of the region’s ecosystems. Fires affect the phytocenosis and cause substantial conversion of plant communities. The level of exposure may vary depending on the frequency of the fire, timing and intensity. In recent years, the spread of steppe fires in Russia and their frequency have acquired an extraordinary scale. The climatic conditions of the region (dry, hot summers and long atmospheric droughts) contribute to the spread of fires in large areas. In order to trace the restoration of steppe ecosystems after a fire we have investigated the dynamics of stocks of aboveground phytomass in the 2015-2017 periods, the article considers the initial stages of the leftover post-fire changes in grass communities (Festuca valesiaca, Stipa zalesskii, Artemisia austriaca, Herbae stepposae). Studies have shown how components of above-ground phytomass (live phytomass, rags, litter) accumulate and distribute in the community after a fire. A comparison with similar unburned grasses (Stipa zalesskii, Poa transbaicalica, Herbae stepposae) community with Spiraea crenata. The change of dominant species in the phytocenosis, reduction of the total projective cover in comparison with the control was revealed.

Abstract
This article provides results of mineralogical and geochemical studies of granodiorites of the Kuldur low-mineralized thermal water reservoir. The site of geological and groundwater studies belongs to the Pionerskii massif located within the Lesser Khingan block of the Bureya compoite terrain. Granitoids of the Tyrma-Bureya assemblage in the Pionerskii massif are considered to have formed in the early Mesozoic era, not in the late Paleozoic era, as deemed before. Granitoids of the assemblage under study were likely formed in the geodynamic backdrop of the collision of the North Asian and Sino-Korean cratons.
Analysis of Longitudinal Stresses in Main Pipelines with a Long Operating Life

Published: April 2020

Abstract
With the advent of the possibility of determining the actual bending radius of long-operating main pipelines by pigging inline inspection tools, it became clear that up to 100% of trunk lines cannot provide elastic bend radius within the limits required. Assessing the that requirement for bending radius to be of not more than 1000D, it can certainly be considered justified in relation to construction of new trunk lines, but for most long-operating main pipelines, this requirement conflicts with its actual stress-strain state. Re-lay them for this reason, due to the scale of the problem is not possible. At the same time, a sharp increase in accident rate is also not observed, as a result of which we can conclude that it is necessary to revise the existing regulations for the limiting values of permissible elastic bend radius.

Published: April 2020

Abstract
The state-of-the-art of relevance and prospects of using alternative fuels for heavy-duty dump trucks as an effective way to reduce the anthropologic impact on the environment is considered. The analysis of the combination of factors (economic, technological, engineering, safety) determining the possibility and prospects of using alternative fuels in the operation of heavy-duty dump trucks in mining industry is carried out. The data are presented on the available experience of using environmentally friendly (alternative) fuels for heavy-duty dump trucks: electric energy, liquefied petroleum gas (LPG), com-pressed natural gas (CNG), liquefied natural gas (LNG). The studies conducted show that liquefied natural gas (LNG), for a number of objective reasons, seems to be the most promising alternative to diesel of all possible fuels in the segment of heavy-duty haulage vehicles. It is said that in Russia, in the Kemerovo region, for the first time, within the framework of one group of companies, an integrated project for the production of liquefied natural gas and its consumption by BelAZ heavy-duty dump trucks was successfully implemented.

Published: April 2020

Abstract
In present paper the applying of an optimization approach in modeling the effects of technological disasters are studied. Mathematical models of the pollutants propagation in the water or in air, based on the convection-diffusion-reaction equation are used. The problems of recovering the diffusion and reaction coefficients by the pollutant concentration measured in a certain subdomain are studied. In framework of optimization approach these problems are reduced to the multiplicative control problems. Solvability of considered control problems are proved and the local stability estimates are obtained. The recovering of the diffusion coefficients and the reaction from the measured concentration makes it possible to realistically estimate the intensity of the diffusion of pollutants and the effectiveness of the processes aimed at the decomposition of the pollutant (reaction coefficient).
Geochemistry of Rare Earth Elements in the Rivers and Groundwaters of Chistovodnoe Thermal Area (Primorye, Far East of Russia)
Authors: Chelnokov G A , Bragin I V , Kharitonova N A 
Published: April 2020

Abstract
The behaviour and hydrogeochemistry of rare earth elements were investigated in the surface and groundwaters of Chistovodnoe thermal area (Far East of Russia). The waters were classified according to the pH into neutral waters with pH ranging from 6.6 to 7.3 and alkaline waters with pH between 7.5 and 9.3. The REE concentrations in the river waters with pH=6.6-6.8 are markedly higher than those from the thermal groundwaters with pH=7.9-9.3. The surface water mass in the Chistovodnoe area has similar REE patterns reflected in negative Ce and Eu anomalies. The cold and thermal groundwaters are influenced by the water-rock interaction processes. Such correlations are explained by the redox changes with depth within the area. The oxidizing conditions in the shallower aquifer generate a larger Ce anomaly. The low concentrations of REE in groundwater suggest that the elements are relatively immobile during weathering and transport, being carried partly in heavy detrital minerals, especially zircon and titanite, and partly adsorbed onto clay particles. Heavy REE enrichment is explained by successive water-rock interactions supplying REE to the water in which differential scavenging of light REE by particulate matters occurs.

Published: April 2020

Abstract
The question of increasing the efficiency of industrial waste management of the Arctic is of a big importace due to the disturbance of the environment under the influence of intensive exploitation of mineral resources. The analysis of the effectiveness of the solid waste management over the past five years on the Arctic industrial enterprises such as: PJSC Novatek, PJSC ALROSA, Polar Division and Kola MMC of PJSC MMC Norilsk Nickel, Kirovsk branch of Apatit of PJSC PhosAgro, industrial enterprises JSC Karelsky Okatysh, JSC Olcon, JSC Vorkutaugol and JSC Yakovlevsky mine of Division Severstal Resources of PJSC Severstal. Based on data obtained from company reports in open access the dynamics of waste generation and utilization was investigated. It was shown that despite the fact that in recent years the Government of the Russian Federation approved a number of documents related to waste management and aimed at the formation and future development of a new industry for waste management a significant part of enterprises does not pay enough attention and does not take proper measures in the field of industrial waste management.

Authors: Tsukerman V A , Goryachevskaya E S 
Published: April 2020

Abstract
The problems of managing the Arctic transport system are considered. Particular attention is paid to the development of Arctic shelf deposits, as well as to the challenges and risks associated with the extreme conditions of transportation of hydrocarbon raw materials. Certain volumes of cargo transportation via the NSR have positive dynamics, which determines the encouraging results and allows us to develop strategic plans for the extraction of hydrocarbons and the delivery of finished products. The main promising directions for the development of sea transportation of hydrocarbons in the waters of the Northern Sea Route are outlined. Certain prospects for the development of Arctic oil and gas resources are identified. It is shown that an increase in the number of freight vehicles in the water areas of marine transport corridors in the near future will be associated with an increase in the turnover of ports and terminals. The main directions of improving the Arctic fleet and technological updates of the port infrastructure to ensure the development of hydrocarbon deposits in the Arctic seas are substantiated. The introduction in this area of the most important innovative methods for the development of the oil and gas sector is a full-scale implementation of transport and transit traffic, primarily in order to improve the system of internal corridors passing through the NSR under the jurisdiction of the Russian Federation. The directions of improving and increasing the efficiency of operation of the Arctic transport system are proposed.
