The increasing of the energy efficiency of nuclear power plants with fast neutron reactors by utilizing waste heat using heat pumps

Today, an important task for the economy is to increase the efficiency of using primary fuel. At present, for nuclear power plants with VVER reactors, thermal efficiency is about 33%, with fast neutron reactors-more than 40%. This means that most of the heat produced is released into the atmosphere. In this paper, we consider methods to solve the problem of increasing energy efficiency by the example of NPPs with fast neutron reactors due to the utilization of low-grade waste heat. The results of practical implementation of utilization of low-potential thermal energy of thermal and nuclear power plants using heat pumps were generalized. The analysis of the utilization efficiency of waste heat from various NPP systems was performed. © Published under licence by IOP Publishing Ltd

РЕВІТАЛІЗАЦІЯ РІЧКИ УСТЯ В МЕЖАХ МІСТА РІВНЕ

The article gives an analysis of modern experience on therevitalization of small rivers converted into artificial channels in cities and other urbanized territories. Based on the analysis of the role of small rivers in the formation of urban spaces, the key principles for the restoration of small rivers are given. In particular, the revitalization of the river with maximum approximation to the level that preceded the intensive industrial development of the adjoining territories obliged to study the history of the river, to determine its historical hydrographic and hydrological characteristics, to study the changes in river basins. On the basis of this study the complex of the main factors, which led to changes in the hydrological regime of the river and as a result to of deterioration of the ecological status of the river and its floodplain, are determined. Proposed organizational measures and corresponding constructive and technological solutions to ensure the compliance of Ustya river with the main recreational andecological requirements.From the analysis of historical data it was determined that in theyears 1932-1939 significant work was carried out on clearing andfixing the channel of the Ustya River, the elimination of wetlands. Itwas made of fastening the shore by the brushwood with weaving ofverbena to form directly the channel and fixing the shores formed by sloping slopes with fastening the sowing of grasses. Obviously, the width of the channel formed in the late 30-ies of the twentieth century was no bigger than the current one, which testifies (taking into account the higher flow of water) about the greater depth of the channel and the faster flow. The revealed historical features of the formation of the channel of the Ustya River allow us to recommend restoring the hydraulic connection of the groundwater of the floodplain of the river with the channel by replacing the part of the existing reinforced concrete fastening with a historically justified fastening. The riverbed is recommended to be fastened with a perforated sheet piles and slopes – with a geogrids and cell filling with soil and sowing perennial grasses.Also, to saturate with water oxygen is recommended to create localobstacles in the form of low thresholds of natural stone. To avoidwaterlogging of the surrounding area, it is necessary to drain thewaterlogged areas of the floodplain, as well as to organize thecleaning and admission of rainwater from the adjoining territories tothe river.В статье приводится анализ современного опыта по ревитализации малых рек, преобразованных в искусственные каналы в городах и других урбанизированных территориях.

MODEL FOR ASSESSING DIGITAL LEADERSHIP OF ORGANIZATION

A mathematical model of the level of development of digital leadership in leading scientific and technological sectors has been proposed. The assessment is proposed to be carried out in five main areas, each of which includes both quantitative (for example, the share of modern (digital) training areas in the total number) and qualitative criteria (for example, the speed and effectiveness of interaction between the organization’s departments).Using the lower level of the hierarchy, the criteria of one direction are compared in pairs by the strength of their influence on the key direction as a whole. As a result, a matrix of pairwise comparisons is created. The level of development of digital leadership is characterized by an aggregated indicator calculated on the basis of the normalized matrix vector. The assessment methodology can be used both by organizations in the scientific and technical sectors (universities, institutes, research centers, etc.), and by government bodies responsible for the implementation of activities related to digitalization

Scanning Electron Microscopy Study of Drilling Cuttings in Tomsk Oblast Sites

The research is focused on determining mineralogical composition of drilling cuttings by scanning electron microscope as well as imaging the sample surface of high resolution that allows studying the structural characteristics of the site. In addition, a number of other techniques permit obtaining information on chemical composition of sample in near-surface layers. The study in drilling cuttings by means of scanning microscopy has revealed the presence of titanium, iron, zirconium oxides, iron sulphide, barium sulphate. The former is a mineral that concentrates rare-earth elements, presumably monocyte, as well as uranium silicate, etc. The results obtained confirm the data of previous X-ray structural analysis, i.e. the study samples consist of alumosilicate matrix. Apart from silicon and aluminium oxides, the matrix includes such elements as Na, K, Mg. Such a composition corresponds to rock-forming minerals: quartz, albite, microcline, clinochlore, muscovite, anorthoclase

Implementation of a Policer-Based Control Loop for the Dynamic Resource Allocation of a Software-Defined Communication Infrastructure

The use of solutions based on the principles of virtualization is designed to increase the efficiency of using the communication infrastructure due to the dynamic distribution of existing communication and computing resources between their virtual components. The software management of the communication infrastructure components opens up opportunities for applying new approaches to solving the currently very urgent problem of ensuring the required Quality of Service. Taking into account the current trends in the development of communication infrastructures and means of their automation, it seems relevant to build systems that implement a closed cycle of communication infrastructure resource management based on traditional and promising tools for monitoring and managing QoS and studying its behavior. Closing the control loop is achieved by implementing a control script that automatically responds to changes in the transmitted data and makes decisions about changing the current configuration of network devices. One of the approaches to building a closed control loop is to change the physical bandwidth of a virtual communication channel depending on the intensity of its resource use. The paper considers an example of the implementation of a closed control loop based on the rules of the policy for limiting the rate of sending packets of heterogeneous traffic and compares the approach of dynamic bandwidth redistribution with traditional approaches. © Published under licence by IOP Publishing Ltd
