Improving the means of protecting mobile nuclear and radiation hazardous objects (NRHFs) from kinetic impactors should be achieved through the use of new materials, the use of multilayer structures with separated and multi-oriented layers, the use of rebound properties, and the refraction of the impactor's trajectory during the passing through barrier. The article presents some results of experimental studies aimed at making constructive and technical solutions implementing various principles of mobile NRHF protection.

Using surface water objects for water supply and disposal systems of nuclear power plants (NPP) produces a complex of problems concerned with environmental and health protection. Sanitary-hygienic (including hydrochemical and micro-biological) parameters and natural water toxicity are studied at Neman river, as the river is planned to be a cooling pond of Baltic NPP, which is under construction. Water quality assessment is done based on the observed data during 2011–2016. Observations have shown high variety of river condition during the year (seasonal variations) with not good enough water quality parameters for water supply purposes over the most part of the year. To obtain water with high organoleptic indicators and an acceptable level of risk in terms of chemical and microbiological composition for water supply system, a complex of methods for water purification, post-treatment and disinfection should be applied. Although, it is shown, that natural waters of the Neman river within the Kaliningrad region should be considered not to have a toxic effect on aquatic organisms.

The study experimentally showed the possibility of quantum dots formation based on three-component InGaAs solid solutions of various compositions on the surface of GaAs by the method of ion-beam deposition of quantum dots. The features of the technology of ion – beam deposition are considered. The optimal ratios of the of the GaInAs solid solution components are determined at which the quantum dots are characterized by the smallest dimensions, and the technological conditions are established where their density increases. The results of the study of the photoluminescence spectra and the surface morphology of the obtained nanostructures are presented. The results obtained may be of practical interest as materials for the formation of highly efficient solar cell panels on their basis, which are widely used as alternative environmentally friendly energy sources in the energy sector at present .

The paper considers the features of designing a special electronic component base (ECB) for automatic control systems and control of nuclear power plants. Unlike classical potential digital devices, ECB of this class is based on the properties of current logic elements (CLE). A more complete and systematic presentation of the main provisions of the CLE synthesis is given. The synthesis process of functions of the main functionally complete system using sets of logical arithmetic and logical operations is described. Directions for further research in the field of current ECB are formulated. Linear representations of logical functions of Boolean and linear algebra are discussed for two-valued and three-valued logics. The basic components of CLE are considered. The schemes that implement logical operations in various bases - “truncated difference”, “difference modulus”, “comparison” as well as their combinations are presented. The advantages of CLE compared with potential digital logic elements are shown.

This work is focused on solving real problems of a WWER reactor. The problem of simulating a fuel rod and a fuel rod with gadolinium in WWER is solved, exactly, it is analyzed for how many design layers is necessary in the fuel rod and fuel with gadolinium rod. The work contains the dependence of the deviation of the multiplication factor of neutrons from burnout. To solve these problems, the GETERA-93 and WIMS programs are used. SIMPLE FORTRAN was used for data preparation.

The paper presents the variant of the scheme of precise positioning of the suspension device for pointing at the fallen WWER reactor cassette. The scheme is offered instead of the applied load-lifting device with long telescopic links.

The purpose of the study is to study the possibility of Renyi entropy applying to monitor the condition of nuclear power plant equipment and the ability to detect faults in this equipment. In the present work processing of video images obtained with the help of a thermal imaging control system at Rostov NPP is performed. For this purpose a program is developed for the Renyi entropy calculating of the 0th, 1st, and 2nd orders for video images, as well as an analysis of the time variations of the 0-order, 1-order, 2-order Renyi entropy for detecting malfunctions in nuclear power plant equipment. Calculation of entropy indicators allows to obtain important qualitative and quantitative information about the structure of complex physical systems, the features of their dynamic evolution and about the physical processes taking place in such systems.

This article presents information on assessment of erosion and corrosion deterioration development of pipeline components using the magnetic anisotropy measurement method. The purpose of the research is fixing of locally stressed areas which are typical for local wall thinning in zones with probable erosion and corrosion deterioration and determination of magnetic anisotropy parameters as well as formation of measurement results database. 

The Russian Federation Criminal Code provides for responsibility for stealing or extortion of nuclear materials and radioactive substances in order to ensure nuclear and radioactive safety and protection of especially dangerous objects from potential threats. The article presents an analysis of this crime taking into account the changes made to the current criminal legislation. The author considers the problems associated with the use of the analyzed crime and makes proposals for their legislative solution.

The article is devoted to the substantiation of the leading role of the supporting universities of the Rosatom State Nuclear Energy Corporation (Rosatom State Corporation) and their regional branches in the territories where nuclear power facilities are located in the formation of a high level of safety culture among future nuclear plant staff in Russia and abroad in technical, socio-cultural and economic aspects. The need to analyze effective tools is updated by the development of Rosatom State Corporation export-oriented strategy. Analysis of data from sociological surveys, historical references, materials provided by organizations, and previous researches by a group of authors revealed an effective approach to building a safety culture among foreign students. It is based on the multilateral cooperation of the educational organization with the industrial enterprises of the Rosatom Group of Companies, the machine-building cluster as well as its specialization within the framework of the distributed campus of the state institution high school.
