AbstractBACKGROUND: Development of nuclear power engineering and its influence on all spheres of economy defines importance of reviewing of simulation questions and an assessment of ecological safety level taking into account specific threats for agricultural production within development of agricultural radio ecology. The significant amount of the local factors defining the overall level of ecological and radiation safety requires reasons for system of the modelled indices and tools of their aggregation. OBJECTIVES: Development of mathematical apparatus and indistinct and multiple model for an integral assessment of agricultural production ecological safety in case of radiation pollution. It is necessary to solve the following problems: – reasons for system of indices and their integrated groups for simulation of agricultural production ecological safety taking into account specific threats; – to justify the structure and to realize indistinct and multiple model of ecological safety of regional agrarian production; – to enable the computer realization of the developed system of an indistinct output with the help of which to reveal the priority directions of enhancement of agrarian production ecological safety of the region on the example of the Volgograd region. METHODS: Research was conducted with use of freely extended software environment of "FisPro version 3.5", allowing to build the simulating systems of an indistinct logical output in the automated mode, and also statistical data under the terms of agrarian production in the conditions of the Volgograd region. CONCLUSIONS: 1. The system of ecological safety indices of agrarian production taking into account specific threats of radiation pollution including the integrated groups, and also local indices characterizing them for indistinct and multiple simulation is justified. 2. The two-level model of ecological safety constructed on the basis of algorithm of an indistinct output by Mamdani realized in the environment "FisPro version 3.5" allows to simulate and estimate influence of the integrated groups of ecological indices system on the ecological safety level of agrarian production of different level subjects in the conditions of specific threats of farmland pollution. 3. Enhancement of the farming standard and, first of all, maintenance of soil cover taking into account regional system of dry agriculture can be the priority direction of improving of agrarian production ecological safety of the Volgograd region.

AbstractOne of the aspects of ensuring industrial and environmental safety of nuclear power plants is the prevention of reduction of volume of industrial water supplied for cooling of equipment or exceeding the concentration of pollutants. Reducing the amount of incoming water can be caused by a decrease in the filtration capacity of the intake device, the quality degradation occurs as a result of contamination by biological organisms (clogging algae, remains of fish). At present, widely found FPS fish protection device with filter elements, which are an insurmountable obstacle for young fish and prevent it from entering the cooling system. The article analyzes the scientific papers on the study of ways to wash the filter cloths of fish protection devices, the existing theoretical methods for calculating the parameters of plane turbulent jets formed near the waterproof screen. Conclusions: 1. Method of parameter calculation of submerged turbulent axisymmetric jets formed near the filter surface (permeable screen) was not found. 2. Existing theoretical methods of parameter calculation of planar turbulent jets, emerging close to waterproof screen, and some of the theory of turbulent jets and methods for calculating jets in a drifting thread can be used in the development of methods of calculation of axisymmetric jet developing near the filter surface. 3. Jet parameters in the free development of the site are comparable with the parameters of a conventional submerged jet in the orthogonal coordinates associated with the jet axis. 4. Characteristics of a submerged axisymmetric jet on the site free of development near the filtering surface (screen) can be determined. 5. Velocity profiles in cross sections of free jet water-exchange layers can be similar, dependence with the refined exponent can be used for their description. The research results can be important in the equipment of nuclear power plant intakes with special fish protection structures.

AbstractHeat treated 9%Ni steel is considered the most suitable and economic material for construction of large-size liquefied natural gas (LNG) storage tanks which operate at cryogenic temperatures (-196°C). Strength above 700 MPa as well as a minimum impact value of 60 J are required to ensure reliable operation of the LNG tanks at operating temperature. Conventional arc welding processes, including shielded metal arc welding, gas metal arc welding, gas tungsten arc welding and submerged arc welding, are currently used in construction of LNG tanks. Ni based filler wire is the preferred filler metal of choice in LNG tank construction. The main problem with this choice is the lower mechanical properties, particularly tensile strength of the weld metal. To compensate, the wall thickness needs to be excessively thick to ensure the strength of the welded structures. Ni based filler material is expensive and a large quantity is needed to fill the multi-pass weld grooves. These factors significantly add to the cost in the fabrication of LNG storage tanks. For these reasons, exploration of new welding technologies is a priority. A big potential can be seen in laser based welding techniques. Laser beam welding results in much smaller fusion zone with chemical composition and mechanical properties similar to that of the base material. Laser welding is a much faster process and allows for a joint geometry which requires less filler material and fewer welding passes. The advantages of laser welding can help to overcome the problems pointed out above. Trials of autogenous laser welding, laser cold-wire welding and hybrid laser-arc welding conducted on the 9%Ni steel are presented in this paper. Chemical composition of the weld metal as well as effects of welding parameters on the weld formation, microstructure and tensile strength is discussed. Filler wire penetration depth as well as character of its distribution in the narrow laser welds was examined using EPMA - electron probe microanalysis.

AbstractThis work is continuation of researches of coatings made by the method of gas-powder surfacing and a supersonic gas-powder surfacing for the purpose of studying the ability of a material to resist the impact of abrasive particles. For this purpose there were performed a comparative study of weld alloys, the resistance to mechanical wear. Deposited coating samples were cut, according to the requirements, of rectangular shape measuring 4 x 5 x 10 mm, with a surfacing material of a thickness h1,2=1,0-1,2 mm, and h3,4=1,5-1,7 mm at the end. Reference samples were pre-seasoned by the standard method (heating to 850 ° C, exposure time 2 min, cooling; hardness during quenching HRC 62 in water, in oil HRC 54). The static load on a sample of this size was 8,75 kg/cm2. The value of ΔU wear weight was determined by weighing before and after tests on a laboratory analytical balance with an accuracy of 2∙10-4 g (type VLR-200). After each test the samples were removed, washed, dried. Tests were carried out at constant load P = 400 g. Under other equal conditions of testing samples from previously conducted a supersonic gas-powder surfacing, have the best resistance to abrasive wear, as a result, the weight loss of the sample is 3 times less than in the sample of gas-powder surfacing. Study of wear-resistance in the weld coating methods and powder supersonic gas-powder surfacing has revealed that the preferred method, producing samples is a supersonic gas-powder surfacing.

AbstractThe paper proposes a capacity of a full cross-section of core elements is intended for of various nuclear material storage. The stability of the bar element to a central compression is considered. Expressions to determine the critical stress beam elements are obtained. It is shown that the variation of the critical stress occurs when the coefficient of deformation of strip blanks during the creation of the hollow member is increased. Thus the critical voltages relative to the x-axis increase with the blow-up ratio, the critical voltages relative to the y-axis significantly reduce. Nomogram showing the variation of the critical stress in the direction of the central axes is provided.

Article NameMultichannel Radiation-Hardened Instrumentation Amplifier for Sensor Systems and Analog Interfaces of Demanding Application (2)
AuthorsN.N. Prokopenko, N.V. Butyrlagin, A.V. Bugakova, A.A. Ignashin

Don State Technical University, 1 Gagarin Sq., Rostov-on-Don, Russia, 344000

AbstractThe article considers the design features of the instrumentation amplifier (IA) for sensor systems, realized on the radiation-hardened microcircuits of AC_1_4, AC_2_1 (OJSC “MRIMI”, Minsk city). The new architecture of IA is developed, which can operate without resistors of common negative feedback with classical bridge measuring circuits and provides higher common-mode rejection ratio. In IA the digital control of the transfer ratio is available due to the elements commutation of the array “R-2R” by CMOS transistors. The feature of the suggested IA lies in application of the transistors of various physical natures in its input stage – Bi-JFETs and JFETs. The use of the complementary CMOS transistors in the input stage of IA is prospective, besides one of them must have an internal channel and another one - an induced one. The low offset voltages and the absence of classical sources of the reference current, setting the steady-state behavior of the input differential stage, are typical for the suggested circuit of IA. A big number of inputs for signal processing of a large number of sensors is possible in IA. The modification of IA with higher fast response in the large signal mode, which is provided due to the application of the input differential stages with the extended range of active work, is suggested.

AbstractThe considerable amount of works on machine operation extension of overload and transport technology equipment of fuel overload is made for Balakovo NPP in 2014-2015. Due to the revising STD (scientific and technical documentation) from the moment of power unit input in operation, the deep analysis of STD, designer and operational documents is carried out. Absence of the approved techniques of operation extension for this type of the equipment is revealed. The document analysis showed that machines are constructed with the considerable inventory of seismic stability and satisfy with STD. The research task of detection of the main faulting factors and residual resource assessment with their account for machine mechanical part of overload and transport technology equipment of fuel overload is set. Programs of survey on each machine are made individually and agreed with developers and operators of overload machines (and the set of СOM (current operating maintenance) differing on power units). Search of faulting factors is carried out using methods of visual and non-destructive testing. Survey revealed absence of degradation of metal that allowed to discard the majority of factors as not limiting the overload machines and СOM resource. For an assessment of a residual resource main ones as cyclic loading is selected. A bridge metalwork are selected to be nonrestorable elements for an assessment of a resource . The analysis of cyclic durability allowed to justify period of extension of operation, equal originally to assigned – 30 years. Need for development of the leading document regulating extension of operation period of mechanical part of overload machines and transport technology equipment for overload of PWR-1000 fuel is formulated following the results of operation.
