Publication Hydride-dehydride fine zirconium powders for pyrotechnics(2020) Amelichkin I. V.; Knyazeva E. M.; Medvedev R.; Muslimova A. V.; Nefedov. R. A.; Orlov, V. V.; Sachkov, V. I.; Sachkova, A. S.; Zhukov, I. A.; Муслимова (Muslimova, A. V), Александра Валерьевна; Кафедра «Химия и технология материалов современной энергетики» (ХиТМСЭ)In this paper, the possibility of obtaining fine zirconium powders by the hydrogenation-dehydrogenation method is studied. The main parameters of the technological process that allow obtaining fine zirconium powders for pyrotechnics are determined. Hydrogenation and dehydrogenation of the samples are carried out in a rotating quartz tube placed in a furnace at temperatures of 380° C and 850° C, respectively. Zirconium hydride is milled using tungsten carbide balls to eliminate the presence of impurities. Thus it is possible to obtain a fine zirconium powder with a number-average particle size of 4.527 ± 2.650 μm and a specific surface area of 0.231 m2/g from the initial electrolytic zirconium powder with a number-average particle size of 220 μm and a specific surface area < 0.1 m2/g. The allowed relative error of measuring the specific surface area is ± 5%. Hence it is possible to reduce the particle size of zirconium powder by 54.6 times without changing the composition.Publication Sustainable University Development: Concepts, Initiatives, Results(2020) Nekhoda, E.

V.; Bochkareva, A. V.; Nadezhkin, M. V.; Zuev, L. B.; Шляхова (Shlyakhova, G. V.), Галина Витальевна; Кафедра «Машины и аппараты химических и атомных производств» (МАХАП)© 2020 American Institute of Physics Inc.. All rights reserved.The experimental results of structure analysis, such as phase composition, grain size, strength and hardness of elinvar Ni-SPAN-C alloy 902 after different modes of heat treatment (quenching and ageing for stress relaxation) are presented in this study. It is made possible to obtain improved physical and mechanical properties than those acquired by conventional heat treatment. Heat treatment mode was selected that allowed to obtaining higher physical and mechanical properties of elinvar alloy compared to standard technology. It was shown that the improvement of alloy structure during thermal treatment is due to thermal stresses, as well as formation and dissolution of intermetallides.Publication Study of deformation relief of polycrystalline nickel by atomic force microscopy(AIP Publishing, 2020) Shlyakhova, G. V.; Nadezhkin, M. V.; Barannikova, S. A.; Zuev, L. B.; Шляхова (Shlyakhova, G. V.), Галина Витальевна; Кафедра «Машины и аппараты химических и атомных производств» (МАХАП)This work reports the morphology and evolution of deformation relief of polycrystalline nickel. The morphological peculiarities of the relief are investigated using atomic force microscopy. The material fragmentation is shown to be presented by shear strain domains. The main structural elements of the deformation relief are the packs of shear traces and macrobands. The strain (taking into account the individual structural elements of the relief through the sample) is found to be qualitatively equal at the different scales, exhibiting the quasiperiodic behavior. The shear traces with increase in strain are found to evolve into macrobands. In turn, the strain-induced macrobands are composed of the individual shear levels and possess a quasiperiodic profile.Publication Palladium and Rhodium as Possible Catalysts for Nuclear Reactions(2020) Khandorin, G.

D.; Istomin, A. D.; Bugrina, V. S.; Popova, K. Ye.; Истомина (Istomina, N. Yu.), Надежда Юрьевна; Носков (Noskov, M. D.), Михаил Дмитриевич; Истомин (Istomin. A. D.), Андрей Дмитриевич; Кафедра «Физика» (Ф)© 2020 Obninsk Institute for Nuclear Power Engineering, National Research Nuclear University 'MEPhI'. All rights reserved.The use of geoinformation and expert simulation systems to assess the environmental effects from operation of nuclear power installations is discussed. The structure and the functions of the ARIA geoinformation and expert simulation software package are described. ARIA features functional capabilities for building and visualizing digital models of the locality, hazardous installations, and recipient facilities, simulating and visualizing the radiation situation, and analyzing the radiation situation in terms of the activity and dose rate levels for recipient facilities of various geometries. The system makes it possible to calculate spatial distributions of the radionuclide specific activity, the dose and the dose rate as defined by the external and internal pathways for the ionizing radiation impacts. The paper presents the results of using the ARIA software package to calculate the radiation situation with the entry of radionuclides into the surface air layer during normal and emergency operating modes of nuclear power installations. In the former case, the radiation situation was calculated for the Kalinin NPP deployment area. In the latter case, the consequences from a series of short-term emergency releases in the wake of the Fukushima Daiichi accident in Japan in 2011 were assessed. The contribution of long- and short-lived radionuclides to the formation of the radiation background in the event of an emergency release and during normal NPP operation is discussed. Inhalation dose is the most important factor defining the dose rates for the personnel and the public at the early accident stage. That at the later accident stage, both during an accident and during normal NPP operation, is the dose caused by the radiation from the long-lived radionuclides in the surface soil layer. It has been shown that the individual equivalent dose in the Kalinin NPP deployment area is four orders of magnitude as low as the annual dose threshold value set by the radiation safety standards.Publication Experience of implementation in NRNU MEPhI of the education program focused on training of specialists for "proryv" project(NRNU MEPhI, Moscow; STI NRNU MEPhI, Seversk, 2020) Karpov, S.

Mogilnitski to the development of the Tomsk historiographical school (to the 90th anniversary of B. G. Mogilnitski)(2020) Kirsanova, E. S.; Кирсанова (Kirsanova, E. S.), Екатерина Семеновна; Кафедра «Гуманитарные и социальные науки» (ГиСН)The appeal to the work of the scientist famous by his works on historiography and methodology of the history is relevant for several circumstances. It is not limited only by the desire to pay tribute to the memory of the teacher in connection with the anniversary date. In addition to this important reason, there is also a need to emphasize his contribution to the development of the Tomsk Historiographical School, the foundations of which were laid by the B.G. Mogilnitski's teacher A.I. Danilov, about which Boris Georgievich himself wrote repeatedly. At the same time, the rethinking of Soviet historiographical science, taking place in modern Russian historiography and often expressed in its refusal in the status of science, requires a concrete analysis of the works of outstanding Russian historians and to sift out ashes from cinders, rather than bare denial. The article considers the works of the early period of the creativity of Boris Mogilnitski, late 60s - 70s of the 20th century, among which a special place is taken by the monograph, the final study devoted to the national historiography of the 19th - early 20th century and presented by the names of D. M. Petrushevsky, A.N. Savin, I.D. Lucitsky, M.M. Kovalevsky, N.I. Kareev, P.G. Vinogradov, R.Y. Vipper and V.K. Piskorsky. This period of scientific activity of Mogilnitski can also be considered the years of the rise of the Tomsk Historiographic School. Based on the analysis carried out, the author of the article comes to the following conclusions such as: 1. Certain scale of a research. 2. It is noted that for the first time in the Russian historiographic science Mogilnitski made a conscious attempt to combine and apply in the analysis of historical thought three main approaches - the structural, genetic and functional approaches. The systemicity of the analysis allowed the scientist to combine the group of investigated historians into a single "socio-economic direction". 3. It is also worth noting the author's conclusion about the influence of historians on the production of ideology, while his contemporaries researchers insisted on the influence of ideological attitudes on the creativity of historians. The principles of the scientific approach implemented by Mogilnitski in research were instilled in students and postgraduate students in his pedagogical practice, where regular methodological seminars took a special place. On the basis of the above, it can be argued that today, despite the Marxist paradigm within which the study was carried out, this work can be considered as a model of theoretical historiographic research. Thanks to which researchers already in the early 1970s began to talk about the Tomsk Historiographic School.
