  • Promising Technology for Reprocessing Complex Uranium Ores from the Elkon
    • Authors: K. M. Smirnov; T. V. Molchanova; A. V. Anan’ev; I. D. Akimova; E. V. Ovcharenko; O. K. Krylova
      Abstract: The results of research on reprocessing of complex uranium ores from the Elkon deposit with recovery of uranium, gold, silver, and vanadium by methods of radiometric sorting, combining of autoclave and atmospheric leaching of ore followed by sorption and extraction recovery of valuable components, are presented. The capacity was 90 mg/g in sorption of uranium on strongly basic anionite and the uranium concentration ≤0.003 g/dm3 in sorption filtrates. The choice of eluent is determined by the formulation of the problem of obtaining the finished uranium product of the requisite form and quality. A fundamentally new composition of the extracting agent is proposed for direct extraction of uranium from nitrate-containing solutions. An iron-vanadium concentrate with vanadium and iron content 2.58 and 22.8%, respectively, suitable for subsequent reprocessing, was obtained. The anionite PuroGold S-992 is recommended for recovery of gold and silver. The gold and silver concentrations in the commercial desorbate were 270 and 380 mg/dm3, respectively; a gold-containing concentrate was obtained.

  • Nature and Formation Mechanism of γ-Induced Color Centers with Optical
           Absorption Band 665 nm in KS-4V and KI Quartz Glasses
    • Authors: A. Kh. Islamov; E. M. Ibragimova; B. S. Faizullaev; I. A. Khaiitboev; I. A. Khaiitov
      Abstract: The aim of the experiment was to elucidate the formation mechanism of color centers with optical absorption band in the region 660–680 nm, which are induced in KS-4V and KI quartz glasses under irradiation by 60Co γ-rays at dose rate 2.5 Gy/sec and temperature 77, 273, and 310 K in the dose range 30–105 Gy. The 665 nm band is induced efficiently in KI samples, which contain more metallic impurities (<10 ppm). It is shown that the 665 nm band induced in KS-4V after soaking at 300 K for 40 min diminishes by approximately 30% and almost vanishes after 3 h; it is thermally stable at <300 K and is completely annealed at ≥323 K. The accumulation kinetics of color centers of the 665 nm band in KS-4V at >4·102 Gy is caused by rupture of the M+O–Si≡ bond near aluminum ≡Al3+. In contrast to KS-4 and KI glasses, KU-1 glass is recommended for small windows in the ITR reactor for the visible part of the spectrum.

  • Special Radwaste Management Prospects
    • Authors: I. I. Linge; M. V. Vedernikova; M. N. Savkin; A. A. Samoilov
      Abstract: The initial registration brought to light the characteristics and disposition of wastes that should be disposed of on-site (special radioactive wastes). The criteria for validating the classification of radwastes as special are presented. The established criteria for the origin of wastes and the location of an object and its sanitaryprotective zone do not permit classifying the radwastes of certain large objects as special even though their removal is unjustified both in terms of dose loads and the risk of potential radiation as well as in terms of financial cost. Criteria are proposed for storage sites for special radwastes for inclusion in the developed regulatory documents, regulating their safe operation and transfer to accommodation and storage sites.

  • Vibratory Processes in Vessel Steel Damage Kinetics in Nuclear Reactors
    • Authors: E. A. Krasikov; V. A. Nikolaenko
      Abstract: The possible reasons for nonstandard embrittlement and significant variance of the experimental data in the study of the impact of neutron irradiation on the properties of reactor vessel materials are analyzed. The authors assume on the basis of experimental data and analysis of foreign research that the fluence dependence of the degree of radiation embrittlement can be of nonmonotonic as well as cyclic. The observation of vibratory processes in the embrittlement kinetics of vessel steel attests periodic transformation of structure and change in the properties of the metal. It is expected that the defect structure formed as a result of neutron bombardment undergoes transformation once or periodically in the direction of losses as well as restoration of the initial properties. The mentioned data shape the search for methods of regulating the radiation resistance of materials.

    • Authors: E. V. Bespala; V. F. Myshkin; A. O. Pavlyuk; I. Yu. Novoselov
      Abstract: The aim of the present work is mathematical modeling of the heat and mass transfer of 137Cs under the action of low-temperature equilibrium plasma flow on sections of graphite contaminated by radionuclides. The methods of investigation are calculation of the temperature and mass rate of evaporation of radiocesium by solving a system of quasi-homogeneous nonstationary heat conduction equations with boundary conditions of the first and third kind, which take account of mass transfer, by means of finite-difference elements using the ANSYS package.

  • Conjugacy Analysis of the Finite-Difference Equations of the Method of
           Characteristics on the Basis of a Linear-Algebraic Formulation
    • Authors: I. R. Suslov; I. V. Tormyshev
      Abstract: A linear-algebraic form of the equations of the method of characteristics, which is used to approximate the neutron transport equation, is obtained. It is shown on the basis of the obtained linear-algebraic form that the discrete form of the conjugate equation differs from the algebraically discrete problem constructed by linear-algebraic transformations of the discrete form of the normal problem. The reason for the discrepancy lies in the approximation of the volumes of the spatial cells in covering the working region by a network of characteristics. It is shown by means of test calculations that when the network of characteristics is refined the solution of the conjugate transport equation converges to the solution of the algebraically conjugate problem.

      Abstract: The key experimental and computational studies of the emission of long-lived radioactive fission products and actinides from uranium dioxide irradiated in BN-600 into sodium and the gas phase in the range 150–800°C, performed on the experimental bench at the Leipunskii Institute of Physics and Power Engineering, are presented. The results of measurements of the properties of aerosols of certain radioactive fission products formed upon heating of irradiated nuclear fuel in sodium are presented. The experimental results are of interest for evaluating the radiation impact of reactor facilities on workers and the public during beyond design basis accidents.

  • Efficiency and Risk of Investments in Nuclear Power
    • Authors: V. V. Kharitonov; A. V. Bokov; N. N. Kosterin
      Abstract: It is shown that together with the reduced cost of electricity it is also necessary to examine other efficiency criteria for investments in NPP – the internal profitability norm and the discounted payback time of investments – and their impact on the primary profitability criterion of an NPP project – the pure discounted income. The analytical interconnection of the pure discounted income, internal profitability norm of a project, and the discounted payback time of investments, which is obtained using an exponential discounting function for the expected cash flows, is shown. The requirements of the engineering and economic parameters of NPP that make NPP competitive on the world market are formulated from an analysis of the interrelation of investment efficiency criteria. The NPP investment risk evaluated by the Monte Carlo method with prescribed uncertainty of prediction of cash flows during construction and operation of NPP is presented.

  • Neutron Flux Density Effect on Vessel Steel Embrittlement
    • Authors: V. A. Nikolaenko; E. A. Krasikov
      Abstract: The effect of the neutron flux density on the embrittlement of the reactor vessel materials is analyzed in an investigation of the impact of neutron irradiation on their properties. The evaluation of the dependence of radiation embrittlement of the vessel steel on the neutron flux density is made to a fi rst approximation for conventional virtual material by averaging the radiation embrittlement coefficient, taking account of the chemical composition, AF = 800(P + 0.07Cu). The actual radiation embrittlement coefficient was determined experimentally on the basis of the normative dependence ΔTF = AF(F·10–18)1/3. It was found as a result that the dependence of the radiation embrittlement coefficient of virtual steel on the neutron flux density has the form AF = 17.8 + 9.5/φ, where φ is the neutron flux density in the units 1011 sec–1·cm–2. As the neutron irradiation intensity decreases, embrittlement increases; the highest sensitivity to the neutron flux density is observed in the range (0.1–1)·1011 sec–1·cm–2. This dependence makes it possible to evaluate the impact of the intensity of neutron irradiation of vessel steel on embrittlement.

  • Molten Salt Reactor for 99 Mo Production
    • Authors: A. L. Tataurov; O. S. Feinberg
      Abstract: 99Mo production in a molten salt reactor with fuel salt based on metal fl uorides (LiF–BeF2–UF4) is examined. The proposed method of production is based on a particularity of the behavior of gaseous fission products in salt melts. Molybdenum, together with some other metals, does not form stable compounds in fluoride melt. At least 50% of fragment molybdenum in a molten salt nuclear-physical facility will be in a gas-aerosol phase above the surface of the molten salt. Neutron-physical and thermohydraulic calculations were performed taking into account the specific features of a molten salt reactor. The optimal configuration of the reactor, the materials used, the fuel salt composition, and the fuel cycle are described.

  • Enrichment of Regenerated Uranium in a Gas Centrifuge Cascade with
           Simultaneous Dilution of 232,236 U by Waste and Low-Enrichment Uranium
    • Authors: A. Yu. Smirnov; G. A Sulaberidze; A. A. Dudnikov; V. A. Nevinitsa
      Abstract: It is shown that regenerated uranium can be enriched in a gas centrifuge cascade with three feed streams (waste uranium, low-enrichment uranium, regenerated uranium) and simultaneous dilution of the isotopes 232,234,236U. Computational experiments were performed for different 235U content in the low-enrichment feed. The chosen combination of diluents makes it possible simultaneously to lower the separative work expenditure and reduce the consumption of native raw material with respect to not only previously used multi-stream cascades but also a standard cascade for enrichment of native uranium.

  • Particulars of Uranium-Plutonium Nitride Fuel Swelling During
           Low-Temperature Irradiation in Fast Reactor to Burnup 5.5% h.a.
    • Authors: A. V. Belyaeva; I. F. Gil’mutdinov; I. Yu. Zhemkov; F. N. Kryukov; S. V. Kuz’min; O. N. Nikitin; Yu. A. Ivanov; Y. A. Kostyukov
      Abstract: Electron-microscopic and electron-probe x-ray spectral studies of nitride fuel microstructure in thin sections and fractures of pellets in correlation with the xenon distribution were conducted in order to obtain data on the particulars of porosity formation and mechanisms of swelling of nitride fuel during low-temperature irradiation. The results attest indications of restructuring of nitride fuel irradiated to burn up 5.5% h.a. at temperature below 880°C. The formation of some grain structure in the restructuring process, accompanied by emission of gaseous fission products from the fuel matrix into pores, affects the swelling rate of uranium-plutonium nitride fuel.

  • Computational and Experimental Analysis of Pu, Np, Am, Cm Reaction Rates
           on BFS Critical Benches
    • Authors: O. N. Andrianova; V. A. Dulin; I. V. Mikhailova; A. A. Andrianov
      Abstract: A computational and experimental analysis is presented of a systematized and reconsidered series of experimental studies of the absolute fission rate of Pu, Np, Am, and Cm performed on the critical benches BFS-1, -2 in the period from 1990 to 2013. Twenty seven critical configurations are examined – models of the reactor core with different types of fuel and coolant. Previously obtained experimental values are re-examined according to more accurate methods of processing the results taking account of residual deformations of chambers and with the introduction of corrections for the efficiency of fragment detection (acts of fission in chambers). The computational models of the assemblies are supplemented by models for evaluating the ratio of the fission rates using non-analogical modeling algorithms. The matched set of experimental data and computational models can be used in diverse applied and fundamental problems.

      Abstract: A method is proposed for determining the elastic modulus of a material from the results of bending tests performed on a prismatic sample using simultaneously the method of digital correlation of images for precise measurement of the displacements of points in the sample. This procedure was tested in three-point bending of steel and graphite samples. The effect of the ratio of the distance between the supports to the height of the cross-section of the sample on the reliability of the determined elastic modulus of the material is evaluated. The values obtained for the modulus of elasticity of steel and graphite agree with the characteristic values for the investigated materials when the ratio of the distance between the supports to the height of the cross-section of the sample is greater than 7.

  • Model Studies of Coolant Flow Hydrodynamics in VVER-1000 In-Reactor
           Pressure Channel
    • Authors: V. G. Krapivtsev
      Abstract: The results of the development, construction, and testing of a small-scale model of a pressure channel of coolant motion inside the VVER-1000 vessel from the entry connections to the coolant flow entry into the core are presented. A hydrodynamic bench, a model of in-reactor pressure channel in the VVER-1000, and methods for studying the coolant flow hydrodynamics in the channel model are described. The results of experimental studies and a comparative analysis of the coolant flow velocity distribution along the annular pressure channel from the entry into the channel through the pressure connections to the entry section in the elliptical bottom of the cavity of the model are presented. The experimental results obtained for different flow regimes of the coolant through the pressure connections are presented.

  • Effect of Operating Parameters on RBMK-1000 Fuel-Element Cladding
    • Authors: A. V. Sukhikh; S. S. Sagalov; S. V. Pavlov
      Abstract: The results of research on the corrosion state of the fuel elements of sixteen RBMK-1000 fuel assemblies operating at the Leningrad NPP to burnup 6.1–35.7 MW·days/kg are presented. The dependences of the oxide thickness on the outer surface of cladding on the operating time, fuel burnup, and average power release of FA are presented. It is determined that increasing the power output from 0.9 up to 2.1 MW approximately halves the oxidation rate on the sections between the spacing lattices. For close FA operating parameters, larger oxide thickness was recorded on sections of fuel elements beneath the steel spacing lattices than beneath the zirconium lattices. It is shown that in terms of the conditions for its manifestation and external indicators the additional oxidation arising beneath the steel lattices has the characteristic features of shadow corrosion.
