  • Neutron-Physical Model Impact on the Calculation of a Serious Accident
           with Sodium Boiling in a Fast Reactor
    • Authors: Yu. M. Ashurko; A. V. Volkov; K. F. Raskach; N. V. Solomonova
      Pages: 217 - 225
      Abstract: A comparative analysis is made of calculations of a loss-of-coolant accident in a 1500 MW(t) fast reactor. The COREMELT code with different neutron-physical modules RADAR3D and RAKAR2D and the same thermohydraulic module COREMELT are used. The computational results are used as a basis for comparing the self-protection of a reactor with a sodium cavity at the top of the core for the case of a serious accident with coolant boiling. The effect of the diffusion and transport modules of the spatial neutron-physics models on the calculation is analyzed.

  • Measurement of the Power Coefficient of Reactivity of VVR-Ts in a Wide
           Power Range
    • Authors: V. V. Kolesov; D. S. Samokhin; O. Yu. Kochnov
      Pages: 226 - 229
      Abstract: The power coefficient of reactivity of VVR-Ts was previously determined only in the range 10–11 MW. The aim of the present work was to determine the power coefficient of reactivity in the range 1–10 MW. The experiment was performed on a completely depoisoned reactor. The change in the reactivity excess was determined according to the position of the control rods. It was shown experimentally that the power coefficient of reactivity is not constant and is negative for the given power range. Thus, the VVR-Ts reactor can operate safely in different operating regimes.

  • Magnetic Flowmeter for Fast Sodium Reactors
    • Authors: I. D. Vel’t; E. A. D’yakonova; Yu. V. Mikhailova; N. V. Terekhina
      Pages: 243 - 251
      Abstract: A magnetic flowmeter for liquid sodium is described. The inductor in this device consists of an electromagnet generating a pulsed, low-frequency, magnetic field. The use of a pulsed magnetic field made it possible to separate the informative component of the signal from all electromagnetic interference whose time variation is not a multiple of the frequency of the excitation magnetic field. Thus, all interferences at the industrial frequency and the thermo-emf are eliminated. This increases the accuracy of flow rate measurements significantly and makes it possible to reduce the magnetic field in the channel. The power of the inductor does not exceed 0.5 W. There is no need to adjust the zero point, and it is possible to measure low flow rates and the reverse flow. The physical principles of the method of measurement, the design particulars and technical characteristics of the device, and the results of tests are examined.

  • Technology and Facility for Incinerating Irradiated Reactor Graphite
    • Authors: V. A. Kashcheev; O. A. Ustinov; S. A. Yakunin; V. S. Zagumennov; A. O. Pavlyuk; S. G. Kotlyarevskii; E. V. Bespala
      Pages: 252 - 256
      Abstract: The USG-1 facility was developed to incinerate spent reactor graphite. It is equipped with a monitoring and control system; its maximum capacity is 10 kg/h. Trial combustion of a batch of unirradiated graphite was conducted. The tests showed that the units in the facility are serviceable and irradiated reactor graphite can be incinerated directly in an air flow. For a 1.5 kg load of graphite, the burn rate at 900°C was equal to 0.3 kg/h. The burn rate increases with increasing load. The incineration of irradiated graphite bushings of the EI-2 reactor in the USG-1 incinerator was studied at PDC UGR. The completeness of incineration was 95% and the 137Cs catching efficiency was 95%. With modification of the gas purification unit, the USG-1 incinerator can be used to burn irradiated graphite contaminated by traces of nuclear fuel and in monitoring the atmospheric emissions of 14CO2.

  • Mobile Systems for Fluoride Reprocessing of Spent Nuclear Fuel
    • Authors: N. M. Trotsenko; O. G. Lebedev; D. Yu. Chuvilin
      Pages: 257 - 262
      Abstract: Experts at the National Research Center – Kurchatov Institute have proposed compact reprocessing of spent nuclear fuel from the naval fleet as well as NPPs close to the Arctic coast, directly at the site of offloading, on the basis of an innovative, experimentally verified, fluoride-distillation technology. They propose developing a mobile system consisting of a seagoing carrier (vessel with small displacement) or terrestrial carrier (railroad platform) on which is mounted a compact process line consisting of fluorination and purification apparatus as well as auxiliary setups. There are no liquid wastes in the fluoride processes; solid wastes are to be removed, as they are formed, from the mobile system into special sites in waste locations of the Arctic coast for long-term dry storage in concrete containers.

  • Possibilities of Increasing Logging Efficiency with Simultaneous Analysis
           of Neutron and Gamma Fields Formed in Oil Wells
    • Authors: B. Yu. Bogdanovich; K. I. Kozlovskii; A. V. Nesterovich; A. E. Shikanov; A. V. Il’inskii; E. G. Urmanov
      Pages: 271 - 277
      Abstract: The increase in the efficacy of studying well saturation in simultaneous analysis of radiation fields by means of pulsed neutron, activation, and spectrometric logging is examined. It is shown that neutron activation logging can in principle be realized in experimental testing of an operating model of apparatus in producing geophysical objects. Technical solutions using neutron well radiators based on sealed accelerator tubes with a laser source of deuterons and magnetic insulation, as a result of a large neutron yield combined with high pulse stability, as well as a thermally stabilized γ spectrometer, are proposed and validated.

  • Hot Particles and Radionuclide Transport in Water Media
    • Authors: N. L. Kuchin; A. I. Laikin; Yu. A. Platovskikh
      Pages: 278 - 283
      Abstract: The characteristics of hot particles in the ambient environment are presented: activity, propagation, size, and density as well as contribution to the total activity of contaminants, distribution factor, leach rate, and deposition rate. The differences of suspensions, bottom deposits, and hot particles are shown. The equations governing the transport of radionuclides are formulated for systems, consisting of hot particles and suspensions, in water and bottom deposits. The coefficients in the equations are determined and the possibility of radionuclides being removed from bays by tides is taken into account. Solutions are obtained for the transport equations and the average sizes of the activity spots owing to hot particles and ordinary suspensions are determined. The possibility of transport of hot particles over large distances in a river floodplain is examined. The water circulation rate at which hot particles are carried out of flooded objects is determined.

  • 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.

  • Dependence of the Determined Value of the Elastic Modulus of a Material on
           the Ratio of the Distance Between the Supports to the Height of the
           Cross-Section of the Bent Sample
    • Authors: V. Yu. Gol’tsev; A. V. Osintsev; A. S. Plotnikov
      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
           Oxidation
    • 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.

  • Use of Radioactive Beams of 7 Be Nuclei to Study the Wear Resistance of
           Materials
    • Authors: A. A. Ogloblin; V. N. Unezhev; V. I. Novikov; T. Yu. Malamut
      Abstract: This work is devoted to the use of beams of radioactive nuclei for applied purposes – to study the wearresistance of materials used in different industries. The crux of the method is that the radioactive nuclei obtained in the nuclear reactions 1H(7Li, 7Be) and 1H(10B, 7Be) are implanted in the experimental sample. After implantation of the nuclei, the sample undergoes wear tests. The γ-radiation of the implanted nuclei is high-energy; the spectrum is comparatively simple and does not produce appreciable radiation damage in the test samples. The method has been successfully tested in determining the wear-resistance of machine parts and mechanisms.

      Abstract: The results of thermohydraulic code HYDRA-IBRAE/LM/V1 verification on experimental data obtained using the BN-600 reactor in different years are described. The particulars of the computational scheme of the reactor using HYDRA-IBRAE/LM/V1 for modeling the BN-600 operating regime are presented. In preparing the scheme, special attention was devoted to accurate modeling of the reactor cool-down regimes on natural circulation as being most important from the safety validation standpoint. The computational results obtained with the uncertainty of the initial data taken into account are presented for such a cool-down regime.
