  • Multifunctional Backup for NPP Internal Needs
    • Authors: R. Z. Aminov; A. N. Egorov; V. E. Yurin; V. N. Bessonov
      Pages: 327 - 333
      Abstract: The multifunctional backup power system for the internal needs of nuclear power plants uses an added steam turbine. This approach makes it possible to increase the power capacity of NPP with water cooled reactors and at the same time maintain high safety and reliability. The reactor cools down in 72 h in the event of an accident with total blackout of NPP. The significant results of multifunctional backup are: positive economic impact, pay back of the added capital investments in the safety system, and higher technical and economic efficiency, safety, and competitiveness of NPP.

  • Determination of the Heat-Exchange Characteristics of Low-Pressure
           Heat-Exchangers for Lead and Lead-Bismuth Cooled Loops
    • Authors: A. V. Beznosov; A. S. Chernysh; A. D. Zudin; T. A. Bokova; E. G. Novinskii
      Pages: 334 - 338
      Abstract: Heat removal during transient processes in nuclear power installations and bench loops cooled by lead and lead-bismuth coolant is studied. It is shown that low-pressure heat-exchange equipment is effective. The studies were conducted in a non-isothermal loop with circulating of lead coolant at 450–500°C, average speed in the narrow section of the gap in longitudinal flow over the heat-exchange surface 0.1–1.05 m/sec, Peclet number 300–3300, and the oxygen thermodynamic activity in lead 1–10–3. The processes occurring in a non-isothermal liquid-metal loop with an experimental heat-exchange section model the dependence of the heat-exchange characteristics on impurity mass transfer in the loop.

  • Laser Plasma Methods for Improving the Corrosion Resistance of EP-823
           Steel Fuel-Element Cladding at 650–720°C
    • Authors: V. M. Borisov; V. N. Trofimov; V. A. Kuz’menko; A. Yu. Sapozhkov; V. B. Mikhailov; A. A. Yakushkin; V. E. Cherkovets
      Pages: 344 - 349
      Abstract: The existing excimer lasers with pulse durations in the nanosecond range and high pulse and average power afford a unique possibility of influencing the surface of materials and developing new, efficient technologies. It is shown in this article that surface treatment with a periodic-pulse UV laser cleans surfaces by removing oxides, reduces roughness, and increases hardness. Different variants of pulsed laser deposition of aluminum and Al2O3 are used to form protective, composite, cermet layers that suppress surface corrosion of EP-823 steel fuel-element cladding in lead in contact with air at 650–720°C.

  • Incentives and Prerequisites for Modernizing NPP Radwaste Management
    • Authors: V. A. Vinnitskii; A. F. Nechaev; A. S. Chugunov; V. I. Pereguda; I. V. Ryzhov
      Pages: 350 - 354
      Abstract: It is shown analytically that the introduction of the law “On the Management of Radioactive Waste” and the start of the active phase of the decommissioning of NPP have changed goal-setting in the waste management system and actualized the task of modernizing the system. The necessary conditions for improving the technological platform for managing radioactive waste at NPP (R&D status, experience in using in practice the advances made in science, commercial accessibility of the required materials and technical means) have mostly been formulated. Modernization of the waste management system, as a rule, does not require radical revisions of the design solutions or high material costs.

  • Experimental Investigation of Ion Sources of Gas-Filled Neutron Tubes
    • Authors: S. P. Maslennikov; E. Ya. Shkol’nikov
      Pages: 360 - 364
      Abstract: The results of experimental studies of discharge generation regimes in ion sources of gas-filled neutron tubes are presented. The objects of investigation are neutron tubes developed at the Dukhov All-Russia Research Institute of Automatics (VNIIA) for portable pulsed neutron generators. The experiments showed that the conditions for igniting a discharge depend on the pulse-periodic powering system of the ion source and the conditions for heating the gas generator of the neutron tubes. The obtained data show that the efficiency and stability of gas-filled neutron tubes can be increased by optimizing the operating regimes of the powering systems and creating the appropriate ignition conditions for a discharge.

  • Uncooled CdTe and CdZnTe Based Detectors for γ-Radiation Spectrometry
    • Authors: I. M. Gazizov; A. A. Smirnov; V. G. Fedorkov; Yu. P. Kharitonov; V. S. Khrunov; V. M. Zaletin
      Pages: 365 - 370
      Abstract: The results of a study of the electrophysical characteristics of the detector single crystals CdZnTe and CdTe obtained from the best domestic (Institute of Rare Metal Industry, Giredmet) and foreign (Acrorad (Japan) and Redlen (Canada)) producers are presented. The values of (μτ)e in Redlen CdZnTe were 3·10–3–2·10–2 cm2/V. It is shown that the transport characteristics μτ of nonequilibrium charge carriers in domestic materials is 3–30 times lower than in the foreign samples. The spectrometric characteristics of the fabricated detectors were studied in the γ-ray energy range 30–662 keV using uncollimated γ-ray sources 133Ba, 241Am, 57Co, and 137Cs. The measured spectra of the amplitude distribution of the pulses from these sources are presented. The best energy resolution for quasi-hemispherical CdZnTe detectors in terms of the energy 662 keV 137Cs was 1.7%. The results of these investigations are of interest for monitoring nuclear materials using compact devices with high energy resolution that do not require cooling.

  • Method of Routine Monitoring of Fuel-Element Cladding Tightness During
           Icebreaker Core Removal
    • Authors: M. M. Kashka; A. N. Pastukhov; O. B. Samoilov; B. I. Kolomiets; S. P. Dovbush
      Pages: 371 - 376
      Abstract: The tightness of fuel-element cladding is monitored in order to identify fuel assemblies where depressurization has occurred in the course of operation. The condition of the fuel elements in the fuel assemblies of icebreaker cores is determined during refueling of the reactor immediately after a spent assembly is loaded into a dry cell of the storage facility cover in the floating technical service facility by extracting an air sample from its active part into a standard radiation-monitoring measurement system. This method of monitoring cladding tightness does not disrupt the refueling of icebreaker reactors or the refueling cycle time and allows routine evaluation of the condition of the core for representative extraction of spent fuel assemblies for materials studies.

      Pages: 377 - 382
      Abstract: The results of work on dismantling the graphite masonry and reactor structures of the RFT research reactor at the National Research Center Kurchatov Institute are presented. Remote-controlled technology and remote-sensing measurements of contamination levels were used to perform the operations of removing radioactive structures. Such methods have significantly reduced the impact of the radiation on the workers, the general public living in nearby urban areas, and the environment. The measurements of the dose rate in the masonry channels are presented and the total 137Cs activity in the graphite is determined.

  • Radioactivity Category Determination for Radiation-Protection Concrete in
           Nuclear Facilities Undergoing Decommissioning
    • Authors: B. K. Bylkin; A. N. Kozhevnikov; I. A. Engovatov; D. K. Sinyushin
      Pages: 383 - 387
      Abstract: The classification used during the decommissioning of nuclear installations for the activated materials of radiation protection made of concrete is validated. It is shown that in the decommissioning of nuclear installations the category of activated wastes that are formed, including owing to the large and sometimes determining contribution of 3H in the total induced activity of the concrete with decay times up to 100 years, can be interpreted loosely. The requirements of handling tritium-containing wastes have not been developed.

  • Production of Uranium Hexafluoride with Low 234 U Content in a Cascade
           with Intermediate Product
    • Authors: V. A. Palkin
      Abstract: A scheme is proposed for purifying native uranium hexafluoride in a cascade with one feed stream, two product streams, and one waste stream. The cascade is reckoned as quasi-ideal with adjustments of the obtained 235U concentration for the prescribed content in the external streams. A product with native 235U concentration and low 234U concentration is produced in the intermediate product stream of the cascade. Low-enrichment uranium hexafluoride intended for fabricating nuclear fuel is obtained in the main product stream. A high-quality diluent for high-enrichment uranium or low-enrichment uranium hexafluoride with 234U content less than the ASTM C 996–10 limit norm by a factor of 1.5–2.5 can be produced from the intermediate product.

  • Lutetium and Ytterbium Separation by Ion-Exchange Chromatography
    • Authors: V. D. Kosynkin; T. V. Molchanova; E. V. Zharova
      Abstract: The results of separation the heavy rare-earth elements pair lutetium–ytterbium by ion-exchange chromatography are presented. The technological properties of modern absorbers of strong-sulfuric-acid cationites Purolite C160 and Cybber KX 100 are analyzed. The conditions for extracting lutetium with determination of the main factors – complex-forming substance, conditions of utilization, application of different moderators, elution rate, specific load, and others – are studied. It is shown that lutetium–ytterbium separation with production of fractions containing ≥99.9% Lu with concentration 1 g/liter and Yb concentration ≤0.5 mg/liter is possible in principle. A fraction with the maximum lutetium concentration 3.6–3.7 g/liter and ytterbium concentration 0.3–0.37 g/liter, corresponding to lutetium content 91–92%, was separated.

  • Experimental Validation of the Technical Characteristics of a
           Steam-Generator Cassette in the RITM-200 Reactor
    • Authors: A. M. Bakhmet’ev; O. A. Bykh; D. V. Shchekin; O. V. Makarov; M. A. Kamnev; M. A. Antonenkov
      Abstract: A high-efficiency once-through steam generator is used in the RITM-200 reactor for the universal nuclear icebreaker. The new design necessitated experimental validation of the technical characteristics of the steam generator taking into account the integral arrangement of the steam-generating block. To this end a model of the steam-generator cassette was developed and tested at OKBM Afrikantov. The experimental studies of the model of the steam-generator cassette confirmed the heat-engineering and hydrodynamic design characteristics of the steam generator in the RITM-200 reactor.

  • Modeling of the Thermodynamic Interaction of Beryllium Minerals with
           Different Opening Agents
    • Authors: V. Yu. Kol’tsov; T. B. Yudina; A. A. Zakharov; A. A. Semenov; A. V. Lizunov; A. V. Demin
      Abstract: Modeling of the thermodynamic interaction of beryllium minerals with different opening agents is performed in order to validate the proposed methods of opening beryllium orr at the Ermakovskoe deposit and the structural design of technological equipment blocks. It is found that when beryllium minerals interact with sulfuric acid and alkali the following stability sequences of the minerals are observed: bertrandite–phenakite–beryl with acid and the reverse sequence with alkali. In the case of alkali, the opening of the composition of the reaction products depends on the alkali consumption.

It consists in using polymer matrices made from several interpenetrating low-linkage polymer networks, which are obtained by repeated polymerization of a mixture of mono- and divinyl monomers, solvating the primary copolymer. Using this method, inter-reticular anionites for uranium sorption were synthesized by the means of double copolymerization of styrene and divinyl benzene followed by chloromethylation of the obtained matrix and amination of the chloromethylated copolymer by pyridine. It is shown that in terms of the uranium sorption capacity and kinetic characteristics inter-reticular anionites surpass the best foreign-made resins by factors of 1.3–1.8.

  • Comparison and Analysis of Residual Heat Removal Systems of Reactors in
           Station Blackout Accidents
    • Authors: R. Z. Aminov; A. N. Egorov
      Abstract: A comparative analysis is performed of emergency cool-down systems of water-cooled reactors, using passive heat-removal systems. The use of such a system reduces the likelihood of serious accidents with core damage at NPP but the capital investment and associated operating costs are higher. Auxiliary expenditures on maintaining this system in a standby mode are also required. A scheme combining active and passive cool-down systems is proposed owing to the rejection of air heat-exchangers-condensers of the passive heat-removal system and the installation of an auxiliary low-capacity steam turbogenerator is proposed. A comparative technical-economic analysis of the proposed combined cool-down system and an air passive heat-removal system is performed. The calculations show that at comparable safety levels such a system makes it possible to reduce capital and total operating expenses for NPP located in all climatic belts.

  • Laser Beam Transmission by Inorganic Liquid Activated by Neodymium and
           Uranyl in Pulsed Excitation by Uranium Fission Fragments
    • Authors: P. P. D’yachenko; P. A. Kulikov; E. A. Seregina; A. A. Seregin; G. V. Tikhonov
      Abstract: The transmission of 1.054 μm probing laser radiation by laser liquid \( {\mathrm{POCl}}_{3^{\hbox{--} }}{{\mathrm{SnCl}}_{4^{\hbox{--}}}}^{235}{\mathrm{UO}}_2^{2+}\hbox{--} {\mathrm{Nd}}^{3+} \) excited by uranium fission fragments was measured. It is shown that for liquid pressure 10.1 MPa the transmission of the liquid does not exceed 1. It is found that the transmission of the liquid in the active element with aperture 25 mm is approximately 4 times lower than in an element with aperture 10 mm. A qualitative explanation of the observed effect is proposed on the basis of the assumption that light was scattered by radial acoustic density waves in the liquid. This effect can serve as one of the primary reasons for the absence of lasing during nuclear pumping of the liquid under discussion. Methods of reducing the influence of this effect are examined.

  • Investigation of Thermal and Epithermal Neutron Flux Distributions in
           Universal Nuclear Icebreaker Fuel Assemblies
    • Authors: O. B. Samoilov; V. I. Alekseev; V. Yu. Galitskikh; A. V. Belin; A. N. Zaglyadnov; V. V. Samusenkov; S. G. Ust’yantsev
      Abstract: The results of experimental investigations of the spatial and energy distributions of the thermal and epithermal neutrons in a cassette fuel assembly, similar in design to that developed for the RITM-200 reactor core in the universal nuclear icebreaker, are presented. The measurements were performed using activation detectors with the isotopes 63Cu, 55Mn, and 197Au. It is shown that the structural nonuniformities of the fuel assembly (central water cavity, reactivity compensation system absorbing rod, strongly screened rods with consumable absorber) create significant thermal neutron flux nonuniformity over the cross-section of a fuel assembly. The flux distribution of epithermal neutrons with energy >0.4 eV is almost uniform. The experimental data are supported by calculations.

  • Concentration Dependence of the Rate of Catalytic Isotopic Exchange of
           Hydrogen with Water Vapor on the Catalyst RKhTU-3SM
    • Authors: V. A. Tkachenko; A. V. Ovcharov; M. B. Rozenkevich
      Abstract: One method of separating hydrogen isotopes is chemical isotopic exchange of hydrogen with liquid water, combined with electrolysis of water. At present, different mathematical models are used to calculate the characteristics of newly developed setups. They all have the problem of inadequate data on the characteristics of the chemical isotopic exchange process occurring at medium and high deuterium concentrations. The present work is devoted to investigating one stage of chemical isotopic exchange – catalytic isotopic exchange between hydrogen and water vapor at high deuterium concentrations in application to the catalyst RKhTU-3SM. It is shown that the experimental rate constant of isotopic exchange for the pair protium – deuterium increases by almost a factor of two, while for exchange with tritium increasing the deuterium concentration from 5 to 95% does not change the experimentally observed rate constant to within the measurement error.
