  • Infrastructure Objects of the Nuclear Fleet as Sources of Radioactive
           Contamination of the Barents Sea: Waste Repository in Guba Andreeva
    • Authors: G. V. Il’in; N. E. Kasatkina; D. V. Moiseev; I. S. Usyagina
      Abstract: The impact of temporary storage sites for radioactive wastes in Guba Andreeva on the environmental conditions in the coastal zone of the Barents Sea after 50 years of operation is evaluated on the basis of general chronological reconstruction of the dynamics of radioactive contamination of the marine environment. The bottom deposits along the seacoast at different distances from the repository were investigated. It was found that the region of constant impact of the repository on the conditions in the marine environment is localized near the perimeter of the sanitary-protective zone. Growth of the specific activity of 137Cs, 90Sr, 238Pu, 239,240Pu is recorded in sediments layers up to the level 16–20 cm. The impact of the emission of radionuclides from the repository site is not perceptible in the seacoast zone (Motovskii Zaliv). The age of the sedimentary layers was determined: it shows that the significant concentration of 137Cs in the deposits in Motovskii Zaliv corresponds to the mid-1960s and 1986 and is associated with atmospheric fallout of radionuclides as a result of the nuclear weapons tests and the accident at the Chernobyl NPP.

  • Vizart Software for Balance Calculations of Material Flows in Closed
           Nuclear Fuel Cycle Technologies
    • Authors: O. V. Shmidt; S. G. Tret’yakova; Yu. A. Evsyukova; I. R. Makeeva; V. G. Dubosarskii; V. Yu. Pugachev; A. A. Rykunova
      Abstract: The VIZART software for computer modeling of production operations in the reprocessing of spent nuclear fuel, fabrication of nuclear fuel, and management of radioactive wastes was developed as part of the work on the complex technology of closed NFC. It makes it possible to develop models of process schemes or individual operations and perform supporting balance calculations of material flows of the prescribed schemes. A functional for calculating the material balance of products in a scheme taking account of the equipment productivity and constructing sequence diagrams of equipment operation was developed. The presented software, unlike most general-chemical simulators, makes it possible to calculate the characteristics of products which are specific for radiochemical processes: the isotopic composition and its variation during reprocessing, radioactivity, and heat release. These characteristics are important for validating the design and structural solutions from the standpoint of nuclear and fire-explosion safety.

  • Effect of Damaging Irradiation on Low-Temperature Embrittlement of Metals
    • Authors: V. M. Chernov; K. A. Moroz
      Abstract: The effect of low-temperature damaging irradiation on the high-temperature embrittlement (cold shortness) in metals was investigated in a previously proposed model. The cold shortness state with possible brittle fracture in metals is not formed in the irradiation process because of the dynamical radiation processes arising.

  • IBR-2M Reactor Power Feedback Parameters Evaluation Using Square
           Reactivity Oscillations
    • Authors: Yu. N. Pepelyshev; A. K. Popov; D. Sumkhuu
      Abstract: The parameters of a mathematical model of power feedback are evaluated on the basis of an analysis of transient power processes arising in the IBR-2M reactor as a result of intentional square oscillations of the reactivity during operation in a self-regulation regime. The power feedback is described by three linear difference equations and represented in the form of three aperiodic elements connected in parallel. Two components play the role of negative and one component positive feedback. The total feedback is negative, i.e., it has a stabilizing effect on the operation of the reactor. The slowest negative component of power feedback is probably due to axial swelling of the fuel as it heats up. Since the power feedback parameters change in the course of operation, their periodically repeated evaluations are one way of securing the operational safety and reliability of the reactor.

  • FAN15 Code Modeling of Electron and Positron Transport
    • Authors: E. N. Savitskaya; A. V. Sannikov
      Abstract: A method of modeling the transport of electrons and positrons with energies 1 keV–10 MeV implemented in the FAN15 code is described. The code takes account of multiple Coulomb scattering, fl uctuations of ionization losses, formation of δ-electrons, and Bremsstrahlung and x-ray photons. The EEDL and EADL evaluated data libraries are used in the calculations of Bremsstrahlung and emission of x-ray photons upon relaxation of ionized atoms. The computational results are compared with the experimental data on the energy, angular, and dose distributions of 0.5–10 MeV electrons in different absorbers.

  • Immobilization of Highly Toxic Beryllium-Containing Wastes in Cement
           Compound Using Polycarboxylate Super-Plasticizers
    • Authors: A. A. Semenov; N. I. Shipunov; A. I. Zhidelev; D. A. Korobeinikov; I. G. Lesina; A. S. Denisov; N. E. Zabirova; S. E. Saifutdinova; A. V. Lizunov; I. B. Kupriyanov; S. P. Saikin; N. V. Filimonova
      Abstract: A technology has been developed for immobilizing highly toxic beryllium-containing wastes in a cement compound using polycarboxylate superplasticizers. Two cement mixture compositions, containing polymer superplasticizer comprised of polycarboxylate with high strength in compression, high frost resistance, water impermeability, and resistance to beryllium leaching were developed. The proposed compositions guarantee confi nement of beryllium for a long period of time.

  • Membrane Electrolysis in Beryllium Hydroxide Production Technology
    • Authors: V. B. Nikolaevskii; M. L. Kotsar’; V. E. Matyasova
      Abstract: Experimental studies of the electrochemical neutralization of an alkaline solution for the production of beryllium hydroxide with simultaneous regeneration of NaOH are expounded. The kinetics is studied and the basic technological parameters are determined – current density, voltage, duration, and specific electricity consumption. The use of MF-4SK instead of MK-40 membranes in the neutralization of alkali in two stages approximately halves the process time. The concentration of the regenerated solution reaches 450 g/dm3, as required for autoclave opening. It is shown that in principle membrane electrolysis can be used for neutralization and parallel regeneration of alkali in reprocessing solutions after autoclave opening of raw material. A technological scheme is proposed for obtaining beryllium hydroxide by membrane electrolysis.

  • Comparative Geological and Mineral-Petrological Analysis of Ore-Bearing
           Rock in Lithium and Beryllium Deposits for Modeling the Behavior of Ore
           Minerals During Processing
    • Authors: V. Yu. Kol’tsov; T. B. Yudina; Yu. V. Azarova; A. A. Semenov; A. V. Lizunov; I. G. Lesina
      Abstract: A comparative analysis of ore-bearing rock in the Zavitinskoe and Ermakovskoe deposits is made. Such an analysis is needed because of the requirements of working with ore-mining concentrates, which model the basic physical and chemical parameters of beryllium-containing concentrates that influence their preparation efficiency and subsequent opening with reagents. It was found that it is possible to develop a general model system for the chemical and physical behavior of lithium and beryllium ore minerals and the bearing rock in the Ermakovskoe and Zavitinskoe deposits. Ore materials in the Zavitinskoe deposit (lithium association) model the physicochemical behavior of beryllium-containing ore minerals in the Ermakovskoe deposit (beryllium association).

  • Analysis of the Effect of the Stress-Strain State of Irradiated
           Zirconium-Alloy Fuel-Element Cladding on Hydride Orientation
    • Authors: G. V. Kulakov; A. V. Vatulin; Yu. V. Konovalov; A. A. Kosaurov; M. M. Peregud; E. A. Korotchenko; V. Yu. Shishin; A. A. Shel’dyakov
      Abstract: The effect of the stress distribution on the hydride distribution in zirconium cladding of fuel elements with dispersion fuel is analyzed. It is shown that reorientation of zirconium hydrides can occur in fuel-element cladding under the action of tensile stresses, which can result in the appearance of radially oriented hydrides and plasticity reduction in the cladding upon cool-down of the fuel elements. The threshold tensile stresses are determined in the cladding in the unirradiated and irradiated states, in which hydride reorientation from tangential to radial occurs.

  • Microdosimetric Interpretation of the Dose and Dose Rate Efficiency
    • Authors: V. A. Sakovich
      Abstract: A model of a hypothetical process resulting in damage to DNA by ionizing radiation, as a result of which a nonlinear dose dependence of carcinogensis can form at dose 10–100 mGy, is examined on the basis of a microdosimetric approach. The model assumes that the primary damage to DNA interacts with short-lived products of irradiation before the DNA is repaired or transformed into a precancerous defect that is transferred to a daughter cell. It is shown that there are grounds for using the ICRP effective dose and dose rate lowering coefficient equal to 2 in the evaluation of the lifetime risk of irradiation with a significant dose and in the validation of criteria for radiation safety on the basis of data on morbidity and mortality in a cohort of Japanese atomic bomb survivors.

  • Environmental Risk of the Radiological Accidents at Chernobyl and
           Fukushima (Japan) NPP
    • Authors: I. I. Kryshev; E. P. Ryazantsev
      Abstract: A comparative analysis of the levels of radioactive contamination of the environment on territories exposed to the accidental emissions from the Chernobyl and Fukushima (Japan) NPP is presented. An integral evaluation of the post-accident radio-ecological conditions based on evaluation of the irradiation dose rate to biota organisms and subsequent environmental risk calculations is presented. It is shown that with the exception of the Red Forest territory near the Chernobyl NPP the highest dose loads on biota in the exclusion zones of both plants are approximately the same taking account of the uncertainty of their evaluations in the first post-accident period. The ecosystems in the exclusion zones remain viable and have retained their species diversity. On most of the radioactive track of the Chernobyl NPP and outside the Fukushima NPP exclusion zone, the radiation risk levels are significantly below environmentally safe values.

  • Increasing Approximate-Solution Accuracy by Using Perturbation Theory
    • Authors: A. N. Kuz’min
      Abstract: Methods based on the use of relations from perturbation theory are proposed for increasing the accuracy of the solutions of equations describing nonstationary processes occurring in reactors. The analysis is limited to the adiabatic approximation and slow variations of the properties of a reactor. Results are presented for the problem of fuel burnup for a two-zone model of a fast reactor where criticality is maintained by varying the concentration of a neutron absorber. The computational aspects of the method are discussed and the prospects for using the method in computational optimization software codes are discussed.

  • BaWF 8 Crystals – Efficient X-Ray Luminophores
    • Authors: I. Nuritdinov; A. B. Uteniyazova; B. T. Atashov
      Abstract: The spectral-kinetic characteristics of cerium- and chromium-doped samples of BaWF8 synthesized by the hydrothermal method were investigated. A luminescence band peaking at 490 nm with half-width 150 nm was found. It is shown that in the terms of the conventional luminophore NaI(Tl) the integral light yield of the x-ray luminescence equals 32% for BaWF8 crystals and 36.5% for BaWF8:2%CrF3. No afterglow of the experimental crystals is observed 20 msec after irradiation stops. Analysis shows that undoped and doped BaWF8 crystals synthesized by the hydrothermal method are promising materials for x-ray tomography.

  • Sodium-Bench Testing of a Cold-Trap Model

      Abstract: Experimental data on the precipitation of an impurity (sodium oxide) in sodium coolant in a model of a cold trap of a fast reactor are obtained using a specially developed technique. The working model included the zones of filtration, spontaneous cooling, and cooled settling tank, which were intended for collecting the settling impurities. The working cavity was cooled by sodium-potassium alloy melt outside its housing. It is shown that there are two local maxima in the distribution of the sodium oxide deposits along the height of the model; these peaks correspond to the initial and final sections of the cooling zone. The model constants of impurity mass transfer in the model of a cold trap are refined experimentally. The calculations performed with the refined model of mass transfer for the standard variant of a cold trap built into the reactor tank showed that the model constants are optimal.

The structural arrangement of the setup and the results of calculations of transient regimes in the BR-1200 reactor are described. A system with such setups included in the core will make it possible to lower the maximum fuel, fuel-element cladding, and coolant temperatures below the design limits, including in the event of accidents with multiple failures, and to completely suppress a fission chain reaction if the efficiency of the system is high enough.

  • Method of Calculating the Temperature Regimes of Fuel Elements in Fuel
           Assemblies Taking Account of Inter-Channel Coolant Mixing and Random
           Deviations of the Parameters
    • Authors: S. S. Gordeev; A. P. Sorokin; B. B. Tikhomirov; A. A. Trufanov; N. A. Denisova
      Abstract: A method of taking account of the maximum temperature of fuel-element cladding and temperature nonuniformity along the perimeter of the fuel elements taking account of interchannel mixing of the coolant in the FA of sodium-cooled fast reactors is described. The calculation of the temperature field using the MIF code with a random distribution of the flow sections of the channels and the energy release of fuel elements using the Monte Carlo method shows that the average maximum temperature of fuel-element cladding lies in the interval determined in the models of tightly packed and maximally open bundles and that the temperature nonuniformity along the perimeter of the fuel elements is higher than in the calculation performed with average parameters of a bundle.

  • FAN15 Software Code for Calculating Low-Energy Photon and Neutron Transfer
           in Arbitrary Media
    • Authors: E. N. Savitskaya; A. V. Sannikov
      Abstract: The FAN15 software for the transfer of low-energy photons and neutrons is described. The constants base for modeling the interaction of the particles with matter is based on modern evaluated data libraries. The computational results obtained with FAN15 show good agreement with experimental and other computational data. This software can be used as a stand-alone code or a low-energy block for the HADRON high-energy hadron transfer code.

  • Contact-Free FA Placement Checking in VVER
    • Authors: S. K. Mankevich; E. P. Orlov
      Abstract: A method of contact-free determination of FA elevations to check FA placement for purposes of better operational safety of VVER-440 and -1000 is proposed. The method includes scanning specially shaped light beams over the flat tops of the assemblies, recording the reflected signal with a TV camera, and processing the information in a computer. The measurement setup developed on the basis of this method can record a difference of 0.1 mm between the elevations of the flat tops to within 1% with admissible dispersion of 1–1.5 mm. The scanning and output of elevation information are accomplished in 10–15 min. The measurement setup to be used in the water medium of the loading zone of a nuclear reactor is implemented using radiation-resistant elements.
