  • Sorption Extraction of Uranium from Fluorine-Containing Media During
           Reprocessing of Radiochemical Production Wastes
    • Abstract: Experimental data on the sorption extraction of uranium from fluorine-containing solutions on different types of modern ion-exchange absorbers and structures in order to improve the technological schemes for reprocessing wastes from radiochemical production are presented. The primary technological relations are studied and the optimal indices in static and dynamic regimes of sorption-desorption extraction of uranium from model systems simulating production fluorine-containing solutions are determined. A chelate-forming aminophosphonic cation-exchanger Purolite S950 with uranium capacity up to 20% is recommended. It is shown that uranium concentration in the waste ≤0.003 g/liter can be obtained. It is found that uranium desorption by a 15% solution of sodium carbonate is a highly efficient process with desorption time 10 h and degree of uranium desorption 99.92%.

  • Fracture Toughness of VVER and PWR Uranium-Dioxide Fuel Pellets with
           Different Grain Size
    • Abstract: The results of experimental studies of crack formation and fracture toughness of VVER and PWR uranium dioxide fuel pellets with different grain size are presented for the purpose of making a comparative analysis of their strength properties. It is found that as the grains increase in size their Young’s modulus and the microhardness increase and the fracture toughness decreases. It is determined that for relatively small loads (to 1 kg) the formation of Palmqvist cracks is characteristic for uranium oxide pellets, and in the case of large grains they propagate freely over a large distance right through grains (transcrystallite propagation) while for small grains they propagate predominately along grain boundaries with branching (intercrystallite propagation).

  • Longitudinal Dynamics of a Charged-Particle Bunch in a Traveling Wave
    • Abstract: In this work, which is devoted to the longitudinal dynamics of charged particles in the field of traveling wave, on which the theory of the resonance method of acceleration is based, a transition is made from the dynamics of individual charges to the dynamics of charge bunches as a whole in order to increase the effectiveness of mathematical modeling. A similar problem has already been solved for nonrelativistic bunches. Using the same method, the solution is extended to relativistic bunches. The method is based on the Lagrange equation for the longitudinal motion of a charged-particle bunch in the field of traveling wave; the solutions are the longitudinal size of a bunch and the width of the energy spectrum. The self-field of the bunch is taken into account in the equation and the limitations of linear approximations are eliminated.

  • Spatiotemporal Distribution of the Energy Absorbed by the Electronic
           Subsystem During the Retardation of a Fast Heavy Charged Particle in
    • Abstract: The characteristics of the spatiotemporal distribution of the energy absorbed by the electronic subsystem during the propagation of fast heavy charged particle in matter – the time dependence of the relative fraction of the energy absorbed by electrons per unit path length of a heavy charged particle and as a function of the average squared distance characterizing the size of the region of absorption – are found on the basis of the solution of the linear kinetic equation. These results are obtained in a dimensionless form and depend on the energy of the heavy charged particle per nucleon and on the average ionization potential of the atoms of the material. The characteristics for concrete particles and materials can be determined using the appropriate dimensional variables.

  • Measurement Fitness of Samples for Fatigue Crack Resistance Tests
    • Abstract: The concept of the ‘measurement fitness of a sample for materials tests’ is introduced. Evaluations of the measurement fitness of the six most common samples for fatigue crack resistance tests are given. It is shown that other conditions remaining the same a sample should be chosen taking account of its measurement fitness in terms of the range of the admissible change in length of a fatigue crack or the range of variation of the stress intensity factor.

  • Environmental Safety Assessment of Krasnoyarsk Krai Based on a Public
           Health Risk Analysis
    • Abstract: The environmental safety of Krasnoyarsk Krai, which possesses a large industrial potential, is evaluated using the methodology of public health risk analysis. It is shown that chemical contamination of the environment is one of the significant factors determining the health of the krai’s population. The effect of the radiation factor associated with the operation of the Mining and Chemical Combine is extremely limited compared with the sources of chemical risk. The radiation risk is 100–100,000 times lower than the chemical risks for public health.

  • Purification and Enrichment of Regenerated Uranium in a Double Cascade
    • Abstract: The effi ciency of two cascades is investigated on the basis of a computational experiment: in the fi rst one regenerated uranium is purifi ed and in the second one low-enrichment uranium is produced from the purifi ed waste of the fi rst one. It is shown that the use of R cascades for purifi cation makes it possible to reduce the content of 232,234U considerably, but it leads to high 235U concentration 60–90% in the steps. To eliminate this, the purifi cation by removal of 232,234U should be done in optimal cascades, calculated according to the data obtained with the R cascades, with the feed shifted into the product step. This makes it possible to reduce the 235U content in the steps of the cascade to 20% or less. The quality of the lowenrichment uranium produced from the purifi ed regenerated uranium can be improved by using dilution and enrichment operations, which make it possible to reduce the 236U content.

  • Investigation of Experimental Dispersion Fuel Elements with an
           Aluminum-Based Matrix for High-Flux Research Reactors
    • Abstract: A variant of experimental dispersion fuel elements with fuel based on uranium dioxide as fissile material in a silumin matrix, which have been proposed for modernizing the core of the SM reactor and are irradiated in a wide spectrum of neutron-physical and thermophysical parameters in the reflector channel of the reactor, is investigated. A nonuniformity with fuel density two times higher than the average over a fuel element, viz., a cluster of uranium dioxide particles in the central zone of the kernel, has been found in the distribution of the fuel phase in the fuel elements. The thermophysical calculations show that for such a distribution of fuel particles the temperature of the fuel composition with heat flux density from the fuel-element surface >6 MW/m2 can reach the melting temperature of the matrix. This is confirmed by investigations of fuel elements with appreciably larger volume and shape change. To increase the serviceability of the fuel elements, ways of improving their design and the material composition of the fuel mix are proposed.

  • Transfer of the VVR-K Research Reactor to Low-Enrichment Uranium Fuel as a
           Basis for the Development and Adoption of VVR-KN Fuel Assemblies
    • Abstract: The results of development work and reactor tests of VVR-KN fuel assemblies for transferring the VVR-K research reactor to low-enrichment fuel are presented. The characteristics of VVR-Ts and VVR-KN fuel assemblies as well as the VVR-K reactor loaded with low- and high-enrichment fuel are compared. The VVR-K characteristics improved upon switching to VVR-KN fuel assemblies with low-enrichment fuel.

  • Monitoring the Condition of Safety Barriers in Nuclear Power Plants
    • Abstract: The technical requirements of a system that continually monitors the condition of the safety barriers of nuclear power plants are substantiated. It is shown for the example of the Rostov NPP that power units with VVER which are operating, under construction, or in the design stage can be equipped with a measuring system for monitoring radiation leaks from the steam generators. This improves safety (by not allowing emergency situations) and increases the installed capacity utilization factor (by eliminating unjustified shutdowns of power units) of operating power plants.

  • Characteristics of Entry into the Xenon Oscillations Regime in a Reactor
           with Feedback on the Coolant Temperature
    • Abstract: The simplest approximations (one-dimensional reactor, single-group diffusion model of neutron transfer) are used to study the characteristics of xenon oscillations in a reactor with negative feedback on the coolant temperature. It is shown that in this case, in contrast to the situation where the predominant feedback is on the neutron flux density, the emergence into the xenon instability regime will manifest in the form of perturbations of the reactor power and energy release simultaneously. In addition, the deformations of the energy-release field grow with increasing neutron flux and physical dimensions of the reactor.

  • Dose Factors for Photon Accumulation in Uranium Oxides and Hexafluoride
    • Abstract: The first results of a calculation of the dose factors of photon accumulation in uranium oxide UO2, triuranium octoxide U3O8, and uranium hexafluoride UF6 for a point isotropic monoenergetic source of photons with energy from 0.01 to 5 MeV for material thickness ranging from 0.5 to 25 μd are presented. The calculations are performed in infinite and barrier geometry taking account of all interactions of photons with matter. The possibilities of determining the accumulation factors of these mixtures on the basis of the accumulation factors of the individual elements are examined. Corrections for the barrier effect of the material are determined; it is noted that they are independent of the thickness, material, and energy of the source photons. The information obtained will make it possible to lower the computational error of the radiation dose when working with these materials, which are widely used in the nuclear fuel cycle.

  • Integral Indices of the Radiological Effect of Open and Closed Fuel Cycle
           Objects on the General Population
    • Abstract: The collective dose is examined as an integral characteristic of the radiological effect of nuclear fuel cycle enterprises on the general population. A relation is obtained for evaluating the ecological factor, which takes account of the specifics of radionuclides from the standpoint of their migration capacity and the particularities of dose load formation. The ecological factors are calculated for 241Am, 242mAm, 242Am, 243Am, 242Cm, 243Cm, 244Cm, 245Cm, 246Cm, 247Cm, 248Cm, 237Np, 238Pu, 239Pu, 240Pu, 241Pu, 242Pu, 244Pu, 235U, 236U, and 238U. Links where the activity of the daughter radionuclides was taken as equal to the activity of long-lived precursors are singled out in the decay chains of the actinides. The dynamics of the yearly collective dose for the general population, formed by individual actinides with activity 1 Bq in the emissions and their decay products, for a long period of time is calculated. The results are suitable for performing comparative radioecological assessments of enterprises in open and closed nuclear fuel cycles.

  • Thermodynamic Modeling of the Phase Composition of Mixed Uranium-Plutonium
           Mononitride with Impurity Oxygen Under Irradiation to Burnup 140
           GW·days/ton and Temperature 900–1400 K
    • Abstract: Thermodynamic modeling of the phase composition of mixed uranium-plutonium mononitride with impurity oxygen as a function of burnup and temperature under irradiation by fast neutrons has shown that the accumulation of fission products results in the formation of heterogeneous fuel: a multicomponent solid solution based on uranium-plutonium oxynitride that contains yttrium, zirconium, and lanthanides and separate nitride, oxide, metal, and intermetallides phases as well as alkaline-metal iodides and, apparently, bromides. The change in the content of these phases as a function of burnup to 140 GW·days/ton and temperature 900–1400 K is calculated. The effect of the individual phases formed in the course of irradiation on the effective thermal conductivity of the fuel is evaluated together with the diffusion coefficient of xenon atoms in the fuel kernel.

  • Analytical Possibilities of Detecting Trace Quantities of Beryllium by
           ERIAD Mass-Spectrometry
    • Abstract: The possibility of mass-spectrometric determination of the beryllium concentration in the air in work rooms is examined. Experiments have shown that the ERIAD ion source (electro-sprayng with controlled atomization in the source) gives the required rapid-analysis of the beryllium content, including at a level 10 times lower than the maximum admissible concentration. Evaluations show that such analysis takes no more than 30 min, including sample preparation; one mass-spectrometer can service 10–12 sampling points.

  • Neutron-Physical Calculations of a Nuclear Reactor: Computing Time
           Reduction by Digital Filtration
    • Abstract: An algorithm is proposed for performing neutron-physical calculations of a reactor using digital signal processing methods. It is shown that the algorithm’s combined use of the classical methods of numerical analysis and high-frequency digital filters makes it possible to calculate accurately and rapidly the neutron macrofield on a coarse grid and to organize the neutron-physical calculations in a new way, greatly reducing the number of iterations on a fine grid. Computer modeling shows that even for a one-dimensional reactor the proposed rational combination of the computational results on coarse and fine grids gives a several-fold reduction of the computing time.

  • Improvement of the Thermohydraulic Operating Regimes of Deaerators in the
           Makeup and Boron Regulation System with Packed Columns
    • Abstract: One of the main pieces of equipment in the makeup and boron regulation system for the first loop of an NPP is the deaerator, whose functions is to degas the coolant removed from the first loop of a nuclear reactor in different operating regimes. Operating experience has shown that a deaerator design with packing columns does not give the requisite margin to flooding. Deaerator calculations suggesting further ways to solve the problem are presented.

  • Effect of the Degree of Perfection of Reactor Graphite on Performance
    • Abstract: Experimental data on the density changes occurring in graphite blocks of RBMK masonry in the course of operation of the reactor are presented. They show significant variance due to the nonuniformity of the radiation-induced change in the properties which is associated with the difference in the degree of perfection of the initial graphite. Experimental data on the dependence of the radiation-induced deformation at the shrinkage stage versus the size of the graphite crystallites are presented. An attempt is made to explain the mechanisms giving rise to this dependence. Experimental data showing that for temperature changes within certain limits from T1 to T2 the graphite transforms under irradiation into a state that would be observed under irradiation at T2 at the outset. A relation for determining the difference between the maximum depth of shrinkage of the graphite samples irradiated at temperatures T1 and T2 is proposed on the basis of an analysis of the experimental data.

  • Health Risk of Radon: Assessment Methods and Practical Applications
    • Abstract: Models of the dose–effect relation for the effect of radon on human health are analyzed. It is concluded that these models must be improved. A new and improved dose–effect relation is developed. An assessment of the health risk of radon, including an assessment of the radon exposure dose and a new dose–effect relation for risk assessment proper, is described. A method is proposed for use on the territory of our country. This method is used to calculate the risk for two hypothetical variants of the effect of radon on humans.
