  • Electrochemical Reduction of Uranium Dioxide in LiCl–Li2O Melt

    • Free pre-print version: Loading...

      Abstract: The electrochemical reduction of dense and porous pellets made from uranium dioxide in a molten LiCl electrolyte with Li2O content 1–2 wt.% was investigated. Electrolysis was conducted in a galvanostatic regime at cathode potential more positive by 0.05–0.15 V than the formation of a phase based on liquid lithium. It is shown that with such an electrolyzer uranium dioxide samples are almost completely reduced to metal after passing 160–180% of the theoretical amount of electricity. The metallized product has a porosity of 55–84%, depending on the density of the original tablets. This leads to significant capture of the salt electrolyte, whose removal by vacuum distillation is complicated by reduction of uranium dioxide. A great influence was noted on the stable operation of the cell of the anode compartment and, above all, the anode material. The best results were obtained using ceramic anodes made of nickel (II) oxide doped with lithium oxide.

    • Free pre-print version: Loading...

      Abstract: This work is devoted to the assessment of the corrosion resistance of the body of the melt trapping setup under operating conditions at nuclear power plants. A definition of corrosion losses based on a complex of accelerated tests of the metal and the parameters characterizing the corrosivity of the atmosphere is examined. It is shown that during the entire service life of the melt trapping setup (up to 80 yr) the corrosion depth does not exceed 2.6% of its thickness and does not significantly affect the integrity. But the housing should be protected from corrosion.

  • Development and Verification of 60Co Accrual Calculation and Management
           Methodology

    • Free pre-print version: Loading...

      Abstract: RBMK reactors have unique potentialities for producing commercial radionuclides. Long-term planning and computational support are required to increase the production efficiency and improve the qualitative characteristics of radionuclides. A technique was developed and verified for performing three-dimensional calculations of the 60Co specific activity accumulation in additional absorbers located in the RBMK core. Based on precision 3D neutronic calculations performed using the MCU-RBMK code, a library was prepared for calculating the 60Co generation rate in individual capsules of an additional absorber for the SADCO code. The developed ACCORD software package solves the equation of isotope kinetics in an irradiated target, broken down into time steps. At each step, the capture rate on cobalt is determined from SADCO code calculations. The ACCORD code was verified on the basis of data on irradiation, unloading, and processing of additional absorbers and put into experimental operation.

  • Laser Device for Lowering the Uranium Detection Limit in Technological
           Environments of NPP

    • Free pre-print version: Loading...

      Abstract: The detection of uranium in the process media of NPP is of great importance for the safety of NPP. The detection limit reached for uranium is equal to 1–2 μg/L, which is insufficient to detect an early stage of an emergency operating regime. The present investigation of the possibility of using multipass absorption-selective spectroscopy and a laser device based on it showed that the detection limit for uranium can be reduced by about 100-fold compared to the currently used standard single-pass absorption-selective spectroscopy method – from 1–2 to 0.01–0.02 μg/L.

  • Ordinary Gas-Centrifuge Cascades for Purifying Reprocessed Uranium
           Hexafluoride from 232,234U

    • Free pre-print version: Loading...

      Abstract: It is proposed to use an ordinary three-stream cascade with several types of stages in terms of the number of gas centrifuges in order to lower the 232,234U concentration in reprocessed uranium hexafluoride. Its parameters, giving a high output of the product with close to feed concentration of 325U going into the waste and considerably lowered 232,234U were determined. A high-activity product, which it is expedient to dilute with waste uranium hexafluoride to a nuclear safe mixture with 235U concentration <1%, is formed in the product. A computational experiment was performed. It is shown that in terms of 232,234U the post-enrichment product meets ASTM C996-20 specifications for enriched commercial uranium hexafluoride.

  • Methodology for Evaluating NPP Economic Indicators Including Safety

    • Free pre-print version: Loading...

      Abstract: Procedures are proposed for evaluating the impact of safety aspects, which are associated with the possibility of the occurrence of severe accidents, on economic indicators of NPP, taking into account probability of their realization. The relevant parametric calculations are performed in order to assess the impact of the conditions and consequences of severe beyond design basis accidents on the incremental cost of electricity. It is shown that the contribution from expenditures on clean-up after a serious beyond design basis accident to the incremental cost of electricity is very small if occurrence probability is less than 2·10–8–2·10–6 1/(reactor·yr), depending on the nominal electric power of the power unit.

  • Investigation of Coolant Flow in an RITM-Reactor Fuel Cassette

    • Free pre-print version: Loading...

      Abstract: The results of coolant flow investigations of a fuel rod bundle of an RITM-reactor fuel cassette for a small nuclear power plant are reported. The purpose of this work is to investigate the redistribution of the axial and transverse flow velocities as well as the axial coolant flow rate behind a spacer grid. For this purpose, experiments were performed on an aerodynamic stand using a scale model of a fuel rod bundle of an FA. A region with characteristic type cells was chosen for investigation. The coolant flow is represented by cartograms of the distribution of the transverse and axial velocities as well as by graphical plots of the distribution of the axial velocity and flow rate through the characteristic types of cells. The resulting experimental database can be used to verify modern CFD programs as well as programs for performing cell-by-cell thermohydraulic calculations of a core.

           Pulse-Packet Control

    • Free pre-print version: Loading...

      Abstract: The efficiency and effectiveness of logging equipment are largely determined by the amplitude-time characteristics of neutron fluxes, which depend on the parameters of the magnetic field generating systems, anode voltage pulses, gas composition, gas pressure, and others. The processes of restoration of the breakdown strength of gas in the interelectrode gap during the pauses between the supply voltage pulses affect the discharge ignition conditions and stability of the neutron flux characteristics. The results of experimental investigations of the pulse-packet operating regimes of Penning ion sources under conditions of wide adjustment of the parameters of the control and power systems for neutron tubes are reported.

  • Technical and Economic Features of IAEA Safeguards Application at NPPs
           with a Fast Reactor and On-Site Fuel Cycle

    • Free pre-print version: Loading...

      Abstract: The large-scale use of nuclear energy makes us think about not only technical and economic efficiency but also the risk of dual-use of materials and nuclear knowledge. One of the important aspects from this standpoint is the adherence to the international safeguards regime, which protects the fuel cycle against the possible use of materials and technologies for military purposes. Significant experience has now been gained in the application of IAEA safeguards. In this context, questions associated with their financial security and particularities in light of the proposed exporting of NPP with a fast reactor, including installations with an on-site fuel cycle, take on importance.

           Countering Illicit Trafficking

    • Free pre-print version: Loading...

      Abstract: A method is proposed for identifying fragments of nuclear material by analyzing their shapes, structural features, and sizes. It is shown that in most cases identification is possible in a remote-sensing regime in which an unknown fragment is discovered in one region but the identification center lies in another region, using not an actual fragment but rather digital models or digital photographs of a fragment. Remote identification becomes the only possible method of identification if the level of radiation emission from the fragment precludes manual handling. A mock-up of the identification system was built and its performance was confirmed on simulators of nuclear-material fragments.

  • Refinement of the Parameters of a Reactor Installation and Thermohydraulic
           Characteristics of the Main Equipment, Based on Commissioning Results for
           a Power Unit with BN-800

    • Free pre-print version: Loading...

      Abstract: The computer programs used to validate the thermohydraulic characteristics of equipment and parameters of fast sodium reactors in normal operation are described. The actual efficiency of heat transfer in the intermediate heat exchangers (IHE) in BN-800 is given, and a comparative analysis is performed using the calculated data obtained in one- and two-dimensional approximations. A heat-exchange surface margin is proposed, and can be used in designing IHE similar to the IHE considered in this article. The actual hydraulic characteristics of the first and second loops of BN-800 are analyzed and the running speed of the MCP-1, -2 pumps is determined. It is shown that the running speed of MCP-1, -2 is 5 and 8%, respectively, lower than the design speed. Comparison of the operational and design thermohydraulic parameters of BN-800 in normal operation showed satisfactory concurrence. The correctness of the start-up and planned shutdown algorithms incorporated in the BN-800 design is confirmed.

      Abstract: The results of calculations and experimental determination of the neutronics characteristics of the IRT-T research reactor are presented. The IRT-T reactor is a pool reactor with rated thermal power 6 MW(t). The neutronics characteristics of the reactor were determined during the 2016–2017 runs. The calculations were performed using the precision software MCU-PTR with the MDBPT50 baseline nuclear constants. The experimental determination of the reactivity parameters was obtained by analyzing the current values of the reactor’s standard control and protection system. Different approaches and methods for determining the efficiency of the reactor controls were considered. The calculations and experimental work were conducted in order to assess the effects of reactivity.

  • Change of Interatomic Forces in Metal Under the Action Of Ionizing
           Radiation

    • Free pre-print version: Loading...

      Abstract: The interatomic interaction in a metal in the presence of ionized states was investigated by means of pseudopotentials. The parameters of the form factors were determined by the quantum defect method using the spectroscopic terms of free ions. It is shown that ionization leads to a significant change in the interatomic interaction. Atoms land on the repulsive branch of the potential function, as a result of which the crystal lattice passes into a nonequilibrium state. The screening properties of conduction electrons strongly depend on their concentration, which can lead to a local change in the elastic properties of matter near the track of a fast charged particle.

           Compositions Simulating Uranium-Thorium Dispersion Nuclear Fuel

    • Free pre-print version: Loading...

      Abstract: A promising direction of advancement in nuclear energy is the use of uranium-thorium dispersion nuclear fuel, which consists of fissile metal (uranium, thorium) oxides evenly distributed in an oxide matrix having a high thermal conductivity and small neutron absorption cross-section. The methods of obtaining oxide composites (sol-gel process, separate production, mechanical mixing, and others) are multistaged, do not afford a uniform distribution of phases, and have high energy consumption. This article discusses the plasma- chemical synthesis of nanosized oxide composites in an air-plasma flow of dispersed aqueous-organic nitrate solutions with heat value equal to at least 8.4 MJ/kg, affording significant energy consumption reduction and uniform phase distribution with the required phase composition.

      Abstract: The predictables of non-stationary desublimation of UF6 in vertical submersible tanks with vertical ribbing were investigated by means of numerical modeling using a simplified three-dimensional mathematical model. The computational results for the average capacity of tanks with vertical ribbing with volume 1–4 m3 are given as a function of the width and length of the vertical. It is shown that the average capacity of tanks with vertical ribbing can be increased by changing the width and length of the ribs.

      Abstract: The results of quantum-chemical modeling of the interaction energy of an interlayer cation with the crystal structure of illite, which does not contain water molecules, are presented. It is shown that the binding energy of a single ion Li+, Rb+, and Cs+ within the working cell changes by the amount 5 eV for Li+, 25 eV for Rb+, and 110 eV for Cs+. Potential wells of the binding energy between an interlayer ion and illite are observed in the working cell. The Li+ potential wells touch and are oriented along the line connecting the Al atoms. The potential wells of the interlayer ions Rb+ and Cs+ are spatially limited. Li+, Rb+, and Cs+ ions cannot diffuse in a dry illite crystallite.

      Abstract: Atmospheric precipitation introduces significant changes in the gamma background, making it difficult to analyze data from radiation monitoring systems. A criterion for identifying changes in the gamma background caused by atmospheric precipitation is proposed. Measurements of changes in the gamma background and the level of precipitation were performed at two independent observation sites. The time spectra of the gamma background were analyzed. The characteristic elements caused in the spectra by atmospheric precipitation are identified and classified. It is shown that the changes brought about in the gamma background by atmospheric precipitation can be identified according to the exponent of an exponential function describing the gamma background reduction following after the maximum is reached. If several consecutive peaks are present in the spectrum, identification is possible according to the gamma background reduction after the final peak.
