  • Refinement of the Pseudosource Method of Calculating RBMK Cluster Cells
    • Authors: N. V. Sultanov
      Abstract: The KLARA option is now being used to perform multigroup calculations of VVER and RBMK cluster cells and to prepare few-group characteristics of cells in the WIMS-SH-2.0 and SVL systems. The transition to 69-group calculations of RBMK cluster cells has revealed instability. Analysis has shown that the instability is associated with a discrepancy in the type of pole in several integrals arising in the calculation of the angular moments of the sinusoidal components of the Greens function. The removal of this singularity by adding two lines of the angular moments of the sinusoidal components eliminated this instability. The difference of K∞ calculated using the KLARA and PIJ options was less than 0.2% for cluster cells with and without fuel.

  • Estimate of the Possibility of a Self-Sustaining Nuclear Chain Reaction
           Accompanying Core Meltdown in a Research Reactor with IRT-M Type Fuel
           Assemblies
    • Authors: V. A. Nasonov; Yu. E. Pesnya; A. V. Sidorenko
      Abstract: Computational estimates are made of the possibility of a self-sustaining nuclear chain reaction in beyond design basis accidents with core meltdown in a research reactor, where IRT-3M or IRT-4M fuel assemblies with high- and low-enrichment fuel are used. The certified MCU-PTR Monte Carlo code is used for the computational estimates. A conservative approach (estimaticphon from above) is used. It is shown that a selfsustaining nuclear chain reaction is impossible during core meltdown.

  • Comparison of Closed Nuclear Fuel Cycle Technologies
    • Authors: A. Yu. Shadrin; V. B. Ivanov; M. V. Skupov; V. M. Troyanov; A. A. Zherebtsov
      Abstract: The aim of this work is to compare different approaches to nuclear fuel cycle closure from the standpoint of plutonium utilization, fuel type, and reprocessing technology. It is shown that the choice of mixed uraniumplutonium nitride fuel for fast reactors will make it possible to effectively close the NFC and at the same time develope safe nuclear power; the combined (pyrochemical + hydro) technology will make it possible to reprocess any type of high-burnup short-decayed irradiated fuel from fast reactors and to obtain the final uranium-plutonium-neptunium product suitable for use in any fuel production technology.

  • Reliability Analysis of APCS
    • Authors: V. N. Durnev; A. N. Chernyaev; V. S. Tsarev; I. I. Galiev
      Abstract: This article is devoted to the problems of reliability analysis of APCS. The advantages and disadvantages of different methods of qualitative reliability analysis of technical systems are examined, and the need for combined use of all methods studied is shown and validated. The most appropriate criterion of evaluation is found on the basis of an analysis of the primary reliability indices of the APCS means. This research shows that there is a need for developing a method of reliability and safety analysis that will make it possible to evaluate the risk of systems which are under development, raise the reliability indices to the level of economic calculations, and choose the APCS means taking account of economic factors, which would lower the cost of development work and delivery.

  • 235 U Resonance Structure Effect on Computed Characteristics of Critical
           Assemblies in Large Physical Testing Facility with Softened Neutron
           Spectrum
    • Authors: O. N. Andrianova; V. A. Dulin; V. V. Dulin; A. A. Andrianov
      Abstract: An unusual change of the contributed reactivity of uranium samples with 90% enrichment depending on the size was observed during experiments on the critical assembly of the large physical testing facility with a softened neutron spectrum: the reactivity became negative upon insertion of thin samples. The agreement between the calculations and experimental data in the description of this unusual change of reactivity was obtained by making changes in the radiative capture cross section of 235U and the factors of resonance self-screening in the group approximation and by taking account of the possible missed narrow resonances of 235U in the point representation description of the experiment.

  • NPP Nuclear Power Reactors as 14 C Sources
    • Authors: V. P. Rublevskii; V. N. Yatsenko
      Abstract: Research has determined the actual 14C emissions from all types of reactors. The average emissions are (TBq/yr): VVER-440 (V-179, -230) 3.1 ± 1.5; VVER-440 (V-213) 1.3 ± 0.5; VVER-1000 2.0 ± 0.7; RBMK-1000 2.4 ± 1.6. The obtained data agree satisfactorily with the calculations, so that they can be used to predict the emissions from commissioned power reactors. The normalized 14C emissions from different types of foreign reactors, which approximately correspond to domestic reactors, are presented in UNSCEAR reports. The total atmospheric emissions of 14C by NPP reactors over the entire period of their operation (in 2015) equaled ~1.34 PBq. Over this same period about 54 PBq of native 14C entered the carbon cycle of the Earth’s biosphere; this is almost 50 times greater than the surveyed NPP.

  • Recovery of the Point Pseudoresonance Structure of Cross Sections in the
           Region of Unresolved Resonances
    • Authors: V. M. Shmakov
      Abstract: A model is proposed for recovering the point cross sections in the region of unresolved resonances. The approach consists in using probability tables P i (σ) to construct the effective cross sections σ i ′ (E) on some choice of energy intervals [E i , E i+1]. In constructing the effective cross sections the densities P i (σ′) and P i (σ) are preserved. This makes it possible to preserve on the intervals [E i , E i+1] characteristics of the neutron–matter interactions such as the average cross section, average free path, transmission function, and others. The use of pseudoresonances in the field of unresolved resonances is not distinguished from the use of ordinary point cross sections in the region of resolved resonances. The proposed approach does not require modifications of the library formats and modeling schemes for the neutron trajectories in Monte Carlo programs. The calculations of two problems showed good agreement between the calculations of the change ΔK eff using probability tables and the MCNP code and calculations using the PRIZMA code, in which pseudoresonances were used.

  • Measurement of the Kinematic Viscosity of the Eutectic LiF–AlF 3
    • Authors: A. V. Merzlyakov; V. V. Ignat’ev; S. S. Abalin
      Abstract: The kinematic viscosity of a eutectic salt mixture with the molar composition 0.855LiF–0.145AlF3 at temperatures to 850°C is measured by means of damped torsional vibrations of a cylinder with the experimental liquid. This salt mixture is of interest for separating actinides and lanthanides during reprocessing of spent nuclear fuel. Below 800°C the behavior of the system is found to differ from that of a normal liquid. Such behavior is explained by precipitation on solid surfaces. The precipitated fraction of the material is evaluated as a function of temperature. An analytical expression is obtained for the kinematic viscosity at temperatures above 800°C. The standard deviation of the kinematic viscosity evaluated assuming the dispersion to be independent of temperature equals 0.006·10–6 m2/sec. The total error of measurement does not exceed 3%.

  • Effect of Fission Products and Oxygen and Carbon Impurities in (U, Pu)N on
           the Heat-and-Mass Transfer Coefficients and Xenon Yield
    • Authors: I. A. Deryabin; V. S. Kharitonov; D. Yu. Lyubimov
      Abstract: Irradiation of uranium-plutonium mononitride by fast neutrons results in the formation and accumulation of fission products, which, for example, lanthanides, zirconium, and yttrium, dissolve in the fuel solid solution, changing its chemical composition and stoichiometry, or precipitate in the form of individual condensed phases, changing the phase composition of the fuel. These phase inclusions are formed inside and on the boundaries of fuel grains, changing the coefficients of heat-and-mass transfer. A change in the effective coefficient of heat-and-mass transfer results in a transformation of the temperature field in a fuel element, which means that the temperature part of the diffusion coefficient changes. The diffusion coefficient in solid phase inclusions is different from the diffusion coefficient in the fuel matrix, as a result of which the effective diffusion coefficient changes. A model of the yield of stable, radioactive, inert gases from uraniumplutonium mononitride fuel is presented and used to calculate the xenon yield taking account of the changes in the coefficients of heat-and-mass transfer and diffusion.

      Abstract: A particle and ion detector based on an epitaxial layer of synthetic diamond is investigated. The p–i structure consists of a substrate comprised of HPHT p-type diamond, strongly doped with boron, on which ~10 μm thick, IIa-type, diamond CVD-film is deposited. Continuous contacts were deposited on the substrate and diamond CVD fi lm. The current-voltage characteristics of the p–i structure with deposited platinum contacts were measured. The detector was tested in fluxes of protons, deuterons, and α-particles obtained by means of an ion accelerator. The use of a diamond detector as a particle analyzer is promising in view of its unique properties, such as high radiation resistance and the possibility of operating at high temperature. The energy resolution of the detector and the minimum detectable particle energy were determined.

  • Lessons from Chernobyl and Fukushima and Advanced Control Concepts for
           Severe Accidents
    • Authors: L. A. Bol’shov
      Abstract: The year 2016 marks the 30th anniversary of the accident in the No. 4 unit of the Chernobyl NPP and the 5th anniversary of the accident at the Fukushima NPP in Japan. The Chernobyl accident substantially changed the public’s attitude toward severe accidents at NPPs, promoting on the one hand modernization and improvement of safety systems and on the other hand a higher safety culture by harmonization of standards and regulations, and adoption of deeply echeloned protection and a scientifically validated approach to the analysis of accidents. The Fukushima accident revealed a new class of accidents – extreme actions caused by naturally occurring cataclysms and/or different external actions, which actually are identical to loss of a large part or all of the means for controlling an accident. The present article examines the main lessons on accidents in terms of understanding the phenomenology of the events occurring during severe accidents and confirms the importance of the deterministic component of the safety concept. At the same time, it emphasizes that special attention must be given to hydrogen safety, systems for prolonged removal of residual heat, emergency readiness, and emergency response under the extreme conditions of severe accidents. The computational means used to develop accident counter-measures must be properly set to take account of the design features of the reactor facility, the containment of the NPP, and the adjoining territories in order to determine the time required to implement the procedures for controlling accidents and mitigating the consequences.

  • Dynamics of a Charged-Particle Bunch in a Travelling Wave Field with
           Focusing by a Uniform Magnetic Field
    • Authors: V. K. Baev
      Abstract: This work is devoted to charged-particle dynamics in a traveling wave field that is central to the theory of the resonance method of acceleration. The equations of longitudinal and transverse motions of a bunch, focused by a longitudinal uniform magnetic field, are derived, for the first time, within the framework of the theory of envelopes. The Lagrangian of the longitudinal and transverse motions is central to the method used; the derivation of these functions is based on the following assumptions: the emittance of a bunch is approximated by an ellipse and the bunch itself in the configuration space is approximated by an ellipsoid of revolution. The solutions of test problems in which the results obtained by the method of individual particles are compared with the results obtained with the derived equations show satisfactory agreement. The equations of the envelopes could find application in the design of accelerating systems of linear resonance accelerators with focusing by a uniform magnetic field. This pertains to, first and foremost, linear electron accelerators in which focusing of this kind is often used.

  • Use of Enriched Uranium in a Fast Reactor with Lead Coolant
    • Authors: I. A. Volkov; V. A. Simonenko; I. R. Makeeva; N. D. Dyrda; M. N. Belonogov; M. A. Trapeznikov
      Abstract: The transition of a lead-cooled reactor initially fueled with enriched uranium into an equilibrium operating regime is examined. Regenerated fuel is used consistently upon closure of the fuel cycle. The defi ciency of recycled fissile material is compensated by enriched uranium. The time to the equilibrium regime is 45 years. The breeding ratio reaches 1 in approximately 38 years. The neutron-physical characteristics were calculated using the multigroup diffusion code Arktika and the PRIZMA spectral code, which employs the Monte Carlo method. The RISK code was used to calculate the evolution of the nuclide composition. The change in the nuclide composition in the external fuel cycle was calculated after each microrun.

  • High-Priority R&D Problems of Advanced Fast Sodium Reactors
    • Authors: V. M. Poplavskii; Yu. E. Bagdasarov
      Abstract: The transition to new design and circuitry requires careful validation of the efficacy of the new solutions. For the sodium-water BN-1200 macro-modular steam generator, the damage is determined by the failure of the structural material in the zone of a water leak into the sodium and the amount of water entering the coolant. The parameter that ultimately determines the magnitude of the damage is the time interval between the start of a small leak and the actuation of the steam generator’s protection system. Acoustic methods are effective for decreasing the lag of the indication system. The design is based on the use of two-frequency ranges – vibro-acoustic (0.1–40 kHz) and ultrasonic (40–500 kHz) – of high-sensitivity acoustic sensors, and fast software-hardware methods of analyzing acoustic signals in real-time. The presence of thermal insulation and protective jackets on the sodium equipment and pipelines strongly affects the character of the outflow and burning of the sodium and eliminates dispersal. Analysis shows that there are strong grounds for reducing the conservatism (safety margins) in studying emergency regimes associated with sodium leaks.

  • Corrosion Effect on Concrete Barrier Life of a Decommissioned AD Reactor
    • Authors: M. V. Antonenko; D. O. Chubreev; G. V. Kuznetsov
      Abstract: A mathematical model of diffusion of calcium hydroxide in the system concrete barrier–ambient environment was developed to determine the influence of corrosion processes of the first and second kinds, engendered by water and radionuclides, on the lifetime of a concrete barrier of a decommissioned commercial uranium-graphite reactor. The CaOH distribution over the thickness of the barrier in a single crack was determined. Calculations were performed to determine the CaOH concentration over the barrier thickness and to analyze the effect of corrosion and the use of S-3 superplasticizer in concrete on the lifetime of the barrier. The superplasticizer can extend the operating lifetime of the concrete barrier to 800 years.

  • Purification of Regenerated Uranium in a Two-Cascade Scheme Using
           Intermediate Product Extraction in One of the Cascades
    • Authors: V. A. Palkin
      Abstract: The efficiency of two-cascade schemes for purification of regenerated uranium is investigated on the basis of a computational experiment. In the first cascade, by shifting the feed toward the waste the waste flow is purified by removing 232U with 235U enrichment to 5%. In the second cascade, the flow is additionally purified by removing 232,234,236U in the intermediate product flow and natural raw material is fed into the main feed flow and low-enrichment commercial-grade uranium is obtained in the main product flow. It is shown that purification can be conducted by feeding it into the step minimizing the total feed flow of the steps or into the first step of the cascade. Low-enrichment commercial-grade uranium hexafluoride meeting ASTM specifications in terms of 232,234,236U can be produced from the purified product obtained in the intermediate product flow.

  • History and Operation of the First Two Units of the Beloyarskaya NPP
    • Abstract: The history and development are presented of the unique power-generating units at the Beloyarskaya NPP with in-reactor steam superheating with AMB reactors that are thermal channel reactors with graphite moderator, whose core consisted of evaporation channels (2/3 of the core) with tubular fuel elements with heat removal by boiling water under pressure 13 MPa and steam superheating channels (1/3 of the core) with tubular fuel elements with heat removal by superheat steam. A description is given of the particularities of the thermal scheme, the problems associated with the development and testing of the primary equipment used in a power-generating unit, and the experimental research conducted on loop setups and experimental stands built at the Obninsk NPP and setups of the Institute of Physics and Power Engineering. The results of computational and experimental research performed in validation of the power-generating units and startup operations at the Beloyarskaya NPP are presented. Emergency situations arising during startup are described. The experience gained in developing the first two units of the Beloyarskaya NPP is used in the development of a series of RBMK-type reactor facilities.
