  • Application of a proton microprobe to study diffusion profiles of Ce in synthetic aluminosilicates 
    Bondarenko, V.N.; Goncharov, A.V.; Kuz’menko, V.V.; Pistryak, V.M.; Saenko, S.Yu.; Sukhostavets, V.I.; Surkov, A.E. (Вопросы атомной науки и техники, 2005)
    The procedure of measuring the diffusion profiles of Cerium by means of a proton microprobe was developed. These profiles in the synthetic aluminosilicate matrix synthesized on the base of kaolin and red granite were measured
  • Estimations of high-temperature diffusion in Chernobyl’s concrete construction 
    Dikiy, N.P.; Dedik, A.N.; Dovbnya, A.N.; Uvarov, V.L. (Вопросы атомной науки и техники, 2005)
    The content of isotopes Ti, Ni, Zr, Cs and U in the cores, which was taken from the concrete construction of ChAPS, was studied by the gamma-activation analysis. It has been developed a numerical model to analyze heat ...
  • Evaluation of isotope contents of plutonium in reactor emissions by gamma-radiation of ¹⁰⁶Ru, ¹¹¹Ag and ¹²⁵Sb 
    Bykov, V.T.; Elmansury, A.M.; Olejnik, S.N.; Rudak, E.A.; Tulubtsov, A.Ya.; Vodin, A.N.; Yachnik, O.I. (Вопросы атомной науки и техники, 2005)
    It is offered to use nuclides ¹⁰⁶Ru, ¹¹¹Ag and ¹²⁵Sb for evaluation of transuranium elements content in the spent fuel of HPOR-1000 reactor. It is found that ¹²⁵Sb is the most suitable for estimations of emergency reactor ...
  • Influenсe of different factors on sorption of ⁹⁰Sr by natural and synthetic zeolites 
    Lonin, A.Yu.; Krasnopyorova, A.P. (Вопросы атомной науки и техники, 2005)
    The paper researches into factors influencing sorption and selective properties of natural zeolite clinoptilolite from the Sokirnitsky deposit of Ukraine and synthetic zeolites in relation to radionuclide ⁹⁰Sr. It also ...
  • Nuclear-analytical and mineralogical principles and techniques for prediction and investigation of the native-pure rare isotope occurrence 
    Valter, A.A.; Storizhko, V.E.; Dikiy, N.P.; Dovbnya, A.N.; Lyashko, Yu.V.; Berlizov, A.N. (Вопросы атомной науки и техники, 2005)
    Combining nuclear microanalytical, mineralogical, crystallochemical and geochemical approaches, the authors analyze a possibility of natural occurrence of enriched or even pure and superpure rare isotopes that can be ...
  • Power release in a subcritical reactor 
    Demchenko, P.O.; Gussev, Ye.V.; Nikolaichuk, L.I. (Вопросы атомной науки и техники, 2005)
    Numerical simulation results of power release in a subcritical reactor in which the neutron field is generated under bombardment of an actinide target by a relativistic proton beam are given.
  • Study of one-zone subcritical amplifiers of neutron flux involving enriched uranium 
    Babenko, V.A.; Gulik, V.I.; Jenkovszky, L.L.; Pavlovich, V.N.; Pupirina, E.A. (Вопросы атомной науки и техники, 2005)
    We examine the main aspects of the construction of subcritical systems able to multiply neutrons from the external source with emphasis on the choice of the neutron source and optimization of the parameters of the subcritical ...
  • Study of self-organizing regime of nuclear burning wave in fast reactor 
    Fomin, S.P.; Mel’nik, Yu.P.; Pilipenko, V.V.; Shul’ga, N.F. (Вопросы атомной науки и техники, 2005)
    An approach for description of the space-time evolution of self-organizing nuclear burning wave regime in a critical fast neutron reactor has been developed in the effective multigroup approximation. It is based on solving ...
  • Study of the radiochemical and thermal conversions mechanism in products of processing of grapes 
    Dikiy, N.P.; Dovbnya, A.N.; Kutovoy, V.A.; Kutovoy, S.V.; Medvedeva, E.P.; Medvedev, D.V.; Borisenko, N.V. (Вопросы атомной науки и техники, 2005)
    The extraction of biologically active substance was carried out with help of combination of the physical factors: various conditions of temperature (40, 50, 60°С) and pressure of vacuum drying (8, 14, 16 mm Hg), and also ...
