    Borts, B.V.; Gann, V.V.; Zelinsky, A.Yu.; Parkhomenko, A.A.; Vanzha, A.F.; Marchenko, Yu.A.; Patochkin, I.V. (Вопросы атомной науки и техники, 2022)
    The burnup of uranium target plates of the NSC KIPT neutron source was studied. An analysis of experimental work on the effect of neutron irradiation on the strength and plastic properties of uranium and U-Mo alloys under ...
  • Computer simulation of fission wave propagation in subcritical assembly using code MCNP 
    Gann, A.V.; Gann, V.V. (Вопросы атомной науки и техники, 2009)
    Computer simulation of neutron kinetics in the electron accelerator driven subcritical assembly was carried out using the code MCNP. Propagation of fission wave along the fuel rod to both sides of the neutron source after ...
  • Critical sizes of standing nuclear burning waves in systems with external control 
    Leleko, Yu.Ya.; Gann, V.V. (Вопросы атомной науки и техники, 2020)
    The theory of standing waves of nuclear combustion in reactors having a flat, cylindrical or spherical shape of the core is developed. A spherical standing wave occurs when nuclear burning propagates radially from the ...
  • Generation of MeV -energy protons in WWER reactor core 
    Gann, A.V.; Gann, V.V. (Вопросы атомной науки и техники, 2009)
    The spectrum of fast protons, generated by fast neutrons of WWER-1000 reactor core in water, has been calculated using the Monte Carlo method. The main mechanism of fast proton generation in the moderator is found to ...
  • Investigation of the energy deposition profile in NaCl under electron irradiation 
    Gann, V.V.; den Hartog, H.W.; Vainshtein, D.I. (Вопросы атомной науки и техники, 2004)
    We have proposed a new model for the calculation of the absorbed dose profile in a thick target under 0.1…3 MeV electron irradiation. The build-up phenomenon is shown to increase the maximum of the energy deposition profile ...
  • Nuclear reactor on cylindrical standing burning wave with an external negative reactivity feedback 
    Leleko, Yu.Y.; Gann, V.V.; Gann, A.V. (Вопросы атомной науки и техники, 2017)
    Neutron kinetics of nuclear burning wave in moving incompressible neutron-multiplying medium in the pres-ence of nuclear reactions is developed. A cylindrical reactor is considered, where the burning wave moves radially ...

    In this work, the rate of radiation damage production in a uranium target of the neutron source at NSC KIPT under electrons irradiation with an energy of 100 MeV was estimated. The contribution of elastic and inelastic ...
  • Spherical standing burning wave with external automatic reactivity control 
    Leleko, Yu.Y.; Gann, V.V.; Gann, A.V. (Вопросы атомной науки и техники, 2019)
    Neutron kinetics of a nuclear burning wave in moving incompressible neutron-multiplying medium in the presence of nuclear reactions is developed. A spherical reactor is considered, where fuel moves with acceleration to the ...
  • Static neutronic calculation of a fusion neutron source 
    Chernitskiy, S.V.; Gann, V.V.; Ågren, O. (Вопросы атомной науки и техники, 2014)
    The MCNPX numerical code has been used to model a fusion neutron source based on a combined stellarator-mirror trap. Calculation results for the neutron flux and spectrum inside the first wall are presented. Heat load and ...
