The core ignition structure is offered, which ensures suppression of initial excessive growth of neutrons flux and of essential variations of FR power. The main working parameters of the studied FR, acceptable to practical use, are found. A temperature behaviour of an effective diffusivity of helium in model BCC and FCC alloys in conditions of a neutron exposure at temperatures from 300С to 900С is studied based on kinetic model of reaction rate theory with the use of ab initio simulation. It is shown that the crystal structure essentially influences the integral transfer of atomic helium. The rate of heterogeneous bubble nucleation in the metal coolant based on the modified Gibbs approach is found and the comparison with outcomes of the classical nucleation theory is done.
