The research methods combine experimental methods of metallography, optical and electron microscopy with the calculations of finite element methods, technical thermohydraulics and molecular dynamics. The solution of thermo-hydraulic equations was used to select the optimal test modes. Molecular-dynamic modeling investigates the heterogeneity of the atomic scale of the supercritical fluid, which reflects the manifestations of continuous gas-liquid transitions. The four-channel irradiation chamber with 20 controlled tensile samples of austenitic 12X18H10T steel has passed successful 500-hour tests in the environment of convection flow of subcritical and supercritical water flow under accelerated electrons with energy 10 MeV irradiation. The dependence of the macroscopic indices of the corrosion of the samples on the electron fluence and temperature was found. The scientific and practical results of the development are submitted in 7 publications. The patent of Ukraine on technology of research of corrosion resistance of samples of structural material under irradiation was obtained. The results currently obtained are unmatched in the world.  Product Description popup.authors popup.nrat_date 2020-04-02 Close
