By means of a multi-scale modeling, phase diagrams of graphanes, nanoproducts of Hydrogen chemisorption to graphene, were built for the first time; abnormally high contents of vacancies in highly deformed Beryllium at cryogenic electron irradiation were predicted; the priority data of the Generation IV reactors promising materials corrosion tests under electron irradiation in situ supercritical water and oxygen were explained; the surface fractal structure impact on its ion beam sputtering erosion was revealed. The developed material/data science forecast concept was applied to the selection of GenIV high-temperature reactor materials by virtue of outputs of their radiation/corrosion resistance accelerator simulation tests and market prices forecast with risk assessment. The NSC KIPT developed nuclear graphites feasibility for GenIV reactors was proven based on a new radiation-vacancy model of dimensional changes. Within the scope of a novel self-consistent nonlinear non-stationary theory of terahertz gyrotrons, new, ohmic mode selection based, methods of their efficiency upgrade were substantiated: the resonator longitudinal corrugation and the introduction of a coaxial dielectric rod, ceramic coatings and metamaterials. A new environmentally friendly energy-efficient patent-ready process of the nanodisperse Carbon production by high-speed heating at reduced pressure was developed. By this method, an adust nanographite was obtained with a modified crystalline structure and a content of multiwall nanotubes and fullerene-like formations.
