The program complex for multiscale computer simulation of radiation impact on materials properties has been created. The methodology of its application to computational support of the NSC KIPT experimental R&D on radiation materials science of alternative nuclear power systems of Generation IV and production of novel functional materials has been developed and worked out. By means of the multiscale modeling, phase diagrams of graphane, a new functional graphene-based nanomaterial, have been obtained for the first time. Structural "order-disorder" phase transition in graphanes has been revealed and its macroscopic thermodynamical description has been given. The information technology and the decision making support system for resource saving economically sound choice of Generation IV high-temperature gas-cooled reactors (HTGR) materials were developed, and applied to the components cost prediction of their vessel and steam generator materials to the horizon of year 2030 with math-statistical assessment of the forecast risk. The non-linear non-stationary multi-mode self-consistent theory of Terahertz gyrotron has been built along with an appropriate computer code for its parameters optimization taking into account ohmic losses in cavity walls and conversion of modes. This resulted in revealing of a supplementary mechanism of the device output power reduction due to the ohmic losses driven decrease of a resonator Q factor, and significantly improved the agreement of the calculated output power and efficiency of Terahertz gyrotrons with the experimental data available. An upgrade of the thermal-vacuum facility for development and implementation of a new method of production of nanographites by means of continuous vacuum treatment of a carbon material has been completed. First experiments at the upgraded facility have demonstrated the thermal-vacuum method's capability of obtainment of fine-disperse carbon with noticeable nanofraction.
