The review of the results of research, development and use of nanomaterials in the nuclear-power engineering and technology have been presented. The basic properties of nanostructured materials are given. The prospects for the use of nanomaterials in the nuclear-power engineering, associated with the creation of nanostructured materials and coatings for structural elements of nuclear-power engineering plant and future thermal nuclear reactor to increase hardness and strength characteristics, raising corrosion and radiation resistance have been considered. The radiation-heterogeneous processes of water decomposition zirconium dioxide (n-ZrO2) nanoparticles have been studied. The kinetics of buildup of molecular hydrogen in the radiolytic processes of water decomposition has been examined. The kinetics of molecular hydrogen accumulation at a gamma radiolysis of water on n-ZrO2 surface is investigated. Influence of gamma radiations on n-ZrO2+H2O systems is studied at various temperatures T=373÷673K. Values of rates of molecular hydrogen accumulation at radiation, radiation-thermal and thermal processes are defined. Deposits of thermal and radiation-thermal processes at accumulation of molecular hydrogen in contact of n-ZrO2 with water are revealed.
