Researchers in Russia have developed carbon composite materials for nuclear reactors that maintain structural stability at extreme temperatures of 2,912°F (1,600°C)—far beyond the limits of conventional metals. Key components include a 1,650 mm core support structure and a flexible control system made of 500 mm modular sections, designed to withstand intense heat, radiation, and mechanical stress. These materials are especially relevant for advanced reactors and next-generation nuclear designs.
