The nuclear reactor of graphite board as the core structure includes: Graphite Sheets water and cold stacks (graphite boards are used as deceleration materials and thermal carriers), graphite board gas -cold piles (Graphite Sheets are used as deceleration materials, carbon dioxide or gas are thermal carriers), graphite board high temperature Qi-cooled piles (usually used as a thermal carrier with ghosts, the temperature of the pyrine can reach about 1000 ° C), 나트륨 플레이트 나트륨 반응기 (나트륨은 열 담당자), 흑연 플레이트는 천천히 증식 (U-th 전환).
