WebJan 23, 2024 · The graphite serves as the moderator. Fresh fuel is added at the top of the reactor and the spent fuel removed from the bottom, allowing continuous operation. The helium coolant is maintained at high temperatures and pressures, which increases the efficiency of heat transfer and power production. WebThe surplus production reactors, which are graphite-moderated and water-cooled, were used to produce plutonium and other special nuclear materials. As shown in Figure 1, each reactor building contains inner and outer rod rooms, laboratory areas, fuel storage basins, and the reactor block.
