The invention belongs to the technical field of nuclear reactor design, and particularly relates to a reactor core arrangement and component arrangement of a metal-cooled reactor containing a solid moderator, which comprises the following steps: the reactor core comprises a core active area with a hexagonal structure, a coaming arranged at the outer layer of the core active area, a coolant arranged between the inner layer of the coaming and the outer layer of the core active area, a plurality of fuel rods and a toxic material arranged in the core active area; the poison material has a thermal neutron absorption peak in the interval of 0.1 to 1 eV. The reactor core arrangement and the fuel assembly arrangement of the metal-cooled reactor containing the solid moderator, which are designed by the invention, can enhance the reactor core temperature negative feedback of the metal-cooled reactor containing the solid moderator and ensure the safety of the reactor core of the metal-cooled reactor. |
