Example Embodiment
[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0030] like figure 1 and figure 2 As shown, an open grid air-cooled space nuclear reactor core of the present invention includes a core active area 16, a core barrel 4 wrapped around the periphery of the core active area, and a core barrel 4 wrapped on the outside of the core barrel 4. There are two reflective layers (inner reflective layer 7 and outer reflective layer 5 ); the core active area 16 is composed of a plurality of fuel rods 2 and a plurality of control rods 3 . The fuel rods 2 and control rods 3 are arranged in a triangular or rectangular grid, forming an open space for the coolant to flow.
[0031] like image 3 and Figure 4 As shown, the fuel rod 2 includes a fuel pellet 12, a fuel rod gas gap 13-1 and a fuel rod cladding 14-1 in sequence from the inside to the outside.
[0032] like Figure 5 and Image 6 As shown, the control rod 3 i...
