Nuclear reactor control rod with SIC fiber reinforced structure

A nuclear reactor control rod comprising:

• a plurality of wing sections arranged radially around an axis extending in vertical direction in such a way as to be disposed with spaces therebetween in a circumferential direction, each of the wing sections being a flat plate spreading in a direction of the axis and in a radial direction, each of the wing sections including a plurality of storage tubes made of SiC material or SiC-fiber-reinforced SiC composite material, the storage tubes being arranged in parallel with one another in a flat plane, and the storage tubes containing a neutron absorbing member containing a neutron absorbing material, each of the wing sections including a wing surface structural member formed by molding of SiC-fiber-reinforced SiC composite material in such a way as to cover surfaces of the plurality of the storage tubes and formed to have an outward shape of a flat plate;
• and
• a central joint section made of SiC material or SiC-fiber-reinforced SiC composite material, the central joint section bundling the plurality of wing sections together at center, wherein
• the plurality of storage tubes are bundled together with fibers made of SiC or a textile made of SiC.
