PROBLEM TO BE SOLVED: To provide a nuclear fusion reactor blanket which achieves high tritium proliferation performance while maintaining structural soundness of a blanket, and a support structure thereof.SOLUTION: A blanket 12 includes: a body outside wall 18 having an outside wall cylindrical part whose one opening end is closed by an outside wall spherical shell part; a body inside wall 19 having an inside wall cylindrical part whose one opening end is closed by an inside wall spherical shell part while being enclosed by the body outside wall 18, leaving a gap with the inner surface of the body outside wall 18, and having a proliferation material and a multiplication material inside; a flange 21 to which a pipe for supplying and recovering cooling water and a pipe for supplying and recovering emission gas are attached while closing the other opening end of the body 20; and a rib 25 for setting a passage for the cooling water supplied into the gap and recovered which is arranged at least either at a position where the passage of the cooling water on the outer surface of the inside wall spherical shell part is made narrow or at a position where turbulence of the cooling water flowing on the outer surface of the inside wall spherical shell part is caused to be generated.SELECTED DRAWING: Figure 4 【課題】ブランケットの構造的な健全性を維持しつつ、高いトリチウム増殖性能を実現する核融合炉用ブランケット及びその支持構造を提供する。【解決手段】ブランケット１２は、外壁円筒部を有し、外壁円筒部の一方の開口端が外壁球殻部に閉止された筐体外壁１８と、内壁円筒部を有し、内壁円筒部の一方の開口端が内壁球殻部に閉止されるとともに筐体外壁１８の内面と空隙を設けて筐体外壁１８に内包されて、増殖材と増倍材とを内部に備えた筐体内壁１９と、筐体２０の他方の開放端を閉止して、冷却水を供給及び回収する配管及び搬出ガスを供給及び回収する配管が取り付けられたフランジ２１と、空隙に供給され回収される冷却水の流路を設定するリブ２５であって、内壁球殻部の外面上における冷却水の流路を狭くする配置及び内壁球殻部の外面上を流通する冷却水の乱流を発生させる配置の少なくとも一方に配置されるリブ２５と、を備える。【選択図】 図４
