固体の核分裂生成物を含む所のPu富化度が６％から９％の範囲のU238を主成分とするアクチニドの酸化物をリニューアル核燃料ペレット（１３２）にし太径被覆管（１４１）の上部に充填し、太径被覆管（１４１）の下部には濃縮度が４％から６％の範囲の濃縮ウランの酸化物からなる濃縮ウラン核燃料ペレット（１３３）を初装荷核燃料全長の５％から１０％の範囲で充填したことを特徴とするリニューアル核燃料棒（１３１）。   An actinide oxide based on U238 with a Pu enrichment in the range of 6% to 9% containing solid fission products is made into a renewed nuclear fuel pellet (132) at the top of the large diameter cladding tube (141). At the bottom of the large-diameter cladding tube (141), enriched uranium nuclear fuel pellets (133) made of oxides of enriched uranium with enrichments ranging from 4% to 6% are placed at 5% to 10% of the total length of the initial loaded nuclear fuel. Renewable nuclear fuel rod (131), characterized by being filled in the range of 中心の固体減速材芯（２０１）を酸化カドミウム中皮（２０２）で覆い外表面をジルカロイ外皮（２０３）で覆ったボイド反応度抑制板（２００）をチャンネルボックス（３５）の制御棒と反対側の１側面に付帯せしめ、制御棒に面する側のチャンネルボックス（３５）の肉厚を増したチャンネルボックス（３５）の内に、
請求項１のリニューアル核燃料棒（１３１）を多数本正方格子状に配列したことを特徴とするリニューアル核燃料集合体（１３０）。
A void reactivity suppression plate (200) having a central solid moderator core (201) covered with a cadmium oxide core (202) and an outer surface covered with a zircaloy shell (203) is opposite to the control rod of the channel box (35). In the channel box (35) which is attached to one side of the channel box and the thickness of the channel box (35) on the side facing the control rod is increased,
A renewal nuclear fuel assembly (130) comprising a plurality of renewal nuclear fuel rods (131) according to claim 1 arranged in a square lattice pattern.
