【実用新案登録請求の範囲】[Scope of utility model registration request] 被覆管に収められた中性子吸収体をブレードに直線状に
収容した十字状構造の原子炉用制御棒において、前記各
ブレードの先端部に位置する吊性子吸収体の被覆管の肉
厚をプレート根元側に位置する被覆管の肉厚よりも厚く
し、しかも先端部の中性子吸収体濃度を根元部より高く
したことを特徴とする原子炉用制御棒。In a nuclear reactor control rod with a cross-shaped structure in which a neutron absorber housed in a cladding tube is linearly housed in a blade, the wall thickness of the cladding tube of the hanger absorber located at the tip of each blade is defined as the thickness of the cladding tube at the base of the plate. A control rod for a nuclear reactor, characterized in that the wall thickness is thicker than that of the cladding tube located on the side, and the neutron absorber concentration at the tip is higher than that at the base.
