としたことを特徴とする制御棒要素。In the control rod element, which is made by filling a hollow circular tube with pellets made by sintering a material with a large neutron absorption cross section, the pellet is divided into many pieces along a plane that includes the central axis of the pellet. A control rod element characterized by having a structure in which a thin wire made of a highly ductile material is inserted into the gap to hold the gap between the divided pellets and bring the inner surface of the circular tube and the side surface of the pellet into close contact. .
