摘要： PROBLEM TO BE SOLVED: To provide an arrangement of a welding part and the groove shape of a tie rod most suitable for utilizing laser welding technology of a control rod, in a boiling water reactor. SOLUTION: The control rod including four fins 8 of a bar-shaped tie rod 1 welded in a state that a U-shaped cross section of a projecting part 23 for welding of a sheath 2 sandwiches the four fins, has an uneven part formed on the groove shape of a tip end part of the four fins 8 or changes the arrangement of the welding parts 9 of the four fins. Thereby, welding metal is continued on the uneven part by an uneven shape of a tip end surface of the fin, a clearance between a projecting part 23 and an overlapped margin 10 is sealed, and clearance corrosion can be prevented. Heat input in welding can be dispersed by a change in the arrangement of the welding part, and deformation of the tie rod and the sheath can be reduced. Therefore, a sound control rod which suppresses deformation resulting from welding can be obtained.
