摘要： PROBLEM TO BE SOLVED: To flatten a nuclear lifetime distribution in the shaft direction of a control rod, and to extend the nuclear lifetime of hafnium. SOLUTION: The control rod includes: blades 1 formed respectively by facing a pair of blade pieces using a hafnium plate as a control rod effective part; a tie cross 4 provided along the control rod center shaft at intervals, for holding four blades 1 crosswise on the cross section; a trap provided on a facing space of the blade pieces, and filled with reactor water; an axial water region 5 provided in a space between locations of the tie cross 4, and filled with the reactor water; and a spacer 2 provided on the facing space of the blade pieces, maintaining the trap, configured such that a neutron absorbing material is increased gradually toward the insertion tip side from the insertion terminal side of the control rod for a nuclear reactor, following a tendency of the nuclear lifetime which becomes shorter gradually toward the insertion tip side from the insertion terminal side of the control rod for the nuclear reactor, and flattening the nuclear lifetime distribution in the shaft direction of the control rod for the nuclear reactor.

摘要： PROBLEM TO BE SOLVED: To provide a control rod for regulating power that makes the average reactivity value over its lifetime equivalent to that of a shut-down control rod, while achieving the mitigation of problems about blade history, reducing the usage of hafnium, and eliminating the non-integrity and difficulties in the manufacture due to welding deformation or mechanical imbalance. SOLUTION: The control rod CR includes: blades 1 made by confronting one piece of blade pieces 10 holding Hf plates 12 whose thickness in at least 1/4 segment is 1.5 to 2.5 mm with each other; a tie cross 4 arranged with a space secured along the shaft of the control rod CR to hold four blades 1 so that its cross section can be cruciform; a trap 13 arranged in a space between the confronted blade pieces 10 and filled with reactor water; water windows 3 arranged in at least 1/4 segment of each of the blade pieces 10, and forming partial hafnium loss sections; and a shaft center water region 5 arranged in a space between locations of the tie cross 4 with the shaft center water width CW of 10 to 40 mm in at least 1/4 segment of an effective part of the control rod CR.
