Abstract

PURPOSE: To provide a guide tube structure in the flared tube with increase of change of neutron absorbent to increase the control worth of fuel control rod.
CONSTITUTION: A spacer pad 6 is provided for the external side of cylindrical flared tube 2 having both structures of flared tube and guide tube. The protection tube 3 installed in the flared tube 2 contains neutron absorbent 4 which is filled in the cladding tube 5, enabling the charge amount thereof to increase to the amount of guide tube by improving the control worth. Further, the cylindrical flared tube allows to manufacture with ease and improve the dimension precision.
