摘要： Low temperature water in a low temperature water tank 12 installed outside a reactor pressure vessel 9 is pumped by a high pressure pump 15 and supplied through a conductor 17 under pressure. The supplied water is ejected, as a stream of cold water jet 8, from a nozzle 14 connected to the conductor 17 and introduced into the reactor pressure vessel 9 by a driving mechanism. The stream of cold water jet 8 ejected from the nozzle 14 is directed to impinge against a predetermined position of a core shroud 13 in reactor water 11 filled in the reactor pressure vessel 9 and being at temperature higher than the low temperature water. Then, while continuing to eject the cold water jet 8 from the nozzle 14, the nozzle 14 is moved away from the predetermined position, or the ejection of the cold water jet 8 from the nozzle 14 is stopped, allowing the predetermined position to be heated again with the temperature of the reactor water 11. A thermal shock is thereby applied to the predetermined position for improvement in residual stress of the core shroud 13.

摘要： A preparatory molding roll 4 having a convex push surface 41 is pushed to an outer peripheral surface of a work 1A while the work 1A is chucked by a pair of molds 2 and 3 and is rotated by applying axial propelling force, to bend inward the outer peripheral surface of the work in a radial direction. The work is then chucked by the preparatory molding roll and the upper and lower molds. Next, the preparatory molding roll is moved back and the work is crushed in the axial direction to form a bent portion 1a. A molding roll 5 is pushed to mold the outer shape of the work. A grooved roll 6 is next pushed to the outer peripheral surface of the work and a groove 1b is formed on the outer peripheral surface.
