Abstract (en)

[origin: EP2814039A1] The water supply tube for steam generator includes an insert tube portion (21) inserted in a penetration hole (112) of a shell member and a generator internal tube portion (22) connected to the insert tube portion. The generator internal tube portion includes a tubular passage and an effluence tube (25) allowing effluence of cooling water in the tubular passage to a space (40) in a steam generator. The tubular passage includes a first tilted portion (24c) in which a side having a greater distance from the insert tube portion along a flow direction is located vertically higher than a side having a smaller distance from the insert tube portion and a second tilted portion which is located with a greater distance from the insert tube portion than the first tilted portion. In the second tilted portion, a side having a greater distance from the insert tube portion along the flow direction is located vertically lower than a side having a smaller distance from the insert tube portion. In at least a portion of a section, along the flow direction, of the tubular passage (234a) between the first tilted portion and the second tilted portion, a bottom end (234b) of a cross section of the tubular passage is arranged vertically higher than a horizontal plane (30) including a top end (21a) of an inner wall surface of the insert tube portion at a connection between the insert tube portion and the generator internal tube portion.
