    摘要: A feedring for use with an axial flow preheat steam generator which utilizes a double wrapper to direct feedwater flow to the cold leg tube bundle region. The feedring is positioned directly over the double wrapper and includes a plurality of standpipes spaced circumferentially along the feedring. The standpipes respectively extend vertically from a lower portion of an interior of the feedring upward through the interior of the feedring. The standpipes have a feedwater intake in the upper portion of the feedring to minimize the potential for vapor formation and bubble collapse water hammer. The components of the standpipe are arranged to minimize the transmission of entrained loose parts from traveling with the feedwater to the tube bundle. A feedwater discharge is provided at the exit of the standpipe at or below the bottom of the feedring, for evenly distributing the feedwater into the double wrapper downcomer.

    摘要: A method and apparatus are disclosed for substantially eliminating flow induced vibrations of the flow tubes of a steam generator in the U-bend region. Antivibration bars are provided between columns of flow tubes in the U-bend region which are contoured on one side to correspond with the exact as-built and as-bent diameter of the tubes as located within the tube bundle. Measurements of the actual flow tube diameters are made and recorded and stored either on tape or in a computer which is then used to control a numerically operated machine which configures or machines cutouts in the antivibration bars to precisely correspond with the respective measured diameters of the flow tubes. Only one side of the antivibration bars need to be machined because of the flexibility of the flow tubes which allow the positioning of the other side of the flow tubes along a flat plane.

    摘要: A tube support plate is disclosed for supporting a plurality of tubes with reduced vibration in a nuclear steam generator. The support plate has a plurality of holes disposed therethrough in a regular array. Each hole has an axis, an interior surface and a plurality of lands supported on the interior surface and extending towards the axis. The support plate has a given thickness as taken along the hole axis, and each of the lands has a tapered surface for facilitating tube insertion. The method of forming the tube support plate comprises a first step of forming each of the holes through the support plate with a first cylindrical portion of a first diameter and a second cylindrical portion of a second diameter less than the first diameter. Next, portions of the second cylindrical portion are removed in a second step to form a plurality of lands having exposed ends supporting a tube within the hole.
