Definitions

  • the U-shaped heat exchanger tubes are contained within the secondary side of said steam generators. Each such heat exchanger tube in inverted, with its open ends mounted in the tubesheet and its legs and bent portion extending into the secondary side. A plurality of vertically spaced-apart support plates are provided in the secondary side for laterally supporting the legs of each heat exchanger tube.
  • the legs of the U-shaped heat exchanger tubes extend through bores present in the support plates. Small, annular spaces are present between these heat exchanger tubes and the bores in the support plates and tubesheet through which these tubes extend. These annular spaces are known in the art as "crevice regions".
  • Such an optional conduit is provided when it is desired to circulate the cleaning solution through the bed 74 to remove dissolved, radioactive ionic species from the solution. However, if this mode of operation is desired, it will be necessary to select resins for the ion-exchange columns that will not remove the dissolved cleaning agents present in the solution, but only the radioactive ionic species.
  • An isolation valve 77 is provided in the optional return conduit to isolate the flow of solution through the main conduit from any contact with the resin bed 74 when the bed 74 is not is use.
