Schroeder, H J

A description is given of a steam generator for a pressurized-water coolant nuclear reactor which is of the type having a vertical housing with its lower portion closed by a horizontal tube sheet in which the inlet and outlet legs of an inverted U-shaped tube bundle are mounted, one forming an inlet leg and the other forming an outlet leg for the pressurized-water coolant circulated via the tube bundle and the reactor. The tube bundle is peripherally enclosed by a vertical shell forming a feed-water descent space between it and the housing with this space adjacently above the tube sheet peripherally opening to the latter for radially inwardly directed feed-water flow thereover through the interspaced tubes of the tube bundle legs and upward flow through the latter to generate steam in the housing.
