Abstract

Steam generators are used in pressurized water-cooled nuclear reactors for generating steam which issues from the generator through a large bore steam outlet. Heat-exchange tubes through which feed water flows are surrounded by hot cooling water from the reactor. The tubes must be capable of being inspected and repaired. To simplify inspection and repair, the tubes are U-shaped and each end of each tube is connected upwardly to a tube plate in the steam generator, whereby each end of each tube can be reached in a simple manner through an outgoing steam outlet.
