Abstract (en)
[origin: US4498426A] The invention relates to a superheated steam generator comprising a bank of U-tubes. It comprises a water drum (1) and a secondary casing (14) which are welded one on each side of the tube plate (5) and a bank of tubes (6) fixed on the tube plate (5) and contained in a casing (12) disposed inside the secondary casing (14) and forming an annular space (15) lying between the casings (12 and 14). Above the tube bank casing (12) a free space (25) is provided inside the secondary casing (14). This free space (25) constitutes a reserve of feed water in communication with the annular space (18). The water capacity thus constituted can be fed by at least one supply means (26). The invention is particularly applicable to pressurized-water nuclear reactors.
