Abstract
In a steam generator or boiler used in a nuclear reactor, the secondary water is supplied via at least one pipe (48) issuing directly into the bottom of an annular recirculation space (32) formed between the outer envelope (10) and an inner envelope (26) surrounding inverted U-tubes (24), on the side of the cold branches of the tubes. A perforated collar or flange (56) placed in the annular space (32), above the pipe (48), produces a pressure drop or flow limitation preventing the rise of the feed water and controls the circumferential distribution of the recirculation water, which drops from the separators (28).
