摘要 |
In a steam generator equipping a nuclear power station and having inverted U-Lubes connected to a tube plate or sheet (12) and surrounded by an inner envelope (26) having a lower flow distribution plate (41) in its bottom part, the space (46) known as a waterway between the tube plate (12), the flow distribution plate (41) and the hot and cold branches of the tubes contains a deflection and purging box (44). The latter extends over the entire length of the waterway and in height up to the upper edge of the lower envelope (26). It is provided on its lower face with purging orifices (50) and fulfils both a deflection function and a secondary fluid drainage function in the vicinity of the tube plate (12).
