Abstract
The flow distribution baffle (,) is placed inside the bundle wrapper (,) of the steam generator, at its lower part,-near the steam generator tube plate. Passing through the flow distribution baffle (,) are openings (,) for the passage of tubes of the steam generator bundle and feedwater. The flow distribution baffle (,) comprises a central zone (,) of more or less circular shape with, as its axis, the axis of the steam generator and a radius (R,) smaller than 40% of the internal radius (R) of the bundle wrapper (,), and a more or less annular peripheral zone between the central zone and the outer edge of the flow distribution baffle (,). In the central zone (,) the openings (,) for the passage of tubes and feedwater in the flow distribution baffle have a cross section (S,), the cross-sectional area of which is greater than the cross-sectional area of the cross section (S,) of the openings (,) for the passage of tubes and feedwater in the peripheral zone. The total surface area for the passage of feedwater in the peripheral zone (,) is greater than the total surface area for the passage of water in the central zone (,).
