Circulating water-cooling to Cattenom nuclear plant (PWR 44 1300 MWe) is provided by four natural draft crossflow cooling towers. The antifreezing system uses mechanical shutters, completed by the icing of a wire grid at the bottom of the air inlet. The information gathered last winter does not indicate serious problems. It should now be possible to modulate the shutter position in order to optimize the cold-water temperature.
