Abstract

PURPOSE: To control the pressure fluctuation of cooling water, by providing a pipe connecting an upward flow and a downward flow of the cooler, and also a stable starting valve which is opened in case when the quantity of water required for the cooler is a little in said pipe.
CONSTITUTION: The upward flow side of the cooler group 8 attached to each apparatus, which is a master pipe for feeding cooling water 14, and the downward flow side of the cooler group 8, which is a master pipe for returning cooling water are connected by a stable starting pipe 16, and a stable starting valve 36 is provided around its center. When the main turbine and the generator are stopped, the temperature control valves 33aW33c of each cooler are all closed, but in this case, the stable starting valve 36 is ready for opening, and the pressure fluctuation of cooling water can be controlled to the minimum so as to continue the operation in safety by making cooling water of the cooling water feed master pipe 14 flow into the cooling water return master pipe 15 through the stable starting pipe 16.
