Auxiliary feedwater is a backup water supply system found in pressurized water reactor nuclear power plants. This system, sometimes known as Emergency feedwater, can be used during shutdowns, including accident conditions, and sometimes during startup. It works by pumping water to the steam generators from reserve tanks or a larger body of water (for example lake, river, or ocean) to remove decay heat from the reactor.
