Abstract

PURPOSE: Even in an accident, such as a complete functional breakdown for the whole feed water station, specifically organized is a special arrangement under which a feed water supply can be continued, so that the outpouring of the high-temperature water in a feed water pump to the outside can be prevented in order to prevent the atmospheric deterioration from happening.
