Design and research of chilled water system in electric building in some advanced nuclear power plant

To ensure the normal operation of the main control room, DCS in electrical control cabinet, emergency boron injection system, the medium-pressure and low-pressure safety injection pump, and to ensure the residence of main control room, the equipments and pipes of the electric building chilled water system should be reasonable layout. The paper described the developing process of the chilled water System, and the system function was analyzed in the paper. Through the analysis of the function, safety, operation and economic, etc, the paper completed the layout of the equipments and pipes. It provided a reliable guarantee to the safe operation of the advanced nuclear power plant. (authors)
