Piping carries water from the condenser to the heat exchanger, where it is turned into steam.

steam outlet click to hear

Water that has been vaporized in the carbon dioxide is carried to the turbine to produce electricity.

blower click to hear

Device that circulates carbon dioxide in the reactor core.
