carbon dioxide gas coolant click to hear : carbon dioxide gas coolant

Carbon dioxide that recovers the heat from the reactor core and transfers it to the heat exchanger.

feedwater click to hear : feedwater

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

steam outlet click to hear : steam outlet

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

blower click to hear : blower

Device that circulates carbon dioxide in the reactor core.

heat exchanger click to hear : heat exchanger

Tubing system that is submerged in the hot carbon dioxide; here, water is turned into steam to power the turbine.

reactor core click to hear : reactor core

Center section of the nuclear reactor where fission reactions take place.

control rod click to hear : control rod

Tube that contains a neutron-absorbing material (boron, cadmium) that is introduced into the reactor core to control its power.

concrete shielding click to hear : concrete shielding

Concrete structure that holds back radioactive products in the event of an accident.

fueling machine click to hear : fueling machine

Remote-controlled device that inserts new fuel into the reactor.

fuel: natural uranium click to hear : fuel: natural uranium

Natural uranium: fuel extracted from mines; it consists of a mixture of three uranium isotopes (uranium-234, -235 and -238).

coolant: carbon dioxide click to hear : coolant: carbon dioxide

Carbon dioxide: gas that is heavier than air and is produced by burning graphite.

moderator: graphite click to hear : moderator: graphite

Moderator: medium that slows the speed of the neutrons to maintain a continuous chain reaction.
