Graphite is used as moderator to slow neutron velocity and carbonic acid gas is used as a coolant, to remove heat. The heated carbonic acid gas is then transferred to the heat exchanger, where water is converted into steam, which in turn, drives the turbine to generate electricity. Tokai Power station is a gas-cooled reactor, referred to as an Improved Calder Hall type. Steam generated by the heat from nuclear fission drives the turbine to produce electricity. The steam then moves to the condenser, where it is cooled with seawater and recycled into the reactor.
