The diagram below shows the production of steam using a gas-cooled nuclear reactor. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
The given process diagram illustrates the generation of steam by a gas-cooled nuclear reactor.
Overall, the gas cooled nuclear reactor consists of a reactor itself which is covered by concrete radiation shielding and a heat exchanger. It is a continuous process that keeps the reactor from overheating while carrying away the steam and heat from the turbines.
The reactor contains uranium fuel elements which are surrounded by the graphite moderators and topped up with charging tubes for loading the fuel element and boron control rods. The whole reactor is contained in a pressure vessel surrounded by concrete shielding.
From the reactor, the hot gas flows through an upper hot duct of the heat exchanger, which is situated outside the concrete shielding. Following that in the hot gas moving down into the lower duct of the heat exchanger in the meanwhile, there is a pipe brings in water which converted into steam by the help hot gas. Subsequently, the generated steam escapes out to the turbo-alternator, and the hot gas is transformed into cool and sinks to the bottom of the heat exchanger and passes through a gas blower which pushes it into a cool gas duct and back to the reactor.
