The diagram illustrates how gas cooled nuclear reactor is utilized to create steam
Overall, the diagram shows the sectional drawing of the reactor with every component labled, and the direction of water and steam reperesented by arrows.
The reactor is a cylinderical object that is named pressure vessel surrounded by a rectangular concrete radiation shielding. On the shield has charge tubes which are used for loading fuel elements, and a road going straight to the inside of pressure vessel. Inside the vessel there are graphite moderators and uranium fuel elements which are used to heat up cold water.
The reactor is connected by tubes to a heat exchanger, where cold water enters and steam comes out on the other side. The cool water enters this section by entering a water circulator, enabling cool gas to get into the duct and a gas blower before entering the vessle. In the pressure vessel the gas is heated up and exits through a duct at the top creating a steam that goes to a turbo-alternator.
