The illustration describes a procedure of steam generation with the help of gas cooled nuclear reactor.
Overall, reactor and heat exchangers are the essential components of steam production by nuclear energy, where both works simultaneously to keep reactor from overheating.
To begin with, a gas cooled nuclear consists of the reactor itself and heat exchanger. The reactor incorporates a pressure vessel which is covered with a concrete radiation shielding. the vessel, there are four Graphite moderators, each of them containing Uranium fuel element and topped by charged tubes for loading fuel elements. Additionally, each fuel elements are attached to a Boron rod control. The hot gasses are produced by detaching the Boron control rod from the fuel element.
Furthermore, from the reactor the hot gas flows through a duct into the heat exchanger, where steam is generated in a secondary loop. Here, water is fed into pipe by a water circulator, which is heated to produce steam and this steam flows out to turbo alternator. Meanwhile, the hot gases sink to the bottom of heat exchanger and passes from gas blower. The gas blower pushes cool gas into reactor, where it is heated by fuel elements. Hence, process continues
