The provided illustration outlines the process of producing steam involving a gas-cooled nuclear reactor.
Overall, the process consists of a reactor and a heat exchanger. The reactor is placed inside a pressure vessel surrounded by concrete radiation shielding and is used to create hot gas to pass through the heat exchanger.
In detail, the internal structure of the reactor consists of uranium fuel elements, confined by graphite moderators and topped by charging tubes for loading fuel elements and boron control rods. The hot gas generated from the reactor passes through the duct to enter the heat exchanger which occurs outside the concrete radiation shielding.
Simultaneously, the heat exchanger operates as follows: In the heat exchanger, the inlet pipe brings the water to heat it into steam and lets it pass through the turbo alternator. Meanwhile, the hot gas sinks to the bottom, passing the gas blower through a cool duct to enter back into the reactor, thus protecting the steamer from getting hot while at the same time running an uninterrupted continuous process of steam generation.
