The diagram illustrates the series of stages involved in the process of steam, which uses a gas-cooled reactor.
Overall, the stages have two parts to produce steam: the reactor and the heat exchanger, connected by two pipes. In addition, the reactor has six parts, while the heat changer has only three.
To begin with, the cooled gas is blown into the reactor’s concrete radiation shielding by a gas blower and passes through the pressure vessel. Then, the gas rises near the graphite moderators, which have uranium fuel elements. In the upper part of the graphite moderators, there are boron control rods, and they are connected to charge tubes for loading fuel elements.
Next, the gas passes the reactor when the boron control rods rise. After that, this stage heats the gas, and it moves into the heat exchanger in order to be cooled. The water, which exits when it cools the gas, comes into a water circulator to provide steam to the turbo-alternator.
