The diagram illustrates a reactor “, ” including two main parts such as the reactor and a heat exchanger.
Overall, this is a cycle system that helps in the production of steam from water.
First of all, the reactor consists of radiation shielding covering a pressure vessel. Inside the pressure vessel contains four graphite moderators and each of them wraps a fuel rod. Two control rods are used to link charge tubes on the top of the radiation shielding. Besides, the reactor is connected to the heat exchanger by two gas ducts. One contains hot gas and the other contains cool gas.
As can be seen “, ” the hot gas from the reactor flows into the heat exchanger. Then, it goes down the bottom of the heat exchanger and transforms into cool gas. Next, the cool gas continues to pass through a gas blower and pump back to the reactor. Meanwhile, water enters fro
m a lower tube and escapes as steam in an upper tube.
