Nuclear Reactor Components and Function

Moderator: This component slows down fast-moving neutrons, making them more likely to cause fission in uranium atoms. Common moderators include water, graphite, and heavy water.
Primary Function: The primary function of a nuclear reactor is to control nuclear fission to produce heat energy. This heat is used to generate steam, which drives turbines to produce electricity.
Control Rods: Control rods are made of neutron-absorbing materials, like boron or cadmium. They are inserted into the reactor core to absorb neutrons and regulate the rate of nuclear reactions. They are used to control the power output of the reactor.
Fuel: Enriched uranium is the most common fuel used in nuclear reactors. This fuel contains a higher percentage of uranium-235, the fissile isotope.
Heat Exchanger: The heat exchanger transfers heat from the reactor core to a separate loop containing water, producing steam. This steam is then used to drive turbines.
