A nuclear reactor is a device used to initiate and control a sustained nuclear chain reaction. It is commonly utilized for generating electricity and for various research purposes.
5 Must Know Facts For Your Next Test
Nuclear reactors use fuel rods, typically made of uranium-235 or plutonium-239, to sustain the chain reaction.
Control rods made of materials like cadmium or boron are used to absorb neutrons and regulate the reaction rate.
Moderators such as water or graphite slow down fast neutrons, making the chain reaction more efficient.
The heat generated from the fission process in the reactor core is used to produce steam that drives turbines for electricity generation.
Nuclear reactors can produce both low-level and high-level radioactive waste that requires careful handling and disposal.
