Words and meanings to learn
control rods
are rods that can be inserted into the reactor core to absorb neutrons and slow down or stop the fission chain reaction.
moderator
a material (like water or graphite) used in a nuclear reactor to slow down the fast-moving neutrons, making it easier for them to cause more fission in the fuel.
fission
when the nucleus of a large atom (like uranium) splits into two smaller nuclei, releasing energy.
chain reaction
is a process where each nuclear fission event releases neutrons that cause more fission events, creating a continuous cycle.
reactor core
is the part of a nuclear reactor where the fission happens. It contains the fuel rods (made of uranium), the moderator, and other materials that control the reaction.
