To remove the huge amount of heat energy in a nuclear reactor, ______ is/are used.
- A
Core
- B
Control rods
- C
Shielding
- D
Moderators
- E
Coolants
The heat released by fission in nuclear reactors must be captured and transferred for use in electricity generation. To this end, reactors use coolants that remove heat from the core where the fuel is processed.
The core is the part of the nuclear reactor where the nuclear fuel is contained and fission reactions take place, generating heat. However, it does not remove heat; it is the source of heat.
Control rods are used to manage the rate of the nuclear reaction by absorbing neutrons. They do not play a role in heat removal.
Shielding is used to protect the environment and personnel from radiation exposure, not for heat removal.
Moderators are used to slow down neutrons to sustain the chain reaction, but they do not remove heat from the reactor.
Coolants are fluids or gases that circulate through the reactor core to absorb and transfer the heat generated by nuclear fission, making them essential for heat removal.
