Used to slow down fast neutrons as fast neutrons would just bounce off the fuel and fission would not happen
1 of 5
Use of control rods in a nuclear reactor
Control rods absorb excess product neutrons and control the reactions (to give a 1:1 ration of neutrons in and out- one reaction gives only one more reaction)
2 of 5
Use of coolant in a nuclear reactor
The coolant carries the heat energy (produced by the fission) to the heat exchanger (the coolant is usually water)
3 of 5
Use of a heat exchanger in a nuclear reactor
Transfers heat from coolant to another loop of water (this second loop contains heated water which turns to steam and powers the turbine)
4 of 5
Use of a centrifuge
To enrich U235 - centrifuge separates naturally occuring U238 and U235
