Fission And Fusion Flashcards
1
Q
How does nuclear fission work?
A
A large nucleus (uranium-235 or plutonium-239) absorbs a neutron and then splits into two smaller nuclei
2
Q
What is released from nuclear fission?
A
In the process of nuclear fission 2 or 3 neutrons are released along with some energy
3
Q
What is a controlled chain reaction?
A
A controlled chain reaction allows only one neutron from each fission to cause another fission.
4
Q
Where do controlled chain reactions happen?
A
Nuclear power stations
5
Q
Where does the fission process take place?
A
Uranium fuel rods in nuclear reactors
6
