New cards
Neutron induced fission
This occurs when a heavy nucleus absorbs a neutron causing it to become unstable causing it to split releasing significant energy
2
New cards
Spontaneous fission
Heavy nucleus splits into two lighter nuclei without external stimulation.
3
New cards
Nuclear fission chain reaction
This occurs when a neutrons released during splitting induced another fission event
4
New cards
Control rods
Regulate the reaction rate
5
New cards
