Question
What is fired into a nucleus to cause nuclear fission?
Solution
Nuclear fission is typically initiated by firing a neutron into a nucleus. Here are the steps:
-
A free neutron is accelerated and directed towards a heavy nucleus such as uranium-235 or plutonium-239.
-
The heavy nucleus captures the incoming neutron, becoming unstable in the process.
-
This instability causes the heavy nucleus to split into two or more smaller nuclei, releasing a large amount of energy in the process.
-
In addition to the smaller nuclei, more free neutrons are also released. These neutrons can then cause further fission reactions, leading to a chain reaction if not controlled.
-
The energy released in the fission process is what is harnessed in nuclear power plants to produce electricity.
