Interpretation: To explain neutron moderators and their importance in a nuclear reaction.
Concept Introduction: Nuclear fission can be controlled via two steps that are as follows:
- Neutron moderation
- Neutron absorption
Answer to Problem 20LC
The process that slows down the neutrons is known as neutron moderation and it is necessary as the produced neutrons travel very fast that they can even pass the nucleus without being captured.
Explanation of Solution
The process that slows down the neutrons is known as neutron moderation. This slowing down of neutrons is important so that the neutrons get captured by the reactor fuel and further helps in continuing the reaction chain.
The process of moderation is necessary for the nuclear reaction, as the produced neutrons travel very fast that they can even pass the nucleus without being captured. Thus, this step is important in a nuclear reaction.
