Topic: Chap 5- Nuclear Power Plants

Difficulty: Medium

Following are the types:-

1) Fast reactors

In these reactors, the fission is effected by fast neutrons without any use of moderators.

2) Thermal reactors

In these reactors, the fast neutrons are slowed with the use of moderators. The slow neutrons are absorbed by the fissionable fuel and chain reaction is maintained. The moderator is the most essential component in these reactors.
