Question

Quizplus · Accepted Answer

The smallest amount of radioactive material that will support a self-sustained fission reaction is called the critical mass. This is the minimum amount of material required for a nuclear chain reaction to occur. When the amount of material is below the critical mass, it is referred to as a subcritical mass, and when it is above the critical mass, it is referred to as a supercritical mass. The moderator is a material that slows down the neutrons in a nuclear reactor, and molar mass is a term related to chemistry.
