Chapter 24: Q24.84P (page 1105)

What is the minimum number of neutrons from each fission event that must be absorbed by other nuclei for a chain reaction to be sustained?

Short Answer

Expert verified

The number of neutrons that must be absorbed is one.

Step by step solution

01

To find minimum number of neutrons

In order to sustain the chain reaction, the minimum number of neutrons from each fission event that must be absorbed is ONE.However, in actual fact, two or three neutrons are generally needed to strike a chain reaction because of the loss of neutrons from fissionable material.

Hence The minimum number of neutrons to be absorbed is one.
