Chapter 40, Problem 15A

What happens when U-238 absorbs a neutron?

To determine

The effect on U-238 due to absorbing neutrons.

Explanation of Solution

Introduction:

The chain reaction is the uncontrolled initiation of other fission reactions due to the neutrons from the previous fission reaction.

The necessary condition for the fission reaction is that adequate number of the neutrons must present for the each radioactive material.

The amount of U-238 in the nature is more. So, a greater number of neutrons it requires to initiate the fission reaction. The number of neutrons available for absorbing by U-238 is very less compared to the amount of it and U-238 does not undergo fission reaction.

Conclusion:

Thus, Uranium-238 does not undergo fission reaction by absorbing neutron.
