Chapter 24, Problem 64A

Interpretation Introduction

Interpretation:

The reason for the fuel of nuclear reactor to be enriched needsto be explained.

Concept introduction:

Nuclear fission forms energy that is achieved by nuclear reactors. This energy is used to form electricity at nuclear power plants.

Explanation of Solution

U-238 is found in nature that contains 92 protons and 146 neutrons. It does not split easily but U-235 splits easily. When hit by a neutron, U-235 atom undergo fission. Fuel that is used in nuclear power plants is enriched to contain 3% uranium-235. Amount of uranium necessary to sustain a chain reaction is called enriched uranium.

Conclusion

Government enriches natural uranium and they artificially magnify the abundance of radioisotope needed.
