Chapter 40, Problem 24A

To determine

The reason for the fusion reactors not presents day realities like fission reactor.

Explanation of Solution

Introduction:

The nuclear fusion is the integration of two light nuclei, and nuclear fission is the disintegration of the heavy nuclei to lighter ones.

Nuclear fusion occurs at a very high temperature, and this requires a high amount of input energy. The high temperatures are achievable but the temperature at which the fusion of nuclei occurs, metal and devices melts and vaporize at that temperature.

Conclusion:

Thus, the fusion reactors are not present-day reality because fusion requires high energy input and reactors melts and vaporizes at high temperature.
