Question 9 • *KCPS Physics First (2027)

Which compares the problems associated with radioactive waste created from generating electricity using fusion reactions to waste created from generating electricity using fission reactions?

Answer
A
Although their radioactive wastes are hazardous for the same period of time, fusion reactions produce less waste than fission reactions.
B
The radioactive waste from fusion reactions becomes less hazardous much sooner than the waste from fission reactions.
C
The radioactive waste from fission reactions becomes less hazardous much sooner than the waste from fusion reactions.
D
Although their radioactive wastes are hazardous for the same period of time, fission reactions produce less waste than fusion reactions.

Explanation

Fusion reactions do not produce the same long-lived radioactive fission products created when heavy atoms split. Materials exposed to radiation in a fusion reactor can become radioactive, but they generally become less hazardous much sooner than fission waste. Therefore, choice C is correct.
