Explain why obtaining energy from nuclear fusion reactions is preferable to obtaining energy from nuclear fission reactions. Give two reasons.

(N/A) Obtaining energy from nuclear fusion reactions is preferable to obtaining energy from nuclear fission reactions for the following reasons:
$(i)$ For a given mass of fuel,the energy released during nuclear fusion is significantly greater than the energy released during nuclear fission.
$(ii)$ Nuclear fission produces radioactive waste,which poses a significant challenge for safe disposal and long-term storage. In contrast,nuclear fusion does not produce such hazardous radioactive waste,making it a cleaner and safer alternative.
