Question

spent nuclear fuel rods are stored in dry casks. what is a major drawback to nuclear energy? only time can reduce the radioactivity of the waste. it produces less pollution. energy can only be produced on sunny days.

Explanation:

Nuclear energy generates radioactive waste. The radioactivity of this waste can only decrease over time, which poses long - term storage and safety challenges. Producing less pollution is an advantage, not a drawback. And nuclear energy production is not dependent on sunny days as it is a non - renewable energy source based on nuclear reactions, not solar energy.

Answer:

Only time can reduce the radioactivity of the waste.
