Answer :
Final answer:
Nuclear energy's major drawback is the production of long-lasting radioactive waste, posing environmental and security risks, along with the threat of reactor accidents.
Explanation:
One major drawback to nuclear energy is the production of high-level radioactive waste that remains dangerous for thousands of years. This waste needs careful disposal to prevent environmental damage and potential misuse for nuclear weapons.
Radiation from nuclear waste can harm living organisms and poses a significant challenge in terms of long-term storage and management, increasing the overall cost of nuclear power.
Nuclear accidents such as reactor meltdowns also present catastrophic risks and concerns surrounding the safety of utilizing nuclear energy as a power source.
