describe three risks or disadvantages of nuclear power.

Brief Explanations:

1. Radioactive waste: Nuclear power generates highly - radioactive waste that remains hazardous for long periods, difficult to dispose of safely.
2. Meltdown risk: A nuclear reactor meltdown can release large amounts of radioactive material into the environment, causing widespread contamination and health risks.
3. Proliferation concerns: The technology and materials used in nuclear power can potentially be diverted for nuclear weapons production, posing a threat to global security.

Answer:

1. Radioactive waste disposal issues.
2. Risk of reactor meltdown.
3. Nuclear proliferation concerns.
