Question

What are the potential problems for nearby water sources when using nuclear energy? Check all that apply.

It contaminates water with radioactive waste.
It adds very hot water to cool water environments.
It creates hazardous conditions for organisms living in the water.
It releases uranium dust.
It requires mining large areas of land.
It uses a resource that becomes scarce during a drought.

Answer 1

Selected:
- It contaminates water with radioactive waste.
- It adds very hot water to cool water environments.
- It creates hazardous conditions for organisms living in the water.
- It uses a resource that becomes scarce during a drought.

Why: Nuclear plants can release radioactive material in accidents or via improper disposal, and routine cooling-water discharges cause thermal pollution that harms aquatic life. Plants also require large volumes of water, so droughts can limit cooling supply and affect operations.

Not selected:
- It releases uranium dust — that is mainly a risk during mining/milling, not normal plant operation, and is not a common direct threat to nearby surface water from the reactor itself.
- It requires mining large areas of land — mining is an environmental issue (and can affect water at mine sites), but it’s not a direct impact on water sources near an operating reactor.
