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.

Explanation:

• It contaminates water with radioactive waste: Nuclear energy production generates radioactive waste. If not properly managed, this waste can leach into water sources, making the water unsafe for use and harmful to aquatic life.
• It adds very hot water to cool water environments: Nuclear power plants use water for cooling. The heated water (thermal pollution) when released back can change the temperature of the water body. Many aquatic organisms are sensitive to temperature changes, which can disrupt their metabolic processes, reproduction, and survival.
• It creates hazardous conditions for organisms living in the water: Both radioactive contamination (from point 1) and thermal pollution (from point 2) create hazardous conditions. Radioactive substances can cause genetic mutations and cell damage in aquatic organisms. Thermal changes can lead to oxygen depletion (warmer water holds less oxygen) and stress on organisms.

• It releases uranium dust: Uranium dust release is more related to the mining and milling of uranium ore (the fuel for nuclear reactors) rather than the direct impact on water sources from using nuclear energy (i.e., operating the reactor). It is more of a mining - related air and land pollution issue in the uranium supply chain, not a direct water - source problem from nuclear energy use.
• It requires mining large areas of land: This is an environmental impact related to land use (habitat destruction, soil erosion etc.) for uranium mining, not a direct impact on water sources from the use of nuclear energy.
• It uses a resource that becomes scarce during a drought: Nuclear power plants use water for cooling. However, during a drought, many power plants (not just nuclear, but also coal - fired which use water for cooling too) face water scarcity issues. But this is more of a general water - resource - management - during - drought issue rather than a unique “problem” caused by nuclear energy to water sources.

Answer:

• 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.
