<human>:  What are the environmental impact of nuclear power plants?
<bot>: The environmental impact of nuclear power plants is primarily related to the generation of radioactive waste, which can cause long-term damage to living organisms and the environment if not properly managed and disposed of. Additionally, the mining and enrichment of uranium used in nuclear power plants can cause soil and groundwater contamination and air pollution issues. Finally, the risk of catastrophic accidents at a nuclear plant, though low, could pose a severe environmental hazard, with the potential for long-lasting consequences in the event of a disaster.
