Nuclear Energy and Waste Management

In 2019, there were 444 nuclear reactors operating globally. While some scientists advocate for their closure due to risks and waste disposal challenges, others highlight their clean energy potential. Low-level radioactive waste is manageable, but high-level waste disposal remains complex. A deep repository in Germany exemplifies long-term storage solutions. The video emphasizes weighing energy benefits against environmental risks, stressing the importance of informed energy choices.
