High-Level Nuclear Waste

High-level nuclear waste is highly radioactive material generated from nuclear reactor operations, primarily used fuel rods. It remains dangerous for thousands of years due to its intense radioactivity and heat production. Proper management involves cooling and containment through specialized storage facilities to protect people and the environment. Over time, these wastes decay and become less hazardous, but their long-term disposal requires secure, lasting solutions, such as deep underground repositories. Effective handling and storage are crucial to prevent contamination and ensure safety for both current and future generations.
