Nuclear decommissioning is the process of safely closing and dismantling a nuclear power plant after it has reached the end of its operational life. This involves removing radioactive materials, securing the site, and ensuring that the environment is protected from contamination. The goal is to return the site to a state where it can be used for other purposes or left in a safe condition. The decommissioning process typically includes several stages, such as planning, decontamination, and dismantling. Regulatory agencies oversee these activities to ensure compliance with safety standards. Proper decommissioning is essential for public health and environmental safety.
