Decommissioning refers to the process of safely shutting down and dismantling facilities or equipment that are no longer in use. This often applies to structures like nuclear power plants, oil rigs, or military bases. The goal is to minimize environmental impact and ensure public safety by properly managing hazardous materials and waste. The decommissioning process typically involves several steps, including planning, removal of hazardous substances, dismantling structures, and restoring the site. Regulatory agencies oversee these activities to ensure compliance with safety and environmental standards, making decommissioning a critical aspect of responsible facility management.
