In an energy context it normally refers to nuclear decommissioning -- removing a [[nuclear energy]] plant from service. Because of the possible presence of radioactive or fissile material in a nuclear facility, special precautions are required.\n\n== Methods ==\n\n=== Dismantling ===\n\nParts of the reactor are removed or decontaminated soon after the nuclear plant closes,allowing the land to be used for other purposes.\n\n=== Safe Storage ===\n\nThe nuclear plant is monitored and radiation is allowed to decay. Then afterwards it is dismantled.\n\n=== Entombment ===\n\nSealing off radioactive components with concrete and steel. This allows radiation to decay until the land can be used for other purposes.\n\n== See also ==\n\n* [[Wikipedia:Nuclear decommissioning]]\n\n{{Page data\n| license = CC-BY-SA-3.0\n}}\n\n[[Category:PH261]]\n[[Category:Energy]]"}
