[edit] Definition of Decommissioning
Decommission mean to withdraw from service. 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.
[edit] Methods of Decommissioning
[edit] Dismantling
Parts of the reactor are removed or decontaminated soon after the nuclear plant closes,allowing the land to be used for other purposes.
[edit] Safe Storage
The nuclear plant is monitored and radiation is allowed to decay. Then afterwards it is dismantled.
[edit] Entombment
Sealing off radioactive components with concrete and steel. This allows radiation to decay until the land can be used for other purposes.
