DECON - soon after the nuclear facility closes, equipment, structures, and portions of the facility containing  radioactive contaminants    
are removed or decontaminated to a level that permits release of the property and termination of the NRC license.         
SAFSTOR - often considered "delayed DECON," a nuclear facility is maintained and monitored in a condition that allows     
the radioactivity to decay; afterwards, it is dismantled.                 
ENTOMB - radioactive contaminants are encased in a structurally long-lived material, such as concrete. The entombment structure is appropriately
maintained, and continued surveillance is carried out until the radioactivity decays to a level permitting unrestricted release of the property.
