Disposal is the placement of waste in a facility designed to isolate waste from the accessible environment without an intention to retrieve the waste, irrespective of whether such isolation permits recovery of waste.

A controlled area is the area outside of a restricted area but within the area whose access is limited by licensed operators. The access, occupancy, and working conditions are controlled for radiation protection purposes.
A controlled area includes the location of a radioactive waste disposal facility, identified by institutional control that is intended to be used for monitoring and surveillance of a disposal facility and to act against or restrict public access, and the subsurface underlying a surface location.
