Although housed in DOE (or its precursors), NEST has always relied upon the Defense Department to perform the actual render safe procedures in a nuclear incident.
The FBI, however, has always looked to DOD to perform the render safe procedures on a nuclear device.
The practical effect of the current policy creates an armed FBI team to resolve the tactical situation, followed closely by an unarmed military EOD technician to perform the render safe procedures, who is in turn supported by DOE scientists back at the labs.
In a terrorist incident, a crisis management response may include traditional law enforcement missions, such as intelligence, surveillance, tactical operations, negotiations, forensics, and investigations, as well as technical support missions, such as agent identification, search, render safe procedures
, transfer and disposal, and limited decontamination.
