Stabilized Materials

DOE-STD-3013-2004

pass the LOI test even though their moisture content may be acceptably low. Research

supporting this Standard has also shown that the stabilization process removes or destroys

all materials that pose a threat to the integrity of the container except for readsorbed

moisture on the oxide material. This Standard allows moisture-specific measurements to be

used as an alternate to the LOI test to verify stability.

Research and analysis have shown that physical changes that occur in plutonium metal at

temperatures that may be achieved within the heat generation limit in this standard during

transportation or in storage do not pose a threat to the integrity of the container. The

resulting removal of the metal temperature limit allows shipment in conveyances that do not

refrigerate their payloads and permits a markedly less expensive design for vault HVAC

intake structures.

The reduction in the wattage limit from 30 w to 19 w reduces anticipated storage

temperatures, bringing them more in line with practical storage and experimental

experience.

Corrosion issues, particularly those involving chlorides, have been addressed and

recommendations on container materials provided.
