DOE-STD-3028-2000

Oxide

Stable uranium-oxygen (U-O) compounds in the UO2-UO3

composition range (generally UO2, U3O8, and UO3). Uranium

oxides are often a mixture of U-O compounds.

Package

The assembled combination of sealed containers required by

this Standard (an inner and an outer), together with the

contained stable 233U oxides or metals and any additional

interior convenience container(s) into which they initially have

been placed.

Repackaging

A process whereby an existing storage container is opened

and stabilized material transferred to a Package that meets

the requirements of this Standard.

Specific Surface Area

The surface area per unit mass of solid.

A process to eliminate the tendency of a 233U species to react

Stabilization

with atmospheric components or reactive associated

constituents. This generally means conversion to oxide and

elimination of associated material that could undergo

radiolysis during storage thus creating an overpressurization

in the sealed package.

Waste

For the purposes of this Standard, waste has all of the

following:

1. no existing or planned use,

2. no potential for weapons use (<12% 233U in 238U, or

equivalent), and

3. no unacceptable criticality safety risk (e.g., <0.67% or

equivalent).
