moisture content. The correlation of the weight percent criterion with bounding

pressures in storage containers is established in Appendix B (Derivation of Pressure

Equation) and earlier sections of this Appendix.

A.6.1.3

Engineered Materials

1. For purposes of this Standard, fabricated fuel made from metals or sintered oxide

fuels are considered to be stabilized and contained provided that the cladding has

retained its integrity. When there is assurance of cladding integrity, the stabilization

requirements of this Standard are deemed to have been satisfied.

2. Sintered oxide fuel pellets qualified for nuclear fuel are quite pure, have controlled

stoichiometry, and have been formed at more elevated temperatures than specified

in this Standard for stabilization. Consequently, unirradiated pellets need only meet

the moisture criterion in Criterion 6.1.2.3 to be considered "stabilized material" and

to be eligible for packaging. Pellet materials that do not meet that criterion should be

stabilized according to the provisions of Criterion 6.1.2.1 of this Standard.

A.6.1.4

Storage after Stabilization Deferred Packaging

The stabilization step, together with verification of stabilization at that time, provides

certainty that the material was stable at a point in time. A high degree of confidence

that the material is still stable is provided by the observation that the container and

material appear unchanged and the moisture content remains acceptably low.

Evidence of change would include, for example, corrosion or substantial pitting of the

container, or significant discoloration of the contents. To provide assurance of

stability, verification of the moisture content is required, either by measurement, or

by some other defensible analysis.

Containers - the "Packaging"

A.6.2.1

Container Design Concept

1. The design goals for the storage package are that it be maintenance free and

compatible with existing or planned qualified shipping containers without further

reprocessing or repackaging.

A sealed container design, rather than a container design with a gas filter, was
