UNIRRADIATED ENRICHED URANIUM STORAGE FACILITIES.
Introduction . UEUSFs are used to store unirradiated enriched uranium in a
solid, liquid, or gaseous form. UEUSF activities may include shipping, receiving,
handling, packaging, and unpackaging.
Design Considerations . The design should accomplish the following:
Accommodate planned UEU handling and storage activities (e.g.,
analysis, shipping and receiving operations, packaging, and
unpackaging). The build-up of packaged materials or packaging
materials should be minimized. Receiving operations involving removal of
radioactive material from protective shipping containers should be
performed in the unpackaging room(s).
Incorporate into the design ALARA concepts to minimize overall effects
on workers, the public, and the environment.
Provide sufficient versatility to accommodate equipment for programmatic
changes, programmatic modifications, and multishift operations.
Provide sufficient spacing between compartments to facilitate relocation
and maintenance of equipment and ease of manual or automatic storage
Facilitate expeditious identification, inventory, placement, and retrieval of
Provide for sufficient spacing and arrangement of compartments and/or
containers to facilitate the taking of inventories. Vault doors, racks, and
containers should be designed to accommodate the application of
tamper-indicating devices. Adequate space for measurement capability
should be provided for the required inventory verification and/or
