UNIRRADIATED ENRICHED URANIUM STORAGE FACILITIES.

2.3.1

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.

2.3.2

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

operations.

Facilitate expeditious identification, inventory, placement, and retrieval of

storage containers.

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
