provide sufficient spacing between compartments to facilitate relocation
and maintenance of equipment in case of manual or automatic storage
facilitate expeditious identification, inventory, placement, and retrieval of
Facility layout should provide for efficient cleaning, maintenance, and ease of
inspection and should consider the requirements for secure location of storage
containers, traffic control, and segregation. Door locations should be
coordinated with aisles to facilitate access to stored material, for loading and
unloading of material, for use of fire fighting equipment, and for compliance with
National Fire Code (NFC) NFPA 101, Code for Safety to Life from Fire in
Buildings and Structures. Bumpers should be provided where necessary to
minimize potential damage to the structure of racks from handling equipment.
New storage facilities should be physically separated from process operations,
storage of nonnuclear materials, flammable or explosive materials or equipment,
and functions not directly required for storage operations.
Combustible packaging materials should be stored in metal containers or
structures outside a PSF in a location that will not endanger the storage facility or
stored material if a fire occurs in the packaging material. No hazardous gases or
liquids should be used in PSFs. No natural gas or other fossil fuels should be
used for heating purposes unless the heating occurs in a separate building that
is clearly isolated from the primary facility.
The design should provide for sufficient spacing and arrangement of
compartments and/or containers to facilitate the taking of inventories. Vault
doors, racks, and containers should accommodate the application of tamper-
indicating devices. Adequate space for measurement should be provided for the
required inventory verification and/or confirmation. An automated vault
surveillance system should be provided where excessive radiation exposure
would result from entry for material control and accountability purposes. The
design of the vault and/or system should facilitate inventory requirements.
