Item facility

A facility where all nuclear material is kept in item form and the integrity of the item remains unaltered during its residence at the facility. In such cases, IAEA safeguards are based on item accountancy procedures (e.g., item counting and identification, non-destructive measurements of nuclear material and the verification of the continued integrity of the items). Examples of item facilities are most reactors and critical assemblies (critical facilities), and storage installations for reactor fuel.
