Phạm vi áp dụng / Scope of standard

This standard establishes guidelines concerning control of and
accounting for special nuclear material (SNM) at nuclear power
plants.

The guidelines set forth in this standard are applicable to SNM
and various material mixtures containing SNM. Generally, the SNM
involved is plutonium, ²³³U, or uranium enriched in the
isotope ²³⁵U. The ²³⁵U content will vary
depending on the type of reactor and various reactor parameters.
SNM is typically in the form of pellets encapsulated in fuel
rods.

Guidelines are set forth for the fundamentals of a SNM control
and accounting system, including criteria for the receipt, internal
control, physical inventory, and shipment of SNM.
