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.
