Understanding Inventory Difference – ID [Energy]: A Legal Perspective

Definition & Meaning

The term Inventory Difference (ID) refers to the difference between the recorded amount of special nuclear material (SNM) in a company's books and the actual amount found during a physical inventory check. This difference is calculated by taking the book inventory quantity, which includes the beginning inventory plus any additions and minus any removals, and subtracting the physical inventory quantity determined at the end of the inventory period. In formula terms, it can be expressed as:

ID = (BI + A - R) - EI

Where:

  • BI: Beginning Inventory
  • A: Additions to Inventory
  • R: Removals from Inventory
  • EI: Ending Inventory

Real-world examples

Here are a couple of examples of abatement:

Example 1: A nuclear facility conducts a physical inventory and finds that it has 50 kilograms of SNM. The book inventory shows 60 kilograms after accounting for additions and removals. The Inventory Difference is calculated as:

ID = (60) - (50) = 10 kilograms.

Hypothetical Example: If a facility reports an addition of 20 kilograms to its inventory but fails to account for a removal of 5 kilograms, the book inventory may inaccurately reflect a higher quantity than what is physically present.
