What is the Annual Inventory Reconciliation?

The NRC and Agreement State regulations require licensees to reconcile their physical source inventories with the source inventory in the NSTS annually each January. Licensees can complete this process through the online application or by email/fax/mail. The NRC is encouraging all licensees to complete their annual inventory reconciliation through the online application.

What if I will not be able to get online access in time to do my Annual Inventory Reconciliation in January?

Licensees without online access will contact the NSTS Help Desk for a copy of their Annual Inventory Reconciliation package. The Help Desk will send the licensee the package which includes a copy of your inventory, an AIR confirmation form, and an AIR correction form, by secure email. This package will contain all of the necessary information to complete the AIR.

How do I confirm my inventory or make corrections?

Licensees can confirm their inventory online using the Annual Inventory Reconciliation link on the NSTS main menu. Licensees without online access will use the inventory report from NSTS to verify it reflects what is in their physical source inventory. If there is a discrepancy in the report, licensees must make the correction and submit it to the Help Desk along with any supporting documentation (i.e., NRC Form 748s if adding or removing a source from the inventory; a source certificate if changing the source serial number, model number, or manufacturer; a copy of the license or license amendment if changing the RSO or address). A correction cover sheet is in the AIR package for your convenience. Once the Help Desk has made the correction, they will notify you it is complete. A new inventory package will be emailed. Once the licensee has confirmed the sources in the NSTS inventory are the sources in the physical inventory, they must complete and submit the confirmation form to the NSTS Help Desk. Once the Help Desk receives the confirmation of Annual Inventory Reconciliation, they will enter the reconciliation information on behalf of the licensee.

What if sources in an inventory correction do not match what was on the initial report, due to source transfers and receipts that occur during the month of January?

This may occur, since any newly generated inventory report will be up-to-date with current transactions. As long as the information is correct as of the date on the inventory report, licensees should complete the reconciliation.
