NSTS Reconciliation Time

It's almost time for the NSTS Annual Inventory Reconciliation (AIR) again! Please take some time to make sure that you have submitted any missing transactions so that your NSTS inventories are accurate. The NSTS is a critical component of the National Materials Program and enhances the ability of NRC and Agreement States to conduct inspections and investigations, communicate information to other government agencies, and verify legitimate ownership and use of nationally tracked sources.

In the coming weeks, licensees with above threshold sources by the end of December will be receiving hard copy packages in the mail in early January. Those of you with online access don't have to wait until you receive your package; you will be able to complete your AIR online starting January 1st.  If you have any questions about the AIR process, please contact the NSTS Help Desk at 1-877-671-6787 or email

Happy holidays!

NSTS Fax Number Reminder

Back in 2012, the fax number for the NSTS Help Desk was updated to 1-888-821-2534. It has come to our attention that several licensees are still submitting transactions to NSTS via our old fax number. In the coming weeks, we will be disconnecting the old fax number. Please update your contact lists and fax machines with the updated fax number (1-888-821-2534) so that your transactions continue to be processed in a timely manner.
