Dear Licensee,

The U.S. Nuclear Regulatory Commission (NRC) is issuing the Regulatory Issue Summary (RIS) to inform licensees possessing Category 1 and 2 radioactive sources of the process to complete the National Source Tracking System (NSTS) Annual Inventory Reconciliation and to inform licensees that the primary communication tool for NSTS updates will be the NSTS Blog (www.nrc.gov/security/byproduct/nsts/blog.html) and the NSTS website (www.nrc.gov/security/byproduct/nsts.html).

January 2010 marks the first Annual Inventory Reconciliation. Licensees can complete this process either through the online NSTS or manually via fax, mail, or email. Part of the reconciliation process will include resolving any discrepancies between the information in the NSTS and the actual inventory. The reconciliation is to occur during the month of January, and by January 31, 2010, each licensee must submit confirmation to the NSTS that the data in the system is correct.

Since January 2010 is the first time the Annual Inventory Reconciliation will be completed, the NRC staff developed a User's Guide which provides step-by-step instructions for completing the Annual Inventory Reconciliation. This User's Guide is available on the website at www.nrc.gov/security/byproduct/nsts.html. A paper copy of the User's Guide is available by request through the NSTS Help Desk (1-877-671-6787).

The Illinois Emergency Management Agency, Division of Nuclear Safety (the Agency), is responsible for compliance with this requirement under 32 Ill. Adm. Code 330.950 and will be monitoring the timely reconciliation of inventories in Illinois. If you have any questions, please contact the Agency, the NRC at the above websites or the NSTS Help Desk at (1-877-671-6787).
