Integrated Source Management Portfolio (ISMP)

The Integrated Source Management Portfolio (ISMP) is a set of information technology tools that supports the Radioactive Material Security Program and related radioactive materials licensing and tracking activities of the U.S. Nuclear Regulatory Commission (NRC). The key systems that comprise the ISMP include the National Source Tracking System (NSTS), the Web-Based Licensing (WBL) System and the future License Verification System (LVS). When integrated, these systems will form a comprehensive program to ensure the security and control of radioactive material by tracking information on all NRC and Agreement State licensees and more than 75,000 high-risk radioactive sources possessed by approximately 1,300 licensees.

For more details on the ISMP, please visit the ISMP Website.

To begin the credentialing process, please visit Get credentialed for ISMP systems.

If you have any questions or concerns, please contact the NRC's  Integrated Source Management Portfolio Help Desk at 877-671-6787.
