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 License Verification System (LVS). The integration of these systems 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 80,000 high-risk radioactive sources possessed by approximately 1,300 licensees.
