#### Nuclear Materials – National Source Tracking System

The National Source Tracking System, also known as NSTS, tracks more than 76,000 sources held by about 1,400 NRC and Agreement State licensees. Of those sources, about 52 percent are Category 1 sources and 48 percent are Category 2. The majority are cobalt-60, the most widely used isotope in large sources.

#### Nuclear Materials – Domestic Safeguards

The NRC and the U.S. Department of Energy (DOE) use the Nuclear Materials Management and Safeguards System (NMMSS) to track transfers and inventories of source and special nuclear material. Licensees must report their inventories, transfers, purchases, and sales (including import and export) of these materials to the NMMSS. More than 300 licensees report to the NMMSS database, verifying their inventories at least annually by reconciling their transactions against the previous year’s inventory. The database supports U.S. participation in the Treaty on the Non-Proliferation of Nuclear Weapons.

#### Radioactive Waste – Low-Level Radioactive Waste

                      - More than 3 million packages of radioactive materials are shipped each year in the United States by road, rail, air, or water. This represents less than 1 percent of the Nation’s yearly hazardous material shipments.

#### High-Level Radioactive Waste Management – Decommissioning

                      - Approximately 100 materials licenses are terminated each year. The NRC’s decommissioning program focuses on the termination of licenses that are not routine and that require complex activities.
                      - 25 nuclear power reactors are in various stages of decommissioning (DECON or SAFSTOR), including Duane Arnold (one reactor), which shutdown on August 10, 2020.

                      - Five NRC-licensed uranium recovery facilities are in various stages of decommissioning.

#### Security and Emergency Preparedness

                      - Every 2 years, each operating nuclear power plant performs a full-scale emergency preparedness exercise inspected by the NRC and evaluated by the Federal Emergency Management Agency (FEMA).
                      - Plants conduct additional emergency drills between full-scale exercises to maintain their preparedness and proficiency in responding to emergencies.
                      - The NRC spends about 15,000 hours a year scrutinizing security at nuclear power plants, including 8,000 hours of force-on-force inspections. These inspections include mock combat drills and are conducted on a cycle so that each plant undergoes a force-on-force inspection every 3 years.
                      - The NRC has implemented a comprehensive cybersecurity oversight program for power reactors, which includes routine inspections and requires licensees to isolate critical systems from the Internet.
