SOME NUCLEAR FACTS 94 nuclear power plants supply about 20 percent of the electricity in the U.S.

Nuclear materials are used in medicine for diagnosis and cancer treatment Nuclear materials are widely used in industry, such as in density gauges, flow measurement devices, radiography devices, and irradiators 5

THE NRC REGULATES Nuclear reactors - commercial power reactors, research and test reactors, new reactor designs Nuclear materials - nuclear reactor fuel, radioactive materials for medical, industrial, and academic use Nuclear waste - transportation, storage and disposal of nuclear material and waste, decommissioning of nuclear facilities Nuclear security - physical security of nuclear facilities and materials from sabotage or attacks 6

HOW WE REGULATE Establish rules and regulations Issue licenses Provide oversight through inspection, enforcement, and evaluation of operational experience Conduct research to provide support for regulatory decisions Respond to events and emergencies 7

WHAT WE DONT DO Regulate nuclear weapons, military reactors, or space vehicle reactors Own or operate nuclear power plants Regulate some radioactive materials, such as X-rays and naturally occurring radon 8
