Our Mission*To license and regulate the nation's civilian use of byproduct, source, and special nuclearmaterialsto 5 nuclear materials to ensure adequate protection of public health and safety, promote the common defense and security, and protect the

environment Some Nuclear Facts*104 nuclear power plants supply about 20 percent of the electricity in the U.S.*Nuclear materials are used inmedicinefordiagnosis 6 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 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 7*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 What We Don't Do*Regulate nuclear weapons, military reactors, or space vehicle reactors 8*Own or operate nuclear power plants*Regulate some radioactive materials, such as X-rays and naturally

occurring radon How We Regulate*Establish rules and regulations*Issue licenses

Safety Significant Findings or PIs*The NRC identified one finding of moderate safety significance and twenty findings of low safety significance in 2011.

21*The White finding was due to a design issue which impacted the way the Unit 1 safety related battery chargers operated during specific plant events.*The Unit 1 performance indicators remained green throughout 2011 Prairie Island Unit 1January 1 -December 31, 2011*Unit 1 operated in the Licensee Response Column for the 1 stquarter of the assessment period 22*Unit 1 operated in the Regulatory Response Column for the remaining 3 quarters of 2011, based upon the White finding for the battery chargers*A supplemental inspection for the White finding was completed in February 2012.
