During Fiscal Year 2008, ten events that occurred at facilities licensed or otherwise regulated by the NRC and/or Agreement States were determined to be AOs. Section 208 of the Energy Reorganization Act of 1974 (Pub. L. 93-438) defines an abnormal occurrence (AO) as an unscheduled incident or event which the U.S. Nuclear Regulatory Commission (NRC) determines to be significant from the standpoint of public health or safety. The Federal Reports Elimination and Sunset Act of 1995 (Pub. L. 104-68) requires that AOs be reported to Congress annually.
The report describes five events at NRC-licensed facilities. The first NRC-licensee event involved radiation exposure to an embryo/fetus. The other four NRC-licensee events were medical events, as defined in Title 10, Part 35, of the Code of Federal Regulations (10 CFR Part 35). All five NRC-licensee events occurred at medical institutions. The report also describes five events at Agreement State-licensed facilities. The first Agreement State-licensee event involved radiation exposure to an embryo/fetus. The other four Agreement State-licensee events were medical events, as defined in 10 CFR Part 35, and occurred at medical institutions. As required by Section 208, the discussion for each event includes the date and place, nature and probable consequences, the cause or causes, and the actions taken to prevent recurrence. Each event is also being described in NUREG-0090, Vol. 31, "Report to Congress on Abnormal Occurrences: Fiscal Year 2008.'' This report is available electronically at the NRC Web site.
