• A low-pressure coolant injection flow control valve failed at the Browns Ferry Nuclear Plant, Unit 1 in Alabama on Oct. 23, 2010, and the NRC said that affected potential fire control.
• The NRC listed 23 events involving medical radioactive materials that met the criterion of involving "a major reduction in the degree of protection of public health and safety."
• Three other utility-related events mentioned because of high public interest were the Japanese event at Fukushima Dai-ichi nuclear plant, flooding at Fort Calhoun plant in Nebraska, and the August 2011 earthquake near the North Anna plant in Virginia.

Two of the 23 events involved exposure of an embryo or fetus, one event involved an exposure to the extremities of a radiographer, and a fourth involved a stolen gamma radiography camera. The remaining 19 events involved misadministration of radioactive material during diagnostic or therapeutic procedures.
