SOURCESīackgrounder on the Three Mile Island Accident. Dismantling the remaining reactor could take up to 10 years. The Unit 1 reactor is owned and operated by Exelon Corporation.Įxelon announced in 2017 that it would close the plant in 2019. Three Mile Island Nuclear Generating Station today generates power from its Unit 1 reactor. High profile protests in response to the events at Three Mile Island took place around the country, including one in New York City in 1979 involving 200,000 people. The anti-nuclear movement emerged as a social movement against the global nuclear arms race in the early 1960s at the height of the Cold War. The Three Mile Island incident helped to galvanize the anti-nuclear movement in the United States. Radioactive fuel and water were removed, and workers eventually shipped 15 tons of radioactive waste to a nuclear waste storage facility in Idaho. The damaged reactor was permanently closed and entombed in concrete after the accident. MacMillan said, adding that the one in use at Three Mile Island had not been designed by Babcock &Wilcox but by the overall plant contractor, the engineering firm of Burns & Roe.The cleanup effort lasted 14 years and cost an estimated 1 billion dollars. Thus, buttons could be pushed, and valves inadverently opened and closed, by leaning an elbow on a certain spot on the control Panel.Ī lot of work has gone into new designs for control moms,” Mr. Panel lights indicating whether specific valves are open or shut, for example, are color coded in a way that is just the reverse of a traffic light: On the control panel, red means open, and green means closed.įurther, the buttons one pushes to open and close such valves are not covered, as they are on other control panels. Subsequent to the Three Mile Island accident, major changes were made internationally to reduce the potential for. Download to: EndNote BibTeX use BibTeX for Zotero.

THREE MILE ISLAND NUCLEAR ACCIDENT SIMULATION SIMULATOR
In the two months since the Three mile Island accident, for example, 175 operators from various utilities have received training in a control room simulator in a Babcock & Wilcox plant here. to prevent accidents The use of simulators for severe accident training by Luis Lederman Simulation training at the Three Mile Island nuclear plant in Pennsylvania. The issue is of more than academic interest, since Babcock & Wilcox trains the operators of the nuclear equipment that sells. Sandia began its studies of responses to severe nuclear accidents shortly after the Three Mile Island incident in 1979 that radically altered the future of nuclear power in the United States. “On hindsight, we should have trained operators in multiple failures,” Mr. DOE and the Nuclear Regulatory Commission sponsored the report and have planned follow-up severe accident analyses. However, they did acknowledge that at least one piece of equipment for which they were responsible, a valve, had not worked properly, and that Metropolitan Edison personnel trained as plant operators by Babcock & Wilcox had not been taught to deal with the sort of complicated problem that arose at Three Mile Island.
