The Smithsonian National Museum of American History doesn't shy away from the recent historical past, and this recent online exhibit details the events surrounding March 28, 1979. This auspicious date happened to be the day of the worst reported accident at a civilian nuclear power plant, in which half the fuel melted in one of two nuclear reactors on Three Mile Island near Harrisburg, Pennsylvania. To recognize the 25th anniversary of this event, the National Museum of American History created a substantial display-case style exhibit, and also created this nice online exhibit. The online exhibit contains 12 separate sections and includes various photographs and other visual materials that appeared in the Museum of American history in the spring of 2004. Visitors can also get some sense of the chronology of nuclear power in the United States by taking a look at section 11, which features a brief timeline of relevant events. The site is rounded out by a bibliography of other readings which may be of interest.
