Westinghouse, a unit of Japanese conglomerate Toshiba Corp (>> Toshiba Corp), is building two reactors for Georgia Power and partners at the Vogtle site in Georgia and two for South Carolina Electric & Gas (SCE&G) and its partner in South Carolina.

The utilities, units of Southern Co (>> Southern Co) (Georgia Power) and Scana Corp (>> SCANA Corporation) (SCE&G), have not cancelled the reactor projects but said they were evaluating options.

All 99 of the reactors now in service in the United States were started before the Three Mile Island accident in Pennsylvania in 1979.

At that time, utilities had construction permits from the U.S. Nuclear Regulatory Commission (NRC) to build around 97 reactors, most of which were already under construction. The utilities only put in service 53 of those reactors.

See below for a list of reactors that were never finished after obtaining a construction permit from the NRC, according to data from the NRC and Reuters:
