A 1971 federal decision banned river-water cooling for new plants, so a cooling tower was added to the design. Location authorization was issued on 31 October 1972 and construction began in 1973. The single pressurized water reactor was supplied by Kraftwerk Union (Siemens). It was connected to the grid on 2 February 1979, and commercial operation began on 1 November 1979 after a safety review that followed the Three Mile Island accident. Large protests took place between 1977 and 1981.
