Peach Bottom Atomic Power Station, a nuclear power plant, is located 50 miles (80 km) southeast of Harrisburg in Peach Bottom Township, York County, Pennsylvania, on the Susquehanna River three miles north of the Maryland border.
The Philadelphia Electric Company (later shortened first to PECO Energy and later to just PECO) became one of the pioneers in the commercial nuclear industry when it ordered Peach Bottom 1 in 1958. The U.S.'s first nuclear power plant (the Shippingport Reactor) had gone on line a year earlier. Peach Bottom Unit 1 was an experimental helium-cooled, graphite-moderated reactor. It operated from 1966 to 1974. The other two units, General Electric boiling water reactors, placed on-line in 1974, are still in operation on the 620-acre (2.5 km2) site. Both Units 2 and 3, originally rated at 3,514 megawatts thermal (MWth), equivalent to about 1,180 megawatts of electricity (MWe) each, were uprated to 3,951 megawatts thermal (MWth), equivalent to about 1,308 megawatts net of electricity (MWe) each in 2014. Their licenses run until 2033 (Unit 2) and 2034 (Unit 3).
Peach Bottom is operated by the Exelon and is jointly owned by Exelon (50%) and Public Service Enterprise Group (PSEG) Power LLC (50%).
Peach Bottom was one of the plants analyzed in the NUREG-1150 safety analysis study.
The Nuclear Regulatory Commission defines two emergency planning zones around nuclear power plants: a plume exposure pathway zone with a radius of 10 miles (16 km), concerned primarily with exposure to, and inhalation of, airborne radioactive contamination, and an ingestion pathway zone of about 50 miles (80 km), concerned primarily with ingestion of food and liquid contaminated by radioactivity.
