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 are rated at 3,514 megawatts thermal (MWth), equivalent to about 1,180 megawatts of electricity (MWe) each. Their licenses run until 2033 (Unit 2) and 2034 (Unit 3).
Peach Bottom is operated by the Exelon Corporation 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.

[edit] Surrounding population
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.[1]
The 2010 U.S. population within 10 miles (16 km) of Peach Bottom was 46,536, an increase of 7.2 percent in a decade, according to an analysis of U.S. Census data for msnbc.com. The 2010 U.S. population within 50 miles (80 km) was 5,526,343, an increase of 10.6 percent since 2000. Cities within 50 miles include Baltimore (36 miles to city center).[2]
[edit] Safety concerns
On March 31, 1987 US Peach Bottom units 2 and 3 shutdown due to cooling malfunctions and unexplained equipment problems.
In September 2007, former employee Kerry Beal videotaped Peach Bottom security guards sleeping on the job. Beal had previously tried to notify supervisors at Wackenhut Corp. and the US Nuclear Regulatory Commission.[3] He was eventually fired during the Exelon security transition, a decision which made a list of the 101 "dumbest moments in business" in the Jan 16, 2008 issue of Fortune.[4]
[edit] Seismic risk
The Nuclear Regulatory Commission's estimate of the risk each year of an earthquake intense enough to cause core damage to the reactor at Peach Bottom was 1 in 41,667, according to an NRC study published in August 2010.[5][6]
