Peach Bottom 2&3
Location: PA
Operator: Exelon Nuclear
Configuration: 2 X 1,182 MW BWR
Operation: 1974
Reactor supplier: GE
T/G supplier: GE
EPC: Bechtel
Quick facts: Peach Bottom has a 600ac site on the west bank of Conowingo Pond. The plant is co-owned by Exelon Generation and PSEG on a 50:50 basis. These units began commercial operation in Jul and Dec 1974, respectively. 2009 output was 18.6 TWh.Peach Bottom-1 was a 40-MW helium-cooled reactor in operation from 1967-1974.

Location: PA
Operator: Saxton Nuclear Experimental Corp, General Public Utilities
Configuration: 1 X 10 MW PWR
Operation: 1962 (ret 1972)
Reactor supplier: WH
T/G supplier: ??
Quick facts: Construction of the $8.5mn facility began in the late 1950s and it was the fifth U.S. nuclear plant in operation, used for training hundreds of operators and engineers worldwide. Steam was supplied to an existing 10-MW set formerly used by a coal-fired boiler.  Decommissioning began in 1998 and was completed in 2005 when the 150ac site was returned to its natural state to be turned over to the property owner Pennsylvania Electric Co. In 2003, the American Nuclear Society designated Saxton as an historic landmark.

Location: PA
Operator: PPL Susquehanna
Configuration: 2 X 1,176 MW BWR
Operation: 1983-1985
Reactor supplier: GE
T/G supplier: GE
EPC: Bechtel
Quick facts: In 2009, Susquehanna set a new station generation record with 19,492 GWh output, besting the previous record of 19,046 GWh set the previous year. In Apr 2009, Unit-2 ended a company-record 723 days of continuous operation. This is the second-best U.S. plant run ever. During 2008, the Unit-1 HP turbine was replaced as part of a refueling and maintenance outage. PPL and UniStar plan to build an Areva EPR near the Susquehanna site. This will be known as the Bell Bend station.

Location: PA
Operator: Atomic Energy Commission, Duquesne Light Co
Configuration: 1 X 100 MW PWR
Operation: 1957  (ret 1982)
Reactor supplier: WH, AEC
T/G supplier: WH
EPC: WH, Stone & Webster
Quick facts: This is considered the first commercial nuclear power station in the United States. Ground was broken in 1954 by President Dwight D Eisenhower, who also opened the plant on 26 May 1958, as part of his "Atoms for Peace" program. First power was on 18 Dec 1957 after 32mos of construction and the expenditure of $72.5mn. The original reactor plant was capable of about 60 MWe of output and was designed by the Westinghouse Electric Corp in cooperation with the Division of Naval Reactors of the Atomic Energy Commission and was based on a light water reactor design for a proposed aircraft carrier. Shippingport was used to test different designs and materials for fuels and reactor components and the reactor was rebuilt in the late 1970s and ended up with about 100 MWe of capacity. The facility was named an ASME Landmark in May 1980 and the site was later used to build Beaver Valley (2 X 888 MW). The original plant was dismantled starting in Sep 1985.
