Susquehanna Steam Electric Station

OPERATOR: Talen Energy

http://www.susquehannanuclear.com/

LOCATION: 7 miles NE of Berwick Pennsylvania

ADDRESS: Susquehanna Nuclear, LLC 769 Salem Blvd. Berwick, PA 18603

OPERATING LICENSE UNIT 1: Issued – July 17,1982, Expires – July 17, 2042

OPERATING LICENSE UNIT 2: Issued – March 23, 1984, Expires – March 23, 2044

REACTOR TYPE: Boiling Water Reactor (BWR)

ELECTRICAL OUTPUT UNIT 1: 1315 Megawatts Electrical (MWe)

ELECTRICAL OUTPUT UNIT 2: 1315 Megawatts Electrical (MWe)

Located on a hilltop overlooking the scenic Susquehanna River Valley in northeastern Pennsylvania, the Susquehanna Steam Electric Station (SSES) is a 2,630-megawatt facility with two boiling water reactors and two closed-cycle cooling towers. As a result of Extended Power Uprate (EPU) work, Susquehanna now proudly operates one of the largest Boiling Water Reactor (BWR) sites in the United States, generating more than 2,600 megawatts in total, at optimum conditions.

Susquehanna is located about seven miles north of Berwick and is owned jointly by Susquehanna Nuclear LLC and Allegheny Electric Cooperative Inc. and is operated by Susquehanna Nuclear LLC, one of Talen Energy Corporation’s generating affiliates. For information, visit www.susquehannanuclear.com.

Pennsylvania Power & Light applied to the U.S. Nuclear Regulatory Commission for a construction permit in April 1971. The NRC issued the permit Nov. 2, 1973, and construction began later that month. Unit 1 began commercial operations in 1983 and Unit 2 in 1985. The units began generating electricity under 40-year operating licenses. In November 2009, following a rigorous process and review, the NRC granted a 20-year extension of the original licenses, allowing both Susquehanna units to operate until 2042 and 2044, respectively.

The 1,200-acre site located in Salem Township, Luzerne County, was selected for its stable geology, available cooling water from the Susquehanna River, accessible power supply lines to other parts of the service area and convenient highway and rail transportation. General Electric Co. designed the plant’s twin reactors. Bechtel Power Corp. served as the primary contractor.

With equipment and system upgrades completed during the 2010 and 2011 refueling and maintenance outage, respectively, Unit 1 and Unit 2 became the largest BWRs in terms of thermal power and generating capacity in the United States. When operating at 100 percent power, each unit has the capacity of 3,952 megawatts thermal (a measure of the heat produced in the reactor) and over 1,300 megawatts electrical (a measure of the electricity produced by the generator).

Xcel Energy’s nuclear power plants help us avoid producing hundreds of millions of tons of greenhouse gases during their operating lives. Our nuclear resources have been the backbone of our clean energy system for decades. Nuclear is also central to meeting our ambitious proposal for a clean energy future for the Upper Midwest: a 60% carbon reduction, and 63% carbon-free generation mix by 2030.

Fermi 2 Power Plant

OPERATOR: DTE Energy

http://dteenergy.com/nuclear/

LOCATION: 30 miles south Detroit Michigan

ADDRESS: Fermi Nuclear Station 6400 N. Dixie Hwy Newport, MI 48166

OPERATING LICENSE UNIT 1: Issued - July 15, 1985, Expires - March 20, 2045

REACTOR TYPE: Boiling Water Reactor (BWR)

ELECTRICAL OUTPUT UNIT 1: 1122 Megawatts Electrical (MWe)

At 1.1 million kilowatts, Fermi 2 represents 30 percent of Michigan’s total nuclear generating capacity. This single-unit plant can produce enough electricity to serve a city of about one million people. Fuel costs are about half those of the most efficient coal-fired plants.

Fermi 2 began commercial operation in 1988. The plant employs about 850 workers and produces about 15 percent of the power generated by DTE’s power plants.

In December, 2016, Fermi 2 received renewal of its operating license from the U.S. Nuclear Regulatory Commission. The renewal enables Fermi 2 to produce electricity for its customers in southeast Michigan until 2045.

In 2001, Fermi 2 was the first nuclear power plant in the state to achieve Clean Corporate Citizen (C3) status. The Department of Environmental Quality’s voluntary C3 program recognizes top performers in environmental management and stewardship. Fermi 2 has maintained the designation every year since 2001. The plant has also maintained Wildlife Habitat Council certification since 2000 and has set aside 600 acres for inclusion in the Detroit River International Wildlife Refuge. That property is managed by the U.S. Fish and Wildlife Service.

Fermi 2 is owned by Detroit-based DTE Energy. It is located along the western shores of Lake Erie in Monroe County, Mich.

The Cook Nuclear Plant is located on 650 acres along Lake Michigan’s eastern shoreline. The tract is part of the world’s largest formation of freshwater dunes. The plant is owned and operated by American Electric Power.

The construction permit for the plant was granted by the Atomic Energy Commission in 1969. It was one of the largest construction projects ever in the state of Michigan with over 2,000 workers at the site. The plant was named for the late Donald C. Cook, a Michigan native, and former chairman of the board of American Electric Power. Unit 1 began commercial operation in August of 1975 and Unit 2 in July of 1978.

Both units are pressurized water reactors. The 1,030 net megawatt (MW) Unit 1 and 1,077 net MW Unit 2 combined produce enough electricity for more than one and one half million average homes. The American Electric Power Service Corporation served as architect and engineer for the project. The nuclear steam supply system for both units were designed and built by Westinghouse Corporation. The turbine generators for Unit 1 and Unit 2 were purchased from General Electric Company and Brown Boveri Corporation respectively.

AEP’s nuclear generation group is headquartered in Buchanan, Michigan. The building, located twenty miles from the plant, also houses some of the nuclear plant’s emergency plan facilities.

American Electric Power is one of the largest electric utilities in the United States, delivering electricity to more than 5 million customers in 11 states. AEP ranks among the nation’s largest generators of electricity, owning nearly 38,000 megawatts of generating capacity in the U.S. AEP also owns the nation’s largest electricity transmission system, a nearly 39,000-mile network that includes more 765 kilovolt extra-high voltage transmission lines than all other U.S. transmission systems combined. AEP’s transmission system directly or indirectly serves about 10 percent of the electricity demand in the Eastern Interconnection, the interconnected transmission system that covers 38 eastern and central U.S. states and eastern Canada, and approximately 11 percent of the electricity demand in ERCOT, the transmission system that covers much of Texas. AEP’s utility units operate as AEP Ohio, AEP Texas, Appalachian Power (in Virginia and West Virginia), AEP Appalachian Power (in Tennessee), Indiana Michigan Power, Kentucky Power, Public Service Company of Oklahoma, and Southwestern Electric Power Company (in Arkansas, Louisiana and east Texas). AEP’s headquarters are in Columbus, Ohio.
