Vogtle 3&4 - Cleaner Energy Means Clean Air

  1. 1. Cleaner energymeans Cleaner air. Plant Vogtle Units 3 and 4
  2. 2. Zero greenhoUse gases.nuclear energy plants release zero greenhouse gases whileproducing electricity. a single uranium pellet the size of a pencileraser produces as much electricity as 17,000 cubic feet of naturalgas, 1,780 pounds of coal or 149 gallons of oil. nuclear powerplants already provide about 20 percent of the power generatedin georgia. nuclear energy is clean, safe and proven. Throughenergy efficiency, conservation, new renewable energy sources,nuclear energy, and new environmental controls, we can continueto make our energy supply cleaner and more secure.

Turbine generatorpressure turbinevessel N uclear power plants generate electricity using the same control pumprods engineering technology as conventional steam plants that burn reactorcore generator fossil fuels like coal, oil or natural gas. The difference is the pump heat source used to make steam. Fuel rods in the reactor core containment structure contain uranium pellets. The uranium atoms undergo a chain Typical Pressurized Water Reactor (PWR) Design reaction where they split, or fission, creating heat. When water is pumped around the hot fuel rods, it absorbs this heat. In a pressurized reactor, like those at Plant Vogtle, this water is kept under high pressure, like a pressure cooker. This superheated water is sent through tubes in a steam generator where cooler water surrounds it and boils to steam. The two water sources remain separated from each other; only the heat is transferred. The steam turns blades on a turbine generator, causing it to spin a magnet inside a coil of wire. The motion causes electrons to move along the wire in a constant flow called an electric current. Water from the cooling tower condenses the remaining steam and it flows back to the cooling tower where excess heat is given off as a mist above the tower. The new units 3 and 4 at Plant Vogtle will use Westinghouse Advanced Passive (AP1000) technology. These units operate using the same basic technology as a traditional nuclear plant; however, the new units incorporate advancements and improvements in nuclear technology. These units build on proven nuclear technology, while also incorporating improvements in that technology. These new units will include passive safety systems that use natural forces like gravity and compressed air instead of active machinery like pumps or fans. The new units will be built using modular construction techniques. Many of the parts will be assembled away from the plant. These parts will be put together in large modules that will be transported to the plant site and assembled together there. This technique allows more construction activities to be per- formed in parallel, reducing construction time and cost. – 2 –

  6. 6. will iT be bUilT ?New units are under construction at Plant Vogtle. Construction began in April 2009 and will continue through 2017. In August 2009, Southern Nuclear received an Early Site Permit (ESP) for the units. The ESP is one step in the Nuclear Regulatory Commission’s (NRC) licensing process for new units. Completion of the ESP process resolves many site safety and environmental issues and determines the site is suitable to build a nuclear energy plant. Southern Nuclear’s ESP was issued with a Limited Work Authorization that allows limited safety construction to begin prior to receiving a license to construct and operate the plant. Based on the NRC’s schedule, the company anticipates receiving a Combined Construction and Operating License (COL) in 2011. The COL provides one license to both construct and operate the plant. Issuance of the COL clears the way for all construction activities at the plant. Plant Vogtle Units 3 and 4 are the U.S. nuclear industry’s reference plant for Westinghouse AP1000 technology. As the reference plant, these units will be the first ones in America to be licensed to oper-ate using AP1000 technology. Plant Vogtle Units 3 and 4 will be among the first new nuclear plants constructed in America in more than 30 years.The Georgia Public Service Commission approved the project in March 2009. Southern Nuclear plans for Unit 3 to be operational in 2016 and Unit 4 in 2017. – 4 –
  7. 7. are The owners ?Georgia Power is the largest subsidiary of Southern Company, one of the nation’s largest generators of electricity. The company is an investor-owned, tax-paying utility with rates well below the national aver-age. Georgia Power serves 2.3 million customers in all but four of Georgia’s 159 counties. Oglethorpe Power Corporation is a $4.9 billion power supply cooperative serving 38 Electric Membership Corporations (EMCs) in Georgia. These EMCs provide retail electric service to more than 4.1 million Georgians throughout the state. Oglethorpe Power is the nation’s largest electric cooperative in terms of assets, annual kilowatt-hour sales and ultimate consumers served. The Municipal Electric Authority of Georgia (MEAG Power), headquartered in Atlanta, is a public genera-tion and transmission corporation providing power to 49 Georgia communities with annual electric sales in excess of $721 million and more than 10 million megawatt hours of delivered energy in 2006. MEAG Power has assets of more than $4.9 billion, co-owns four generating plants with a generating capacity of 1,566 megawatts and has sole ownership of a combined cycle facility with a generating capacity of 503 megawatts. Dalton Utilities has operated as a public utility since 1889 and provides potable water, electrical, natural gas and wastewater treatment services to approximately 73,000 customers in the City of Dalton and portions of Whitfield, Murray, Gordon, Catoosa and Floyd counties. In 2003, Dalton Utilities launched OptiLink and now provides broadband, cable tv, telephone and internet services to residential and busi-ness customers.Southern Nuclear, a subsidiary of Southern Company, operates the Edwin I. Hatch Nuclear Plant near Baxley, Ga., the Joseph M. Farley Nuclear Plant near Dothan, Ala. and the Alvin W. Vogtle Electric Generating Plant near Waynesboro, Ga. – 5 –
