TVA's Watts Bar Unit 2 Achieves Commercial Operation
LCG, October 21 2016--The Tennessee Valley Authority (TVA) announced Wednesday that its Watts Bar Unit 2 nuclear facility has achieved commercial operation. The 1,150-MW electric generating facility, located approximately 50 miles northeast of Chattanooga, Tennessee, is the first new nuclear reactor in the U.S. in twenty years.
TVA's president and CEO stated, "TVA's mission is to make life better in the Valley by providing reliable, low-cost energy, protecting our area's natural resources and working to attract business and growth - all priorities simultaneously supported by the completion of Watts Bar Unit 2."
The original construction on Watts Bar 2 started over 40 years ago in 1972. However, when load growth forecasts dropped in 1988, the unit was deferred. When Watts Bar 1 began commercial operations in May 1996, it became the last commercial nuclear unit in the U.S. to come on-line. Construction on Unit 2 resumed in 2007. The capacity of Unit 1 and Unit 2 are 1,100 MW and 1,150 MW, respectively, and both units are pressurized-water reactors. TVA stated that the $4.7 billion capital construction project was completed on budget.
The Nuclear Regulatory Commission (NRC) issued the 40-year Operating License to TVA for the Watts Bar Unit 2 nuclear reactor last October.
TVA's executive vice president of generation and chief nuclear officer stated, "Nuclear power remains the only source of carbon-free energy that is available 24 hours a day, seven days a week. TVA believes that Watts Bar Unit 2, and other nuclear units like it across the Valley and the nation, represents a vital investment in our clean energy future."
The Nuclear Energy Institute's president and chief executive officer stated, "This is a histori day. At a time when our nation and the world are seeking cleaner sources of affordable, reliable energy, Watts Bar Unit 2 is poised to produce tremendous environmental and economic benefits for communities in the Tennessee Valley for decades to come. On behalf of the nuclear energy industry, the Nuclear Energy Institute congratulates TVA and its supporting contractors and suppliers for this outstanding accomplishment."
