America’s first new nuclear reactor in 20 years finished one of its final rounds of testing late Wednesday.
The Tennessee Valley Authority’s (TVA) rector test reached 75 percent of its total output and could begin operations later this month. Once testing is complete, Watts Bar Unit 2 will be the nation’s first new commercially operating nuclear unit since 1996.
TVA’s reactor will begin producing and selling 1,150 megawatts of electricity to the Tennessee Valley, powering roughly 1.3 million homes when combined with the plant’s other reactor.
TVA, a federal government-owned utility, started construction on Watts Bar Unit 2 reactor 44 years ago, but construction was put on hold in 1985 — after more than $1 billion had been spent — due to a scandal involving contractors paying off corrupt TVA officials. The reactor was 80 percent complete before the scandal halted construction. TVA revived the project in 2007, when nuclear power seemed poised to make a comeback.
The new reactor was initially projected to cost $2.2 billion, but costs increased to $4.7 billion because of overruns and new compliance standards implemented in the aftermath of the 2011 Fukushima disaster in Japan.
America currently operates 99 nuclear reactors across 61 commercially operated nuclear power plants, according to the U.S. Energy Information Administration. The average nuclear plant employs between 400 and 700 highly-skilled workers, has a payroll of about $40 million and contributes $470 million to the local economy, according to the Nuclear Energy Institute. The Watts Bar plant will support an estimated 1,000 full-time jobs.
