TVA’s Watts Bar 2 hits 33% power generation

The Tennessee Valley Authority (TVA) Watts Bar 2 nuclear unit was listed at 33% power generation early June 20, by the Nuclear Regulatory Commission (NRC) and that’s about the highest output the reactor has reached since TVA started powering it up a few weeks ago.

NRC has, on more than one day, listed Watts Bar 2 at 28% generation.

Watts Bar Unit 2 was officially synced to the grid on June 3 and TVA operators continue to gradually increase power generation at the roughly 1,150-MW facility in Spring City, Tennessee. Eventually, as testing continues, TVA will increase power generation to 100%.

When it connected to the grid, Watts Bar 2 became the first nuclear power plant to come online since 1996, when Watts Bar Unit 1 started operations, according to the Energy Information Administration (EIA).

Watts Bar Unit 2 is the first nuclear plant in the United States to meet new regulations from the NRC that were established after the 2011 earthquake and tsunami that damaged the Fukushima Daiichi Nuclear Plant in Japan, EIA noted.
