More than four decades after construction began, the Watts Bar-2 reactor was finally connected to the grid on 3 June 2016. However, two days later, while operating at 12.5 percent power, the reactor automatically shut down.

As of 8 June 2016, the reactor has not restarted and no restart schedule has been fixed yet, according to a spokesperson for plant owner the Tennessee Valley Authority (TVA).
