A generator problem has halted the restart of a nuclear reactor at Dominion Virginia Power's North Anna power plant.
Dominion took Unit 2 out of service in late March for refueling and routine maintenance. The utility began restarted the reactor over the weekend.
The U.S. Nuclear Regulatory Commission says the reactor was operating at 74 percent capacity Tuesday when a generator lockout occurred during automatic voltage regulator testing.
The commission says the reactor was stable Wednesday morning. Dominion and the commission are investigating the generator problem.
North Anna's other reactor is operating at 100 percent capacity.
