A control problem with a turbine at a nuclear power plant in South Carolina has shut the reactor down until the issue can be fixed. It's the third shutdown this year.
Raleigh, N.C.-based Progress Energy reported Thursday's incident at the H.B. Robinson plant in Hartsville to the Nuclear Regulatory Commission.
Plant spokesman Andy Cole says the shutdown was triggered by a control problem with a turbine unrelated to the nuclear side of the plant. The reactor shuts down as a safety precaution during certain conditions at the plant.
Earlier this year, two fires in Robinson's electrical system led to a nearly four-month shutdown of the plant that included a planned refueling outage and some needed repairs. The reactor was restarted in mid-July.
