Missouri's sole nuclear power plant is back online after being shut down for more than three weeks.
Ameren Missouri's Callaway Energy Center was taken off line July 26 after an electrical arc caused a small fire. The plant resumed operations Sunday morning. Spokesman Cleve Reasoner says the arc was triggered when a ventilation louver came loose and got too close to the power cables.
"Testing confirmed that there was no impact to the major components," Reasoner said. "So the repairs were those that were associated directly with correction of the arc damage."
Missouri's lone nuclear reactor remains shut down while workers and officials continue to investigate what caused a small fire at the Callaway County plant Friday night.
Ameren Missouri spokesman Cleve Reasoner said it'll be several days before the plant is back online.
"We are assessing impacts from the arc that we had in our cable leading from the plant," Reasoner said. "We've begun disassembling equipment and investigating what the nature of the damage is and what the nature of the cause(s) of the event are."
