TOLEDO, Ohio - A nuclear reactor in Ohio is running again, less than two months after cracks were discovered in the plant's concrete shell.
FirstEnergy Corp. says its Davis-Besse nuclear plant outside Toledo began producing electricity Tuesday morning and should be at full power later this week.
The Nuclear Regulatory Commission on Friday gave the utility the green light to restart the plant after saying FirstEnergy provided reasonable assurance that the cracks don't pose a threat. Regulators say they've also done their own checks and reviewed test results.
An Ohio congressman criticized the decision, saying that it's still not known what caused the cracks or whether it's a bigger problem.
The cracks were discovered while the plant was closed to replace its reactor head.
