Tests on the concrete have not given inspectors any reason to keep the plant shut down, said Cynthia Pederson, a regional director with the U.S. Nuclear Regulatory Commission, who oversees plants in the Midwest.
"We have a very vigorous inspection we did, and it's still ongoing," Ms. Pederson
told concerned citizens at a public meeting near the Davis-Besse
nuclear plant, just outside Toledo.
Until the cause is known, there's no reason to order closer inspections at other plants with similar concrete shields, Ms. Pederson
It's possible that the cracks have been around for a while, she
said, adding, "Concrete has a tendency to crack."
Rep. Dennis Kucinich, D-Ohio, a longtime foe of the plant and its owner, on Thursday criticized the NRC decision to let the plant reopen.
also said FirstEnergy
downplayed the cracks' scope and waited too long to tell the public about where they were found.
