(Corrects comment from NRC in last paragraph of story published June 7 on whether the leak must be reported.)
FirstEnergy Corp. (FE:US) is repairing a leak discovered June 6 as it restarted Davis-Besse nuclear station in Ohio following a refueling outage, a company spokeswoman said.
FirstEnergy can’t say for competitive reasons when it expects to complete the repair to the reactor’s coolant system or when the 913-megawatt unit will come online, Jennifer Young, a spokeswoman for the Akron, Ohio-based company said in a telephone phone interview today.
The amount of radioactive water that sprayed through the pinhole-sized leak was “relatively small” and no radiation was discharged from the plant, Young said.
Because the leak was from a pressure boundary in a system that contains the reactor and radioactive coolant, the company was required to report the incident to the U.S. Nuclear Regulatory Commission.
“When the leak was identified as coming from a pressure boundary, the plant was required to report it to the NRC, shut the plant down and fix it,” Viktoria Mitlyng, a spokeswoman for the agency in Lisle, Illinois, said in an e-mailed statement.
