OAK HARBOR, Ohio (AP) — A northwest Ohio nuclear power plant is getting a $600 million upgrade.
FirstEnergy Corp. has begun work to replace the two original steam generators at the Davis-Besse nuclear plant near Toledo.
The (Toledo) Blade (http://cin.ci/1fYsr9R ) reports that the scheduled maintenance took about a decade of planning and is expected to infuse $108 million in the local economy.
Steam generator replacement projects are typically the most expensive maintenance done at nuclear plants that have pressurized-water reactors.
The generators being installed at Davis-Besse are 74 feet long by 12 feet wide, and weigh 470 tons. They act as heat exchangers and produce super-hot steam used to spin the plant's turbine generator to produce electricity.
