After fixing a vibration problem, Beaver Valley nuclear power station near Shippingport in Pennsylvania resumed 100 percent power Monday afternoon, ending a nearly two-week shutdown for one of its two units.

Unit No. 2 came back online just after 5 p.m. Sunday, said FirstEnergy Corp. spokeswoman Jennifer Young. The unit had been down since May 28 when sensors picked up small, but unusual vibrations in the power generator.

The company ramped up its production until it hit 100 percent around 2 p.m. Monday, Young said.

Workers fixed the vibration problem — which turned out to be slackened wires — and replaced two seals on coolant pumps connected to the nuclear reactor, according to the company and the Nuclear Regulatory Commission.

Company workers used the downtime to replace them because they had been working inefficiently, Young said.
