ATLANTA (AP) — A nuclear power plant in New Jersey is no longer under an alert caused by superstorm Sandy.

The U.S. Nuclear Regulatory Commission said an alert at the Oyster Creek plant in Forked River, N.J., ended early Wednesday. An alert is the second-lowest designation in a four-tiered warning system.

The alert was triggered as water rose outside the plant, threatening cooling equipment. NRC officials said water levels had since fallen and were still dropping. The plant, which was offline before the storm, also regained offsite power after losing it.

Storm-related complications were blamed for forcing reactors off line at Nine Mile Point Unit 1 near Syracuse, N.Y., the Indian Point Unit 3 north of New York City and the Salem plant’s Unit 1 on the Delaware River in New Jersey.
