A nuclear power plant in New Jersey is on "alert" after waters from Sandy reached high levels. The plant was already offline for maintenance when the storm hit.
The Nuclear Regulatory Commission says an ``unusual event'' was declared around 7 p.m. when water reached a high level. The situation was upgraded less than two hours later to an "alert," the second-lowest in a four-tiered warning system.
Federal officials say all nuclear plants are still in safe condition. They say water levels near Oyster Creek, which is along the Atlantic Ocean, will likely recede within a few hours.
