Officials keep close eye on nuclear power plants as Sandy's winds whip

Though no nuclear power plants have been taken offline so far, officials along the east coast are overseeing plants carefully as hurricane Sandy makes landfall in New Jersey.

Federal regulators and safety officials at nuclear power plants along the Eastern Seaboard were keeping a watchful eye on wind and water levels, preparing to shut plants down should super-storm Sandy send levels surging.

Still, by Monday evening, before the storm made landfall along the coast of New Jersey, no plants had been taken offline.

The US agency that oversees nuclear safety, its own headquarters and Northeast regional office shuttered by Sandy, dispatched extra inspectors or placed them on standby in five states, equipped with satellite phones to ensure uninterrupted contact.

Nuclear power plants are built to withstand hurricanes, airplane collisions and other major disasters, but safety procedures call for plants to be shut down when hurricane-force winds are present at the site, or if water levels nearby exceed certain flood limits.

At the Salem and Hope Creek plants in Hancocks Bridge, N.J., which together produce enough power for about 3 million homes per day, officials were watching for sustained winds of 74 mph or greater that would trigger taking the plants offline. The nearby Delaware River posed another hazard if water levels exceed 99.5 feet, compared with a normal level of 89 feet.

Joe Delmar, a spokesman for Public Service Enterprise Group Inc., said that only essential employees had been asked to report to work but that current projections were that the plants would not have to close.

One of the units at Salem had already been offline due to regular refueling and maintenance. That was also the case at Oyster Creek, a 636-megawatt plant in Lacey Township, N.J., roughly 60 miles east of Philadelphia.

In Lusby, Md., the Calvert Cliffs Nuclear Power Plant was operating at full power — enough to power more than 1 million homes. Additional staff, both onsite and off, were called in to prepare for the storm. Safety officials there will take the plant offline if sustained winds exceed 75 mph or water levels rise more than 10 feet above normal sea level.

Seventy-five was also the number at Indian Point in Buchanan, N.Y., where officials said they were fully prepared to withstand surging water levels from the Hudson River. At Pennsylvania's Susquehanna plant in Salem Township, officials were ready to activate their emergency plan, a precursor to taking the plant offline, if sustained winds hit 80 mph.
