From the article:

• A handful of Mid-Atlantic nuclear reactors are expected to shut down ahead of Hurricane Sandy's anticipated Monday-night landfall.
• Public Service Enterprise Group Inc's New Jersey-based Salem and Hope Creek plants could get hit before the storm moves off of the ocean, and electricity traders predicted that shutdowns may occur Monday.
• Other plants in Maryland and New Jersey may be affected as well, though, the storm may lose enough strength that shutdowns will not be necessary.

Dive Summary:

"... Electricity traders said if Sandy continues on her expected path it was likely PSEG would have to shut the Salem and Hope Creek reactors later Monday, but they were mixed on whether the storm's winds would still be strong enough to force the shutdown of the Pennsylvania and Maryland reactors.

All U.S. reactors have procedures that require operators to shut the units before hurricane-force winds reach their sites or when floodwaters reach certain levels. ..."
