I hope the backup diesel generators at all nuclear plants in the affected area have started up. Loss of offsite power is a major design basis accident for nuclear plants.

Never heard of that.

Looks like all nuke plants started their diesels where needed. From NRC web site:

The Nuclear Regulatory Commission has been informed that the following nuclear power plants shut down today due to grid instabilities:

Indian Point 2 and 3 (in New York)
Perry (in Ohio)
Fermi (in Michigan)
Ginna (in New York)
FitzPatrick (in New York)
Oyster Creek (in N.J.)
Nine Mile Point 1 and 2 (in New York)

All plants are in a safe condition, using their emergency diesel generators where appropriate. NRC resident inspectors will continue to monitor the situation at the affected plants.

The NRC is monitoring the situation from its Regional and Headquarters Operations Center. Acting Chairman Merrifield is in contact with other federal agencies, including the Department of Homeland Security.
