Calvert Cliffs reactor shuts down

A spokesman for the Calvert Cliffs nuclear power plant says one of its two reactors has shut down automatically after the unit's link to the regional power grid apparently failed.

Spokesman David Fitz said the reactor at the Southern Maryland nuclear plant shut down shortly before 2 p.m. Wednesday. He said the incident was under investigation, and it was not known how long it would take to bring the unit back online.

Fitz says the reactor normally provides about 10 percent of the state's electricity.
