1 of 2 reactors at Md. nuclear plant shuts down

Reactor at Calvert Cliffs nuclear plant in Md. shut down after malfunction during testing

LUSBY, Md. (AP) -- Constellation Energy Nuclear Group says it has shut down one of two nuclear reactors at its Calvert Cliffs power plant after a malfunction during testing.

Plant spokesman Kory Raftery says a control rod dropped into the reactor Thursday during tests at the Southern Maryland plant and it was shut down. He said Friday that electrical maintenance will be performed, but it's not clear when unit 2 will return to service.

Nuclear Regulatory Commission spokesman Neil Sheehan says the plant must shut down within six hours if a rod can't be withdrawn. He says inspectors will follow the maintenance.

Raftery says there's no public safety threat, and an investigation found no link to a shutdown in May.

The plant is located along the Chesapeake Bay, about 70 miles south of Baltimore.
