Calvert Cliffs Unit 1 Offline


Lusby, MD: Calvert Cliffs Unit 1 shut down automatically today at 4:26 p.m. due to an electrical component failure on the non-nuclear side of the plant. All systems responded as designed and Unit 2 remains at full power.

The electrical component detects moisture in steam. Moisture in the steam can affect the operation of the unit's turbine. Technicians will determine the cause of the malfunction and replace and fully test the module before returning the unit to service.​

Calvert Cliffs is located on the western shore of the Chesapeake Bay in Calvert County and is Maryland's only nuclear energy facility.  The station is home to two pressurized water reactors capable of generating 1,756 megawatts combined. Units 1 and 2 began commercial operation in 1975 and 1977, respectively. Join us on Twitter and You Tube.
