Baltimore, August 29, 2011 — The Calvert Cliffs facility, operated by Constellation Energy Nuclear Group (CENG) continues to be safe, secure and stable after Hurricane Irene came through the area over the weekend.
Unit 1 remains in safe shutdown after a piece of aluminum siding was dislodged from a nearby building by wind gusts and struck a transformer causing the Unit to go safely off-line. Unit 1 shut down automatically and safely as it is designed to do. Operators in the control room followed procedures and managed the event as trained.
Inspections of the transformer are underway. We are working through our procedures and Outage protocols and making sure equipment is in good order to determine when Unit 1 will be safely brought back on-line. We will not bring the Unit back on-line until all required precautionary testing has been completed. Safety is our number one priority and value.
Calvert Cliffs’ Unit 2 remains at 100 percent power.
Two representatives from the Nuclear Regulatory Commission (NRC) are on-site at Calvert.
We will continue partnering with local, state and federal officials; we have strong partnerships in our communities.
CENG employees have done a remarkable job preparing the site for the storm, and working around-the-clock to keep the Calvert Cliffs facility safe, secure and stable.
Our thoughts are also with all our neighbors in Calvert and St. Mary’s Counties as they work to rebound from the storm.
When we bring Calvert’s Unit 1 back on-line, we will distribute internal communications and a press statement.
