WBAL TV, Baltimore’s NBC affiliate, just posted a report on the Unusual Event at Calvert Cliffs:
Calvert Cliffs, a Southern Maryland nuclear power plant, automatically went offline overnight.
Constellation Energy Nuclear Group spokesman Mark Sullivan released a statement shortly before 2 a.m. saying the Calvert Cliffs facility is safe and stable. He said an “Unusual Event” has been declared, which is the lowest of four emergency classifications by the National Regulatory Commission.
The facility’s Unit 2 is stable and operating at 100 percent power.
Sullivan said heavy wind gusts associated with Hurricane Irene blew a large piece of aluminum siding from a building, which then struck the facility’s man transformer.
The Unusual Event status will be lifted upon completion of the state’s emergency response plan.
Sullivan said all employees were safe, the facility is safe and there is no impact to employees or the facility’s neighbors. There is no threat.
