Pipe leak shuts reactor at Calvert Cliffs

Maryland Watch

July 25, 1998

Baltimore Gas and Electric Co. abruptly shut down one of two reactors at its Calvert Cliffs Nuclear Power Plant in Lusby late Thursday, after workers discovered a leak in a steam pipe.

The manual shutdown of the Unit 2 reactor marks the first time since November 1996 that the reactor has stopped operating. The automatic shutdown that occurred then stemmed from a low water level in the reactor's steam generator.

BGE spokesman Karl R. Neddenien said repairs to the pipe, which is in a non-nuclear area of the plant, would take "several days."

He said there were no injuries in the incident, which occurred at 6: 20 p.m. Thursday. Calvert Cliffs' Unit 1 reactor continues to operate at full power.

On an annual basis, the nuclear plant's two 850 megawatt reactors supply more than 40 percent of the company's electricity to its 1.1 million customers.

The shutdown came as BGE is attempting to become the nation's first nuclear plant owner to extend its operating license. The U.S. Nuclear Regulatory Commission is expected to decide on the utility's application in 2003. Calvert Cliffs' license expires in 2014.
