May 2007 Calvert Cliffs Nuclear Power Plant Earns a Place in History Located about an hour south of Washington, D.C., Constellation Energys Calvert Cliffs Nuclear Power Plant is an important part of Constellation Energys generation fleet. The Constellation Energy team operates two nuclear reactors at Calvert Cliffs, generating about 1,700 megawatts of electricity each day - enough power for a third of Marylands homes and businesses. In many ways, Calvert Cliffs has earned a place in nuclear energy history.
In the early 1970s, Calvert Cliffs became the first nuclear power In 2005, Calvert Cliffs surpassed its own outage record completing plant team in the U.S. to work through an Environmental Impact Unit 2 refueling in 21 days - one of the shortest outages ever Statement under the 1969 National Environmental Policy Act achieved for a Combustion Engineering-designed nuclear reactor.

The environmental studies conducted concluded that During Calvert Cliffs 2006 and 2007 refueling outages, the plant Calvert Cliffs would produce electricity safely and efficiently in replaced and inspected systems and equipment as a proactive concert with the delicate environment of the Chesapeake Bay.

Equipment enhancements approved by the federal government, Calvert Cliffs began included reactor vessel head (RVH) replacements, a new turbine operations. The U.S. Nuclear Regulatory Commission licensed control system, containment sump modification, upgrades to main reactor Unit 1 through 2014 and Unit 2 through 2016. condenser and circulating water systems, as well as, reactor coolant system inspection and maintenance.
In 2000, Constellation Energys Calvert Cliffs made history again by becoming the first nuclear power plant in the nation to earn extended licenses from the U.S. Nuclear Regulatory Commission. The extended licenses represented a commitment to produce safe, reliable and efficient electricity at Calvert Cliffs through 2034 and 2036.
In 2003, Constellation Energy reached a world record by safely completing the Calvert Cliffs Unit 2 outage in 66 days. The outage included refueling, replacing the Units two steam generators lower assemblies, refurbishing the steam generator upper assemblies, and replacing the Units two main step-up transformers.
During 2004, Constellation Energy achieved another U.S. energy industry record for duration in replacing three low-pressure Constellation Energys Calvert Cliffs Nuclear Power Plant turbines on Calvert Cliffs' Unit 1. The outage team completed this produces enough electricity to power a fifth of Marylands homes and businesses.
