The Nuclear Regulatory Commission and the U.S. Army Corps of Engineers, Baltimore District, said no environmental impacts preclude issuing the combined license for the proposed 1,500 MW Unit 3 at the Calvert Cliffs nuclear power plant in Maryland.
UniStar applied for a license to build and operate an Areva EPR reactor next to the existing reactor at Calvert Cliffs. The planned EPR is a pressurized-water reactor with an output of 1,500 MW.
The NRC’s Atomic Safety and Licensing Board is currently conducting a proceeding on a challenge to the staff’s environmental review. The NRC is also considering whether UniStar meets NRC requirements regarding foreign ownership. These items must be resolved before the NRC can reach a final decision on the combined license application.
The NRC said April 8 that UniStar was ineligible to build the third reactor because it is owned by Electricite de France SA (EDF). Federal law prohibits complete ownership or control of a U.S. nuclear plant by a foreign entity.
In October 2010, Constellation Energy pulled out of negotiations with EDF for a $7.5 billion federal loan guarantee to build the reactor. EDF bought out Constellation’s share in UniStar for $249 million in November. EDF has said it is working to find another partner for the project. On April 28, Constellation and Exelon announced plans to merge.
