The Nuclear Regulatory Commission said that UniStar has retracted its application for a third reactor at the Calvert Cliffs Nuclear Power Plant in Lusby, Md.
The NRC said Tuesday that it had approved of the retraction as of last Friday, SoMDNews reported.
With the withdrawn application, UniStar goes back to square one with any application for a third reactor at the facility 40 miles south of Annapolis, which is operated by Exelon Generation Company's Constellation Energy.
French nuclear plant engineering firm Areva had been contracted in 2007 to work the design through the application process, but had suspended work in March, the report said.
