The Nuclear Regulatory Commission cannot issue a license for the construction and operation of a new nuclear reactor in Maryland–that is the ruling of the NRC’s Atomic Safety and Licensing Board (ASLB) handed down Thursday.

Michael Mariotte, Executive director of NIRS, called Thursday’s decision “a blow to the so-called ‘nuclear renaissance,’” noting that back in 2007, when permit requests were submitted for Calvert Cliffs 3, the project was considered the “flagship” of a coming fleet of new reactors. “Now,” said Mariotte, “it is a symbol or the deservedly failed revival of nuclear power in the US.”

A symbol, yes, but far from the only symbol.
