Calvert Cliffs Nuclear Plant Security Faulted

Federal nuclear safety inspectors found unspecified "security deficiencies" at the Calvert Cliffs nuclear power plant in southern Maryland earlier this year, the Nuclear Regulatory Commission disclosed Wednesday.

NRC spokesman Neil Sheehan said the agency could not reveal the nature of the problem or discuss why it had conducted a special inspection of the plant from Jan. 26 through July 13. The five-member commission has refused since the 2001 terrorist attacks to release information about security, out of concern it might help people or groups seeking to attack or sabotage a nuclear plant, the agency spokesman said.

But the finding was deemed of "at least low to moderate significance" and further NRC scrutiny may be warranted, Sheehan said in an email. Constellation Energy Nuclear Group operates the twin-reactor plant on the Chesapeake Bay in Lusby, about 70 miles south of Baltimore.
