Nuclear regulators do not fine Calvert Cliffs for security violation

Federal regulators have declined to impose a civil penalty against Calvert Cliffs nuclear power plant in Southern Maryland after determining that an unspecified security violation had taken place at the facility.

The Nuclear Regulatory Commission said in a letter Thursday that plant owner Constellation Energy Nuclear Group had "promptly" reported the problem to the agency and that the company had addressed the issue quickly.

"Therefore, to encourage identification of violations, and prompt and comprehensive correction of violations, I have been authorized, after consultation with the Director, Office of Enforcement, not to propose a civil penalty in this case," William M. Dean, the NRC's regional administrator, said in the letter, noting that significant future violations could result in civil penalties.

The federal agency has not disclosed the nature of the problems that occurred last year, saying that doing so might enable an attack or sabotage at the twin-reactor plant in Lusby in Calvert County.

Officials of Constellation Energy Nuclear Group could not immediately be reached Thursday.
