RUTLAND, Vt. (AP) - The Shumlin administration has asked the Nuclear Regulatory Commission for information about malfunctioning radiation monitors at the Vermont Yankee nuclear plant. The plant's owner said radiation monitors produced false signals but did not fail.
Darren Springer, deputy commissioner of the Department of Public Safety, sent a letter to the NRC questioning the 60-day period allowed for Entergy to file a report. Springer said "failure of the radiation monitoring equipment is a serious issue."
Entergy spokesman Robert Williams told the Rutland Herald that the radiation monitors performed their proper function in controlling ventilation of the reactor building. Nonetheless, he said Entergy decided as a precaution to replace the four monitors.
The false signals showed high radiation levels in the primary containment isolation system. Workers confirmed that radiation levels were normal.
