At first the high radiation readings seemed like it could be a big problem, but afterward Vermont Yankee nuclear plant officials said they were false alarms.
Yankee reported to the Nuclear Regulatory Commission (NRC) last Wednesday that a radiation detector on the plant’s refueling floor issued notifications that it was getting high readings twice, once in June, once in July.
Plant spokesman Robert Williams says the plant’s ventilation system began shutting down, as it’s designed to do when there is a recording of high radiation readings. But he said follow-up checks showed the high readings were false.
Williams said officials addressed the problem with the replacement of four radiation detectors in the plant.
