      March 5, Cleveland Plain Dealer – ( Ohio ) Walkie talkie disrupts safety system at Davis-Besse nuclear plant. The Davis-Besse nuclear power plant in Oak Harbor , Ohio went “radio-inactive” March 3 — losing its emergency water cooling system for 2 minutes — due to a technician’s walkie talkie. The technician used his walkie talkie in a room containing a back-up or auxiliary control panel for a system designed to automatically pump water into the reactor in the event of a catastrophic accident. The radio wave disrupted the signal from the control panel to special pumps and emergency valves that even on stand-by are electrically alive for an instantaneous reaction. In two bursts of conversation lasting 8 seconds and 19 seconds during a 2-minute period, the technician rendered the plant’s entire emergency shutdown system inoperable, the company told federal regulators March 3. The company posted a sign on the door to the room warning all employees not to key radios near the sensitive control panel, a company spokesman said. The incident should have never happened, said a nuclear safety engineer with the Union of Concerned Scientists. He said such incidents occurred many times in the early 1980s, so much that the Nuclear Regulatory Commission (NRC) issued a warning bulletin in December 1983. “This hasn’t happened in decades,” he said. “We will definitely be looking into this,” said a spokeswoman for the NRC’s regional office in Chicago .
