http://hisz.rsoe.hu/alertmap/index.php?smp=&lang=engA blown fuse triggered a low-level emergency event at Duke Energy's Oconee Nuclear Station today. According to Duke spokesperson Addie Bradshaw, at 12:07pm workers were doing planned maintenance on an instrument panel when a fuse went out. The blown fuse took out several indicators in the control room for reactor 3. The indicators, according to Bradshaw, are visual and audible alarms that assist employees in monitoring operations at the plant but do not directly affect operations themselves. "To use an analogy, it's like the 'low fuel' light in your car. Even if it fails to come on, you still have the needle on the fuel gauge to tell you it's low," says Bradshaw. She says repairs are still in progress to fix the fuse and test all alarm systems affected by the outage. The incident prompted Duke to issue what is called a "notice of unusual event" to the Nuclear Regulatory Commission. This is the lowest of four categories of emergency classification. Bradshaw says she does not know if the NRC will take any action in response to this notice, but she says the agency was fully aware the moment it happened because NRC inspectors work on site at the plant. She emphasizes this incident never directly impacted operations and at no time did the plant lose power.
