In a periodic ritual familiar to residents who live near a nuclear power plant, Progress Energy will sound the emergency warning sirens for the Shearon Harris plant at full blast tomorrow morning.
The Raleigh-based power company will conduct a full-volume test for about 5 seconds between 10 a.m. and 11 a.m. The Shearon Harris nuclear plant has 83 warning sirens within 10 miles of the power plant.
The nuclear siren, which resembles an air-raid warning, is not likely to be mistaken for the afternoon bell at the local schoolhouse.
Progress is required to have a notification system in place in the event of an accident that results in a radioactive release. In past years, the sirens have failed the test, but since then the utility has replaced them at a cost of $2.5 million.
