MIDDLETOWN, Pa. (AP) — The Three Mile Island nuclear plant in central Pennsylvania will be conducting separate tests of its emergency systems.
Officials at the plant will conduct a test of the original siren system at 12:15 p.m. Thursday. Then, the plant will test the new, upgraded siren system an hour later, at 1:15 p.m.
For both tests, all 96 sirens within 10 miles of the facility will sound for three minutes. The new system includes a battery backup capability that allows the sirens to sound even if there’s a power outage.
The partial meltdown of a Three Mile Island reactor in 1979 is considered the worst commercial nuclear power plant accident in U.S. history.
