(Middletown) - A test of Three Mile Island nuclear power plant in Dauphin County did not go as expected.

Its new emergency notification siren system failed to sound during a scheduled test this afternoon.

The original siren system sounded during the first of two tests at 12:15 p.m., but Exelon spokesman Ralph DeSantis says none of the 96 new sirens sounded during a second test at 1:15 p.m.

DeSantis says the plant is looking for the cause.

The new system includes a battery backup capability that is supposed to allow 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.
