LACEY TOWNSHIP - The Oyster Creek nuclear power plant will test its emergency sirens on Tuesday.
The test is part of a twice-yearly safety drill.
The plant's parent company, Exelon Generation, recently replaced all 42 emergency warning sirens in the 10-mile radius around the Lacey Township plant with new units featuring battery backup.
The test will take place around 10 a.m.
The work is part of an $11 million project to replace 400 sirens at the four nuclear power plants Exelon owns in the mid-Atlantic region.
The purpose of the sirens is to notify residents to tune to a radio or television station in case of an emergency.
