An energy company is staging the final test of its emergency warning sirens at a closed nuclear plant in southern New Jersey.

Exelon Generation says it will test the sirens at the Oyster Creek Generating Station in Lacey Township around noon on Tuesday.

The 42 sirens within a 10-mile radius of the plant in Ocean County are a signal to tune to local Emergency Alert Broadcast TV or radio station and not to evacuate.

Oyster Creek ceased operations in September. But the siren system remains active in accordance with local, state, and federal emergency planning requirements.

The facility is located 60 miles east of Philadelphia. It produced enough electricity each year to supply about 600,000 typical homes.
