The first Monday of the month means it’s regular testing time for Exelon’s Limerick Generating Station. The company will test the nuclear plant’s new siren system today around 2 p.m.
People within 10 miles may be able to hear the steady three-minute tone when the system is activated, and again during the test. The whole thing should wrap up around 2:30.
As Pottstown Patch reports, the company is testing its new battery back-up system, which will be fully implemented later this year. The sirens can be used to alert nearby residents of an emergency, but today, they’re just for show (and sound).
