Exelon to test Limerick plant’s new siren system

    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).
