Siren testing planned at Limerick nuclear plant June 1 & June 2
Constellation will conduct its semi-annual, full-volume test of the emergency warning sirens surrounding Limerick nuclear generating station on Monday, June 1, at approximately 2 p.m., and again on Tuesday, June 2, at various intervals throughout the day.
This is one of two semi-annual tests performed each year.
The warning siren system consists of sirens located within a 10-mile radius around Limerick.
The sirens are not a signal to evacuate, but a warning to tune to a local Emergency Alert Broadcast television or radio station. County emergency management authorities activate the sirens.
