HARTSVILLE, S.C. – A change in the settings reportedly caused the sirens surrounding the H.B. Robinson nuclear plant to sound on Feb. 9.
A Duke Energy spokesman said on March 2 that a setting was changed as new software for the siren system was being installed. That caused an automatic test of the sirens at around 8 a.m. on Feb. 9.
The software has since been checked and additional controls have been added to manage changes to the software system in the future.
There are sirens surrounding the plant to alert residents living nearby of emergencies at the facility located along Lake Robinson.
When residents move into Hartsville, they’re given a large pamphlet by the power company of what to do should an emergency occur. This pamphlet is then provided to residents each year.
