The siren that went off Friday afternoon at the Shearon Harris Nuclear Power Plant resulted from an accidental activation, authorities said.

A spokesman for Duke Energy, which owns the plant in New Hill, N.C. in southern Wake County, said the energy company is investigating what prompted the alarm to sound shortly before 1 p.m. The siren prompted a flurry of calls to WRAL News and posts on social media.
