Some three hours after dawn Wednesday, Oct. 11, there will be a quarterly reminder of this local power source throughout the areas of New Hanover and Brunswick counties bordering the mouth of the Cape Fear River.

The 38 outdoor warning sirens located within 10 miles of the Brunswick Nuclear Plant will be tested at full volume for ten seconds between 10 a.m. and 11 a.m. Wednesday. The test may be performed more than once to make sure each siren works properly.

In New Hanover county, that 10 miles includes all of Kure Beach and Carolina Beach, and the southern tip of Federal Point with a siren at the old Coast Guard LORAN station on River Road.

This test is performed every three months, in coordination with emergency officials in Brunswick and New Hanover counties, who are responsible for sounding the sirens.

Hearing a siren does not mean to evacuate. In an emergency, sirens are sounded as a signal for residents to tune to a local radio or TV station that would carry emergency alert messages. If sirens are heard and residents are unsure if it is a test or an emergency, they should tune to their local radio or TV station or contact the county emergency management office.

North Carolina’s oldest nuclear power plant, the Brunswick Nuclear Plant is operated by Duke Energy Progress. It began operation in 1975 on 1,200 acres just north of the town of Southport on the west bank of the Cape Fear River. North of the tract is 600 acres purchased by the N.C. State Ports Authority in 2006 and the 8,500-acre Military Ocean Terminal Sunny Point the Army’s primary east coast deep-water port opened in the 1950s.
