Power failure forces reactor shutdown at Brunswick plant, Southport

Progress Energy shut down Unit 1 of the Brunswick Nuclear Plant on Thursday after a disruption in the electricity supply at the Southport power plant, spokesman Ryan Mosier said.

Shortly before 7 p.m. Wednesday, the company told the Nuclear Regulatory Commission, an electrical connector – or bus – providing power for non-nuclear systems for both of the plant's nuclear reactors failed.

One of the systems that lost power maintains pressure in the emergency core cooling systems for both reactors, Mosier said.

The loss of power to this system resulted in a low discharge pressure alarm for both units, requiring shutdown of the reactors starting a few minutes after the initial failure, the event report stated.

After about four hours, temporary power was provided to both cooling systems, allowing the shutdown of Unit 2 to be terminated and the unit to be returned to full power. Read More
