The US Nuclear Regulatory Commission has begun a special inspection at Unit 1 of the Farley nuclear power station in Alabama due to a partial loss of offsite power and subsequent issues with a turbine-driven auxiliary feed pump.

On 3 August, Unit 1 automatically shut down due to the partial loss of offsite power. One of the emergency power buses, which provides electricity to safety equipment, also lost power.

The plant’s emergency diesel generator automatically started, restoring power to the emergency bus, and the auxiliary feed system provided reactor cooling, as designed, placing the plant in a safe condition.
