Officials at Duke Energy’s (NYSE: DUK) Harris nuclear power plant declared an Alert at 3:05 a.m. August 8 when a switchgear explosion resulted in the loss of power to non-safety related electrical distribution equipment.

In a filing with the Nuclear Regulatory Commission, Duke reported no offsite assistance was requested and verified there was no fire associated with the explosion in the electrical bus.

After an inspection of plant equipment revealed no threat to the safe operation of the facility, Harris personnel terminated the Alert condition. The unit is stable at a reduced power level of 92 percent while recovery actions continue.

There has been no release of radioactive materials as a result of this event.

An Alert is the second in increasing significance of four nuclear emergency classifications. This classification is used to describe conditions that require emergency response agencies to be in a heightened state of readiness, but pose no threat to public safety.

The Harris nuclear power plant is a single-unit facility located on Harris Lake, near New Hill, N.C. The plant began commercial operation in l987 and has a rated capacity of 928 megawatts. Harris is jointly owned by the North Carolina Eastern Municipal Power Agency and Duke Energy.
