* Workers felt quake at nuclear power plant in Arizona
* No damage to Palo Verde, San Onofre or Diablo reactors
NEW YORK Dec 31 A moderate earthquake that
rattled both sides of the U.S.-Mexican border caused no damage
to nuclear power plants in nearby Arizona and California.
However, workers at the Palo Verde nuclear plant in
Arizona, about 50 miles (80 km) west of Phoenix, felt the
5.8-magnitude quake on Wednesday, the plant's owner told the
U.S. Nuclear Regulatory Commission.
The earthquake did not register on the plant's seismic
The 3,872-megawatt plant declared an unusual event, which
is the lowest of the NRC's four emergency classifications.
Workers found no unusual conditions or damage to plant

city of Mexicali, the capital of the Mexican state of Baja
California, about 200 miles (321 km) southwest of the Palo
Verde site. [ID:nN30153974]
All three reactors at Palo Verde continued to operate at
full power throughout the event.
The next closest nuclear plant, San Onofre, which is
located along the California coast between Los Angeles and San
Diego, did not issue any reports to the NRC. One reactor at San
Onofre continued to operate at near full power (99 percent),
while the other has been shut since late September for planned
refueling and steam generator replacement.
The Diablo Canyon nuclear plant on the California coast
between Los Angeles and San Francisco did not issue any reports
to the NRC either. The two reactors at Diablo Canyon continued
to operate at full power.
Palo Verde plant is owned by Arizona Public Service, a unit
of Pinnacle West Capital Corp (PNW.N).
