WINTERSBURG, Ariz. — Palo Verde Nuclear Generating Station engineers are
studying how to repair a tiny leak of water from the reactor vessel of one of
the plant’s three units.
Officials said the situation doesn’t represent a public health threat.
Plant spokesman Alan Bunnell said evidence of the leak consisted of residue
around a pipe. That pipe is on the outside of the bottom of the reactor vessel
that normally holds the unit’s radioactive fuel.
Bunnell and a federal inspector said the leak was discovered during an
inspection after the unit shut down Oct. 5 for refueling. And
Bunnell said operators believe the leak resulted from a tiny crack in the
welding that connects the pipe to the reactor vessel.
He said repairs could extend the scheduled 30-day outage by 30 more days.
The plant is located about 45 miles west of downtown Phoenix.
