Russellville, Ark. – Arkansas Nuclear
One’s Unit 1 reconnected to the grid at 10:43 p.m. CDT Wednesday after a major
restoration effort involving ANO and Entergy Nuclear workers, government
officials and multiple third-party experts.
“We’d like to thank the community for
their outpouring of support at both the local and state levels,” said Jeremy
Browning, ANO site vice president. “As a corporate neighbor of the Russellville
area, your confidence in us is deeply appreciated. The ANO team is committed to
the safety of this plant, the people who work here and those who live in this
Prior to restarting, ANO’s Unit 1
required extensive restoration efforts, including damage evaluation, repairs to
non-nuclear plant components and rescheduling the unit’s refueling activities.
The restoration was necessary following the collapse of a contractor’s crane
while moving a generator stator out of the turbine building, a non-nuclear part
of the plant.
All told, Entergy employees and
contractors devoted more than 790,000 hours of effort to the unit’s safe return
to service. The restoration effort saw 55 tons of steel erected and 93 cubic
yards of concrete placed – in addition to hundreds of cable installations,
switchgear replacements and electrical repairs.
ANO workers developed a comprehensive
startup monitoring plan to ensure the plant achieved a safe and controlled
restart. The plan focused on both equipment and systems, including walk-downs by
plant staff, extensive monitoring and testing activities, increased training,
augmented crews and increased oversight. These plans were developed and
challenged by both internal and external ANO subject matter experts.
Unit 1 has been offline since Sunday,
March 24 when the plant entered its scheduled refueling outage.
