Arkansas Nuclear One Unit 2 Back on Grid

Russellville, AR - Arkansas Nuclear One’s Unit 2 was reconnected to the grid on Sunday, April 28 at 3 p.m. CST. Unit 2 has been offline since March 31 when it shut down automatically when a lift carrying a replacement stator collapsed as it was moving the component out of the turbine building, a non-nuclear part of the plant. Since that time the unit has undergone extensive evaluations involving multiple third-party experts to ensure the safe and reliable operation of the plant before being brought online.

ANO is a dual unit facility owned by Entergy Arkansas, Inc. The event occurred at 7:50 a.m. CST on Sunday, March 31 as ANO’s Unit 1 was conducting planned refueling activities. Unit 2 was operating at full power and automatically shut down as designed when the event occurred.¬† There was no radiological release and no impact on public health or safety during the event.

The plant entered into a notification of unusual event, the lowest of four emergency classifications designated by the Nuclear Regulatory Commission, because of damage to a breaker cubicle. The plant exited the notification of unusual event at 6:21 p.m. that day after stabilizing power supplies.

The industrial incident resulted in one fatality, as well as injuries to eight other contract workers. All injured workers have been treated and released from the hospital.

Further evaluation will be required before restarting Unit 1, where damage evaluation, repair estimates and rescheduling the unit''s refueling activities will take additional time.

ANO Site Vice President Jeremy Browning said, “Entergy is committed to the safe operation of Arkansas Nuclear One, and our comprehensive and systematic approach to returning Unit 2 to service exemplifies that commitment.”
