Industrial Accident at ANO-1



Significant Industrial Accident at Arkansas Nuclear One

Russellville, Ark. – A significant industrial accident occurred at Arkansas Nuclear

One at approximately 7:45 a.m. There has been one confirmed fatality and three additional

injuries. The injured employees have been transported to a nearby hospital. The accident

occurred when a generator stator fell as it was being moved out of the turbine building.

Unit 1 is in a refueling outage and Unit 2, which was operating at full power, automatically

shut down. Both plants are in a stable shutdown condition and there is no danger to the

public. The plant is in an unusual event classification, the lowest of four emergency

classifications designated by the Nuclear Regulatory Commission. Additional staff has

been brought to the site to manage the situation.

Jeff Forbes, executive vice president and chief nuclear officer said, “We are deeply

saddened by what has happened today. Our greatest sympathy is with the family and friends

of the employee who lost his life, and with those who sustained injuries. I also want to

express my sorrow and support to all those who work at Arkansas Nuclear One. I know this

is especially hard on them.”

  1. My sympathies go out to the families, but the company shut down an o.k. operating unit for a untied unrelated maintenance-like accident? Would a oil or gas plant be shut down inthe same situation? (seriously doubt it). What else can the jitters-fanned public think but that SOMETHING NUCLEAR was responsible for this death if they had to shut a unit down. Are the rules pertaining nuclear plant operations that overextended? Tell me where I'm off the mark here!

    1. Unit 2 tripped due to the accident. The stator damaged the bus that powered Unit 2's reactor coolant pumps. That is an automatic trip! Unit 2 automatically shut down. It was not a management decision!

    2. Unit 2 tripped automatically due to a loss of power to the reactor coolant pumps. The stator damaged some electrical busses. Entergy will release more details when they can; remember , multiple investigations will be occuring. Insurance, OSHA, the NRC, and our own internal investigation to find out why this occured. It will take some time; but the Nuclear Industry is very thorough. We never want a repeat occurance of any accident. And contrary to some opinions, we are very transparent. All you have to do is ask for the info from us ( the industry) or the NRC. I do not work at ANO, but I do operate another entergy reactor. I am deeply saddened by the loss of fellow nuke worker.

    3. Thanks for the commentary -- the NRC has released exactly these facts on its blog just a short while ago, which I've pointed up in a new post. One thing is for sure - there must have been more than one pair of eyes on the rig when it let go, so it should not be difficult to state exactly what happened.

  2. The second unit was forced to shut down, we think, because of either damage or shock. There are a number of unconfirmed (inside) reports I've seen and heard about damage inside the turbine building, and possible projectile damage to various areas of the plant. We won't know for sure exactly what occurred until Entergy decides to reveal the details. I do expect that to happen soon enough.
