Inspectors with the Nuclear Regulatory Commission say they don't yet know why a crane collapsed at Arkansas Nuclear One, killing a worker.
Wade Walters died March 31 after a 525-ton piece of equipment fell on top of him. Eight others were injured.
The Nuclear Regulatory Commission held a meeting Thursday in Russellville to discuss the results of an inspection it conducted after the fatal accident.
Commission branch chief Geoffrey Miller says the crane should have been able to handle the weight and that investigators still don't know why it failed.
Miller says the inspection found that Arkansas Nuclear One responded properly to the accident.
An attorney representing Walters' family tells the Arkansas Democrat-Gazette that relatives are still in "complete shock" after the fatal accident.
