Arnie Gundersen of Fairewinds Associates is a nuclear expert hired by activists as part of their campaign to shut down the San Onofre Nuclear Generating Station.
He authored several technical papers on failures of San Onofre's steam generators, the regulatory process and Southern California Edison's management of the plant.
The plant shut down more than a year ago after a small leak of radioactive steam revealed crucial design flaws throughout the four steam generators at the plant from newly installed components that had been operating for only a couple years.
Until Friday, Edison wanted to restart half the plant at partial power.
