On March 21, Stanford University presented an invitation-only panel discussion on the Japanese crisis that featured Alan Hansen, an executive vice president of Areva NC, a unit of the company focused on the nuclear fuel cycle.
“Clearly,” he told the audience, “we’re witnessing one of the greatest disasters in modern time.”
Dr. Hansen, a nuclear engineer, presented a slide show that he said the company’s German unit had prepared. That division, he added, “has been analyzing this accident in great detail.”

Stanford, where Dr. Hansen is a visiting scholar, posted the slides online after the March presentation. At that time, each of the roughly 30 slides was marked with the Areva symbol or name, and each also gave the name of their author, Matthias Braun.
The
posted document was later changed to remove all references to Areva, and Dr. Braun and Areva did not reply to questions about what simulation code or codes the company may have used to arrive at its analysis of the Fukushima disaster.

A Greenpeace letter - Areva at the heart of Fukushima’s explosive reactor
OWNI.eu :: As early as May 2001, Greenpeace advocated that nuclear reactors in Fukushima should abandon using the nuclear fuel MOX. As shown in the letters (Scribd.com embedded) sent to the American Nuclear Regulatory Commission, the issue pertains to Fukushima’s boiling water reactors.
Re: Greenpeace comments regarding the Nuclear Regulatory Commission's (NRC) scoping process in preparation for the competition of the Plutonium (MOX) Fuel Environmental Impact Statement (EIS)
In Greenpeace’s crossfire is Areva, the main supplier for the power plant in Fukushima. They are subsidized by Melox, which holds 95% of the market shares for MOX
