Here is a quote from the MIT website:
Josef is the author of the essay “Why I’m not worried about Japan’s nuclear reactors”. It was an email he sent to his family in Japan. When his cousin posted it on his blog, it went viral.
Josef is working hard with a team from MIT to provide an appropriate response to the interest the post has generated. The original blog will be migrated to an MIT site, managed by a team of experts from MIT's Department of Nuclear Science and Engineering. The link will be posted here when it becomes available.
Josef is not a nuclear scientist or engineer. He is a mechanical engineer by training, working on product development processes with MIT's Lean Advancement Initiative and the MIT-KFUPM Center for Clean Water and Energy.
