Cryptome.org has the paper prepared by the NRC Reactor Safety Team for their team currently in Japan. It gives the assessment of the plant's reactors and recommendations.
New York Times wrote an article based on this document. Let me know if you see anything that hasn't been reported in the NYT article. I'm reading now.
By the way, TEPCO ordered a flyby by an unmanned helicopter of the Reactors 1 through 4 on April 10. I'm waiting for that video to show up on Cryptome, hopefully soon.
