Here is a document I wrote up for friends and family and posted on Facebook. It is from last night and a lot has happened since midnight U.S. time, but if you want a summary written in lay terms, here it is. I'll try and get an update tonight.
FYI - the key thing you want to worry about now is if the spent fuel cooling pools go totally dry. I cannot even fathom how that could be allowed to happen, but if it does, then we have a chance for a very, very significant release of radioactive material.
I don't want to come across as fear-mongering, but this continues to be bad, friends. Very bad. Still not catastrophic, but we continue to dance on the edge of the abyss.Fukushima Reactor Accidents Status Rev 0
