I still stand by my position that as we find out more the situation is more worrying. Also the assurances and in fact all communication around the subject seem unconvincing.
Cosmic Variance is a science blog I have been reading off and on for many years. It's written by a group of physicists, and is currently hosted by Discover Magazine. Today's item was written by Daniel Holz who is a Feynman Fellow at Los Alamos. He says:
The latest claim (by the Chairman of the United States Nuclear Regulatory Commission) is that the storage pool at the #4 reactor has little to no water. If true, this is a very ominous development. This is by far the most dire situation on the planet at the moment. The world’s resources are focused on this problem. Millions of lives potentially depend upon the outcome. And, thus far, progress has been haphazard and halting, despite heroic efforts on the part of the Japanese crew. The engineering challenges may simply be too great.
He outlines a worst-case scenario, which I won't quote as he considers it unlikely, and concludes.
The best-case scenario, and probably most likely, is that the Fukushima-Daiichi plant will limp along, without any catastrophic event.
Of what I have read recently, this is the type of message I have found most convincing. I don't think an evaluation of the likelihood of catastrophe in this case, or the safety of nuclear power in general, is affected by any comparison with other energy sources. Evaluation should be prior to comparison.
Also, this situation confirms my belief that authorities should be more honest and open about problems, and information in general. The result of the type of thing that is happening here is a permanent legacy of suspicion. My generation were fed a pack of fibs in school about various issues such as drugs, and I think we are a suspicious bunch now. Feed more lies, teach a blanket mistrust.
