Japan Earthquake: Nuclear Plants at Fukushima Daiichi
This may well be a naive reaction, but it seems to me that the obvious thing to do with the radioactively contaminated water in the turbine buildings is to pump it back into the reactors. Is there something wrong with that action? If/when they are able to re-establish core cooling, perhaps...- fusefiz

Japan Earthquake: Nuclear Plants at Fukushima Daiichi
| http://www.nytimes.com/2011/03/26/world/asia/26japan.html?_r=3&hp=&pagewanted=all A senior nuclear executive who insisted on anonymity but has broad contacts in Japan said that there was a long vertical crack running down the side of the reactor vessel itself. The crack runs down below the...- fusefiz

Japan Earthquake: Nuclear Plants at Fukushima Daiichi
| http://www3.nhk.or.jp/daily/english/25_10.html The company says 3.9 million becquerels of radioactive substances per cubic centimeter were detected in the water that the workers were standing in. That is 10,000 times higher than levels of the water inside a nuclear reactor in operation...- fusefiz

Japan Earthquake: Nuclear Plants at Fukushima Daiichi
Where did UCS/All Things Nuclear find their information for the number of fuel elements in reactor 4's spent fuel pool? From memory, I believe their first number referenced two newspaper articles in Japanese. Again, from memory, I believe this was the number picked up by the NY Times (1479): |...- fusefiz

IR for reactor 3 -- I believe this indicates 62 C over the fuel pool, 128 C on the other side of the reactor head: | http://www.welt.de/multimedia/archive/01340/Fukushima_hoch_DW__1340857z.jpg Interesting picture here -- I do not believe the crane and cars are at reactor ground level, but...- fusefiz

Japan Earthquake: Nuclear Plants at Fukushima Daiichi
If water has been covering the fuel in the reactor 4 pool, what could have generated the hydrogen? I have been reading this thread for most of the week and wondering myself. Today I discovered the French analysis, which is the most coherent treatment I have found. I have almost no time now...- fusefiz
