Japan Earthquake: Nuclear Plants at Fukushima Daiichi
Er, I guess I wasn't clear in my earlier post - I was speaking strictly about Unit 4 SFP. Some believe the way the building appears to be damaged that it is sagging from high temperatures. I guess only time will tell. Thanks for the insight. This is a great forum. Wish I had known about...- divmstr95

Japan Earthquake: Nuclear Plants at Fukushima Daiichi
I think we are on the same page regarding the possibility of a Zr fire in the SFP. Regarding contamination levels the AMS data supports a fire. The difference between the dispersion model of an AGL release of fission products (in steam) and a fire is that a fire does not usually cause high...- divmstr95

Japan Earthquake: Nuclear Plants at Fukushima Daiichi
My understanding of the mechanism in this case is that Zirconium Hydride (ZrH2 ZrH4), produced while the plant is operating by the presence of free hydrogen from the zirc-water reaction, radiolysis of water, and corrosion control, will release H2 above 300c and is also highly flammable. The H2...- divmstr95

Any idea where these samples were taken? I see the distances. Do you know what they are in relation to? Sorry, my knowledge of Kanji is pretty poor.- divmstr95

Japan Earthquake: Nuclear Plants at Fukushima Daiichi
The methodology used to predict Tsunami considers the geology of segments along a specific seismic zone as well as several other factors (hydrographic profiles, etc.). It also considers paleotsunami information for a given area based upon previous earthquakes. It may be that the tsunami model...- divmstr95

Actually their retraction never states that they did not detect I-134. It merely states the levels stated were for a different isotope, Co-56.- divmstr95
