Re: Japan hit by 8.9 Magnitude Quake, Tsunami Warnings In Effect
Yup.... Japan = TMI = LOFT = no serious melt down, and a shutdown....
One other thing- since this is a water cooled reactor, study Three Miles Island, and it's failure, followed by the LOFT test that was done in at the INEL. (Loss of Fluid Test, Idaho National Engineering Lab, now called INL.... I spent a summer working right next to LOFT, which was way done by then AND the TMI reactor is still in archive in the Idaho Lab)
Basically, the "China Syndrome" would not happen- if all coolant was lost, the reactor not go super critcal, but once all fluid was lost, then the passage of ractants slows down, and the fission reaction stops. What I'm reading into the reaction isn't just a way to keep any chance of release to a minimum, but also to reduce the damage/cost due to the other damage.
Is there a risk of radioactive release- I think so, but is there a chance of "meltdown"- I don't think so.

Read this article. Fantastic explanation that should remove a lot of the fear mongering and misinformation out there about the nuclear aspect of this disaster.
Granted, this is a dynamic situation and conditions can easily change. But it sounds like the plants can suffer a complete meltdown and be "fine". They were designed to handle a complete meltdown with complete cooling failure. The controlled releases of steam and other gases (including hydrogen/oxygen) are a good thing. The explosions didn't appear to damage the "last resort" containment vessel.
