Oscar Wildcat - 2011-03-13 The cores were exposed about a foot above the cooling water at this point. Core temps reached sufficient heights to cause the cooling water to dissociate into H2 and O2 gas. It's claimed the gas explosion didn't destroy the containment vessel, but the source of the H2 and O2 gas was the core melting down. Infinite evils stars, this.
Meatsack Jones - 2011-03-13 I could not get to the link, but yes, the problem is the zicronium they use in the vessel for reinforcement. It turns into zicronium oxide and releases hydrogen.
I would hope they knew this, and took into account that the benefits out weighed the risk of a hydrogen blast. If not...silly engineers.
Oscar Wildcat - 2011-03-13 I didn't read the link either, but that argument is silly. I'll buy that the singlet O-'s recombine with the zirconium to form an oxide preferentially to forming O2 though. But it's the cooling H2O that is the source of the H2. Jeeze, you people.
