Re: Fukushima not a big enough warning ?
'Faux Science...' offered, "...Fission byproducts include explosive Hydrogen..."
Not quite. Zirconium (used to clad fuel rods), when overheated due to cooling failure, draws oxygen from any water or steam, thus emitting hydrogen.
No different than iron really. Circa 1780s, Lavoisier produced hydrogen by passing water (steam) through an iron tube heated to incandescent in a fire.
