Nuclear Engineer Arnie Gundersen demonstrates How Fukushima's Fuel Rods Melted and Shattered

Fairewinds' Chief Nuclear Engineer, Arnie Gundersen, conducts a field demonstration simulating the impact of Fukushima's intense heat upon Zircaloy [zirconium alloy] fuel rods. Gundersen's demonstration shows that intense heat weakens and embrittles Zircaloy changing it from a sturdy metal to a brittle oxide that is easily shattered. Images from the post accident Three Mile Island nuclear core show embrittled and broken Zircaloy fuel rods in the nuclear reactor.
