Nuclear Engineer Arnie Gundersen demonstrates How Fukushima’s Fuel Rods Melted and Shattered
Nuclear engineer Arnie Gundersen demonstrates how Fukushima’s fuel rods melted and shattered from Fairewinds Associates on Vimeo.
Arnie Gundersen conducts a field demonstration simulating the impact of Fukushima’s intense heat upon Zircaloy [zirconium alloy] fuel rods. Arnie shows how intense heat will weaken Zircaloy changing it from a sturdy metal to a brittle oxide that is easily shattered.
