As part of an ongoing series of corium experiments our research team has been doing, the newest experiment created a quite unusual result. The newest experiment, the fifth in a series conducted by Edano, took the top range of assumed melt mass and ran the experiment with a sustained high heat. Upon completion it was noticed that a modest amount of the lead had left the pedestal but what was in the pedestal was much more interesting! A perfectly formed elephant’s foot was found to have taken place in the pedestal. An elephant’s foot is the name given to an unusual corium melt structure found in Chernobyl.
