About Corium
A lava-like material created during meltdown of a nuclear reactor. "It consists of a mixture of nuclear fuel, fission products, control rods, structural materials from the affected parts of the reactor, products of their chemical reaction with air, water, and steam and, in the event that the reactor vessel is breached, molten concrete from the floor of the reactor room." (Wikipedia)
Composed primarily of uranium and zirconium oxide phases, but if silica is introduced from structural materials such as sand and concrete silicates of Zr and U can form.
As of 2019 three incidents worldwide are known to have generated corium:
Three Mile Island, Pennsylvania, USA - March 1979
Chernobyl, Ukrainian SSR (now Ukraine) - April 1986
Fukushima, Japan - March 2011
