Fusioniteliquid

Fusioniteliquid is a type of 'water' that generates steam when put into U-235-Urods, it will generate heat causing it to melt;

which spews 400r/h per hour. But if freshwater reaches the substance when it's processing heat, it will suddenly turn into "Magma" or "Lava" which creates a radioactive substance called

"Corium". The Corium is filled with tons of radioactive material, and billions of atoms splitting apart, which gave birth to Fusioniteliquid.

The element is held for being responsible of Fukushima's magma corium and Chernobyl's elephant foot.

Mostly found in Nuclear power plants, disposed in water to cool down, Rarely found in volcanoes that generate full-capacity blasts.

Known for being the most deadliest material than Polonium. Standing next to it for just three seconds would be fatal.
