Meltdown

From Biology-Online Dictionary

meltdown

(Science: radiobiology) In a fission reactor, if there is insufficient coolant or the fission chain reaction proceeds too rapidly, heat can build up in the reactor fuel, causing it to melt. In extreme cases the whole fission core can melt down to (or even through) the reactor floor. Fusion reactors are not vulnerable to this.
