An situation when the temperature inside reactor core reaches such high levels that the fuel rods (made from Uranium) begin to melt their way down and destroy the reactor.
It usually happens when fuel rods cannot be cooled by a cold substance (for example heavy water) and they start vaporising every single molecule of water nearby, thus accelerating the process of building heat. The only thing operators can do now to stop it is to drop control rods, but it can be impossible because of built up pressure (that's how Chernobyl happened). When the control rods are down, the nuclear power plant crew still needs to resume water delivery to the reactor because of nuclear decay
TL:DR Nuclear fuel gets hot and burn it's way down the reactor.

Guy from Fukushima: The tsunami shut down our water pumps and now now the heat level is over the critical point. We have to evacuate whole wing of power plant and get fireman over here. Tell them there's high risk of Nuclear meltdown.

Get the Nuclear shitmug. Hym "Sam Altman is just going to buy electricity from his nuclear fusion. See? I told you that would fix the energy problems. There have also been some breakthroughs in fusion. They're working on fusion thrusters so that might be a potential out. I don't exactly know how much it would take to pivot to a fusion reactor... Or if the breakthrough was IN nuclear fusion specifically... But, yeah. Also, I think I figured out why you're having the misalignment problem (in greater detail).... Yup... That's probably right."
