      I am not a science-er but people say that fusion reactors can't have meltdowns the way fission reactors can. Something about how fission is a chain reaction that will keep going and breaking more atoms but fusion is so hard to do that when the cycle stops working in the reactor it just stops. Again my understanding of science stops at "when I try to close the door close to the hinge it's really hard so it makes me feel strong"

        Yeah this is basically true. It's also so incredibly insulated and the heat is at such a small point. Iirc it's also magnetically levitating so it isn't physically touching anything

        This same reactor has been fired up and modified many times. I recall reading an article a year or so back about them having lower temps for half a minute. Really coming along

        The problem with a fission reactor is that it's all built around a couple of tons of very angry plutonium or uranium. If things shut down that radioactive metal doesn't get any less angry.

        Fusion, from what I understand, is about using lasers and magnets to force hydrogen atoms to fuse in to helium. Even if something goes wrong, the worst case scenario is a small amount of super-heated plasma that has basically no mass and will cool down pretty quickly.

        I could be completely wrong, though. I am but a humble liberal arts major.
