I’ve been binge watching YouTube about nuclear criticality events, and I get the basic principle that you have two radioactive items and they come in contact long enough to create an event.
But I am not quite getting it. So for example, I watched a video about the demon core, but I am not sure how the shims were preventing criticality.
Thank you.

When the neutron reflector halves were closed, the neutrons had nowhere to go but back into the core itself, hitting more atoms, splitting off more neutrons, etc etc, making the core go critical. I’m no scientist or anything, but that’s what I got from what happened
