  3. When the reactor goes "critical" the neutrons cause more and more atoms to disintegrate. In other words those neutrons initiate more and more fissions that create more and more neutrons. If it runs out of control, boom.

  8. The control rods can be inserted to absorb some neutrons and avoid the situation running out of control.

  9. You want just enough neutrons to keep the reactor going ("critical"), but more and you are building a bomb (in the limit). That is called "supercritical")
