Neutrons emitted from splitting atomic nuclei are usually too fast to trigger subsequent fissions, but water has a knack for slowing down neutrons. Two basic outcomes are possible: Either the two nuclei fuse into a lasting larger one, or the emerging heavy nucleus quickly splits, or fissions, into two pieces. Eventually, if rotated fast enough, the nucleus will deform so much it fissions, or breaks in two. |
