Nuclear chain reaction

Authors: Alex Tee Neng Heng, David G. Green

This is a model of a nuclear chain reaction. The red dots represent the uranium 235 atoms. When a 235 atom absorbs a neutron (small black dot), it fissions and releases 3 more neutrons and 2 fission products (yellow dot). The new neutrons in turn hit other 235 atoms, producing even more neutrons.
