| Keywords: Fission chain reaction.svg Schematic diagram of a fission chain reaction Based roughly on the illustration in the Smyth Report 1945 Caption <br/> A uranium-235 atom absorbs a neutron and fissions into two new atoms fission fragments releasing three new neutrons and some binding energy One of those neutrons is absorbed by an atom of uranium-238 and does not continue the reaction Another neutron is simply lost and does not collide with anything also not continuing the reaction However one neutron does collide with an atom of uranium-235 which then fissions and releases two neutrons and some binding energy Both of those neutrons collide with uranium-235 atoms each of which fission and release between one and three neutrons and so on Created by User Fastfission in Adobe Illustrator Fastfission If you want to credit someone credit Wikimedia Commons Otherwise don't credit anyone that's fine by me --Fastfission 15 02 14 April 2008 UTC Nuclear explosion physics Nuclear fission | ||||
