Controlled+chain+reaction

=Controlling chain reactions= In order to control chain reactions it is necessary to control the number of neutrons released in Nuclear fission to ensure that for each one fission only one further fission will occur. In this way the reaction will be sustained and not run out of control.

Here is a presentation on Controlling chain reactions by Matthew Boulton, Joshua Cooper, George Gallagher, Jonathon Griffiths and Dharmveer Sharma.[|Controlling nuclear chain reactions.ppt]

There is also a sheet you can follow to demonstrate how chain reactions occur [|Bunch of dominos.doc]
