The neutrons released by each fission reaction can go on to create further fissions, like a chain that is linked several times – from each chain comes two more
The diagram shows the nuclear fission process for an atom of uranium-235.
Complete the diagram to show how the fission process starts a chain reaction.
Step 1: Draw the neutrons to show that they hit other U-235 nuclei
Step 2: Draw the splitting of the U-235 nuclei to show they produce two or more neutrons
You need to be able to draw and interpret different diagrams of nuclear fission and chain reactions. Generally, things move to the right as time goes on in these diagrams, but it is important to read all the information carefully on questions like this.If you have to draw a diagram in an exam remember that the clarity of the information is important, not how pretty it looks!
Diagram of a Nuclear Reactor. The overall purpose of the reactor is to collect the heat energy produced from nuclear reactions
Purpose of a control rod: To absorb neutrons
The purpose of a moderator: To slow down neutrons
