Nuclear Fission advice please?

See if each time the 235U nucleus fissions, 2.5 neutrons are released, and there is one millisecond between each generation (you'll need a good clock for that one), how many of them neutrons are free after an eighth of a second (125 milliseconds) of a runaway reaction that is initiated by one free neutron? (I expect this will be an extremely large number).
