WebNuclear fission Fission may take place in any of the heavy nuclei after capture of a neutron. However, low-energy (slow, or thermal) neutrons are able to cause fission only in those isotopes of uranium and plutonium whose nuclei contain odd numbers of neutrons ( e.g. U-233, U-235, and Pu-239). WebTime of Reaction. The released neutron travels at speeds of about 10 million meters per second, or about 3% the speed of light. The characteristic time for a generation is roughly the time required to cross the diameter of the sphere of fissionable material. A critical mass of uranium is about the size of a baseball (0.1 meters).
