Source sentences:
text: By placing the fission fuel in water, the probability that the neutrons will cause fission in another U-235 is greatly increased, which means the level of enrichment needed to reach criticality is greatly reduced.
text: Thermal neutrons are more likely than fast neutrons to cause fission.
text: In most cases, the fuel mass is separated into a large number of smaller fuel pellets and then surrounded by some form of neutron moderator that will slow the neutrons, thereby increasing the chance that the neutrons will cause fission in 235U in other pellets.
text: Fission reactions emit neutrons at various speeds, which can fission other atoms: slow (thermal) neutrons can readily cause fission in nuclei of fissile isotopes; fast neutrons can cause fission in nuclei of fertile isotopes.
