Source sentences:
text: However, too few of the neutrons produced by 238U fission are energetic enough to induce further fissions in 238U, so no chain reaction is possible with this isotope.
text: About 0.65% of the neutrons produced by 235U fission, and about 0.20% of the neutrons produced by 239Pu fission, are not produced immediately, but rather are emitted from an excited nucleus after a further decay step.
text: 238U is not capable of sustaining a nuclear fission chain reaction, because too many of neutrons produced by fission of 238U have lower energies than original neutron.
text: However, too few of the neutrons produced by 238U fission are energetic enough to induce further fissions in 238U, so no chain reaction is possible with this isotope.
