On réserve l'expression «fissile» aux noyaux lourds qui subissent la fission sous le choc d'un neutron d'énergie quelconque, même très faible. Le seul nucléide fissile naturel est l'uranium 235 présent à 0,7 % dans l'uranium naturel. Deux nucléides artificiels principaux, le plutonium 239 et l'uranium 233, sont également fissiles. L'uranium 238 [...] ne subit la fission que sous l'impact de neutrons d'énergie plus élevée, supérieure à 1 MeV, et de ce fait, il n'est pas qualifié de fissile». 3, record 1, French, - nucl%C3%A9ide%20fissile
Record number: 1, Textual support number: 1 OBS
Ce terme [«nucléide fissile»] ne s'applique pas aux nucléides dont la section efficace de fission par neutron lent est suffisamment petite pour être négligée, par exemple238U. 2, record 1, French, - nucl%C3%A9ide%20fissile
