CONT

U-235 prefers cold neutrons; Pu-239 strongly prefers hot neutrons. Thus, for fresh fuel, increasing thermal neutron temperature decreases reactivity. For equilibrium fuel, reactivity increases with increasing thermal neutron temperature.

CONT

L'uranium 235 préfère les neutrons froids; le plutonium 239 a une préférence marquée pour les neutrons chauds. Ainsi, pour le combustible neuf, l'augmentation de la température des neutrons thermiques diminue la réactivité. Pour le combustible à l'équilibre, la réactivité augmente en fonction de l'augmentation de la température des neutrons thermiques.
