Uranium-238 is in principe wel splijtbaar, maar - in tegenstelling tot uranium-235 - niet in staat een kettingreactie van kernsplijtingen in gang te houden. Het is echter in staat om een traag neutron in te vangen. Na het tweemaal ondergaan van bètaverval ontstaat plutonium-239, dat wel een kettingreactie in stand kan houden.
