fissionable

Can be split

Fissionable describes material capable of undergoing nuclear fission—the splitting of atomic nuclei that releases enormous energy.

The term applies primarily to isotopes like uranium-235 and plutonium-239 used in reactors and weapons: fissionable material, fissionable fuel.

The word is nearly synonymous with fissile, though physicists sometimes distinguish between them technically.
