U-238 is also fissionable. U-235 is fissile, however, which means a neutron with no additional velocity will cause it to fission. Close. Fissile materials will undergo fission with any velocity neutron.

Yeah, but absorption probablity goes up considerably as nuetron energy decreases into the thermal range.
