Fertile material

Transmutation flow between 238U and 245Cm in LWR.[1] Speed of transmutation varies greatly by nuclide, and percentages are relative to total transmutation and decay. After removal of fuel from reactor, decay will predominate for shorter-lived isotopes such as 238Pu, 241Pu, 242–244Cm; but 245–248Cm are all long-lived.

Fertile material is a material that, although not fissile itself, can be converted into a fissile material by neutron absorption.
