Web236 U is neither a fissile isotope nor a fertile isotope. 236 U is fissionable only by fast neutrons. Isotope 236 U is formed in a nuclear reactor from fissile isotope 235 U. 236 U decays via alpha decay to 232 Th with a half-life of ~2.3×10 7 years. 236 U occasionally decays by spontaneous fission with a very low probability of 0.00000009%.
