Which isotope of uranium is easily fissionable and why 
Asked by lovemaan5500 | 16 Mar, 2018, 03:30: PM
answered-by-expert Expert Answer
Uranium has two isotopes, U235 and U238. U235 is easily fissionable because slow neutrons(neutrons having thermal energy) can cause fission. 
But for U238, we need fast neutrons, i.e., neutrons of energy 1 MeV  to cause fission
