Also U235 (Reactor fuel/Bomb grade) U238 (Basically inert) Pu239 (Better Reactor fuel/Bomb grade)
+1 But plutonium can only be created in a nuclear reactor when uranium 238 absorbs neutrons and becomes neptoneum which quickly decays into plutonium 239. Also natural uranium is a split between 99.28% 238 and 0.72% 235. But now you know. Otherwise I like to see interest in this, so keep it up.
