It is hard to dispose of this waste, creating problems. If there is a nuclear meltdown, many people will die, in painful ways. WebIn a normal thermal reactor, tin-121m has a very low fission product yield; thus, this isotope is not a significant contributor to nuclear waste. Fast fission or fission of some heavier actinides will produce 121m Sn at higher yields. For example, its yield from U-235 is 0.0007% per thermal fission and 0.002% per fast fission.
