Academics

When a neutron collides with a uranium-235 nucleus it can induce a variety of fission reactions. One such reaction is

235/92U + 1/0 n → 140/54 Xe + 94/38 Sr + 2 1/0 n

The following mass values are known:

140/54 Xe: 139.921620 u

94/38 Sr: 93.915367 u

235/92 U: 235.043924 u

1/0 n: 1.008665 u

What mass of uranium is needed to produce a 10-kiloton yield? (1 u = 931.5 MeV/c2 = 1.66054 × 10-27 kg, 1-kiloton yield = 5.0 × 1012 J)
