Question 1

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

U + n → Xe + Sr + 2 n

The following mass values are known:

Xe:139.921620 u
Sr:93.915367 u
U:235.043924 u
n:1.008665 u
How much energy is released in this reaction? (1 u = 931.5 MeV/c2)
◦ 65.7 MeV
◦ 202 MeV
◦ 185 MeV
◦ 32.6 MeV
◦ 98.6 MeV

Question 2

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

U + n → Xe + Sr + 2 n

The following mass values are known:

Xe:139.921620 u
Sr:93.915367 u
U:235.043924 u
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)
◦ 0.57 kg
◦ 6.58 kg
◦ 1.10 kg
◦ 3.85 kg
◦ 0.66 kg
