Question

U-238 will undergo fission by

  1. Slow neutrons alone
  2. Fast neutrons alone
  3. Either fast or slow neutrons
  4. Medium energy neutrons

hintHint:

The use of fast neutrons in 'fast reactors' allows for the production of more fissile nuclei than are destroyed.

The correct answer is: Fast neutrons alone


    • The absorption of at least one neutron per fission by an uranium 238 nucleus transforms this uranium 238 into a fissile plutonium 239 nucleus.
