Question
U-238 will undergo fission by
- Slow neutrons alone
- Fast neutrons alone
- Either fast or slow neutrons
- Medium energy neutrons
Hint:
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.
