A fertile material is the one, which can be__________________?
Correct answer: D. Converted into fissile material on absorption of neutron
- A. Fissioned by either slow or fast neutrons
- B. Fissioned by slow (thermal) neutrons
- C. Fissioned by fast neutrons
- D. Converted into fissile material on absorption of neutron
Explanation
A fertile material is not normally fissile itself but can absorb a neutron and transform into a fissile isotope, such as U-238 becoming Pu-239. Fission by thermal or fast neutrons describes fissile or fissionable behaviour, not fertility.
