4. Fissile material
Option (A)
ABCD
1423
Option (B)
ABCD
2413
Option(C)
ABCD
2314
Option(D)
ABCD
1324
Correct Option:
(C)
Question Solution:
Fissle Vs fissionable : “Fissle” is distinguish from “fissionable”. “Fissionable” are any material with atom that can under go nuclear fission. “Fissle” is defined to be material that are fissible by neutrons with low kinetic energy. Fissile thus, is more restrictive energy. Fissile thus, is more restrictive then fissionable-at though all fissile material are fissionable, not all fissionable material are fissionable, not all fissionable material are fissionable, not all fissionable material are fissile. Notable, U-238 is fissionable but not fissile.
