"Critical mass" is the minimum mass of nuclear fissile material required for the_______________________?
Correct answer: C. Sustainment of chain reaction
- A. Economic power generation
- B. Power generation on commercial scale
- C. Sustainment of chain reaction
- D. None of these
Explanation
Critical mass is the smallest quantity of fissile material in which each generation of neutrons can produce enough further fissions to maintain a self-sustaining chain reaction. It is not defined by commercial or economic power output.
