Question

Nuclear fission reactions are :

• A. uncontrolled in atom bomb
• B. controlled in nuclear reactors
• C. auto catalytic reaction
• D. none of the above

Answer 1

Answer: (A), (B), (C)

controlled in nuclear reactors
uncontrolled in atom bomb
auto catalytic reaction

Binding energy per nucleon suggests that nuclides with a mass larger than about 130 amu should spontaneously split apart to form lighter, more stable, nuclides.
Due to uncontrolled nuclear fission, atomic bomb become more dangerous and its controlled process is used in reactor to produce energy.
